The invention discloses a method for preventing traffic accidents caused by doze driving. Comprising a related hardware equipment part for collecting driving states such as the face condition of a driver, a software part for judging sleepiness of the driver, a related control part and the like. The system judges whether the driver is sleepy or not by acquiring whether two or more of five conditions of (1) eye closing time, (2) head-lowering degree, (3) head-lowering and head-raising speed (generally fast and slow head-lowering), (4) blinking frequency (compared with the initial driving stage) and (5) eye opening degree (compared with the initial driving stage) of the driver exceed preset values or not. Wherein (1) is an essential condition, and meanwhile, automatic flameout (normal use of power-assisted steering) or cutting off of a driving power supply or switching to an automatic driving mode or braking can be executed; in addition, voice prompts can be sent out, and the voice prompts can be the voice prompts that the user is dozing off for a meter, the user needs to stop the vehicle for a rest, the engine is about to shut down (or stop driving) after the vehicle is 1 second (or 2 seconds...), a co-driver is required to supervise a driver, the driver is dozing off, or the vehicle is about to enter (or switch to) an automatic driving mode and the like. If the system judges that the driver is sleepy, the engine automatically flames out (or a driving power supply is cut off) or brakes (to a small degree) or is switched to an automatic driving mode after preset time of 1 second or 2 seconds, and emergency measures such as turning right and returning according to road conditions and automatically turning on a right steering lamp or double flashing lamps are taken. And the vehicle can be driven again after a preset time of 20 minutes.
本发明公开了一种防止瞌睡驾驶引起交通事故的一种方法。包括:采集驾驶员面部情况等驾驶状态的相关硬件设备部分,以及判定驾驶员瞌睡的软件部分及相关的控制部分等,驾驶过程中,系统通过获取驾驶员的①眼睛闭合时间②低头程度③低头、抬头的速度(一般是抬头快低头慢)④眨眼的频率(与驾驶初期比较)⑤眼睛睁开的程度(与驾驶初期比较)五个条件中的两个或几个条件是否超过预定值来判断驾驶员是否瞌睡,其中①是必需有的条件,同时可执行自动熄火(转向助力正常使用)或切断驱动电源或切换到自动驾驶模式或刹车制动;另外,可发出语音提示,且语音提示的内容可以是:”你已瞌睡行驶了…米,需要停车休息了,车辆1秒(或2秒…)后发动机即将熄火(或停止行驶)、请副驾驶监督驾驶员,驾驶员已瞌睡”或”车辆即将进入(或切换到)自动驾驶摸式”等语音提示。系统若判断驾驶员已经瞌睡后则1秒或2秒等预定时间后发动机将自动熄火(或切断驱动电源)或制动刹车(小程度)或切换到自动驶模式及根据路况向右转向及回位同时自动打开右转向灯以至双闪灯等应急措施,并且20分钟等预定时间后才能再次行驶等。
