【Abstract】 Regenerative braking system is the feature of hybrid electric vehicle.The problem on braking force distribution for the HEV was studied,and the braking theory of the traditional vehicle and the new trait of the HEV were analyzed.In order to maximize the utilization of the regenerative braking system to increase the regenerative energy efficiency,a control strategy was proposed to determine the brake force distribution for the PHEV.Finally the simulation was carried out by the AVL-Cruise and Matlab,and the braking forces under different conditions were contrasted.The simulation result shows that the strategy which considers the deceleration,terrain adhesive coefficient and characteristic of the electric motor can distribute the braking forces rightly and maximize the utilization of the regenerative braking system to increase the regenerative energy efficiency.更多还原
