Problems solved by technology

At present, the vast majority of domestic vehicle parking brake devices use hand brake devices, and there are many shortcomings in the hand brake device. Space, when the car starts on a slope, the operation is too complicated, and it is difficult for some novices to control it, which will cause the car to slide down the slope; in addition, during the long-term use of the hand brake device, it is easy to cause mechanical damage to the steel cable in the brake zipper. Deformation, the braking device may therefore be difficult to obtain enough braking force for safe parking, which poses a safety hazard; and when the handbrake is applied, the driver is used to applying the maximum braking force no matter what parking situation to ensure safety Parking, which causes a lot of wear and tear on the mechanical parts

Abstract

The invention discloses a vehicle parking braking system, which comprises a signal acquisition unit for acquiring a vehicle state signal and a signal input unit for inputting a driver operation instruction, wherein the signal acquisition unit and the signal input unit output signals to a control unit; the control unit analyzes and processes the signals, and controls an execution unit to enable a vehicle brake caliper to clamp or release a brake disc. According to the system, required optimal braking force can be provided for parking, and the mechanical abrasion of the brake caliper is effectively reduced; in addition, the system can function in emergency braking after a travel braking system fails, so that a vehicle can be safety parked, and the safety of the vehicle is ensured.

Description

technical field [0001] The invention relates to the field of vehicle control systems, in particular to a vehicle parking brake system and a control method thereof. Background technique [0002] The car brake system includes a service brake system and a parking brake system. The service brake system is called a foot brake; the parking brake system is called a hand brake. The traditional parking brake system device generally includes three parts: hand brake control, transmission and brake, which belong to purely mechanical operation. At present, the vast majority of domestic vehicle parking brake devices use hand brake devices, and there are many shortcomings in the hand brake device. Space, when the car starts on a slope, the operation is too complicated, and it is difficult for some novices to control it, which will cause the car to slide down the slope; in addition, during the long-term use of the hand brake device, it is easy to cause mechanical damage to the steel cable ...
