Description
【０００２】
【従来の技術、及び課題】
従来、作業車両には、特開平８−１５６８１２号公報に示されているトラクタのように、耕耘作業での枕時旋回にステアリング操作を軽減するため、ステアリングハンドルの操作量に対して前輪の切れ角度を変更可能な操向装置を設けたものが知られている。[0002]
[0003] Prior art and problems
Conventionally, work vehicles, such as the tractor shown in Japanese Patent Laid-Open Publication No. 8-156812, are known to be equipped with a steering device that can change the turning angle of the front wheels in response to the amount of steering of the steering handle in order to reduce steering operation when turning while plowing.

また、図６に示されたフローチャートは、この発明の別形態でありＳＴＥＰ４にて、オペレータの操向速度を検出する条件を加えている。即ち、前記トラクタ１０の前輪切角センサ９より単位時間当たりの切れ角から操向速度を検出して、この速度が小回り旋回と想定される操作速度以上であれば、他の条件の判定と合わせてステアリングハンドル３の操作量に対し前輪４，４の操向量を増大する構成としている。[0018]
6 is another embodiment of the present invention, and adds a condition for detecting the steering speed of the operator in STEP 4. That is, the steering speed is detected from the steering angle per unit time by the front wheel turning angle sensor 9 of the tractor 10, and if this speed is equal to or greater than the operation speed assumed for a tight turn, the amount of steering of the front wheels 4, 4 is increased relative to the amount of operation of the steering wheel 3 in conjunction with the determination of other conditions.
