Abstract

The invention discloses a driver risk preference behavior diagnosis system. The driver risk preference behavior diagnosis system comprises a scene module, a driving simulator and a diagnosis module, wherein the scene module is used for setting multiple design scenes of a specified task object in a driving task normal form; the driving simulator is used for carrying out simulation driving according to the specified task object; the diagnosis module is used for measuring the decision result, the behavior feature index and vehicle dynamics parameters of a driver under the driving task normal form and evaluating the internal risk preference of the driver according to the measurement result to generate a diagnosis report. The diagnosis system is based on the simulation driving task normal form of a virtual reality technology, the driving simulator serves as an evaluation platform, the internal risk preference of the driver is diagnosed by measuring the driver decision behavior and the vehicle dynamics indexes under the standard driving task normal format, the diagnosis reliability is improved, and the road traffic safety is better ensured.

Description

technical field [0001] The invention relates to the technical field of traffic ergonomics, in particular to a diagnostic system for driver's risk tendency behavior. Background technique [0002] Risky driving behavior reflects the driver's inner intentions and motivations, rather than accidental factors such as observation omissions or operating errors, so it has obvious observable and repeatable characteristics. Current methods for assessing risky driving behavior include subjective assessment and objective measurement. [0003] In the related art, commonly used methods in subjective evaluation are self-assessment questionnaire and sample survey. Among them, the Driver Behavior Questionnaire is the most commonly used scale to predict unsafe driving behavior of drivers and related accidents. It consists of three measurement dimensions: violations, errors and mistakes, and the most relevant to risky driving behavior is the dimension of violations. In addition, other relate...
