Embodiment Construction

[0038] figure 1 Two exemplary implementations of the method according to the invention are shown in a number of successive cycles. The activities of transmitting device 10 and transmission device 11 are shown here in three superimposed time levels. Also shown is a receiving device 12 , to which information is transmitted from the transmitting device.

[0039] Although reference numbers are not indicated for all information 21 , 22 for a better overview, all information comprises three components 100 , 101 (or 101 ′) and 102 (or 102 ′) respectively, ie information content 100 , information Counter 102 (or 102') and checksum 101 (or 101'). In this figure, the corresponding information content 100 is symbolized by a capital letter and the information counters are each shown as two digits. Different capital letters here symbolize that the corresponding content is or was current at different times. The two digits yield an exemplary continuous message count according to the pres...

Abstract

The invention relates to a method for providing a message content (100) for being received by a transmission device (11) and a method for receiving, by means of a transmission device (11), a message (21, 22) of an interface region (14) between a sending apparatus (10) and the transmission device. In the former method, at least two different message counters are determined and at least two messages with the message content and one of the message counters in an interface area between the sending apparatus and the transmission device are provided. According to the second method, a message counter (102, 102') of a message to be transmitted message is determined and the affiliated message from the interface area, which further comprises at least one another message including another message counter, is taken.

Description

technical field [0001] The invention relates to a method for providing and transmitting information. Background technique [0002] In modern vehicles a plurality of control units are used which communicate intensively with one another. In addition to standard communication via the so-called Controller Area Network (CAN), FlexRay networks are increasingly being used to exchange information quickly and securely. [0003] A FlexRay network is a timed bus capable of transmitting messages (information) between a first and a second control device. The information can be sent on an event basis (for example as a function of rotational speed) or at predetermined time intervals (for example every 10 ms). [0004] In addition to the actual information content, it is also important for the receiving control unit to know, especially in the case of safety-critical data, whether the sending control unit is still functioning correctly and sending the current data and whether the transmiss...
