Abstract

Regenerative braking is a major means of hybrid vehicle to improve vehicle fuel economy. To ensure the safety of brake is the basic requirement of vehicles. This article discusses that the basic principle of regenerative braking system of hydraulic hybrid bus is a compound system based on ground coupling, and introduces regenerative braking force distribution strategy through integrated control of machinery and hydraulics according to the demands for driver. The simulation model is established based on MATLAB/SIMULINK/STATAFLOW with the method of system simulation. The effect on braking energy recovery demand condition under the different road adhesion conditions, and different braking requirements and fuel economics under typical urban driving cycle is analyzed. Results of the simulation show that the vehicle under the condition of the above simulation has good comprehensive performance.
