`Bevice for an infotainment system
`
`The invention reiates to a device, a system comprising a device and an
`
`infotainment system, and a method for operating a device and an
`
`U;
`
`infotainment system.

`
`An infotainment system can be arranged in a motor vehicie and can be
`
`designed to provide information about a current trip and/or operating
`
`parameters of the motor vehicie to occupants, generaiiy at toast to the driver.
`
`Furthermore, audio and video data can be presented to the occupants by
`
`means of the infotainment system via output apparatuses, eg. via a monitor
`
`and via ioudspeaiters. it is possihie that said audio and video data hear no
`
`reiation to the trip orto the motor vehicie. The infotainment system can obtain
`
`information andlor data from the internet.
`
`in tight of this, the propiem addressed was that of using appiications from the
`
`internet by means of an infotainment system without having to have an
`
`operating system intended for this purpose.
`
`This prooiem is soived by means of a device, a system, and a method having
`
`the features of the independent ciaims. Embodiments of the device, of the
`
`system, and of the method are ciear from the dependent ciaims and the
`
`descnphon.
`
`The device according to the invention is intended for an infotainment system
`
`that has a computing unit on which a first operating system is instaiied and
`
`can he executed, whereas the device has a computing unit on which a
`
`second operating system is instaiied and can be executed. Radiousupported
`
`communication with the internet can be carried out by means of the second
`
`30
`
`operating system. The device has at ieast one generic interface to the

`
`infotainment system, which iikevvise has at ieast one generic interface. By
`
`means of the infotainment system, aooiications intended and/or designed for
`
`the second operating system can be provided and/or used via the device.
`
`The first operating system is different from the second operating system.
`
`in one design, the radio—supported communication of the device with the
`
`internet is carried out indirectiy via at ieast one generic radio interface of the
`
`infotainment system, which generic radio interface is Lisuaiiy designed as an
`
`antenna. it is oossihie that the infotainment system provides data to the
`
`device from the at ieast one generic interface of the infotainment system via
`
`the at ieast one generic interface of the device. The communication of the
`
`device with the internet is enacted by means of the at ieast one generic radio
`
`interface of the infotainment system, said at ieast one generic radio interface
`
`being designed as an antenna in one design. in generai, the infotainment
`
`system can communicate with the at ieast one generic interface of the device
`
`via a first generic interface and with the internet via the generic radio
`
`interface. By means of the communication chain provided by the generic
`
`interfaces and the generic radio interface, the device has access to the
`
`internet.
`
`in one design, the infotainment system is arranged in a motor vehicie. The at
`
`ieast one generic radio interface of the infotainment system, which is
`
`designed as antenna, can at the same time aiso be designed as a generic
`
`radio interface of the motor vehicie, by means of which the radio—supported
`
`communication with the internet can be carried out.
`
`it is therefore oossihie, inter aiia, forthe infotainment system, by means of
`
`the device, to use a oiatform for the use of aooiications from the internet that
`
`are designed forthe second operating system out not forthe first operating
`
`30
`
`system.

`
`The device is designed to exchange data with the infotainment system via
`
`the at ieast one generic interface.
`
`in one design, the device is designed as a portabie, mobiie apparatus that
`

`operating system is instaiied and can be executed, and at ieast one generic
`
`interface. The device has a computing unit, on which a second operating
`
`system is instaiied and can he executed. By means of the second operating
`
`system, radio-supported communication with the internet can be carried out.
`
`The device iiitevvise has at ieast one generic interface. The generic interfaces
`
`of the device and of the infotainment system are ccmpatibie with each other,

`
`component of the infotainment system. The device and the infotainment
`
`system can be operated ohiy by means of the at ieast one input apparatus of
`
`the infotainment system. The person can use said at ieast one input
`
`apparatus as a human~machine interface for inputting commands and/or for
`
`operating the device. Accordingiy, a separate input apparatus is not required
`
`for the device, because the device can be operated by means of the input
`
`apparatus of the infotainment system.
`
`Furthermore, it is provided that the has at ieast one output apparatus, for

`38 of the device 6 are connected to each ether here by means of a seriai bus
`
`system 50, eg. USE, via the two generic interfaces 36, 38! data f9a, 34a for
`
`a dispiay and data f9c, 34c for an audio output are provided to the device 6
`
`by the infotainment system 4. in addition, data 19h, 34b for operating an
`
`input apparatus 10a, 16b, data 19d, 34d for controiiing the motor vehicie,
`
`data tee, 34o from the internet, and data 19f, 34f for authentication are
`
`exchanged between the infotainment system 4 and the device 6.
`
`in figure 3, further detaiis of the device 6 are schematicaiiy iiiustrated. The
`
`computing unit 21 comprises a processor core 52 (muithcore), a iviEivi 54, by
`
`means of which the computing unit 21 is connected to a first memory 56, and
`
`an MMC 58, by means of which the computing unit 21 is connected to a
`
`second memory 80. The computing unit 21 can be connected to an energy
`
`source 64 of the infotainment system 4 by means of an energy connection
`
`52. By means of a communication connection 66, the computing unit 21 can
`
`be connected to an antenna 88 as a generic radio interface of the
`
`infotainment system 4, by means of which antenna the computing unit 21 can
`
`exchange data with the internet 14. Furthermore, the computing unit 21
`
`comprises a first generic interface 38a (HDME), a second generic interface
`
`38p (SD), and a third generic interface 38c (USB). in addition; the device 8
`
`comprises a hardware authentication means 70 for authenticating hardware.
