Problems solved by technology

The traditional method of camera detection can only detect the front and rear of the vehicle, so the hybrid millimeter-wave radar can obtain the position and width of the vehicle, but cannot calculate the length of the vehicle
Generally, it is judged that the rear of the cutting vehicle enters the current lane for a certain proportion to control the acceleration and deceleration request of the own vehicle. Shorter vehicle, small-angle intrusion effect is better, and large-angle intrusion will cause deceleration delay.
[0005] At present, due to technical limitations, the regulations for AEB generally require rear-end collision prevention, that is, Car To CarRear. For the situation where the vehicle may be hit by the side, it is difficult to do a collision because the traditional method of camera target detection cannot detect the side of the vehicle. protection of

Embodiment 1

[0067] The embodiment of the present invention provides a vehicle driving assistance device, such as figure 1 As shown, the device includes: a self-car state acquisition module, an image acquisition sensor, a cut-in vehicle image processing module, a cut-in vehicle state acquisition module, a lane information acquisition module, and a driver assistance control module.

[0068] The self-vehicle status obtaining module is used to obtain self-vehicle status information, the self-vehicle status information includes vehicle speed information and direction information, the vehicle speed information may be obtained through a wheel speed sensor, and the direction information may be obtained through a steering wheel torque sensor. The image acquisition sensor is used to acquire cut-in vehicle image information, and the image acquisition sensor may be a camera. The cut-in vehicle image processing module is used to convert the cut-in vehicle image information into 3D structure information, a...

Embodiment 2

[0106] A feasible embodiment of the present invention provides a vehicle driving assistance method. Specifically, such as Picture 9 As shown, the vehicle driving assistance method includes:

[0107] S1. When a side vehicle cuts between its own vehicle and the vehicle ahead, collect the cut-in vehicle image information;

[0108] S2. According to the image information of the cut-in vehicle, identify the back and side of the cut-in vehicle, and obtain the back and side information of the cut-in vehicle;

[0109] S3. Perform base point detection according to the rear and side information of the cut-in vehicle, obtain the base point position, and convert the base point position from the plane image to the three-dimensional space, and construct the three-dimensional model of the cut-in vehicle according to the position of the base point in the three-dimensional space ;

[0110] S4. Obtain the state information of the cut-in vehicle according to the three-dimensional model of the cut-in v...

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 ...
