Also, as used herein, "comprising" or "comprising" means to refer to the presence or addition of one or more other components, steps, operations and elements.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

A vehicle system for connecting a vehicle and an external device (external lamp) includes an external device (external lamp), a control unit, a key switch, a switching device, and an IPS (Intelligent Power Switch) device.

The external device is a terminal such as an external lamp, and is a terminal through which a device can be connected to a console of a vehicle. When the switching device is turned on, the power supplied from the battery is supplied to the external lamp through the IPS device.

The control unit is referred to as a microcomputer or a microcomputer, and is connected to a kiss position, a switching device, and an IPS device.

In addition, the control unit receives the power selected from the user in the cluster of the vehicle, and receives the key position condition. The ON or OFF state of the switching device can be controlled according to the input power condition and the key position condition.

In addition, the control unit receives the sensed current from the IPS device, automatically calculates the average value of the sensed current, and turns off the switching element when a current equal to or higher than the average value flows after a predetermined time to protect the external device have.

The key position allows the user to select the type of power source from the battery power, or from the ACC power source or the ignition power source. If the external device is connected to the battery power without such a key position, the battery discharge will occur rapidly.

The switching element is an element that controls whether or not the power source is applied from the battery. The switching element is turned on or off according to the power application condition of the controller, so that power corresponding to the power condition selected by the user is not provided or provided to the external device through the IPS element.

The IPS device is a semiconductor device capable of replacing a fuse and senses a current supplied to an external device and transmits it to the control unit. That is, the IPS device measures the amount of current supplied to the external device, and then transmits the measured amount of current to the control unit.

FIG. 1 is a view for explaining a method of notifying a lamp of a vehicle according to an embodiment of the present invention.

Referring to FIG. 1, when the driver completes driving, the ignition of the vehicle is turned off (S11).

Next, when the door of the vehicle is locked by controlling the door of the vehicle, all external lamps of the vehicle are turned on and off once (S13 to S15).

Here, all external lamps mean a single-wire detection lamp (target lamp), and several or several ten disconnection detection lamps may be provided depending on the type of vehicle, and various disconnection detection lamps may be provided in the vehicle.

Next, the control unit of the vehicle informs the driver that the vehicle is in the locked state, and the current lamp load current value (current value of the sensed target lamp) and the lamp current reference current value (Open Current Limitation, OCL (S17).

Here, when the lamp disconnection reference current value OCL is smaller than the current lamp load current value, the lamp disconnection reference current value OCL is compared with another lamp load current value (S17 to S19). These different lamp load current values may be generally set to about 14 to 30 because the options vary depending on the vehicle type.

For example, the first lamp load current value and the lamp disconnection reference current value OCL among the other lamp load current values are compared, and the second lamp load current value and the lamp disconnection current value OCL are compared in sequence All lamp load current values can be compared.

Although FIG. 1 illustrates the case where the current value of the sensed target lamp is 16, the number of current values of the sensed target lamp that is compared with the lamp disconnection reference current value OCL can be adjusted.

However, after comparing the lamp disconnection reference current value OCL of all external lamps with the current lamp load current value, disconnection of all external lamps may not be detected (S20).

Next, if the lamp disconnection reference current value OCL is larger than the current lamp load current value, the control unit of the vehicle detects disconnection of the lamp (S21).

Next, the control unit of the vehicle stores the detected break information of the lamp (S23).

Here, after storing the disconnection information of the detected lamp, the disconnection information of the lamp may be provided as a proactive notification service using an application of the driver, or may be provided to the driver's vehicle using an A / S center located near the vehicle And may be transmitted so as to receive a prior service (S25 to S27).

Next, the controller of the vehicle judges whether the vehicle is turned on or off. When the vehicle is turned on, disconnection information of the stored lamp is displayed on the cluster (S29 to S31).

Next, the driver can easily grasp the lamp disconnection information because the disconnection information of the lamp is displayed in the cluster, and the controller of the vehicle can perform the conventional lamp disconnection detection algorithm after the vehicle is turned on (S33).

As described above, according to the present invention, all external lamps are output when the door of the vehicle is locked after the start-off of the vehicle to detect whether the lamp is broken or not, and the driver is informed whether the lamp is broken when the vehicle is restarted , And the safety of the driver can be ensured.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, Various modifications and variations may be made without departing from the scope of the appended claims.
