VEHICLE POSITIONING INFORMATION UPDATING SYSTEM

摘要

Based on positioning accuracy of an own vehicle required for appropriately carrying out assistance control carried out according to a position of the own vehicle, an execution condition for map matching correcting the position of the own vehicle is set. Specifically, setting is made in such a manner that, as the positioning accuracy is higher and an error thereof is smaller, an execution frequency of map matching becomes higher. Then, map matching is carried out according to the thus-set execution condition.
