The invention discloses a braking control method and system and a computer readable storage medium. The braking control method comprises the steps that the total deceleration requirement and the total braking force requirement of a vehicle are determined; based on the total deceleration demand, a preliminary energy recovery equivalent braking force is determined. And according to the initial energy recovery equivalent braking force, target energy recovery torque and target energy recovery equivalent braking force corresponding to the target energy recovery torque are determined. And the difference value between the total braking force demand and the target energy recovery equivalent braking force is determined, and the target wheel end braking force is obtained. The target energy recovery torque is responded through the energy recovery system, and the target wheel end braking force is responded through the braking system. The initial energy recovery equivalent braking force determined according to different total deceleration requirements is different, the initial energy recovery equivalent braking force can be determined according to the current actual total deceleration requirement, the numerical value of the energy recovery torque can be increased conveniently, and the energy recovery rate is increased.
本申请公开一种制动控制方法、控制系统及计算机可读存储介质,制动控制方法包括:确定车辆的总减速度需求及总制动力需求。基于总减速度需求,确定初步能量回收等效制动力。根据初步能量回收等效制动力,确定目标能量回收扭矩和与目标能量回收扭矩对应的目标能量回收等效制动力。确定总制动力需求和目标能量回收等效制动力的差值,得到目标轮端制动力。目标能量回收扭矩通过能量回收系统进行响应,目标轮端制动力通过制动系统进行响应。不同的总减速度需求确定出的初步能量回收等效制动力不同,可以根据当前实际的总减速度需求,确定初步能量回收等效制动力,便于增大能量回收扭矩的数值,提高能量回收率。
