2. Description of the Related Art In general, various devices are installed in a vehicle for the convenience of a driver, and among the convenience devices, a navigation system serves to safely guide the driver to a destination.

When the driver sets the destination he wants to go to on the navigation terminal, the navigation terminal provides visual and voice guidance for directions according to straight, left, and right turns, and the driver accepts them and drives to the destination.

Here, the vibration form may be a form in which one cycle is set to be long or a form in which one cycle is set to a short period. Vibration intensity can be set through numerical values or steps as vibration intensity.

When the vibration pattern to be generated through the steering wheel 1 is set through the vibration setting unit 10 , the main control unit 20 stores it in the internal memory.

In a state in which the navigation device 2 is linked, the navigation device 2 performs route guidance according to the selection of a destination or provides map information based on the current location, similarly to general navigation.

When the position of the speed violation camera that controls speed is detected while providing route guidance or map information, vibration generation information is transmitted to the main control unit 20 . Here, the vibration generation information may be a speed camera detection signal. In this case, the vibration generation information may include distance information. Distance information is information that can be generally obtained from navigation.

When vibration generation information and distance information are generated from the navigation device 2 while the vehicle is being driven, the main control unit (MCU) 20 searches an internal memory and extracts a vibration pattern set by the driver.

Then, based on the extracted vibration pattern, an initial vibration generation control signal is output and transmitted to the vibration motor driving unit 30 . Here, the initial vibration generation control signal is a vibration generation control signal according to the position detection distance of the speed camera preset in the navigation system.

The vibration motor driving unit 30 drives the vibration motor 40 mounted at a predetermined position of the steering wheel 1 according to the vibration generation control signal output from the main control unit 20 to apply vibration to the steering wheel 1 . Occurs.

Vibration intensity can be set through numerical values or steps as vibration intensity.

When the vibration pattern to be generated through the steering wheel 1 is set through the vibration setting unit 10 , the main control unit 20 stores the vibration pattern changed in step S104 in the internal memory. If the driver does not request to change the vibration pattern, the previously set vibration pattern is maintained as in step S103.

Meanwhile, as another feature of the present invention, the main control unit 20 automatically varies the intensity of vibration generated by using the distance information transmitted from the navigation device 2 . In other words, the closer the distance to the speed camera is, the higher the vibration intensity is, so that the driver does not get caught in a speed violation.

Here, the vibration intensity variable may be implemented in various ways.

For example, as shown in FIG. 2 , the vibration motor driving unit 30 operates according to the vibration generation control signal output from the main control unit 20 , the on/off mode of driving the vibration motor, and the frequency (Frequency; Low, High). Intensity, duration (Short, Long), waveform shape (Wave Shape; Smooth, Sharp), amplitude (Amplitude; Weak, Strong), frequency, waveform shape or amplitude is combined using a combination waveform The vibration intensity is adjusted by varying the driving voltage of the motor 40 .

Thereafter, the navigation unit 2 ends the output of the vibration generation information when out of the detection range of the surveillance camera as in step S110, and the main control unit 20 controls the steering wheel 1 if the vibration generation information is not received in step S111. ) to turn off the vibration generation.

As described above, the present invention generates vibrations in the steering wheel when the position of the speeding camera is detected through interlocking with the navigation system to prevent the driver from being caught in the speeding regulation. In addition, it allows the driver to freely set the intensity or form of vibration generated through the steering wheel. In addition, by automatically changing the vibration intensity of the steering wheel to a higher level using distance information from the speed camera, the driver's cognitive performance of speed control may be increased, thereby reducing the risk of the driver being caught in the speed control control.
