Control Strategy for Hill Starting of Electric Vehicle

Hu Jian-Jun, Chen Xi, Du Rui and Zhang Yi

In order to solve the problem of easy slipping on hill during the starting process of electric vehicle, the hill starting control strategy was established on the basis of hill-start assist system. The state equation of the slope recognition was achieved by simplifying the vehicle longitudinal dynamics equation and then a Luenberger observer was designed based on this state equation to recognize the road slope online. The problem of function trigger and the Hill Starting Aid valve control in the hill-start assist system had been solved by the slope recognition and starting resistance calculation. The simulation results show that the designed observer could recognize the road slope effectively and the system could meet the requirements of safety and driving comfort in hill starting process.
