Theoretical Analysis and Testing Research for Automobile Anti-braking System

This paper analyzes the automobile braking process and the law of changes in angular velocity,deceleration,acceleration of the wheel during braking.A wheel dynamics model is established based on facts.Choosing deceleration and acceleration as the control parameters according to maximum braking force produced by limit deceleration,based on EQ140 braking system,an electronic anti braking testing system is established.The system is tested on the laboratory barratte for several times and proved to be effective.The favourable conclusion and experence obtained will be helpful in further researches in this field.
