    Descri tion Digital tachograph The invention relates to a fïigital tachograph into which atachograph card can be inserted.
    A digital taohoqraph is used in vehicles to record, for example, driving' periods and rest periods, interruptions ihdriving periods, additionally driven kilometers and a speed atwhich driving has oconrred, The digital tachograph, inparticular an EU~digit;l tachograph, stores the recorded data,inter alia, eaternally on taohograph cards. These taohographcards include driver cards, control cards, company cards or workshop cards.
    A driver card serves, for examnle, to enable a driver to provehis identity to the tachograih, The driver card contains, forexample, the driving activities of the driver over the last few weeks. A control card per' :its access rights to data which isstored in a memory of the digital tachograph and said card isused, for example, for police checka. A workshop card is usedby a workshoç to eonfigure the digital tachograph, for exampleto be able to make certain settings to the tachograph, Acompany cart is assigned to a specific company and can be usedto read ont that data from the memory of the tachograph which relates to journeys made for the company.
    The data which is stored on the cards is protected against datamanipulation by corresponding technical means. In order toensure the data security, the taohographs have a validityperiod, Furthermore, the data contains a security certificatewith a further validity date, As soon as the validitv period of a taohoqraph expires, said card is only accepted for reading purposes by the tachograph,Carde with an expired validity date can no longer he used bythe tachograph to store new data. Only the data which is stored on the tachograph card can he read out.
    For the driver* of a vehicle, for example a truck, with adigital 'tachograph, this results in disadvantages for dailyuse, The obligation to prove onefe identity with respect toactivities carried out in the course of a traffic controlrequires an old tachograph card with an expired validity dateof the card or of the security certificate to he carried on theperson until a history of a specific number of days, forexample a history of 28 days, is secured on the new tachographcard. lf a taohoqraph card has expired, a driver is thereforeforced initially to carry on hie person both the old and thenew tachograph cards for a certain time. Both cards have to beproduced at a check and are evaluated hy the checkinq officere.A taohograph has, inter* alia, the function of providing adriver with recommendations relating to his future driverbehavior. In this context, for example, compliance with theEuropean Driving Time and Rest Period Regulation can he takeninto account. So that the tachograph can provide the driverwith the corresponding recommendation for his individualdriving periods and rest periods, it is necessary for thetachograph to evaluate the driving activities of a precedingtime period. However, if the tachograph card, in particular thedriver .ard, which is being operated in the tachograph has beenin use only for a short time, the card lacks driving data whichpermits the tachograph to evaluate a relatively long precedingtime period with, respect to the driving activities of 'the Qlflïïêff .
    For this situation, the tachograph carries out a function whichis based on certain exceptione, in order to be able to carryout the necessary calculations, at least to some degree, in order to suggest a future driving behavior, however, the smaller the extent of the historical data which isnecessary for the evaluation of the driving behavior, the moreimprecise will the prediction or recommendation with respect tothe fiture driving behavior by the tachograph also turn out tohe. Although this is cowmunicated to the driver on a display ofthe tachograph by .means of specific information, it is notwithin the sense of the functionality which is actually implemented, The ohject of the present inventicn is to specify a digitaltachcgraph with which the handling of a tachograph card can he made easier, An emhodiment of a digital tachoqraph with which a tachographcard can he handled_ easily, in. particular when. a validityperiod of the tachograph card or of the security certificate ofthe tachograph card expires, is specified in patent claim l.According to one emhodiment, the digital tachograph comprisesat least one slide~in compartment for the insertion of atachograph card and a ontrol device for reading out data fromthe tachograph card. The control device is designed to read outdata from a first tachograph card and to store it on a secondtachoqraph card which is different from the first tachograph card.
