Abstract

The pass ability improvement of electric vehicles on bisectional ramps were done based on the invented dual-mode coupling drive systems. The torque output characteristics of the dual-mode coupling drive systems on a bisectional pavements and the pass ability control programs were analyzed. Then,the judgment rules of the mode switching control triggers were established according to the thresholds of the drive wheels slip ratios. Aimed at the initiative to adjust the rotational speeds of the drive motors in the processes of changing modes,fuzzy-PID controllers were established. The predictive function controllers were established according to the reference angular displacement curves of the mode switching actuators. Finally, the torque output characteristics and the actual mode-switching control effectiveness of the dual-mode coupling drive system were verified by comparison with other driving modes with bench and real car tests. The results show that the torque output characteristics of the dual-mode coupling drive system are very much in line with the technical requirements of electric vehicles. The flexible mode switching control functions improve the vehicle pass ability greatly on the bisectional ramps.
