  The arrival time calculation unit 1148 obtains the travel distance and the walk distance based on the input travel route and the walk route, obtains the travel time and the walk time based on the travel distance and the walk distance, and arrives at the destination. Calculate the estimated arrival time. The arrival time calculation unit 1148 inputs the estimated arrival time calculated together with the temporary destination information to the search route combination unit 1152.

  The alerting item calculation unit 1150 calculates the value of the alerting item as the input health promotion index based on the information indicating the walking route by walking from the temporary destination to the destination input by the route search unit 1144. And input to the search path combining unit 1152 together with the alert item. For example, when the alerting item is the number of steps, the walking distance is calculated from the input walking route, and the number of steps is calculated based on the walking distance. Further, for example, when the attention calling item is walking time, the walking distance is calculated from the input walking route, and the walking time is calculated based on the walking distance. For example, when the alerting item is a walking distance, the walking distance is calculated from the input walking route. For example, when the alerting item is calorie consumption, the walking distance is calculated from the input walking route, and the calorie consumption is calculated based on the walking distance. Here, when the walking distance is calculated from the walking route, the walking distance may be obtained from the actual walking route based on the accuracy of the map data included in the map database 118 described later, The walking distance may be obtained.

  The search route combining unit 1152 relates to the destination information and arrival time, the temporary destination information and the destination arrival time input by the arrival time calculation unit 1148 and the alert item calculation unit 1150, and the alert item and the alert item. Based on the value in each route, the estimated arrival time is associated with the alert item for each destination including the temporary destination. These associated data are input to the display unit 106 as display data. The display unit 106 displays the input display data.

  As an example, a case where a parking lot is selected as a temporary destination and calorie consumption and a parking lot fee are selected as alert items will be described with reference to FIG.

  The destination setting unit 1142 sets the destination input by the user in the map information stored in the map database 118. In addition, the destination setting unit 1142 also acquires information on the parking fee of the parking lot at the set destination.

  The temporary destination setting unit 1146, based on the destination set by the user, from the map information stored in the map database 118, places that can be moved to the destination on foot, such as parking lots A, B, and C, Set as a temporary destination. The temporary destination setting unit 1146 also acquires information on the parking fee for the set parking lot.

  The route search unit 1144, based on the destination information input by the destination setting unit 1142, provides a route from the vehicle position (start point) to the destination (user destination) and a temporary destination from the vehicle position (start point). Routes to the ground (suggested parking lots A, B and C) and routes from each temporary destination to the destination (user destination), specifically, routes from the parking lots A, B and C to the destination And search (search). The route from each temporary destination to the destination may be searched on condition that the time to arrival is the shortest, or may be searched on condition that the distance to arrival is the shortest. Also good.

  The arrival time calculation unit 1148 travels when the route from the vehicle position to the destination is traveled by an automobile and the route from the vehicle position to each temporary destination, specifically, the parking lots A, B, and C. The travel time when traveling by the vehicle and the travel time when walking along the route from each temporary destination to the destination, and the travel time when traveling by vehicle from the vehicle position to each temporary destination The total travel time when walking along the route from each temporary destination to the destination is summed, the arrival time when traveling by car from the vehicle position to the destination, and each temporary destination from the vehicle position. The vehicle travels on the route to the destination, and obtains the arrival time (expected arrival time) when walking along the route from each temporary destination to the destination.

  For example, the arrival time of 55 minutes is obtained from the travel time when the vehicle travels from the vehicle position to the destination. In addition, a travel time of 50 minutes when traveling by car from the vehicle position to the parking lot A and a walking time of 5 minutes when walking along the route from the parking lot A to the destination are obtained. The walking time is added up to obtain an arrival time of 55 minutes. Further, a travel time of 60 minutes when traveling by car from the vehicle position to the parking lot B and a walking time of 20 minutes when walking along the route from the parking lot B to the destination are obtained. The walking time is added up to obtain an arrival time of 80 minutes. In addition, a travel time of 65 minutes when traveling on a route from the vehicle position to the parking lot C by a car and a walking time of 40 minutes when walking along a route from the parking lot C to the destination are obtained, By adding the walking time, an arrival time of 105 minutes is obtained. Here, the arrival time is the time taken to arrive at the destination from the vehicle position.

