The feeling of CES exhibition has always been a gathering of all kinds of whimsy, new technology and new inventions. Here you can see the refrigerator showing the freshness of each food, and the bracelet that records the life track and physical condition. Of course, the electronic technology and technology of vehicles that make us safer and smarter in the future are also essential. This article will let us look at these technologies that seem to be a little bit strange, don't laugh at them. Now it seems that the technology is not mature enough, and the future is likely to come to your side to change your life.

â–  Audi laser headlights

The shape of the light group has always been an important means for designers to create the "characteristics" of the appearance of the vehicle. It is believed that the first reaction in the minds of many people will associate with the Audi brand. In the era of LED light sources, designers have combined this technology with aesthetic design, allowing the light group to give different qualities to different models of the Audi brand. In a way, this has almost brought a revolution to the lights. I know that you may still be immersed in the beautiful atmosphere created by the light belt shape. Wake up first, this time CES, Audi has brought us laser headlights.

Helping the driver to shine and analyze the technology of 2014CES exhibition

In fact, it is a new technology, and some are not very accurate, because as early as 2011, Audi has disclosed its laser fog light technology. If the application of the laser source in the position of the fog lamp is only an attempt to explore its possibilities, then the application of this Audi to the position of the headlights indicates that they are confident in the technology.

After reading the structure, let us look at the advantages of laser headlights. Compared with LED light groups, laser headlights not only have the same advantages as LED light groups, such as fast response, low brightness attenuation, small size, low energy consumption and long life. Compared to LED headlights, laser headlights have an advantage in terms of volume. The length of a single laser diode component can already be 10 microns, which is only 1/100 of the size of a conventional LED component. This change will be left to the designer. More space for talent.

Helping the driver to shine and analyze the technology of 2014CES exhibition

Another significant advantage of laser headlights is that in terms of luminous efficiency, the luminous efficiency of general LED lighting can reach about 100 lumens per watt, then the laser diode component can reach about 170 lumens per watt, which means that when the same lighting conditions are met When using laser headlights, the energy consumption is less than 60% of LED headlights, which further reduces energy consumption and is more in line with the future energy saving and environmental protection trends of automobiles.

Comments:

Although the use of lasers as a light source has many benefits, it still takes time for this technology to really come to us. First, Audi needs to consider whether the laser headlights will bring about a significant increase in cost. Secondly, this technology will go through the EU. Various safety assessments.

Helping the driver to shine and analyze the technology of 2014CES exhibition

By the way, Audi's competitors are not idle. BMW's actions in this field are not just a celebratory news at CES. The laser headlights are already on the production version of the i8. . However, whether it has passed the safety assessment of the US and relevant EU departments is not known.

â–  Kia driver medical examination system

When it comes to safe driving, we always mention that it is important to concentrate on driving. It is not recommended to drive a vehicle when the condition is not good. When driving, our body has a problem that is likely to cause a major accident. For this reason, Kia has developed a health check function for the driver when driving, and the principle is similar to that of the partial fatigue detection system.

Helping the driver to shine and analyze the technology of 2014CES exhibition

The health check-up function of the car exhibited by Kia at this CES is realized by the driver's thumb on the sensors located on both sides of the steering wheel. After selecting this function on the central control screen, the user can put the thumb in the induction. Some data detection is implemented on the device. Such a detection device is similar to a health detection device in a gym, and can check the user's current fat amount, heart rate, and the like.

Comments:

Through this set of equipment, users can understand their current physical condition more easily and quickly. In the future, they will cooperate with this year's CES show's smart bracelet equipment and App software. The driver's real-time physical condition and judge whether to drive and whether to go to medical treatment. The organization will become very relaxed.

â–  Atmel releases car center console with curved touch screen

Despite the rapid development of technology, the center console of the vehicle has a lot of functions and buttons, so its shape has rarely broken. Is it a bit of a solid LCD screen on the TESLA MODEL S that is the shape of the center console in the future? Of course not, industrial design can also become more aesthetic. Atmel's concept of the car's center console "Atmel AvantCar" at CES has driven its development. The goal of this product is to help designers create a more sleek center console through touch screens, touch button technology, and semiconductor products.

Helping the driver to shine and analyze the technology of 2014CES exhibition

The Atmel AvantCar features a metal-grid curved touchscreen sensor "XSense", a 12-inch touchscreen that is not only large in size but also low in power consumption. Secondly, it is equipped with a capacitive touch button and slider "QTouch", which can replace the traditional buttons and knobs to optimize the layout space.

Comments:

With XSense and QTouch technology, without the hardware constraints, the designer can give the center console a smoother surface shape, and the front storage space and seating space will be expanded.

