The invention discloses an early warning method and early warning device based on a driving distraction state. The early warning method comprises the following steps: step one, acquiring traffic conditions and road conditions around a vehicle and identifying a driving behavior of a driver; step two, judging whether a distracted driving behavior exists or not according to the driver behavior, and if not, entering step three; if so, entering step 4; step three, judging whether the vehicle deviates from the lane or not based on the traffic conditions around the vehicle and the road conditions, ifnot, not sending out early warning and ending the early warning; if so, prompting the driver by voices, and ending the early warning after the prompt is finished; and step four, predicting an impending collision type and a lane deviation situation, and carrying out early warning of a corresponding level based on the predicted situation. According to the early warning device and the early warningmethod based on the driving distraction state, the risk level of the current driving behavior is judged based on the driving state of the driver, the driving environment and the vehicle attitude information and early warning can be performed according to the response state of the driver, so that traffic accidents are avoided.
本发明公开了一种基于驾驶分心状态的预警方法及预警装置,包括以下步骤:1)获取车辆周围交通状况和道路状况并识别驾驶员的驾驶行为;2)根据驾驶员行为判断是否存在分心驾驶行为,若无,则进入3);若有,则进入步骤4);3)基于车辆周围交通状况和道路状况判断是否偏离车道,若不偏离,不发出预警,结束本轮预警;若偏离,语音提示驾驶员,提示结束后结束本轮预警;4)预测即将发生的碰撞类型和车道偏离情况,基于预测的情况进行相应级别的预警。本发明的基于驾驶分心状态的预警装置及预警方法,基于驾驶员驾驶状态、驾驶环境和车辆姿态信息,判断当前驾驶行为的风险等级,并可根据驾驶员反应状态进行预警,避免交通事故发生。
