The invention provides a vehicle energy recycling method, an energy recycling system and a vehicle. The energy recycling method comprises the following steps of receiving a brake signal sent by a cab;judging whether a battery SOC value of a battery is lower than a first preset value or not and whether a vehicle has a high-voltage system fault or not; and when the SOC value of the battery is lowerthan a first preset value and the vehicle has no high-voltage system fault, sending a charging instruction to make a motor enter a power generation mode so that braking energy generated by the vehicle is transmitted to the motor through a gearbox, and the braking energy is converted into electric energy by the motor to be stored in the battery. According to the vehicle braking energy recycling method, control logic is simple, an engine load can be effectively reduced, and recycling of vehicle braking energy is effectively achieved.
本发明提供了一种车辆能量回收利用方法、能量回收利用系统及车辆,能量回收利用方法包括以下步骤:接收到驾驶室发出的制动信号;判断电池的电池SOC值是否低于第一预设值以及车辆是否存在高压系统故障;当所述电池SOC值低于第一预设值,且车辆无所述高压系统故障时,发送充电指令,以控制电机进入发电模式,从而使得车辆产生的制动能量通过变速箱传递给所述电机并由所述电机将所述制动能量转化为电能存储在所述电池中。本发明的车辆制动能量回收利用方法,控制逻辑简单,可以有效减少发动机负载,有效实现车辆制动能量的回收利用。
