Vehicle automatic-drive switching device and method based on distracted driving behavior distinguishing

Abstract

The invention discloses a vehicle automatic-drive switching device and method based on distracted driving behavior distinguishing. The device comprises a detection unit and a control unit. The input end of the detection unit is connected with a speed sensor, a three-axis acceleration sensor, a steering wheel turning angle sensor, a steering wheel gripping force sensor, a touch sensor, a ranging sensor, a heart rate sensor, a vehicle data recorder and a GPS. The control unit receives significant variable data and time data of a timer, establishes the relation between vehicle automatic-drive probability dependent variables and distracted driving behavior index independent variables on the basis of a logistic regression model, and works out the vehicle automatic-drive probability. Whether given conditions are met or not is judged through a judging condition I and a judging condition II of a condition judging program, if the judging condition I is met, an automatic early-warning control switch is triggered, and if the judging condition II is met, a vehicle automatic-drive control switch is triggered.

Description

technical field [0001] The invention relates to the field of automotive auxiliary safety electronic equipment, in particular to a vehicle automatic driving switching device and method based on distracted driving behavior discrimination. Background technique [0002] With the rapid development of society and economy, the number of motor vehicles has also increased rapidly, the contradiction between traffic supply and demand has become increasingly prominent, and the traffic pressure is also increasing. Various bad driving behaviors lead to more and more traffic accidents. The behavior of "distracted driving" is particularly prominent. "Distracted driving" includes making calls, playing WeChat, smoking, and picking up things while driving. These behaviors directly cause the driver's perception, reaction and operation ability to decline, and indirectly lead to road Traffic safety and efficiency decline, but these hazards are often ignored by drivers, but they do not know that t...

AI Technical Summary

Problems solved by technology

Mainly use the steering wheel angle as a behavior indicator, integrate vehicle speed, horizontal and vertical acceleration, pedal signals, external environmental information such as road conditions and cross wind, continuous driving time, and the use of the infotainment system in the car to comprehensively judge the driver's current attention state ;Based on some similar studies above, most of them are limited to focusing on the monitoring and identification of distracted driving behaviors, and there are few studies on distracted driving interventions that mainly use control methods to suppress driver distraction or Remind drivers of danger
