Seat device of a vehicle, method of controlling the seat device and computer program product therefor

摘要

An egress-start determining device ( 22, 31 ) determines a start of egress of a passenger seated in a seat of a vehicle. A completion determining device ( 9, 34 ) determines completion of a driver's head moving out of a door opening of the vehicle after the start of egress of the passenger. A seat-sitting-face position adjusting device ( 36, 37, 38, 16f, 16r ) adjusts a position of a sitting face of the seat in such a manner that the position is adjusted to a first position during a time from the start of egress of the passenger to the completion of the driver's head moving out of the door opening of the vehicle, and the position is adjusted to a second position after the completion of the driver's head moving out of the door opening of the vehicle.
