Abstract
Official abstract text for this publication.
An onboard vehicle communication system includes a first ECU configured to manage charge information of a vehicle, a gateway connected to the first ECU, a second ECU connected to the gateway, an onboard vehicle communication device configured to communicate with the outside of the vehicle, and a local bus that connects the first ECU and the onboard vehicle communication device. The first ECU is configured to transmit charge information of the vehicle to the onboard vehicle communication device via the local bus when an external charge device is charging a vehicle.
First claim
Opening claim text (preview).
1 . An onboard vehicle communication system comprising: a first ECU configured to manage charge information of a vehicle; a gateway connected to the first ECU via a first global bus; a second ECU connected to the gateway via a second global bus, which is a communication bus that differs from the first global bus; an onboard vehicle communication device configured to communicate with the outside of the vehicle; and a local bus, which is a communication bus that is not connected to the gateway, wherein the local bus connects the first ECU and the onboard vehicle communication device, wherein the first ECU is configured to transmit charge information of the vehicle to the onboard vehicle communication device via the local bus when an external charge device is charging the vehicle. 2 . The onboard vehicle communication system according to claim 1 , wherein the onboard vehicle communication device includes a controller and a communication transceiver configured to communicate a communication message via the local bus, and the controller and the communication transceiver are connected by a signal line that permits transmission of a communication message from the communication transceiver to the controller and not connected by a signal line that permits transmission of a communication message from the controller to the communication transceiver. 3 . The onboard vehicle communication system according to claim 1 , wherein the onboard vehicle communication device includes a controller and a communication transceiver configured to communicate a communication message via the local bus, and the controller and the communication transceiver are connected by a signal line so that direct transmission of a communication message from the communication transceiver to the controller is permitted and direct transmission of a communication message from the controller to the communication transceiver is restricted. 4 . The onboard vehicle communication system according to claim 2 , wherein the communication transceiver is a first communication transceiver, the onboard vehicle communication device is connected to the gateway via a third global bus, which is a communication bus that differs from the first global bus and the second global bus, the onboard vehicle communication device further includes a second communication transceiver configured to communicate a communication message via the third global bus under control of the controller, and the second communication transceiver and the controller are connected by a signal line that permits transmission of a communication message from the second communication transceiver to the controller and connected by a signal line that permits transmission of a communication message from the controller to the second communication transceiver. 5 . The onboard vehicle communication system according to claim 1 , wherein the onboard vehicle communication device is connected to the gateway via a third global bus, which is a communication bus that differs from the first global bus and the second global bus, and the onboard vehicle communication device is configured to communicate with each of the first ECU and the second ECU.
