Embodiment Construction

[0016] The principle and practical application of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0017] figure 1 Be the system composition block diagram of the present invention, among the present invention, processor 1 receives the head video signal from the starting signal in the CAN bus, turning signal, reversing signal, straight signal and video collector 2 collections, and alarm 3 accepts processor 1 Controlling, the memory 4 is used for storing audio and providing cache for the processor 1. The processor 1 judges the running state of the vehicle by using the starting signal, the turning signal, the reversing signal, and the straight-going signal. Video collector 2 collects driver's head video signal, and transmits to processor 1, and processor 1 utilizes these video signals to carry out head tilt recognition to driver, and under starting state or turning lane changing state or reversing state, driver is in When ...

Abstract

The invention aims at providing a driving assistance system based on head slant monitoring. A processor receives a vehicle start signal or a steering signal or a back up signal, receives a head video signal of a driver through a video collector and judges whether the driver is in a state of returning the slant head. When the slant head which needs to return does not return, the processor controls an alerter to alarm, receives a vehicle straight running signal, receives the head video signal of the driver through the video collector and judges whether continuous head slant time of the driver exceeds a preset time. When the continuous head slant time of the driver exceeds the preset time, the processor controls the alerter to alarm.

Description

technical field [0001] The invention belongs to the field of driving assistance, and in particular relates to a driving assistance system based on driver state monitoring. Background technique [0002] Since entering the 21st century, the number of motor vehicles in my country has increased rapidly, and the number of traffic accidents has remained high. Statistics show that driver's negligence and bad driving habits are important reasons for traffic accidents. Therefore, early warning and prompting of the driver's driving behavior will help improve the quality of the driver and reduce traffic accidents caused by improper operation of the driver. At present, in the field of driving assistance, the research and application of driver's driving state monitoring mainly focus on fatigue driving, while there are still relatively few monitoring and prompts for driving behavior, especially driving habits, and there is no way to monitor the driver's head tilt behavior. Monitoring an...