    As soon as a new tachograph card, i,e. a tachcgraph card with anew validity date, in particular a driver card, is pluqged int the digital tichograph, the control device of the tachograihcan transfer or copy data from the old tachograph card, i.e.the tachograph card with the expired validity date, to the newtachograph card. The tachograph can have, for example, a display device, with the result that, hy means of a specific menu, the driver can he provided with the possibility of all oronly relevant data from the old taehograph card, for examplethe old tachograph car., to the new tachograph card, for example the new driver card.
    The tachograph card generally has a validity date which relateeto the card itself and is set in the course ef thepersonalization by a responsible authority and has a validitydate of a security Certificate or security key which iecontainedt in the card, The validity period. of the securityoertificate ia typically longer than the validity period of the card.
    The control device of the digital taehoqraph can be designed todetect whether the eecurityd features on the old tachographcard, for example the eld driver card whose validity period hasalready expired, are still valid, If the control device detectsthat the validity date of the security features of the expiredtachograph card have not yet expired, the tachograph can trustthe data etored on the card and can transfer eaid datacompletely to the new tachograçh card. The new tachogreph cardtherefore has available all, or at least a eufficient quantity,of data of the respective driver. The control device of thedigital tachograph oan output recommendatiens, for example apredictieh of driving periods and rest perioda, hy evaluatingthe relatively old data, these driving periods and rest periodshaving a high level of reliahility since euffieient data from the past ie available to the c ntrol device for evaluation, lf the control device of the digital taehograph detecte, forexample, that the securitj features of the old expiredtachograph card are not longer valid, the tachograph can nolonger trust the data atered on the old card, ln this oaee, thedigital taohograph can offer 'the driver* the possibility, hymeans of a correaponding menu, of transferrihg at least thedriving activities, for example the driving periode and rest periods with the attribute “unknownf to the new tachograph 1m2 card. In this case, although these time periods are from thelegal point of view “unknown” and can therefore not he takeninto account in a driver control, the past activities of thedriver in a preceding time period, which are transferred fromthe old tachograph card to the new one, can he used by theditital tachoqraph to analyze and. therefore predict drivingperiods and rest periods which are to he recommended in the IUÉUKG, The invention is explained in more detail below with referenceto figures which show exemplary embodimente of the invention.
    In the drawings: Figure 1 shows an emhodiment of a digital tachograph, and Figure 2 shows a flowchart of the transmission of data between tachograph cards.
    Figure 1 shows an embodiment of a digital tachograph 100 withwhich data can be transmitted from en old tachograph card withan expired validity date to a new tachograph card, The digitaltachograph 100 has at least one slide~in compartment ilfia, 11Übfor the insertion of a tachograph card 10, 2G. Furthermore, thedigital tachograph has a control device 120 for reading outdata from the tachograph card 1%, 20, The control device 120 isdesigned to read ont data from a first tachograph card lÛ andto store it on a second tachoqraph card 20 which is different from the first tachograph card, The validity date of the first tachograph card 1% or thevalidity date of the security certificate of the firsttachograph card 1G may already have expired, with the resultthat the oid tachograph card lÜ can now only he evaluated in areading fashion hy the tachograph 100. In contrast, the secondtachographi card 20 has a validity date which. has not yet expired. The control device 120 can he designed to detect the respective validity date of the first and second tachograph cards lfi, 29, According' to one emhodiment of the digital tachograph, the control device 120 can he designed to read ont the data from the first tachograph card 10 wii the expired validity date andstore it on the second, new tachograph card 20 if the controldevice 12Û detects that the validity date of the firsttachograph cards has expired, and the validity date of thesecond tachograph card 20 is a more recent date and has not yetexpired. The digital tachograph 100 can have, for example, amemory device 130 on which the data which is read out from the first tachograph card 10 can be buffered_ According to a further embodiment of the digital tachograph,the control device 12% can. be designeda to detectt whether arespective validity date of a security certificate of the firstand second tachograph cards 10, 2G has