A vehicle driving economy evaluation system and evaluation method

Abstract

The invention relates to a vehicle driving economy evaluation system and a vehicle driving economy evaluation method. The vehicle driving economy evaluation system is characterized by comprising a data center and a plurality of vehicular terminals; the data center exchanges information with the vehicular terminals through wireless network communication technology; the data center comprises an archive data storage module and an evaluation model correction module; each of the vehicular terminal comprises a mode command acquisition module, an archive data acquisition module, a running data acquisition module composed of a GPS (global positioning system)navigation installation and a car recorder, an desired fuel consumption prediction module, an evaluation parameter storage module, a driving behavior evaluation module and a driving suggestion output module. The vehicle driving economy evaluation method includes acquiring various data needed for evaluation firstly, calculating to obtain a corresponding score through the desired fuel consumption prediction module and the driving behavior evaluation module and outputting the score to the driving suggestion output module to display, and storing various data of drivers to the data center for model correcting and training. The vehicle driving economy evaluation system and the vehicle driving economy evaluation method can be applied to driving economy evaluation of various road conditions and vehicle models.

Description

technical field [0001] The invention relates to a vehicle driving economy evaluation system and evaluation method, in particular to a vehicle driving economy evaluation system and evaluation method based on Internet of Vehicles. Background technique [0002] The fuel economy of a vehicle is related to many factors, among which, the driver's driving behavior has a great impact on fuel consumption, and reasonable driving behavior is conducive to saving energy and protecting the environment. For commercial vehicles, urging and assisting drivers to adopt reasonable driving behavior is beneficial to reduce fuel consumption, improve the transportation efficiency of enterprises, and reduce operating costs; for ordinary car owners, understanding the rationality and scientificity of driving behavior can guide driving Drivers can improve their driving skills and reduce the cost of using cars. Many driving evaluation systems have been developed at home and abroad, such as the "driver ...

AI Technical Summary

Problems solved by technology

[0003] The existing problems in the current evaluation system and method are as follows: 1. The evaluation of driving economy is carried out by pre-stored evaluation weights and parameters, the accuracy is limited, and it lacks the ability to perform real-time dynamic changes according to the road environment and vehicle status

2. The weights and thresholds used are artificially specified, which is subjective, which is not conducive to the accuracy and objectivity of the evaluation method, and limits the possibility of improving economical driving behavior

3. The factors considered are not comprehensive, most of the investigations on drivers are limited to the speed control, and the driving suggestions are not very targeted

4. It can only make evaluations and suggestions for road sections that have been recorded, and cannot make suggestions for road sections that have not been driven, which lacks versatility
