    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 tire pressure monitoring system used for a vehicle includes a sensor unit, a receiving device, and a control device. The sensor unit is provided at each wheel of the vehicle, detects tire pressure of the each wheel with a tire pressure sensor and transmits data of the detected tire pressure by radio waves. The receiving device includes a receiving antenna that is provided at an outside of the vehicle to receive the data of the tire pressure transmitted from the sensor unit. The control device includes a data acquisition unit that acquires the data of the tire pressure received by the receiving device.

    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.

    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 vehicle control system includes a vehicle-mounted device and a mobile device portable by a user. The vehicle-mounted device permits a predetermined operation on a vehicle based on a response signal transmitted from the mobile device in response to a request signal from the vehicle-mounted device. The vehicle-mounted device includes a first communication device performing a wireless communication with the mobile device under a predetermined communication protocol different from that of the request signal. The mobile device includes: a second communication device performing the wireless communication with the first communication device; and a response control unit that responds to the request signal under a condition that the mobile device is located in a communication range of the first communication device and the wireless communication between the first communication device and the second communication device is established.
