Control method for dual-motor ultra-low-speed cruise

The invention discloses a control method for dual-motor ultra-low-speed cruise. When constant-speed cruise is started, determining a motor target rotating speed according to a set cruise target speed, and controlling a first motor to work by adopting a rotating speed control mode according to the motor target rotating speed; and detecting the actual torque of the first motor in real time, and controlling the second motor to increase or decrease the output torque by adopting a torque control mode according to the actual torque. During constant-speed cruise, the first motor and the second motor respectively adopt a rotating speed control method and a torque compensation method, so that the problem of asynchronous working modes of double motors is solved, the high-precision vehicle speed control requirement can be met, and high-load work of a single motor can be avoided. 本发明公开了一种双电机超低速巡航的控制方法。启动定速巡航时，根据设定的巡航目标速度确定电机目标转速，根据电机目标转速采用转速控制模式控制第一电机工作；实时检测第一电机的实际扭矩，根据实际扭矩大小采用扭矩控制模式控制第二电机增大输出扭矩或减少输出扭矩。本发明在定速巡航时，第一电机和第二电
