Electric bus energy consumption estimation method based on data driving

Abstract

The invention discloses an electric bus energy consumption estimation method based on data driving. The electric bus energy consumption estimation method based on data driving comprises the steps of:S1, obtaining the real-time GPS track data of a vehicle, intelligent IC card data, the no-load weight of the vehicle and the auxiliary system power; S2, according to the driving distance and the driving time of adjacent track points in the GPS track data, calculating the speed, the acceleration and the gradient of the vehicle in an adjacent track point interval; S3, matching the intelligent IC card data with the GPS track data, and furthermore, in combination with the no-load weight of the vehicle, calculating the total weight of the vehicle in the adjacent track point interval; S4, accordingto the speed, the acceleration, the gradient and the total weight of the vehicle, calculating the running instantaneous power of the vehicle in the adjacent track point interval; and S5, according tothe instantaneous power in the step S4 and the auxiliary system power of the vehicle, calculating the total instantaneous power of the vehicle, and estimating the energy consumption of the vehicle according to the total instantaneous power of the vehicle. On the basis of the GPS track data and the intelligent IC card data, the electric bus energy consumption estimation method based on data drivingin the invention has a big role for analyzing the time-space characteristic of the energy consumption of an electric bus.

Description

technical field [0001] The invention relates to the technical field of public transport information processing, and more specifically relates to a data-driven electric bus energy consumption estimation method. Background technique [0002] In recent years, with the accelerating pace of urbanization in my country, the number of motor vehicles has continued to increase, and the energy consumed by motor vehicles and the amount of greenhouse gases emitted are increasing day by day. The contradiction between the environment and motor vehicles has become increasingly prominent, and has become an important contradiction that needs to be resolved urgently in the development of major cities in our country. Compared with other vehicles, public transport vehicles have the advantages of low energy consumption per capita and more environmental protection in terms of energy consumption and greenhouse gas emissions, but public transport vehicles using traditional internal combustion engine...
