Design of a Cable Pulled Electric Parking Brake System for Light Commercial Vehicle

In order to solve the insufficient parking brake force and other problems of mechanical parking brake system in light commercial vehicle, a cable pulled electric parking brake system had been designed. The hardware and the control strategy of the system had been put forward; In order to verify the feasibility and reliability of cable pulled electric parking brake system, the modeling and simulation of mechanical and electrical parts were completed with MATLAB/Simulink. The simulation results show that the designed maximum braking torque is 5107.38 Nm, which meets the national related standard for parking brake system. The whole parking brake process only takes 1064.1 ms, it is very fast. This design makes parking brake system more intelligent, improves the safety and comfort of light commercial vehicle.
