BRAKE CONTROL SYSTEM


  1. CONSTRUCTION


    1. Active type speed sensors that can measure down to a very low speed are used.

    2. The front speed sensors are installed to the steering knuckle. The front speed sensors use a magnetic sensor rotor which consists of N and S poles that are arranged in a circle. The rotors of the front speed sensors are mounted to the inner race of the front axle hub and bearing assemblies.

    3. The rear speed sensors are installed to the rear axle carrier sub-assembly. The rear speed sensors use a magnetic sensor rotor which consists of N and S poles that are arranged in a circle. The rear speed sensor rotors are mounted to the inner race of the rear axle hub and bearing assemblies.

    4. System Control


      1. The magnetic rotor consists of 48 ferrite powder magnets embedded around its circumference.

      2. The active type speed sensor uses a sensor IC to detect the changes in the magnetic field as the sensor rotor rotates, and outputs a pulse signal representing the rotational speed of the wheel.

      3. The frequency of the pulses is used to determine the speed of the vehicle and detection down to almost 0 km/h is possible.
