The invention is suitable for the technical field of driving assistance, and particularly relates to a contact type driver driving fatigue real-time monitoring device and method, and the method comprises the steps: obtaining seat pressure data and steering wheel pressure data; calculating the pressing area of the steering wheel according to the pressure data of the steering wheel, counting the pressure value of each point in the pressing surface, and drawing a corresponding steering wheel pressure curve; acquiring a seat model, determining a pressure value of each point on the seat model according to the seat pressure data, and drawing a seat pressure curve corresponding to each point; the steering wheel pressure curve and the seat pressure curve are analyzed, and whether driving fatigue exists or not is judged. The pressure sensors are arranged on the steering wheel and the seat, so that changes of hand pressure and back pressure of a driver are recognized, whether a user is in driving fatigue or not is judged according to the pressure changes, real-time monitoring on the driver is achieved, prompting is conducted when fatigue occurs, and driving safety is guaranteed.

    本发明适用于驾驶辅助技术领域,尤其涉及一种接触式驾驶员驾驶疲劳实时监控装置及方法,所述方法包括:获取座椅压力数据和方向盘压力数据;根据方向盘压力数据计算方向盘按压面积,并统计按压面内各点的压力值,绘制对应的方向盘压力曲线;获取座椅模型,根据座椅压力数据确定座椅模型上各点的压力值,绘制各点对应的座椅压力曲线;对方向盘压力曲线和座椅压力曲线进行分析,判定是否存在驾驶疲劳。本发明通过在方向盘和座椅上设置压力传感器,从而识别驾驶人员的手部压力和背部压力变化,根据压力变化判定用户是否存在驾驶疲劳的情况,以实现对驾驶者的实时监控,在出现疲劳时进行提示,保证了行车安全性。
