Embodiment Construction

[0037] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0038] like figure 1 As shown, in a first aspect of the present invention, a vehicle electronic parking control method is provided, including:

[0039] Responding to the request signal, acquiring the gear position signal and operating parameters of the vehicle;

[0040] When the gear position signal is the parking gear signal, and the vehicle running state is judged to be the first parking state according to the operating parameters within the preset delay time, the electronic parking actuator is controlled to output the first braking force so that the wheels are not electronically parked. The car actuator is locked.

[0041] In this way, this embodiment trig...

Abstract

The embodiment of the invention provides a vehicle electronic parking control method and device, a system and an automobile, and relates to the technical field of automobile brake control. The method comprises the steps that in response to a request signal, a gear signal and operation parameters of the automobile are obtained; and when the gear signal is a parking gear signal and the running state of the vehicle is judged to be a first parking state according to the running parameters within the preset time delay, the electronic parking executing mechanism is controlled to output first braking force, so that wheels are not locked by the electronic parking executing mechanism. When it is judged that the running state of the vehicle is the predetermined first parking state according to the gear signal and the running parameters of the vehicle, the electronic parking executing mechanism is controlled to output the first braking force so that a brake friction plate and a brake disc can not be pressed tightly; the situation that the friction plate and the brake disc cannot be normally separated due to long-time compression in rainy days or low-temperature weather is avoided, and meanwhile the static state of a vehicle can be kept through parking of a parking gear.

Description

technical field [0001] The invention relates to the technical field of automobile brake control, in particular to a vehicle electronic parking control method, a vehicle electronic parking control device, a vehicle electronic parking control system and an automobile. Background technique [0002] Automotive Electronic Parking Brake (Electrical Parking Brake, referred to as: EPB) refers to the technology of electronically controlled parking brake, which replaces the traditional manual pull-wire parking brake system, which simplifies the user's operation and improves The user comfort and convenience are improved, but the parking braking force (the pressing force between the brake friction plate and the brake disc) cannot be adjusted, and the user cannot independently choose the parking braking force according to the environment and usage conditions. At the same time, the automatic parking strategy of the existing automotive electronic parking system does not have a parking func...
