Fordon med ett säkerhetssystem med prediktion av förartrötthet

摘要

A vehicle (2) has a tachograph (4) which generates a tachograph signal (6) containing information about current clock time and the times of the vehicle's movements, a driver's report input unit (8) generates a signal (10) containing information about driving and rest times for the driver, including monitoring (12) of driver activity which generates an alertness signal (14) containing information about the driver's activity in the vehicle. A safety system (18) has a control unit (20) and an alertness modelling unit (22) which calculates a current and a predicted tiredness values (KSS) for the driver based on the tachograph signal (6) and/or the driver's report signal (10). The tiredness values are conveyed to a control unit which determines control signals (24) for the vehicle's driver support systems.
