Driver energy saving evaluation method and system

Abstract

The invention particularly relates to a driver energy saving evaluation method. The method comprises the following steps of: firstly dividing a vehicle running route into at least one kinematic fragment, and generating a running condition type of each kinematic fragment through a preset running condition classification model; generating an energy saving grade of each kinematic fragment according to energy saving degree evaluation models corresponding to different running condition types; and finally generating a driver energy saving evaluation score of the vehicle running route according to the energy saving grades of all the kinematic fragments and a preset score of each energy saving grade. According to the method, the kinematic fragments are taken as basic units for the energy saving evaluation of drivers, and through recognizing the running condition types of the kinematic fragments, the influences, on the energy saving driving evaluation, of road traffic conditions can be lightened so that universality is provided. Meanwhile, the method is capable of automatically selecting energy saving degree evaluation models with best effect to generate energy saving grades according to the running condition types, so as to quantifying the energy saving driving levels of drivers more objectively and reasonably.

Description

technical field [0001] The invention relates to the field of driver driving level evaluation, in particular to a method and system for driver energy saving evaluation. Background technique [0002] The driver's driving operation directly affects the fuel consumption of the vehicle. Even for a professional driver, different driving operation methods will lead to differences in the fuel consumption of the vehicle. The research, popularization and application of driver energy saving evaluation methods have very important practical significance for the automotive industry to achieve the goal of energy saving and emission reduction. At present, the commonly used method to evaluate the driver's energy efficiency ignores the impact of vehicle driving conditions on the evaluation results, and the fuel consumption of a driving trip is not only affected by driving behavior, but also by traffic flow. In order to eliminate this effect, some researches are conducted on selected road sec...
