Definitions

  • the invention relates to an electronic tachograph, in particular an electronic tachograph with digital data storage, and a method for storing entries in such a tachograph.
  • Tachographs are control devices that are installed to monitor various vehicle operating parameters in motor vehicles.
  • the monitored vehicle operating parameters are usually detected by a variety of types of sensors and stored by the tachograph and further processed.
  • Vehicle operating parameters may be, for example, travel times, a distance covered or average and maximum speeds traveled during the distance traveled. Certain events, such as driving time interruptions, can also be detected and stored by the tachograph. The recorded and stored data can then be read out.
  • Electronic tachographs can in addition to the basic functions, such as recording and recording the Travel distance and travel time, often perform additional functions, such as calculating driving and rest periods.
  • some tachographs can also support smartphone applications and provide corresponding data to mobile devices.
  • Electronic tachographs also enable a modern and simple way of driver authentication.
  • Each driver receives a driver card, d. H. a chip card on which his personal data is stored. This card is inserted in the tachograph before the start of the journey, which then assigns the following journeys exactly to the owner of the driver card.
  • the tachograph stores the determined data in an internal memory from which the data can later be downloaded.
  • some tachographs now also offer the ability to make various user-specific settings as soon as the current user has been identified by their personal smart card. User-specific data are read out from the chip card for this purpose to make the settings. However, downloading and making settings may take some time so that delays may occur before the driver can start his journey.
  • the object of the invention is to provide an improved tachograph in which personal settings can be made as quickly as possible.
  • a method of storing entries in a tachograph includes receiving a command to store an entry in a storage unit of the tachograph, the entry including current date information and data, and wherein the entry Entry can be uniquely assigned to a user.
  • the method further comprises checking a currently available storage capacity of the storage unit, wherein the storage unit can store a maximum number of entries. If the maximum number of possible entries in the storage unit has not yet been reached, the new entry is stored in the storage unit without overwriting entries already stored.
  • the date information of the stored entries is checked and the entry is overwritten with the new entry having the oldest date information, wherein one or more users can be defined as the main user in the tachograph, and only those stored entries can be overwritten which are not assigned to a main user.
  • Attitudes of main users who use a vehicle particularly often remain even if the user is, for example, on vacation or sick, and the vehicle is driven by one or more other drivers during this time.
  • the stored data is available faster than data which must first be retrieved from the driver's driver card. Settings can therefore be made faster before departure. For a primary user who predominantly uses a particular vehicle, it is very convenient for certain data and information to be readily available.
  • the data contained in an entry may include at least one of a personal identification number of the associated user, an identification number uniquely associated with a personal driver card of the user, and information about user-specific settings.
  • an entry can be clearly assigned to the user. Are in the entry If this user's preferred settings are saved, the user does not have to make the settings each time they start their journey. The settings do not have to be read from his driver card. Rather, the desired settings are quickly and easily available and can be made as soon as the driver has been detected and an entry assigned to the driver has been found.
  • the information about user-specific settings can in particular have user-preferred settings for one or more functions of the tachograph.
  • Tachographs have more and more functions. Making the settings for each of the functions before each ride takes a long time. For drivers who use the same vehicle very often, therefore, it is tedious to make the settings anew before each ride. Re-entering the settings for one or more main users is therefore no longer necessary.
  • a tachograph has a storage unit.
  • the tachograph is adapted to store entries in the storage unit, wherein an entry contains current date information and data, and wherein the entry can be uniquely assigned to a user.
  • the tachograph is designed to check a currently available storage capacity of the storage unit before storing an entry, wherein the storage unit can store a maximum number of entries. If the maximum number of possible entries in the memory unit has not yet been reached, the tachograph is designed to store the new entry in the memory unit without overwriting entries already stored.
  • the tachograph is adapted to check the date information of the stored entries and to overwrite the entry with the new entry having the oldest date information, the tachograph being further adapted , one or more users as the primary user and overwrite only those stored entries that are not associated with a primary user.
