Electric parking brakes

Solutions for Passenger Cars


Control Unit

The electric parking brake replaces the conventional handbrake lever within the interior by a switch or push button. The Electric Parking Brake control unit (EPB-ECU) provides a fully automated control of different types of EPB actuators e.g. caliper integrated actuators or cable pullers. The EPB-ECU controls the actuator and provides smart functionality, recognizing when to apply and release the parking brake. To do this, the EPB-ECU is fully integrated into the vehicle’s network architecture. The EPB-ECU evaluates data from various engine, transmission, and wheel sensors, as well as tracking the position of the clutch and throttle.
