Abstract
An onboard device includes: a communication unit configured to communicate with an onboard device included in an onboard network; a detection unit configured to detect a new onboard device that is an onboard device newly added to the onboard network; and a sleep processing unit configured to, in a detected state where the new onboard device has been detected by the detection unit, transmit a sleep request for transitioning to a sleep state in synchronization with an onboard device included in the onboard network, to the new onboard device via the communication unit.
Claims4
An onboard relay device comprising:
- a communication unit configured to communicate with an onboard device included in an onboard network;
- a detection unit configured to detect a new onboard device that is an onboard device newly added to the onboard network;
- a sleep processing unit configured to transmit to the new onboard device via the communication unit a sleep request for transitioning to a sleep state in synchronization with an onboard device included in the onboard network, when the new onboard device has been detected by the detection unit,
- wherein a sleep function information is stored in a storage unit being provided outside the onboard relay device, and
- the sleep processing unit is configured to determine whether or not the communication unit has received a sleep response from the new onboard device that corresponds to the transmitted sleep request and updates a sleep information of the new onboard device with the stored sleep function information when the sleep information of the new onboard device does not correspond with the stored sleep information.
A sleep control method for an onboard device that is capable of communicating with another onboard device included in an onboard network, the sleep control method comprising the steps of:
- detecting a new onboard device that is an onboard device newly added to the onboard network;
- in a detected state where the new onboard device has been detected, transmitting a sleep request for transitioning to a sleep state in synchronization with an onboard device included in the onboard network, to the new onboard device,
- wherein the sleep function information is stored in a storage unit being provided outside the onboard relay device,
- the sleep control method further comprises the step of:
- determining whether or not the communication unit has received a sleep response from the new onboard device that corresponds to the transmitted sleep request transmitted and updating a sleep information of the new onboard device with a stored sleep function information when the sleep information of the new onboard device does not correspond with the stored sleep information.
