The present invention relates to a navigation device having a direction checking function. More particularly, the present invention relates to a driving path based on a direction indicator to determine whether the driving path provided by the navigation device matches the path currently being driven by the driver. The present invention relates to a navigation device having a direction checking function for reducing the risk of a traffic accident due to a drastic lane change and preventing time and economic waste caused by a departure of a driving route.

The navigation device, for example, calculates a location information signal received from a GPS satellite to grasp the current location of the vehicle or the user in real time, and connects it with a database of pre-established map information, traffic information, etc. on a database corresponding to the current location. The device converts the data into image / audio information and displays the optimal route to the destination, so that the user can easily grasp the route to the destination.

Meanwhile, in order to accurately calculate the current position of the vehicle in the navigation device, a GPS device is mainly required. In the case of using such a GPS device, information about a vehicle state such as a current speed, time, and location information of a vehicle may be acquired. A conventional navigation device may provide navigation to a user based on vehicle information obtained by receiving such a GPS signal. Information is provided.

GPS signals may be received from three or more satellites close to the current location of the vehicle, of which 24 GPS satellites are located around the earth at a frequency of 6 GHz as is known. For example, GPS signals received from three satellites may be received by a car navigation device at a time difference, and thus the current position is calculated using the time difference.

In addition, in the navigation device having a direction confirmation function according to the present invention, the predetermined message of the message output unit may be a predetermined voice alert message.

Hereinafter, with reference to the accompanying drawings, a navigation device having a direction confirmation function of the present invention will be described in more detail.

2 is an exemplary block diagram of a navigation device having a direction checking function according to the present invention.

As shown, the navigation device having a direction confirmation function according to the present invention includes a driving route providing unit 110, a direction indicator light confirmation unit 120, and a message output unit 130.

The driving route providing unit 110 provides a driving route message corresponding to the destination. That is, as described with reference to FIG. 1, the driving route generated by the navigation apparatus is compared with the current position of the vehicle equipped with the navigation apparatus having the direction checking function according to the present invention, and the driving route message generated based on this. Is output in the form of voice, for example, to the driver.

The direction indicator confirming unit 120 checks whether the direction indicator of the vehicle equipped with the navigation device having the direction checking function according to the present invention operates in response to the driving route message provided by the driving route providing unit 110.

This confirmation can be implemented in various forms.

For example, when the turn signal is activated, a continuous "tick" tone is generated and output. The turn signal confirming unit 120 may detect an operation sound of the turn signal to determine whether the turn signal of the vehicle operates in response to the driving route message provided by the driving route providing unit 110.

In this case, the turn signal confirming unit 120 may implement an audio input configuration such as a microphone for audio input and a comparison configuration that determines whether the audio input matches the sound of the turn signal through an electronic circuit.

However, this configuration has a disadvantage in that it is difficult to use when the noise in the car is severe. That is, since the noise must be filtered and the operating sound of the turn signal must be sensed based on the noise, manufacturing cost increases.

Therefore, it is possible to configure the detection of the operation of the turn signal in another way.

For example, an automobile may include an electronic control unit (ECU), and an operation state of an electronic device mounted in a plurality of vehicles may be checked through the electronic control unit.

In the case of using the electronic control unit, the turn signal confirming unit 120 according to the present invention may be connected to the electronic control unit of the vehicle equipped with the navigation apparatus according to the present invention through wired or wireless communication. Through this configuration, the turn signal confirming unit 120 may check the operation state of the turn signal of the vehicle, and thus, may determine whether the turn signal of the vehicle is operated in response to the travel route message provided by the travel route providing unit 110. .

Alternatively, a configuration using a sensor network node may be used. That is, since it may be complicated to connect with the electronic control unit, a sensor network node for detecting an operation state is disposed on the direction indicator, and a sensor network node corresponding to the direction indicator confirmation unit 120 according to the present invention is also disposed.

 In this case, the sensor network node disposed in the turn signal and the sensor network node corresponding to the turn signal confirming unit 120 may also communicate with each other to check an operation state of the turn signal. Thus, the turn signal of the vehicle may provide a driving route providing unit ( It may be checked whether the operation is performed in response to the driving route message provided by 110.

The message output unit 130 outputs a predetermined message to correct the direction indicator when the direction indicator does not operate in response to the driving route message.

Such a message may be configured in various forms.

For example, the message output unit 130 may output a driving route message corresponding to a destination provided by the driving route providing unit 110 by increasing the quantity. That is, the driving route message may have a low volume, which may not attract the driver's attention and may not recognize the direction indication. Therefore, the message output unit 130 may output the driving route message that is the same as the driving route message but the volume of the message is increased.

Alternatively, the message output unit 130 may draw attention of the driver by, for example, blinking the warning message through the lighting device. The lighting device may be a device such as an LED provided in the navigation device, or may be a display device connected to the navigation device.

Alternatively, the message output unit 130 may be configured to output a pre-specified voice warning message, for example, a message such as "not currently traveling along the driving route."

Through such a configuration, the navigation device having a direction checking function according to the present invention prevents the driver from driving the vehicle so as to be suitable for the driving route and the time and economic waste caused by driving on a route other than the optimal route. can do.

Although the configuration of the present invention has been described in detail, it is only for illustrating the present invention, and the protection scope of the present invention is not limited thereto, and the protection scope of the present invention is defined through the description of the claims.

As described above, according to the present invention, a sudden lane change is determined based on the direction indicator to determine whether the driving route provided by the navigation device and the route currently being driven by the driver are checked again. This reduces the risk of traffic accidents and prevents time and economic waste caused by deviations from the driving route.
