Parking braking system applied to motor vehicle

Abstract

The invention discloses a parking braking system. The system comprises a controller, an electromechanical actuator and the like. The electromechanical actuator comprises a motor, a reduction gear system, a brake caliper assembly and the like; the electronic controller consists of a power supply and a plurality of modules connected with the power supply; the plurality of modules comprise a main control module, wherein the main control module is connected with the other modules through circuits and realizes the control and the communication with each module. Technical problems of drifting phenomenon, insufficient braking force caused under a special working condition, hidden troubles existing in the aspects of safety and comfort and the like in a vehicle can be solved. Simultaneously, the system has the advantages of independent modules, more reliable overall performance, system safety, more compact structure, high integration level and easier system miniaturization.

Description

technical field [0001] The invention belongs to the technical field of motor vehicle brake systems, and in particular relates to an electronic parking brake system applied to motor vehicles. Background technique [0002] In the field of motor vehicle brake system manufacturing technology, the parking brake system is widely used in various vehicles. As an important auxiliary system on the motor vehicle, it has the function of providing parking brake force and auxiliary braking. [0003] At present, most of the parking brake systems applied to motor vehicles are parking brake systems of traditional structure. The traditional structure of the parking brake system is a mechanical manual parking system. The parking brake handle drives the mechanical cable, and then the mechanical cable drives the brake caliper or brake disc installed on the wheel hub to perform related operations to realize the parking brake. However, the traditional structure of the parking brake control system...

Problems solved by technology

[0006] The technical problem to be solved by the technical solution provided by the present invention is that because the existing parking brake system adopts a traditional structure, it cannot independently control the braking force between the left and right wheels in time, and tail flicking is prone to occur at high speeds, so it is necessary to increase the parking brake system. When the braking force of the car is used, the braking force is insufficient under special working conditions, and there are technical problems such as hidden dangers in terms of safety and comfort, and an electronic parking brake system controller is provided.
