Abstract: Ecological driving improves fuel economy and reduces vehicle emissions by changing the driver's driving behavior, such as starting smoothly, avoiding sharp acceleration and deceleration, and avoiding prolonged idling. In order to clarify the impact of driving behavior on ecological driving, this paper sorts out the research status of driving behavior and ecological driving by domestic and foreign scholars in recent years, and introduces the ecological driving assistance system that applies ecological driving technology in practice. Combined with the ecological driving research method of fuel vehicles, the ecological driving behavior of pure electric buses is analyzed. It is found that driving behaviors such as increasing vehicle speed, avoiding low-speed driving, controlling acceleration in a small range, and slowly pressing the accelerator pedal can effectively reduce fuel consumption and achieve energy saving and emission reduction, and for pure electric vehicles, excess energy can be recovered through reasonable braking and deceleration. It provides a new idea for evaluating the driver's ecological driving behavior and improving the level of ecological driving.
