AI Technical Summary

Problems solved by technology

It can be seen that the control loop in the existing control device for simulating the driver is a closed-loop control, and its PI or PD controller is difficult to achieve a good control effect on the strongly nonlinear, time-varying complex system and the system whose model is unclear , does not consider the acceleration or deceleration process of the driver operating the accelerator / brake pedal in the actual operation of the car

[0005] To sum up, the existing control device for simulating the driver only uses the vehicle speed deviation as the input signal, and adopts the conventional PI or PD controller, but because the conventional PI or PD controller is a nonlinear, time-sensitive The variable and delayed complex system is difficult to achieve a good control effect, resulting in inaccurate output control signals, which are quite different from the driver's actual operation control, so that it cannot meet the strong nonlinearity of the vehicle system in the actual operation of the simulated vehicle. The time deformation and delay characteristics make the simulation performance of the whole simulation system low and the simulation effect is poor
