In a switching control device of a vehicle control device, when a vehicle is in a non-traveling condition, an operating method for a pressing operation, which is carried out with respect to a push switch in relation to a switching control for switching an operating state of a drive source of the vehicle or a power supply state to a vehicle mounted device of the vehicle, in a case that the operating state of the drive source of the vehicle or the power supply state to the vehicle mounted device of the vehicle is switched from off to on, differs from an operating method for a pressing operation in a case that the operating state or the power supply state is switched from on to off.

Vehicle control device

A lock control device of a vehicle includes: a door lock device that causes a door of the vehicle to be in an unlocked state or a locked state; a door handle that is operated in order to allow the door to become an open state from a closed state; a sensor array that is provided in the vicinity of the door handle and that is arranged with a plurality of contact detection sensors; and a main controller that controls the door lock device to be in the unlocked state when the plurality of contact detection sensors sequentially detect the contact in a first direction which is a direction from the sensor array toward the door handle.

Lock control device for vehicle

Upon determination that a mobile device is present within a first communication area, a control device maintains transmitter power output of an electromagnetic wave to be transmitted from a communication section. Further, the mobile device decreases sensitivity for receiving the electromagnetic wave such that the first communication area is narrowed to a second communication area. Then, the control device determines, based on presence/absence of a response from the mobile device, whether the mobile device is present within the second communication area.

Smart entry system

A frequency control apparatus includes: an input operation unit which detects a presence/absence of an input of a predetermined operation by an operator; and a control unit which, when the input of the predetermined operation by the input operation unit is detected, calculates radio frequencies, each of the radio frequencies being where a minimum value of differences with respect to multiplied frequencies of a current drive frequency of a device is less than or equal to a predetermined value, and which changes the current drive frequency of the device so that minimum values of differences between the calculated radio frequencies and multiplied frequencies of the changed drive frequency are greater than or equal to a predetermined value. The control unit changes the drive frequency to lessen a change width before and after the change by either increasing the drive frequency or decreasing the drive frequency.

Frequency control apparatus

A vehicular power transmission device includes a power transmission unit which transmits electromagnetic waves to a mobile device to transmit power to a power reception unit of the mobile device, and a frequency changing unit which, when it is determined based on the transmission frequency of the electromagnetic waves to be transmitted from the power transmission unit to the mobile device and a reception frequency of a radio receiver that radio noise is generated by the power transmission unit, changes the transmission frequency of the electromagnetic waves of the power transmission unit, wherein the power transmission unit changes a transmission power of the electromagnetic waves based on an amount of change in the transmission frequency of the electromagnetic waves changed by the frequency changing unit.

Vehicular power transmission device

A control system for a vehicle, capable of suppressing increase in power consumption and reducing running cost when electric power supplied from power source is consumed by an on-vehicle electric device. The control systemfor a vehicle V includes an ECU. If a predetermined communication state where a portable deviceis estimated to be in a compartment of the vehicle V is established (if the answer to the question of the stepis NO) after a state where a power source position set by a changeover switchis an accessory position has continued for a first predetermined time period (&#x394;T&#xb7;TREF), the ECUstops power supply from the power source to the on-vehicle electric device when a second predetermined time period (&#x394;T&#xb7;TREF) elapses after the predetermined communication state was established (steps).

Control system for vehicle

A vehicular electronic key system includes a vehicle having a key cylinder and a portable device. The portable devise includes a key body and a mechanical key. The key body is communicatable with the vehicle. The mechanical key is attachable to and detachable from the key body and mechanically rotates the key cylinder whereby the communication between the vehicle and the portable device allows the vehicle to execute predetermined functions. The key body includes a key detector configured to detect an attachment state and a detachment state of the mechanical key to and from the key body so that the key body transitions to a valet mode to limit some of the predetermined functions executable by the vehicle in accordance with the communication between the vehicle and the portable device while the key detector detects the detachment state of the mechanical key from the key body.

Vehicular electronic key system

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.

A counter increases a counted value at regular time intervals during a transmission time of a request signal Sr transmitted based on trigger signals input from a door unlocking sensor or the like. On the other hand, the counter decreases the counted value at regular time intervals during a non-transmission time of the request signal Sr. A determination unit either prohibits or permits transmission of the request signal Sr to a portable unit, based on comparison results of the counted value with a prohibition value and a lifting value.

Remote control device and remote control method for vehicle

The present invention provides an automatic locking/unlocking device which locks an opening/closing body when a normal response signal is received in response to a request signal sent to a predetermined zone around a vehicle body, comprising detector for detecting that the opening/closing body is closed, wherein the request signal is sent within the vehicle compartment in response to closing of the opening/closing body before the request signal is sent to the predetermined zone around the vehicle body and if the normal response signal is received in response to this request signal, transmission of the request signal to the predetermined zone around the vehicle body is prohibited, thereby suppressing consumption of power in the portable unit and ensuring a secure automatic locking.

Radio type locking/unlocking device

LF antennas are mounted respectively on the corners of a rear bumper of a vehicle. Radio waves radiated from the LF antennas mounted respectively on the corners of the rear bumper are propagated to the both surfaces of the vehicle on the opposite sides of the corner, providing effective transmission ranges. The remaining LF antennas are mounted respectively on the side surfaces of the vehicle such that their effective transmission ranges overlap the effective transmission ranges of the LF antennas mounted respectively on the corners of the rear bumper.

Remote door lock controller for vehicles

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.

Vehicular remote control system

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.

Remote control device for vehicles

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.

Vehicular door lock remote control apparatus

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.
