Abstract
Abstract An apparatus remotely controls, for example, door locking/unlocking and alarm activation of an automobile. A transmitting device transmits communication data, which includes synchronization data and identification data. The communication data is received by the control apparatus in which the identification data included in the received communication data is compared with already stored data. The locking and unlocking of the doors of the vehicle is carried out when the identification data matches the already stored data. A continuous reception condition is detected when the communication data is received for more than a predetermined period of time. When the continuous reception condition is detected, an alarm is actuated. As such, a common transmitting button of the transmitting device can be used to effect both control of the locking and unlocking of doors and alarm activation. The control apparatus may also include an erasable memory which is remotely settable in a writable status and in which identification data can be erased by remote control while in the writable status.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
280 words
An apparatus for remotely controlling an automotive vehicle provided with a transmitting apparatus, having a transmission button, for repeatedly transmitting a communication data which includes a synchronization data and an identification data upon manipulation of the transmission button, and a theft preventing apparatus for controlling respective parts of the vehicle upon receipt of the communication data transmitted from the transmitting apparatus, said control apparatus comprising: means for discriminating whether the synchronizing data and the identification data included in the received communication data respectively match prestored synchronizing data and prestored identification data stored in a memory in advance; means for controlling a locking and unlocking of doors of the vehicle when the discrimination means discriminates that synchronizing data and the identification data respectively match the prestored synchronizing data and prestored identification data; means for determining whether continuous reception of the communication data has been effected in which the communication data is continuously repeatedly received for more than a predetermined period of time; and means for actuating an alarming theft prevention apparatus provided in the vehicle when the determining means determines that the continuous reception has been effected, the determining means setting a respective determination basis for each of the synchronization data and the identification data, each determination basis defining a degree of coincidence between received and prestored data, repeatedly comparing the synchronization data and the identification data included in the communication data with the prestored synchronization data and the prestored identification data, respectively, and determining that the continuous reception of the communication data has been effected when the determination basis of the synchronization data and the determination basis of the identification data are each satisfied during the predetermined period of time.
