Embodiment Construction

[0036] It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention.

[0037] Reference figure 1 , figure 1 It is a schematic flowchart of an embodiment of a vehicle collision warning method of the present invention. In this embodiment, the vehicle collision warning method includes:

[0038] Step S10, when the vehicle is in the driving state, obtain the driving information of the own vehicle, and obtain the driving information of the surrounding vehicles broadcasted by the roadside unit outside the vehicle through the on-board unit, and obtain the related information of the surrounding movement obstacles of the own vehicle through the radar and the camera;

[0039] In this embodiment, there are no restrictions on the way of acquiring the driving information of the vehicle, for example, through on-board sensors, such as speed sensors, positioning sensors, cameras, etc., at the same time, thi...

Abstract

The invention discloses an early warning method for vehicle collision. A vehicle-mounted unit, radar and a camera are arranged on a vehicle. The early warning method for vehicle collision comprises the following steps: acquiring driving information of the vehicle under the driving state of the vehicle; adopting the vehicle-mounted unit for acquiring the driving vehicle information of the surrounding vehicles as broadcast by a road-side unit on the outer side of the vehicle; acquiring related information about the moving barriers surrounding the vehicle by the radar and the camera; analyzing whether the vehicle is in collision risk at present according to the driving information, the driving vehicle information and the related information; and sending out early warning for collision if the vehicle is in collision risk at present. The invention also discloses an early warning device for vehicle collision and an early warning system for vehicle collision. According to the invention, the early warning for vehicle collision is more comprehensive and the accuracy of the early warning for vehicle collision and the driving safety of the vehicle are further increased.

Description

Technical field [0001] The invention relates to the technical field of vehicle driving safety, in particular to a vehicle collision warning method, device and system. Background technique [0002] At present, there is a major type of accident in vehicle driving accidents, which is a collision accident. In addition to the driver’s distraction and road emergencies, there is also a very important reason that the vehicle cannot send the driver in advance. Early warning, which in turn prevents the driver from performing driving safety measures in advance, such as braking, steering, and changing lanes. [0003] In the prior art, there is a way to judge obstacles in front of the vehicle by transmitting radar waves, but the application range of this kind of early warning method is limited, for example, it is only effective for the vehicle ahead on a straight lane, but for non-straight lanes, such as intersections. Lateral oncoming vehicles cannot be accurately detected. At the same time, ...
