Abstract: An on-vehicle apparatus control system includes: a first on-vehicle switch and a second located farther from an on-vehicle reception unit than the first on-vehicle switch; an on-vehicle control device; and a portable machine. In a case where the on-vehicle switches is operated, the on-vehicle control device transmits a response request signal to the portable machine, the portable machine returns a response signal, and the on-vehicle control device controls an on-vehicle apparatus. The on-vehicle apparatus control system further includes a level switch. In a case where the first on-vehicle switch is operated, the level switch switches transmission intensity of a portable machine transmission unit or reception sensitivity of an on-vehicle reception unit to a first level, and in a case where the second on-vehicle switch is operated, the level switch switches the transmission intensity or the reception sensitivity to a second level higher than the first level.

Abstract: An on-vehicle control device mounted on a vehicle includes: an on-vehicle transmission unit that transmits a response request signal to a portable machine carried by a user; and an on-vehicle reception unit that receives a response signal transmitted from the portable machine in response to reception of the response request signal, and a remote control signal transmitted from the portable machine in response to an operation on an operation switch disposed in the portable machine. The on-vehicle reception unit performs: reception processing on the remote control signal on a basis of a first reception sensitivity when receiving the remote control signal transmitted from the portable machine; and reception processing on the response signal on a basis of a second reception sensitivity lower than the first reception sensitivity when receiving the response signal transmitted from the portable machine.

Abstract: The driver seat unit and the other-seat unit are connected by the single signal line. A direction of a current passed through a motor is switched using contacts of a window opening switch and a window closing switch in the other-seat unit. When a window closing manipulation is performed by the driver seat unit, the current is passed through a coil of a relay via the contacts of the window closing switch, and a contact of the relay is switched to pass a forward current through the motor. When a window opening manipulation is performed by the driver seat unit, the current is passed through a coil of a relay via the contacts of the window opening switch, and a contact of the relay is switched to pass a reverse current through the motor.
