To provide a garage guiding device for computing a vehicle track for minimizing steering operation and shift operation even in the case of a parking place or a garage having restrictions on the road width and guiding a vehicle to the track.

A garage guiding device for a vehicle has an image processing device 12 for processing surrounding environmental images obtained by lateral side cameras 1, 11 and a rear camera 2, to compute the position and attitude of the vehicle and roads width to a white line of a garage frame, lateral wheel speed sensors 8, 9 for detecting the moving quantity of the vehicle, and a steering angle sensor 5 for detecting the steering angle of the vehicle; and a track for entering a garage is computed from the position and attitude of the vehicle and the road with to the white line of the garage frame computed by the image processing device 12. The track for entering the garage is computed from the relation between the garage width and road width.
