Problems solved by technology

Among them, the acquisition of driving state information when the driver is in a normal driving state is relatively simple, and the monitoring device can be used to monitor the driving state information of the driver during the driving process; however, the acquisition of driving state information when the driver is in a dangerous driving state It is very difficult, and it is almost impossible to truly realize the dangerous driving state, so the monitoring of driving state information is even more impossible

Embodiment Construction

[0053] Such as figure 1 A method for establishing a driver's driving state identification sample library includes the following steps:

[0054] Step 1. Acquisition of driving state information in normal driving state: Using the driving state information monitoring device 1 and according to the pre-designed monitoring frequency, monitor the driving state information of the vehicle driven by the monitored driver during driving according to the pre-designed route, and synchronously transmit the monitored information to the data processor 2 to obtain driving state information at multiple monitoring moments;

[0055] The driving state information monitoring device 1 includes a steering wheel angle detection unit 1-1 for detecting the steering wheel angle of the driven vehicle and a lateral acceleration detection unit 1-2 for detecting the lateral acceleration of the driven vehicle. The angle detection unit 1-1 and the lateral acceleration detection unit 1-2 are all connected with ...

Abstract

The invention discloses a method for establishing a sample bank for distinguishing driving states of a driver. The method comprises the following steps: I, acquiring driving state information in a normal driving state, namely, monitoring driving state information of a vehicle driven by a monitored driver according to a route designed in advance by using a driving state information monitoring device according to monitoring frequency designed in advance, so as to obtain driving state information of multiple monitoring moments; II, confirming parameters of a vehicle kinetic model; III, acquiring driving state information in a dangerous driving state, namely, generating random numbers, screening the random numbers, acquiring a driver response time array, and acquiring the driving state information; IV, establishing the sample bank. The method disclosed by the invention is simple in step, reasonable in design, convenient to implement and good in use effect, sample information in the dangerous driving state can be acquired by collecting the driving state information in the normal driving state, and the difficulty in acquiring the driving state information in the dangerous driving state can be effectively solved.

Description

technical field [0001] The invention belongs to a method for establishing a sample library, in particular to a method for establishing a sample library for identifying a driver's driving state. Background technique [0002] Traffic accidents on the road are the result of the interaction of factors such as people, vehicles, roads, and the environment, and the driver is the most active factor affecting traffic safety. A traffic accident appears to be an accidental phenomenon on the surface, but in essence it is an instability phenomenon caused by the closed-loop system formed by the driver-vehicle-environment because it cannot respond to the sudden change of working conditions encountered. Through the investigation of a large number of evidence of collision marks and vehicle remains left at the scene of traffic accidents, combined with questionnaire surveys of survivors, researchers from Indiana University in the United States came to the conclusion that about 90% of vicious t...
