Driving working load calculation method of automobile driver

Abstract

The invention discloses a driving working load calculation method of an automobile driver; the driving working load of the driver is represented and obtained by utilizing physiology, psychology and driving behavior of the driver; a driving working load calculation model is built by adopting main task measurement, physiology and psychology measurement, synchronous measurement of a working load self-evaluation system and selection indexes; the method comprises the following steps: a driving working load feature information detection system of the automobile driver is built; a building method of the driving working load calculation model of the automobile driver is built; by adopting the obtained driving working load information and data analysis and selection, the driving working load calculation model of the automobile driver is obtained; electro-cardio indexes are taken as representation indexes of physiology and psychology driving working load measurement; in the invention, the characteristics of the driving behavior of the driver are considered, the accuracy and promptness of the driving working load calculation of the driving working load calculation are improved; in addition, the operational method is simple and provides reference frame for road traffic safety study.

Description

technical field [0001] The method relates to the research of an applied technology, in particular to a method for calculating the driving workload of a car driver, and its achievements are mainly in the field of road traffic safety engineering. technical background [0002] The driver's driving workload refers to the information channel ability to support the work under mental pressure caused by the work tasks and frequency imposed by the road, traffic and environmental conditions on the driver when the driver is driving the vehicle on the road. In recent years, as people pay more and more attention to road traffic safety, the relevant researches have become more and more in-depth. But currently there are mainly the following problems: [0003] There are many measurement techniques for driver's driving workload, mainly including subjective evaluation, main task measurement, secondary task measurement of remaining ability, and biological and psychological measurement. But t...
