Research Of The ABS Fuzzy Control For Full-Vehiele Based On CARSIM

Automotive anti-lock braking system ((Anti-lock Braking System, ABS)) is to improve automotive active safety device, The main purpose is to be able to automatically adjust the wheel brake pressure when the emergency braking of the vehicle, To prevent the wheels from locking. Improve the braking of the vehicle directional stability and steering maneuverability, Improve the braking performance of the car, in order to ensure the safety of the driver and passengers. Therefore, as an effective vehicle active safety device, ABS research becomes urgent.This paper first introduces the significance of the study of the ABS system, the basic components and working principle; Summary of automotive anti-lock braking system development status quo and development trend of domestic and foreign; The comparative analysis of their performance impact on the the various ABS arrangement of the control strategy.Secondly, the current ABS research areas in the vehicle model is relatively simple defect, This article the to build automobile dynamics simulation model parametric modeling based Carsim software, And in Matlab/Simulnk environment were designed automobile ABS fuzzy controller parameters self-adjusting fuzzy PID controller; Automobile dynamics simulation model and ABS controller model combination, constituted to study the the ABS performance of joint simulation model.Subsequently designed three different road, Will establish a joint simulation models were placed in three road surface conditions to simulate and analyze, And design of the slip rate parameters can be automatically adjusted according to different road expect smart pavement slip rate charged object recognition system. The simulation results show that the identification pavement pavement recognition system; articles designed fuzzy controller and parameters self-adjusting fuzzy PID controller ideal braking effect, Especially parameters self-adjusting fuzzy PID controller, Adaptive pavement mutation is relatively high, relatively strong robustness, more desirable to obtain a braking effect.
