The invention discloses an intelligent hybrid electric vehicle energy management method. The method comprises the steps that S01, vehicle driving traffic information, vehicle driving environment information and vehicle future driving environment information are obtained; s02, planning the expected driving speed of the vehicle; s03, the wheel end demand power and demand torque of the vehicle are obtained; s04, judging whether the vehicle is in a driving mode or a braking mode, executing a step S05 in the braking mode, and executing a step S06 in the driving mode; s05, when the absolute value of the required power is larger than the maximum generated power of the second motor, the second motor and the brake jointly provide the required power, and otherwise, the second motor independently provides the required power; and step S06, dividing the working mode of the vehicle according to the required power and the state of charge of the battery. The vehicle driving environment information can be obtained through the intelligent network connection technology, the vehicle driving state can be further optimized, and the energy-saving advantage of the hybrid electric vehicle can be better played.

    本发明公开了一种智能混合动力汽车能量管理方法,包括:步骤S01,获取车辆行驶交通信息、车辆行驶环境信息及车辆未来行驶环境信息;步骤S02,规划车辆期望行驶速度;步骤S03,获取车辆的车轮端需求功率和需求转矩;步骤S04,判断车辆处于驱动模式还是制动模式,制动模式执行步骤S05,驱动模式执行步骤S06;步骤S05,当需求功率的绝对值大于第二电机最大发电功率时,第二电机和制动器共同提供需求功率,反之,第二电机单独提供需求功率;步骤S06,根据需求功率和电池荷电状态来划分车辆工作模式。本发明可以通过智能网联技术获得车辆行驶环境信息,能够进一步优化车辆行驶状态,更好发挥混合动力汽车的节能优势。
