Missing vehicle detection system by using a car audio system
First Claim
1. A car audio for transmitting a missing vehicle signal, the car audio comprising:
- a keyboard having a plurality of keys and for generating a key signal corresponding to one of the plurality of keys which is selected;
a radio part for receiving a broadcasting signal and producing a first audio signal which is included in the broadcasting signal;
a cassette deck part for reproducing a second audio signal which is recorded on a cassette tape;
an audio part for driving at least one speaker according to either the first audio signal or the second audio signal;
a memory for storing a password and a license plate number;
a transmission part for generating a missing vehicle signal on the basis of the license plate number and for transmitting the missing vehicle signal through a transmission antenna;
a display for displaying messages; and
a control part for controlling each of the radio part, the cassette deck part, the audio part, the transmission part, and the display in response to at least one key signal generated from the keyboard, the control part for determining whether the car audio is initiated based on an inputting of power to the car audio,wherein the control part causes the display to display a message requesting to input the password and causes the audio part to mute outputting of an audio sound when the control part determines that the car audio is initiated,wherein the control part causes the audio part to output the audio sound and determines whether the key signals are identical with the password stored in the memory when key signals are inputted from the keyboard,wherein the control part causes the transmission part to transmit the missing vehicle signal when the key signals are different from the password stored in the memory.

Abstract
A system which can detect a vehicle that is missing or stolen on the basis of a missing vehicle signal which is transmitted from a car audio system in which a transmission apparatus is installed for transmitting the missing vehicle signal. When the car audio is initiated, a transmission control part causes a first display to show a message requesting to input a password and causes an audio part to mute an outputting of the audio sound. When the password is inputted by a keyboard, the control part causes an audio part to stop muting the audio sound, and causes a transmission part to transmit the missing vehicle signal when the password inputted from the keyboard is different from a password stored in a first memory. A receiving apparatus includes an alarm generation part for ringing an alarm sound, a receiving part for receiving the missing vehicle signal, a demodulation part for demodulating the missing vehicle signal in order to detect data included in the missing vehicle signal, a modem for transmitting the data through a telephone line, and a receiving control part for controlling the alarm generation part, the display, and the modem according to whether the receiving part receives the missing vehicle signal or not.

2. A system for detecting a missing vehicle comprising:
-
a car audio which includes an audio part and a transmission apparatus, wherein the audio part includes a keyboard, a tuner, a cassette deck, and a circuit for driving one or more speakers according to an audio signal from either the tuner or the cassette deck in order to output an audio sound, and the transmission apparatus includes a first memory for storing a password and a license plate number of the missing vehicle therein, a transmission part for transmitting a missing vehicle signal based on data stored in the first memory, a first display for displaying messages showing a current operation state of the car audio, and a transmission control part for controlling the car audio, the transmission part, and the display according to a key signal inputted from the keyboard and whether the car audio is initiated, wherein when the car audio is initiated, the transmission control part causes the first display to show a message requesting to input the password and causes the car audio to mute an outputting of the audio sound, wherein when the password is inputted by the keyboard, the control part causes the muting means to stop muting the audio sound, and causes the transmission part to transmit the missing vehicle signal when the password inputted from the keyboard is different from the password stored in the first memory; and a receiving apparatus which includes an alarm generation part for ringing an alarm sound, a receiving part for receiving the missing vehicle signal, a demodulation part for demodulating the missing vehicle signal in order to detect data included in the missing vehicle signal, a modem for transmitting the data through a telephone line, and a receiving control part for controlling the alarm generation part, the display, and the modem depending on whether the receiving part receives the missing vehicle signal or not. - View Dependent Claims (3, 4)
