OF THE

SLIP RATE
When the brake pedal is pressed during driving, the wheels can lock before the vehicle comes to a stop. In such an
event, the maneuverability of the vehicle is reduced if the front wheels are locked, and the stability of the vehicle is
reduced if the rear wheels are locked, creating an extremely unstable condition. The ABS precisely controls the slip
rate of the wheels to ensure maximum grip force from the tires, thereby ensuring the maneuverability and stability of
the vehicle.
The ABS calculates the slip rate of the wheels based on the vehicle speed and the wheel speed, then it controls the
brake fluid pressure to reach the target slip rate.

SIGNAL
Wheel sensor
The wheel sensor outputs the speed signal to the ABS control unit
according to the pulser’s rotation speed.
ABS modulator-control
unit
ABS control unit
The ABS control unit processes the signal from the wheel sensor,
then outputs the ABS control signal to the modulator unit.
Modulator unit
The modulator unit receives the control signal, then controls brake
fluid pressure for each wheel.
Motor relay (inside of the ABS control unit)
The motor relay drives the ABS pump motor.
ABS fail-safe relay (inside of the ABS
control unit)
The ABS fail-safe relay cuts the power to the solenoid valve when
the problem is detected.
