The invention provides a vehicle braking method and system, and the method comprises the steps: determining the actual variable quantity of the torque of each brake wheel according to the target braking torque corresponding to each brake wheel, the dynamic torque of each brake wheel at the last moment, and the maximum variable quantity of the torque change of each brake wheel, determining the dynamic torque of each brake wheel at the current moment based on the actual variable quantity of the torque of each brake wheel, and determining the current dynamic torque as a new dynamic torque at the previous moment in response to the fact that the dynamic torque of each brake wheel at the current moment is different from a target brake torque corresponding to each brake wheel, and determining a new current dynamic torque corresponding to each brake wheel according to the new dynamic torque at the previous moment, and continuously adjusting and updating the dynamic torque of each brake wheel at the current moment, so that each brake wheel synchronously reaches the corresponding target torque from the dynamic torque at the current moment. The problem that the brake wheels cannot synchronously reach the corresponding target torques is solved, and the stability of the vehicle in the braking process is guaranteed.
本申请提供了一种车辆制动方法及系统,方法包括:根据各制动轮对应的目标制动转矩、各制动轮在上一时刻的动态转矩和各制动轮的转矩变化的最大变化量确定各制动轮转矩的实际变化量,基于各制动轮转矩的实际变化量确定各制动轮在当前时刻的动态转矩,响应于各制动轮当前时刻的动态转矩与所述各制动轮对应的目标制动转矩不同,将所述当前动态转矩确定为新的上一时刻的动态转矩,从而根据新的上一时刻的动态转矩确定各制动轮对应的新的当前动态转矩,通过不断调整更新各制动轮当前时刻的动态转矩使得各制动轮同步从当前时刻的动态转矩到达其对应的目标转矩,避免了各制动轮不能同步到达其对应的目标转矩的问题,保证车辆制动过程中的稳定性。
