Problems solved by technology

When starting on a relatively large slope, since the coordination between the timing of the release of the parking force and the depth of the accelerator pedal is controlled by the driver based on experience, the parking force is too small when the driving force is insufficient. Car slipping, even causing the risk of t

Abstract

The invention discloses a parking brake control system and method for a vehicle, and the vehicle. The system includes: at least one electronic parking caliper for braking the wheels of the vehicle; an electronic parking switch for Receive the parking command from the driver; the communication network connected with the engine system, gearbox system, and body control system is used to obtain engine status signals, gearbox gear signals, ignition switch status signals and brake pedal signals; electronic parking The control device is used to obtain the driver's parking intention according to the engine state signal, the gearbox gear signal, the ignition switch state signal and the brake pedal signal, and to control the driver's parking intention according to the driver's parking intention. The electronic parking caliper is controlled, or the electronic parking caliper is controlled according to the parking command. The system of the embodiment of the present invention reduces the cost while realizing the weight reduction of the whole vehicle, and reduces the risk of accidental damage to the gearbox.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a parking brake control system and method for vehicles and the vehicle. Background technique [0002] At present, the parking brake control system of motor vehicles, especially the parking brake control system and control method applied to vehicles with automatic transmission, has attracted more and more attention from automobile manufacturers and consumers. For vehicles with automatic transmission, there will be a P gear locking mechanism inside the automatic transmission, which can lock the output shaft of the transmission to prevent the rolling of the driving wheels; Safe parking without affecting the use of the gearbox. In addition, a set of parking mechanism is set up for parking, which is generally a traditional mechanical parking brake system (for example: parking handle or parking pedal). [0003] At present, the parking brake mechanism applied to the automatic transmission, when...