expired. The controldevice l2Ü can be designed to read out the data which is storedon the first tachograph card 10 and store it on the secondtachograph card 20 if the control device 129 detects that therespective validity date of the first tachograph card 19 hasexpired and the validity date of the security certificate ofthe first tachograph card. 10 has not yet expired, and therespective validity date of the second tachograph card 20 andthat of the security certificate of the second tachcgraph card 2G have not yet expired, According to a further possible embodiment of the digitaltachograph, the control device 120 can be desithed to read outthe data from the first tachograph card QÜ and store it on thesecond tachograph card 29 while adding an attribute, if the control device w 120 detects that the respective validity date of the firsttachograph card 10 and tha: of the security certificate of thefirst tachograph card 19 have expired, and the validity date ofthe second 'tachograph_ card. 20 has hot yet expired, and. thevalidity date of the security certificate of the secondtachograph card 2G has not expired, The attribute which thecontrol device l2O adds to the data which has been read outfrom. the first 'tachograph_ card, 10 and. stored on 'the secondtachograph card 20 characterizes the invalidity of the securitycertificate of the first tachograph card. The data which isread out can continue to he evaluated by the control device 120for the predictioh of driving periods and rest periods,however, the data which is characterised, for example, with theattribute “n known” can no longer be used for submission during a control.
    According to a further possible emhodiment of the digitaltachcgraph, the digital tachograph has a display device l4Û.The control device 126 can be designed to output display dataon the display device 140, said display data indicating to adriver that the validity date of the first tachograph card 10has expired if the expiry of the validity date of the first "P1" tachograph card 10 has been detected by the control device lea.
    The control device l2O can he designed to display a request toinput input data on the display device låü if the eapiry of th.validity date of the first tachograph card 10 has been detectethy the .ohtrol device 129. The control device 120 can bedesigned to read out the data from the first tachograph card 10as a function of the input data which is input, and to storesaid data on the second tachograph card 20. Therefore, a drivercan, for example, select, hy means of a menu which is displayedon. the display device 140, whether data. is copied from: the expired tachograph card to the new taohoqraph card. The driver can select, for example,old tachograph card is read out completely or only whether the partially.
    The control device 129 can he designed, in particular, to readout the data from the first tachograph card 10 with anti-manipulation protection and store the data on the secondtachograph ard 2G with anti~manipulation protection. The firstand second tachograph cards lO, 20 can he embodied, for example, as driver cards. ln th; text whioh follows, the transfer of data from the firsttaohograph card with the expired validity date to the secondtaohograph card 20 with the new validity date is explained withreference to figure 2, ln the method step 1, the new tachographcard 20 is firstly inserted inte the siidemin oompaftment llüa,ln the method step 2, the old tachograph card lö is fed into the slidewin oompartment ilüb. in a method step 3, the control device *.Ü detects that the validity date of the firsttachograph card 10 has expired and that a new tachograph card is inserted in the tachograph.
    Display data, which contains, for example, an enquiry to thedriver whether the control device 120 is to transfer the dataor at least some of the data which is necessary for aprediction of the future driving behavior of the driver fromthe first tachograph card lO to the second taehograph card ZSis subsequently displawed on the display device lêü, lf thedriveri wishes 'that the data should. be transferred. froni thefirst tachograph card lO to the second tachograph card 29 andmakes the corresponding input, in a method step 4 the data ofthe first, old taohograph car. lO is read out with anti~manipulation protection and huffered, for example, in thememory device llü. Subsequently, the data is stored in the new, second tachograph card 20 with anti~manipulation protection. in a næthod step 5, the old driver care is ejeoteä from theslide~in compartment liüb efter the ending of the reading outor eopying ef the data. The control device 120 can communicatete the dtiveti by* means of a corresponding display en thedisplay device 146, for example a display of the tachograph,that all the data, or at least the data which is relevant forthe predictien of the future driving getiods and rest periods,has been. successfully transferreá. from, the first tachograph fw card lO to the second tachograph card eü.
