Problems solved by technology
Unable to make accurate judgments on the driver's driving status and driving intentions, resulting in many situations that do not require warnings, but alarms are issued. Too many false warning signals may interfere with the driver's normal driving
On the other hand, due to the high noise in the driving process of the vehicle, only sound warnings may not arouse the driver's vigilance

The invention relates to a lane departure early warning system based on the driving state and the road condition information. The lane departure early warning system comprises a front camera, a left side rearview mirror camera, a right side rearview mirror camera, a fatigue monitoring camera, a lane departure early warning system controller, an audible alarm, a small-size vibrating motor, a vehicle turning CAN bus and a display screen. The invention further discloses an early warning method of the lane departure early warning system based on the driving state and the road condition information. According to the lane departure early warning system, the fatigue monitoring camera monitors the fatigue state of a driver in real time to more precisely judge whether the lane departure of a vehicle is caused by fatigue of the driver; the left side rearview mirror camera and the right side rearview mirror camera obtain the road condition information of the rear side when the vehicle departuresthe lane to prevent the vehicle from side collision after lane departure; according to the driving state of the driver and the road condition information, the danger level of the vehicle driving is comprehensively determined to carry out audible alarm or seat vibration alarm, so that the driver is more vigilant to the lane departure, and the driving safety is ensured.
Description
technical field [0001] The invention relates to the technical field of advanced vehicle driving assistance, in particular to a method for a lane departure warning system based on driving state and road condition information. Background technique [0002] With the rapid development of automobile technology and artificial intelligence, consumers have higher and higher requirements for the safety and intelligence of automobiles. A series of advanced auxiliary driving technologies have been applied to modern automobiles, and the lane departure warning system is one of them. one. However, the existing lane departure warning system generally adopts a technical solution of a forward-facing camera and a buzzer, and only provides sound alarm information to the driver according to the lane line in front of the vehicle and the position information of the vehicle. It is impossible to make accurate judgments on the driver's driving state and driving intention, resulting in many situatio...