  The arrival time calculation unit 1148 obtains an estimated arrival time when each route is selected based on the current time and the arrival time. For example, when the current time is 9:15, the estimated arrival time of 10:10 when the vehicle travels from the vehicle position to the destination by the automobile is obtained. Further, the estimated arrival time of 10:10 when the vehicle travels from the vehicle position to the parking lot A and walks along the route from the parking lot A to the destination is obtained. Further, the estimated arrival time of 10:35 is obtained when the vehicle travels from the vehicle position to the parking lot B by a car and walks the route from the parking lot B to the destination. Further, the estimated arrival time of 11:00 when the vehicle travels from the vehicle position to the parking lot C by a car and walks the route from the parking lot C to the destination is obtained.

  The alert item calculation unit 1150 obtains a value related to the alert item based on the input walking route from the temporary destination to the destination. For example, when calorie consumption and parking fee are selected as alert items, calorie consumed when walking from each temporary destination to the destination is obtained, and parking fee information included in the temporary destination information To get. For example, a parking fee of 1000 yen and a calorie consumption of 15 kcal are obtained as values relating to a warning item when a vehicle travels from the vehicle position to the parking lot A by a car and walks on the route from the parking lot A to the destination. . In addition, for example, as a value related to a reminder item when driving a route from the vehicle position to the parking lot B by a car and walking along the route from the parking lot B to the destination, a parking fee of 500 yen and a calorie consumption of 60 kcal Is required. In addition, for example, as a value related to a reminder item when a vehicle travels from the own vehicle position to the parking lot C and walks along the route from the parking lot C to the destination, a parking fee of 300 yen and a calorie consumption of 120 kcal Is required.

  The search route combining unit 1152 uses the destination information and the estimated arrival time, the temporary destination information and the estimated arrival time, and the destination including the temporary destination based on the alert item and the value in each route related to the alert item. For each location, the estimated arrival time and the alert item are combined and associated. A parking fee of 1000 yen when traveling by car from the vehicle position to the destination can be obtained from the destination information. Also, for example, these associated data are input to the display unit 106 as display data. The display unit 106 displays the input display data.

  As a result, as shown in FIG. 4, the destination, specifically the destination designated by the user (user destination), the temporary destination set based on the destination, specifically the parking lot A , B and C (proposed parking lots A, B and C), estimated arrival times, specifically 10:10, 10:10, 10:35 and 11:00, respectively, calories burned, specifically Displays 15 kcal, 60 kcal and 120 kcal for parking lots A, B and C, respectively, and parking charges, specifically 1000 yen, 1000 yen, 500 yen and 300 yen, respectively.

  As described above, in the present embodiment, based on the destination designated by the user, in addition to the estimated arrival time when going to the destination by car, the temporary destination slightly away from the destination, the temporary destination A value for the predicted arrival at the destination via the destination and the alert items at each temporary destination is proposed. According to FIG. 4, when going to the destination via the parking lot A set as the temporary destination, the estimated arrival time and the parking fee are the same as when going directly to the destination set by the user. However, it can be seen that 15 kcal of calories can be consumed. In addition, when going to the destination via the parking lot C set as the temporary destination, the estimated arrival time is delayed by about 50 minutes compared with the case of going directly to the destination set by the user. It turns out that parking fees are cheaper and 120 kcal of calories can be consumed.

  The user displays the destination displayed on the display unit 106, the estimated arrival time at the destination, the temporary destination, the predicted arrival time at the destination via the temporary destination, and each temporary destination. A route to go to the destination is selected based on the value related to the alert item on the ground. Since the user can select from a plurality of routes, the degree of freedom of route selection can be expanded. In addition, as a reminder item, an item that is easy for the user who sets the destination to draw attention, for example, calorie consumption, number of steps, walking time, walking distance, etc., as described above, can be used to call attention to health for each user. Proposed route.

  The route guidance processing unit 116 guides the vehicle on which the navigation device 100 is mounted according to the route selected by the user among the routes displayed on the display unit 106.

