The invention provides a vehicle with a double-motor electric drive axle and a drive method. Power output by a first drive motor M1 is transmitted to a third cylindrical gear transmission speed reduction module; the power output by the first driving motor M1 is transmitted to a first half shaft and a second half shaft to drive a first wheel and a second wheel; and power output by a second driving motor M2 sequentially passes through a first gear transmission speed reduction module and a second gear transmission speed reduction module and is converged with power output by the first driving motor M1 at the third gear transmission speed reduction module. By configuring different working modes and control strategies, different coupling of driving force under different vehicle speeds and different loads is achieved, real-time power distribution is achieved, the two motors share two gears for gear shifting, the gear shifting reliability is guaranteed, meanwhile, the output torque of the motors can be further improved, the motors can work in a high-efficiency interval, and the dynamic property and economical efficiency of the whole vehicle are improved.

    本发明提供一种具有双电机电驱动桥的车辆及驱动方法,第一驱动电机M1输出的动力传递到第三圆柱齿轮传动减速模块;再将第一驱动电机M1输出的动力传输到第一半轴和第二半轴,来驱动第一车轮和第二车轮;第二驱动电机M2输出的动力依次通过第一齿轮传动减速模块、第二齿轮传动减速模块并在第三齿轮传动减速模块与第一驱动电机M1输出的动力汇合。通过配置不同的工作模式和控制策略,实现在不同车速、不同负载下的驱动力不同耦合,实现动力实时分配,且双电机共用两挡换挡,保证换挡可靠性的同时可进一步提高电机输出扭矩和电机工作在高效率区间,提高整车动力性、经济性。
