The invention discloses a dual-motor driving system for integrated vehicle control of an electric vehicle. Double motors are a front-drive motor and a rear-drive motor. The dual-motor driving system is provided with a motor controller, and the motor controller comprises a control unit and a driving module; and the control unit realizes all functions of the whole vehicle controller and functions of a main control part of motor control. By the adoption of the technical scheme, efficiency matching with the whole vehicle working condition is achieved, and the cruising ability is improved; under the condition that the heat dissipation power of the double three-phase motors meets the normal running condition of the whole vehicle, one set of power assembly can serve as a PTC function and can be used for preheating battery starting and low-temperature heating work, meanwhile, the PTC power and the working power are reduced, and full utilization of energy is achieved; and even if one group of output fails, the other group of output can still work and can still output high power under low voltage, so that the power performance and the safety performance of the vehicle are improved.

    本发明公开了一种电动汽车集成车辆控制的双电机驱动系统,双电机为前驱电机和后驱电机;双电机驱动系统设置电机控制器,电机控制器包括控制单元和驱动模块;控制单元实现整车控制器的全部功能和电机控制的主控部分功能。采用上述技术方案,实现了与整车工况效率匹配和续航能力的提升;双三相电机散热的功率在满足整车正常行驶条件下,其一组功率组件可以充当PTC功能,可以用来预热电池启动和低温加热工作,同时降低PTC功率及工作时功率,实现能量的充分利用;即便一组输出失效,另一组仍可工作且低压下仍可大功率输出,提高车辆动力性能和安全性能。
