The invention relates to a distributed wheel edge driving and central driving hybrid driving system and a vehicle, belongs to the field of passenger vehicles and commercial vehicles, and aims to solve the problems that an existing single-motor driven vehicle cannot fully utilize the tire adhesive force, and a single motor needs to consider too many working conditions in order to guarantee the vehicle dynamic property, so that a high-efficiency area cannot be independently optimized according to specific working conditions, and the service life of the vehicle is influenced. The hybrid drive system at least comprises two drive shafts, the drive shafts in the last row are driven in a wheel edge distributed mode, and the drive shafts in the front row are driven in a central mode. The distributed drive comprises a wheel edge drive motor, and the wheel edge drive motor drives the motor through a speed reducer; the central drive comprises a drive motor, the drive motor is connected with half shafts on the two sides through a speed reduction device, and the system drive motor can output different moments to improve the control performance of the vehicle according to signals such as longitudinal and lateral acceleration and yaw velocity of the vehicle.

    本发明涉及一种分布式轮边驱动与中央驱动混合驱动系统及车辆,属于乘用车和商用车领域,目前单电机驱动车辆,无法充分利用轮胎附着力,且为保证车辆动力性,单电机需要兼顾工况太多,导致高效区无法根据特定工况进行单独优化,本发明提供的混合驱动系统至少包括两个驱动轴,最后排的驱动轴采用轮边分布式驱动,前一排的驱动轴采用中央驱动;分布式驱动包括轮边驱动电机,轮边驱动电机通过减速器驱动电机;中央驱动包括驱动电机,驱动电机通过减速装置连接两侧半轴,系统驱动电机可以根据车辆纵向、侧向加速度和横摆角速度等信号,同时输出不同力矩改善车辆操控性能。
