Hereinafter, a method of controlling an electronic device and an operation of the electronic device 100 for implementing the same will be described in detail with reference to the accompanying drawings.

Referring to FIG. 3, the controller 180 may set a route to a destination [S100].

For example, a user may input a destination and input a route search command through the user input unit 130. The controller 180 may search for at least one path from the current location obtained by controlling the location information unit 115 or the starting point input by the user using the map stored in the memory 160. Can be.

The controller 180 may set any one path among the at least one searched path according to a user's confirmation or automatically.

4 shows an example of a route 12 set from a current location or origin 10 to a destination 11.

The controller 180 may perform route guidance to the destination based on the set route [S110].

Since the navigation functions provided by the electronic device 100, such as the above-described destination input, route search, route setting, and route guidance, are well known in the art, detailed descriptions thereof will be omitted.

The controller 180 may acquire the traffic light related information existing on the set path 12 [S120].

The traffic light related information includes time information related to a signal change of at least one traffic light existing on the set path 12 and position information of the at least one traffic light, and exists on the set path 12. It may be information related to a traffic light installed at an intersection or installed at the intersection and the crosswalk.

FIG. 5 shows an example of the traffic lights 20a and 20b provided at the crosswalk, and FIG. 6 shows an example of the traffic lights 21a, 21b, 21c and 21d provided at the intersection.

For example, the traffic light related information may be a signal change period, a signal change time, a specific signal (for example, the traffic light 20a or 20b installed in a specific pedestrian crossing existing on the set path 12). Time information related to a signal change of the traffic lights 20a and 20b, such as a holding time of a green signal or a red signal).

When the vehicle equipped with the electronic device 100 moves along the set route 10, a traffic light installed at a crosswalk or intersection existing on the set route 10 is a stop signal (for example, a red signal). If the vehicle reaches the pedestrian crossing or intersection when it is not a passing signal (e.g. a green signal or a left turn signal), the vehicle does not need to stop to wait for a signal, preventing idling and speeding at departure. It is automatically prevented to improve fuel efficiency.

The traffic light related information may be stored in the memory 160 in advance. In this case, the traffic light related information may be stored in association with the map as information related to the map stored in the memory 160.

The controller 180 may update the traffic light related information through communication with the server 200. In this case, the controller 180 may update the entire map related information including the traffic light related information or communicate only the traffic light related information through communication with the server 20.

When the traffic light related information is stored in the memory 160, the traffic light related information may be stored for the entire map stored in the memory 160.

When the specific path 12 is set by the step S100, the controller 180 may call the traffic light related information corresponding to the set path 121 from the memory 160.

The traffic light related information corresponding to the set path 121 means information related to at least one traffic light existing on the set path 121.

Meanwhile, after the path 12 is set, the controller 180 requests the server 200 for the traffic light related information corresponding to the set path 12 and requests the traffic light from the server 200. Information can be received.

In this case, the controller 180 may control the mobile communication module 112, the wireless internet module 113, or the short range communication module 114 to communicate with the server 200.

Here, the controller 180 may receive the traffic light related information corresponding to the entire set path 12 from the server 200. For example, when the number of traffic lights installed in the set path 12 is 100, the traffic light related information may be received for all 100 at once.

In addition, the controller 180 may sequentially receive the traffic light related information corresponding to the predetermined number of traffic lights or a predetermined section from the server 200 according to a change in the current position of the electronic device 100. .

FIG. 7 is a diagram for describing a case where the traffic light related information corresponding to the predetermined number of traffic lights is received.

For example, referring to FIG. 7, it is assumed that a total of 13 traffic lights are installed in the path 12, and the predetermined number of traffic lights is five.

The controller 180 may perform a route guidance based on the route 12, at a position at which the movement starts at the departure point 10 or at a position P1 at which the route guidance based on the route 12 starts. In addition, the traffic light-related information for the first traffic light group including the first five traffic lights 30 may be received from the server 200.

And, while moving along the path 12, the control unit 180, at the position (P2) before or immediately after entering the section in which the second group of traffic lights including the next five traffic lights 31 is installed The traffic light related information on the second traffic light group 31 may be received from the server 200.

The controller 180 is associated with the traffic lights for the third traffic light group 32 at a position P3 before or immediately after entering a section in which the third traffic light group including the last three traffic lights 32 is installed. Information may be received from the server 200.

8 is a diagram for describing a case where the traffic light related information corresponding to a predetermined section is received.

For example, referring to FIG. 8, the controller 180 performs a route guidance based on the route 12, and a position starting from the departure point 10 or a route based on the route 12. At the starting point P5 of the guidance, the traffic light related information on at least one traffic light installed in the first section 34 based on the distance may be received from the server 200.

In addition, while moving along the path 12, the controller 180 may move to the second section 35 at a position P6 before or immediately after entering the second section 35 based on a distance. The traffic light related information may be received from the server 200.

In addition, the controller 180 may control the third section 36 and the fourth section 37 at positions P7 and P8 before or immediately after entering the third section 36 and the fourth section 37, respectively. ) May be received from the server 200 for the traffic light-related information for each.

