PROBLEM TO BE SOLVED: To rationalize a dead zone during tilt control with an angular velocity sensor and to carry out the tilt control with high accuracy utilizing performances of the angular velocity sensor. SOLUTION: The right and left tilts of an implement 3 are automatically controlled on the basis of values detected with a tilt sensor 7 and the angular velocity sensor 8. In the process, values detected with the angular velocity sensor 8 are integrated to provide tilt data when the values detected with the angular velocity sensor 8 are in a variable state. When the values detected with the angular velocity sensor 8 are in a stable state, values detected with the tilt sensor 7 are used as the tilt data to judge the right and left tilt angles of the implement 3. Furthermore, when the tilt data on the basis of the angular velocity sensor 8 are used, a dead zone narrower than the case in which the tilt data of the tilt sensor 7 are used is applied to carry out the tilt control of the implement 3.
