Transceiving method and system for vehicle controllers
View Patent ↗Systems and methods for controlling vehicle controllers are provided. According to an exemplary embodiment, a method of transceiving performed in a network is provided. The methods comprises transmitting, by a first controller, a first network management (NM) message, wherein the first NM message comprises a request for a subscription to a specific partial network cluster (PNC) to one or more second controllers, performing, by each of the one or more second controllers, an operation setting for the specific PNC in response to the first NM message, broadcasting, by the first controller, a second NM message, wherein the second NM message comprises a request that an identifier of the specific PNC be set to the network, and, maintaining, by the one or more second controllers, a wake-up state, regardless of a preset sleep condition, upon receiving the second NM message.
1 . A method of transceiving performed in a network, the method comprising:
transmitting, by a first controller, a first network management (NM) message, wherein the first NM message comprises a request for a subscription to a specific partial network cluster (PNC) to one or more second controllers;
performing, by each of the one or more second controllers, an operation setting for the specific PNC in response to the first NM message;
broadcasting, by the first controller, a second NM message, wherein the second NM message comprises a request that an identifier of the specific PNC be set to the network; and
maintaining, by the one or more second controllers, a wake-up state, regardless of a preset sleep condition, upon receiving the second NM message.
2 . The method of claim 1 , further comprising transmitting, by the first controller, a third NM message,
wherein the third NM message comprises a request for a cancellation of the subscription to the specific PNC to each of the one or more second controllers.
3 . The method of claim 2 , wherein:
the first and third NM messages comprise a network request reason field, and
the network request reason field comprises an NM identifier (NM ID) for each of the one or more second controllers.
4 . The method of claim 2 , wherein:
the first NM message, the second NM message, and the third NM message comprise a control bit vector field, and
the control bit vector field comprises:
an indicator for a request for a PNC subscription; and
an indicator for a request for a cancellation of a PNC subscription.
5 . The method of claim 2 , wherein:
the first NM Message, the second NM message, and the third NM message comprise a partial network information (PNI) field, and
the PNI field comprises information about an operation of the one or more second controllers.
6 . The method of claim 1 , wherein:
the second NM message comprises a network request reason field, and
the network request reason field comprises a value of “0”.
7 . The method of claim 1 , wherein the network is a vehicle network.
8 . A network system comprising:
a first controller configured to:
transmit a first network management (NM) message comprise a request for a subscription to a partial network cluster (PNC) to one or more second controllers; and
broadcast a second NM message comprising a request that an identifier of the specific PNC be set to a network; and
the one or more second controllers configured to maintain a wake-up state, regardless of a preset sleep condition, upon receiving the second NM message from the first controller.
9 . The system of claim 8 , wherein;
the first controller is configured to transmit a third NM message, and
the third NM message comprises a request for a cancellation of the specific PNC to each of the one or more second controllers.
10 . The system of claim 9 , wherein:
the first NM message and the third NM message comprise a network request reason field, and
the network request reason field comprises an NM identifier (NM ID) for each of the one or more second controllers.
11 . The system of claim 9 , wherein:
the first NM message, the second NM message, and the third NM message comprise a control bit vector field, and
the control bit vector field comprises:
an identifier for the request for the subscription to the specific PNC; and
an identifier for the request for the cancellation of the specific PNC.
12 . The system of claim 9 , wherein:
the first NM message, the second NM message, and the third NM message comprise a partial network information (PNI) field, and
the PNI field comprises information about an operation of the one or more second controllers.
13 . The system of claim 8 , wherein:
the second NM message comprises a network request reason field, and
the network request reason field comprises a value of “0”.
14 . The system of claim 8 , wherein the network is a vehicle network.
