Hereinafter, a wheel alignment display device of the present invention will be described in detail with reference to the accompanying drawings.

The present invention is a device for assisting the driver's driving operation by visually displaying the movement state of the wheel according to the steering wheel operation state of the vehicle, in particular to transmit and receive data using an infrared signal. Obviously, it is possible to configure not only an infrared signal but also a radio frequency signal.

1 is a schematic diagram showing the configuration of a wheel alignment display device according to the present invention.

As shown, the wheel alignment display device of the present invention is largely divided into a position detection / transmission unit 10 and a position reception / display unit 20. The position detection / transmission unit 10 is for detecting the position movement of the handle and the position reception / display unit 20 is a device for displaying the steering state of the wheel according to the detected position of the handle.

The handle position rotation signal detected by the position detection / transmitter 10 is wirelessly transmitted in the present invention through an infrared signal. The position detecting / transmitting unit 10 uses a magnet and a hole detecting sensor, respectively, to detect the rotation angle of the handle on the fixed part and the moving part of the handle to detect the movement state of the handle, which will be described later.

2 is a block diagram showing a schematic configuration of the position detection / transmission section 10 according to the present invention. As shown, the hall sensor detecting unit 100, the control unit 110, the encoder 130, and the infrared ray transmitting unit 120 is included. Also connected is a power supply 140 for supplying power throughout the device.

The hall sensor detecting unit 100 is for detecting the rotational state of the steering wheel by using the hall sensor, the rotating part of the handle, that is, the part rotated by the driver to grip the hand to change the direction of the vehicle, the high of the handle The government, i.e., supports the handle so that it can rotate freely, is installed in each of the non-rotating parts.

The hall sensor detecting unit 100 is attached to the rotating portion of the handle, for example, a circular magnet (Ф 10 or less), and the fixing portion of the handle is attached to a plurality of Hall IC sensors in a circular shape corresponding to the circular magnet in accordance with the rotation of the rotating portion It is configured to detect the position of the hall sensor to determine the position of the handle. Therefore, when the rotating part of the handle is rotated, a different signal is generated according to the position from the hall sensor corresponding to the circular magnet installed therein.

Figure 6 shows the installation state of the Hall sensors 104 installed in the fixed portion of the handle. As shown, located in the center of the handle 102 and supports to rotate stably to the handle 102, itself A plurality of Hall sensors 104 are installed at fixed intervals at fixed intervals without rotation. Although not shown in the figure, the circular magnet may be installed at a predetermined position of the handle 102. Of course, it can be configured using other means for detecting the rotation of the handle as described above, for example, a means using a gear, which can also be said to belong to the scope of the present invention.

The signal generated from the hall sensor by the movement of the circular magnet is input to the controller 110. The control unit 110 modulates the signal through the encoder 130 after receiving the signal from the hall sensor detecting unit 100. The modulated signal is again converted into an infrared signal through the infrared transmitter 120 and then propagated to the air. The controller 110 may be configured using one chip microcomputer. In addition, it is apparent that the encoder 130 may be configured by using an embedded type in the controller 110 or by using an external type if it is not included in the controller 110.

The power supply unit 140 supplies power required for the position detection / transmission unit 10, and may be used by connecting a battery of a vehicle. Position detection / transmission unit 10 should be configured in consideration of the convenience of use and installation, it is preferable to use a double-sided tape or the like to be easily removable.

The signal transmitted from the position detection / transmission unit 10 having the above configuration is received and processed by the position reception / display unit 20. As shown in FIG. 3, the position receiving / displaying unit 20 includes an infrared receiving unit 210, a control unit 220, a decoder 230, an LCD display unit 250, or an LED display unit 260. . The indicators show examples of those that can be optionally used.

The infrared receiver 210 receives an infrared signal transmitted from the infrared transmitter 120 and modulates it into an electrical signal. After the signal modulated through the infrared receiver 210 is input to the controller 220, the decoder 230 processes and outputs the original signal. At this time, the signal demodulated by the decoder 230 is a signal for the steering wheel position of the vehicle, and the controller 220 extracts the position data of the wheel based on the signal. The wheel position data is measured in advance and then stored in the memory device of the controller 220.

The controller 220 may be configured using one chip microcomputer. In addition, the decoder 230 may be configured by using the one built in the control unit 220 or by using an external type if not included in the control unit 220.

The signal output after being modulated by the decoder 230 is input to the LCD display 250 or the LED display 260. According to the input signal, the display unit visually displays the wheel position so that the driver can recognize it. The displays are selectable. When the LCD display unit 250 is installed, since power consumed by itself is small, there is an advantage in that it can be driven using its own internal battery. In contrast, the LED display unit 260 preferably uses a DC power source provided in a vehicle in consideration of battery consumption. These displays can be selectively applied according to the type of vehicle.

4 shows an example of the panel of the position receiving / display unit 20 described above.

As shown, the IR receiving window 32, the set switch 34, the adjustment switch 36, and the display window 40 are displayed on the front surface. Displayed inside the display window 40 shows the steering state of the wheel, the arrow indicates the forward direction.

The IR receiving window 32 is for detecting an infrared signal transmitted from the infrared transmitting unit 140 of the handle position detecting unit 10. At this time, since the infrared signal is straight, it is required to install the transceivers at opposite positions for accurate reception of the signal. The set switch 34 is a switch used to set the position of the handle and the position of the wheel displayed through the display window of the LCD display 250 or the LED display 260. The adjustment switch 36 is also used to rotate the handle to the left and to adjust the position of the actual wheels and the position on the display window.

In the case of wheel marking, it is necessary to set the rotation angle of the steering wheel and the steering angle of the wheel accurately in consideration of the advantage because the rotation angle of the steering wheel is about 540 °.

The correspondence between the handle and the wheel adjusted as described above is stored in the internal memory of the controller 220, and later used as reference data to display the movement state of the wheel according to the operation of the handle. As described above, by adjusting the position of the wheel displayed on the LCD display 250 or the LED display 260 after moving the handle to one side, there is an advantage that the wheel alignment display of the present invention can be applied to all vehicles. The panel is preferably located on the front instrument panel of the handle for easy recognition by the operator.

An operation state of the wheel alignment display device of the present invention configured as described above will be described with reference to FIG. 5.

The vehicle first sets the steering wheel position and the corresponding wheel position for each vehicle before driving. This is set using the set switch 34 and the adjustment switch 36 provided in the position reception / display section 20 as described above. The handle movement and wheel movement data thereof set as described above are stored in the internal memory device of the controller 220.

When the driver drives the vehicle in the state set as described above, data indicating the steering wheel movement state is generated from the position detecting / transmitting unit 10 according to the turning state of the steering wheel and transmitted to the position receiving / display unit 20.

When the steering wheel position data is transmitted as an infrared signal, the position receiving / display unit 20 outputs a signal corresponding thereto and visually displays the position of the wheel through the display window of the LCD display unit 250 or the LED display unit 260. The driver sees this and recognizes the steering condition of the wheel as the steering wheel is moved, and can adjust the steering wheel accordingly to move the vehicle.

In the above description, the transmission and reception of the signal is described as using an infrared signal, but it is obvious that the same purpose can be achieved even by using the radio signal (RF) with the appropriate transmission / reception means (the radio transmitter and the radio receiver).

As described above, according to the present invention, by visually displaying the alignment state of the wheel for the beginner or the inexperienced vehicle to be recognized even when sitting in the driver's seat, there is an advantage that can assist the safe driving during driving or parking. have.
