METHOD AND APPARATUS MONITORING ACTIVATION OF SUBORDINATE LIN NETWORK BLOCKS BY ANALYSING ACTIVATION REASONS Russian patent published in 2014 - IPC G06F13/42 G08C25/02 B60W10/30 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to monitoring activation of subordinate blocks of LIN networks. The device (D) is designed to monitor activation of subordinate blocks (OE1-OE5) of a multiplexed LIN communication network (R) controlled by a driving block (OM). The device (D) is designed such that when the driving block (OM) detects activity in the network (R) during a standby phase, i) it instructs the driving block (OM) to transmit to at least some subordinate blocks (OE1-OE5) and preferably to all blocks, which can be a source of an activation request, request messages to which they must respond via a response message containing a status field, the value of which characterises a local or non-local source of the detected activity, ii) analyse the value of the status field of each response message received by the driving block (OM) in order to determine if at least one subordinate block is a source of activity and if so, whether said activity is justified with respect to the corresponding value of the status field, and iii) allow the driving block (OM) to acknowledge activation of subordinate blocks only if the activity is justified.

EFFECT: preventing activation of subordinate blocks of a LIN network if the source of an activation request is interference.
