The invention discloses a hybrid mode crawling control method for a dual-motor power split hybrid power system, and relates to a hybrid power automobile technology. Judging whether a creeping sign of the vehicle is erected or not; if the crawling mark is erected, the rotating speed and the torque of an engine are calibrated according to the crawling target vehicle speed and the wheel side required torque; the rotating speed of a first motor is dynamically analyzed according to the target crawling speed and the rotating speed of an engine, so that the target rotating speed of the first motor is obtained; the torque of the second motor is dynamically analyzed according to the wheel side demand torque and the engine torque, so that the target torque of the second motor is obtained; the engine outputs the calibrated rotating speed and torque, the first motor outputs the target rotating speed, and the second motor outputs the target torque, so that the vehicle runs at the target crawling speed and the required wheel torque. According to the invention, the smoothness and the dynamic property of the automobile under the creeping working condition are met, and meanwhile, the oil consumption problem of the automobile is also considered.

    本发明公开了双电机功率分流混合动力系统混动模式蠕行控制方法,涉及混合动力汽车技术。判断车辆的蠕行标志是否树立;若所述蠕行标志树立,则根据蠕行目标车速以及轮边需求扭矩标定发动机的转速和扭矩;根据所述蠕行目标车速以及发动机转速对第一电机的转速进行动态分析,以获取第一电机的目标转速;根据轮边需求扭矩以及发动机扭矩对第二电机的扭矩进行动态分析,以获取第二电机的目标扭矩;所述发动机输出标定的转速和扭矩、第一电机输出目标转速、第二电机输出目标扭矩,以使所述车辆以蠕行目标车速以及轮边需求扭矩行驶。本发明满足汽车蠕行工况的平顺性与动力性,同时也兼顾到了汽车的油耗问题。
