Vehicle driving condition prediction method based on working condition characteristics

Abstract

The invention discloses a vehicle driving condition prediction method based on working condition characteristics. The vehicle driving condition prediction method comprises the steps of: performing characteristic parameter extraction of historical condition data of a vehicle, carrying out clustering analysis, and establishing a condition characteristic parameter database; according to the actual working conditions of the vehicle, constructing a relationship between the working condition characteristic data and road and traffic characteristic parameters, and establishing a road and traffic-basedworking condition characteristic parameter prediction model; acquiring road and traffic characteristic parameters of a determined driving route according to the determined driving route, and predicting the working condition characteristic parameters by using the prediction model; and comparing predicted working condition characteristic parameters with the working condition characteristic parameters in the database to obtain the working condition of the driving route to be driven. According to the vehicle driving condition prediction method, the universality and accuracy of the prediction model are ensured through model prediction according to the road and traffic characteristics on the planned route of the vehicle, and meanwhile, the influence of the road and traffic conditions on the vehicle driving state can be reflected.

Description

technical field [0001] The invention relates to a method for predicting vehicle driving conditions, in particular to a method for predicting vehicle driving conditions based on characteristics of working conditions. Background technique [0002] The characteristics of driving conditions are the foundation of vehicle power / energy management. The power / energy control strategies of existing traditional vehicles are mainly designed based on standard driving conditions or instantaneous condition predictions, and more are instantaneous or short-term control of power. It cannot meet the needs of global energy management and has great limitations. [0003] The development of intelligent transportation and Internet of Vehicles technology makes cars driving in road traffic environments become mobile intelligent terminals, and vehicle big data provides the possibility for longer and longer working condition predictions. At present, the prediction of vehicle driving conditions is mainl...
