Description

Field of the invention

The present invention generally relates to tachographs. In particular, the present invention relates to a tachograph that provides communication with a card device, and to such a card device.

Background

Analog tachographs have been used for a long time in order to keep record of driving routines of heavy vehicles such as trucks and buses. Such driving routines normally relate to driving speed of the vehicle. The speed of the vehicle is logged, usually during a 24 hour cycle, thereby also providing information as to whether the vehicle is moving or stationary.
In order to enhance the safety of road travel and to improve drivers' working conditions, digital tachographs were introduced some years ago to replace the analog tachographs. Digital tachographs typically record travel data associated with a specific driver by means of the driver identifying himself with a personal smart card that for instance can be a driver's license. Normally, the travel data is also written to the smart card. This way, control of a driver's driving habits can be evaluated both via the smart card, as well as by analysis of data stored in the tachograph.
Although the digital tachographs have provided improvements compared to the analog tachographs, there still exists several drawbacks with the presently available tachographs as well as with the driver cards for use with tachographs.

Summary of the invention

In view of the above, a general object of the invention is to provide a tachograph and an identification card associated with the tachograph that simplifies user interaction.
Hereto, in accordance with a first aspect of the present invention there is provided a tachograph comprising: wireless communication means adapted to receive data from identification units of a first type, and a memory operatively connected to the wireless communication means, wherein the memory is adapted to store data received by the wireless communication means from the identification unit of the first type.
By utilizing an appropriate data transfer protocol, faster data transfer speed may be provided compared to data transfer speed provided in currently available solutions between e.g. tachographs and smart cards. Beneficially, wireless communication between the tachograph and the identification card of the first type also provides simplified interaction between a user and the tachograph as the card no longer needs to be in physical contact with a tachograph for data communication between the tachograph and the card. Further, by providing wireless communication between the tachograph and an identification card of the first type, e.g. a driver card, the card may be subject to less wear and may consequently enjoy a longer lifetime.
One embodiment may further comprise communication means adapted to receive data from identification units of the first type. Hence, the tachograph may comprise two interfaces, i.e. the wireless communication means and the communication means, which each can communicate with identification units of the first type. An effect which may be obtainable thereby is that the tachograph may communicate with different interfaces of an identification unit of the first type via the two interfaces in the tachograph. In this case, the tachograph may provide secure verification of data transferred between the different interfaces of the identification unit of the first type, as will be further elaborated below.
The communication means may have wireless communication means for wireless communication with identification units of the first type. Hence, the tachograph may act as a secure link between e.g. two wireless interfaces of the tachograph.
One embodiment may further comprise card reading means adapted to physically interface with identification cards of the first type and with identification cards of a second type, and to exchange data with identification cards of the first type and second type, wherein the memory is operatively connected to the card reading means and adapted to store data received by the card reading means from identification cards of the first type and second type.
An effect which may be obtainable thereby is compatibility with identification cards of the second type such as for instance driver cards using smart card technology.
Beneficially, two-way communication is hence provided with identification cards of the first type, allowing users of the card of the first type to receive data from the tachograph.
One embodiment may further comprise coding means operatively connected to the memory and adapted to provide cryptologically secured data communication between the memory and the identification cards of first type and second type.
Thereby, secure handling of the data may be provided so that modifying data provided by the tachograph becomes more difficult. Hence, data relating to e.g. driving hours becomes more trustworthy.
The card reading means may have a card receiving slot being adjustable between having a first card slot dimension associated with identification units of the first type and a second card slot dimension associated with identification units of the second type. By providing an adjustable card receiving slot, cards having both e.g. a smart card portion and more advanced electronics comprising wireless communication means, and having a different card thickness than usual smart cards, may also be used with the tachograph.
One embodiment may further comprise processing means operatively connected to the wireless communication means, wherein the processing means is adapted to sign data received by wireless communication means and provide signed data to the communication means, which communication means is adapted to transmit the signed data to an identification unit of the first type. By signing data received from e.g. an identification unit of the first type, such data may be sent from a non-secure memory in the identification unit and may then be transmitted to e.g. a second, secure memory of the identification unit.
