BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a service providing technique of vehicle navigation. More particularly, the present invention provides an optimal driving route in consideration of a signal waiting time by a traffic light located on a driving route when executing a navigation mode. The present invention relates to a driving route service method and apparatus for vehicle navigation, and an additional service providing method and apparatus suitable for servicing traffic light information present on the vehicle.

As is well known, a navigation device is mounted on (or mounted on) a moving object, such as a vehicle, and has its current coordinate values from a global positioning system (GPS) satellite in the air via its internal or external GPS receiver.

That is, the navigation device receives radio waves representing latitude, longitude, and altitude from a plurality of satellites belonging to the GPS, calculates the current position (coordinate value) of the moving object (vehicle, etc.), and maps corresponding to the calculated current position. Information is extracted from the map DB and provided visually and audibly through monitors and speakers.

At this time, the driving route screen provided through the monitor displays various information such as the driving route and direction to the destination, the current vehicle speed of the vehicle, the traffic lights at each intersection, the remaining distance to the destination, the estimated time to the destination, and the like.

Here, the traffic lights optionally include direction indicators such as, for example, straight, stop, left turn, right turn, etc., where the direction indications are expressed as colors (blue, yellow, red) and / or arrows, conventionally traveling Only the presence of a traffic light is displayed on the route screen.

Accordingly, the drivers drive the vehicle toward the destination while viewing the various information displayed on the driving route screen.

In general, urban roads with many resident populations and many different buildings (especially complex roads in urban centers with tangled shapes) are equipped with numerous traffic lights depending on the situation of each road. These traffic light systems guarantee safe driving and safe walking.

On the other hand, traffic lights installed on complex roads in the city for safe driving and safe walking of vehicles and people cause frequent stopping of the vehicle for driving to the destination, which leads to unnecessary excessive travel time. It is a reality.

The present invention calculates the signal waiting time according to the use of traffic lights for each of the candidate paths to the destination when providing a navigation service, and calculates the total signal waiting for each candidate path calculated by weighting them according to the use of traffic lights and the type of traffic. By determining the optimal driving route by comparing the time and providing the navigation service with the determined optimal driving route, it is possible to suppress the increase in the driving time due to the signal waiting time caused by the traffic light, and thereby the user satisfaction of the navigation service.

In this case, the adjacent road means a road that the vehicle can detour on the driving path, and each traffic light symbol displays the remaining holding time of the current color expressed in the form of being subtracted by the second over time (for example, in the form of a pop-up menu). In addition, each traffic light symbol may be displayed in a flashing form for improved identification.

Next, the GPS reception block 104 may include, for example, a GPS reception antenna, a satellite signal processor, and the like, and the current of the vehicle obtained by processing satellite signals received at predetermined time intervals from remote GPS satellites, not shown. The coordinate values are transmitted to the vehicle speed calculation block 106 and the control block 110, respectively. Here, the GPS reception block 104 selectively receives a function such as receiving and transmitting the traffic light information to the control block 110 when the traffic light information is transmitted via the GPS satellite 206 as shown in FIG. 2.

In this case, the traffic light information transmitted from the information receiving block 108 may be stored in the memory block 112.

In addition, the route search block 114 searches for the map DB 118 based on the current coordinate values of the vehicle transmitted from the control block 110 for the service of the optimum driving route provided according to the present invention, and then reaches the destination. Search a plurality of candidate paths, extract travel time (time required) information and traffic light information (traffic light number, traffic light usage, road width, traffic type) of each searched candidate paths, and search for candidate paths and travel time Information and traffic light information is provided to the path determination block 116. Here, the use of a traffic light indicates a straight lane traffic light, an intersection traffic light, and the like, and the traffic mode indicates a straight, left turn, right turn, and the like.

