`MOTOR VEHICLE HAVING A VEHICLE
`ELECTRONICS SYSTEM, INTERFACE FOR
`THE VEHICLE ELECTRONICS SYSTEM
`AND A METHOD FOR OPERATING THE
`VEHICLE ELECTRONICS SYSTEM
`
`FIELD OF THE INVENTION
`
`The present invention relates to a motor vehicle having a
`vehicle electronics system. The present
`invention also
`relates to an interface for a vehicle electronics system of a
`motor vehicle. The present invention further relates to a
`method for operating a vehicle electronics system of a motor
`vehicle.
`
`BACKGROUND INFORMATION
`
`With the arrival of personal computers (PCs) in private
`households,
`there are now also proposals to provide a
`computer, called a car PC, in a motor vehicle. These car PCs
`are designed to be installed in a DIN compartment for a car
`radio and to include the functionality of a car radio or
`extensive functions that are generally described as driver
`information systems (FIS functions), such as the function of
`a navigation device or Global System for Mobile
`Communications(GSM) telephone. In this manner, the vari-
`ous FIS functions, combined in a single device (car PC), are
`accessible via a single joint user interface. However, such
`car PCs lie in a high price category and are only usable for
`the special purpose for which they are designed. Universal
`applicability, as is the case with conventional personal
`computers (PC), is out of the question in the case of car PCs.
`
`SUMMARY OF THE INVENTION
`
`It is an object of the present invention is to improve a
`motor vehicle, an interface and a method of the aforesaid
`type to the effect that ease of operation and functionality are
`improved without at
`the same time having to develop
`special, cost-intensive computer design approaches.
`The above and other beneficial objects of the present
`invention are most effectively attained by providing a motor
`vehicle with an electronics system that includes an interface
`for connecting the electronics system with a personal com-
`puter. The personal computer (PC) is connected to the
`vehicle electronics system so that a vehicle user can operate
`the vehicle electronics system from the PC and/or can
`operate the PC from a user interface of the vehicle electron-
`ics system. That is,
`the respective functionalities of the
`vehicle electronics system and the PC are made available
`reciprocally.
`One advantage of the present invention is that a link may
`be established between conventional PC technology, par-
`ticularly the hardware and software commercially available,
`and vehicle technology, whereby the PC is able to obtain
`vehicle data and, conversely, the vehicle technology obtains
`access to up-to-date hardware and software, so that
`the
`functionality of the PC and/or the motor vehicle is increased.
`The integration of the PC into the motor vehicle gives the PC
`access to vehicle functions such as vehicle data, diagnostics,
`on-board computer, and gives a computing device
`integrated, for example, in the dashboard and having a user
`interface such as an operating element, a display, or the like,
`access to the PC having the up-to-date hardware and soft-
`ware of the connected PC that are provided by the respective
`vehicle user. PC technology with respect to hardware and
`software, already existing or developed in the future, is fully

