Procedure for checking the behavior of bus participants on a CAN FD bus in accordance with specifications

摘要

The invention relates to a method for checking the specification-compliant behavior of transmitters and receivers on a CAN FD bus in the event of a fault. The object of the invention is to propose a test method which ensures simple and reliable checking of a bit rate switchover according to the CAN FD standard According to the invention, the object is achieved by a method for checking the specification-compliant behavior of bus participants on a CAN FD bus with the following steps: integrating a function generator and a measuring device into the CAN FD bus of a network, consisting of a CAN FD -Controller and a bus device to be tested, which are in communication, - Generating a test signal (3) on the function generator, containing a first message (1) and a second message (2), the first message (1) being a specification-specific message and the second message (2) is a faulty message, - recording and checking a sign The course of an error message (E) (error frame) of the bus subscriber to be tested following the test signal (3).
