The invention relates to a parking brake control method and system and a motor vehicle, and aims to solve the problems that the vehicle slips when starting on a slope, is dragged and rushes on a flat road and the like by performing combined control on an execution module of an electronic parking system and a motor torque through a whole vehicle controller. When the parking or temporary parking function of the electronic parking system is released, the real-time change of the gear of the whole vehicle and the rotating speed of the motor is monitored to execute different motor torque rise gradient logics, so that the safety of hill starting is ensured, and the comfort of flat road starting can also be ensured.
本发明涉及驻车制动控制方法、系统及机动车辆,通过整车控制器对电子驻车系统的执行模块与电机扭矩进行联合控制,以解决车辆坡道起步溜坡和平路拖滞、发闯等问题。电子驻车系统的驻车或临停功能释放时,监测整车档位与电机转速的实时变化来执行不同的电机增扭梯度逻辑,既保证坡道起步的安全性,又能确保平路起步的舒适性。
