PROBLEM TO BE SOLVED: To provide a travel controller which improves a possibility that when a vehicle is made to autonomously travel to a goal position, the vehicle reaches the goal position. SOLUTION: The travel controller 100 compares a linear distance d<SB POS="POST">a</SB>set when a last correction is made during a travel of the vehicle 1 with a linear distance d<SB POS="POST">n</SB>from the current vehicle position of the vehicle 1 to a parking position O as a goal, and tries to re-recognize the parking position O as the goal when the linear distance d<SB POS="POST">n</SB>is shorter than the linear distance d<SB POS="POST">a</SB>. Consequently, each time the vehicle 1 approaches the goal position O, the parking position O as the goal can be re-recognized, so an error included in a re-recognized parking position O' can be gradually decreased (stepwise). Consequently, specific precision of the parking position O as the goal can be gradually improved (stepwise), so the possibility that the vehicle 1 reaches the parking position O as the goal can be improved.
