Design and Simulation of Energy Saving Driving Strategy for Pure Electric Bus Entering and Leaving Stops

Focusing on the obvious speed fluctuation and high energy consumption in the process of bus entering andleaving stops, this study collected the real driving data of pure electric buses and analyzed the driving behaviorcharacteristics with three indicators: the relationship between speed and distance, the distribution interval ofacceleration, and the time of entering and leaving stops. The energy consumption performance was analyzed bycounting energy consumption per 100 km and the change trend of instantaneous energy consumption and acceleration.On this basis, the process of bus entering and leaving stops is divided into fixed speed section, adjustment section, andrecovery section, and the scenes of entering and leaving stops were divided into three categories according to theinfluence of the bus had parked in the stop. The process of entering and leaving stops can be simplified as a"deceleration and acceleration" process. The acceleration strategy with acceleration characteristic parameters andconstant deceleration strategy was proposed. Based on these strategies, energy-saving driving strategies were proposedfor the three entering and leaving stops scenarios. Finally, the effectiveness of the energy-saving driving strategy wasverified based on the simulation of AVL Cruise. The results show that the proposed driving strategy can save 12.17%~44.43% of electric energy in the process of entering and leaving stops compared with the original driving situation,which has considerable energy-saving potential.
