1. An assist control device of a vehicle, comprising:
- a positioning unit that measures a position of the vehicle;
an assist control execution unit that executes assist control according to the position of the vehicle measured by the positioning unit;
an accuracy error calculation unit that calculates an accuracy error that is caused when the position of the vehicle is measured by the positioning unit, the accuracy error being accumulated as the vehicle moves; and
a control level change unit that changes a control level of the assist control executed by the assist control execution unit so as to correspond to the accuracy error calculated by the accuracy error calculation unit.

Abstract
An accuracy error for measuring the position of an own vehicle is calculated based on the information of an execution history of map matching and the information of an update history of a map database. In addition, a predetermined map is referred to based on the calculated accuracy error, and an accuracy error level for performing positioning is specified from among plural stepwise levels. Then, the control level of assist control executed according to the position of the own vehicle is changed so as to correspond to the specified accuracy error level.
