Description

The The invention relates to a tachograph according to the preamble of the claim 1. In addition, the invention relates to one with such Tachograph equipped arrangement and an executable with it Method for transmitting driver and / or vehicle related Data from the tachograph to an external device.

The modern tachograph is an instrument for installation in a vehicle, in particular a commercial vehicle, which stores driver and / or vehicle-related and other data digitally in an internal memory and an interface for transmitting the driver and / or vehicle-related data to external devices, in particular Storage devices in the form of z. B. so-called. Download sticks or -Keys has. This is on the WO 2006/000507 A1 referenced, in which such a tachograph is described. This has on its front panel an interface into which such a download stick can be plugged to load the data, in particular the driver and / or vehicle-related data from the tachograph.

Because with the introduction of digital tachographs have the haulage companies the legal obligation to keep the tachograph data within given To download and archive deadlines. To do this But they first by means of the tachograph authenticate their company card. Only then can they have a special download hardware, d. H. above the so-called download stick or a computer with the appropriate download software is equipped, the data Download. Downloading data may vary depending on the data size take several minutes. During this time, however, must the company card remain in the tachograph. Downloading The data is therefore very time consuming. As a company in the Usually owns only a single company card, the download can in several vehicles only one after the other. Likewise there is Companies whose vehicles within the specified deadlines not to return to the fleet center and therefore also not available for data download. Thus arises a lot of time with high costs. It results the development goal for improved solutions search.

In front this background, new tachographs are currently under development, in which the data by means of a standardized protocol, the so-called "Remote Download Protocol ", to external devices or to be downloaded. This protocol is in accordance with "Digital Tachograph Specification for remote company card authentication and remote data downloading "the" Heavy Truck Electronic Interfaces Working Group. "This protocol is intended to provide a comfortable Remote data retrieval via external networks be, with the data z. B. via mobile via a GSM connection be transmitted to the company. The connection of the Tachographs to external networks takes place via a Connection to the so-called CAN bus and the board computer of the vehicle. The new remote query technique has the advantage of having the company card no longer plugged directly into the tachograph for authentication but the authentication needs to be removed over The remote download protocol can be done using the company card z. B. in a personal computer or a card reader on Location of the company is located. In addition, the download can during the ride, so that the time required significantly reduced. However, due to the GSM connection additional Data-transmission costs.

at These known solutions are therefore created for the Hauliers either indirect costs by the time spent with a direct download in the vehicle or direct costs through the data transmission via remote download. There is therefore the desire for one for the user comfortable solution that does not have these disadvantages has and for both direct and indirect data download suitable is.

Therefore It is an object of the invention to provide an improved tachograph create, which overcomes the above problems in an advantageous manner. Likewise, an arrangement equipped with it as well as an executable therewith Method for transmitting driver and / or vehicle related Data from the tachograph to an external device proposed become.

Solved The task is performed by a tachograph with the characteristics of Claim 1 and by an arrangement or a method with the features the corresponding independent claim.

Therefore a tachograph is proposed, the driver and / or vehicle-related Digitally stores data in an internal memory and an interface for transmitting the driver and / or vehicle related Data to external devices, the interface one on the front panel of the tachograph freely accessible configured interface is responsible for a transmission of authentication data and for a dependent transmission the driver and / or vehicle-related data is set up.

In addition, an inventive arrangement with such a tachograph and with a proposed external device, wherein the interface is a freely accessible on the front panel of the tachograph interface, which is set up for a transmission of authentication data and for a dependent transmission of the driver and / or vehicle-related data.

Also becomes a method according to the invention for the transfer of driver and / or vehicle related data from such a tachograph proposed to an external device in which the transmission over one on the front panel of the tachograph freely accessible configured interface takes place, with a transmission of authentication data from this external device or another external device to the tachograph and, depending on that, a transmission the driver and / or vehicle related data from the tachograph to this external device, to the other external device and / or to another external device becomes.

By The invention is therefore a tachograph created that a very user-friendly interface provides with the front Connections to external devices are easy to produce, for both authentication and data transmission to carry out. It is possible, in particular the authentication via remote access via remote Devices, especially card readers via GSM, perform. All functionalities can be over the front-mounted hardware and software are realized, so that in particular the use of a board computer can be dispensed with is. The proposed invention is therefore particularly cost-effective realizable.

These and further advantages will be apparent from the dependent claims.

Therefore it is beneficial if the interface is for a transmission the authentication data and the driver and / or vehicle related Data according to a normalized remote data retrieval protocol, in particular according to the so-called. Remote Download Protocol, is set up. In this The interface can also be related to a transmission Data lists are used to indicate the nature and / or extent of the data download pretend.

Preferably is the interface as a serial interface, especially as So-called RS-232 interface, designed to be easy and without Additional expenditure external devices, such. For example, external storage devices or memory sticks and / or external personal computers to be able to.

The Interface may be preferred for connecting an external device, in particular an external storage device, set up be a wireless module for wireless transmission of Authentication data and the driver and / or vehicle related Contains data.

