Abstract

The invention provides a method and a system for preventing abnormal application of vehicle parking brake. The system comprises a speed sensor, a pressure retaining valve, a parking brake cylinder anda parking brake control unit. After the parking brake control unit ECU detects that a vehicle is in a parking brake applying state, a running state of the vehicle is judged through speed informationobtained by the speed sensor, when the vehicle is in the running state, the parking brake control unit carries out staged control over the pressure retaining valve, and the pressure retaining valve enables the parking brake cylinder to exhaust air in a staged mode. According to the method and the system for preventing the abnormal application of the vehicle parking brake, the abnormal applicationof the parking brake can be detected in time, and operation danger of the vehicle caused by full input of a brake force is prevented through staged exhaust.

Description

technical field [0001] The invention relates to a method and a system for applying a braking force of a vehicle, in particular to a method and a system for preventing abnormal application of the parking brake of a vehicle by controlling the parking braking force. Background technique [0002] At present, in the field of public transportation, customers have higher and higher requirements for the safety and reliability of braking systems. Parking brake is a braking mode of the vehicle, which is mainly used for returning the vehicle to the warehouse or parking the vehicle for a long time. In the field of air brakes, there are two main types of vehicle parking brakes: electronic control and air control. Both the electronically controlled parking brake and the pneumatically controlled parking brake are realized by controlling the pressure of the parking brake cylinder. When the parking brake is applied, the pressure of the parking brake cylinder is exhausted through electric c...
