    • A vehicle (2) comprising a tachograph (4) adapted to generate a tachograph signal (6) containing information about current clock time and the times of the vehicle's movements, a driver's card input unit (8) adapted to generate a driver's card signal (10) containing information about driving and rest times for the driver, and preferably a monitoring system(12) for monitoring of driver activity which is adapted to generate an alertness signal (14) containing information about the driver's activity in the vehicle. The vehicle further comprises one or more driver support systems (16), e.g. a Lane Departure Warning system and an Automatic Emergency Brake system. The vehicle also comprises a safety system(18) comprising a control unit (20) and an alertness modelling unit (22) adapted to calculate a current tiredness value (KSS) and predicted tiredness values(KSS) for the driver over a predetermined future period of time, using an alertness model (e.g. sleep/wake predictor –SWP), based on said tachograph signal (6) and/or driver's card signal(10) and preferablysaid alertness signal (14), said calculated current and predicted tiredness values being arranged for conveying to said control unit (20) which is adapted to determine control signals (24) for the vehicle's driver support systems on the basis of said tiredness values.
    • 车辆(2)具有行驶记录仪(4),其产生包含关于当前时钟时间和车辆运动次数的信息的行车记录器信号(6),驾驶员报告输入单元(8)生成包含关于 驾驶员和休息时间,包括监视(12)驾驶员活动,其产生警告信号(14),其包含关于驾驶员在车辆中的活动的信息。 安全系统(18)具有控制单元(20)和警报性建模单元(22),其根据行车记录仪信号(6)和/或驾驶者报告计算驾驶员的当前和预测疲劳值(KSS) 信号(10)。 将疲劳值传送到控制单元,该控制单元确定用于车辆驾驶员支撑系统的控制信号(24)。
