- the route outline is for the purpose of briefly describing a route for route guidance to the user, and is performed in order to allow the user to recognize in advance a route to be route-guided from this. Then, the user is informed in advance of the route outline by voice and knows in advance the route to the destination, and judges whether or not to travel along the route indicated by the route outline. For example, when the system has been set up, route outline guidance has not been made for the set route once, or the route has been changed, and route outline guidance has been made once for the changed route.
- the system control unit 15 determines that it is necessary to carry out the route outline guide. On the other hand, if route outline guidance has already been executed for the user, the system control unit 15 needs to provide guidance on the route outline, as it will only bother the user even if the outline guidance is repeated many times on the same route. It is judged that there is no If the system control unit 15 determines in step S11 that the route outline guidance is necessary, the process proceeds to the next step S12. On the other hand, if the system control unit 15 determines that the route outline guidance is not necessary, it ends the processing by the subroutine.
- step S 12 the route outline creating unit 25 creates route outline guidance data based on the route data created by the route searching unit 22. The details of the process of creating the route outline guidance data will be described later. Then, the route outline guidance data created in step S12 is sent to the voice processing control unit 23, and the voice processing control unit 23 performs route outline guidance by voice based on the route outline guidance data (step S13). ). Then, the processing by this subroutine is ended.
- the route outline guidance will be described. As described above, the navigation device of the present embodiment does not have a display.
- the route searched on the map displayed on the display is superimposed and presented to the user, or at every point via the route from the departure point to the destination point It is not possible to provide advance route guidance by displaying the name, distance, etc. in detail. Even if they are guided by voice, a vast amount of information will be guided by voice for a long time, and it will be bothersome for the user. Therefore, in the route outline guidance in the navigation device of the present embodiment, a route outline is created rather than guiding the names of route points, road names, distances, right-left turns of intersections, etc. for the searched route. In section 25, the information is voice-guided along the simplified route (route summary) selected.
- information guided by a route outline using voice includes the distance of the route, the estimated travel time of the route, the toll of the route, the name of the route of the route, the intersection where the route turns and the point where the route turns There are landmarks in the vicinity, etc., and the information is included in the map information etc. acquired by the map information acquisition unit 17.
- the voice that guides the distance of the route as the route outline utters "The travel distance is 30 km.”
- the voice that guides the estimated travel time of the route as a route summary utters “The estimated travel time is 1 hour and 20 minutes.”
- the voice that guides the route fee as a route summary utters "The fee is 1250 yen.”
- the voice that guides the route name of the route as a route outline utters "It is a route using National Route 1 and Tomei Expressway.”
- the voice that guides a turning intersection in the route utters “It is a route to turn left at Ginza 1-chome.”
- the voice that guides the landmark near the turning point in the route as the route outline utters "It is a route that turns right in front of Ikebukuro Sunshine 60.”
- information suitable for route outline guidance is selected to capture and simplify features of the set route.
- Selection of information used in this route outline guide it can be considered that information is weighted (prioritized) in advance. For example, in the name of a road, it is weighted in the order of expressway> national road> prefectural road, and in transit points, landmarks such as stations and famous places and famous intersections where road information is often provided are set highly weighted. However, it is only necessary to select some high-weight information from among the searched routes and give voice guidance.
- the information with high weighting is biased to one location, so it is divided into the area near the departure place, the area near the destination, and the middle area sandwiched by both areas.
- the route outline guidance data is created such that the total time of guidance by voice is within the time Tmax. Then, a priority is given to the information to be guided, and the voice information is selected and added according to the priority, and the addition of the voice information is made within the time Tmax.
- the priority given to the information to be guided is according to the distance of the entire set route (the distance from the departure point to the destination; hereinafter referred to as the route distance d) and the distance to the departure point and the destination Change.
- the route distance d the distance from the departure point to the destination
- the distance to the departure point and the destination Change For example, a route where the route distance d from the departure point X to the destination Y1 is less than the distance A (see FIG. 5), and a route distance d from the departure point to the destination Y2 is a distance A or more and less than the distance B (figure 6), and the route set in three routes (see Fig. 7) where the route distance d from the departure point X to the destination Y3 is greater than the distance B (see Fig. 7).
- the destination Y1 is relatively close to the place of departure X.
- the user generally needs the information about the distance of the set route and the name of the intersection in the route and the landmark of the turning point on the route based on the estimated travel time. Therefore, the priority given to the information to guide is set high with respect to the information on the turning intersection in the route and the landmark near the turning point in the route.
- the destination Y3 is relatively far from the departure place X.
- the user generally follows the entire route based on detailed intersection information and information on road names other than the main roads. Needs information that the body can understand. Therefore, the priority given to the information to be guided is set higher for the information on the distance of the route, the estimated travel time of the route, and the road name of the route.
- the priority given to the information to be guided is set higher for the information on the distance of the route, the estimated travel time of the route, and the road name of the route.
- information on intersections that turn near the point of departure will be important information. Therefore, as shown in FIG.
- the entire route is divided into three by distance, and the area near the departure point X is area n, the area near the destination Y 3 is area f, the middle area of area n and area f is area m Set to Then, priority levels to be given to the intersection information belonging to the area n close to the departure point X are set higher than other areas.
- priority levels to be given to the intersection information belonging to the area n close to the departure point X are set higher than other areas.
- FIG. 8 is an example of a priority list created in accordance with the above-described priority assignment rule. As shown in FIG. 8, information is prioritized according to the route distance d and the area in the set route. Note that in the priority table in Figure 8, the lower the number, the higher the priority.
- the route outline creation unit 25 refers to the priority list (see FIG. 8) selected in step S31 above, and extracts information corresponding to priority i to create voice guidance Vi (step S 33). Then, the route outline creation unit 25 calculates the voice time Ti required to guide the voice guidance Vi created in step S33 by voice (step S34).
- the route outline creation unit 25 determines whether the time obtained by adding the voice time Ti to the guidance time T is equal to or longer than the preset maximum voice guidance time Tmax (step S35). That Then, the route outline creation unit 25 advances the process to the next step S36 when it is less than the maximum voice guidance time Tmax, and ends the processing by the subroutine when it is more than the maximum voice guidance time Tmax.
- step S36 the route outline creating unit 25 adds the voice time Ti to the guidance time T to update the guidance time T (step S36). Then, the route outline creation unit 25 adds the voice guidance Vi created in the above step S33 to the route outline guidance data (step S37).
- the route outline creation unit 25 determines whether or not the priority i is lower than or equal to a preset minimum priority imax (step S38). Then, when it is lower than the lowest priority imax, the route outline creation unit 25 adds 1 to the priority i to update the priority i (step S39), and returns to the above step S33 to repeat the processing. On the other hand, when the priority i is larger than the lowest priority imax, the route outline creation unit 25 ends the processing of the subroutine.
- the navigation device of the present embodiment can notify the user of the outline of the route by voice before setting the route and starting the actual route guidance.
- the user can recognize the route safely in advance even in a situation where it is impossible to change the line of sight while driving.
- the route will be understood for the user such as “A route using the high speed road 0000 after the use of the ⁇ ⁇ ⁇ ⁇ XX Highway XX X after using the ⁇ ⁇ ⁇ ⁇ ”. , It is possible to recognize the route to which the user is guided.
- the frequency of roads and places where the user has traveled up to now is stored, and the priority given to the information for the area where the frequency is high may be set low. This reduces the information selected in the route outline guidance for areas that the user is familiar with, and increases the information selected in the route outline guidance for areas where the user is not traveling. As a result, it is possible to provide route outline guidance according to the travel experience area of the user.
- the above priority can be changed by the user.
