Eco-driving Strategy for Electric Bus Entering and Leaving Stops Considering Velocity Mode

The promotion of electric vehicles brings new opportunities to energy conservation and emission reduction. However, due to the differences in their dynamic systems, it also highlights a problem of high energy consumption of electric vehicles if the operation mode and driving habits of traditional fuel vehicles continue to be used. To increase inbound energy recovery and reduce outbound energy consumption, two eco-driving strategies were established by considering the actual inbound and outbound velocity mode. Firstly, natural driving data of electric bus rapid transit (E-BRT) was collected and the differences in energy consumption between electric and gasoline buses were analyzed. Secondly, the actual inbound and outbound velocity mode was deeply analyzed, and five driving strategies that consider driving mode in the process of entering and leaving stops were established separately. By comparing the energy consumption rate, the inbound and outbound eco-driving strategies were determined. Thirdly, an eco-driving strategy based on a NSGA-II was established based on the driving mode. Finally, the energy-saving benefits of the two strategies were verified using the actual inbound and outbound data under the three driving styles. The energy saving rate of the eco-driving strategies based on driving mode and NSGA-II is 17.04%/23.58%, 14.76%/21.48%, and 5.78%/ 13.21% for energy-consuming, general, and energy-saving driving styles, respectively. The proposed strategy demonstrated the highest energy-saving rate for energy-consuming driving styles, followed by general styles, and the lowest for energy-efficient driving styles. Compared to the eco-driving strategy based on driving mode, the strategy based on NSGA-II exhibited a 7.89% reduction in energy consumption. © 2024 Science Press. All rights reserved.
