Hereinafter, with reference to the accompanying drawings, the theft and damage warning method using a vehicle media playback device having an impact sensor of the present invention will be described in more detail.

First, the application environment of the theft and damage warning method using the media reproducing apparatus for automobiles provided with the impact sensor according to the present invention will be described. It is provided with a sensor for detecting a shock, and configured to output a warning sound by detecting the shock through the shock sensor. In this case, the control unit of the vehicle media player may control the warning output based on the shock detection value. In addition, the control unit of the vehicle media playback device may be connected to the control configuration of the vehicle and may be configured to enable control related to the operation of the vehicle in case of theft or damage.

3 is an exemplary flowchart of a theft and damage warning method using a media playback device for a vehicle having an impact sensor according to the present invention.

First, it is determined whether the shock detection is to be performed (S110). For example, if you are in a car, you will not need to carry out shock detection to warn you of theft or damage. Therefore, the driver determines to perform the shock detection when the driver is away.

Whether or not to perform such a shock detection may be basically performed by checking whether the vehicle is started. For example, when a person is in a car, a key is often inserted to start a car or to operate a media player for a car. Whether such a key is inserted can be checked electrically, for example in a control configuration inside the vehicle.

Therefore, if the control configuration inside the car and the vehicle media playback device are connected and configured to receive such a signal, it is determined that the shock detection is performed if the key is not inserted in the car, and the key is inserted into the car. If not, it may be determined that the shock detection does not need to be performed.

Alternatively, it may be determined whether a shock is detected through the button setting of the vehicle media player. For example, the driver may be configured to perform shock detection by pressing a mapped button or a combination of buttons to start the operation of the shock sensor provided in the vehicle media reproducing apparatus. Alternatively, pressing the button setting for releasing such a shock detection may be set not to perform a shock detection.

Alternatively, the controller may be configured to detect the boundary state setting of the vehicle equipped with the media reproducing apparatus for automobiles according to the present invention to determine whether the impact detection is performed. For example, an automobile may be additionally equipped with a burglar alarm function. It is also possible to determine whether shock detection is performed based on whether the driver has set the burglar alarm function.

If it is determined that the shock detection is performed in this manner, it is detected whether a shock is applied to the vehicle or the vehicle media playback apparatus through a sensor provided in the vehicle media playback apparatus (S120).

Such an impact may be caused by various causes.

For example, a shock may be detected even when a large car passes by and vibration is not transmitted or a direct shock is caused by an earthquake or the like, or an impact generated by an object hitting the car may be detected. Alternatively, a third party may impact the vehicle or the media player for the vehicle for theft.

Therefore, it is determined whether the shock value detected through the shock sensor for the impact of the various causes is more than a threshold value that can be considered as theft or damage (S130).

This threshold may be set variously according to the impact detection purpose.

For example, either the minimum impact value determined as theft of the vehicle media player or the minimum impact value determined as the damage of the car equipped with the vehicle media player is preset and stored. This threshold can be set through experiments on the assumption of various cases.

Alternatively, for example, the vehicle media player according to the present invention may include a button for setting a threshold value, and the threshold value may be set based on the button. That is, for example, the threshold is set step by step according to the degree of impact detection from step 1 to step 10, such as through the volume control knob. In this case, step 1 is the most sensitive and can detect even the most sensitive shocks.

In this case, the threshold value designation may be set based on a shock detection value for each stage designated in advance to correspond to the step set by the driver through the threshold setting button.

Thereafter, if the detected shock value is equal to or greater than the above-described threshold value, the controller outputs a warning (S140). In other words, control is performed to warn of car breakdown or theft of a media playback device for a vehicle.

Such warning control can be controlled to output a warning sound at a high volume to a connected speaker, for example, through a control configuration of a vehicle media playback device.

Alternatively, a warning sound may be output through the horn of the vehicle equipped with the vehicle media reproducing apparatus.

Or it may be configured to output a warning through the vehicle control, such as flashing the emergency light of the vehicle or operating the wiper.

Such a warning output may be implemented by transmitting a control signal to the control configuration of the vehicle in the control unit of the vehicle media playback device.

Although the configuration of the present invention has been described in detail, it is only for illustrating the present invention, and the protection scope of the present invention is not limited thereto, and the protection scope of the present invention is defined through the description of the claims.

As described above, according to the present invention, when a shock sensor is provided in an automotive media player, when an external shock is applied to the vehicle or the media player is removed for the purpose of theft, the vehicle speaker or a horn in the vehicle may be stolen. Can be prevented in advance or the car can be damaged.
