The invention discloses a driver fatigue driving detection device and method. The driver fatigue driving detection device comprises a single-chip microcomputer arranged on a vehicle, a power supply module for supplying power, and a seat cushion pressure sensor and a chair back pressure sensor which are connected with the single-chip microcomputer; a seat position sensor and a steering wheel position sensor are arranged and connected with the single-chip microcomputer. The GPS module of the vehicle is connected with the single-chip microcomputer to obtain a GPS signal of the vehicle; the single-chip microcomputer is connected with the vehicle-mounted controller or the alarm. According to the detection device, a single chip microcomputer is used for calculating and processing signals of a seat pressure sensor and signals of a seat and a steering wheel position sensor so as to confirm whether front and back drivers are the same person or not; and the driving information of the automobile driven by the driver is judged by combining the driving time, the speed and the mileage updated by the GPS module in real time, so that whether the driver is in a fatigue driving state or not can be judged according to the driving time, the mileage and the change of the driving speed on the premise of confirming the same driver.
本发明公开了驾驶员疲劳驾驶检测装置及方法,包括设置在车辆上的单片机,供电的电源模块,座垫压力、椅背压力传感器均与单片机连接;设置座椅位置传感器和方向盘位置传感器,均与单片机连接;车辆的GPS模块与单片机连接,获取的车辆的GPS信号;单片机与车载控制器连接或者与报警器连接。本发明的检测装置,通过单片机对座椅的压力传感器信号,以及座椅和方向盘位置传感器信号进行计算处理,以确认前后驾驶是否是同一人;再结合GPS模块实时更新的驾驶时间、速度和里程来判断驾驶员所驾驶汽车的行驶信息,就可以在确认同一驾驶员的前提下,根据其驾驶时间、里程的长短和驾驶速度的变化来判断出驾驶员是否处于疲劳驾驶的状态中。
