Problems solved by technology

Although the results of the evaluation method based on the measurement of the driver's physiological parameters are relatively accurate, because they are generally measured before or after driving, they cannot meet the real-time requirements, and the sensors, electrodes or other detection instruments will directly contact the driver during driving. The driver's body will affect the driver's normal driving

Embodiment Construction

[0021] A method for detecting fatigue driving, comprising the following steps:

[0022] (1) Data collection

[0023] Use the driving simulator or actual installation for driving training, collect the vehicle speed V and the steering wheel angle θ in real time according to the cycle T1, and the test subjects conduct a self-assessment of their own fatigue state once according to the cycle T2, and the fatigue state is divided into wakefulness and fatigue;

[0024] (2) Establish fatigue index variable

[0025] The collected vehicle speed V and steering wheel angle θ data are grouped, and the length of each group of data is L, and the following index variables are calculated using the steering wheel angle θ:

[0026] The first variable: the mean square error of the steering wheel angle;

[0027] The second variable: the steering wheel angle crossing area S;

[0028] S = Σ i L | ...

Abstract

The invention discloses a fatigue driving detection method, belonging to the field of safe driving of automobiles. According to the fatigue driving detection method, a fatigue physiological parameter is obtained as a detection index variable by collecting behavioral indicators (mainly including steering wheel data, driving time and driving speed) of a driver and carrying out information preprocessing, a BP (back-propagation) neural network is trained by using the fatigue index variable to establish a corresponding fatigue detection network model, and the fatigue detection is carried out by using the model. According to the fatigue driving detection method, the fatigue of the driver can be objectively and accurately judged on the premise of not influencing the driving operation of the driver by collecting the vehicle data in real time.

Description

technical field [0001] The invention relates to a fatigue driving detection method, which belongs to the field of automobile driving safety. Background technique [0002] With the development of social economy and the improvement of people's living standards, the demand for transportation in the whole society is increasing day by day. The rapid growth of traffic volume has deteriorated road traffic conditions, leading to a series of serious social problems such as traffic safety accidents, environmental pollution, traffic congestion, and economic losses. Especially, major traffic accidents involving passenger vehicles have attracted widespread attention from the society. . Driver fatigue driving is one of the main causes of serious traffic accidents. Statistics show that: the traffic accidents caused by driving fatigue account for about 20% of the total number of accidents, and account for more than 40% of the serious traffic accidents. In my country, there were 2,568 roa...
