摘要： PROBLEM TO BE SOLVED: To solve the problem that, conventionally, in rolling control for keeping a working machine such as a tractor, in parallel on a hillside, since an inclination standard value is obtained by the moving average of sensor detected values in a prescribed time, when an abnormal value appears by local unevenness on the surface of soil or a sensor noise, the abnormal value greatly affects an average value until the prescribed time is passed, and as a result, the rolling posture of the working machine is not accurately controlled.
SOLUTION: A tractor 1 is equipped with a slope sensor and the detected values of the slope sensor are obtained for each prescribed time to calculate a first average value. The first average value and the newly obtained latest detected values of the slope sensor are averaged to calculate a second average value and the second average value is set as the inclination standard value α. The second average value is calculated from the moving average of the first average value and the latest detected values of the sensor.

摘要： PROBLEM TO BE SOLVED: To provide a steering control device of a working vehicle capable of increasing safety and operability since the sharp turning of front wheels 13 is eliminated when a vehicle is not turned in working, for example, when the vehicle adjusts its course to change a lane in traveling or turns at a square crossing and capable of increasing durability since the front wheels are not always turned excessively and the wear of tires is reduced.
SOLUTION: An intermediate case 4 is rotatingly supported on an axle casing 1 at both ends, and an axle case 3 steered through a power steering 2 is rotatingly supported on the outside of the intermediate case 4. An actuator 7 is installed in the intermediate case 4. When the vehicle travels on a road, the front wheels 13 are steered by the power steering 2 only, and when the vehicle is at work, the front wheels 13 are steered together with the actuator 7. In addition, when the vehicle is at work, the intermediate case 4 is driven to a swing inner side simultaneously or after the high-speed driving of the front wheels 13 and simultaneously or after the output of a rear wheel brake on the swing inner side.
