System Description

SENSOR
NCBR0087S01
The sensor unit consists of a gear-shaped sensor rotor and a sen-
sor element. The element contains a bar magnet around which a
coil is wound. The sensor is installed on the back side of the brake
rotor. Sine-wave current is generated by the sensor as the wheel
rotates. The frequency and voltage increase(s) as the rotating
speed increases.

CONTROL UNIT
NCBR0087S02
The control unit computes the wheel rotating speed by the signal
current sent from the sensor. Then it supplies a DC current to the
actuator solenoid valve. It also controls ON-OFF operation of the
valve relay and motor relay. If any electrical malfunction should be
detected in the system, the control unit causes the warning lamp
to light up. In this condition, the ABS will be deactivated by the
control unit, and the vehicle’s brake system reverts to normal
operation.
