The invention provides an electronic parking brake running-in device, a running-in method, an electronic parking system and a corresponding vehicle. The running-in device comprises a running-in instruction input module for inputting a running-in instruction and a running-in parameter, and a network interface module for being connected and communicated with an electronic control unit and sending the running-in instruction and the running-in parameter to the electronic control unit, wherein the electronic control unit is used for controlling a parking brake to generate corresponding electronic parking tension according to the running-in instruction and the running-in parameter, so that running-in can be realized on the parking brake under a condition of vehicle running. The electronic parking system comprises the electronic control unit, an executor and the parking brake which are connected with one another in sequence; the electronic control unit is configured to receive the running-in instruction and the running-in parameter and control the executor and the parking brake to generate the corresponding electronic parking tension, so that the running-in can be realized on the parking brake under the condition of vehicle running. The electronic parking brake running-in device, the running-in method, the electronic parking system and the corresponding vehicle can precisely control a running-in process and flexibly adapt to a running-in place.
Description
technical field [0001] The invention relates to the technical field of automotive electronics, in particular to an electronic parking brake running-in device, a running-in method, an electronic parking system and a corresponding vehicle. Background technique [0002] Due to the installation characteristics of the brake friction plate, the joint area of the newly installed brake friction plate cannot meet the standard, resulting in low friction efficiency in the initial state, which may not meet the design requirements. Because the service brake can be operated by stepping on the brakes during driving, the friction efficiency will continue to increase due to the dynamic running-in of the wheels and the friction of the friction plates during driving. However, the parking brake usually only works under static conditions, and the number of times of work is much less than that of the service brake. The initial friction efficiency is low. The parking brake must be worn in. [...
