The Measurement for Performance Parameter of Automobile Braking System with Electronic Vacuum Booster

This paper measures the performance parameter of the automobile braking system with Electronic Vacuum Booster (EVB) through real vehicle experiment. According to the data collected from the experiment, the performance parameters of EVBs in different cars are not the same. The performance parameters of the EVB in both test cars can be separated into three parts. For example, when the desired braking intension, in other words the input signal of electronic vacuum booster, is less than 7, the braking effect is not obvious; when the desired braking intension is between 7 similar to 40, the relationship between the desired braking intension and the acceleration is found to be linear variation; when the desired braking intension is greater than 40, the wheels will be locked and the acceleration is constant. Then we get the performance parameter of automobile braking system with electronic vacuum booster through linear regression. The results can be used for automatic brake control. (C) 2013 The Authors.
