Abstract
A system includes a series of converters provided along a boundary of an agricultural cultivated area. A converter is configured to emit a second signal in response to an incoming first signal. The system also includes an autonomously driving agricultural machine including a transmitting device configured to emit the first signal in an environment of the agricultural machine, a receiving device configured to receive the second signal emitted in response to the first signal, and a processing device configured to determine a position of the agricultural machine with respect to the boundary based on the received second signal. An arrangement and/or a conversion characteristic of converters is designed differently at a first section of the boundary than at a second section of the boundary.
Claims11
A system, comprising:
- a series of converters provided along a boundary of an agricultural cultivated area, wherein a converter is configured to emit a second signal in response to an incoming first signal;
- an autonomously driving agricultural machine including a transmitting device configured to emit the first signal in an environment of the agricultural machine, a receiving device configured to receive the second signal emitted in response to the first signal, and a processing device configured to determine a position of the agricultural machine with respect to the boundary based on the received second signal,
- wherein an arrangement and/or a conversion characteristic of converters is designed differently at a first section of the boundary than at a second section of the boundary.
A method for determining a position of an agricultural machine with respect to a boundary of an agricultural cultivated area wherein a series of converters are provided along the boundary, wherein a converter is configured to emit a second signal in response to an incoming first signal;
- and the method comprising:
- emitting at least one first signal in an environment of the agricultural machine;
- receiving at least one second signal emitted in response to the at least one first signal;
- and
- determining the position of the agricultural machine based on the at least one received second signal.
A control device for an agricultural machine, which is configured to autonomous drive on an agricultural cultivated area, the control device comprising:
- a transmitting device configured to emit at least one first signal in an environment of the agricultural machine;
- a receiving device configured to receive a plurality of second signals that have been emitted in response to the at least one first signal;
- a memory device configured to store positions of converters of the first signal in the second signal along the boundary of the cultivated area;
- and
- a processing device configured to determine a position of the agricultural machine with respect to the boundary based on one or more received second signals.
