ABS Wheel Speed Sensor, 89546-0K240 Wheel Speed Sensor For Toyota Revo 4WD
Car speed sensor function editing
1. Detecting the driving speed of the car, and inputting the detection result to the automobile instrument system for displaying the vehicle speed;
2. Input the detected vehicle speed signal to the ecu of the vehicle control system that requires the vehicle speed signal;
3. Used in automatic transmission system, cruise fixed speed system;
The performance of the abs differs depending on the control path. In general, it can be divided into: Mode 1: 4 sensor 4 channel mode 2: 3 sensor 3 channel mode 3: 4 sensor 3 channel mode 4: 4 sensor 2 channel mode 5: 2 sensor 2 channel mode 6: single sensor single channel The most common ones are mode 1 and mode 3. The control method of abs is electro-hydraulic control. That is to say, using a computer to control each solenoid valve to achieve the purpose of controlling the hydraulic oil circuit. The overall control mechanism is the abs computer. The computer collects information on the wheel speed detected by the sensors on the four wheels for analysis.
