Abstract
In a communication method of an Ethernet network for a vehicle, a load of a CPU in a reception ECU is reduced by enabling the reception ECU receiving an Ethernet message to receive the message with a changed period. For this, each time a message is transmitted from a transmission ECU to an Ethernet switch, the message is transmitted with a changed period by the Ethernet switch selectively only to a reception ECU determined on the basis of setting information and information included in the transmitted message, thereby controlling a message reception period for each reception ECU.
Claims11
A communication method of an Ethernet network for a vehicle, the communication method comprising:
- setting, in an Ethernet switch, setting information for controlling a message reception period for each Ethernet electronic control unit (ECU);
- periodically transmitting, from a transmission ECU among the Ethernet ECUs connected to the Ethernet switch, a message to the Ethernet switch;
- determining, on the basis of the setting information and information included in the message, a reception ECU to which the message is transmitted, among the Ethernet ECUs connected to the Ethernet switch;
- and
- operating, by the Ethernet switch, to transmit the message transmitted from the transmission ECU, to the determined reception ECU,
- wherein each time the message is transmitted from the transmission ECU to the Ethernet switch, the message is transmitted by the Ethernet switch selectively only to the reception ECU determined on the basis of the setting information and the information included in the transmitted message, thereby controlling the message reception period for each reception ECU.
