The invention provides a hybrid vehicle energy consumption optimization method and device, equipment and a storage medium, and the method comprises the steps: obtaining a vehicle speed-time curve (i.e., a driving curve) when a hybrid vehicle drives on a target path; performing torque distribution iterative optimization on each working point selected according to a certain step length on the driving curve by taking the optimal comprehensive efficiency as a target, and determining a torque combination (including motor torque and engine torque) of each working point; based on a bubbling method, determining a gear combination (including a motor gear and an engine gear) of each working point by utilizing the torque combination and the vehicle speed corresponding to each working point; and controlling the hybrid vehicle to run on the target path according to the gear combination and the torque combination of each working point. According to the scheme, global optimization is carried out according to the driving curve of the vehicle on the target path, so that the engine torque and the motor torque are distributed according to the torque combination with the highest comprehensive efficiency at each moment when the vehicle runs on the target path, and the energy consumption of the hybrid vehicle is reduced to the maximum extent.

    本申请提供一种混动车辆能耗优化的方法、装置、设备和存储介质,方法包括,获得混动车辆在目标路径上行驶时的车速‑时间曲线(即行驶曲线);以综合效率最优为目标对行驶曲线上按一定步长选取的每一工作点进行扭矩分配迭代寻优,确定每一工作点的扭矩组合(包括电机扭矩和发动机扭矩);基于冒泡法,利用每一工作点对应的扭矩组合和车速,确定每一工作点的挡位组合(包括电机挡位和发动机挡位);根据各个工作点的挡位组合和扭矩组合控制混动车辆在目标路径行驶。本方案根据车辆在目标路径的行驶曲线进行全局优化,从而确保车辆在目标路径行驶时每一时刻都按综合效率最高的扭矩组合来分配发动机扭矩和电机扭矩,最大程度地降低混动车辆的能耗。
