Electrical technology is the core of automobile industry, and the level of which determines the intelligent levels of cars directly.Sensors are the key components to achieve automatic control and detection of intelligent vehicles, an ordinary car is installed with about hundreds of sensors, while the number of sensors installed in luxury cars may be as high as more than 200.
Smart sensors are an integrated technology that is not only a sensor device, but is a sensor with analog converter, signal processor, CPU and smart meter combination.It uses various network communication protocols to enable multiple device groups to work better with other electronic devices, thus interconnection between components is achieved, ensuring intelligent and effective detection of information by sensors.
The application of smart sensors in smart cars is mainly to detect, collect and process the information emitted by the engine and measure the parameter values of each system during the operation of the car, so that the driver can keep track of the operation of the car.In smart cars, the biggest advantage of smart sensors is that they can fully sense the passenger situation, surrounding environment and traffic facilities and other information, and then determine whether the passengers are in the best condition, whether the vehicle will be in danger, etc., and take corresponding measures in time.
In smart cars, the engine is the core component with the most sensors. Not only gas density sensors, position sensors, pressure sensors, but also temperature sensors, vibration sensors and flow sensors. These sensors can provide operating information for the engine system, so that the controller can real-time.These sensors provide the engine system with operating information that allows the controller to understand and control the engine's operation in real time to achieve optimal power performance, reduce vehicle emissions, and achieve optimal fuel economy.
In the chassis control system of intelligent vehicles, there are more types of sensors, and the main systems applied include brake anti-lock system, power steering system and suspension.The main systems used include brake anti-lock system, power steering system and suspension control system. Although the sensors are distributed in different parts of the chassis control system, but the working principle of sensors is the same as that of engine sensors. In the automotive chassis control system, the most important one is the anti-lock system, which uses the brake pressure automatic. The most important part of the chassis control system is the anti-lock system, which uses the automatic brake pressure adjustment device to realize the vehicle braking treatment.
With the continuous development of electronic control systems, unified sensors sensors have emerged and are widely used, which can provide signals not only to the engine system to the engine system, but also to the chassis control system, thereby improving the This sensor not only provides signals to the engine system, but also to the chassis control system, thus improving the stability of the vehicle.
In the electronic system of smart cars, sensor plays an important role, which is mainly used in the chassis control system, engine control system and navigation system. It can not only increases the safety of driving, but also improves the driving experience of users. Based on this, the car manufacturers promote the intelligence level of the cars they produced by optimizing the performances of sensors, whereby winning more consumers' favor in the fierce market competition.
