Definitions

  • the present invention concerns a tachograph arrangement, and a method for a tachograph arrangement according to the preambles for the independent claims.
  • a tachograph is a device that, by law, must be present in heavy goods vehicles and buses that are involved in commercial traffic (there are exceptions), which device continuously records the velocity and driving and rest times. There are two ways to record the information; the older way uses a paper diagram (analog tachograph), but since 2005 a computer memory in the tachograph has been used together with a driver card in the form of a smart card to store the information (digital tachograph).
  • the justification for the tachograph requirement is the ability to monitor driving and rest times. It also makes it possible to monitor the velocity. Goods vehicles can drive at a maximum of 80 km/h (90 km/h on expressways and motorways), buses 90 km/h. Goods vehicles with trailers can drive at only 80 km/h, and this applies to expressways and motorways as well.
  • a driver can drive a maximum of 4 hours and 30 minutes without a break. Then a break of at least 45 minute must be taken.
  • Tachographs have been manipulated, e.g. by means of trickery with diagrams or the installation of devices that cause the tachograph to think that the goods vehicle is standing still when it is being driven. This has led to the introduction of digital tachographs with personal driver cards. This type of tachograph reads the vehicle velocity via an encrypted electrical interface, and also stores this information in encrypted form. Each driver can own only one driver card, and the driver must insert this card into the tachograph so that all his activities can be recorded.
  • the latest generation of digital tachographs is also able to automatically and wireiessly transfer data both from the internal memory of the tachograph and from the memory in the driver card to a server, where data can be stored and analyzed in the desired manner.
  • This wireless transfer often occurs by means of a telematics unit in the vehicle that has a built-in GSM/GPRS modem.
  • the tachograph is generally connected to the telematics unit via an electrical interface, such as a CAN data bus.
  • US-20 0/273478 concerns a control unit that can be used to automate the downloading of data from a tachograph. This can be performed when the vehicle is being driven, and it will also prevent the driver from neglecting to archive data. It is possible to both archive and evaluate data based on the automated download.
  • US-2011/137517 concerns a method wherein driving data for a vehicle are downloaded from the tachograph automatically.
  • the downloaded driving data a evaluated automatically and compared against rules to determine whether the driving data are in violation of any rule.
  • WO-201 1/043715 describes a method and system for establishing a connection between a vehicle and a database, wherein the connection is to be used to transfer tachograph-related information.
  • a tachograph records tachographic data when a driver card is inserted into its card reader.
  • US-8421590 describes a system and method in which the driver of a vehicle manually enters his status (driving or resting) by means of buttons. The status and the identity of the driver are sent wirelessiy to a remote unit that analyzes the information and determines whether the driver is in compliance with the legal requirements. The result can then be forwarded, or sent back to the vehicle.
  • US-2010/292890 provides that data (such as sensor data, distance driven, engine operating time, current vehicle position) stored in electronic control units of a vehicle can be sent to an external unit in order to ensure that the driver is getting sufficient rest time.
  • data such as sensor data, distance driven, engine operating time, current vehicle position
  • EP-2482162A1 describes a system in which vehicle- related data are sent wireiessly from a vehicle to a server, where the data are analyzed before being sent back to the vehicle. The primary purpose is to find errors in the vehicle.
  • the data stored by the tachograph must be downloaded from the tachograph to a server in accordance with predetermined rules, which results in increased administrative work and costs for the hauling contractors.
  • the object of the present invention is to achieve an improved solution for tachographs in terms of managing tachograph information and, in particular, in connection with hardware and software updates.
  • the object is to ensure higher quality and improved management at a lower cost.
  • the data package is compiled in a communication unit in the vehicle, wherein the data package contents include unprocessed sensor data and tachograph card information, along with a time stamp. These data packages are then sent along, preferably encrypted, and preferably automatically without involving the driver. The data packages are transferred via a
  • the tachograph information can then be read out from the tachograph module by means of various logins, depending on the authorization that the user (hauling contractor, driver, police are examples of authorizations) possesses.
  • the present invention exhibits the following advantages, among others: 1.
  • the vehicles avoid having to drive around with expensive electronics for calculating and saving driving and rest times in an environment that is harsh from an electronics standpoint
  • the hauling contractor avoids having to periodically download and save data stored in the tachograph, as all the data are already saved on a server.
  • Figure 1 is a block diagram that schematically illustrates the present invention.
  • Figure 2 is a flow diagram that shows the method according to the present invention.
  • FIG. 1 shows a schematic block diagram of a tachograph arrangement 2, which is indicated in the figure by a dotted periphery.
  • the tachograph arrangement 2 comprises a communication unit 4 disposed in a vehicle 8 (such as a goods vehicle or a bus), a card reader 8 adapted so as to receive a tachograph card 10, read out tachograph information from the tachograph card and transmit a tachograph card information signal 12 containing tachograph card information.
  • the tachograph card is preferably a so-called smart card that is of the type described above and is used to store information about, for example, the driver and about driving and rest times.
  • the present invention is applicable to all types of tachograph cards, such as driver cards, repair shop cards, control cards to which the police have access, and company cards.
  • the tachograph arrangement 2 further comprises a tachograph module 14 that is disposed externally in the vehicle and adapted so as to determine tachograph information 24 according to a predetermined set of rules.
  • the tachograph module 14 is, for example, implemented in a data server that is located in a defined and secure computer environment, for example, under the control of a supervising authority.
  • the communication unit 4 is adapted so as to receive the tachograph card information signal 2 from the card reader 8 and one or a plurality of sensor signals 16 containing unprocessed sensor data from one or a plurality of sensors 18 in the vehicle.
  • the sensors 18 comprise, for example, a sensor adapted so as to measure and determine sensor data that contain a value representing pulse information related to the rotation of a rotating part of the vehicle, such as the engine or the gearbox.
