Abstract:
1. A method for preventing message loss in a controller area network (CAN) system, said CAN system including a plurality of distributed nodes capable of communicating with each other through a CAN bus, each of the plurality of distributed nodes being allocated a task, where the plurality of distributed nodes include at least one node of a first type and at least one node of a second type, said method comprising: determining a synchronization frequency; sending synchronization frames from the node of the first type to the node of the second type, wherein the synchronization frames are sent at the synchronization frequency; and performing a task activation synchronization on the node of the second type based on information included in the synchronization frames, where the task activation synchronization includes modifying a local task period of the node of the second type.
