Abstract
The vigilance process includes receiving inputs of operator activity and determining the presence or absence of activity inputs during a first delay period. The operator is warned, if activity inputs are absent during the first period. If the warning period expires before being cancelled, a vigilance penalty signal is produced. The brakes are applied for a first predetermined period in response to the vigilance penalty signal.
