Decoupling method for modulation pulse input signal of electric speed controller of general car model

The invention relates to a general car model electric speed controller modulation pulse input signal decoupling method, belongs to the technical field of general car models, and realizes a scheme which can be directly used for decoupling composite control information controlled by a simple switching program. Four set ways are used, control over three gears is achieved, and braking and reversing are decoupled. Through corresponding matching of the standard speed data, the PWM duty ratio L1 and the maximum value of the forward driving force of the car model, under the condition that the PWM duty ratio L1 and the maximum value of the forward driving force of the car model are fixed, whether the highest forward speed control is normal or not in the general car model electric speed modulation process is detected according to the real-time speed data. When it is judged that the highest forward speed control is abnormal in the modulation process of the general car model electric speed controller, further judgment is