The signal wait time (signal wait time for each candidate path) for the traffic lights classified according to the purpose is calculated, and the calculated signal wait time is calculated. The total signal wait time for each candidate path is calculated by weighting according to the traffic type (for example, straight, left turn, right turn, etc.), and among the candidate paths according to the driving time and the calculated total signal wait time. The candidate path that takes the least time is determined as the optimal driving path. That is, the candidate path having the smallest sum of the driving time and the total signal waiting time is determined as the optimum driving path, and the optimum driving path determined as described above is provided to the path search block 114.

The optimal detour route is determined in the range of the driving route and the adjacent road, for example, the driving time is searched for a path that is relatively shorter than the driving time of the corresponding driving path, or the number of pauses by a traffic light is determined in the corresponding driving path. It can be searched by a path relatively smaller than the number of pauses by the traffic light.

Next, the graphics processing block 122 constructs or bypasses a map information screen, such as an optimal driving route screen, through graphic processing on the driving route data delivered from the route searching block 114 when the navigation device executes the navigation mode. By constructing the update driving route screen through the graphic processing on the detour route data including the optimal detour route to which the traffic light information transmitted from the route search block 120 is mapped, the optimal driving route screen or the update driving route configured as described above is configured. The screen is transferred to a monitor (e.g., LCD panel, etc.) not shown and displayed (displayed).

Meanwhile, in the embodiment of the present invention, the navigation device includes an information receiving block for receiving traffic light information transmitted through a wireless network, but the present invention is not necessarily limited thereto, and the traffic light information using GPS satellites is not limited thereto. Of course, when sending the information to the navigation device it is not necessary to include such information receiving block in the navigation device.

That is, in the traffic information service system, the traffic control center 204 transmits the traffic light information to each navigation side using the GPS satellite 206 in order to realize the additional service provided in accordance with the present invention.

3 is a conceptual block diagram of a traffic information service system showing another example of providing an additional service to an apparatus for providing an additional service for vehicle navigation according to the present invention, wherein the traffic light controller includes a plurality of traffic light controllers 302/1-302 / n. Group 302, traffic control center 304, wireless network management server 306, navigation group 308 of multiple navigations 308/1-308 / n, and the like.

Referring to FIG. 3, each of the traffic light controllers 302/1-302 / n and the traffic control center 304 in the traffic light controller group 302 are substantially the same as the corresponding components shown in FIG. 2. Do. That is, except that the traffic control center 304 transmits the traffic light information to the radio network management server 306 to use the radio network instead of the GPS satellites, and the other functions are substantially the same.

Therefore, in order to avoid unnecessary duplication of description for the sake of brevity, the detailed description thereof will be omitted.

Next, the wireless network management server 306 performs a function similar to, for example, a base station controller for wireless communication, for example, a wireless network control / management function, and the like, and a navigation device mounted on a navigation (for example, a vehicle, etc.) via the wireless network. And the like for additional services, such as controlling traffic light information received from the traffic control center 304 to wirelessly transmit through the wireless network.

That is, in the traffic information service system, the traffic control center 304 transmits the traffic light information to each navigation side using the radio network management server 306 and the radio network in order to realize the additional service provided according to the present invention. .

Next, a series of processes for providing an optimal driving route service and an additional service according to the present invention using the driving route and the additional service providing apparatus for a vehicle navigation having the above-described configuration will be described.

4 is a flowchart illustrating a main process of providing a service in an optimal driving route in consideration of a waiting time by a traffic light according to the present invention.

Referring to FIG. 4, when a user (driver) inputs a destination to which he / she wants to go by operating an operation panel or the like while the navigation device mounted on the vehicle (or mounted) performs the standby mode (step 402), the control block ( In operation 110, the route search block 114 commands the drawing of the corresponding driving route setting menu screen, and in response, the route searching block 114 draws the driving route setting menu screen data from the map DB 118 to display the graphic. Transfer to process block 122, and as a result, a driving route setting menu screen including, for example, an optimum driving route selection item, a shortest route selection item, a highway priority route selection item, a safety driving path selection item, and the like is displayed (display (Step 404). Here, the optimum driving route selection item is a selection item for receiving the optimum driving route service considering the signal waiting time by the traffic light on the driving route provided according to the present invention.

