Sensor for chassis control

Sensors for chassis control refer to sensors distributed in transmission control system, suspension control system, power steering system and anti-lock braking system. They have different functions in different systems, but their working principles are the same as those in engines. There are mainly the following types of sensors:

1. Transmission control sensor: mostly used for the control of electronically controlled automatic transmission. According to the information obtained from the detection of speed sensor, acceleration sensor, engine load sensor, engine speed sensor, water temperature sensor and oil temperature sensor, it makes the electronic control device control the shift point and lock the hydraulic torque converter, so as to achieve maximum power and maximum fuel economy.

2. Suspension system control sensors: mainly include speed sensor, throttle opening sensor, acceleration sensor, body height sensor, steering wheel angle sensor, etc. According to the detected information, the height of the vehicle is automatically adjusted, and the change of vehicle posture is suppressed, so as to control the comfort, handling stability and driving stability of the vehicle.

3. Power steering system sensor: It makes the power steering electronic control system realize light steering operation, improve response characteristics, reduce engine loss, increase output power and save fuel according to the speed sensor, engine speed sensor and torque sensor.

4. Anti-lock braking sensor: It detects the wheel speed according to the wheel angular velocity sensor, and controls the braking oil pressure to improve the braking performance when the slip rate of each wheel is 20%, so as to ensure the maneuverability and stability of the vehicle.

5. Temperature sensor: mainly detects engine temperature, intake gas temperature, cooling water temperature, fuel oil temperature, engine oil temperature, catalytic temperature, etc. The practical temperature sensors are mainly wire wound resistance, thermistor and thermocouple. Wire wound resistance temperature sensor has high accuracy, but poor response characteristics; Thermistor sensor has high sensitivity and good response characteristics, but poor linearity and low applicable temperature. Thermocouple type has high precision and wide temperature measuring range, but amplifier and cold end treatment should be considered.