  • Each entry may include a personal identification number of the assigned driver and the tachograph may further be configured to deposit a personal identification number of a user defined as the main user and to compare the personal identification numbers stored in the entries with the stored identification numbers to check whether a stored one Entry is assigned to a main user.
  • the tachograph may be further configured to delete one or more of the deposited main users if each of the entries stored in the storage unit is associated with a primary user and no entry can be deleted.
  • the tachograph may be further configured to overwrite the entry with the oldest date information, irrespective of being associated with a primary user, if each of the entries stored in the storage unit is associated with a primary user.
  • a vehicle in particular a motor vehicle, may have such a tachograph.
  • FIG. 1 shows an arrangement with a tachograph 1 and an external device 2.
  • the external device 2 may for example be a card reader, which is adapted to read a driver card. Every driver of a company usually has a driver card.
  • a driver card is a (chip) card, on which data are stored, which are assigned to the respective driver. For example, a personal certificate of the driver may be stored on the driver card. If the driver inserts his driver card in the external device 2, or brings his driver card in the vicinity of the external device 2, so that a wireless connection between the driver card and the external device 2 can be established, the external device 2, for example, reads the personal first Certificate of the driver to identify it.
  • a card reader may for example be integrated in the tachograph 1, or may be formed as an external unit, which can be connected by means of a wireless or wired connection with the tachograph 1.
  • the external device 2 can also be, for example, a portable electronic device, such as a mobile phone, smartphone, tablet, Blackberry, laptop, or the like.
  • the external device 2 may be a smartphone of the driver.
  • an application (app) or a program can be stored on the smartphone. Data and information of the driver can then be stored, for example, on the external device 2, so that the external device 2 replaces the driver card and an additional driver card is not required. If the external device 2 brought in the vicinity of the tachograph 1, a connection to the tachograph 1 can be established.
  • a connection between the tachograph 1 and the external device 2 may be any type of wireless or wired connection.
  • a radio link between the external device 2 and the tachograph 1 can be established.
  • the external device 2 may also be connected to the tachograph 1 by any suitable wired interface.
  • the tachograph 1 can read the personal certificate of the driver and the driver to be authenticated. On the external device 2 or on the driver card can also be stored information on the past rides of the driver. This information can also be read by the tachograph 1. Furthermore, personal settings of the driver with respect to the tachograph 1 can be stored in the external device 2 or on the driver card. These can also be read by the tachograph 1. For example, the driver's personal settings may relate to preferred language settings or other settings related to the tachograph 1. If the driver was recognized by the tachograph 1 on the basis of the personal certificate, the driver can, for example, personally be welcomed, z. Example by means of a corresponding display on a display, and the corresponding user-specific settings can be made by the tachograph 1.
  • the reading of the data and setting information from the tachograph card or the external device 2 may take some time. Therefore, often, various data and information are cached in the tachograph 1 for later use.
  • the tachograph 1 may for example have a memory unit 12 for this purpose.
  • the storage unit 12 has a certain storage capacity, so that a certain number N of entries in the storage unit 12 can be stored. For each entry, for example, current date information can be stored. This means that it is still comprehensible at a later date when the entry was saved (eg date and time).
  • each entry can be assigned to a specific driver. This can be done, for example, by storing a unique driver identification number for each entry. However, it is also possible, for example, to store a driver card number for each entry.
  • each driver card is uniquely associated with a particular user, if the card has been uniquely identified by its number, the corresponding assigned driver can also be determined.
  • Each entry may still have a certain amount of data.
  • the data may relate to the settings desired by the user. This is exemplary in FIG. 2 shown.
  • FIG. 2 shows a list view of various entries. Since the memory space in the tachograph 1 is usually limited, only a certain number N of entries can be stored. For example, the last N entries can be stored at any time. For each entry is in the list in FIG. 2 in each case the corresponding date specified. In addition, a card number (CardNumber) is stored for each entry. The card certificate (Card-CHR) to the respective driver card can also be stored in the entry. Furthermore, each entry contains additional data, such as settings for certain functions (FeatureX, FeatureY) or settings for a Multi Purpose Data Recorder (not shown).
