Personalized Controller Design for an Electro-mechanical Booster Braking System

Electro-mechanical booster (Ebooster) braking system is becoming the mainstream of braking system because its independence from vacuum source, rapid response and high security. In particular, the Ebooster braking system can provide personalized assist characteristics. In fact, Drivers with various driving style have different braking demands, and single assist characteristic can no longer meet the individual demands in intelligent vehicles. So, based on the driver's personalized braking demands, a personalized controller for an Ebooster braking system is designed in this paper. Firstly, personalized braking demands are analyzed. Then a self-designed Ebooster braking system is introduced and modeled. Based on this, the mathematical equations of the assist characteristics is obtained and a personalized controller is designed for different braking styles. Finally, the overall performance of the controller designed in this paper is proven effective by simulation tests.
