ABSTRACT:
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.
