    摘要: A vehicle start-up permission device in which an identification code stored in an electronic key can be kept secret. A start-up permission ECU (1) is magnetically coupled with a transmit-receive controlling circuit (6) of an electronic key (3) via an antenna (2) and an antenna (5) of the electronic key (3) with the electronic key (3) being inserted in an ignition key (4) so as to supply electric power for the circuit. When the ignition switch (4) is operated to an ACC position, the start-up permission ECU (1) transmits a random number code. When the transmit-receive controlling circuit (6) of the electronic key (3) receives the random number code, it converts by predetermined encryption processing a previously registered key code to a return code on the basis of the random number code and returns the return code. When the start-up permission ECU (1) receives the return code, it decodes a key code on the basis of the random number code, and when the key code coincides with the previously registered key code, the start-up permission ECU (1) outputs a start-up permission signal to an engine-controlling ECU (7).

    摘要: In a vehicular communication system, a microcomputer of a transmission-reception electronic control unit (ECU) transmits stored data via an antenna coil to a transceiver disposed in an ignition key when the ignition key is inserted in an ignition key cylinder of a vehicle. During communication with the transceiver, the microcomputer outputs a key interlock actuating signal. While the key interlock actuating signal is being inputted to a key interlock control circuit, the key interlock control circuit operates a key interlock actuator to prevent the ignition key cylinder from being turned to a position at which the ignition key may be freely removed from the ignition key cylinder. Thus, the ignition key is prevented from being removed from the ignition key cylinder during communication between the ignition key transceiver and the microcomputer, thereby ensuring that data about the vehicle will be stored in a reception device disposed in the ignition key without a failure.

    摘要: The invention relates to a transmission-reception system. A transponder receiver unit contained in the key bow of an ignition key has a power circuit that receivers, rectifies and smoothes the carrier wave signal transmitted together with a time reference signal and an enquiry signal from the transmission-reception ECU of a motor vehicle. A microcomputer in the transponder becomes active when the output voltage of the power circuit reaches a predetermined level or higher. When activated, the microcomputer measures the time length of the received reference time signal using the clock signal generated by an oscillation circuit, and calculates a ratio, as a correction coefficient, between the measured time length and a stored reference time value. The microcomputer decodes the enquiry signal while correcting the time information included in the time series pulse signal forming the enquiry signal, using the correction coefficient.

    摘要: A microcomputer includes therein an operation control part which can be operated when a clock signal is applied thereto by an oscillation circuit. If the operation control part reads out an identification code from an EEPROM, then it switches a control signal to be given to a switching element in accordance with the levels of the respective bits. When the control signal is off, the oscillation frequency of the oscillation circuit is F1. On the other hand, if the control signal is turned on, then one terminal of a capacitor is grounded to thereby switch the oscillation frequency over to F2. The clock signal is divided by a frequency dividing circuit before it is output. The frequency of the output signal after being divided becomes f1 or f2 in accordance with the above switching and the output signal is transmitted in the form of a frequency modulation signal.

    摘要: When an engine is started with a key 19A inserted in an ignition key cylinder of a vehicle 11, a vehicle-side controller 12 transmits operational data to the key 19A and stores in the key 19A. Further, when a personal computer 30 is operated with the key 19A inserted in an R/W device 31, the R/W device 31 reads the operational data from the key 19A and transfers to the personal computer 30. In this structure, when a storage capacity of the key 19A becomes full, the vehicle-side controller 12 stores the operational data in a storage portion of its own, and when the key 19A is initialized, the stored operational data is written in the key 19A. For this reason, even when initialization of the key 19A is difficult, deletion of the operational data is prevented.

    摘要: The invention relates to a transmission-reception system, particularly a transmitter-receiver device contained in the bow of an ignition key. When a resonance circuit receives a carrier wave signal from a transmission-reception ECU of a motor vehicle, a microcomputer is switched to an active state by the output of a power circuit that smoothes and rectifies the carrier wave signal. A detector circuit discriminates an enquiry signal supplied together with the carrier wave signal through the resonance circuit portion, and outputs the signal to the microcomputer. In response to the enquiry signal together with random number data, the activated microcomputer changes the bit length of an identification code stored in an EEPROM, on the basis of the received random number data and a predetermined function, and performs the on-off control of an FET of a modulating circuit in a mode corresponding to the bit length-changed identification code. The microcomputer thus performs control to send back an enciphered answer signal to the transmission-reception ECU.

    摘要: A vehicular door lock control apparatus for unlocking a door lock mechanism includes a key for performing a first unlocking operation and a second unlocking operation. A door key cylinder is actuable to an unlock position by using the key. The key is insertable into the door key cylinder. A transmitter-receiver is disposed at the key, and transmits an answer signal that indicates a specific identification code upon receipt of at least one of a power signal and an inquiry signal. An operating force transmission mechanism, actuable between a transmission mode and a non-transmission mode, transmits an unlocking force applied by the key during the second unlocking operation to the door lock mechanism when in the transmission mode. A control mechanism transmits at least one of the power signal and the inquiry signal to the transmitter-receiver when the key performs the first unlocking operation, and actuates the operating force transmission mechanism to the transmission mode when the identification code received from the transmitter-receiver conforms to a pre-set identification code.