Preferably The tachograph contains a control unit that over the interface checks authentication data received from an external device and depending on the interface for transmission the driver and / or vehicle-related data for a predetermined Time span, the z. B. 24 hours, unlocked.

With the aid of the invention, it is possible, in particular, to make the complete remote download protocol or its functionalities easily accessible to the user via the front-side interface of the digital tachograph. As an alternative to a serial RS-232 interface, the so-called diagnostic interface (K-Line nach ISO 9141 ) and modified as a download interface. With the invention, all download tools can use the possibilities and advantages of the Remote Download Protocol and, in particular, also carry out the authentication via this protocol. Thus, the company card can also be removed or removed after the authentication and the time-consuming can be done without the card itself. The card can thus still be used while the download is running for another download in another vehicle.

Because the authentication is an activation for the download within a certain time window of z. B. effect 24 hours can, needs the company card only once before in one internal card reader (chip card slot) of the tachograph or over an external card reader to be plugged in, and then the download list will be transferred to the tachograph can. Is the time slot after a successful authentication Once opened, the company card can again be removed from the card reader. The download of the data itself, in particular the driver and / or vehicle-related data, then takes place in accordance with the Download list and can at any time within the 24th h time window are performed, including during the ride.

The present invention and the advantages thereof now described in more detail with reference to exemplary embodiments, with reference to the accompanying drawings, which represent:

1 shows a first embodiment of an arrangement with a tachograph according to the invention;

2 shows on the basis of sub-figures a) to c) executed on the tachograph first operation process for data download of driver and / or vehicle-related data;

3 shows on the basis of sub-figures a) to d) executed on the tachograph second, alternative operation process for data download of driver and / or vehicle-related data;

4 shows a flowchart for a method according to the invention.

The 1 shows a first embodiment of an arrangement 1 with a tachograph 2 on his front panel 4 has several functional and operating elements. These include, among other things, an advertisement 7 , various controls 6 and a printer drawer 5 , In addition, the tachograph points 2 on its front panel 4 a slot for an internal card reader 9 on. Here is a dedicated authentication card, especially the driver card 19 or the corporate card 32 to be introduced. According to the invention, the tachograph 2 now on his front panel 4 a special interface 8th on, which is set up both for the transmission of authentication data A and of driver and / or vehicle-related data D. In this example, the interface is considered a serial port 8th In accordance with RS232, in the form of a socket for receiving a corresponding plug 11 , The plug is part of an external storage device, for example 3 which also has an R-232 interface 10 features. By plugging in the external storage device 3 creates a plug connection 13 , so that data z. B. according to the Remote Download Protocol directly between the tachograph 2 and the external storage device 3 can be exchanged.

In this example, this is the external storage device 3 designed as a plug-in module or stick, in which also a wireless module 14 is integrated with an external mobile network 21 via a corresponding radio connection 20 Exchange data with other external devices. The stick 3 thus serves not only as a pure storage device, but also as a connection element or relay for remote transmission of data between the tachograph 2 and any external device to which z. B. over the mobile network 21 and optionally via other networks (for example, DSL) can be made a connection.

In the in 1 The example shown connects to a personal computer 30 manufactured as an external device for data exchange over the network 21 and the stick 3 as well as the interface 8th communicating with the tachograph. The personal computer 30 For example, it is located at the company's headquarters where it is operated at the headquarters to remotely query all vehicle fleet tachographs. For example, if the illustrated tachograph 2 be queried, this can be done thanks to the invention by means of the so-called. Remote Download Protocols. There is a card reader 31 Connected to the personal computer, so from the into the card reader 31 introduced entrepreneur card 32 the authentication data A read and the connection established to the tachograph 2 can be transmitted. Also, from the personal computer 30 Data lists DL are transmitted which indicate which driver and / or vehicle-related data D from the tachograph 2 to be queried. After successful authentication, the tachograph is enabled for the actual data query or data download. Preferably, the activation applies only for a predetermined period of z. 24 hours. Within this period then arbitrarily the driver and / or vehicle-related data D and other data on the said connection to the personal computer 30 be transmitted. This data D can also initially only stick to the memory 3 transferred and stored there locally.

It is thus easily possible to carry out only the authentication initially and later, within the time window enabled, a direct or indirect data transmission from the tachograph 2 to the memory stick 3 or to any other external device.

Based on 2 Now, a first example of a data download operation will be described. Based on the sub-figures a) to c), the sequence of a possible procedure for data transmission and data downloading by means of the inven tion to the tachograph 2 provided interface 8th illustrated.

First, to the interface 8th an external device, here a laptop 30 ' , connected to carry out an authentication. The laptop, for example, with a serial interface cable to the tachograph 2 over on the front panel 4 attached interface 8th connected. The laptop 30 ' has an internal or external card reader, in which the business card 32 is introduced. As shown in the sub-figure a), then the transmission of the authentication data A and the transmission of the data list DL to the tachograph 2 ,

After successful transmission of the authentication data A and the data list DL, the entrepreneur card 32 be removed again. Likewise, the laptop can 30 ' are removed, as illustrated by the sub-figure b).