â–  Valeo vision control technology

In order to reduce the dangers that drivers may pose to the operation of systems such as audio and air conditioning while driving a vehicle, Valeo has developed this driver assistance system. This technology enables the operation of the sound of the human body by scanning the human eye movement, that is, by interconnecting the car with the driver's eye.

Helping the driver to shine and analyze the technology of 2014CES exhibition

With the gaze camera, the driver only needs to look at the button he wants to operate, and the driver can change the radio channel and get relevant information. When this technology is integrated with the head-up digital display system (HUD), the driver can see the information he wants to operate on the dashboard control panel of the windshield without having to divert his line of sight when performing the relevant operations on the vehicle.

Comments:

You can control related functions just by looking at it. This scene may only be seen in science fiction movies, but whether the technology works well, such as how long the eyes need to look at the buttons, how high the recognition of the system is. It's not clear, and it's directly related to the final user experience.

â–  Intel introduces smart headlight technology

In 1887, the car began to assemble lighting equipment. At that time, people only installed household portable lights on the car. In the next 100 years, the development of automotive lighting equipment has not stopped, from halogen lamps to xenon lamps to LED lamps. The concept of laser headlights, the change of light source is also constantly breaking the bottleneck of the development of automotive lighting equipment, although the new lighting technology can provide better visual effects for the driver at night, but in some special circumstances, The effects of these lighting devices still have limitations, such as rain and snow at night. In this regard, Intel Corporation and Carnegie Mellon University (hereinafter referred to as CMU) exhibited their solutions in CES 2014.

When driving down in the rain and snow environment at night, the lights will be reflected by raindrops or snowflakes, which will affect the driver's line of sight. Intel and CMU have researched this direction and developed a technology called "Smart Headlight" that reduces the amount of light reflected in layers of raindrops/snowflakes to improve the driver's viciousness. Vision in weather conditions. The chief analyst of a US technology company lamented when he saw the technology: "This is very spectacular, this is a very practical technology."

Helping the driver to shine and analyze the technology of 2014CES exhibition
Helping the driver to shine and analyze the technology of 2014CES exhibition

The reason for this is to use the gap between the raindrops or the snow flakes when they fall. The system traces the falling raindrops/snowflakes through a camera and calculates their motion trajectory through the processor. At the same time, the system passes the projection. The device adjusts the positional relationship with the raindrops/snowflakes to reduce the degree of reflection of the light, so that a relatively clear view is presented to the driver. This time, Intel did not announce too much technical details.

Helping the driver to shine and analyze the technology of 2014CES exhibition

In view of the current trend of lamp development, the function of projection may be realized by LED light source in the future. Each LED component has system control. The mechanism believes that LED and image sensor can be integrated on one chip based on LED technology. In order to minimize the volume and reduce costs.

Scanning speed requirements

The response time of the prototype exhibited was 1 millisecond (the prototype in 2012 required 13 milliseconds in the whole process), and the scanning frequency of the projection device was increased from 120 Hz to 1000 Hz. In an environment with little rainfall, when When the vehicle is driving at low speed, the system can eliminate the impact of raindrops or snowflakes on the field of view from 70% to 80%. Even in the case of heavy rain, the performance will only have about 5% attenuation. However, if the vehicle is driving at a speed of 100 km/h, the vehicle will move about 28 meters per second. Obviously, this puts higher requirements on the scanning and calculation speed of the system. Although we do not recommend people to drive in rainy days. The speed is too fast, but this is indeed the main research direction of the two research institutions.

Comments:

The involvement of Intel and the IT companies such as NVIDIA and Qualcomm mentioned later will make car manufacturing interesting. The extremely high update frequency of IT products will surely set off a new storm in automotive design and manufacturing. Of course, we must also pay attention to the fact that for the user, the cost of upgrading the car is much higher than that of the IT product. How to balance this is the problem that lies in front of them.

â–  NVIDIA launches driver assistance system GPU

When it comes to NVIDIA, many gamers know that this is a world-leading graphics processing technology company, but it is difficult to connect it to the car. In fact, Nvidia has been involved in the automotive industry for a long time, providing brands such as BMW and Audi. A display chip of an in-vehicle infotainment system and an image processing chip of an active driver assisted security system. In the ongoing 2014 CES (International Consumer Electronics Show), NVIDIA launched the new graphics processor (GPU) Tegra K1 and applied it to automotive security.

Compared with the previous processing chip, Tegra K1 has stronger performance. In the radar + camera based advanced driver assistance system (ADAS) sensing system, it can realize functions including pedestrian detection, traffic identification, lane recognition, etc. For collision prevention (PCS), lane offset warning (LDW), and active cruise control (ACC) systems.