`usable immediately in the motor vehicle. All innovations in
`PC and communications technology in the field of hardware
`and software can also be implemented immediately in the
`vehicle without intervention in the vehicle. A cost advantage
`is thus achieved in comparison to the permanently installed
`car PC, and synchronization or compatibility problems
`between the office/home PC and the car PC are avoided.
`New and individual functions,
`the scope of which the
`vehicle user himself can determine, are constantly able to be
`implemented in the motor vehicle. This is achieved by a
`specific connection of the vehicle electronics system to the
`newest PC technology, both with regard to hardware and to
`software. Special PC software for PCs integrated according
`to the invention into the motor vehicle brings a new market
`for software manufacturers.
`
`the
`According to one aspect of the present invention,
`personal computer (PC) is a mobile or portable PC such as,
`for example, a notebook PC, a sub-notebook PC, a palmtop
`PC, a personal digital assistance (PDA) or a laptop PC.
`In one embodiment, the vehicle electronics system has a
`first user interface with a first display device,
`the PC
`interface of the vehicle electronics system being designed so
`that, in addition to the motor-vehicle functions, the PC is
`also operable via the first user interface of the vehicle
`electronics system, and a screen output of the PC is effected
`via the first display device of the user interface of the vehicle
`electronics system, PC functions also being accessible from
`the first user interface of the vehicle electronics system.
`Furthermore,
`the PC has a second user interface with a
`second display device,
`the PC interface of the vehicle
`electronics system being designed in such a way that, in
`addition to PC functions, motor-vehicle functions are also
`operable via the second user interface of the PC, and a screen
`output is effected via the second display device of the PC. In
`this context,
`the screen output of the PC is preferably
`effected both via the first display device of the vehicle
`electronics system and via the second display device of the
`PC.
`
`For example, the motor vehicle has a vehicle PC (VPC)
`with a display device and an operating element,
`the PC
`interface being constructed on the VPC. To prevent unau-
`thorized access to the VPC via, for example, a mobile
`radiocommunication link connected to the PC, a firewall is
`integrated in the VPC.
`To connect the PC in a simple and functionally reliable
`manner, provision is made between the PC interface of the
`vehicle electronics system and the PC for a docking station,
`into which the PC can be releasably inserted for the con-
`nection to the vehicle electronics system.
`For example, the PC interface is a plug-in connection or
`a wireless connection.
`
`In addition, a connection of the PC to a power supply of
`the vehicle electronics system is provided for the energy
`supply of the PC in the motor vehicle.
`For example,
`the vehicle electronics system includes
`various control units, such as the engine control unit, trans-
`mission control unit, drive train control unit, vehicle elec-
`trical system control unit, door control unit, a car radio
`and/or a driver information system, a mobile radiocommu-
`nication unit or mobile cellular phone, a diagnostic tool,
`vehicle data sensors and/or vehicle environment sensors, a
`communications device (vehicle-vehicle or vehicle-
`infrastructure) for the exchange of data, e.g., automatic toll
`collection, access authorization, a heating/air-conditioning
`system with corresponding control units, an instrument
`cluster designed, for example, as a freely programmable

`display, one or more displays and/or a GPS navigation
`device. This vehicle can likewise be provided with devices
`which derive settings for various control units from maps or
`navigational data. In addition,
`the PC and/or the vehicle
`electronics system has at least one communication interface,
`in particular GSM (Global System for Mobile
`Communications), GPS (Global Positioning System), DVB
`(Digital Video Broadcasting) or DAB (Digital Audio
`Broadcasting).
`
`BRIEF DESCRIPTION OF THE DRAWING
`
`FIG. 1 shows a schematic block diagram of one embodi-
`ment of a connection according to the present invention
`between a vehicle electronics system and a personal com-
`puter (PC).
`
`DETAILED DESCRIPTION
`
`As shown in FIG. 1, a vehicle electronics system 10 is
`connected via an interface 12, e. g., a controller-area network
`(CAN),
`to a vehicle PC (VPC) 14. VPC 14 includes a
`computing device 16, a display device 18 and an operating
`element 20, and, for example, is installed, possibly with
`further operating control elements, in a central console. The
`vehicle electronics system, otherwise not shown in greater
`detail, includes, in particular, an air-conditioning system, an
`engine management, an instrument cluster, and the like. A
`docking station 24 is connected to computing device 16 via
`a personal computer interface (PC interface) 22. Docking
`station 24 is used to accommodate a conventional personal
`computer (PC) 26 such as a notebook computer, so that this
`PC 26 is connected via docking station 24 to computing
`device 16 and, therefore, to vehicle electronics system 10.
`Thus, PC interface 22 permits the connection of an
`external PC 26 to VPC 14, it being possible to operate
`external PC 26 via operating element 20, and the PC output
`being displayed via display device 18 of VPC 14. PC 26 thus
`expands vehicle electronics system 10.
`PC 26 has a PC card interface 28, for example, according
`to the PCMCIA standard, for connecting communications
`components such as GSM (Global System for Mobile
`Communications), GPS (Global Positioning System) or
`DAB (Digital Audio Broadcasting), which are then addi-
`tionally available via VPC 14. A firewall
`that protects
`vehicle electronics system 10 from external unauthorized
`access, e.g., via the GSM, is preferably integrated in VPC
`14.
`
`The combination of VPC 14 and external PC 26, with
`access to corresponding vehicle-electronics components via
`interface 22, is able, for example,
`to cover the functions
`specified in Table 1.