Now the tachograph 2 for a given period of time of z. B. 24 hours unlocked. Within this period, a data download can be made to any of the tachographs 2 connected device done.

As shown in sub-figure c), the data D can be sent to a remote external device, such as the personal computer 30 , be transmitted. This is the already described GSM connection 20 over the mobile network 21 built up. Alternatively or additionally, the data D can also be obtained directly from the tachograph 2 over the interface 8th in the memory of the stick 3 to be written. This can be done while driving. It is not necessary the entrepreneur card 32 in the tachographs 2 insert. Rather, the data exchange or the download of the data D can be arbitrary, as long as the time window is still open.

In 3 Now another example of a data download process is shown, wherein the sub-figures a) to d) reproduce corresponding snapshots of the individual steps.

As the subfigure a) shows, the entrepreneur card is first used for authentication 32 directly into the card reader of the tachograph 2 plugged in.

Then an external device, here the laptop 30 ' , over the interface 8th with the tachograph 2 connected to transmit the data list DL, which is shown in the sub-figure b). Upon successful authentication and transmission of the data list, the time window is opened.

As the subfigure c) shows, the corporate card 32 then from the tachograph 2 be removed.

The tachograph 2 is unlocked, so that at any time while the time window is still open, for example, the memory stick 3 into the interface 8th can be plugged in to perform a download of data D. This is shown in subfigure d). The data D is then downloaded in accordance with the previously transmitted data list DL, preferably via the said remote download protocol.

The 4 schematically shows a flowchart of a method according to the invention 100 with the steps 110 to 192 , With the help of the illustrated method 100 an inventive data download from the tachograph is performed in any external device. The following description also takes on the 1 Reference.

In a first step 110 First, the company card 32 in the tachographs 2 introduced. Then in one step 120 checked if the tachograph 2 in the so-called Company Mode. This means that it checks if the tachograph 2 is ready for downloading driver and / or vehicle-related data D according to the remote download protocol RDP. In particular, the authentication is based on the company card 32 carried out.

If authentication is successful, a next step follows 130 , If the authentication is not successful or is the tachograph 2 not in the so-called Company Mode, so on the step 110 jumped back.

After successful authentication is in step 130 the download list DL on the tachograph 2 transfer. Then follows in the step 140 Opening the time window, which is preferably 24 hours.

In a next step 150 can the card 32 from the tachograph 2 or an external reader 31 be removed. The tachograph 2 is now enabled for a period of 24 hours for a data download.

In a later step 160 the production of a compound takes place 13 between the external storage device or download stick 3 with the tachograph. In the simplest case, the download stick is in the interface 8th of the tachograph 2 plugged in. Then in a subsequent step 170 a data request through the download stick 3 respectively.

When requesting a data download is in one step 180 First checked, if the given time period of 24 hours has already expired. If this is the case, then the step follows 190 , in which then a download is denied. If this is not the case, then the step follows 191 in which it is then first queried whether there are data in the data list DL. If so, the step follows 192 in which the data D according to data list DL in the download stick 3 downloaded.

If the data list contains no data, then the step goes 191 back to the step 190 , so that the denial of a download occurs. If the download was finally denied or the data D was successfully downloaded, then this is the procedure 100 completed.

In summary, the invention provides an easy-to-use interface for a data remote-controlled data download. In particular, the Remote Download Protocol and the corresponding functio nalities via an interface on the front of the device tachograph easily and directly made accessible. Since the invention is preferably implemented in a standard-compliant interface (eg, RS-232), any hardware capable of communicating with that interface may, in principle, also use the Remote Download Protocol for communication. Accordingly, this hardware then the extended possibilities of a remote download are available, which z. B. the corporate card is required only for authentication. This results in many new download options. So z. B. a hardware or a module for short range transmission (such as infrared or Bluetooth) can be used to perform a download of all vehicles in the yard, without each vehicle must be visited personally and without any cost by a GSM data connection arise.

If by modification according to the invention the remote Download Protocol via the K-Line diagnostic interface on the front of the device, can any hardware that is capable with this interface to communicate, in principle also the remote Protocol for Use communication. It would thus z. B. a combination of diagnostic device and download device conceivable.

Furthermore is in the so-called company mode of the tachograph, so if a company card for Authentication is plugged in, transferring the download list also used to cause the start of the time window by preferably the timeout specified in the Remote Download Specification Tauth is used. The timeout is made by dragging or removing the company card from the tachograph not finished. To download the Data according to the download list can now within the time window Tauth any download hardware used become. It is conceivable that the download over the remote Protocol is carried out or via the direct Download protocol. There are only minor changes necessary in the software of the download tools and there are none additional hardware costs, because the existing hardware (Download stick or key, card reader in the tachograph) used can be. A company employee could be on this way open the download timeslot and then the driver give a download stick or key. The driver needs this then only in the course of the day, z. B. in a break, on connect the tachograph. After the end of the shift he can then submit the download stick or key back to the company.
