The invention discloses a power distribution method and device of a hybrid power vehicle and a vehicle control unit, and the power distribution method comprises the steps: obtaining the current vehicle speed and the current demand torque of the hybrid power vehicle; when it is determined that the driving mode of the hybrid vehicle is a parallel mode, the current SOC value of a power battery is determined, and the current required power of the hybrid vehicle is determined; and according to the current SOC value of the power battery, the current demand power and the engine economic line power of the hybrid power vehicle, the output power of an engine and the working power of a motor generator are distributed. According to the power distribution method, the corresponding output power of the engine and the working power of the motor generator in the parallel connection mode are distributed according to the current SOC value and the current demand power of the power battery and the engine economic line power of the hybrid power vehicle, so that the economical efficiency of the whole vehicle can be ensured to be excellent; and it can be guaranteed that the engine works at higher power when the requirement for low SOC or high power is met, and therefore the electricity protection performance of the whole vehicle is guaranteed.
本发明公开了一种混合动力车辆的功率分配方法和装置、整车控制器,所述功率分配方法,包括:获取混合动力车辆的当前车速和当前需求扭矩;确定混合动力车辆的驱动模式为并联模式时,确定动力电池的当前SOC值,并确定混合动力车辆的当前需求功率;根据动力电池的当前SOC值、当前需求功率和混合动力车辆的发动机经济线功率对发动机的输出功率和电动发电机的工作功率进行分配。本发明的功率分配方法,根据动力电池的当前SOC值、当前需求功率和混合动力车辆的发动机经济线功率分配并联模式下对应的发动机的输出功率和电动发电机的工作功率,既能保证整车的经济性做到优,又能保证在低SOC或者大功率需求时发动机工作在更大的功率,从而保证整车的保电性。
