4 is a flowchart illustrating a driver warning method according to an embodiment of the present invention.

Referring to FIG. 4, a driver warning method for placing a mobile phone on a wireless charger and warning a driver to get off the vehicle is as follows.

First, it is checked whether or not the driver gets off the vehicle (S110).

For example, it is possible to check whether a driver is getting off by sensing whether the door of the vehicle is opened or closed by using a door sensor.

As another example, it is possible to detect the stop of the engine by using the engine sensor and to see that the driver's door of the vehicle is opened using the door sensor in a state where the engine is stopped, thereby confirming that the driver gets off the vehicle.

As another example, it can be confirmed that the load of the driver is detected by the load sensor provided in the driver's seat of the vehicle, and the driver gets off the vehicle when the load of the driver is not detected in the load sensor. At this time, when the load of the driver is not detected in the load sensor for a predetermined period of time, it can be confirmed that the driver gets off the vehicle.

As another example, it can be confirmed that when the driver's load is not detected in the load sensor provided in the driver's seat of the vehicle, and the driver's door is opened in the door sensor, the driver gets off the vehicle.

If the driver's departure is not confirmed, repeat until the driver's departure is confirmed.

When the driver gets off the car, it is checked whether the mobile phone is present on the wireless charger (S120).

Specifically, whether a mobile phone is present on the wireless charger is checked according to whether a packet signal is received from the mobile phone to the wireless charger. That is, when the communicator of the wireless charger receives the packet signal, it is determined that the mobile phone exists on the wireless charger. If the communicator does not receive the packet signal, the mobile phone does not exist on the wireless charger .

As another example, the presence or absence of a cellular phone on the wireless charger can be checked according to whether a wireless communication signal is received from the cellular phone to the wireless charger. When the wireless communication signal receiver of the wireless charger receives the wireless communication signal of the mobile phone, it determines that the mobile phone exists on the wireless charger. Examples of the wireless communication include Bluetooth, Wi-Fi, NFC, and the like.

When the wireless communication signal receiver receives the wireless communication signal, it can selectively receive only a specific wireless communication signal generated in the predetermined mobile phone. Therefore, it is possible to prevent the wireless communication signal receiver from receiving a wireless communication signal generated from another mobile phone.

As another example, by sensing the load of the mobile phone placed on the wireless charger with the load sensor, it can be confirmed whether the mobile phone is located on the wireless charger. The load sensor can detect that the mobile phone is located on the wireless charger only when a load of a predetermined range including the weight of the mobile phone is detected because the mobile phone can put an object other than the mobile phone on the wireless charger .

As another example, the presence of the mobile phone may be detected by sensing a mobile phone placed on the wireless charger as a proximity sensor. The mobile phone can detect that the mobile phone is located on the wireless charger when the mobile phone is continuously detected by the proximity sensor for a preset time to prevent malfunction due to temporary access of the object.

If the mobile phone is not detected on the wireless charger, it can be determined that the driver has taken off the mobile phone. Therefore, if the cellular phone is not detected on the wireless charger, the driver is checked again to warn the driver.

Next, if the driver confirms the getting off of the mobile phone and confirms the presence of the mobile phone on the charger, a warning is issued (S130) that the driver places the mobile phone on the wireless charger.

The warning may be indicated by blinking of sound, voice, warning light.

The vehicle warning method can prevent the loss of the mobile phone and prevent the explosion of the battery of the mobile phone due to the high temperature inside the vehicle because the mobile phone can be placed on the wireless charger and the driver can warn him or her from the vehicle .

INDUSTRIAL APPLICABILITY As described above, the vehicle warning system and method according to the present invention can improve the convenience and stability of the driver by preventing the cellular phone from being lost or exploded.

In addition, the vehicle warning system can use a vehicle control module, a CAN communication, a buzzer, etc. of an existing vehicle as it is, thereby minimizing the addition of components. Therefore, the installation cost of the vehicle warning system can be reduced.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the present invention as defined by the following claims. It can be understood that it is possible.
