Abstract

The invention relates to the field of intelligent driving, and provides a vehicle driving auxiliary device and method. The device can collect an image of a cut-over vehicle when a vehicle enters the vehicle lane from the side part, recognizes the back and the side face of the cut-over vehicle, and detects a base point on the image. The base point is converted into a three-dimensional spatial coordinate system from a plane coordinate system, a three-dimensional image of the cut-over vehicle is built, the cut-over angle and length and width information of the cut-over vehicle are obtained, and according to the vehicle speed, the vehicle driving direction and lane information, whether the vehicle can collide with the back or the side face of the cut-over vehicle or not is judged. According tothe vehicle driving auxiliary device, the back and side face information of the cut-over vehicle can be obtained in a 3D modeling mode, and therefore when the vehicle may collide with the cut-over vehicle, the collision position of the vehicle and the cut-over vehicle can be accurately judged, side collision is avoided, and judgement for the probability of vehicle collision can be more accurate.

Description

Technical field

[0001] The invention relates to the field of intelligent driving, in particular to a vehicle driving assistance device and method. Background technique

[0002] With the development of intelligent driving, driver assistance systems (ADAS) have become more and more widely used. Driver assistance system Lane keeping assist system, automatic parking assist system, brake assist system, reversing assist system and driving assist system are used to assist the driver in driving, make up for the lack of manpower and reduce the occurrence of driving accidents. Among them, adaptive cruise (ACC) and automatic emergency braking (AEB) are two important functions of driver assistance systems (ADAS).

[0003] The adaptive cruise control (ACC) system is based on the traditional cruise control system and evolved from the safe distance keeping system. The radar or camera sensor located in the front of the vehicle detects whether there is a vehicle ahead in the visible range of the ...
