The invention relates to the field of vehicles, and provides a vehicle energy management method and device and a vehicle. The method comprises the steps that when a target vehicle is in an accelerated or constant-speed driving process, if the current connection state of the target vehicle and a wire net is connection, the target vehicle is connected with the wire net; determining the first output power of the power battery, the second output power and the third output power of the voltage conversion device and the target working point of the engine based on the current output voltage of the wire net, the current charge state of the power battery and the current required driving power of the target vehicle; and controlling the motor system to provide first driving power based on the first output power, the second output power and a preset working model of each motor in the motor system, controlling the engine to provide second driving power based on the target working point location, and performing charging control on the power battery based on the third output power. According to the invention, the requirements of environmental protection and energy conservation can be effectively met while the efficient operation of the vehicle is ensured.

    本发明涉及车辆领域,提供一种车辆能量管理方法、装置及车辆,该方法包括:在目标车辆处于加速或匀速行驶的过程中,若目标车辆与线网的当前连接状态为连接时,基于线网的当前输出电压、动力电池的当前荷电状态以及目标车辆的当前需求驱动功率,确定动力电池的第一输出功率、电压转换装置的第二输出功率和第三输出功率以及发动机的目标工作点位;基于第一输出功率、第二输出功率,以及电机系统中各电机的预设工作模型控制电机系统提供第一驱动功率,基于目标工作点位控制发动机提供第二驱动功率,以及基于第三输出功率对动力电池进行充电控制。本发明能够在保证车辆的高效运行的同时,有效满足环保和节能的要求。
