Definitions

  • the invention relates to a method for transmitting messages between bus users with the features of the preamble of patent claim 1.
  • control units are, for example, an electronic engine control and the control of an automatic transmission.
  • a diagnostic bus is used to transmit control signals and the other line is provided as a status line. This results in a considerable constructive effort for the diagnosis alone.
  • a method of the type mentioned at the outset is known from DE 19837242 C, in which data transmission also takes place via a separate diagnostic bus in the event of a fault.
  • the diagnostic bus represents a redundant data bus.
  • DE 39 34 974 A1 there is considerable construction effort.
  • a possibly occurring error in the data transmission is generally not recognizable, since the diagnostic bus then automatically “jumps in.” If, as in DE 39 34 974 A1, the status of the transmitted message is checked, this does not change in the event of an error.
  • the diagnostic device can be used to specifically cause the bus subscriber normally receiving the message to output the message on the communication bus. If he does not do this or if the message is damaged, there is a fault. However, it is not yet possible to determine where the fault is.
  • a third bus subscriber who is not involved in this message transmission in normal operation can be made to record this message in diagnostic operation.
  • the status of this message for the three bus participants is then read out. If there is an error in the transmitter, the two received bus participants have the same status ("no message available"). If the error is in the receiver, the two receivers have different statuses.
  • the method according to the invention is particularly suitable for bilateral message transmission. For messages that are transmitted in normal operation between more than two bus users, it is no longer necessary to involve another bus user in the operating mode that is different from normal operation. Here it is sufficient if the status of this message is read out for all bus participants involved in this message transmission. A sender error does not change the recipient's message status. An error in a receiver can be recognized in the different status of this receiver compared to the other receivers.
  • the figure shows the typical architecture of a data bus system in the vehicle.
  • the status of a switch 1, which is connected to a control unit 2 is to be communicated to a further control unit 4 with the aid of the data bus.
  • the control devices 2 and 3 and a further control device 4 are connected to a communication bus 6, as is a gateway 5.
  • Each control device 2, 3, 4 can be addressed via the gateway 5 via a diagnostic tester 8.
  • the switch 1 is read in by the control unit 2 and the switch status information is transmitted to the control unit 3 via the bus system.
  • the status of the switch can be queried by the control unit 2 by the tester 8.
  • the status of the message transmitted via the bus 6 can be queried by the control unit 3.
  • control unit 2 In the event of a fault, the status of switch 1 is correctly recognized in control unit 2, but not in control unit 3. It is therefore not possible to determine whether the control unit 2 does not put the message about the state of the switch 1 on the bus or whether the control unit 3 is not receiving the message correctly.
  • a diagnostic device (tester 8) is connected via the gateway 5 and a diagnostic mode is set.
  • the control unit 3 is specifically asked for the message from the control unit 2. Once it has received it and it is working properly, it places this message on the communication bus. The tester receives the message and determines that the overall system is working properly.
  • the recipient or recipients can be prompted to output the message of interest in each case. In this way, the entire system can be checked in a targeted manner.
  • control unit 4 is prompted to also receive the switch status message.
  • the message states of control units 2 to 4 are queried via the gateway. If the states of control units 3 and 4 are the same, the error is in control unit 2; if they are different (i.e. control unit 4 and not control unit 3 has received the message), the error is in control unit 3.
  • tester 6 which shows which signals are received by which control units. If all control devices to be addressed do not receive a message, the error is in the transmitter, otherwise in the receiver, which in contrast to the other receivers does not receive a message.

Abstract

L'invention concerne un procédé de transmission de messages entre plusieurs stations respectivement reliées à un bus de communication pour échanger des messages ainsi qu'à un dispositif de diagnostic conçu pour diagnostiquer un dérangement du bus de communication. La station recevant le message est sollicitée par l'intermédiaire du dispositif de diagnostic de sortir le message sur le bus de communication, en mode opératoire de diagnostic de transmission de messages entre deux stations, lequel est différent du mode opératoire en fonctionnement normal.