  • FeatureX FeatureX
  • FeatureY Multi Purpose Data Recorder
  • the tachograph 1 When the tachograph 1 is used for the first time, or when the memory of the memory unit 12 has been emptied for some reason, first the existing N places are filled for entries. If the list or the memory is full and a new entry is to be created, the oldest entry at that time is overwritten. That is, when a new entry is to be stored, first the available storage space in the storage unit 12 can be checked. If there is no free memory space, the date information of the stored entries can be checked and the oldest entry can be overwritten with the new entry.
  • the tachograph 1 can, for example, first be identified in FIG search the entries stored in the memory unit 12 for data and information before reading out data and information from the external device 2 or the driver card.
  • the driver or card number can be compared with the stored entries. If a corresponding entry is found, the stored data can be read from the memory unit 12 and the corresponding settings made. Since this information is already present in the tachograph 1 (in the memory unit 12), the time until all settings have been made and the driver can start his journey is shortened. If there is no corresponding entry in the memory unit 12, the data must be read from the driver card or the external device 2 so that the registration process takes some time.
  • Motor vehicles such as trucks or buses are often driven by different, changing drivers. Most of the time a vehicle is usually assigned to one or a few main users. However, if a driver or is this on vacation, the vehicle is usually driven by one or more other drivers during this time, to avoid too long periods of vehicle life. It may happen that during prolonged absence of a main driver whose last entries in the memory unit 12 in the tachograph 1 were overwritten until its return with the entries of other (temporary) driver.
  • long waiting times may occur until the driver can start his journey if the corresponding data first have to be read from the external device 2 or the driver card.
  • main users for a tachograph 1 can be defined.
  • only one main user for a vehicle can be defined, or several main users for one and the same vehicle can be defined.
  • a driver may define himself as the main user of a vehicle as soon as his driver card or external device 2 has been identified.
  • main users can only be defined by authorized users.
  • main users can only be defined by an administrator.
  • the vehicles of a company are also located at regular intervals, for example for maintenance, in a central office or in a workshop. There can be over any wireless or wired interface to the tachograph 1 and then one or more main users are defined.
  • a user is defined as the main user
  • the entries of these users as exemplified in FIG. 3 displayed, no longer overwritten. For example, an entry was saved for a primary user at a particular time. While this entry in the procedure according to FIG. 2 would be overwritten at a later date, remains the entry of a main user in the procedure according to FIG. 3 receive. If an entry is identified as belonging to a main user, it is thus virtually permanently stored in the tachograph 1 and can not be overwritten again. In the example in FIG. 3 such entries are marked with an arrow.
  • FIG. 4 shows an example of a method for storing entries in a tachograph 1.
  • a command for storing a new entry in the memory unit 12 of the tachograph 1 are received (step 401).
  • the new entry may contain current date information and data as shown above.
  • the new entry can be uniquely assigned to a user.
  • the available storage capacity of the storage unit 12 may be checked (step 402).
  • the memory unit 12 can store a maximum number N of entries.
  • the new entry can be stored in the storage unit 12 without overwriting previously stored entries (step 403).
  • the date information of the stored entries can next be checked (step 404).
  • the entry with the oldest date information may then be overwritten with the new entry (step 405).
  • one or more users are defined as main users in the tachograph 1, only those stored entries are checked or overwritten which are not assigned to a main user.
  • Defining a user as the primary user can be done via any suitable interface, e.g. As human-machine interface (HMI, Human Machine Interface), CAN (Controller Area Network), diagnostic interface, remote HMI, etc.
  • HMI Human-machine interface
  • CAN Controller Area Network
  • diagnostic interface remote HMI, etc.
  • a user as the main user for example, a personal identification number of the driver or his card is deposited and accordingly characterized. If an entry is identified as the oldest entry in the storage unit 12, the identification number stored for the entry can be compared with the stored identification numbers. If the identification number corresponds to a stored identification number, the corresponding entry is not overwritten and the next entry in the list is checked.