`Table 1: VPC/PC Functions
`
`In Table 1, column 3 describes one possible distribution
`(partition) of functions between the VPC and the PC. It is
`essential that VPC 14 remain fully functional, even when
`external PC 26 is undocked and permit a vehicle user access
`via an appropriate user interface to the functions integrated
`in the VPC and connected devices. Those functions that are
`
`only possible in conjunction with external PC 26, such as
`route planning, are automatically available via the user
`interface of VPC 14 after PC 26 has been docked. For
`
`example, provision is made on VPC 14 for a key by which
`the vehicle user can switch into a PC mode, so that operating
`element 20 and display device 18 of VPC 14 become an
`operating element and a display device for external PC 26.
`In this case, for example, a graphic user interface (GUI) such
`as a windowing interface appears on display device 18 in the
`central console of the motor vehicle. External PC 26 can
`
`then be remotely operated by-appropriate operating ele-
`ments 20 of VPC 14.
`
`Alternatively, external PC 26 is connected by a device
`similar to docking station 24, or by a standardized interface
`(serial interface) via a plug connector or in a wireless, e.g.,
`infrared, manner. The interface connection to the vehicle
`electronics system can also be effected directly with the aid
`of a suitable interface such as CAN, without computing
`device 16. In this case, the communication with the outside
`world is performed either via communication interfaces
`(GSM, GPS, DVB, DAB, etc.) connected to or integrated in
`PC 26, or via communication interfaces (GSM, GPS, DVB,
`DAB, etc.) connectible to or integrated in the vehicle, or in
`a combination of communication interfaces of PC 26 and the
`
`vehicle. If communication components are implemented in
`PC 26,
`then they are preferably connected to a vehicle
`antenna, so that transmitting/receiving capacity possibly in
`the vehicle is boosted.
`
`New functions such as a driver’s log or diagnostics, which
`are really only created by the connection to the vehicle
`electronics system, are possible on external PC 26. A sepa-
`ration between vehicle-specific data that can or should be
`utilized by the vehicle owner, and data that should only be
`accessible for authorized groups such as vehicle
`manufacturers, suppliers, the garage, etc., can be imple-
`mented in a simple manner. In doing this, only the PC
`
`Page 4 of 6
`
`

`

`US 6,472,771 B1
`
`5
`interfacce of the present invention must be provided in the
`vehicle. In this context, the scope of the data provided by the
`vehicle can vary as a function of the vehicle equipment. The
`vehicle has no disadvantages whatsoever in its basic
`functionality, since this is fulfilled even when external PC 26
`is not connected. The utilization depends solely on the
`vehicle user. Furthermore, new or individual functions, the
`scope of which is determinable by the vehicle user and
`which are achieved by the connection in each case to the
`newest PC technology (hardware and/or software), can
`constantly be implemented in the vehicle.
`Furthermore, the present invention also allows an expand-
`able functionality of vehicles that have no VPC 14. Avehicle
`user does not have to decide immediately upon purchase of
`the vehicle whether he wants VPC functionality, since he
`can “retrofit” this later himself by the simple connection of
`an external PC 26.
`
`External PC 26 is preferably connected to a power supply
`of the vehicle, such as, for example, the car battery. Data
`input to vehicle electronics system 10 and data output from
`vehicle electronics system 10 are possible via PC 26. It is
`possible to implement additional functions such as accident
`recorder, diagnostics, driver’s log or the adjustment of the
`vehicle to individual characteristics such as body size for the
`seat setting, limitation of the highest possible speed, etc. The
`access and/or utilization authorization like, for example,
`restricted utilization region only within the national
`boundaries, in a scope definable by the vehicle owner such
`as the car-rental firm or car-sharing company, can be imple-
`mented by suitable software installed on PC 26.
`The data input/output can also be effected by speech, for
`example, with the aid of devices existing on PC 26, or with
`the assistance of devices existing in the vehicle such as
`loudspeaker, microphone, and speech preparation for PC
`interface 22. Acombination of such devices of PC 26 and the
`
`vehicle is also possible.
