Embodiment Construction

[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] Embodiment of the vehicle parking brake control method:

[0025] This embodiment provides a vehicle parking brake control method, by detecting the state parameters of the vehicle, and by defining the brake pedal opening size under different working conditions to define whether the parking brake function is triggered, to meet the driver's needs Personalized requirements can meet the control requirements under different working conditions, and improve the control flexibility of the parking automatic braking function.

[0026] In order to realize the above vehicle parking brake control method, a parking brake system is adopted, and the structural principle diagram of the system is shown in figure 1 As shown, it includes a vehicle cont...

Abstract

The present invention relates to a vehicle parking brake control method and device. The method includes: judging whether the conditions for automatically opening the parking brake are met, and the conditions for automatically opening the parking brake at least include: the actual speed of the vehicle is reduced to a set speed threshold; Parking brake automatic opening condition, judging whether the current brake pedal opening is greater than the first set brake pedal opening threshold; if the current brake pedal opening is greater than the first set brake pedal opening threshold, the control system If the opening of the pedal increases, a stop automatic braking start command is issued, and the parking automatic braking function is turned on. In the present invention, the driver can independently choose whether to activate the parking automatic braking function by controlling the opening of the brake pedal, fully considering the driver's individual needs, and the control is simple, convenient and flexible.

Description

technical field [0001] The invention relates to a vehicle parking brake control method and device, belonging to the technical field of vehicle brakes. Background technique [0002] During the driving process, drivers often encounter working conditions such as waiting for red lights, congestion, and pit stops, and need to stop temporarily. In the process of temporary parking, in order to avoid slipping, the driver will always step on the brake or pull on the handbrake. In order to reduce the labor intensity of the driver's operation during the temporary parking process, some vehicles currently have the parking automatic braking function. [0003] The opening of the existing parking automatic braking function generally requires the driver to realize by pressing a function key (such as the AutoHold button), or when the vehicle speed is lower than a certain value, the parking automatic braking function is automatically turned on. When the automatic parking braking function is ...
