Vehicle door locking and unlocking vehicle-mounted device, vehicle including vehicle-mounted device, and vehicle door locking and unlocking system including vehicle-mounted device

A vehicle door locking and unlocking vehicle-mounted device comprising:

• communication means for receiving a lock command or an unlock command from a user terminal directly or through a server;
• and
• at least two internal relays connected to wiring installed in a vehicle between a door key switch installed in the vehicle and a door lock actuator installed in the vehicle, wherein
• the internal relays include a first internal relay and a second internal relay connected in parallel to ground or a power supply, the first internal relay and the second internal relay independently connected to at least one external relay to respectively control locking and unlocking of a door installed in the vehicle,
• the external relay includes a first external relay and a second external relay,
• the door lock actuator is powered through two power feed lines,
• the two power feed lines are connected with a door lock relay unit respectively through first external relay and a second external relay, and at least part of wiring at a portion bypassed by the first external relay and the second external relay is cut off,
• when the lock command is received, a state of the first internal relay changes for the first predetermined time, so that power supply voltage is applied from the first external relay to one of the power feed lines to drive the door lock actuator in a first direction to lock the door, and
• when the unlock command is received, a state of the second internal relay changes for the second predetermined time, so that power supply voltage is applied from the second external relay to the other of the power feed lines to drive the door lock actuator in a second direction to unlock the door,
• the communication means receives an engine starting relay control command to switch between a starting-disabled state and a starting-enabled state of the vehicle from the server,
• the vehicle-mounted device further comprises:
• engine starting relay input/output means for controlling an engine starting external relay configured to switch between the starting-disabled state and the starting-enabled state of the vehicle;
• and
• vehicle information-associated control means for controlling the engine starting external relay based on the engine starting relay control command.
