TESTING APPARATUS AND METHOD FOR CHECKING A BEHAVIOUR OF A NETWORK COMPLEX COMPRISING CONTROLLERS OF A MOTOR VEHICLE IN THE EVENT OF ERRONEOUS AND/OR MANIPULATED NETWORK DATA TRAFFIC

摘要

The invention relates to a method for checking a behaviour of a network complex (12) comprising controllers (13) of a motor vehicle (10) in the event of erroneous and/or manipulated network data traffic (27), wherein a respective communication model (22) is stipulated for all controllers (38), a network model (24) stipulates a data network (14) of the motor vehicle (10), the network complex (12) is simulated by connecting the communication models (22) to the network model (24), and a model testing device (30) operates the communication models (22). The invention provides for at least one noise source model (29) to be connected to the network model (24) and operated by the model testing device (30) and for it to be identified whether at least one of the communication models (22) and/or the network model (24) adopts a predetermined fault state (32).
