Description

DESCRIPTION OF THE FIGURES

[0032] Further details and advantages of the present invention will become apparent from the following description of the exemplary embodiment in conjunction with the drawing, in which

[0033] FIG. 1 shows a schematic structure of a system comprising a breakdown assistance device and an on-board computer in a vehicle.

[0034] FIG. 1 shows a schematic structure of a system for sealing and inflating vehicle tires, comprising a breakdown assistance device 1 and a vehicle 2, wherein the vehicle 2 has a vehicle interface 3, an on-board computer 4 and at least one vehicle tire 5, wherein the vehicle interface 3 is able to communicate with the on-board computer 4. The communication paths are marked by arrows, wherein the direction of the arrow describes the communication direction. Communication is understood to mean both a power supply and data transmission.

[0035] The breakdown assistance device 1 furthermore has an interface 6 according to the invention, which is designed for supplying power and transmitting data, a data processing device 7, a compressor 8 and an optional sealant distributor device 9. It is essential that the sealant distributor device 9 is able to be connected to the breakdown assistance device 1 via a feed opening. The sealant distributor device 9 does not have to be part of the breakdown assistance device 1. The interface 6 is able to communicate with the data processing device 7, which is able to communicate with the compressor 8 and/or with the optional sealant distributor device 9. The breakdown assistance device 1 may be connected to the vehicle tire via a hose on the valve of the vehicle tire 5.

[0036] The interface 5 may be connected to the on-board computer 4 by a cable, by a user via the vehicle interface 3, as a result of which the breakdown assistance device 1 is supplied with power. The user is able to operate and control the breakdown assistance device 1 via the on-board computer 4 in the vehicle 2. For this purpose, the breakdown assistance device 1 is able to be switched on and off at the on-board computer 4. It is furthermore possible for the user to control the infeed of air via the compressor 8 and the infeed of the sealant via the sealant distributor device 9 on the on-board computer 4. The user is thus able to fill the vehicle tire 5 with air or with sealant from inside the vehicle. For this purpose, for example, the air pressure or the fill level of the sealant may be read on the on-board computer 4. When the filling process is complete, the user is able to disconnect the breakdown assistance device 1 from the vehicle tire 5. The optional sealant distributor device 9 may be removed from the feed opening of the breakdown assistance device 1 and replaced with a new one.
