The automotive environment is so harsh, and the silicon chip is so sensitive to various interferences, ambient temperature and power supply, it is easy to cause operational errors. Most car users believe that the current electronic power system is still very immature and is far less safe and reliable than the mechanical power transmission system. Some people who prefer driving pleasure even believe that the electronicization of powertrain systems will cause people to lose the opportunity to enjoy driving pleasure.
The increase in people's requirements for safer driving has prompted cars to start planning safety control systems from a system perspective. Therefore, the current body safety control system is no longer just a simple reversing radar, distance detection and airbag control, but has added many new elements.
The emerging intelligent body control system can obtain environmental information around the car through various sensor devices, such as road obstacles and curve warnings, so that drivers and passengers can understand the environment around the car in a timely manner. More importantly, these body control systems can also collect information about the car itself, such as tire pressure, etc., and can be adjusted through the power control system to keep the car in a stable driving state. In addition, various anti-collision sensing systems are also under development. After obtaining the early warning information through the sensor device, the control system will immediately trigger the protection system to reduce the impact of the driver and passengers. Moreover, the latest intelligent airbag control system can also quickly adjust the degree of inflation of the airbag through the collected impact force.
Automotive Infotainment System
As the concept of entertainment driving is deeply rooted in people's hearts, the multimedia functions integrated in cars are becoming increasingly powerful. Car entertainment is not just as simple as car audio. The continuous introduction of navigation and positioning, wireless mobile communications, network data transmission and anti-theft security functions has gradually turned cars into mobile offices or mobile homes. Due to the need to transmit and process large amounts of data in real time, vehicle information processing systems have become increasingly prominent. Market research company Dq has predicted that the market, including hardware and services, will grow from US$100 million per year to US$100 million per year, with a compound annual growth rate of %. As a result,
manufacturers of communication systems, computer systems and consumer electronics all regard automobiles as the next potential growth market. Not only that, various emerging business models will also serve as natural carriers. For example, D, launched by Company B for car manufacturers, car rental companies and insurance companies, uses the company's car customer architecture to enable wireless connections with open standard applications such as and .
Remote car diagnostic system
In addition, the complexity of automotive electronic systems has led to more and more signals displaying vehicle condition information in the car. Ordinary car users may be at a loss for the displayed faults. Remote vehicle diagnostic system (RD) emerged as the times require. In fact, the current remote car diagnostic system is an extension of the application, because it mainly sends the fault codes generated by the electronic control module diagnosis to the nearest analysis center of the car manufacturer through wireless communication technology. Not only that, this system also sends the identity of the car and its geographical location through the vehicle. However, security issues are the main obstacle preventing large-scale application of remote vehicle diagnostic systems. Car users are worried that the data packet information containing the car's identity and geographical location will be intercepted by others or controlled by the car. Automobiles, too, worry that the public will know too much about the cars' potential flaws. However, once safety is guaranteed, this business model should have broad market space. For example, car dealers can use the system to enhance service to customers. Because fault codes are automatically transmitted to the dealer, service technicians can immediately determine the severity of the problem and contact the owner directly to arrange service or alert the user to potential mechanical problems. And in the future, cars can also use this system to understand the driving habits of car users to create cars that are more suitable for driving.
Automotive power supply system
The increasing use of electronic devices in automobiles has increased the demand for electricity and power in automobiles, and the original power supply system has been unable to meet its requirements. The system has already become the focus of the industry because it has many features that are superior to the system. But the difficulties encountered in implementing the system are also obvious. First of all, this requires the efforts of the entire automotive industry, because most automotive components are designed for systems and cannot work properly without calibration or some kind of control circuit, so various measures must be taken to make them adapt to high temperatures. Voltage. Secondly, the power distribution of the entire automotive electronic system also needs to be redesigned and planned. Because the increase in voltage requires more voltage conversion devices and circuits, the demand for protection circuits will also increase, which will increase the complexity and design difficulty of the entire power supply system. In the transition period to the system, major car manufacturers have chosen to adopt dual-voltage systems. At least for now, system performance seems to be stretched beyond what was predicted years ago, and there are no clear signs of when high-power applications will come to an end or when applications will begin to be widely accepted.