Accordingly, the user (driver) can select the optimal driving route service by clicking (operation) on the selected items on the driving route setting menu screen (step 404). When it is determined that the selection is made, the control block 110 generates a command signal for the execution of the corresponding optimum driving path service and transmits the command signal to the path search block 114 together with the current coordinate value information of the vehicle.

In response, the route search block 114 searches the map DB 118 based on the current coordinate values of the vehicle transmitted from the control block 110 to search for a plurality of candidate routes to the destination, and each of the found angles. It extracts the driving time (time required) information of the candidate routes and the traffic light information (the number of traffic lights, the purpose of the traffic lights, the road width, and the traffic type). It is passed to 116 (step 406). Here, the use of a traffic light indicates a straight lane traffic light, an intersection traffic light, and the like, and the traffic mode indicates a straight, left turn, right turn, and the like.

Next, the path determining block 116 calculates the driving time (ie, time required) for each of the searched candidate paths, extracts the number of traffic lights located on each candidate path (step 408), The extracted traffic lights are classified into their uses (e.g., straight lane traffic lights, intersection traffic lights, etc.) and the signal waiting time (signal waiting time for each candidate path) for the traffic lights divided according to the use and the road width is calculated (step). 410). That is, assuming that five candidate paths have been searched, the path determination block 116 calculates driving time and signal waiting time for each of the five candidate paths.

As an example, in the case of a straight lane traffic light, which is a pedestrian traffic light, a signal waiting time for each traffic light is calculated, for example, "road width (meter) + 7 seconds", etc., and in the case of an intersection traffic light, the road width and a traffic type (for example, going straight). , Left turn, right turn), for example, 2-5 minutes, etc. For example, assuming a 30-meter crosswalk with a straight lane traffic light, "30 + 7 seconds = 37 seconds", etc. It can be calculated as.

Again, the path determination block 116 assigns a weight to each signal waiting time calculated for each candidate path according to the traffic type (eg, going straight, left turning, right turning, etc.) (step 412).

For example, in the case of the signal waiting time summed up for all the straight lane traffic lights, in consideration of the selective waiting, for example, a weight (A) of 10% to 20% is given, and the traffic pattern for all intersection traffic lights. According to the straight, left turn, right turn, etc. After going straight, for example, the weight (B), such as 20%-30%, for the left turn, for example, the weight (C), such as 50%, and the right turn For example, weights D such as 10% -20% may be applied.

Next, the path determination block 116 calculates the total signal waiting time for each candidate path based on the weights assigned according to the traffic pattern (step 414), and calculates each of the calculated total signal waiting time and each of the candidate paths. The running time is summed, and the summation times are compared with each other to determine a candidate path having the relatively smallest summation time (ie, the total travel time) as the optimum driving path (step 416). Thereafter, the optimal driving route information thus determined is transferred to the route search block 114. Here, each total signal waiting time for each candidate path may be calculated, for example, as A + B + C + D mentioned above.

In response, the route search block 114 searches the map DB 118 to extract map information for the optimal driving route, and construct map information data (optimal driving route data) based on the extracted map information. To the graphics processing block 122. As a result, the graphics processing block 122 generates an optimal driving route screen through graphic processing of the map information data and transmits it to the monitor side, whereby the optimum traveling route screen is displayed on the monitor. The navigation mode is then executed (step 418).

Therefore, the driver can be provided with the service for the optimum driving route determined (selected) in consideration of the signal waiting time of each traffic light located on the driving route.

5 is a flowchart illustrating a main process of providing traffic light information as an additional service according to the present invention.

Referring to FIG. 5, while a navigation device mounted on (or mounted on) a vehicle performs a standby mode, a user (driver) operates an operation panel or the like to input a destination to which he / she wants to go, and a driving route (for example, optimal driving). Route), the control block 110 generates a command, that is, a map information providing instruction, and transmits the execution control of the corresponding navigation mode to the route search block 114.

