The invention discloses a driving behavior detection method and device. The method comprises the steps: acquiring current road traffic state information, vehicle state information and driver state information; carrying out danger level standardization processing on the information to obtain a corresponding road traffic state vector, a vehicle state vector and a driver state vector; determining a current road traffic state dangerous driving index, a vehicle state dangerous driving index and a driver state dangerous driving index by utilizing the vectors and the corresponding dangerous driving judgment matrix; determining a current dangerous driving comprehensive index by utilizing the dangerous driving indexes and a preset dangerous driving comprehensive judgment matrix; according to the dangerous driving comprehensive index and a preset early warning threshold, judging whether an alarm is needed currently, and executing a corresponding alarm process when the alarm is needed. Accordingto the method disclosed in the invention, the accuracy of identifying dangerous driving and giving an alarm can be improved.
本申请公开了一种驾驶行为检测方法和设备,其中方法包括:获取当前的道路交通状态信息、车辆状态信息和驾驶员状态信息;并对这些信息进行危险等级标准化处理,得到相应的道路交通状态向量、车辆状态向量和驾驶员状态向量;利用这些向量和相应的危险驾驶判断矩阵,确定出当前的道路交通状态危险驾驶指数、车辆状态危险驾驶指数和驾驶员状态危险驾驶指数;利用这些危险驾驶指数和预设的危险驾驶综合判断矩阵,确定当前的危险驾驶综合指数;最后,根据所述危险驾驶综合指数和预设的预警阈值,判断当前是否需要报警,并在需要时执行相应的报警过程。采用本发明,可以提高对危险驾驶进行识别并报警的准确度。
