First, the order in which the method for providing wheel direction information of a vehicle according to an exemplary embodiment of the present invention will be described will be described with reference to FIG. 1.

1 is a flowchart illustrating a sequence of implementing wheel direction information providing method of a vehicle according to an exemplary embodiment of the present invention.

As shown in FIG. 1, the method for providing vehicle wheel direction information according to the present invention first detects the degree of rotation of the steering wheel of the vehicle (S100).

The detection of the degree of rotation of the steering wheel is not limited as long as it is a sensor capable of detecting the degree of rotation, such a sensor is a sensor using the principle of the gyroscope (gyroscope) that can detect the degree of rotation (gyro sensor) B, a gravity sensor called a G sensor capable of detecting the degree of movement of an object using gravity, and a sensor using a touch sensor as shown in FIGS. 3 and 4 are possible.

3 and 4 will be described in more detail with respect to the case of implementing a sensor for detecting the degree of rotation or the movement of an object using a touch sensor.

On the other hand, when the degree of rotation of the steering wheel is detected, the degree of rotation of the steering wheel and the wheel position information of the vehicle are matched (S102).

Matching the rotational degree of the steering wheel and the wheel position information of the vehicle may be set in advance by inputting information on the degree of movement of the wheel shaft according to the degree of rotation of the steering wheel.

For example, in case of vehicle A, the wheel axle of the vehicle moves 45 degrees in the front direction when the steering wheel is rotated once, but in case of vehicle B, the wheel axle of the vehicle moves only 30 degrees in the front direction when the steering wheel is rotated once. In some cases.

In order to accurately display the difference between the degree of rotation of the steering wheel and the degree of movement of the wheel shaft of the vehicle according to the vehicle, the necessary information is input in advance and set by the user.

After the rotation degree of the steering wheel is matched with the wheel position information of the vehicle, the wheel position information of the vehicle is displayed through the display device using the matched information (S104).

Displaying the wheel position information of the vehicle is not limited as long as the user can recognize the wheel position information of the vehicle.

The display of the vehicle wheel position information is, for example, a method of displaying the wheels of the vehicle on a display device such as an LCD (Liquid Crystal Display) and displaying on the display device how much the wheels of the vehicle are moved, or simply the wheels of the vehicle are moved. It is possible to display a piece of information with a direction and a number (eg, L (left) 45 when it is located 45 degrees to the left).

In addition, as described above, when it is attached to the steering wheel to detect the degree of rotation of the steering wheel, it is also possible to display the degree of rotation of the steering wheel rather than the wheel position information of the vehicle.

For example, when the steering wheel is rotated one turn to the left, the display may be displayed as L1, and it is possible to realize a simpler form, but to allow the driver to easily recognize that the current steering wheel is rotated one turn to the left.

Hereinafter, a configuration of an apparatus for implementing the method of providing wheel direction information of the vehicle will be described with reference to FIG. 2.

The signal conversion unit 210 matches the rotational degree of the steering wheel detected by the sensor unit 200 with the wheel position information of the vehicle and outputs a signal corresponding to the matched information, thereby displaying the wheel position information of the vehicle on the display unit 220. To be displayed.

On the other hand, when it is attached to the steering wheel to detect the degree of rotation of the steering wheel, it is also possible to display the degree of rotation of the steering wheel rather than the wheel position information of the vehicle, in this case, the signal conversion unit 210 to the degree of rotation of the steering wheel It is obvious that the corresponding signal can be output accordingly.

The display unit 220 includes a display window such as an LCD so that the degree of rotation of the steering wheel or wheel position information of the vehicle corresponding thereto is displayed according to the signal output from the signal converter 210.

Meanwhile, although not shown in FIG. 2, as described above, the degree of movement of the wheels of the vehicle according to the degree of movement of the steering wheel may vary according to the type of the vehicle, so that the rotational degree of the steering wheel and the wheel position information of the vehicle are set in advance. It may further include a setting unit to make.

In addition, although not shown in Figure 2, such a wheel position information providing apparatus of the vehicle may further include a power supply for supplying power for each component to operate.

Can be connected and powered.

Meanwhile, in the present invention, the wheel position information of the vehicle is provided to the driver by displaying the rotation degree of the steering wheel or the wheel position information of the vehicle corresponding thereto using the degree of rotation of the steering wheel.

The degree of rotation of the steering wheel can be detected using a device such as a gyro sensor or a gravity sensor that can detect rotation, but it is also possible to detect the degree of rotation of the steering wheel with a touch sensor using the structure of the sensor unit itself.

Hereinafter, referring to FIGS. 3 and 4, when the sensor of the wheel direction information providing apparatus of the vehicle according to the present invention is implemented as a touch sensor, a structure thereof and a method of detecting a degree of rotation of the steering wheel using the same will be described. do.

First, FIG. 3 is an exemplary view illustrating a form of a sensor of a wheel direction information providing apparatus of a vehicle according to an exemplary embodiment of the present invention using a touch sensor.
