How much do you know by digging deep into the design elements of smart cars?
In fact, driving is sometimes a painful thing. Drivers tend to maintain a high concentration. They can watch six roads and listen to them. Driving for a long time can cause fatigue. In view of this, the continuous innovation of technology has led to the rise of concepts such as smart cars, car networking, and electric vehicles, with a view to bringing better driving experience, enhancing driving safety, and saving energy.
We can see that the model of future-style cars that are smart, safe, green and connected has already begun to show up. In this issue of the "Automotive Electronics Special Issue" in July , you are invited to explore new technological changes, analyze the market situation, and dig high-quality technical articles to add help to engineers and friends.
How smart is the futuristic car?
A-perceived
The so-called "perceived", that is, the transformation of the real world into a digital world, through the output of structured data, can be understood by humans and smart devices.
Let's imagine a scenario like this: When the temperature inside the car is too high in a hot summer day, the car will automatically turn on the air conditioner to cool down. Isn't that a smart car? In addition, pedestrian monitoring, lane departures, active safety, and future autonomous driving are all examples of automotive intelligence. The premise of making this all happen is the sensor.
Bosch spokesperson Florian Bosch said MEMS sensors are used in active and passive safety, powertrain and infotainment. Pressure sensors, accelerometers, and angular velocity sensors are the main applications of MEMS sensors on vehicles. As technology continues to innovate, Bosch has integrated sensors with different functions. For example, the SMI540 integrates acceleration sensors and angular velocity sensors. It can be used not only for ESP electronic stability programs, but also for airbag ECUs. Safe technical solution integration helps OEM customers achieve significant cost savings. In the future, following the craze of automated driving, automotive-related peripheral sensors such as vehicle networking sensors will also be greatly developed.

In terms of driving safety, Xu Zhibin, Marketing Manager of China Automotive Industry, Analog Devices, pointed out that in the era of smart cars, active safety technology has become a high-profile emerging field. Rollover and Stability Control (ESC) are active today. A new improvement in the security system. This requires a MEMS acceleration sensor and an angular velocity sensor to sense the body posture. “Because such sensors are often installed in locations where vibrations are harsh, sensors are required to have high vibration and shock resistance. This is a challenge for MEMS sensors.â€

B- connectable
The car network, also known as the connected car, is a hot term in the automotive industry. This year, the car networking market is expected to usher in an explosion. "Traditional" car manufacturers need not say that Apple, Google and other technology giants have also stepped into the promotion of car networking technology.
However, despite the concept of fire, most people still don't understand the concept of car networking and the concept of car networking. What exactly is the car network? No one can say clearly. So there is such a relatively straightforward science article: talk about the Internet of Things in my eyes . ( from special focus )

C-personalization
CarPlay's introduction of Siri into the car is the beginning of the car's personalization. The car in the future is a robot. When it comes to this, are you in the scene of the movie "Cars"?
With Siri, the car has a new brain that replaces the position of the previous car. It can not only listen to your commands, but also play the corresponding style of music according to the mood of your speech. It can also guess the user's needs according to the current time and current location to give the user the life service recommendation he wants.
For example, when driving, when you get to the meal, Siri can tell the owner when he is about to arrive at a restaurant that suits his taste according to the owner's preference and the mood at the time. "There is a xxx restaurant in front of you, is it right for you? Eat here?" This eliminates the cumbersome search for surrounding restaurants. Google Auto also has a similar feature. When the owner leaves the company, Google Now will actively inform the user of the newly opened restaurants or recommend some restaurants that suit the owner's taste.
Energy-saving and environmentally friendly, new energy vehicles are killed!
During the two sessions, Xi Jinping emphasized that the automobile industry is an industry with a large market, high technical content and high level of management refinement. The development of new energy vehicles is the only way for China to move from a big automobile country to a car power. It is necessary to increase research and development and study the market carefully. Develop a product that adapts to various needs with a good living policy, making it a strong growth point.
At this stage, the new energy vehicle market is welcoming a new era of “before there are generals and then pursuersâ€. In addition to the current fierce competition between the BMW i series and the Tesla Model S, Audi, Porsche and other international giants are also ready to launch a variety of models such as pure electric SUV and Tesla. Higher. Some people in the automotive industry said that the real growth of the new energy vehicle market must rely on the joint efforts of a number of traditional automobile giants. In particular, with the announcement of Tesla's patent release, it will speed up the process of rapidly expanding the new energy vehicle market.
However, with the advent of the era of giant wars and the vigorous expansion of the new energy vehicle market, the security risks that followed have also attracted much attention. Last year, Tesla electric vehicles suffered several burning accidents, and their combustion was related to lithium batteries. Then in February of this year, Tesla electric car "fired again": a Canadian Tesla Model S electric car spontaneously ignited without plugging in...
How to protect the most important security issues? What is the battery test for electric vehicles? What are the bottlenecks? What are the differences between domestic and international battery standards for electric vehicles?
Dr. Zhu Jing, Technical Manager of Battery Products Department of TÃœV SÃœD Greater China, pointed out that electric vehicles have the advantages of high efficiency, low energy consumption, low emissions and zero emissions, which have attracted the attention of all countries. The governments of the United States, Germany, Japan and China have invested a lot of money. And issued relevant policies to support, and vigorously promote the development of key components and technologies for the electric vehicle industry and electric vehicles. However, the development of electric vehicle marketization cannot rely solely on government power. The upstream and downstream enterprises in the industrial chain need to use this powerful Dongfeng to improve performance, ensure safety, reduce costs, and accelerate the market for electric vehicles. Therefore, through the safety evaluation of electric vehicles, especially the safety evaluation of batteries for electric vehicles, it is of great significance to closely control the quality of electric vehicles.
