Problems solved by technology
[0003] Collision warning technology is becoming more and more popular, but the current collision warning technology on the market is aimed at front collision warning, and the detection equipment is installed in front of the vehicle to monitor the relative distance between the vehicle and the vehicle in front and the speed of the vehicle at all times. , the automatic alarm reminds the driver to brake, but seldom considers the early warning method of the rear vehicle hitting our vehicle because the driver did not notice our vehicle or other reasons

The invention provides a vehicle rear-end collision emergency avoidance method, system and equipment and a storage medium. The method comprises steps as follows: the relative distance and the relativespeed between a vehicle and a rear vehicle are acquired, and a lateral driving speed of the rear vehicle is acquired; when the lateral driving speed of the rear vehicle is smaller than a preset speedthreshold value, predicated collision time of the vehicle with the rear vehicle is smaller than a preset time threshold value and adjacent vehicles exist on two adjacent side lanes in the first preset distance of a front lane of the vehicle, the vehicle performs information interaction with the adjacent vehicle with the maximum distance to the front vehicle in the front two adjacent side lanes, aselected adjacent vehicle is accelerated to vacate an avoidance area to allow the vehicle to drive by changing the lane, or the vehicle changes the lane to the vacant adjacent lane on one side with low contact ratio with the rear vehicle, or the vehicle changes the lane to the adjacent lane on one side where no adjacent vehicle exists in the front two adjacent side lanes. Safe active lane changeoperation can be performed timely, and life and property safety of passengers in a vehicle is protected.
Description
technical field [0001] The invention relates to the field of driving control, in particular to a method, system, equipment and storage medium for emergency avoidance of vehicle rear collision. Background technique [0002] Self-driving vehicles (Autonomous vehicles; Self-driving automobile), also known as unmanned vehicles, computer-driven vehicles, or wheeled mobile robots, are intelligent vehicles that realize unmanned driving through computer systems. Self-driving cars rely on artificial intelligence, visual computing, radar, monitoring devices, and global positioning systems to work together to allow computers to automatically and safely operate motor vehicles without any active human intervention. [0003] Collision warning technology is becoming more and more popular, but the current collision warning technology on the market is aimed at front collision warning, and the detection equipment is installed in front of the vehicle to monitor the relative distance between th...
