Agricultural tractor having a system for identifying downstream road users

1. An agricultural tractor having a system for identifying downstream road users, comprising:

a control unit in communication with a user interface;

a sensor having a detection range which runs in a vicinity of the ground and which is in a direction of an attachment connected to the agricultural tractor, the sensor configured to identify a vehicle located in the detection range or which enters therein, the sensor configured to generate a corresponding message signal which is supplied to the control unit, and the control unit activating the user interface based on the message signal for the output of a driver message;

wherein a free region which is visible from the agricultural tractor by the sensor is formed between a road surface and a lower contour of the attachment facing the road surface;

wherein the sensor is coupled to a load-bearing structure of the agricultural tractor, and

wherein the sensor is located below a rear axle of the agricultural tractor.

2. The agricultural tractor of claim 1 , wherein the sensor comprises a radar sensor.

3. The agricultural tractor of claim 1 , wherein the sensor comprises an image-forming sensor.

4. The agricultural tractor of claim 1 , wherein the sensor comprises a camera.

5. The agricultural tractor of claim 1 , wherein the attachment comprises a transport trailer or cultivation device.

6. The agricultural tractor of claim 1 , wherein the sensor is coupled to a lower face of the load-bearing structure.

7. The agricultural tractor of claim 1 , further comprising a mount for coupling the sensor to the load-bearing structure.

8. The agricultural tractor of claim 1 , further comprising a shield for at least partially surrounding the sensor.

9. The agricultural tractor of claim 1 , further comprising a cleaning device including a wiper or nozzle for removing any dirt or debris from the sensor.

10. An agricultural tractor for operating along a ground surface, comprising:

a chassis supported by one or more wheels;

an attachment coupled to the chassis;

a control unit for controlling the tractor;

a user interface in communication with the control unit, the user interface configured to output operator messages from the control unit;

a sensor coupled to the chassis and disposed in communication with the control unit, the sensor configured to sense a detection range defined along the ground surface and in a direction towards the attachment;

wherein during use, the sensor is configured to detect an object entering the detection range and generate a signal to the control unit indicative of the object;

wherein upon receiving the signal from the sensor, the control unit operably activates the user interface to output a message based on the signal;

wherein the sensor operably senses a free region within the detection range, the free region being defined between the ground surface and a lower surface of the attachment;

wherein the sensor is coupled to a load-bearing structure of the agricultural tractor; and

wherein the sensor is located below a rear axle of the agricultural tractor.

11. The agricultural tractor of claim 10 , wherein the sensor comprises a radar sensor or an image-forming sensor.

12. The agricultural tractor of claim 10 , wherein the sensor comprises a camera.

13. The agricultural tractor of claim 10 , wherein the attachment comprises a transport trailer or cultivation device.

14. The agricultural tractor of claim 10 , wherein the sensor is coupled to a lower face of the load-bearing structure.

15. The agricultural tractor of claim 10 , further comprising a mount for coupling the sensor to the load-bearing structure.

16. An agricultural tractor for operating along a ground surface, comprising:

a chassis including a mount;

a plurality of wheels supporting the chassis above the ground surface, where at least two of the plurality of wheels defines a rear axle of the tractor;

an attachment coupled to the chassis;

a control unit for controlling the tractor;

a user interface in communication with the control unit, the user interface configured to output operator messages from the control unit;

a sensor coupled to the chassis via the mount and being located below the rear axle, the sensor configured to sense a detection range defined along the ground surface and in a direction towards the attachment;

a shield surrounding the sensor; and

a cleaning device for operably cleaning the sensor from any dirt or debris;

wherein, during use, the sensor is configured to detect an object entering the detection range and generate a signal to the control unit indicative of the object;

wherein, upon receiving the signal from the sensor, the control unit operably activates the user interface to output a message based on the signal;

further wherein, the sensor operably senses a free region within the detection range, the free region being defined between the ground surface and a lower surface of the attachment.
