The invention discloses a hybrid vehicle energy distribution method and device based on predictive cruise control, electronic equipment and a vehicle. The method comprises the steps that the cruise speed and the optimal cruise requirement are preset, possible speed trajectories of the vehicle on the road section ahead are determined, and under the condition that the optimal cruise requirement is met, the speed trajectory with the minimum cost function value in all the possible speed trajectories is selected as the optimal speed trajectory, the cost function comprises at least the following cost factors: a vehicle energy consumption function and a travel time function, the optimal speed trajectory is used as a target vehicle speed trajectory for predictive cruise control of the hybrid vehicle, and the optimal speed trajectory is used as a target vehicle speed trajectory for predictive cruise control of the hybrid vehicle depending on the remaining charge of the hybrid vehicle and the optimal speed trajectory. A vehicle speed threshold for switching between battery operation and fuel operation of the hybrid vehicle is obtained. The method can find an optimal speed boundary value for a hybrid vehicle using a battery and using fuel based on predictive cruise control.

    本发明公开了基于预测性巡航控制的混合动力车辆能量分配的方法、装置和电子设备以及车辆。该方法包括:预给定巡航速度和最优巡航要求,确定车辆在前方路段上的可能的速度轨迹,在满足最优巡航要求的情况下,选择各个可能的速度轨迹中成本函数数值最小的那条速度轨迹作为最优速度轨迹,其中,成本函数至少包括如下成本因子:车辆能耗函数和行车时间函数,将最优速度轨迹作为用于混合动力车辆的预测性巡航控制的目标车速轨迹,其中,依赖于混合动力车辆的剩余电量和最优速度轨迹,得到在混合动力车辆的电池运行与燃油运行之间进行切换的车速阈值。该方法能够找到基于预测性巡航控制的混合动力车辆使用电池和使用燃油的最佳速度分界值。
