| Abstract: | In view of the time-varying feature of parameters of electronic vacuum booster(EVB) in the active regulation of braking pressure,its control algorithm is designed based on model reference adaptive control theory,and the stability of the control system is proved by Lyapunov theory.In addition,a threshold of braking pressure changing rate is set as the activating condition of emergency brake assist(EBA) function for reducing system cost.Test results show that the braking pressure regulating algorithm can effe... |
