The invention provides a driving takeover reminding device and method based on video recognition and a steering wheel sensor. The device comprises a touch sensor, an infrared camera, a vibration reminding device, a first processing unit and a second processing unit. The infrared camera obtains a face image of a driver in real time, and the first processing unit analyzes the image collected by theinfrared camera and judges whether the driver is in a fatigue state or not. The touch sensor detects time when the hands of the driver are separated from the steering wheel, and the second processingunit judges whether the driver is in an abnormal driving state or not according to the detected time when the hands of the driver are separated from the steering wheel. When the driver is in the fatigue state and/or the time when the driver is in the abnormal driving state exceeds a set safety time threshold value, a vibration reminding device is triggered, and a driving takeover request is sent out. Traffic accidents caused by distraction or nap of the driver are avoided, the safety of the driver is improved, and an occurrence probability of the traffic accidents is reduced.
本发明提供一种基于视频识别与方向盘感应器的驾驶接管提醒装置及方法。本发明装置,包括:触觉感应器、红外摄像头、震动提醒装置、第一处理单元和第二处理单元。红外摄像头实时获取驾驶员的面部图像,第一处理单元对红外摄像头采集到的图像进行分析,判断驾驶员是否处于疲劳状态。触觉感应器检测驾驶员的双手脱离方向盘的时间,第二处理单元根据检测的驾驶员双手脱离转向盘的时间判断驾驶员是否处于非正常驾驶状态。当驾驶员处于疲劳状态,和/或驾驶员处于非正常驾驶状态的时间超过设定的安全时间阈值,则触发震动提醒装置,发出驾驶接管请求。避免由于驾驶员走神或打盹发生交通事故,提高了驾驶员的安全性,降低了交通事故的发生概率。