The memory may be adapted to store a plurality of user profiles, each user profile being accessible by an identification unit associated with that user profile. Thereby a user profile associated with a user may be accessed when a user identification unit has been verified to pertain to that profile. Beneficially, preferred user settings of that user may then be loaded from the memory, simplifying user interaction with the tachograph.
The memory may be adapted to receive software update data from identification units of the first type. Hence the tachograph software may be updated via an identification unit of the first type in a secure way upon the tachograph having identified the identification unit. Moreover, the identity of the user who provided the software update may be logged in the memory of the tachograph for further security.
According to a second aspect of the invention there is provided a card device for use with a tachograph, wherein the card device comprises: first processing means, wireless communication means connected to the first processing means, and a first memory connected to the first processing means, wherein the wireless communication means is adapted to transmit data stored in the first memory to the tachograph.
Beneficially, by providing a card device that may communicate wirelessly with a tachograph, the functionality of both the card device as well as the functionality of the tachograph may be expanded and providing a more user friendly interaction between the card device and the tachograph. For instance, the card device may no longer need to be in physical contact with a tachograph in order for data to be e.g. transmitted to the tachograph from the card device.
One embodiment may further comprise: second processing means, a second memory connected to the second processing means, and interface means connected to the second processing means, wherein the interface means is adapted to transmit data received from the second memory and to receive data from the tachograph by physically interfacing with the tachograph.
Thereby, the card device may be able to support additional ways to communicate e.g. with a tachograph.
The wireless communication means may be adapted to receive data from the tachograph. Hence, two-way communication between the card device and the tachograph may be provided.
Additional possible features and preferred embodiments are set forth in the appended claims and discloses in the following.

Detailed description

A tachograph 1 according to an embodiment of the invention is shown in Fig. 1. The tachograph 1, which is for the purpose to illustrate one example and should in no way be construed as limiting the scope of the invention, comprises a housing 3 comprising inter alia wireless communication means 5, a memory 7 that is operatively connected to the wireless communication means 5, processing means 9 operatively connected to the memory 7, and communication means 6, in the following referred to as a card reader 11, that is operatively connected to the memory 7. Tachograph 1 also comprises coding means 8, operatively connected to the memory 7, the processing means 9 and to card reading means 11. The processing means 9 is adapted to control the operation of the tachograph 1.The tachograph 1 in operation typically is connected to a commercial vehicle such as a truck or a bus (not shown). The tachograph 1 has at least one vehicle interface 13 which is in operative connection with the memory 7 via the processing means 9. The vehicle interface 13 can be brought in communication with a tachograph interface (not shown) of the vehicle. Such communication can be provided by wire or wireless connection with the vehicle. The tachograph 1 can hence receive information from the vehicle, which information for instance may relate to the speed of the vehicle. Thereby e.g. a freight forwarder company is able to log their drivers' driving routines.
The processing means 9 has a secure processing unit e.g. for reliable handling of driver identification, storing of authenticity certificates, storing of driving data (revolutions per minute) received from a gear box of a vehicle the tachograph 1 is installed into, via a secure motion sensor, and for digital signing of vehicle related data, i.e. functioning as a signing processor for signing vehicle related data. The vehicle related data includes inter alia driving data and driver activities.
The wireless communication interface provided by the wireless communication means 5 allows for wireless communication with an identification unit of the first type 17 such as a driver's identification card of a first type 17 adapted to wirelessly communicate with a tachograph. Wireless communication with a card of the first type 17 is to be construed as the wireless communication means 5 being adapted to receive data from identification cards of the first type 17. However, the wireless communication means 5 is in one embodiment also adapted to transmit data to identification cards of the first type 17.
