Electric automobile driving feedback system based on combination of driving data and map prediction

Abstract

The invention relates to an electric automobile driving feedback system based on combination of driving data and map prediction. The electric automobile driving feedback system comprises a vehicle sensor for acquiring the real-time information of a vehicle, a vehicle-mounted map navigation system, a data transmission treatment and real-time calculating system, and a driving feedback display system, wherein the vehicle-mounted map navigation system is combined with satellite positioning to plan and navigate the vehicle driving route and inquiry the information of a nearby charging station; thedata transmission treatment and real-time calculating system is used for analyzing the vehicle real-time information, combining with the preset program to calculate the rest SOC of a battery, the driving distance of unit energy and the rest driving distance, and the 100km energy consumption under the current vehicle condition, counting the times of sudden stop and sudden starting during the driving process of the vehicle, and analyzing the driving style; and the driving feedback display system is used for displaying the feedback information of the vehicle-mounted map navigation system and thedata transmission treatment and real-time calculating system. The electric automobile driving feedback system can provide practical information including charging reminding, charging caution, the nearest charging station recommendation, real-time endurance mileage estimation and recommended charging duration for the driver intuitively and timely, displays a friendly and humanized interface and improves the driving experience of the user.

Description

technical field [0001] The invention belongs to the field of automobiles, and in particular relates to an electric vehicle driving feedback system based on the combination of driving data and map prediction. Background technique [0002] Pure electric vehicles use green and environmentally friendly electric energy, have the remarkable advantages of zero emission and no pollution, and are the main direction of development in the field of new energy vehicles. However, in the survey and analysis of consumers' attitudes towards electric vehicles, the biggest concern of consumers for electric vehicles is the mileage of the battery, and the factors such as the backward construction of charging facilities, high cost, and the safety of power battery thermal management cannot meet the needs of consumers. The mileage required by consumers and the low space coverage of charging piles are the main problems currently faced by pure electric vehicles. The mileage anxiety of pure electric ...
