To meet increasing requirements in regard of safety, comfort and networking the electric parking brake is progressively replacing the mechanical hand brakes. The EPB based on drum brakes is ideal for use in electric vehicles. In addition to the improved safety and comfort for the customers it offers the car manufacturers more freedom and options for the vehicle interior design and driver assistance systems installation.
The Electric Parking Brake in general replaces the mechanical activation via the hand brake lever by an electrical switch and electromechanical actuators building up the required clamp forces.
The EPB-Si is a mainstream industry product within the portfolio of EPB solutions being developed by Continental and is a great solution for electric vehicles. Electromechanical actuators are mounted directly to the rear axle drum brakes to achieve the brake torque and can be controlled by devices from the caliper integrated systems that are also offered by us. The reliability and performance of the EPB-Si avoids the need for a separate park gear lock. Furthermore, its proven low residual torque contributes to a higher range in electric vehicles. The encapsulated design of the EPB-Si unit results in low levels of corrosion when compared to conventional brakes, while maintaining low degrees of emission particles.
