Automatic control method of automobile transmission based on fuzzy PID
In order to improve the target speed tracking level of car transmissions and enhance the power performance of cars,a fuzzy PID based automatic control method for car transmissions is studied.Determine the target speed of the car,calculate the deviation between the target speed and the actual speed,and the rate of change of the speed deviation.Use the above results as inputs to the PID controller.Using the PID controller after parameter tuning,determine the control variables of the car gearbox and control the car transmission mechanism to output the ideal speed.The experimental re-sults show that this method can accurately track the speed ratio of the car's gearbox when the car is driving in a state of step signal,slope signal,and sine signal.The control effect and dynamic tracking performance are superior,providing a good control strategy for maintaining the optimal power performance of the car.
