PURPOSE: An auto-cruise system is provided to utilize an auto-cruise system in a low-speed vehicle by properly accelerating and decelerating a vehicle. CONSTITUTION: A planetary gear device(5) comprising a ring gear(6), a planetary gear(7) and a sun gear(8) is engaged with an auxiliary gear(4). Many planetary gears are formed on the inner face of the ring gear. If a motor(9) is driven, the sun gear circumscribing the planetary gears rotates by the rotational power of the motor. The planetary gears are fixed on one face of a disk(10), and a rotating guide(11) is fixed on the other face of the disk. When a driver selects an auto-cruise mode, the rpm of the motor is determined depending on an inputted speed. The sun gear is rotated by the determined motor rpm. If the ring gear is rotated, the planetary gears rotate and revolve around the sun gear. Acceleration and deceleration are performed by a contact terminal(11a) contacting a brake terminal(12a) or an accelerator terminal(12b).
