Definitions

  • the invention relates to a method for transmitting data via a Ubertragungsweg between at least one arranged in a vehicle tachograph and a distance from the vehicle data processing system and a corresponding system for transmitting data over such Ubertragungsweg.
  • Motor vehicles especially commercial vehicles, are often equipped with a tachograph or tachograph to u. a. record the driving and rest periods of both the commercial vehicle and the driver or passenger involved.
  • this data and other data stored and recorded in the tachograph must be noted and archived in accordance with legal regulations in a defined time window.
  • the tachographs In order to update the digital tachograph in particular, the tachographs have been brought for maintenance in a workshop with appropriate equipment, so that the motor vehicles or commercial vehicles are not ready for use at this time. In most cases, the trip recorder is removed or specific data is played directly from the service center m the tachograph via a standardized interface.
  • a disadvantage of this method is that due to the maintenance of the tachograph within the workshop, the vehicles in which the tachographs are arranged are not ready for use, which leads to an inefficiency in the utilization of the vehicles.
  • the object of the invention is to provide a method and a system of the type mentioned, which allow easier maintenance of a tachograph during operation.
  • a tachograph arranged in a vehicle and a data processing system spaced from the vehicle are used, the data being transmitted wirelessly from the data processing system to the tachograph at least over a partial section of the transmission path.
  • the tachograph is assigned a GSM module and / or a module for wireless data transmission and is connected to it.
  • the module for wireless data transmission for example, an IEEE-801.x standard, a
  • the tachograph can have one of the above two modules, two modules or even more than two modules.
  • a connection for wireless data transmission is established between the GSM module and / or the wireless data transmission module and the data processing system. Because the connection takes place wirelessly, a data exchange between the tachograph and the data processing system assigned to the GSM module and / or the module for wireless data transmission can also take place over a large distance. This means in particular that the Schreiber does not have to be in the immediate vicinity of a maintenance center, but also over long distances from the data processing system - for example, the operating carrier - can communicate remotely with the data processing system.
  • the tachograph After establishing a connection, the tachograph is instructed by the data processing system to receive specific data.
  • Specific data here means that the data processing system transmits selected information to the tachograph depending on, for example, the position or model type of the tachograph or the level of experience of the driver or passenger. Thus, it is not exclusively data that must be exchanged between the tachograph and the data processing system due to a pre-selected transmission protocol. Rather, the data processing system uses additional information to transmit the data that is suitable and needed for this tachograph.
  • the authentication of the data processing system to the at least one tachograph and / or the at least one tachograph at the data processing system ensures that only one tachograph associated with the data processing system can receive information or specific data from the data processing system. This is particularly important because due to the Fernkommunikationsmogzieren between the at least one tachograph and the data processing system, the wirelessly transmitted data can be intercepted by a variety of receivers, manipulated and abused.
  • the Authentication preferably with a secure connection, provides a remedy.
  • the specific data is transmitted from the data processing system to the at least one tachograph.
  • the specific Since ⁇ th are stored in the tachograph.
  • the data can also be read out from the data processing system to the tachograph at a later time, and not just at the time of data transmission.
  • Voice output device are issued. In this way, information communicated to the driver or the passenger by the data processing system can be made available, which information is immediately communicated to the driver via the tachograph. It is also possible that due to the
  • Caching the specific data at a later time by the driver or passenger can be retrieved.
  • the information contains telematic information.
  • telematic information can be collected. These may include, for example, roadways, construction sites, route changes and traffic jam warnings.
  • This information can be transmitted via the data processing system to the at least one tachograph.
  • the tachograph thereby becomes part of a minimal traffic telematics solution, whereby it is particularly preferred if the at least one tachograph has a device for self-localization such as a GPS module or a receiver for toll infrared waves or is connected to this.
  • a further particularly advantageous variant of the method is characterized in that the specific data comprise an update of a data processing program of the drive ⁇ writer.
  • the specific data comprise an update of a data processing program of the drive ⁇ writer.
  • software updates or firmware updates of the tachograph can be made remotely.
  • parts of the updated data processing program or the entire updated data processing program can be received by the tachograph, stored and then installed, the installation can be carried out both automatically and manually by the operator of the tachograph.
  • An updating to be carried out by a workshop can hereby be dispensed with, which reduces the maintenance times of the vehicle.
  • a plurality of tachographs is present and the data processing system communicates with the tachographs independently.
  • the data processing system a variety of information on a variety of tachograph models and the various tachograph associated vehicles is maintained. Due to the ability to communicate independently with the individual tachographs, the specific data may be adapted to the particular tachograph, the particular vehicle and the driver currently driving the vehicle. This is a great relief in particular in the monitoring of a larger number of vehicles or commercial vehicles, which occurs for example in freight forwarders.

In this way, transmission errors are better compensated.
