Abstract: A vehicle control device has a portable-unit restraining control unit which, when the portable unit is inserted in the slot in the drive-permitted state, irremovably fixed the portable unit, which is inserted in the slot, by the portable-unit restraining unit and, when the portable unit is inserted in the slot in the drive-prohibited state, releases the portable unit from the locking effected by the portable-unit restraining unit to allow removal of the portable unit from the slot.

Abstract: A vehicle door outer handle system includes: an operating handle formed from a handle main body and a cover covering the outer side of the handle main body; a pair of electrodes; and a circuit board on which a detection circuit is provided for detecting a change in capacitance between the electrodes; the electrodes and the circuit board being housed within the operating handle. The electrodes are patterned on the circuit board, and a ground pattern connected to the detection circuit is formed so as to be disposed at a position offset from the electrodes if viewed through the circuit board.

Abstract: A vehicular remote control system includes, on a portable device side, a portable device side first receiver, a portable device side transmitter, and a portable device side second receiver and, on a vehicle side, a vehicle side first transmitter, a vehicle side second transmitter, and a vehicle side receiver. Transmitting and receiving a request signal requesting an identification signal, the identification signal, an interrogation signal, and a response signal between the portable device and the vehicle allows a door lock actuator to be operated if the portable device is legitimate. When the vehicle side second transmitter or the portable device side second receiver breaks down, transmission and reception of a second request signal and the interrogation signal is carried out using the vehicle side first transmitter and the portable device side first receiver, thereby making the door lock actuator operate unhindered without the need for providing special alternative means.

Abstract: A request signal transmitted from LF antennas of a vehicle-mounted unit is received by a radio terminal through an LF antenna. In response to the request signal, the radio terminal transmits a response signal from an antenna. The response signal is received by an RF unit of the vehicle-mounted unit. The vehicular remote control device controls an operating state of a vehicle-mounted device depending on the judgment of a match between the response signal and identification information inherent in the vehicle. The radio terminal has a light-emitting diode. When the radio terminal receives a failure diagnosis signal that is transmitted instead of the request signal, the radio terminal does not transmit a response signal, but energizes the light-emitting diode.

Abstract: When a door sensor is touched, a vehicle-mounted unit and a portable unit performs mutual communications for authentication, and the doors are unlocked. When the door sensor is touched without intending to unlock the doors, wasteful consumption of electric energy is avoided which would otherwise result from mutual communications for authentication triggered by a request signal. When the door sensor may possibly be operated not for the purpose of unlocking the doors, e.g., when a CPU detects the doors as being already unlocked from a signal outputted from a door lock knob switch, a request signal is inhibited from being transmitted from the vehicle-mounted unit to the portable unit.

Abstract: In a vehicular remote locking/unlocking system, when a locking or unlocking switch outputs a trigger signal, a second transmission device transmits identification information transmission disable signal, before a first transmission device transmits identification information request signal. When a portable device of the vehicular remote system receives the transmission disable signal, even if the portable device receives a subsequent request signal, transmission of identification information from the portable device is disabled for a predetermined period of time, thereby disabling operation of a door lock actuator. Since the second transmission device transmits a transmission disable signal a plurality of times in succession, the influence of noise is eliminated, thereby reliably preventing the portable transceiver within the vehicle from outputting an ID signal.

Abstract: An apparatus automatically locks the doors of a vehicle based on mutual communications between a portable unit and a vehicle-side control unit. After the doors are closed and locked after all the passengers get off the vehicle, the user of a portable unit unlocks the doors in order to allow a person without the portable unit to fetch something left in the vehicle. After the person opens a door, takes whatever he or she needs, and closes the door, the doors are automatically locked. When a door sensor is operated to unlock the doors, and one of the doors is opened, a memory means stores information indicating that the portable unit is present in a predetermined range outside of the vehicle. If the memory means stores information that the doors are unlocked, then the doors are automatically locked.

Abstract: A vehicle outer handle system includes a handle main body formed from a synthetic resin and having a hollow grip part, and an electrode for detecting a change in capacitance. One end of the handle main body is swingably supported in a door outer panel, and the electrode is housed within the grip part. A grounded electrostatic shield plate is disposed with the grip part outwardly of the electrode, thereby preventing an erroneous determination of a user's intention of opening the door.

Abstract: A vehicle equipment remote control system includes an electronic control unit that controls the transmission from vehicle exterior transmitters and a vehicle interior transmitter such that, when one of switchover intention detection means detects a vehicle user's intention to switch over a door between a locked state and an unlocked state, among the vehicle exterior transmitters, the vehicle exterior transmitter on the side where the switchover intention detection means that has detected the switchover intention is located transmits a request signal requesting reply data, and a prohibition signal is transmitted from at least one of the remaining vehicle exterior transmitter and the vehicle interior transmitter to prohibit the transmission of reply data from the portable transceiver, the prohibition signal being at a low output level that cannot be received by the portable transceiver that is present on the side where the switchover intention detection means that has detected the switchover intention is l