It is to be noted that in general, the invention is not limited to the use of identification cards. Any identification unit 17 suitable for secure communication with a tachograph, and comprising processing means able to transmit user identification data may be utilised within the scope of the invention. Examples of identification units are mobile phones, PDAs or similar portable devices. However, for the sake of example, user identification units will be exemplified by identification cards in the following. Identification devices 11 suitable for any of the above examples may be installed in the tachograph 1 instead of the card reader 11. Any advantages presented below may however be implemented in general identification units.
Hereto, an identification card of the first type will be described in more detail below. Hereinafter, identification cards of the first type 17 will be referred to as a card device 17.
The card reading means 11 comprises a card receiving slot 15 (see Fig. 3) into which an identification card such as a driver's license may be inserted. A card inserted into the card receiving slot 15 hence physically interfaces with card reading means 11. By inserting a card, the card reading means 11 can read the content of the inserted card and provide the read data to the processing means 9. Thereby, the tachograph 1 can get access to e.g. the identity of the driver so that the logging of driving data in the tachograph 1 can be associated with the correct driver. The card reading means 11 can also receive data from the memory 7 and provide the received data to the card in the card receiving slot 15. Thereby, the card, which typically comprises electronics such as a processor and a memory, can store data from the tachograph 1. The data can for instance relate to personal driving data regarding the vehicle associated with and recorded by the tachograph 1. Driving data is herein defined as data logged by the tachograph 1 regarding e.g. driving speed of a driver. Hence, a card of this type can exchange data, i.e. transmit data to and receive data from the tachograph 1.
Cards, such as standard driver cards comprising smart card chips which can only communicate with a tachograph via card reading means 11 will in the following be referred to as identification cards of a second type 19.
Cards having two communication interfaces, i.e. for use with both the wireless communication means 5 and the card reading means 11 will hereinafter be referred to as a card device 17.
In view of the above, in some embodiments the tachograph 1 hence provides means for use with identification cards of the first type 17 by wireless communication with the wireless communication means 5, and for communication with identification cards of the first type 17 and second type 19 by physically interfacing with card reading means 11.
Alternatively, a tachograph may be provided that comprises the wireless interface, i.e. the wireless communication means 5, the memory 7 and processing means 9 but not card reading means 11. Such a tachograph is hence for use with card devices 17 but not with identification cards of the second type 19.
With reference to Fig. 2a, a card device 17 is shown. The card device 17 is for use with a tachograph comprising wireless communication means such as the tachograph 1 described above. The card device 17 comprises inter alia first processing means 17-1, a first memory 17-2 operatively connected to the first processing means 17-1, and wireless communication means 17-3 of the card device 17. The wireless communication means 17-3 of the card device 17 is operatively connected to the first processing means 17-1. The wireless communication means 17-3 of the card device 17 can transmit data received from the first processing means 17-1 to the tachograph 1. The wireless communication means 17-3 of the card device comprises an antenna for implementing the wireless communication with the tachograph 1.
Further, the first processing means 17-1 may be adapted to modulate data signals to be transmitted from the card device 17. The first processing means 17-1 may also be adapted to demodulate data signals in variations of the card device 17 in which the card device 17 is adapted to transmit and receive data. In one embodiment, the first processing means 17-1, the first memory 17-2 and the wireless communication means 17-3 of the card device 17 are comprised in a Radio Frequency Identification Device chip circuit 21 (abbreviated RFID). The RFID chips circuit 21 may be of active or passive type. An active type RFID chip circuit 21 comprises e.g. a rechargeable capacitor for supplying power to electronic components thereof. A passive RFID chip circuit 21 may comprise an inductive coil for interaction with an electromagnetic field to supply power to electronic components of the RFID chip circuit 21.
In one alternative embodiment, the first processing means 17-1, the first memory 17-2 and the wireless communication means 17-3 of the card device 17 are comprised in a wireless Universal Serial Bus device (abbreviated USB).
Coding means 8 of the tachograph 1 shown in Fig. 1 is adapted to provide encrypted communication between the memory 7 and the first and second memories 17-2 and 19-2 of the card device 17.
