Method and device for determining collision risk source direction between vehicles, vehicle equipment and vehicle

Abstract

The invention provides a method and a device for determining a collision risk source direction between vehicles, vehicle equipment and a vehicle. The method comprises the steps of performing interaction of position, speed and advancing direction between a current vehicle and a surrounding vehicle; acquiring a connecting line of the current vehicle and the surrounding vehicle according to the positions, speeds and advancing directions of the current vehicle and the surrounding vehicle, and calculating an angle difference between the connecting line of the current vehicle and the surrounding vehicle and the advancing direction of the current vehicle, wherein the connecting line of the current vehicle and the surrounding vehicle takes the current vehicle as the origin; dividing the surrounding 360-degree range of the current vehicle into a plurality of areas; and determining which area around the current vehicle the angle difference between the connecting line of the current vehicle and the surrounding vehicle and the advancing direction of the current vehicle belongs to, i.e., which area the collision risk source direction belongs to. By adopting the method and the device for determining the collision risk source direction between vehicles, the vehicle equipment and the vehicle, early warning of 360-degree risk source direction can be provided for the current vehicle; the efficiency of the algorithm is higher, the execution speed is higher, and the direction determination is more accurate.

Description

technical field [0001] The invention relates to the technical field of digital signal processing, in particular to a method, device, vehicle-mounted equipment and vehicle for determining the direction of a collision risk source in a workshop. Background technique [0002] With the continuous development of the economy, the scale and flow of motor vehicles have increased significantly, and the pressure on urban traffic is increasing. During the driving process of the vehicle, the driver judges whether there is a traffic conflict with the surrounding vehicles by observing the positional relationship between the surrounding vehicles and himself. In order to reduce the driver's misjudgment and reduce the probability of traffic accidents, early warning of vehicle collisions is usually required. [0003] In the prior art, Tongcheng uses radar or video analysis technology for vehicle collision warning. Among them, the radar technology mainly judges the distance by multiplying the...
