Abstract
In a vehicle-mounted device, a first time period measuring unit starts measurement of a first time period when detecting an exit movement of a user. Before an elapse of the first time period, a vehicle side transmission unit periodically transmits a response request signal at a predetermined transmission period; and a locking and unlocking control unit keeps a door unlocked while receiving a response signal, locks the door when incapable of receiving the response signal, and keeps the door unlocked when capable of receiving the response signal at the elapse of the first time period. After the first time period is elapsed, the vehicle side transmission unit periodically transmits the response request signal at a second time period; and the locking and unlocking control unit keeps the door unlocked while receiving the response signal, and locks the door when incapable of receiving the response signal.
