also made out the related three-dimensional modeling and animation.

In the design of electrical control, through the braking process of car design the

application of vacuum brake booster pump system of automobile traffic flow chart

and design the hardware circuit diagram of this control method.

Through this research project will develop a set of independent application of

vacuum brake pump brake system. Knowledge structure of the network will be

multi-disciplinary integration, the research process, including mechanical design,

hydraulic design, automotive design, mechanical electronics and vacuum design.

Key words: vacuum booster pump, brake system, brake master cylinder
