Automation Control System against Driver Falling Asleep in Traffic

摘要

The paper is devoted to the development of a new automation recognition and warning system against driver falling asleep in traffic. The issue of the physical condition of professional drivers on the trip is considered on the part of both efficiency and quality of determination, and in terms of improving overall road safety. The existing and widely used devices for determining the transition to the sleep phase of behind at the wheel drivers are analyzed. Their advantages and disadvantages are detected. It has been established that the main negative factor preventing the mass introduction of pre-existing warning systems is the need to put on one or another monitoring device before starting the movement. The carried out design and research work offers a comprehensive monitoring of the physical and physiological state of a person at the wheel as a new way of preventing his falling asleep during the movement. The variants of algorithmic implementation are proposed for consideration can be applied in freight and passenger long-distance vehicles. Two contrasting options of the automatic control status of the driver physical condition are considered. The first approach proposes the use of sensors of the biometric parameters of the body, pulse, body temperature, and hands on the wheel pressure sensors. The second is using tracking cameras-detectors. Both for the first and the second versions of the automation system, a toolset of control devices installed Inside the vehicle and have no physical, so irritating action on the driver. A software approach to eliminate false positives of the proposed devices is developed. The paper considered the flow diagrams of the automatic systems and a logical structure of analysis and decision-making. A set of Impacts intended for driver's awakening is proposed. A conclusion is made about the technical prospects of the proposed approach to the design of automated systems.
