According to the present invention, when the power is supplied to the audio system, a voltage is applied to the antenna to detect whether the antenna is connected through a change in voltage, thereby preventing the reception sensitivity when listening to the broadcast when the antenna is not normally connected. It has an effect.

In particular, by applying a driving voltage to the antenna only when the antenna is normally connected, there is an advantage that can be unnecessary power consumption.

In addition, if the reception sensitivity is low when listening to the broadcast, simply because the antenna is not normally connected to diagnose whether the audio system itself is defective, there is an effect that can prevent unnecessary vehicle maintenance.

Hereinafter, preferred embodiments according to the present invention will be described in detail with reference to the accompanying drawings, with reference to the parts necessary for understanding the operation and operation according to the present invention.

Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the present invention.

1 is a block diagram schematically showing the configuration of a self-diagnostic vehicle audio system according to the present invention.

As shown in FIG. 1, the self-diagnostic vehicle audio system according to the present invention includes a power supply means 100, a detection means 200, a control means 300, and a display means 400.

The power supply means 100 checks the connection between the antenna 500 and the audio system with the detection means 200 to be described later when the power system is powered on, that is, when a power voltage is applied to the audio system. Apply the connection confirmation voltage.

In addition, the power supply means 100 applies or cuts a driving voltage to the antenna 500 according to an output signal of the control means 300 which will be described later, that is, a control signal.

For example, when the control signal is a signal for applying the driving voltage to the antenna 500, the power supply means 100 applies the driving voltage to the antenna 500, the control signal to cut the driving voltage to the antenna 500 In the case of a signal, the power supply means 100 cuts the driving voltage to the antenna 500.

The detection means 200 receives the connection confirmation voltage from the power supply means 100 and applies the voltage back to the antenna 500.

The detection means 200 detects whether the antenna 500 is connected by changing the connection confirmation voltage (for example, approximately 5V) applied to the antenna 500.

For example, when the antenna 500 and the in-vehicle audio system are abnormally connected, the detecting means 200 detects a voltage amount applied to the antenna 500, and the voltage smaller than the magnitude of the connection confirmation voltage applied to the antenna 500. , Approximately 0V), and when the antenna 500 and the vehicle audio system are normally connected, the detecting means 200 detects the magnitude of the voltage applied to the antenna 500 and is equal to the connection confirmation voltage applied to the antenna 500. A voltage of magnitude (eg, approximately 5V) is detected.

The voltages detected when the antenna connection is normal and abnormal are not limited thereto and can be modified as much as possible.

Here, the magnitude of the connection confirmation voltage is less than or equal to the driving voltage.

The control means 300 controls the display whether the connection with the antenna 500 according to the output signal of the detection means 200, that is, the detection signal, and controls whether or not the power is supplied to the antenna 500.

For example, the control means 300 is a power supply means so that the driving voltage is applied to the antenna 500 when the detection signal received from the detection means 200 detects that the connection between the antenna 500 and the vehicle audio system is normal. If the control unit 100 receives a signal detected from the detection means 200 that the connection between the antenna 500 and the in-vehicle audio system is abnormal, the power supply means 100 is controlled so that the driving voltage is blocked by the antenna. do.

In addition, when the detection signal received from the detection means 200 is a signal that detects that the connection between the antenna 500 and the in-vehicle audio system is normal, the control means 300 will be described later to indicate that the connection with the antenna 500 is normal. When the control means for the display means 400, and receives a signal detected from the detection means 200 that the connection between the antenna 500 and the in-vehicle audio system is abnormal, the display means to indicate that the connection with the antenna 500 is abnormal ( 400).

The display means 400 displays whether the antenna 500 is connected according to the output signal of the control means 300, that is, the control signal.

For example, when the control signal is a signal indicating that the connection with the antenna 500 is normal, the display means 400 indicates that the connection with the antenna 500 is normal, and the control signal is abnormal with the connection with the antenna 500. In the case of a signal indicating that the display means 400 indicates that the connection with the antenna 500 is abnormal.

Here, in the display method of the display means 400, an image or icon indicating that the connection is normal or abnormal is preset, and it is preferable to display the image or icon on the screen according to a control signal.

As shown in FIG. 2, the control means 300 determines whether or not to receive a signal that detects whether the antenna 500 is connected to the vehicle audio system (S200).

As a result of the determination, when the control unit 300 does not receive the detected signal, the control unit 300 continuously checks whether the corresponding signal is received.

However, as a result of the determination, when receiving the outstanding signal, the control means 300 determines whether the received signal is a signal for detecting the normal connection between the antenna 500 and the vehicle audio system (S210).

As a result of determination, when the detected signal is a signal that detects a normal connection between the antenna 500 and the vehicle audio system, the control means 300 controls the display means 400 to display a normal connection with the antenna 500. The power supply means 100 is controlled to apply the driving voltage to the antenna 500 (S220).

However, as a result of the determination, the control means 300 displays the display means 400 to display an abnormal connection with the antenna 500 when the detected signal is a signal that detects an abnormal connection between the antenna 500 and the vehicle audio system. The control unit 100 controls the power supply unit 100 to block the driving voltage with the antenna 500 (S230).