Advantageously, the card device 17 comprises means which allows a user to communicate with the card device 17 by physical interaction therewith. To this end, the card device 17 may in one embodiment comprise a display 25 and a keypad 27 to which the first processing means 17-1 is operatively connected. In particular, this may provide improved user interaction with the card device 17 in that a user may directly input data into the card device 17 by physically interacting with said card device 17. The display and the keypad 27 can be located on a planar outer surface 29 of the card device 17, as illustrated in Fig. 2a. Alternatively, the keypad 27 and the display 25 may be integrated into a touch screen configuration on the planar outer surface 29.
The first processing means 17-1 used in the card device 17 may be any type of suitable processor, e.g. a Central Processing Unit (abbreviated CPU), a micro processor or the like.
Since no physical interaction is needed with the tachograph 1 in order for the card device 17 to communicate with the tachograph 1, the card device 17 experiences less wear compared to cards subject to regular insertion into a tachograph. Hence, by means of the card device 17, an identification card having a longer life time may be provided.
The memory 17-2 may be adapted to store software updates of the tachograph 1. Typically, a software update of a tachograph comprises rigorous security routines in order to comply with current security requirements. By storing a software update in the memory 17-2 and including a cryptographic key therewith, a simple software update of the tachograph 1 may be achieved via the identification card of the first type 1. A correct cryptographic key enables the process of updating the software in the tachograph 1. Further, the tachograph 1 may also record at what time, and by whom the update was performed.
The card device 17 may further comprise power supplying means 31, as shown in Fig. 2b. The power supplying means 31 can for instance comprise an inductive power supply coil, e.g. a transformer. Alternatively, power supply means 31 can comprise a resonant power supply coil. Said powering techniques are known to the skilled person to implement and its implementation will therefore not be elaborated further herein. The power supply means 31 may in one embodiment provide direct powering of the card device 17. Direct powering may be achieved by connecting the card device 17 to a power source, wherein a user may provide user input to the card device 17 by means of e.g. keypad 27 or a touch screen. The power supply means 31 may alternatively charge a rechargeable battery (not shown) in the card device 17. This may be particularly preferable in embodiments in which the card device 17 comprises a display such as display 25 and/or input means such as keypad 27. Thereby more freedom is provided to a user, who may input data also when the card device 17 is situated at a location where no external power source is available.
As shown in Fig. 2c, the card device 17 can also comprise second processing means 19-1, a second memory 19-2 operatively connected to the second processing means 19-1, and interface means 19-3 operatively connected to the second processing means 19-1. For simplicity, illustrations of the display 25, the keypad 27 and the power supply means 31 shown in Fig. 2a have been left out of Fig. 2b.
Said electronic components 19-1, 19-2 and 19-3 are typically of the type used in e.g. standard smart cards for e.g. driver cards and hence components that are typically comprised in identification cards of the second type 19. Hereto, the second processing means 19-1, the second memory 19-2 and interface means 19-3 can be comprised in a smart card chip 23. Typically, the interface means 19-3 is adapted to receive from and transmit data to the tachograph 1 when the card device 17 is physically connected to the tachograph 1 by insertion of the card device 17 into the card receiving slot 15.
The second memory 19-2 is normally for use to store data from the tachograph 1 relating to driving data of the vehicle. This may be advantageous in that the second memory 19-2 is typically not a memory that a user can access and modify data in.
A typical embodiment of the card device 17 comprises the components 17-1, 17-2, and 17-3 and components 19-1, 19-2 and 19-3. Further, a user interface is generally provided by means of the display 25 and keypad 27. As mentioned above, the user interface may of course also be comprised of a touch sensitive screen instead of the keypad 25. A variation of the card device 17 having both a keypad 25 and a touch sensitive screen is however also envisaged.
Beneficially, the card device 17 provides communication with the tachograph 1 even when a user of the card device 17 is located at a distance from the tachograph 1. The user will still be able to provide data input into the card device 17 to the tachograph 1. Hence, the card device 17 may function as an extended user interface of the tachograph 1. The card device 17 may thus function as a remote controller of the tachograph 1 in addition to the usual functionality of a driver's identification card that logs tachograph data on the smart card chip 23 portion of the card device 17. Typically, the remote controlling of the tachograph 1 relates to control of features and functions related to the tachograph profile of the user associated with the card device 17.
