Abstract

PURPOSE: A navigation system interlocking with a winker and a control method thereof are provided to improve vehicle performance by automatically controlling a winker using a GPS signal. CONSTITUTION: A navigation system(20) interlocking with a winker comprises a gyro sensor(220), a GPS module(210), and a controller(240). The gyro sensor outputs first and second voltage when the direction of a vehicle is left and right using a GPS signal. The GPS module extracts the angular acceleration of the vehicle using the GPS signal. The controller determines whether a winker is lightened or not using the entering angle of the vehicle confirmed from the angular acceleration. When it is determined that the winker is lightened, the controller transmits a lighting signal to a dashboard.

It is provided to fully convey the scope of the invention to those skilled in the art, and the present invention is defined only by the scope of the claims. It is to be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. In the present specification, the singular form includes plural forms unless otherwise specified in the specification. As used herein, “comprises” and / or “comprising” refers to a component, step, operation and / or device that is present in one or more other components, steps, operations and / or elements. Or does not exclude additions.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Figure 2a is a block diagram showing a direction indicator interlocking navigation system according to an embodiment of the present invention, Figure 2b is a block diagram showing the instrument panel and the direction indicator of the vehicle associated with it.

As shown in FIG. 2A, the direction indicator interlocked navigation system 20 according to the embodiment of the present invention includes a gyro sensor 220, a GPS module 210, an ADC 230, and a controller 240.

The gyro sensor 220 outputs first and second voltages having different levels when the direction of the vehicle is to the left and to the right by using the GPS signal received by the GPS antenna.

Here, the first and second voltages are voltages for distinguishing the entrance direction of the vehicle. For example, the first voltage may be a voltage of 2.5V or more, which is a front reference voltage, and the second voltage may be less than 2.5V.

The ADC 230 converts the first voltage or the second voltage into an analog-digital signal and transmits the analog-digital signal to the controller 240.

The GPS module 210 extracts the angular acceleration of the vehicle using the received GPS signal.

The controller 240 determines whether the direction indicator light is turned on by using the entrance angle of the vehicle identified from the angular acceleration, and checks the entrance direction of the vehicle from the first or second voltage. At this time, the control unit 240 may determine the lighting of the direction indicator when the entrance angle of the vehicle is greater than the predetermined threshold value.

When the controller 240 decides to turn on the turn indicator, the controller 240 generates a turn signal indicating the turning on of the left or right turn indicator corresponding to the direction of entry of the vehicle, and transmits the turn signal to the instrument panel 250 through the vehicle network.

Herein, the control unit 240 may be a central processing unit and / or a microcomputer, and may provide at least one interface of a UART, I2C, Group Policy Management Console (GPMC), and a vehicle network (MOST / CAN).

Subsequently, the instrument panel 250 receives a lighting signal through the vehicle network, and performs control of lighting the left or right direction indicator 261 or 262 according to the lighting signal.

On the other hand, the control unit 240, for example, in case there is a difference in the operation time of the entry angle and the entry direction may store the entry angle and the entry direction confirmed in the provided memory.

As such, the turn indicator interlocked navigation system 20 may drive the left or right turn indicators 261 or 262 using the instrument panel 250 without providing a separate turn indicator drive unit, thereby providing its own hardware and software algorithm. Can be simplified.

Hereinafter, referring to FIG. 3, a method of controlling a navigation light interlocking navigation system according to an exemplary embodiment of the present invention will be described. FIG. 3 is a flowchart illustrating a method of controlling a navigation indicator interlocked navigation in accordance with an embodiment of the present invention.

Referring to FIG. 3, the direction indicator interlocked navigation system 20 receives a GPS signal (S310).

Subsequently, the direction indicator interlocked navigation system 20 inputs a GPS signal to the gyro sensor and outputs left / right reference voltages having different levels when the vehicle enters the left side and the right side (S320).

Next, the direction indicator light interlocked navigation system 20 checks the entry direction of the vehicle using the left / right reference voltage (S330).

On the other hand, the direction indicator light interlocked navigation system 20 uses the GPS signal to determine the entry angle of the vehicle based on the front (S340).

In detail, the direction indicator interlocked navigation system 20 may extract the angular acceleration from the GPS signal and determine the entry angle of the vehicle by the angular acceleration using a preset equation.

In addition, the direction indicator interlocked navigation system 20 checks whether the entrance angle is greater than or equal to the threshold value (S350).

At this time, when the direction indicator light interlocked navigation system 20 confirms that the entrance angle of the vehicle is greater than or equal to the threshold value, the direction indicator lights are turned on (S360).

Subsequently, the direction indicator interlocked navigation system 20 confirms whether the direction of entry of the vehicle is to the left or the right, and transmits a lighting signal for instructing to turn on the direction indicator corresponding to the direction of entry of the vehicle, and thereby the instrument panel transmits. The left / right turn indicator corresponding to the turned on signal is turned on (S370).

As described above, the present invention can automatically control the direction indicator light, which has been operated manually in the past, using a GPS signal, thereby improving vehicle performance and driving convenience.

In addition, the present invention can remove the direction indicator lever itself from the vehicle by replacing the lever function of the direction indicator, so that the assembly process can be simplified, the weight of the vehicle can be reduced, and environmentally friendly.

While the present invention has been described in detail with reference to the accompanying drawings, it is to be understood that the invention is not limited to the above-described embodiments. Those skilled in the art will appreciate that various modifications, Of course, this is possible. Accordingly, the scope of protection of the present invention should not be limited to the above-described embodiments, but should be determined by the description of the following claims.
