Abstract
A vehicular operation processing system has a memory card for storing coordinates of a plurality of check point sets, each of which is composed of a set of check points, and an ECU for, when determining that a vehicle has approached to any one of the check point sets based on the coordinate of a current vehicle position and the coordinate of the check point set, detecting a next check point based on a relation between each of check points contained in that check point set and a check point detected in the last time and performing associated processes such as a voice guidance and automatic sampling of operation record for that check point.
