AGRICULTURAL WORK VEHICLE

摘要

PROBLEM TO BE SOLVED: To solve the problems of an agricultural work vehicle comprising poor characteristics in the case of moving a tractor from a stop position using a relatively low-cost inclination sensor and the failure in the improvement of the control accuracy in the case of using the relatively low-cost inclination sensor owing to the generation of response delay caused by the poor characteristics. SOLUTION: The tractor 1 is provided with an inclination sensor 16, an angular velocity sensor 19 to detect the variation speed of the lateral inclination angle of the tractor 1, and a controlling device 60 to control the relative angle between the tractor 1 and a rotary tiller 14. The controlling device 60 of the tractor 1 controls the relative angle based on the detection value of the inclination sensor 16 when the detection value of the angular velocity sensor 19 is within a definite preset range and controls the relative angle by a negative feedback operation to decrease the angular velocity detected by the angular velocity sensor 19 when the detection value of the angular velocity sensor 19 is out of the preset range.
