Detailed classification and function of automotive sensors

04

Steering wheel angle sensor

It is mainly installed in the vehicle's electronic steering system to detect the steering wheel angle and convert the change into an electrical signal, which is then provided to the steering ECU to calculate the degree of inclination of the vehicle body.

05

Torque Sensor

It is mainly installed in the vehicle's electronic steering system to detect the steering load torque signal of the steering wheel, convert the change into an electrical signal, and provide it to the steering ECU.

06

Yaw rate sensor

It is used to detect and record the movement of the car around the vertical axis, and after converting the change into an electrical signal, it is provided to the steering ECU to determine whether the car is slipping.

07

Lateral angular velocity sensor

It is used to detect the eccentricity generated when the car turns, and convert the change into an electrical signal, which is then provided to the steering ECU to determine whether the car slips when passing through a curve.

Other Sensors

01

Oil quality sensor

Ceramic capacitors are used to detect the stability of the engine oil medium to remind you to change the engine oil in time, reduce engine wear and extend its service life.

02

Power seat sensor

Usually installed around the bottom of the seat, it is used to provide the front and back, height and low signals of the seat to the seat electronic control system to automatically adjust the seat position and has a memory function. It is generally composed of 4 sensors, including a sliding position sensor, a front vertical position sensor, a rear vertical position sensor and a tilt position sensor.

03

Headlamp high and low beam control sensor

It is used to sense the light intensity of the oncoming vehicle when cars meet at night, and after converting the change into an electrical signal, it is provided to the electronic control system of the headlight so that the light can be changed in time to prevent glare.

04

Fingerprint sensor

It is mainly used in the car's security and anti-theft system to identify legal drivers, with a detection error rate of less than 0.01%.
