Definitions

  • the invention particularly relates to a method for introducing data, in particular a sequence control, into at least a first and a second control unit of a motor vehicle, according to the preamble of claim 1.

  • the tester Prior to the start of the programming software of booth 1 is installed on all control units of this vehicle electrical system.
  • the tester transmits the software of the overall package 2 which is suitable for a control unit A to the control unit A. If the control unit A subsequently reboots - all other control units in the electrical system have not yet been provided with new software at this point in time - the control unit A already the newly installed software. This leads to errors because of the inconsistent software state, software version 2 on control unit A, software version 1 on control unit B (security aspect).
  • the object of the invention is, in particular, to specify a method with which the control units of a motor vehicle can be accelerated with updated data or updated sequential control systems.
  • the core idea of the invention is to improve the known method for introducing data, in particular a sequence control, into at least a first and a second control unit of a motor vehicle by the following steps.
  • the first and the second control device are each provided with a sequence control which has a deactivatable deactivation state, a programming mode and an operating mode with operating functions.
  • the first and the second control unit are each put into the deactivation state, in which the execution of operating functions of the operating mode, preferably at least largely, are prevented.
  • Each of the first and second controllers is placed in the programming mode during which the suspendable deactivation state of each controller continues to exist.
  • the deactivation state of all control devices is canceled after the respective data or sequential control has been introduced in the programming mode in all control units.
  • each of the in-vehicle controllers that transmit data over a data bus in their mode of operation is brought into a cancelable disable state prior to the introduction of data or scheduling.
  • a control unit located in the deactivation state preferably outputs no or only a few data via the data bus, so that in the deactivation state the entire bandwidth of the data bus is available for the introduction of data and sequential control systems into the control units.
  • the communication between the control units of the vehicle preferably resumes only when all programming measures have been completed on the control units to be programmed and the deactivation state of each control unit, ie newly programmed and possibly non-reprogrammed control units are shared and the control units return to their operating mode. This avoids the erroneous entry of fault memory entries in the control units, as would be the case if the control units returned to operating mode immediately after their respective programming and the control units communicated with each other via the data bus with (not yet) coordinated sequential control systems.
  • a control unit located in the deactivation state remains in the deactivation state after a restart of the control unit, for example an unintentional restart due to a power failure.
  • a restart of the control unit for example an unintentional restart due to a power failure.
  • the first and the second control device in the programming mode each provided with new data or with a completely or partially new flow control. These are stored in particular in a flash E-PROM of the relevant control unit.

  • the first and the second control unit in a vehicle workshop by a diagnostic device, in particular a controller tester, preferably after an authorization test, in the reversible deactivation state, the programming mode or the operating mode is set.
  • the invention also proposes a motor vehicle with a vehicle electrical system which has at least one first and one second control unit, wherein data or sequence controls are introduced into the first and the second control unit by the method according to the invention.

  • the respective control unit After its restart, the respective control unit checks - possibly after further tests - whether the cancelable deactivation state or special mode is set. If so, the parameters continue to remain in accordance with the settings previously made by the tester in order to have optimal conditions for the measures at the control unit. This means that the controller, as long as the tester does not switch it again, easily remains in its deactivation state or in its special mode and does not interfere with the programming of other onboard network subscribers.
  • the tester continues with the programming of further control units, as described above.
  • the tester cancels the deactivation state or special mode, i. the flash mode previously set to "ON” is set to "OFF".
  • the relevant control units are transferred from the special mode to the operating mode.
  • the controllers then re-execute their operational functions - using possibly updated data and / or on the basis of a possibly updated sequential control.
  • control units and thus also the transmission medium used for the programming remain in the optimum state for the programming until the completion of the programming of all control devices, eg the maximum bandwidth available via CAN bus is not reduced by application messages. This reduces the risk of programming aborts and also the overall programming time.
  • the control units no longer erroneously switch over to runflat operation, since it is now made clear, via the special mode according to the invention, that the communication lapses because of the programming. This prevents damage that can occur when emergency functions are triggered in the "dry state", eg a scratched disc by a wiper function on a dry windshield, a blown mirror heating, etc.
  • the control units try only at a reasonable time to record the communication to the other on-board network participants. This eliminates errors due to an overall programming process that has not yet been completed, which reduces the cost of error analysis and resolution.

Abstract

L'invention concerne un procédé de programmation de données dans au moins un premier et un deuxième modules de commande d'un véhicule automobile. Selon l'invention, pour que les modules de commande puissent être dotés plus rapidement de données actualisées ou de commandes d'exécution actualisées, le premier et un deuxième modules de commande sont respectivement munis d'une commande d'exécution qui présente un état de désactivation annulable, un mode de programmation et un mode de service avec des fonctions de service. Le premier et le deuxième modules de commande sont respectivement mis en état de désactivation, dans lequel l'exécution des fonctions de service du mode de service est inhibée, de préférence au moins à quelques détails près. Le premier et le deuxième modules de commande sont respectivement amenés dans le mode de programmation, pendant lequel l'état de désactivation annulable de chaque module de commande est maintenu et l'état de désactivation de tous les modules de commande est annulé après avoir introduit les données respectives dans tous les modules de commande en mode de programmation.
