The embodiment of the invention provides a method for reducing jittering during starting of an automatic parking keeping function of a vehicle, and the method comprises the steps: obtaining the mass of the vehicle and the road information of a road where the vehicle is located at present, and calculating an initial driving torque which should be output when the vehicle enters a driving state from a parking state based on the mass of the vehicle and the road information; driver interaction information, vehicle dynamic information and a vehicle braking force calculation mode of an AVH state machine in an AVH release state are obtained, and initial braking force needing to be released and a pressure release strategy needing to be adopted in the AVH release state of the vehicle are calculated; when the current state of the AVH state machine is an AVH release state, the braking force is released according to the calculated initial braking force by adopting a pressure release strategy, and the initial driving torque of the vehicle is output according to the calculated initial driving torque. And the user experience is improved.
本申请实施例提供一种用于车辆自动保持驻车功能启动时减少抖动的方法,该方法包括:获取车辆的质量以及车辆当前所在道路的道路信息,基于车辆的质量以及道路信息计算出车辆由驻车状态进入驱动状态时应输出的初始驱动扭矩;获取驾驶员交互信息、车辆动态信息以及AVH状态机在AVH释放状态下车辆的制动力计算方式,计算出车辆在AVH释放状态下应释放的初始制动力以及应采取的压力释放策略;当AVH状态机当前所处的状态为AVH释放状态时,按照计算出的初始制动力以及采用压力释放策略释放制动力,并按照计算出的初始驱动扭矩输出车辆初始的驱动扭矩,本申请实施例能够避免车辆停止后自动保持制动状态再起步时产生抖动,从而提高用户体验。
