Rear-end collision avoidance system and method

Abstract

The invention discloses a rear vehicle rear-end collision avoidance system and method, the system comprises a rear vehicle collision early warning system and a rear vehicle rear-end collision avoidance system, the rear vehicle collision early warning system is used for estimating the collision time according to the motion state of a rear vehicle target, and determining the alarm level according to the collision time; and the rear vehicle rear-end collision avoidance system is used for controlling the vehicle to avoid the rear vehicle according to the alarm level and the driving environment of the vehicle determined by the rear vehicle collision early warning system. According to the rear-end collision avoidance system for the rear vehicle, the motion state of the vehicle behind the vehicle is accurately recognized at night and in severe weather, and early warning of the motion state of the vehicle behind the vehicle is achieved according to the estimated collision time; through the obtained early warning level information, active avoidance of the vehicle is achieved, a driver can be assisted in driving more safely, and traffic accidents caused by rear-end collision of rear vehicles can be avoided.

Description

technical field [0001] The invention relates to the technical field of automatic driving, in particular to a rear-end collision avoidance system and method. Background technique [0002] With the continuous development of science and technology, the clothing, food, housing and transportation of contemporary people are getting closer to the direction of intelligence. Cars, as the main means of transportation for contemporary people, are becoming increasingly intelligent. Intelligent systems such as active safety and passive safety of vehicles are constantly being upgraded. In recent years, various ADAS functions, such as automatic emergency braking (AEB), adaptive cruise system (ACC), lane keeping system ( LKA) and other systems, although the development of these systems can avoid the collision between the vehicle in front and the vehicle in front, but the vehicle cannot avoid being rear-ended. [0003] When the car is running, the driver usually judges the distance between ...

Problems solved by technology

[0002]With the continuous development of science and technology, the basic necessities of life of contemporary people are becoming more and more intelligent. Intelligent systems such as active safety and passive safety have been continuously upgraded, from the standard anti-lock braking system (ABS) and electronic stability control system (ESP) of vehicles to various ADAS functions in recent years, such as automatic emergency braking ( AEB), Adaptive Cruise Control (ACC), Lane Keeping System (LKA) and other systems, although the development of these systems can avoid the collision between the vehicle in front and the vehicle in front, but the vehicle cannot avoid being rear-ended

[0003] During the driving process of the car, the driver usually judges the distance between the vehicle behind and the vehicle through the interior and exterior rearview mirrors, but at night and in severe weather scenes , the driver may not be able to correctly judge
