摘要： A control method of a vehicle (1) according to the present disclosure is a control method for controlling the vehicle (1) that has tires (6) mounted thereon and drives autonomously on a course (200) that includes a banked section. The control method includes a setting step of setting a weighting for a plurality of sensors (12) configured to detect information about the vehicle (1) or the course (200), and a detection step of performing detection of a position of the vehicle (1) and/or an obstacle around the vehicle (1) using the weighting for the plurality of sensors (12) and a detection result of the sensors (12). In the setting step, the weighting is changed between the banked section (230) and sections other than the banked section (230).

摘要： A method of harvesting a seed from a rooted plant utilizing a seed harvester. The method includes dislodging the seed from the rooted plant via a seed dislodging system on the seed harvester by contacting the rooted plant with at least one of a plurality of dislodging members of the seed dislodging system. The method also includes collecting the seed via a seed collection system on the seed harvester. The method further includes transporting the seed via a seed transport system on the seed harvester from the seed collection system to a seed isolation system on the seed harvester. The method also includes isolating the seed from a waste material via the seed isolation system. A seed harvester is also included.