  The map database 118 is a database that stores map information.

  The past selected route recording unit 120 records the characteristics of the route selected by the user. For example, as shown in FIG. 5, the number of health improvement route proposals, the user-selected route breakdown, and the health proposal method are recorded in association with each other. Here, the number of health improvement route proposals indicates the number of times that a route to the destination via the temporary destination is proposed as described above. The user selected route breakdown shows the characteristics of the route selected by the user. For example, one of “direct”, “low calorie consumption”, “high calorie consumption”, “low charge”, and “time priority” is selected. Here, “Direct” indicates that the route directly to the destination is selected, and “Low calorie consumption” indicates that the calorie that can be consumed from the temporary destination to the destination is low, for example, only 100 kcal-200 kcal is consumed. “Large calorie consumption” indicates that a calorie that can be consumed from the temporary destination to the destination is high, for example, a route that consumes 400 kcal-800 kcal is selected. "Indicates that a route with a low parking fee, for example 600 yen or less, has been selected, and" Time priority "indicates an increase within a predetermined time, for example 10 minutes, compared to the case where the estimated arrival time goes directly to the destination. Indicates that a route with an increase of within was selected. This feature is an example and can be changed as appropriate. Based on the route selected by the user, the control unit 110 determines whether the route is a route proposed for improving health, that is, a route going to the destination via the temporary destination. If the selected route is not a route proposed for improving health, the “direct” of the user-selected route breakdown is counted up. When the selected route is a route proposed for improving health, it is applicable to “low calorie consumption”, “high calorie consumption”, “low charge”, and “time priority” in the user-selected route breakdown. Count up items.

  The health suggestion method is set by the alerting item setting unit 112 and indicates the alerting item presented when displaying the searched route. For example, “calorie consumption”, “steps”, “walking distance”, etc. One of them is selected. The alerting item setting unit 112 determines, based on the alerting item displayed on the display unit 106, which of the health suggestion methods the alerting item corresponds to, and counts up the corresponding item. In the past selection route recording unit 120, the table shown in FIG. 5 may be created for each user, or may be created for each navigation device, that is, for each mounted vehicle. From the viewpoint of being able to present an alert item that often selects a health improvement route for each user, it is preferable to create the table shown in FIG. 5 for each user. According to FIG. 5, there is a tendency to select a route that consumes more calories than the arrival time and the parking fee is cheaper. When calorie consumption is selected as a reminder item, a health improvement route is selected. You can see that there are many. Therefore, for such a user, it is possible to propose a route according to the user's request by proposing many routes with a high calorie consumption and a low parking fee. In addition, the search route combination unit 1152 selects a reminder item based on the health suggestion method recorded in the past selection route recording unit 120. For example, for each user, an alert item that often selects a health improvement route is selected. For example, for the user, the search route combining unit 1152 selects calorie consumption and a parking fee as the alert items, and associates the selected alert items with each other.

  Next, the operation of the navigation device 100 according to the present embodiment will be described with reference to FIG.

  The destination input by the user is set (step S602). For example, the user designates a destination by operating the operation unit 104.

  The route search unit 1144 searches for a travel route by the automobile to the set destination (step S604).

  The temporary destination setting unit 1146 searches for a place that can be moved to the set destination on foot. For example, as a temporary destination, a parking lot slightly away from the set destination is selected (step S606). For example, the temporary destination setting unit 1146 searches for a parking lot and obtains the parking lot location and parking fee information.

  The route search unit 1144 searches for a route from the parking lot searched for as the temporary destination to the destination. The alert item calculation unit 1150 calculates the distance from the set destination to the parking lot searched as the temporary destination, and calculates calories consumed when walking the distance (step S608).

  The arrival time calculation unit 1148 obtains the walking time when walking from the parking lot searched as the temporary destination to the destination (step S610).

  The route search unit 1144 searches for a route from the vehicle position to the parking lot searched as a temporary destination (step S612).

  The arrival time calculation unit 1148 obtains the travel time when the vehicle travels from the vehicle position to the parking lot searched as the temporary destination by car, and sums the travel time and the walking time from the parking lot to the destination. The arrival time when going from the vehicle position to the destination via the temporary destination is calculated.

