专利汇可以提供Automatic steering control device for farm-working machine专利检索,专利查询,专利分析的服务。并且PURPOSE: To attain good steering result independently of the field condition and the skill of the operator by preparing a steering rule from the steering angle and the deviation from a virtual straight line at the time of the trial steering of a farm- working machine.
CONSTITUTION: At first, a farm-working machine is operated by an operator by steering a steering wheel to form a standard crop row e.g., by transplanting seedlings. The farm work is repeated along a side of the standard crop row while picking up the crop row with an image-pickup means 34 to extract (35) the characteristic features. The crop row relative to the standard in the farm working operation is assumed as a virtual straight line. The virtual line is calculated (36), the deviation of the virtual line from the standard of the image-pickup means, etc., is calculated (36), the real steering angle of the farm-working machine is detected at the same hour and the relationship between the steering extent and the deviation angle and lateral deviation relative to the standard of the virtual line is calculated. Once a steering rule is made from the relationship by a rule-making means 39, the machine can be automatically steered in accordance with the steering rule in such a manner as to keep the deviation of the virtual line within a prescribed allowable range.
