摘要： An automatic steering system for a working vehicle, for automatic maneuvering of the working vehicle running on a working ground surface along a desired running path, in which the influences of various ground surface environments and of any aging degradation and/or individual variation of the working vehicle may be minimized, and the automatic steering operation may be conducted with improved stability. The automatic steering system includes a measurement section for acquiring measurements including those of the position, velocity, heading direction, and attitude of the vehicle and a data processing section. The data processing section includes a vehicle related parameter estimator for determining a value of a vehicle related parameter and a ground surface related parameter estimator for determining a value of a ground surface related parameter.

摘要： A position output device for outputting position data indicating a current position of an object, is based on position data of a determined current position of the object as determined by a satellite navigation system. When a position jump has occurred in the position data from the satellite navigation system, an appropriate current position is outputted. An estimated current position is generated based on the output position outputted at the latest update time. It is determined whether or not a position jump has occurred, based on the distance between the estimated position and the satellite navigation system-based determined position, which is being updated by the satellite navigation system. When it is determined that a position jump has occurred, a position adjustment vector is generated by calculation, which is then used to generate an adjusted position.
