A Novel Control Algorithm for Electronic Braking System Based on Braking Comfort and Safety

摘要

EBS(Electronic Braking System) can improve the braking performance of commercial vehicles significantly.In this paper,a control algorithm for EBS has been proposed,which consists of Driving Identification Module,Delay Control Module and Braking Force Distribution Module.Driving Identification Module can recognize the non-emergency braking situation according to the signal of the electronic braking pedal.When the same amount of pressure is applied on the pedal,Delay Control Module can guarantee that the vehicle brake in the same manner,irrespective of the road condition and the amount of load it is carrying.Braking Force Distribution Module regulates the braking force on front and rear axle by comparing the slip-ratios on every axle.As a result,the optimum braking pressure on different axles can enhance the safety and balance the brake wear.The performance of the control algorithm has been simulated utilizing 17-DOF vehicle dynamic model.The results show that the control algorithm can provide a good braking feeling and the braking performance of the vehicle is perfect.
