The invention discloses a dynamic adjusting method and device for automobile braking force and an automobile. The dynamic adjusting method comprises the steps that multiple pieces of brake pedal stroke data of the automobile and multiple pieces of deceleration data corresponding to the multiple pieces of brake pedal stroke data are obtained; formulating a relation table between brake pedal travel data and total target brake pressure according to the deceleration data; obtaining the total mass of the automobile and the estimated driving gradient of the automobile; correcting the total brake pressure according to the total mass, the estimated driving gradient and the deceleration data and generating a total target brake pressure; and according to the total target brake pressure, the front axle brake pressure, the rear axle brake pressure and the motor target brake torque of the automobile are determined. According to the dynamic adjustment method for the automobile braking force, dynamic adjustment of the braking force of the automobile under different loads and different slopes can be achieved, and the requirement for consistency of the braking force of a driver is met.
本发明公开了一种汽车制动力的动态调节方法、装置及车辆,包括:获取汽车的多个制动踏板行程数据和与多个制动踏板行程数据对应的多个减速度数据;根据减速度数据制定制动踏板行程数据和总目标制动压力的关系表;获取汽车的总质量和汽车的行驶估计坡度;根据总质量、行驶估计坡度和减速度数据修正总制动压力并生成总目标制动压力;根据总目标制动压力确定汽车的前轴制动器压力、后轴制动器压力和电机目标制动扭矩。本发明提供的汽车制动力的动态调节方法可以实现车辆在不同载荷下、不同坡度下制动力的动态调整,满足驾驶员制动感的一致性需求。
