Embodiment Construction

[0026] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0027] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0028] figure 1 is a flowchart of a parking method for a vehicle according to an embodiment of the present invention.

[0029] Such as figure 1 As shown, the parking method of a vehicle according to one embodiment of the present invention includes the following steps:

[0030] S1: Judging whether the current vehicle working condition satisfies the clearance automatic adjustment condition of the EPB execution unit.

[0031] In one embodiment of the present invention, the gap automatic adjustment conditions include the following conditions:

[0032] 1. The vehicle is in a stationary state for a first preset time, for example, 1 second;

[0033] 2. The engine is turned off for a second...

Abstract

The invention provides an electronic park brake (EPB) control method and control system and a vehicle. The method comprisesof determining whether the current vehicle operating condition meets an automatic clearance adjustment condition of an EPB execution unit; when the condition is met, controlling the EPB execution unit to perform braking, and obtaining the current brake clearance between the EPB execution unit and a brake disc; and adjusting the current brake clearance according to the standard brake clearance. The method can automatically adjust the distance between the EPB execution unitand the brake disc to ensure the brake effect of the EPB, thereby improving driving safety; the EPB execution unit is started for an emergency brake according to corresponding conditions, and in the emergency brake, the execution condition of the EPB execution unit is monitored, and the brake safetycan be improved; the EPB is subjected to fault detection and the result is displayed, so that a driveris assisted in understanding the fault condition of the EPB; and by setting an automatic park function, the phenomenon of sliding as an EPB switch is not started can be avoided.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a control method, a control system and a vehicle of an electronic parking system. Background technique [0002] Electrical Park Brake (EPB) replaces the electronic parking system button of the traditional lever handbrake, which is safer than the traditional lever handbrake, and will not change the braking effect due to the driver's strength, turning the traditional lever handbrake into a A button at your fingertips. However, if the braking effect of the electronic parking system is insufficient, it may threaten driving safety. Contents of the invention [0003] In view of this, the present invention aims to propose a control method for the electronic parking system, which can ensure the braking effect of the EPB, thereby improving driving safety. [0004] In order to achieve the above object, technical solution of the present invention is achieved in that way: [0005] A...
