Problems solved by technology

However, driving is a complex behavior, and vehicle speed and lateral control ability cannot reflect driving safety most effectively
[0013] In addition, these fragrances regulate and intervene the driver's driving behavior in the form of suprathreshold stimulation, and the stimulation of the smell may bring some other troubles to the driver, such as the driver's uncomfortable and disliked smells that interfere with driving. reaction to

Embodiment 1

[0032] The estrotetraene solution uses propylene glycol as a solvent, and its concentration is 500 μM. In order to verify whether this kind of olfactory stimulation intervention is effective, a driving simulation system is used for verification.

[0033] A group of drivers were divided into an experimental group (using estrotetraene solution) and a control group (using a blank solution, except that no estrotetraene was added, and the remaining components were the same as the experimental group solution).

[0034] Both groups of drivers completed the following task on the driving simulator: the road scene is a two-way lane with a width of 4.8 meters on one side, with double yellow lines in the middle. The total length is 9.9km and consists of 19 curves, 10 of which are left turns and 9 right turns, all of which have the same curvature. The driver needs to follow the vehicle in front and cruise at a constant speed of 20m / s. At this time, the distance from the vehicle in front ...

Embodiment 2

[0041]Taking the estrotetraene solution with a concentration of 100 μM repeated the above experiment, the results showed that the minimum TTC of the experimental group was also significantly higher than that of the control group, indicating that the estrotetraene solution improved the driver's ability to control the distance between cars in the driving behavior, Improved driving safety.

Embodiment 3

[0043] Taking the estrotetraene solution with a concentration of 700 μM repeated the above experiment, the results showed that the minimum TTC of the experimental group was also significantly higher than that of the control group, indicating that the estrotetraene solution improved the driver's ability to control the distance between cars in the driving behavior, Improved driving safety.

[0044] According to common sense, it can be concluded that as the concentration increases, the released estrotetraene will increase, and the estrotetraene solution with a concentration of 500uM and 700uM can improve the driving safety of the driver, so the estrotetraene higher than this concentration The solution also improves the driver's driving safety.

[0045] In practice, TTC indicators can better reflect the driver's driving safety or vehicle distance control ability than basic driving indicators such as vehicle speed and lateral control.

Abstract

The invention discloses a new application of estratetraene, which is used for improving driving safety of a driver. A mode that an estrotetraene solution passes through a subthreshold state is found for the first time, a safety margin of the driver in a driving behavior is improved, and a negative effect brought by suprathreshold olfactory stimulation is reduced.

Description

technical field [0001] The invention relates to the field of vehicle safety driving, and more specifically, relates to a new application of estrotetraene. Background technique [0002] With the continuous development of the transportation industry, traffic accidents have gradually become an important factor causing casualties and property losses. The statistical results of traffic accidents in my country show that accidents caused by drivers account for 74% of traffic accidents, and driver's misoperation has become the main cause of traffic accidents. [0003] The driver's ability to control the distance between vehicles can be judged by the TTC index. The TTC (time tocollision) at a certain moment is the absolute value of the distance between the two vehicles at that moment divided by the speed difference at that moment. TTC is different from simple vehicle speed judgment, but a comprehensive indicator that can truly reflect the driver's driving safety and reflect the driv...