  The search route combining unit 1152 associates and combines the estimated arrival time, the calorie consumption, and the parking fee of the parking lot for each route (step S614).

  Here, the search route combining unit 1152 is based on the health suggestion method stored in the past selected route recording unit 120, and among items that the user is likely to call out, for example, calorie consumption, number of steps, walking time, walking distance, etc. It may be determined whether or not any of them should be combined.

(Second embodiment)
A navigation apparatus 100 as a route guidance apparatus according to a second embodiment of the present invention will be described with reference to FIG. The navigation device 100 according to the present embodiment determines whether or not to propose a route (health improvement route) for stimulating and promoting health improvement (promotion) in the navigation device according to the first embodiment. It is a thing.

  The navigation device 100 according to the present embodiment is the navigation device 100 described with reference to FIG. 1, and includes a health improvement route suggestion determination unit 122 and a past suggestion status recording unit 124 as route presentation determination means. It is.

  The health improvement route proposal availability determination unit 122 determines whether or not to propose a health improvement route based on information recorded in a past proposal status recording unit 124 described later.

  The past suggestion status recording unit 124 stores the reason why the user did not select the health improvement route when the user selected a route that goes directly to the destination even though the health improvement route was proposed in the past. The For example, as shown in FIG. 9, “route search count”, “health improvement route proposal count”, “suggestion rejection count”, and “rejection reason breakdown” are associated and recorded. Here, the number of route searches indicates the number of route searches performed in the route search processing unit 114. This route search includes a route going directly to the destination and a route going to the destination via the temporary destination. The number of health improvement route proposals indicates the number of times that a route to the destination via the temporary destination is proposed among the route search times. The number of proposal rejections indicates the number of times that a route directly to the destination is selected by the user among the number of route searches. The reason for refusal is that, when a route directly going to the destination is selected by the user, the reasons why the route going to the destination via the temporary destination is not selected are tabulated for each reason.

  Based on the route selected by the user, the control unit 110 determines whether the route is a health improvement route, that is, a route that goes to the destination via the temporary destination. If the selected route is not a proposed route for improving health, the reason for not selecting is recorded. For example, the reason for not selecting the route to go to the destination via the temporary destination when the route directly to the destination set by the user is selected from the routes displayed on the display unit 106. An inquiry is made. For example, the reason for not selecting may be selected from a plurality of options. For example, you may make it select from "emergency instruction", "weather condition", "bad physical condition", "there is a passenger", and "unknown (other)". Here, the emergency instruction is, for example, a case where it is necessary to rush to the destination. According to FIG. 9, the reason for refusal of bad weather is as many as 90 out of 200 proposal refusal times, so it is estimated that this user has a high probability of refusing to propose a health improvement route when the weather is bad. Is done.

  The health improvement route proposal availability determination unit 122 determines whether or not to propose a health improvement route based on the reason for refusal recorded in the past proposal status recording unit 124. For example, the health improvement route suggestion determination unit 122 determines that the possibility of selecting a health improvement route is low among the reasons for refusal, specifically, the refusal for which the number of reasons for refusal is equal to or more than a predetermined number of times. Judge whether the current situation is applicable to any of the reasons, and if so, make a decision not to propose a health improvement route, and if not, make a decision to propose a health improvement route I do. For example, for a user who corresponds to the reason for refusal shown in FIG. 9, since the number of times in the case of bad weather is high, it is determined that the possibility of selecting a health improvement route is low, and thus health improvement. Make a decision not to propose a route. By doing in this way, the load of the process which searches a health improvement path | route can be reduced.

  As shown in FIG. 10, the route search processing unit includes the route search processing unit 114 described with reference to FIG. 2 and the health improvement route proposal determined by the destination setting unit 1142 in the health improvement route proposal availability determination unit 122. It is different in that the determination result of whether or not is possible is input. Based on the input determination result, the destination setting unit 1142 inputs destination information to the temporary destination setting unit 1146 and the route search unit 1144 when the determination result is a determination to propose a health improvement route. If the determination result is a decision not to propose a health improvement route, the destination information is not input to the temporary destination setting unit 1146 but only to the route search unit 1144. As a result, a temporary destination is set only when a health improvement route is proposed.

