BRAKE CONTROL SYSTEM


  1. CONSTRUCTION


    1. An active type speed sensor is used. This sensor contains a Hall IC.

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

    3. An active type speed sensor uses a Hall 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.

    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 vehicle speeds even when the vehicle is nearly stationary.
