Abstract: An autonomous vehicle navigation system includes a controller configured or programmed to receive environment or location information a work vehicle detected by a sensor, receive user input data, and cause the work vehicle to traverse and exit a first row in the first plot, traverse a margin area located between the first plot and an adjacent field, and perform a turning maneuver process before entering a second row in the first plot. The controller determines, before the work vehicle starts driving, whether or not to turn on a turning area wider function based on a first condition group being satisfied based on the user input data. During the turning maneuver process, the controller judges whether or not the work vehicle is allowed to enter a third row of the adjacent field based on a second condition group being satisfied based on the information detected by the sensor.

Abstract: An autonomous vehicle navigation system includes a controller configured or programmed to receive information of a work vehicle, receive data input from a user, and cause the work vehicle to traverse a first plot, exit the first plot; traverse a margin area located between the first plot and an adjacent area or a second plot, and perform a turning maneuver process before entering a second row in the first plot. When the work vehicle performs the turning maneuver, the controller allows at least a portion of the work vehicle to reverse into the adjacent area or a third row included in the second plot based on the controller judging whether or not at least one or more conditions is satisfied, the one or more conditions being based on data detected from at least one sensor and/or the input data from the user.

Abstract: A vehicle speed control system that controls a vehicle speed of an agricultural vehicle that performs work using a work device while traveling using a traveling device, the agricultural vehicle performs work travel a plurality of times with non-work travel interposed therebetween, the vehicle speed control system including: a control unit configured to perform work travel control in which a vehicle speed is set according to a load on a motive power source that drives the traveling device and the work device; and a storage unit in which a vehicle speed that is set during the work travel is stored as an optimum vehicle speed, the control unit performs initial work travel control in which a vehicle speed at a time when the work travel is started after the non-work travel is set using the optimum vehicle speed that is stored during the work travel performed before the non-work travel.
