The old data stored in the memory is replaced with the first learned meet position data when the difference between the old data and the first learned meet position data is greater than a prescribed value. The old data is corrected by the use of the old data and the learned data when the difference is not greater than the prescribed value even if the learned data is the first learned meet position data.
