Abstract
Taking the change of vehicle’s vacuum pressure and brake pedal force under certain test conditions as the research object, a test and evaluation method for the matching performance of the vehicle vacuum source is established. For the poor matching performance of an electric vehicle’s vacuum source, the optimization scheme is proposed. According to the theory of fluid mechanics and vacuum design, the dynamic vacuum pressure’s simulation model is established. The simulation results show that the optimization scheme is feasible. Finally, the experimental results show that the matching performance of the electric vehicle’s vacuum source is obviously improved after adopting the optimization scheme.
