Abstract

A display device for a bicycle, e.g., a Pedelec, and/or a bicycle element, and a method of operating a bicycle with a display device are disclosed. The display device includes a carrier for mounting on a handlebar of the bicycle or for mounting on a bicycle helmet. On the carrier, a plurality of controllable luminous elements are arranged.

First claim

The invention claimed is:

1. A display device for at least one of a bicycle and a bicycle helmet, comprising:
a carrier for mounting on a handlebar,
a plurality of controllable luminous elements arranged on the carrier, and
wherein the carrier includes an annular or hollow-cylindrical geometry and is structured in two parts for mounting on the handlebar and includes two ring segment-shaped carrier elements, the two ring segment-shaped carrier elements connected to one another in an articulated manner via a hinge and adjustable between a closed position where the two carrier elements enclose an annular opening, and an open position where the two carrier elements are mountable on the handlebar or demountable from the handlebar.

2. The display device according to claim 1 , wherein the carrier further includes a fixing device arranged on two circumferential ends of the two carrier elements facing away from the hinge, and wherein the fixing device fixes the two carrier elements to one another in the closed position.

3. The display device according to claim 1 , wherein at least one of the plurality of luminous elements is arranged on a front side of the carrier.

4. The display device according to claim 1 , wherein one of:
at least one of the plurality of luminous elements is arranged on an outer circumferential side of the carrier;
all of the plurality of luminous elements are arranged on a front side of the carrier; or
a first part of the plurality of luminous elements is arranged on the carrier on a circumferential side of the carrier and a second part of the plurality of luminous elements is arranged on a front side of the carrier.

5. The display device according to claim 1 , wherein on the carrier an electrical connection is provided, wherein the electrical connection electrically connects the plurality of luminous elements by wire to a control/regulating device.

6. The display device according to claim 1 , wherein the plurality of luminous elements are configured to be separately controllable.

7. The display device according to claim 1 , wherein at least one of:
the plurality of luminous elements are covered via a protective cover that is transmissive for the light emitted by the plurality of luminous elements;
at least one of the plurality of luminous elements is configured to emit light with one of at least two different colours; and
at least one of the plurality of luminous elements is configured to emit light with different brightness.

8. A bicycle, comprising:
a rear wheel and a front wheel that is steerable by a user;
a seat, on which the user can sit;
a handlebar for controlling the front wheel;
at least one radar sensor arranged in a rear region configured to monitor a rear surrounding region at a back at least in regions for the presence of at least one further road user;
a control/regulating device connected to the at least one radar sensor in a data-transmitting manner for receiving sensor data generated by the at least one radar sensor;
at least one display device arranged on the handlebar, the at least one display device including a carrier and a plurality of controllable luminous elements arranged on the carrier;
wherein the at least one display device is connected wirelessly or by wire to the control/regulating device, so that the control/regulating device can control the plurality of luminous elements as a function of the sensor data received; and
wherein the carrier includes an annular or hollow-cylindrical geometry and is structured in two parts for mounting on the handlebar and includes two ring segment-shaped carrier elements, the two ring segment-shaped carrier elements connected to one another in an articulated manner via a hinge and adjustable between a closed position where the two carrier elements enclose an annular opening, and an open position where the two carrier elements are mountable on the handlebar or demountable from the handlebar.

9. The bicycle according to claim 8 , wherein the at least one display device is arranged on the handlebar so that the user sitting on the seat can see the plurality of luminous elements.

10. The bicycle according to claim 8 , wherein the control/regulating device controls at least one of the plurality of luminous elements such that the at least one luminous element, relating to the emission of light, changes its previous state when, via the at least one radar sensor, the presence of at least one road user has been detected and sensor data corresponding to the said detection were transmitted to the control/regulating device by the at least one radar sensor.

11. The bicycle according to claim 8 , wherein the at least one radar sensor is structured and arranged such that it can be distinguished by the at least one radar sensor whether a detected road user is situated in a laterally left region behind the bicycle or in a laterally right region behind the bicycle or in a middle region between the laterally left region and the laterally right region.

12. The bicycle according to claim 8 , wherein the handlebar includes a left handlebar half and a right handlebar half, wherein on at least one of the left handlebar half and the right handlebar half the display device is arranged in each case, and wherein the plurality of luminous elements are controllable by the control/regulating device.

13. The bicycle according to claim 8 , wherein the handlebar includes a left handle and a right handle, wherein in a left region or a right region of at least one of the left handle and the right handle the display device is arranged in each case, and wherein the plurality of luminous elements are controllable by the control/regulating device.

14. The bicycle according to claim 8 , wherein the carrier further includes a fixing device arranged on two circumferential ends of the two carrier elements facing away from the hinge, and wherein the fixing device fixes the two carrier elements to one another in the closed position.

15. A method for operating a bicycle, comprising:
monitoring a surrounding rear region of the bicycle via at least one radar sensor;
transmitting sensor data from the at least one radar sensor to a control/regulating device;
controlling via the control/regulating device at least one of a plurality of luminous elements of at least one display device such that regarding to the emission of light the at least one luminous element changes its previous state when via the at least one radar sensor a change of status regarding a road user behind the bicycle has been detected and the sensor data corresponding to the change of status are transmitted to the control/regulating device by the at least one radar sensor;
the control/regulating device for switching-on/switching-off/switching-over of the at least one luminous element controls the at least one display device arranged on a left handle of a handlebar when via the at least one radar sensor it has been detected that the detected road user is situated in a laterally left region behind the bicycle;
the control/regulating device for the switching-on/switching-off/switching-over of the at least one luminous element controls the at least one display device arranged on a right handle when via the at least one radar sensor it has been detected that the detected road user is situated in a laterally right region behind the bicycle; and
the control/regulating device for the switching-on/switching-off/switching-over of the at least one luminous element controls both the at least one display device arranged on the left handle and the at least one display device arranged on the right handle when via the at least
