The invention discloses a method for optimizing a power system of an automatic driving electric vehicle, which comprises the following steps of: establishing a vehicle feedback system power model which comprises a driver model, a monitoring controller model and a vehicle model; setting a driving circulation mode, and simulating all power system schemes in the power system architecture through a whole vehicle model by taking speed limitation, a parking position, a travel distance and travel time in the driving circulation mode as constraint conditions of an automobile feedback system power model to obtain an optimal speed track of each power system scheme; the energy consumption and the power system peak power corresponding to each optimal speed track are obtained; and the power system scheme with the minimum energy consumption and the minimum power system peak power is selected as the optimal power system scheme.

    本发明公开了一种自动驾驶电动汽车动力系统优化方法,包括:建立汽车反馈系统动力模型,其包括:驾驶员模型、监控控制器模型和车辆模型;设定驾驶循环模式,并且以驾驶循环模式中的速度限制、停车位置、行程距离和行程时间作为汽车反馈系统动力模型的约束条件,对动力系统架构中所有的动力系统方案通过整车模型进行仿真,得到每个动力系统方案最优速度轨迹,并得到每个最优速度轨迹对应的能源消耗量和动力系统峰值功率;选出能源消耗量最小、并且动力系统峰值功率最小的动力系统方案,作为最优动力系统方案。
