Body perception sensors are all over the body of the car, and are widely used in the power system (new energy vehicles are three-electric systems), chassis systems, and body systems to realize the perception of the car’s own information and make decisions and executions. It is the “nerve end” of the car. At present, the development is relatively mature, mainly based on MEMS sensors. The source of power is one of the main differences between new energy vehicles and traditional fuel vehicles. The electrical and electronic architecture of new energy vehicles mainly uses current-based electromagnetic sensors related to batteries, motors, and electronic controls. The power system of fuel vehicles mainly uses measurement Pressure, temperature, and gas sensors are the main ones; the demand for electromagnetic sensors is expected to gradually increase with the increase in the penetration rate of new energy vehicles. According to the different physical quantities to be measured, the body perception sensors can be divided into various types of sensors such as pressure, position, temperature, acceleration, gas, and flow.
