ESP® control module/ hydraulic unit
The control module receives signals from each wheel speed sensor, ESP OFF switch, brake master cylinder pressure
sensor, steering angle sensor and yaw rate / G sensor. Based on these signals as information, the control module
judges the vehicle conditions and controls the brake hydraulic pressure by combining the ON/OFF operation of the
solenoid in the hydraulic unit and the pump motor operation.
The hydraulic unit contains an inlet solenoid valve and an outlet solenoid valve for each wheel as well as a cut
solenoid valve and a low pressure solenoid valve for each hydraulic unit system. Also, a master cylinder pressure
sensor, pump motor, etc. are included. The hydraulic pressure control is done in 3 modes of pressure increase,
pressure keeping and pressure reduction.
