The invention relates to the field of vehicle control, in particular to an energy recovery method for abrupt slope slow descent and equipment. The method comprises the steps that when determining that the vehicle state meets the abrupt slope slow descent condition, an abrupt slope slow descent instruction is sent to a wheel brake, and an energy recovery instruction is sent to a vehicle control unit VCU; in the process of applying the mechanical braking force and the electromagnetic reverse dragging force to the wheels, the actual vehicle speed of the vehicle is compared with the target vehicle speed of vehicle downhill; according to the comparison result, a first instruction for adjusting the mechanical braking force is sent to the wheel brake, and/or a second instruction for adjusting an electromagnetic reverse dragging force is sent to the VCU, so that the actual vehicle speed approaches the target vehicle speed under the condition that the mechanical braking force and the electromagnetic reverse dragging force are applied to the wheels. According to the energy recovery method for steep slope slow descent, energy recovery can be conducted when the vehicle goes downhill, meanwhile, the vehicle goes downhill at the stable speed, and driving safety is guaranteed.
本发明涉及车辆控制领域，尤其涉及一种用于陡坡缓降的能量回收方法和设备。其中，上述方法包括：确定车辆状态满足陡坡缓降条件时，向车轮制动器发送陡坡缓降指令以及向整车控制器VCU发送能量回收指令；在对车轮施加所述机械制动力以及所述电磁反拖力的过程中，将车辆的实际车速与车辆下坡的目标车速进行比较；根据比较的结果，向车轮制动器发送调整机械制动力大小的第一指令，和/或，向VCU发送调整电磁反拖力大小的第二指令，以使车轮在施加机械制动力以及电磁反拖力的情况下实际车速趋近于所述目标车速。本发明实施例提供的用于陡坡缓降的能量回收方法，在车辆下坡时也能够进行能量回收，同时使车辆以稳定的速度下坡，保障行车安全。