Additionally, the wireless communication means 17-3 of the card device 17 may provide higher data transfer speed than the current data transfer speed provided by a smart card. Examples of transfer protocols that can be utilized are wireless USB, Wireless Local Area Network (abbreviated WLAN) and Bluetooth.
Examples of data that can be transmitted from the card device 17 can for instance relate to route information and personal settings for the user profile associated with the card device 17. Additionally, the card device 17 may also be used as a master controller of the vehicle associated with the tachograph 1. Hereto, the freight forwarder company may via a card device 17 wirelessly transmit data to one or more tachographs, which data may relate to e.g. a geographic area in which the vehicle may be allowed to move. Thereby, the freight forward company may in a simple way provide vehicle specific data to a tachograph. As an example, an application may be to allow a plurality of vehicles to move within a construction area, and where movement of vehicles outside said area is undesired. The tachograph 1 may have means to indicate to a driver of a vehicle in which the tachograph 1 is installed when the driver exceeds the outer limits of such an area. Such means may include a Light Emitting Diode (abbreviated LED) that starts to flash, or sound generating means. In one embodiment, a tachograph is envisaged that may control the vehicle by sending a control signal e.g. to the brakes of the vehicle if the vehicle moves outside the geographic boundary defined by the data provided by the card device 17. Of course, further variations and applications are possible within the scope of the claims, as would be apparent to the skilled person.
Fig. 3 shows a perspective view of the card receiving slot 15 of the tachograph 1 in Fig. 1.
The card device 17 typically is thicker than ordinary smart cards on the market to house the additional electronics needed e.g. for wireless communication. Therefore, in one embodiment, the card receiving slot 15 of tachograph 1 comprises mechanical means 33 that allows adjusting the width of the card receiving slot 15. The width of the card receiving slot 15 is to be construed as a dimension in a transverse direction with respect to a longitudinal direction of an opening 35 of the card receiving slot 15. When the card receiving slot 15 has a first card slot dimension, a wall w of the card receiving slot 15 is at a position P1. The first card slot dimension allows the card receiving slot 15 to receive smart cards that are available at the market today, having approximately the thickness of e.g. a credit card.
The card receiving slot 15 can be adjusted to have a second card slot dimension, by displacing the wall w in a direction transverse to a plane defined by the wall w, to a position P2. The second card slot dimension allows the card receiving slot 15 to receive the card device 17. The second card slot dimension is greater than the dimension of the first card slot dimension. Hence a thicker card device 17 may be received by the card receiving means 11. The card device 17 may be up to about 3 mm thick.
The mechanical means 33 can for instance be implemented by springs that automatically adjust to the thickness of a card when introduced in the card receiving slot 15. When using a spring, the card receiving slot 15 will have its first card receiving dimension in an idle state.
Further, the card receiving slot 15 is in operative connection with power supply means 37 of the card reading means 11 in order to power a card device 17 inserted into the card receiving slot 15. In one embodiment, the power supply means 37 of the tachograph 1 is arranged such that it may provide power to the power supply means 31 of the card device 17 by utilizing an electromagnetic field. Wireless power supply may hence be utilized by e.g. inductive or resonant energy transfer. To implement inductive power supply in the card device 17, an inductive coil (not shown) may be utilized.
In one alternative embodiment, the power supply means 37 of the tachograph 1 is arranged such that an inserted card device 17 will physically interface with the power supply means 31 of the card device 17 to power the card device 17.
The tachograph 1 will typically know what type of card is used therewith without manual input concerning this matter from the user. Since the mechanical means 33 will be in their idle state when an identification card of the second type 19 is inserted, the processing means 9 will know that the inserted card is of the second type 19. On the other hand, should the mechanical means expand the card receiving slot 15 to its second card slot dimension, the processing means 9 will know that the inserted card is of the first type 17.
