Large impulsion existed in the process of CVT start-up, the change of clutch engagement pressure and friction coefficient are the main reasons that caused starting impulsion, friction coefficient is uncontrollable, impulsion inhibition could be realized by control the clutch engagement pressure. The impulsion inhibition effect, which based on starting clutch fuzzy control strategy, is mainly introduced. The whole mathematical model which based on the fuzzy control is established. The simulation analysis of flatland start-up is accomplished. The results show that the fuzzy control strategy could restrain the impulsion significantly, and has a large use value.
