Embodiment 1
[0083] Embodiment 1, a method for testing and evaluating a driver's dynamic risk perception ability, the specific steps are:
[0084] (1) Classify dynamic risk information;
[0085] (2) Determine the risk levels of different types of dynamic risk information;
[0086] (3) Determine the driving risk comprehensive level of dynamic information in the test road section or area;
[0087] (5) Construct a virtual experimental scene to test driver's risk perception;
[0088] (6) Test the driver's risk perception data through driving simulation experiments;
[0089] (7) Evaluation of driver's perception of dynamic risk information.
[0090] Classify dynamic risk information. Each risk information is composed of one source and one orientation. Sources include motor vehicles, non-motor vehicles, and pedestrians. Risk information is divided into 9 categories in total, and the risk degree of each type of dynamic risk information is different.
[0091] The risk levels of different type...
Embodiment 2
[0107] Embodiment 2, other parts of this embodiment are the same as Embodiment 1, wherein the dynamic risk test scenario is designed as image 3 Shown:
[0108] Two-way 4-lane, with isolation guardrails in the middle. The main vehicle was going straight in the inner lane and met a van in the opposite lane. At this time, a pedestrian crossed the road behind the van and was about to climb over the guardrail.
[0109]Premonitory information: There are many pedestrians on urban roads. Pedestrians appear behind the van and approach the guardrail. Pedestrians may climb over the guardrail. This is the precursory information that the driver of the main vehicle needs to pay attention to.
Embodiment 3
[0110] Embodiment 3, other parts of this embodiment are the same as Embodiment 1, wherein the dynamic risk test scenario is designed as Figure 4 Shown:
[0111] Two-way 4-lane, with a green belt in the middle. The main car was driving normally, and there was an electric car in front of the right side of the main car. After a period of time, the electric car gradually drove from the non-motorized lane to the motorized lane, and finally drove to the opposite side.
[0112] Premonitory information: The electric vehicle is gradually approaching from the non-motorized lane to the motorized lane. At this time, the electric vehicle may occupy the motorized lane or cross the road. This is the precursory information that the driver of the main vehicle needs to pay attention to.

Abstract
The invention relates to a method for testing and evaluating the dynamic risk perception ability of a driver, and belongs to the technical field of driving behavior recognition. The method comprises steps of: (1) classifying dynamic risk information; (2) determining the risk levels of different types of dynamic risk information; (3) determining a driving risk comprehensive level of the dynamic information in a test road segment or area; (5) building a virtual experimental scene for testing the driver risk perception; (6) testing driver risk perception data through a driving simulation experiment; (7) evaluating the driver's dynamic risk information perception. The invention can realize the related technology and method for testing and evaluating the dynamic risk perception ability of the driver to help to test the risk perception ability of the driver, thereby improving the driver's risk cognition ability, improving the driver's safety consciousness, and reducing the likelihood of accidents.
Description
technical field [0001] The invention relates to a method for testing and evaluating a driver's dynamic risk perception ability, and belongs to the technical field of driving behavior recognition. Background technique [0002] Driving a motor vehicle is a complex task that requires a high level of skill from the driver. Completing a driving task not only requires the driver to have good perception and basic control ability, but also requires the driver to have a high risk awareness and the ability to continue to pay attention, flexible coordination, and precise operation, so that it can be completed quickly and safely driving tasks. Among the various skills to ensure safe driving, accurately and effectively discovering dynamic risk information in the driving environment, that is, the driver's ability to perceive dynamic risks, is undoubtedly one of the most important abilities. [0003] Although the driver's ability to perceive dynamic risks is very important, so far there ...
