The invention relates to the technical field of motor control or regulation, and provides a multi-stage automatic speed regulation electric tricycle control system and method. The system comprises a driving motor, a gear shifting motor, a central controller, a gearbox and a clutch, the driving motor is connected with the gearbox through the clutch, and the gearbox is connected with driving wheels of the electro-tricycle and used for outputting driving torque of the driving motor to the driving wheels of the electro-tricycle; the gear shifting motor is connected with the gearbox through the switching device and used for gear adjustment. The central controller is connected with the driving motor and the gear shifting motor and used for detecting the operation states of the driving motor and the gear shifting motor so as to adjust the speed of the electric tricycle according to the operation states, and the driving motor and the gear shifting motor are brushless direct-current motors. Therefore, the optimal gear can be selected under the condition that the maximum current of the driving motor is not exceeded, the safe forward running of the electro-tricycle is ensured, and the safe operation of the electro-tricycle is also ensured.

    本申请涉及控制或调节电动机技术领域,提供了一种多级自动调速的电动三轮车控制系统和方法。该系统包括:驱动电机、调档电机、中央控制器、变速箱、离合器;驱动电机通过离合器与变速箱连接,变速箱与电动三轮车的驱动轮连接,用于将驱动电机的驱动转矩输出到电动三轮车的驱动轮上;调档电机通过切换装置与变速箱连接,用于档程调节;中央控制器分别与驱动电机、调档电机连接,用于对驱动电机以及调档电机的运行状态进行检测,以根据运行状态对电动三轮车的速度进行调节,其中,驱动电机、调档电机均为无刷直流电动机。由此,能够在保证不超过驱动电机的最大电流情况下,选择最优档程,保证电动三轮车安全向前行驶,同时又保证其安全运行。
