Agricultural machine operable in a combined or in a separated configuration
An agricultural machine having an auxiliary vehicle with a driver's workplace, an agricultural vehicle with a loading ramp for transporting the auxiliary vehicle and a control unit. The agricultural machine is operable in a combined configuration in which the auxiliary vehicle is placed on the loading ramp or in a separated configuration in which the auxiliary vehicle is removable from the loading ramp. The driver's workplace has a human machine interface for controlling a manual driving function of the agricultural vehicle and a manual driving function of the auxiliary vehicle. The control unit is configured to disable the manual driving function of the auxiliary vehicle if the combined configuration of the agricultural machine is present and to enable the manual driving function of the auxiliary vehicle if the separated configuration of the agricultural machine is present.
1 . An agricultural machine comprising:
an auxiliary vehicle comprising a driver's workplace;
an agricultural vehicle comprising a loading ramp for transporting the auxiliary vehicle and a protective structure being moveable between a released position and a secured position for protecting the auxiliar vehicle when placed on the loading ramp; and
a control unit;
wherein the agricultural machine is operable in a combined configuration or in a separated configuration;
wherein the driver's workplace comprises a human machine interface for controlling a manual driving function of the agricultural vehicle and a manual driving function of the auxiliary vehicle; and
wherein the control unit is configured to disable the manual driving function of the auxiliary vehicle if the combined configuration of the agricultural machine is present and to enable the manual driving function of the auxiliary vehicle if the separated configuration of the agricultural machine is present.
2 . The agricultural machine of claim 1 , wherein the control unit is configured to enable an autonomous driving function of the agricultural vehicle if the separated configuration of the agricultural machine is present.
3 . The agricultural machine of claim 1 , wherein the agricultural vehicle comprises a lifting device for moving the loading ramp between a loading position and a transport position.
4 . The agricultural machine of claim 3 , wherein the lifting device is configured to move the loading ramp in a direction deviating from an orientation of a longitudinal axis of the agricultural vehicle.
5 . The agricultural machine of claim 3 , wherein the control unit is configured to enable the manual driving function of the agricultural vehicle and to disable the manual driving function of the auxiliary vehicle if the loading ramp is in the transport position.
6 . The agricultural machine of claim 3 , wherein the control unit is configured to enable the manual driving function of the auxiliary vehicle if the loading ramp is in the loading position.
7 . The agricultural machine of claim 3 , wherein the separated configuration of the agricultural machine is present when the loading ramp reaches the loading position with the auxiliary vehicle placed on the loading ramp.
8 . The agricultural machine of claim 3 , wherein the combined configuration of the agricultural machine is present when the auxiliary vehicle is placed on the loading ramp to move the loading ramp carrying the auxiliary vehicle from the loading position to the transport position.
9 . The agricultural machine of claim 1 , wherein the protective structure is arranged at the loading ramp.
10 . The agricultural machine of claim 1 , wherein the control unit is configured to disable the manual driving function of the agricultural vehicle if the protective structure is in the released position and if the combined configuration of the agricultural machine is present.
11 . The agricultural machine of claim 1 ,
wherein the agricultural vehicle comprises a securing element for fastening the auxiliary vehicle to the loading ramp; and
wherein the control unit is configured to disable the manual driving function of the agricultural vehicle unless the auxiliary vehicle is fastened if the combined configuration of the agricultural machine is present.
12 . The agricultural machine of claim 1 , wherein a longitudinal axis of the auxiliary vehicle is oriented along a cross axis of the agricultural vehicle if the combined configuration of the agricultural machine is present.
13 . The agricultural machine of claim 1 ,
the driver's workplace comprising a seat rotatable around a rotation axis; and
wherein the control unit is configured to disable the manual driving function of the agricultural vehicle unless a seating position of the seat is oriented along a longitudinal axis of the agricultural vehicle if the combined configuration of the agricultural machine is present.
14 . The agricultural machine of claim 1 , the agricultural vehicle comprising a front part, a rear part and an articulated steering connecting the front part with the rear part and having a vertical axis as steering axis.
15 . The agricultural machine of claim 14 , wherein the loading ramp is arranged at the rear part.
16 . The agricultural machine of claim 1 ,
wherein the agricultural vehicle comprises a lifting device for moving the loading ramp between a loading position and a transport position,
wherein the agricultural vehicle comprises a securing element for fastening the auxiliary vehicle to the loading ramp,
wherein the control unit is configured to disable the manual driving function of the agricultural vehicle unless the auxiliary vehicle is fastened if the combined configuration of the agricultural machine is present, and
wherein the human machine interface is configured to control the lifting device, the protective structure and/or the securing element.
