Abstract:
The present disclosure relates to a method of monitoring Controller Area Network (CAN) nodes and a monitoring device performing the method.
In an aspect a method of a monitoring device of monitoring a plurality of CAN buses is provided, wherein at least one CAN node is connected to each CAN bus, said plurality of CAN buses being interconnected via the monitoring device. The method comprises detecting, for each CAN bus, any dominant data being sent over said each CAN bus by a CAN node connected to said each CAN bus and routing said any dominant data received by the monitoring device over said each CAN bus to all remaining CAN buses without overwriting any dominant data sent over the remaining CAN buses.
