The invention discloses a vehicle driving condition prediction method based on working condition characteristics, which includes extracting characteristic parameters from vehicle historical working condition data, performing cluster analysis, and establishing a working condition characteristic parameter database; According to the relationship between road and traffic characteristic data and road and traffic characteristic parameters, a prediction model of working condition characteristic parameters based on road and traffic is established; according to the determined driving route, the road and traffic characteristic parameters of the route are obtained, and the prediction model is used to predict the working condition characteristic parameters; The predicted working condition characteristic parameters are compared with the working condition characteristic parameters in the database to obtain the working condition of the driving route to be driven. The invention can predict through a model according to the road and traffic characteristics on the planned route of the vehicle, thereby ensuring the universality and accuracy of the prediction model, and simultaneously reflecting the influence of the road and traffic conditions on the driving state of the vehicle.
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...