Additional functions of the card device 17 may for instance comprise communication between the first and the second memories 17-2 and 19-2, as illustrated in Fig. 5. Normally, it is not desired that a user write data to the second memory 19-2, because the second memory 19-2 usually comprises data received from the tachograph 1 relating to driving routines logged by the tachograph 1 and transmitted to the second memory 19-2 by the tachograph 1. Such data is not to be modified by e.g. a driver. Therefore, direct communication between the second memory 17-2 and the first memory 19-2 is usually not desired. Hereto, in one embodiment of the card device 17, communication between the first memory 17-2 and the second memory 19-2 is provided through the tachograph 1. Hence if a user wants access to data in the second memory 19-2 in order to view e.g. their driving data logged by the tachograph 1 in a remote location from the tachograph 1, a request R1 to receive that data will first be sent to the tachograph 1. The tachograph 1 will then send a request R2 to the second processing means 19-1. The second processing means 19-1 can then provide the requested data to the tachograph 1 in step D2. The data can then be sent to the card device 17 in step D2 from the tachograph 1. The user may then access the requested data, and he may be free to modify the data.
By utilizing the tachograph 1, better control of data provided to the first memory 17-2 may be achieved. The tachograph 1 may for instance in one embodiment log info about any data requested from the second memory 19-2 by the card device 17.
Communication between the first and the second memory 17-2 and 19-2 can be provided when the card device 17 is physically connected to the tachograph 1 via the card reading means 11.
Additionally, in one embodiment the first and the second memory 17-2 and 19-2 respectively may communicate via the wireless communication means 5 which may be operatively connected also to the second memory 17-2 of the card device 17.
Data that may be saved to the second memory 19-2 may for instance relate to user profile related data such as user settings and driver data that has been corrected by the driver. Data of the latter type will however not overwrite the original driver data. The process of saving data to the second data memory 19-2 would use similar steps as described above.
The tachograph 1 will be permitted to write data such as driving log data to the second memory 19-2 in all variations.
Examples of applications of the card device 17 include but are not limited to driver's and co-driver's identification cards for commercial vehicles and to supervisors of drivers for super user purposes of a plurality of vehicles associated with e.g. a freight forwarder company.
The person skilled in the art will realise that the present inventive concept by no means is limited to the embodiments described above. On the contrary, many variations and modifications are possible within the scope of the appended claims. For instance, the coding means 8 of the tachograph 1 and the processing means 10 may be housed in the same electronic circuit. Further, the memory 7 can be comprised in processing means 9. Alternatively, the memory 7 may have a secure portion which is housed in processing means 9 and a non-secure portion that is not housed in processing means 9.
Moreover, the tachograph 1 may not need to be physically interfacing with a vehicle via the vehicle interface 13 utilizing CAN-bus connection. Instead, the tachograph 1 may in a variation thereof comprise a Global Positioning System (abbreviated GPS) to wirelessly measure vehicle related data, e.g. the speed of the vehicle. Advantageously, a driver using the tachograph 1 would not have to enter data regarding driver activities between a previous and a current insertion of the identification card if for instance the vehicle has been travelling on a ferry. The GPS would recognise that the vehicle has travelled on water. Therefore, no driver input would be needed in this case explaining driver activities during the ferry transport. As an alternative to GPS communication, it would also be possible to utilize other Global Navigation Satellite Systems (abbreviated GNSS) such as for instance the Galileo positioning system.
Further examples within the scope of the appended claim include a tachograph in which both the wireless communication means 5 and the communication means 11 provide wireless communication with identification units 17. The transfer protocol utilised by the two wireless communication means 5 and 11 may the same. Alternatively, each wireless communication means 5, 11 may utilise different transfer protocols.
To simplify the interaction between a user and the tachograph 1, the tachograph memory 7 may in one embodiment be adapted to store a plurality of user profiles, each being associated with at least one user. When a user has been identified by means of an identification unit 17, the user will get access to the user profile. The user profile may contain preferred user settings and the like, which upon access are loaded from the memory 7.
