<p>PROBLEM TO BE SOLVED: To prevent the deviation of a vehicle from a moving track while preventing the generation of slip of wheels due to the excessive driving torque during the automatic steering control. SOLUTION: In the case where a forward traveling shift range except for (P). (N), (R) is detected by a shift range detecting means S4 during the automatic steering control for garaging, a speed change control device 24 forcibly fixes the number of speeds of an automatic transmission T at a two-stage of speed by a command from a control part 22 of a steering control device 21. Even in the case where a driver excessively operates an acceleration pedal 10 during the automatic steering control for driving a steering actuate 7 on the basis of the moving track stored in a memory unit 23, since the number of speeds is fixed to the two-stage of speed, excessive increase of the wheel driving torque is restricted so as to prevent the generation of slip, and deviation of a vehicle V from the moving track is prevented.</p> |
