Rear-end collision prevention system and method used for vehicle

Abstract

The invention discloses a rear-end collision prevention system and method used for a vehicle and relates to the field of vehicle safety. The rear-end collision prevention system used for the vehicle comprises an information collection unit, a control unit and an execution unit. The information collection unit is used for collecting the surrounding information of the vehicle, and the surrounding information comprises the lane line information, the front vehicle information and the rear vehicle information. The control unit is used for receiving and processing the information and sending out an execution instruction when a rear dangerous incoming vehicle is judged. The execution unit is used for reminding a driver of the vehicle and a driver of the rear vehicle after receiving the execution instruction. On the premise of security permission, if the driver of the vehicle has no time to respond, the system spaces out the vehicle and the rear vehicle or enables the vehicle to change a lane to avoid rear-end collision of the rear vehicle. The invention further provides the corresponding method. According to the rear-end collision prevention system and method, through the control unit, the driver is timely reminded of paying attention to safe driving or the vehicle is automatically controlled to accelerate or change the lane, and rear-end collision of the rear vehicle is effectively avoided.

Description

technical field [0001] The present invention relates to the field of vehicle safety, in particular to a rear-end collision prevention system and method for vehicles. Background technique [0002] With the increase in the number of vehicles, the road traffic conditions are becoming more and more complex, and the issue of vehicle safety is increasingly attracting people's attention. [0003] To this end, at present, major vehicle manufacturers have made a lot of efforts in vehicle active safety technology, such as automatic emergency braking system (AEB), forward collision warning system (FCW), etc., which enhance the vehicle's safety to a certain extent. Active safety features. [0004] However, the above-mentioned active safety technology is more concerned with the collision warning between the vehicle and the vehicle in front. For the rear-end collision of the vehicle, the active safety technology cannot give a warning and make a corresponding response. At the same time, b...

Problems solved by technology

[0004] However, the above-mentioned active safety technology is more focused on the collision warning between the self-vehicle and the vehicle in front. For the rear-end collision of the vehicle behind, the active safety technology cannot give a warning and make a corresponding response. Concentrate more attention on the rear of the own car, so it is impossible to respond to the upcoming rear-end collision accident. Therefore, the rear-end collision accident of the rear vehicle greatly increases the probability of traffic accidents
