具有涉及驾驶员疲劳的预测的安全系统的车辆
摘要：
一种车辆（2），包括：速度记录器（4），其适合于产生包含关于当前时钟时间和所述车辆的运动的时间的信息的速度记录器信号（6）；驾驶员卡片输入单元（8），其适合于产生包含关于驾驶员的驾驶时间和休息时间的信息的驾驶员卡片信号（10）；并且优选地包括用于监控驾驶员活动的监控系统（12），其适合于产生包含关于驾驶员在所述车辆中的活动的信息的警觉信号（14）。该车辆还包括一个或多个驾驶员支持系统（16），例如车道偏离警告系统和自动紧急刹车系统。该车辆还包含包括控制单元（20）和警觉建模单元（22）的安全系统（18），该警觉建模单元（22）适合于使用警觉模型（例如，睡眠/醒来预测器—SWP）基于所述速度记录器信号（6）和/或驾驶员卡片信号（10）来计算驾驶员在预定的未来时间段的当前疲劳值（KSS）和预测疲劳值（KSS），所计算的当前疲劳值和预测疲劳值被配置用于传送到控制单元（20），控制单元（20）适合于基于所述疲劳值来确定用于车辆的驾驶员支持系统（16）的控制信号（24）。
摘要（英）：

A vehicle (2) comprises 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.
