Electronic control device, control system, control method, and non-transitory computer readable medium

A control method executed by a computer of an electronic control device, the electronic control device including at least one transceiver configured to perform a communication with a communication equipment, the control method comprising:

• operating in a first mode to execute processing related to the communication during the transceiver performing the communication;
• transitioning from the first mode to a second mode in response to a stoppage of the communication during the computer operating in the first mode;
• transitioning from the second mode to a third mode in response to a predetermined period having passed without the communication in the second mode;
• stopping at least a part of the processing related to the communication in the third mode;
• and
• transitioning from the second mode to the first mode in response to an occurrence of the communication during the computer operating in the second mode except when the communication is a reception of a wake-up request that requests the computer to transition to the first mode.

A non-transitory computer readable medium storing a computer program configured to be executed by a computer of an electronic control device, the electronic control device including a transceiver configured to perform a communication with a communication equipment, the computer program comprising instructions configured to, when executed by the computer, cause the computer to carry out:

• operating in a first mode to execute processing related to the communication during the transceiver performing the communication;
• transitioning from the first mode to a second mode in response to a stoppage of the communication during the processor operating in the first mode;
• transitioning from the second mode to a third mode in response to a predetermined period having passed without the communication in the second mode;
• stopping at least a part of the processing related to the communication in the third mode;
• transitioning from the second mode to the first mode in response to an occurrence of the communication during the controller operating in the second mode except when the communication is a reception of a wake-up request that requests the computer to transition to the first mode.

An electronic control device for a vehicle comprising:

• at least one transceiver configured to perform a communication with a communication equipment;
• at least one processor;
• and
• at least one memory storing instructions that, when executed by the at least one processor, cause the at least one processor to carry out at least:
• transitioning to a network mode from a sleep mode in response to receiving a wake-up request;
• operating in the network mode to execute processing related to the communication;
• transitioning from the network mode to a prepare bus-sleep mode in response to a stoppage of the communication in the network mode;
• transitioning from the prepare bus-sleep mode to a bus-sleep mode upon determining that a predetermined period has passed without the communication in the prepare bus-sleep mode;
• stopping, in the prepare bus-sleep mode, a part of the processing executed in the network mode;
• and
• transitioning from the prepare bus-sleep mode to the network mode in response to an occurrence of the communication in the prepare bus-sleep mode except when the communication is a reception of the wake-up request.
