Abstract
Method and arrangement for determining inattentiveness of an operator of a vehicle includes determining the position of the vehicle, analyzing the determining position of the vehicle relative to a map, monitoring motion of the vehicle relative to the map to determine whether the vehicle is deviating from the map, and providing a warning when the monitored motion of the vehicle deviates from normal motion or operation of the vehicle. The position of the vehicle may be determined using a satellite-based positioning system and an inertial measurement unit (IMU). The IMU may be a MEMS-packaged IMU integrated with the satellite-based positioning systems.
