Abstract
The host-vehicle-travel-position specification apparatus specifies an estimation error range of map matching reference positions based on relation between a map-matching reference trajectory and an estimation error range of estimated absolute positions. The map-matching reference trajectory is corrected to accord with the estimation error range of map matching reference positions. A vehicle travel position is specified based on the corrected map-matching reference trajectory.
