Problems solved by technology

The process of lane change and steering actually combines the two behavioral characteristics of longitudinal driving and lateral driving. The current artificial longitudinal / horizontal division method of driving scenes makes it difficult to describe the collision risk of driving and steering with time-space continuous indicators. Therefore, it is necessary to Further exploration and research on the continuous index of driving and steering collision risk in this field

Embodiment Construction

[0067] The specific solutions of the present invention will be further described below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited thereto.

[0068] Such as figure 1 As shown, a driving steering collision warning method includes the following steps:

[0069] Step 1: Construct the road coordinate system and vehicle coordinate system ( figure 2 )

[0070] details as follows:

[0071] Step 1: Take any point on the lane line as the coordinate origin, the direction of the vehicle moving along the lane is the X axis, and the direction 90° from the X axis (rotating counterclockwise) is the Y axis, and establish the road coordinate system [X, Y] , recorded as the global coordinates; the four corner points of any vehicle i are respectively recorded as i 1 i 2 i 3 i 4 , the length of the vehicle is L, the width is W, and the deflection angle between the front and the X axis is (Counterclockwise direction is po...

Abstract

The invention discloses a driving steering collision early warning method. Firstly, a road coordinate system and a vehicle coordinate system describing the position information of a driving vehicle are constructed, then, a collision judgment function of the driving vehicle is defined according to the boundary position relation between the vehicle and the surrounding vehicles, afterwards, in the vehicle coordinate system at the moment t, the risk distribution of collision between the vehicle and the surrounding vehicles in a vehicle steering domain range is calculated at the moment t + tau according to the collision judgement function, the steering angle of the vehicle in the future tau time is predicted, and finally a collision avoidance strategy is formulated according to the collision risk distribution. According to the method in the invention, a driving steering collision risk index which can reflect the real-time change of vehicle track characteristics and has space-time continuityis constructed, and a more accurate collision avoidance scheme is provided for drivers.

Description

technical field [0001] The invention relates to the technical field of traffic safety evaluation and intelligent traffic system active safety, in particular to a driving steering collision warning method. Background technique [0002] Lane changing and steering is the most common driving behavior during road driving. At the same time, due to the complexity of the operation of lane changing and steering, coupled with the inherent limitations of the driver's psychology and physiology (such as blind spots for lane changing, etc.), lane changing and steering are also more dangerous. High vehicle handling behavior. According to the research data of the U.S. Highway Traffic Safety Administration, traffic accidents caused by lane changing process account for as high as 27% of all traffic accidents in statistics. According to a number of research reports, if the driver can realize the risk of accident 0.5s earlier and take corresponding correct measures, it is expected to avoid 50%...
