BRAKE CONTROL SYSTEM DETAILS SPEED SENSOR

  1. SYSTEM CONTROL

    1. An active type speed sensor is used.

    2. The speed sensors use a magnet type sensor rotor, which consists of N and S poles that are arranged in a circle. The speed sensor rotor is integrated into the hub bearing inner race.

    3. The active type speed sensor uses a sensor IC to detect magnetic field changes caused when the sensor rotor rotates, and the sensor outputs the detected information to the skid control ECU as digital pulses (vehicle speed signal).

    4. To detect the vehicle speed, the frequency of the output pulses is used. Because the active type sensor outputs digital pulses, it can detect the vehicle speed even when the vehicle is nearly stationary.