As a result, the route search block 114 constructs map information data for the driving route screen based on the map information drawn from the map DB 118, and transfers the map information data to the graphics processing block 120, and in response thereto, the graphics processing block. By passing the driving route screen data configured through the graphic process to the monitor side, the navigation mode in which the driving route screen (or the optimal traveling route screen) of the region where the vehicle is currently located is displayed on the monitor is executed (step 502). ).

Next, the user (or driver) may select (touch or button operation) the detour route navigation including display of traffic light information through the user interface, and the check in step 504 selects the detour route navigation by the user. If it is determined that, the control block 110 transfers the current vehicle speed information of the vehicle provided from the vehicle speed calculation block 106 and the traffic light information provided from the information receiving block 108 to the bypass path search block 120 (step 506). ).

Subsequently, the detour path search block 120 searches for the map DB 118 using the current vehicle speed information and the traffic light information (colored sustain time information of the color of each traffic light) provided from the control block 110, thereby adjoining the driving route. It is checked whether there is an optimal route on the road (step 510). Here, the optimum detour route is determined in the range of the driving route and the adjacent road, for example, the driving time is a path that is relatively shorter than the driving time of the corresponding driving path or the number of pauses by the traffic light is the traffic light in the corresponding driving path. It may be a path relatively smaller than the number of pauses.

As a result of the check in the step 510, if there is no optimal route on the road adjacent to the driving route, the detour route search block 120 generates a corresponding absence guidance message and transmits it to the graphic processing block 122, In response, the graphics processing block 122 processes the absence guidance message in OSD form and forwards it to a monitor (not shown) (step 512), whereby the user will visually recognize that there is no optimal bypass path.

On the other hand, when it is determined in the step 510 that the optimum route exists on the road adjacent to the driving route, the detour route search block 120 maintains the remaining time of the current color for each traffic light on the optimal detour route. (Step 514), update bypass path data including the optimal priority path data (i.e., bypass path data including the optimal bypass path to which traffic light information is mapped) is generated and transmitted to the graphic processing block 122 ( Step 516). Here, the optimal detour path data includes traffic light symbols represented at the position of each traffic light, for example, in the form of flashing with the traffic light color representation, and the remaining holding time of the current color displayed around each traffic light symbol is passed over time. According to the sub-second subtraction can be displayed in the form of a pop-up menu.

Subsequently, the graphic processing block 122 configures the update driving route screen through graphic processing on the detour route data including the optimal detour route to which the traffic light information is mapped, and transmits the updated driving route screen to the monitor, not shown, and as a result, the optimal detour on the monitor. The update travel route screen including the route is displayed (step 518).

Therefore, the user can selectively determine the change of the vehicle driving route while viewing the optimum detour route displayed through the monitor of the navigation device.

6 is an exemplary path diagram illustrating a process of finding an optimal bypass path in consideration of traffic light information according to the present invention.

Referring to FIG. 6, the portion indicated by the arrow is a driving route 602 with three traffic lights CP11, CP12, CP13, and two adjacent roads (bypassable adjacent roads) 604 and 606 on the driving route. In addition, assuming that one adjacent road 504 is the optimum detour path, the optimum detour path is displayed on the update travel path screen as an arrow 608 of a different color or an arrow of a different display form.

That is, the optimum detour route having the form of turning right at traffic light CP11 → turning left at traffic light CP21 → straight at traffic light CP22 → straight at traffic light CP23 is displayed on the update travel path screen. This may be an optimal bypass route that can be effectively selected when the vehicle being driven receives a right turn signal at the first traffic light CP11 on the travel route. In Fig. 5, reference numeral 21-1 denotes a popup menu for displaying the remaining holding time of the current color of the traffic light CP21, and reference numeral 22-1 denotes a popup menu for displaying the remaining holding time of the current color of the traffic light CP22. The reference numeral 23-1 denotes a pop-up menu for displaying the remaining holding time of the current color of the traffic light CP23.

Accordingly, the driver may be able to drive (driving) the vehicle by selecting the optimal bypass route from CP11 to CP21 to 22 to CP23 as his driving route.
