Problems solved by technology

The existing technology mainly has the following disadvantages: relying on the on-board sensor, it can only identify the dangerous behavior of the vehicle in front, but cannot identify the dangerous behavior vehicle on the long driving route ahead; and there is a blind spot problem, such as when turning at an intersection, the Due to physical occlusion, it is impossible to identify dangerous behaviors of vehicles behind corners by only installing sensors on the vehicle

Embodiment Construction

[0025] In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0026] Such as figure 1 As shown, the embodiment of the present invention provides a vehicle dangerous behavior detection method, including: identifying the centerline of the road in the marked area and the marked vehicle through the roadside sensing device; identifying the driving direction angle of the marked vehicle, when the driving direction angle When the included angle with the center line of the road is greater than a preset angle, it is determined that the driving direction angle is an abnormal direction angle, and the driving state of the calibration vehicle is determined according to the abnormal direction angle determined multiple times; when the calibration vehicle When in an abnormal driving state, send warning information to...

Abstract

The invention provides a vehicle dangerous behavior detection method, device and system, and relates to the technical field of intelligent vehicles. The vehicle dangerous behavior detection method comprises the following steps: a road center line of a calibration area and a calibration vehicle are identified through roadside sensing equipment; the driving direction angle of the calibrated vehicle is recognized, when the included angle between the driving direction angle and the road center line is larger than a preset angle, the driving direction angle is determined to be an abnormal direction angle, and the driving state of the calibrated vehicle is determined according to the abnormal direction angle determined multiple times; and when the calibrated vehicle is in the abnormal driving state, alarm information is sent to the calibrated vehicle and / or other vehicles. According to the technical scheme, the driving state of the vehicle is determined according to the abnormal direction angles determined for multiple times, when the vehicle is in the abnormal driving state, the warning information is sent to the calibrated vehicle and / or other vehicles, advanced recognition of vehicles with dangerous behaviors such as snakelike behaviors is achieved, and then the driving safety is effectively improved.

Description

technical field [0001] The present invention relates to the technical field of intelligent vehicles, in particular to a method, device and system for detecting dangerous vehicle behaviors. Background technique [0002] At present, there are mainly the following methods for identifying dangerous behaviors of vehicles: Identifying dangerous behaviors of the vehicle itself: judging whether the vehicle is snaking according to the vehicle’s own data such as the steering wheel and wheel angle; Dangerous behaviors such as snaking, rapid deceleration, and too close a distance between vehicles. The existing technology mainly has the following disadvantages: relying on the on-board sensor, it can only identify the dangerous behavior of the vehicle in front, but cannot identify the dangerous behavior vehicle on the long driving route ahead; and there is a blind spot problem, such as when turning at an intersection, the Due to physical occlusion, it is impossible to identify dangerous ...
