Method and arrangement for controlling a subsystem of a vehicle dependent upon a sensed level of driver inattentiveness to vehicle driving tasks. A variable characteristic is measured, on a substantially real-time basis, which correlates to the driver's inattentiveness. The level of inattentiveness is assessed based at least in part on the measurement. The performance of a subsystem of the vehicle, such as cruise control or lane keeping support, is tailored, based thereupon, to assure that behavior of the vehicle appropriately matches the driver's present level of inattentiveness. The subsystem's operation is controlled in an effort to avoid or prevent the establishment of driving conditions that become inherently more dangerous as the driver's level of inattentiveness increases.
A method for assessing a traveling vehicle driver's level of inattentiveness caused by excessive workload due to the driver's performance of secondary tasks and responsively adapting a vehicle motion control subsystem based thereupon, said method comprising:
The method as recited in 1, further comprising determining that the driver's level of inattentiveness is outside a safety range, and informing the driver that the safety range has been exceeded.
A method for assessing a traveling vehicle driver's level of inattentiveness caused by excessive distraction due to the driver's performance of secondary tasks and responsively adapting a vehicle motion control subsystem based thereupon, said method comprising:
The method as recited in 30, further comprising determining that the driver's level of inattentiveness is outside a safety range, and informing the driver that the safety range has been exceeded.
