A new type of regenerative braking system and corresponding control strategy are designed in order to decrease the fuel consumption of hybrid electric buses significantly and ensure brake safety.A new s eries regenerative braking system IS designed based on high speed switch valve,ABS,driving motor,and baRery energy storage device for the sake of coordinately controlled between mechanical braking and regenerative braking,and between ABS and RBS.All these are done on a series hybrid electric bus.The simulation model of objected bus with regenerative braking system is built by using Matlab/Simulink software and simulated on Chinese typical city bus driving cycle;Test bed of regenerative braking system is built with dSPACE and hardware of traditional air brake system,performallces of coordinated control between mechanical braking and regenerative braking,and between ABS and RBS are tested on the test bed and analyzed.The result shows that the regenerative braking system is safe in braking process,ABS can work well without being disturbed by RBS;mechanical braking and regenerative braking are distributed accordingly relate to the command of control strategy,thus competence of RBS can be exploited farthest;and fuel consumption can be significantly decreased,more thall half of the bus's kinetic energy (except for the rolling resistance,air resistance and other friction)Can be recovered on Chinese typical city bus driving cycle.
