Parking brake control system, method and vehicle for vehicle

Abstract

The invention discloses a vehicle parking braking control system, method and a vehicle; the vehicle parking braking control system comprises the following structures: at least one electronic parking caliber used for parking vehicle wheels; an electronic parking switch used for receiving a driver parking order; a communication network connected with an engine system, a gearbox system and a vehicle body control system so as to obtain an engine status signal, a gearbox shift signal, an ignition switch status signal and a brake pedal signal; an electronic parking controller used for obtaining driver parking intention according to the engine status signal, the gearbox shift signal, the ignition switch status signal and the brake pedal signal, and used for controlling the electronic parking caliber according to the driver parking intention, or controlling the electronic parking caliber according to the parking order. The vehicle parking braking control system can reduce cost, can realize vehicle lightweighting, and can reduce gearbox accident damage risks.

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...

AI Technical Summary

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 traffic accidents

In the case of a rear-end collision accident in the P gear parking state, it is very likely to cause damage to the gearbox and cause high losses to the user

In addition, this kind of parking brake control system that requires two sets of parking brake mechanisms has redundant hardware devices and high cost
