Description

The electronic parking brake (EPB) is different from existing parking systems which operated with the brake pedal or the lever type. The EPB system sends the signal to the ECU when a driver operates the EPB switch. The ECU operates the EPB actuator composed with motor gears. The braking power is caused by occurs when the motor pulls the cable connected the brake system.

The EPB ECU is one of the parts of EPB system. It perceives the signal of the various sensor of system, executes a self diagnosis, controls EPB system with the logic.
