Classification and function of all sensors on the vehicle:

1. According to the physical quantities of sensors, it can be divided into sensors such as displacement, force, speed, temperature, flow and gas composition;

2. According to the working principle of sensors, it can be divided into sensors such as resistance, capacitance, inductance, voltage, Hall, photoelectric, grating and thermocouple.

3. According to the nature of the output signal of the sensor, it can be divided into: the switch-type sensor whose output is switching value ("1" and "0" or "on" and "off"); The output is an analog sensor; Digital sensor whose output is pulse or code.

4. According to the functions of sensors in automobiles, they can be classified as temperature sensor, pressure sensor, flow sensor, position sensor, gas concentration sensor, automobile speed sensor, brightness sensor, humidity sensor, distance sensor, etc. They all perform their respective duties. Once a sensor fails, the corresponding device will not work normally or even. Therefore, the role of automobile sensors is very important.

Automobile sensors at different positions of the automobile, such as transmission, steering gear, suspension and ABS:

Transmission: there are speed sensors, temperature sensors, shaft speed sensors, pressure sensors, etc., and steering devices are angle sensors, torque sensors and hydraulic sensors;

Suspension: speed sensor, acceleration sensor, body height sensor, roll angle sensor, angle sensor, etc.

Automobile intake pressure sensor;

The automobile intake pressure sensor reflects the change of absolute pressure in the intake manifold, and provides the ECU (engine electronic control unit) with a reference signal for calculating the fuel injection duration. It can measure the absolute pressure in the intake manifold according to the load state of the engine, and convert it into an electrical signal and send it to the computer together with the rotational speed signal as the basis for determining the basic fuel injection quantity of the injector. At present, the semiconductor varistor type intake pressure sensor is widely used.
