The invention discloses an electric vehicle and a double-winding motor control system thereof, and relates to the technical field of motor control. The electric vehicle includes a controller, the controller comprises a detection device used for detecting the operation state of the motor and an execution device used for selecting the drive circuit. The output end of the detection device is connected with the input end of the controller through a wire harness, the input end of the execution device used for selecting the drive circuit is connected with the output end of the controller through a wire harness, and the execution device comprises a sensor arranged on the motor and used for detecting the road surface inclination, a low-speed winding and a high-speed winding, by arranging the roadsurface inclination sensor, when the electric vehicle runs, whether the road surface is flat or not can be judged by the inclination sensor according to the inclination of the road surface, so that the motor is switched into the corresponding driving circuit, the bumping feeling caused by uneven road surface when the electric vehicle is driven can be reduced, and the driving experience of a driveris improved.

    本发明公开了一种电动车及其双绕组电机控制系统,涉及电机控制技术领域。本发明包括控制器,控制器包括用于检测电机运行状态的检测装置和用来选择驱动电路的执行装置,检测装置的输出端通过线束与控制器的输入端连接,用来选择驱动电路的执行装置的输入端通过线束与控制器的输出端连接,执行装置包括设置在电机上用于检测路面倾斜度的传感器、设置在电机上的低速绕组和高速绕组。本发明通过设置路面倾斜度传感器电动车在行驶时可以根据路面的倾斜度由倾斜度传感器判断路面是否平整,而使电机切换成相对应的驱动电路,可以减少驾驶电动车时由于路面不平整而产生的颠簸感,增加驾驶人员的驾驶体验。
