【Abstract】 Taking an advanced single-shaft parallel hybrid electric bus as study objective,a reverse analytical method for regenerative braking strategy was proposed. First the test procedure was designed based on the preliminary test and the preset regenerative braking strategy parameters. Then a real vehicle test was conducted to analyze the effects of parameters. Analysis results show that vehicle speed determines whether the regenerative braking exists during the braking process; while motor speed and gear determine the process of regenerative braking,battery temperature and gear determine the quantity of motor torque and power. Testing with different handle modes,braking severity and road conditions,the regenerative braking strategies of different handles have been worked out. Finally,the correctness of the analytic strategy was validated with simulation.更多还原
