Embodiment Construction

[0027] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0028] refer to figure 1 , figure 1 It is a schematic flowchart of an embodiment of the vehicle turning collision warning method of the present invention. In this embodiment, the vehicle collision warning includes:

[0029] Step S10, when the vehicle is in the initial state of turning, obtain the driving information of the vehicle, and obtain the relevant information of the obstacles around the vehicle through the millimeter wave radar and the camera;

[0030] In this embodiment, there is no limit to the way of obtaining the driving information of the vehicle, such as through vehicle sensors, such as speed sensors, positioning sensors, steering wheel angle sensors, cameras, etc. At the same time, the content of the driving information in this embodiment is not limited , for example, may include the driving speed of...

Abstract

The invention discloses an early warning method for collision accidents during turning of a heavy truck. The vehicle is provided with a speed sensor, a steering wheel angle sensor, an information processing module, a radar and a vehicle-mounted camera. The vehicle collision early warning method comprises the following steps: when the vehicle is ready to steer, obtaining turning track information of all wheels of the vehicle through the steering wheel angle sensor and a model algorithm, and obtaining related information of obstacles around the vehicle through the radar and the camera; analyzingwhether the vehicle has a collision risk at a certain moment in the future or not according to the driving information and the related information; and if danger occurs at a certain moment in the future, reminding a driver to avoid collision accidents in a sound-light alarm mode. The vehicle collision early warning is more comprehensive when the vehicle turns and runs, and the accuracy of the vehicle collision early warning and the safety of vehicle running are further improved.

Description

technical field [0001] The invention relates to the field of driving safety, in particular to an early warning method for a collision accident when a heavy truck turns. Background technique [0002] At present, vehicle driving accidents emerge in endlessly, the most important of which is collision accident. Tracing it to its cause is except driver's distraction, road sudden situation, also has a very important reason to be exactly can't send early warning to driver in advance, and then can't deal with in advance to avoid the generation of accident. [0003] At present, there is only a way to judge obstacles ahead by emitting radar waves, but the scope of application of this early warning method is limited, for example, it is only effective for vehicles ahead on the straight lane, and for non-straight lanes, such as crossroads. However, it cannot be accurately judged. At the same time, the accuracy of the existing technology for detecting other roadside obstacles (such as pe...