Helping the driver to shine and analyze the technology of 2014CES exhibition

NVIDIA Vice President and General Manager of the Automotive Division said: "In order to handle the continuous flow of data from the driver assistance system sensors and cameras, NVIDIA injects extremely energy-efficient supercomputer technology into the vehicle. The Tegra K1 delivers up to ten times as much as the previous mobile processor. The computing power does not consume additional energy."

Helping the driver to shine and analyze the technology of 2014CES exhibition

Comments:

There are currently more than 4 million vehicles equipped with NVIDIA GPUs in the world, and the latest Tegra K1 maintains its original energy consumption while significantly increasing processing speed, making driver assistance systems faster and smarter.

Car multimedia system

With the development of technology, the originally monotonous driving journey is becoming more and more abundant. Not everyone is a vehicle performance control, do not have to bother to remember the route, turn on the navigation and listen to the music with the help of the computer to drive safely, to the destination without looking up the neck to find the parking space, these interesting experiences I believe everyone will be willing to accept. How to improve and make the customer experience better is the focus of many car companies. At the CES show, you can see the results of many companies' efforts in this area.

â–  Qualcomm launches information processor for vehicles

In the childhood when the BP machine was still a luxury item, I never thought that one day I would use a big palm to watch movies, play games, and even know what happened on the other side of the globe. Today, more than 20 years later, more and more models are beginning to be equipped with a screen that can be touched and can control the multimedia system. However, due to cost, security and other considerations, the screens that display the in-vehicle interactive system, whether it is resolution or response speed, or software usability feels a lot different than the smartphones in our hands.

This time Qualcomm demonstrated its Snapdragon processor, which is to be launched on the vehicle. Qualcomm's highly integrated "all-in-one" mobile processor series platform now covers entry-level smartphones and even covers the entry-level smartphones. High-end smartphones, tablets and next-generation smart devices. It has powerful multimedia features, 3D graphics capabilities, GPS engine and can adapt to 3G/4G mobile broadband technology.

The future will be carried on the vehicle is the Snapdragon 602a processor, which belongs to the Snapdragon 600 series. It has four Krait cores, integrates the Adreno 320 graphics processor and Hexagon DSP, and integrates a Gobi 9×15 multimode baseband to support 3G/4G LTE networks, dual-band Wi-Fi and Bluetooth 4.0 standards. It supports a variety of operating systems, of course, the most mainstream is still the use of Android and QNX systems. It can provide car users with better 3D picture navigation, face recognition, gesture recognition and even 3D games for the rear seat display.

Comments:

Qualcomm's experience in R&D, design and manufacturing in the IT industry will greatly shorten the time from the development to the application of this automotive processor technology. This intervention is of great significance, and it is similar to Apple's involvement in the mobile phone field. For the sake of the future, in-vehicle systems will also become smaller, smarter and faster.

■ Volvo and Ericsson collaborate to develop vehicle “cloud service”

At this exhibition, Volvo, which always pays attention to safety technology, did not “show off” its safety technology. Instead, it announced the latest information on its cooperation with Ericsson in 2011 to develop “cloud technology”. In the future, Volvo models will be able to push navigation, entertainment and other information to the owner through the in-car screen, and the download of application software is also possible.

In addition, the new generation SYNC AppLink in-car entertainment communication system allows application developers to call real-time information such as driving speed, acceleration, odometer information and vehicle positioning, and integrate with the application to bring more comprehensive and personalized interaction to the owner. Connection experience.

Comments:

Although SYNC AppLink is good, if it is introduced into China in the future, localization is a problem.

â–  Mercedes-Benz launches smart watch

Mercedes-Benz showed their technological achievements to the outside world at the show. Through cooperation with Silicon Valley startup Pebble, Mercedes-Benz launched a set of wearable devices based on Pebble smart watches.

Although the cooperation with Pebble was not long, as early as 1994, Mercedes-Benz had established the first automotive technology R&D center in Silicon Valley. In December 2013, they opened a second technology R&D center. In addition, Mercedes-Benz is also actively working closely with technology companies like Apple and Google. It can be said that Mercedes-Benz has a considerable reserve capacity in automotive electronics technology.

â–  BMW Dynamic Autopilot Technology

Many manufacturers are now developing and testing related autonomous driving technologies, but this kind of testing is more based on ordinary roads and normal driving. The BMW company has demonstrated automatic driving under extreme driving conditions. driving skills.

Helping the driver to shine and analyze the technology of 2014CES exhibition

The vehicle can guarantee the driving safety of the vehicle under extreme driving conditions. The technology is mainly realized in two ways. One is to apply different braking force to each wheel through the ABS system, and the other is to use radar, ultrasonic wave and The optical camera monitors the road conditions in real time, and the feedback information will actively participate in the steering of the car. The system ensures a perfect fit between the steering wheel, the brake system and the accelerator pedal. When the vehicle has a tendency to understeer or oversteer, the system will actively intervene after accurate calculation to ensure safe driving.

