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.
本发明提供了一种车辆危险行为检测方法、装置及系统,涉及智能车辆技术领域。本发明所述的车辆危险行为检测方法,包括:通过路侧感知设备识别标定区域的道路中心线和标定车辆;识别所述标定车辆的行驶方向角,当所述行驶方向角与所述道路中心线的夹角大于预设角度时,确定所述行驶方向角为异常方向角,根据多次确定的所述异常方向角确定所述标定车辆的行驶状态;当所述标定车辆处于异常行驶状态时,向所述标定车辆和/或其他车辆发送告警信息。本发明的技术方案,根据多次确定的异常方向角确定车辆的行驶状态以在车辆处于异常行驶状态时,向标定车辆和/或其他车辆发送告警信息,实现了蛇形等危险行为车辆的提前识别,进而有效提高了行驶安全性。
