Embodiment Construction

[0025] In order to describe the technical content of the present invention more clearly, further description will be given below in conjunction with specific embodiments.

[0026] The present invention is made up of parking switch, ECU (Electronic Control Unit), EPB actuator and double-piston caliper, EPB actuator 1 is fixed on double-piston caliper 2, and the piston movement in double-piston caliper 2 is driven by EPB actuator 1 , so that the brake pad 3 is displaced, and the brake disc 4 is clamped or loosened, thereby realizing the parking and parking release functions.

[0027] In the present invention, ECU receives and judges signals from EPB switch, engine, safety belt, brake and car door, and then controls the current direction and magnitude leading to the motor in the EPB actuator.

[0028] The invention controls the forward rotation and reverse rotation of the motor by controlling the current direction leading to the motor in the EPB actuator. When the motor rotates ...

Abstract

The invention relates to an electronic parking braking system with double-piston calipers. The electronic parking braking system comprises an EPB actuator and the double-piston calipers, and the EPB actuator is used for driving the double-piston calipers. The system further comprises an electronic control unit used for controlling the current direction and intensity of a motor in the EPB actuator. The electronic parking braking system which is of the structure and is provided with the double-piston calipers is adopted, as the calipers used are double-piston calipers and are different from single-piston calipers used in the current market, the double-piston calipers can provide larger brake force in the same hydraulic system, and therefore the double-piston calipers are used in medium and large vehicles and other vehicles high in requirement for brake performance more frequently. By means of the provided EPB actuator and the double-piston caliper parking mode, the application field and range of novel EPB are enlarged.

Description

technical field [0001] The invention relates to the technical field of electronic parking, in particular to the technical field of calipers of a dual-piston electronic parking system, in particular to an electronic parking brake system with dual-piston calipers. Background technique [0002] With the continuous development and progress of science and technology, people's requirements for automobile safety are increasing day by day, and excellent braking performance and integrated chassis comprehensive control technology are an important evaluation symbol of modern automobile safety. With the development of electromechanical technology, electronic technology continues to penetrate into the automotive braking system, and the automotive electronic parking brake system (EPB: Electronic Parking Brake) has emerged. The electronic parking brake system is driven by a motor that uses both mechanical transmission and electronic control to implement parking brakes. Features. At prese...
