A new design of integrated Electric Parking Brake system, called iEPB and integrated in the brake caliper, is introduced in this paper. It consists of an electrically operated brake unit and a hydraulically pressed unit independently, and uses a special self-locking mechanism instead of a screw device to increase the efficiency and the working speed. With all conventional EPB system's advantages, it also provides a stronger brake performance and a faster reaction time. In this paper, we describe the working principle of this new design at first, and then introduce the arrangement of the testing system, followed by a discussion of experimental data. The testing results prove the feasibility of this design. The conclusion paragraph summarizes the key points about the design of the iEPB system.

Electric parking brake (EPB) system provides the roomy space for vehicles compared with traditional handbrake system. Combining a control unit realizes the intelligent functions, which make vehicles more convenient and secure, and avoid the vehicle damage and danger caused by the negligence of drivers. This paper provides a new concept design of the EPB system that has simple and low-cost characteristics. The testing results have proved the feasibility of this design. First we describe the working principle of this new design, and then introduce the arrangement of the testing system, followed by the discussion of experimental data. The last is conclusion paragraph.