Comments:

BMW is a car brand that emphasizes sports. It has entered the stage of extreme driving conditions in automatic driving, but it still seems far away from us.

New energy and environmental protection technology

In a whimsical exhibition like CES, electric cars seem to be less avant-garde. Fuel cell technology and solar technology are the mainstream here. The two companies that show them happen to be on the Pacific and the East, let us look at the different logic of thinking between the East and the West.

â–  Toyota fuel cell vehicle technology

Although the head of TESLA, Elon Musk, publicly stated that the fuel cell is bullshit, Japanese manufacturers on the other side of the globe are still developing fuel cell technology intensively. At this year's Tokyo Motor Show, Toyota exhibited the fuel cell (FCV) concept car TOYOTA FCV, which is scheduled to be launched in 2015. In addition to bringing the FCV concept car model, Toyota at the CES show announced plans to set up a hydrogen refueling station in the United States. (Note: The following pictures are from the Toyota Motor Show Toyota booth)

Helping the driver to shine and analyze the technology of 2014CES exhibition

Tip: What is Fuel Cell?

The fuel cell is literally translated into a fuel cell, which is a chemical reaction between fuel and oxidant, which is directly converted into electrical energy, but it cannot store electricity and can only generate electricity. The difference between a fuel cell and a conventional battery is that the fuel cell needs to continuously input fuel and oxidant into the battery during operation, and the fuel cell continuously supplies electric energy as long as the supply is continued.

Fuel cell advantage

Fuel cells have two distinct advantages. First, the energy conversion efficiency is high. The fuel cell directly converts the chemical energy of the fuel into electrical energy without passing through the combustion process. Another advantage is that the emission of harmful gases and noise are relatively low.

The fuel cell unit used in this concept car has an output power density of 3 kW/L, which is more than twice that of the current fuel cell stack equipped with the SUV FCV "Toyota FCHV-adv". According to Toyota, this electrode formation technology uses a platinum catalyst that can coat several μm of particle size without condensation, and has made a significant contribution to improving the output power density of the battery pack.

Helping the driver to shine and analyze the technology of 2014CES exhibition
Helping the driver to shine and analyze the technology of 2014CES exhibition

The concept car is equipped with a high efficiency boost converter (DC-DC converter) that uses a boost converter to increase the voltage of the fuel cell to increase the speed of the motor and thus increase the output power. By adopting this method, the size of the driving motor is reduced, and the number of fuel cell units is reduced, thereby realizing miniaturization of the fuel cell stack. In addition, although the miniaturization is achieved, the output power of the fuel cell stack still reaches 100 kW or more.

The time required to fill the hydrogen fuel is only about three minutes, which is about the same as that of a gasoline car. The cruising range after filling with hydrogen fuel is about 500km, and it can reach 700km in JC08 mode.

Helping the driver to shine and analyze the technology of 2014CES exhibition

On the issue of hydrogen station infrastructure construction, Toyota will use California as an example to predict. Because California has established regulations for automakers to sell a certain number of ZEVs (Zero Emission Vehicles), they are concerned about FCVs that do not emit carbon dioxide during driving. Also, the state has approved a $200 million investment to improve its hydrogen infrastructure. According to Toyota, if you use 10,000 FCVs in major California areas, you need to set up 68 hydrogen charging stations. According to the survey, Toyota is discussing with the state of California to establish 20 new hydrogen refueling stations by 2015 and 40 additional hydrogen refueling stations by 2016.

Comments:

At present, Toyota has announced that it will launch a model that uses fuel cells in 2015. However, Toyota has not announced more information on the location of the fuel cell system. Is it true that Elon Musk is accurate in the future, or that Japanese manufacturers are taking the pulse of the times? It is estimated that it will take another 10 years to know the answer.

â–  Ford C-MAX Solar Energi Solar Concept Car

Looking at the Toyota fuel cell model above, do you think this is very advanced? Ford has demonstrated the concept of solar-powered driving at this CES show, hoping to solve the pollution caused by current power generation through solar energy.

Helping the driver to shine and analyze the technology of 2014CES exhibition

After full charge, the Ford C-MAX solar concept car is expected to perform as well as the C-MAX plug-in hybrid, with a cruising range of 998 kilometers and a cruising range of 34 kilometers in pure electric mode. In addition, the model still has a charging port, and the owner can connect the car to the charging station for charging.

Comments:

The idea of ​​using a concentrating mirror to increase the efficiency of solar energy absorption is truly amazing.
