A device and method for real-time observation of the motion attitude of a target vehicle in front when overtaking

Abstract

The invention discloses a device and method for real-time observation of the motion posture of a target vehicle in front when overtaking. The vehicle road information in front is obtained through a visual camera installed in the vehicle body, and the acquired vehicle road information is processed by a digital image processor to obtain the lane. line and the position of the front wheel contact point of the target vehicle in front, the shortest distance from the position of the front wheel contact point of the target vehicle to the lane line is calculated by the data processor, combined with the longitudinal speed and lateral speed of the target vehicle collected by the laser radar, and the distance between the target vehicle and the lane line The real-time distance between the vehicles that are currently overtaking is used to determine the risk level of the current overtaking action, and the early warning indicator installed in the vehicle body provides the driver with an early warning function; the method of the present invention is accurate and efficient, and can monitor the movement of the front target vehicle when overtaking Accurate observation of attitude to improve driving safety.

Description

technical field [0001] The invention relates to the field of active vehicle driving safety, in particular to a real-time observation device and method for the motion posture of a target vehicle in front when overtaking. Background technique [0002] With the rapid development of my country's economy, while the number of cars is increasing year by year, the traffic problems are also very serious. According to the driving style of the driver and the road and traffic environment where the vehicle is located, the driver will often perform reasonable lane change and overtaking actions. In the process of changing lanes and overtaking, even if the road conditions are good, it is much more dangerous than driving in a straight line. This process requires the driver to have higher driving skills and experience. [0003] In the process of changing lanes and overtaking, the driver behind needs to observe the motion posture of the target vehicle that is about to be overtaken in real ti...

Problems solved by technology

When the vehicle is running at high speed, due to the inattention of the driver behind or the lack of effective reference objects, etc., the driving trajectory of the target vehicle in front will be misjudged, especially when the vehicle is overtaking, the target vehicle in front The vehicle accelerates at the same time, or deviates from its driving lane and approaches the own vehicle lane, which will bring a greater risk to the overtaking vehicle of the following vehicle
