Vehicle remote control system

A vehicle-mounted device comprising a processor, wherein the processor is configured to:

• receive, from a server, a relay control command to make a switch between a starter-disabled state and a starter-enabled state of a vehicle;
• control an external relay configured to make a switch between the starter-disabled state and the starter-enabled state of the vehicle based on the relay control command without affecting a running state of a vehicle engine;
• employ the relay control command to switch to the starter-disabled state, in response to determining that the running state of the engine is off and that the elapsed time since turning off of the running state of the vehicle engine is equal to or longer than a relay change-prohibited period,
• wait for a vehicle power reevaluation period, in response to employing the relay control command to switch to the starter-disabled state, and
• control the external relay to switch to the starter-enabled state, in response to determining that the running state of the vehicle engine is on after the vehicle power reevaluation period has elapsed;
• and
• control the external relay in a stand-alone manner to switch from a starter-disabled state and a starter-enabled state without being based on the relay control command, in response to communication with the server failing to be established.
