Alarming method for fatigue drive of car

Abstract

The invention discloses a fatigue driving alarm method, and belongs to the field of automobile fatigue alarm. The invention takes use of the biological sensing properties that a person is used to firmly hold the steering wheel with both hands in fatigue driving, and that skin resistance of a person increases when the person is fatigued, and combines two monitoring and alarming methods of habitual driving and biological sensing in both time-counting method and number-counting method. Firstly the two electrodes on the steering wheel which are adapted with the two hands of a driver are used for collecting skin resistance of the driver, then existence and increasing of resistance are identified to judge whether the driver is firmly holding the steering wheel with both hands, and to judge increasing rate of the self fatigue degree of the driver, and finally when the period the two hand firmly hold the steering wheel exceeds the required value, the time counter alarms, and when the skin resistance exceeds the upper limit, the number counter alarms. Combination of the two method overcomes shortages of using a single method of high mechanicalness, not-in-time alarm, large influence from the ambient and easily mal-alarm, enables alarming more flexible, more betimes and more accurate, and can be widely used for alarm of various motor-driven vehicles.

Description

technical field [0001] The invention belongs to the field of automobile alarms, and in particular relates to a method for prompting and alarming automobile drivers when fatigue driving occurs during driving. Background technique [0002] Fatigue driving has always been the road killer of human beings. According to related surveys, traffic accidents caused by fatigue driving in Hyundai accounted for 20% of all traffic accidents, and accounted for 40% of serious traffic accidents. These traffic accidents led to There are a lot of property losses and casualties. Therefore, it is an important topic to reduce the incidence of modern traffic accidents to study how to monitor the fatigue degree of vehicle drivers during driving, and to give prompts and alarms in a timely and effective manner. [0003] At present, there are mainly research and development in the following aspects on this issue: 1. Human physiological characteristics: mainly to study the abnormal changes of brain wav...

Problems solved by technology

In general: the bio-sensing monitoring method has the disadvantages that the environment and human personality have a great influence on biological parameters, and it is easy to generate fatigue interference information, thereby reducing the accuracy and practicability of bio-sensing monitoring; the driving habit monitoring method also has human subjective The will will also affect the monitoring of driving habits. Individual differences in driving habits can easily lead to misdiagnosis of fatigue, too mechanical, and untimely alarms, etc.
