Abstract: A position determination system determines a position of a mobile terminal relative to a vehicle by a wireless communication. The position determination system includes: a communication device disposed in a vehicle compartment and configured to receive a wireless signal transmitted from the mobile terminal and detect a reception strength of the received wireless signal. The position determination system is configured to: determine whether the mobile terminal is existing in the vehicle compartment; estimate an amount of absorbers that exists in the vehicle compartment and may absorb radio waves having a frequency used for the wireless communication; adjust an inside determination value which is used as a threshold for determining that the mobile terminal is existing in the vehicle compartment; and determine that the mobile terminal is existing in the vehicle compartment in response to the inside device strength being equal to or greater than the inside determination value.

Abstract: A key-shape data management system includes a storage server, an acceptance server, and a transmission server. The storage server stores vehicle identification information capable of identifying a vehicle, mechanical lock identification information capable of identifying a mechanical lock mounted on the vehicle, key-shape data of a mechanical key used in combination with the mechanical lock, and information on multiple manufacturing bases capable of manufacturing the mechanical key. The acceptance server accepts a request for acquiring the mechanical key together with determining information and delivery location information indicating a delivery location of the mechanical key. The transmission server determines the vehicle identification information based on the determining information, determines the key-shape data based on the vehicle identification information, determines one of the manufacturing bases corresponding to the delivery location, and transmits the delivery location information and the key-shape data to the determined manufacturing base.

Abstract: A reception strength detection unit is connected to reception antennas located in a vehicle compartment and detects a reception strength of a radio wave from a mobile terminal for each of the reception antennas. A reception determination unit is connected to an auxiliary antenna located at a predetermined position that is a blind spot of the reception antenna and determines whether the radio waves has been received by the auxiliary antenna. When the radio wave has not been received by the auxiliary antenna, an existence position calculation unit calculates an existence position of the mobile terminal based on the reception strength detected by the multiple reception antennas. When the radio wave is received by the auxiliary antenna, the existence position determination unit determines the predetermined position at which the auxiliary antenna receiving the radio wave is located as the existence position of the mobile terminal.

Abstract: An occupant detection apparatus includes a first detection unit, a second detection unit, and an occupant presence determination unit. The first detection unit detects an occupant present in a first region or a second region, among the plurality of regions. The second detection unit detects an occupant present in the second region or a third region, among the plurality of regions. The occupant presence determination unit determines whether an occupant is present in each of the first region, the second region and the third region, based on a first detection result obtained by the first detection unit and a second detection result obtained by the second detection unit.

Abstract: A mobile device includes a receiver receiving a radio wave from a wireless communication device, a transmitter transmitting an authentication signal when the radio wave that is received requests transmission of the authentication signal, a vibration detector detecting whether there is vibration, and an operation controller bringing the mobile device into a communication enabled state where the receiver and the transmitter are in operation when the vibration is detected, and bringing the mobile device into a communication disabled state where at least one of the receiver and the transmitter is stopped when the vibration is not detected. When the radio wave is received in the communication enabled state, the operation controller brings the mobile device into a communication enabled continuous state where the receiver and the transmitter are in operation even if the vibration is no longer detected.
