Research on adaptive stability control of distributed drive electric vehicles
In response to the complexity and variability of vehicle driving conditions,a fuzzy adaptive stability control strategy was proposed to improve the effectiveness of vehicle driving stability control.To weaken the jitter of sliding mode variable structure and increase the adaptability of switching gain function,fuzzy control rules were used to dynamically adjust and determine the optimal value,which served as the basis for vehicle lateral stability control.To leverage the advantages of independent control of four-wheel drive and braking,the distribution of rotational torque for each wheel was optimized based on tire adhesion margin.The results of the single lane change test showed that the fuzzy adaptive stability control strategy effectively reduced the jitter of sliding mode variable structure control and improved the limit value of vehicle stability.
