The embodiment of the invention provides an energy recovery control method, a vehicle control unit, an energy recovery system and a vehicle. The method applied to the vehicle control unit comprises the steps: detecting the state of high-voltage electric appliances when an energy recovery starting signal is detected; when it is detected that at least one high-voltage electric appliance is in an operation state, obtaining first power requested by the battery for energy recovery and second power of each high-voltage electric appliance in the operation state; summing the first power and the secondpower to obtain first energy recovery power; and sending a first energy recovery instruction to a motor according to the first energy recovery power. According to the technical scheme, the vehicle control unit can increase or decrease the energy recovery power according to the state of the high-voltage electric appliances within the motor recovery capacity range, the safety of the power battery is guaranteed while the recovery power of the power battery is guaranteed, and the driving range of a vehicle can be increased.
本发明的实施例提供了一种能量回收的控制方法、整车控制器、能量回收系统及车辆,其中,应用于整车控制器的方法包括:当检测到能量回收启动信号时,检测高压用电器的状态;当检测到至少一个高压用电器处于运行状态时,获取电池请求能量回收的第一功率以及每一个处于运行状态的高压用电器的第二功率;将第一功率以及第二功率求和,得到第一能量回收功率;根据第一能量回收功率,发送第一能量回收指令至电机。在本发明的技术方案中整车控制器在电机回收能力范围内,能根据高压用电器的状态增大或减小能量回收功率,在保证动力电池的回收功率的同时保证动力电池的安全,有利于提高车辆的续驶里程。
