Energy consumption road spectrum analysis method for vehicle cloud cooperative computing

Abstract

The invention discloses an energy consumption road spectrum analysis method for vehicle cloud cooperative computing. The method comprises: collecting vehicle position coordinates and voltage and current values of the vehicle in a certain period; carrying out secondary filtering smoothing on the collected track point coordinates, obtaining road network information in the vehicle running process, and carrying out road network matching on the longitude and latitude information subjected to smoothing processing and the road network information by utilizing a hidden Markov algorithm to obtain matched vehicle running road information; and according to the voltage and the current corresponding to the matched vehicle road network coordinate points, performing integral calculation on time to obtaina vehicle energy consumption road spectrum value. According to the invention, vehicle position coordinate point marks are tightly combined with the real map road network; existing collected positionpoint energy consumption road spectrum information is truly reflected on an automobile driving road network. The obtained energy consumption road spectrum information is more accurate, the road traffic condition and the urban road energy consumption condition can be monitored through analysis of the road energy consumption map, a basis is provided for urban road planning and construction and public transport development, and energy conservation and emission reduction of cities are helped to be achieved.

Description

technical field [0001] The invention belongs to the field of transportation, in particular to an energy consumption road spectrum analysis method for vehicle-cloud collaborative computing. Background technique [0002] As environmental issues are getting more and more attention, electric vehicles have become an important part of future green transportation. In recent years, countries have introduced a series of policies to promote the development of electric vehicles. The main purpose of promoting electric vehicles is to achieve energy saving and emission reduction in the transportation field, but there are still obvious deficiencies in the evaluation method of the energy consumption of electric vehicles. At present, the test and evaluation conclusions of electric vehicle energy consumption cannot be used to accurately predict the energy consumption of electric vehicles in actual driving. The driving energy consumption of electric vehicles not only directly determines the ...

Problems solved by technology

[0003] The existing research methods mainly mark the energy consumption value of the vehicle through GPS coordinate points, and then display it on the map. The vehicle location information may be inaccurate, and the distance between sampling points is too large, which makes the vehicle energy consumption road spectrum information obtained inaccurate. In some cases where GPS sampling is lost, there may be a problem that the vehicle energy consumption road spectrum information cannot be obtained. question
