Abstract: Pure electric buses have the problem of limited range in actual operation, and the driver's driving behavior has a large impact on energy consumption. In order to further investigate the influence of driver driving style on energy consumption, this paper uses global positioning system (GPS) speedometer Pro to collect pure electric bus driving data, and uses K-Means mean clustering method to classify driving style into three categories: aggressive, normal and conservative based on acceleration standard deviation, and then based on theoretical energy consumption model through MATLAB to get the energy consumption of various driving styles, and analyze the influence of driving style on the energy consumption of each driving segment of pure electric buses. Then, the energy consumption of each driving style was obtained by MATLAB based on the theoretical energy consumption model, and the influence of driving style on the energy consumption of eachdriving segment of pure electric bus was analyzed. The results show that the energy consumption increases and then decreases with the increase of the average speed when driving at a uniform speed, and it is not related to the driving style; when driving at a non-uniform speed, the energy consumption tends to decrease with the increase of the average speed, and the more aggressive the driving style is in the same average speed range, the higher the energy consumption, in which the normal driving style has better economy when driving at a single acceleration, and the conservative driving causes the energy consumption to increase when driving at an acceleration more than 24.8%, aggressive driving will lead to more than 47.6% increase in energy consumption when accelerating.
