The invention discloses a dangerous driving identification method for making up for the deficiency of an L2-level auxiliary driving system, and the method comprises the steps: S1, judging whether a vehicle is in a fatigue driving state or not when the vehicle is in L2-level auxiliary driving; s2, when it is detected that the driver is in the fatigue driving state, whether a vehicle exists in front of the side of the vehicle or not is recognized; s3, recording the vehicle in front of the right side of the own vehicle as a target vehicle, and calculating the meeting time T of the own vehicle and the target vehicle; s4, identifying and judging whether the right-side dotted lane line of the vehicle is shielded or not; s5, according to the identified condition that the target vehicle shields the lane line, judging whether the L2-level auxiliary driving system can identify that danger exists in front of the vehicle or not; and S6, when the L2-level auxiliary driving system does not recognize that the danger exists in front of the vehicle, the driver needs to be awakened to take over driving. According to the dangerous driving recognition method, whether the L2-level auxiliary driving system recognizes a dangerous phenomenon within a certain time or not can be judged, and when the L2-level auxiliary driving system does not recognize the dangerous phenomenon, a driver is awakened to take over the vehicle smoothly, and collision is avoided.

    本发明公开了一种弥补L2级辅助驾驶系统不足的危险驾驶识别方法,包括步骤:S1.当自车处于L2级辅助驾驶时,判断其是否处于疲劳驾驶状态;S2.当检测到驾驶人属于疲劳驾驶状态时,识别自车侧前方是否存在车辆;S3.将处于自车右侧前方的车辆记为目标车辆,计算自车与目标车辆的相遇时间T;S4.识别并判断自车的右侧虚线车道线是否被遮挡;S5.根据识别出的目标车辆遮挡车道线的情况判断L2级辅助驾驶系统是否能识别出自车前方存在危险;S6.当L2级辅助驾驶系统未识别出自车前方存在危险时,需唤醒驾驶人接管驾驶。本发明的危险驾驶识别方法可以判断L2级辅助驾驶系统是否在一定时间内识别到危险现象,当未识别出危险时,唤醒驾驶人顺利接管车辆,避免碰撞。
