The embodiment of the invention provides a motor vehicle auxiliary braking method and device and a computer readable storage medium, and the method comprises the steps: determining a target braking gear of a first auxiliary braking device which does not have a kinetic energy recovery function when determining that an auxiliary braking processing condition is satisfied; for any first auxiliary braking device, an actual braking gear is selected according to the maximum braking power corresponding to each candidate braking gear; wherein the grade of the candidate braking gear is not higher than the target braking gear, and the sum of the maximum braking power corresponding to the candidate braking gear and the maximum braking power of the second auxiliary braking device with the kinetic energy recycling function is not smaller than the maximum braking power corresponding to the target braking gear; each first auxiliary braking device is controlled to brake at the corresponding actual braking gear, so that the motor vehicle is braked at the total power not smaller than the target braking power; and if the actual braking gear of the first auxiliary braking device is a non-target braking gear, the second auxiliary braking device performs auxiliary braking with non-zero power.

    本发明实施例提供一种机动车辅助制动方法、设备及计算机可读存储介质,包括:确定满足辅助制动处置条件时,确定不具备动能回收功能的第一辅助制动装置的目标制动挡位;对任一第一辅助制动装置,根据各候选制动挡位对应的最大制动功率选择实际制动挡位;其中,候选制动挡位等级不高于目标制动挡位,且候选制动挡位对应的最大制动功率与具备动能回收功能的第二辅助制动装置的最大制动功率之和不小于目标制动挡位对应的最大制动功率;控制各第一辅助制动装置以对应的实际制动挡位制动,以使机动车以不小于目标制动功率的总功率制动;其中,若存在第一辅助制动装置的实际制动挡位为非目标制动挡位,则第二辅助制动装置以非0的功率辅助制动。