The predetermined number of traffic lights or the predetermined section may vary according to the total length of the path 12 and the number of traffic lights installed in the path 12.

For example, the predetermined number of traffic lights may be 10 when the total length of the path 12 is within 3 km, and 30 when the total length of the path 12 is 3 to 5 km.

Also, for example, the predetermined section may be 1 km when the total length of the path 12 is within 5 km, and 2 km when the total length of the path 12 is 5 to 10 km.

As described above, the step S120 may be performed before the controller 180 performs the route guidance based on the set route 12 or may be performed while the route guidance is performed.

The controller 180 may provide speed information for preventing signal waiting stops based on the obtained traffic light related information [S130].

Here, the controller 180 may determine the speed information for driving without waiting for a signal at the next traffic light in consideration of the current position of the electronic device 100, the remaining distance to the next traffic light, and the signal change time of the next traffic light. Can provide.

9 is a diagram for explaining a method of calculating speed information provided according to an embodiment of the present invention.

The controller 180 may use a current position P10 of the electronic device 100 and a position of a next traffic light 23a located at a position P11 closest to the current position on the path 12. The remaining distance from the current position to the next traffic light 23a can be calculated.

The current location P10 of the electronic device 100 may be obtained by controlling the location information unit 115. In addition, the position P11 of the next traffic light 23a is included in the above-mentioned traffic light related information.

For example, referring to FIG. 9, when the current location of the vehicle 300 on which the electronic device 100 is mounted is P10 and the location of the next traffic light 23a is P11, the current location The remaining distance d from the position P1 to the next traffic light can be calculated.

Here, the exact physical position P12 of the next traffic light 23a and the conceptual position P11 of the next traffic light 23a used to calculate the speed information are slightly as shown in FIG. 9. There may be differences.

When the vehicle 300 is located at the conceptual position P11 rather than the physical position P12 of the next traffic light 23a, the signal indicated by the next traffic light 23a is a stop signal (for example, a red signal). This is because it must be a driving signal (eg a green signal).

In addition, the traffic light related information includes time information related to the signal change of the next traffic light 23a, as described above. Fig. 10 shows an example of time information associated with the signal change of the next traffic light 23a.

In the example of FIGS. 9 and 10, in order for the vehicle 300 equipped with the electronic device 100 to pass through an intersection without stopping for signal waiting at the next traffic light 23a, the vehicle 300 is The first time interval 50 corresponding to 11:30 to 11:32 or the second time interval 51 corresponding to 11:38 to 11:40 should be located at the point P11 shown in FIG. 9.

The controller 180 uses the aforementioned various information (distance and time) so that the vehicle 300 on which the electronic device 100 is mounted is the first time interval 50 or the second time interval. At 51, speed information that can be located at the P11 point can be calculated. Divide the distance by time to get the velocity.

Here, in calculating the speed information, the controller 180 may consider a speed limit (for example, 60 km / hour) for a section currently moving.

That is, the controller 180 is the speed at which the vehicle 300 may be located at the point P11 at a point in time when the vehicle 300 is included in the first time interval 50 or the second time interval 51. The speed can be calculated without departing from the speed.

For example, when the speed limit is 60 km / hour, the vehicle 300 travels at 70 km / hour in order to be located at the P11 point in the first time section 50 of the time information shown in FIG. 10. If the vehicle 300 has to travel at 55 km / hour in order to be located at the P11 point in the second time interval 51, the controller 180 may provide 55 km / hour to the user. You can decide by speed.

Here, 55 km / hour calculated may mean an average speed of a speed section for positioning the vehicle 300 at the point P11 in the second time section 51.

In addition, the controller 180 may provide a maximum speed and a minimum speed for the vehicle 300 to be located at the P11 point in the second time interval 51.

For example, at 11:38, the speed for the vehicle 300 to be located at the P11 point is 57 km / hour, and at 11:40 the speed for the vehicle 300 to be located at the P11 point is 53 km. In the case of / hour, the controller 180 may provide 57km / hour at the highest speed and 53km / hour at the lowest speed.

The controller 180 may provide the speed information visually and / or audibly in the step S130.

For example, the controller 180 may display the speed information on the display unit 151 and output the speed information as a sound through the sound output unit 152.

11 and 12 illustrate examples in which step S130 is performed.

For example, referring to FIG. 11, in the above-described example, the controller 180 supplies speed information 61 and 57 km / hour necessary for driving without stopping for signal waiting at the next traffic light 23a of the current section. The speed limit information 60 and 60 km / hour may be displayed on the display unit 151.

Also, for example, referring to FIG. 12, the controller 180 does not display the average speed information 61 shown in FIG. 11, but the minimum speed information 63 necessary to stop and drive at the next traffic light 23a. , 53 km / hour) and maximum speed information 64, 57 km / hour may be displayed on the display unit 151.

Meanwhile, the controller 180 may update and provide the speed information according to a change in a current time or a change in a current position of the electronic device 100.
