Automotive engine, chassis, body control sensor inventory
With the development of electronic technology, the degree of electronicization of automobiles has been continuously improved, and the usual mechanical systems have been difficult to solve some problems related to the functional requirements of automobiles, and have been replaced by electronic control systems. The function of the sensor is to quantify the component that provides a useful electrical output signal according to the specified measured size, that is, the transducer that converts the physical and chemical quantities of light, time, electricity, temperature, pressure, and gas into signals. As a key component of the automotive electronic control system, the sensor directly affects the technical performance of the car. At present, there are about 10-20 sensors installed in ordinary cars, and there are more luxury limousines. These sensors are mainly distributed in engine control systems, chassis control systems and body control systems.
First, the engine control sensor
There are many types of sensors for engine control, including temperature sensors, pressure sensors, speed and angle sensors, flow sensors, position sensors, gas concentration sensors, knock sensors, and the like. These sensors are the core of the entire engine, which can improve engine power, reduce fuel consumption, reduce exhaust gas, reflect faults, etc. Because they work in harsh environments such as engine vibration, gasoline vapor,
