The embodiment of the invention relates to a processing method for controlling the braking percentage. The method comprises the steps that the planned speed, the planned acceleration, the controlled acceleration, the pitch angle, the real-time vehicle speed and a driving gear mark are obtained; performing uphill and downhill acceleration recognition according to the pitch angle; determining whether to enter a parking mode according to the driving gear mark, the planned acceleration, the planned speed and the real-time vehicle speed; if it is confirmed that the vehicle enters the parking mode, target acceleration recognition of the parking mode is conducted according to the driving gear mark, the real-time vehicle speed and the uphill and downhill acceleration; if it is confirmed that the vehicle does not enter the parking mode, target acceleration recognition in a non-parking mode is carried out according to the control acceleration and the uphill and downhill acceleration; and inquiring the first corresponding relation table according to the real-time vehicle speed and the target acceleration to obtain the braking percentage. According to the invention, the braking process can be divided into two stages of high-speed slow braking and low-speed heavy braking, so that the somatosensory comfort of passengers is improved; and the vehicle sliding on the slope can be prevented through the acceleration compensation of the uphill and downhill acceleration.
本发明实施例涉及一种控制刹车百分比的处理方法,所述方法包括:获取规划速度、规划加速度、控制加速度、俯仰角、实时车速和行车档位标记;根据俯仰角进行上下坡加速度识别;根据行车档位标记、规划加速度、规划速度和实时车速确认是否进入停车模式;若确认进入停车模式,则根据行车档位标记、实时车速和上下坡加速度进行停车模式的目标加速度识别;若确认未进入停车模式,则根据控制加速度和上下坡加速度进行非停车模式的目标加速度识别;根据实时车速和目标加速度查询第一对应关系表获得刹车百分比。通过本发明,可将刹车过程分为高速缓刹和低速重刹两个阶段,提高乘客体感舒适性;可通过上下坡加速度的加速度补偿防止出现坡上溜车。
