Motor vehicle communication system, arrangement with processor, computer program product and computer-readable storage medium

Technical field

The invention relates to a motor vehicle navigation system with a mobile phone, an arrangement with a processor, a computer program product and a computer-readable storage medium.

State of the art

In addition to a conventional car radio, modern motor vehicles are also increasingly being equipped with a navigation device. In addition, an increasing number of vehicle owners have a mobile phone, which according to the existing legal regulations when operating in a motor vehicle can only be operated via a hands-free system. For future driver information systems with additional Internet access, as well as for so-called off-board

Navigation systems require a connected mobile phone. Together, this represents a series of electronic devices, each of which has a housing that has to be accommodated on the dashboard of the vehicle, as well as associated devices such as antenna, loudspeaker, microphone, etc. Apart from the sometimes double effort for individual elements (for example a mobile phone) ) mostly comes across Accommodation of the devices within easy reach of the driver on borders. If the space for a car radio is already provided for older vehicles, the accommodation of only one additional device - navigation device or hands-free device - is a problem. Even in the case of new vehicles that have a navigation system or are prepared to accommodate one, it is again not easily possible to attach a hands-free device or vice versa. Solutions are then sought, for example to mount a hands-free device on top of the dashboard, in the door area or in a similar manner. Not only that the quality of view of such accommodation is not particularly high, there must also be supply cables! be guided along the dashboard. After all, attaching such devices is also a source of injury in the event of heavy braking and accidents.

A radio receiver is already known from DE 196 43 282 A1, the removable control panel of which is designed as a radio telephone. After removing the control panel, the radio receiver is protected against theft. The removed control panel can then be taken along and used like a mobile phone. The disadvantage is that the functionality of the radio receiver is inextricably linked to the mobile phone, which means that the control unit must either have control elements for the radio receiver (for example FM / AM / CD) that lead to a certain unwieldiness of the radio telephone, or the operation of the radio receiver - Gers is complicated by the lack of these buttons ..

DE 199 59 307 A1 describes a navigation device which is functionally coupled to a special mobile radio device via an adapter interface. In the case of coupled operation in a motor vehicle, functional units from the navigation device and mobile radio device, such as, for example, display and input unit, are used jointly. at Removing the mobile device from a motor vehicle, there is a radio link between the adapter interface in the motor vehicle and the mobile device, which enables the user to determine his current location. The shared use of functional units is certainly advantageous. However, it is disadvantageous that a further mobile radio device in addition to the usual mobile radio telephones will hardly meet a real need.

Presentation of the invention. Task, solution. benefits

The invention is based on the object of eliminating the disadvantages of the previously known accommodation of the devices mentioned at the outset and of providing a simple and aesthetically appealing solution which can be expanded functionally compared to the individual functions of the devices.

According to the invention the object is achieved by the features of claims 1, 6, 7 and 8. Appropriate embodiments are the subject of the subclaims.

According to this, a hands-free device for a mobile radio telephone and a vehicle navigation device are combined to form a communication system, in that an area of the housing of the vehicle navigation device is designed for the form-fitting reception of a mobile radio telephone, with at least one connection to the amplifier and loudspeaker when the mobile radio telephone is inserted, and moreover if required to the supply voltage and / or an antenna and / or a data bus of the vehicle navigation device and / or an independent connection of the navigation device to the radio telephone network, which enables the navigation device. ^r This enables hands-free calling via the audio system of the vehicle navigation device. A number of other functions are also possible:

- Use of the display of the vehicle navigation device;

Connection of the mobile phone to a combination vehicle antenna for radio, mobile phone and GPS reception;

- Use of the telephone keypad for special functions of the vehicle navigation system (e.g. entering numbers);

Sharing of a personalized address memory by mobile phone and car navigation device;

- Use of the mobile phone by the navigation device for Internet access to update the data on the navigation road map;

Use of the mobile phone by the navigation device for dynamic navigation in order to load current traffic information, such as traffic jam reports, into the navigation system via a telephone service connection and thus enable a traffic jam-free route calculation ∑u;

- Use of the mobile phone by the navigation device for an accident emergency call with position information;

Integration of functions of other devices in the mobile phone, for example an adaptable remote control for controlling a gate operator and / or an in-house alarm system; Use of the mobile phone to secure the theft of the vehicle navigation system.

When sharing a personalized address memory, several partners who use the same motor vehicle sequentially each receive a personal mobile phone with its own phone number that is activated for the navigation system. This is recognized by the navigation system when it is inserted, whereupon the corresponding telephone address memory is automatically used as the destination memory for navigation.

With the integration of the mobile radio telephone, an internal mobile telephone for the navigation device can thus be dispensed with.

The invention also includes data carriers or processors provided with appropriate program technology, which enable the mentioned shared use of the database data or the control of common and overarching functions of the mobile radio telephone and vehicle navigation device, such as display, antenna use, keyboard operation and theft protection.

Further preferred embodiments of the invention result from the features mentioned in the subclaims.

Brief description of the drawings

The invention is explained in more detail below in an exemplary embodiment with reference to the accompanying drawings. Show it:

1 shows a control panel of the communication system according to the invention; Fig. 2, the control panel with the mobile phone removed and

Fig. 3 is a block diagram of the communication system.

Best way to carry out the invention

As shown in FIGS. 1 and 2, a bracket 3 is provided in the control panel of a vehicle navigation device 1, into which a mobile radio telephone 2 can be inserted and positively fixed there. When the mobile radio telephone 2 is inserted, a connection to the vehicle navigation device 1 is established via a plug connector 4, which at the same time provides anti-theft protection in the manner of a release panel, i.e. the vehicle navigation device 1 and an integrated car radio can only be put into operation when the mobile radio telephone 2 is inserted , The operation of the system with any mobile phone of the same type can be prevented or also released by additionally querying a telephone identification via the data bus.

Fig. 3 shows the function of the system using a block diagram. Mobile radio telephone 2 and vehicle navigation device 1 are connected by connector 4 with regard to the supply voltage, a data bus, an antenna connection and the telephone audio input / output. The system can switch the loudspeakers from radio operation and the microphone from voice input to hands-free mode during telephone operation via a switch in the vehicle navigation device 1. Data can be exchanged between the mobile radio telephone 2 and the vehicle navigation device 1 via the data bus, so that, for example, the display of the vehicle navigation device 1, which is easier to read for the driver, can also be used during telephone operation. Conversely, operating functions can be transferred to the keypad of the cellular phone 2 (eg entering numbers). The address memory of both device units can be used together, so that the driver can access the address database in his mobile phone 2, for example when navigating.