  Next, the operation of the navigation device 100 according to the present embodiment will be described with reference to FIG.

  The destination input by the user is set (step S1102). For example, the user inputs a destination by operating the operation unit 104.

  The route search unit 1144 searches for a travel route by the automobile to the set destination (step S1104).

  The health improvement route proposal availability determination unit 122 determines whether or not to propose a health improvement route based on the information stored in the past proposal status storage unit 124 (step S1106). For example, the health improvement route suggestion determination unit 122 determines whether or not urgency is designated by the user, and when the urgency (emergency instruction) is not designated by the user (step S1106: YES), health improvement It is determined that the route is proposed. On the other hand, when the urgency is designated by the user (step S1106: NO), the process proceeds to step S1118 described later.

  Next, a determination is made as to whether it is possible to propose health improvement by personal adaptation (step S1108). For example, it is determined whether or not information on a previously selected route regarding the user who has input the destination is recorded in the past selected route recording unit 120. When it is recorded in the past selected route recording unit 120 (step S1108: YES), a health improvement route is proposed in accordance with the user's preference. On the other hand, when it is not recorded in the past selected route recording unit 120 (step S1108: NO), the process proceeds to step S1118 described later.

  The temporary destination setting unit 1146 searches for a place that can be moved to the set destination on foot. For example, as a temporary destination, a parking lot that is slightly away from the set destination is searched (step S1110).

  The route search unit 1144 searches for a route from the parking lot searched for as the temporary destination to the destination. The alert item calculation unit 1150 calculates the distance from the set destination to the parking lot searched as the temporary destination, and calculates calories consumed when walking the distance by walking (step S1112).

  The arrival time calculation unit 1148 obtains the walking time when walking from the parking lot searched as the temporary destination to the destination (step S1114).

  The route search unit 1144 searches for a route from the vehicle position to the parking lot searched as a temporary destination (step S1116).

  The arrival time calculation unit 1148 obtains the travel time when the vehicle travels from the vehicle position to the parking lot searched as the temporary destination, and sums the travel time and the walking time, and calculates the temporary destination from the own vehicle position. The arrival time when going to the destination via is calculated.

  The search route combining unit 1152 associates and combines the estimated arrival time, the calorie consumption, and the parking fee of the parking lot for each route (step S1118). Further, the search route combining unit 1152 is searched in step S1104 when it is determined that there is urgency in step S1106 and it is not determined in step S1108 that a health improvement route by personal adaptation can be proposed. And the estimated arrival time when the travel route is used.

  Here, the search route combining unit 1152 is based on the health suggestion method stored in the past selected route recording unit 120, and among items that the user is likely to call out, for example, calorie consumption, number of steps, walking time, walking distance, etc. It may be determined whether or not any of them should be combined.

  The display unit 106 displays the search route (step S616). The display unit 106 may be configured by an in-vehicle device display, or may be configured by a user interface corresponding to the in-vehicle device. In addition to the display by the display unit 106 or instead of the display, the voice synthesis unit 108 may perform voice guidance.

  Next, a data flow in the navigation device 100 according to the present embodiment will be described with reference to FIG.

  When the destination input by the user is set (step S1102), the route search unit 1144 searches for the travel route by the car to the set destination based on the map information stored in the map database 118. I do. The arrival time calculation unit 1148 obtains the estimated arrival time when the vehicle travels on the route obtained by the search (step S1104). As a result, the travel route by the automobile and the estimated arrival time are obtained. The search route combining unit 1152 temporarily accumulates the obtained travel route by the automobile and the estimated arrival time.

  The health improvement route proposal availability determination unit 122 determines whether or not to propose a health improvement route based on the information accumulated in the past proposal status storage unit 124, and can further propose health improvement by personal adaptation. It is determined whether or not there is (step S1107).

  For example, when determining whether or not to propose a health improvement route, the health improvement route proposal availability determination unit 122 includes a breakdown of rejection reasons accumulated in the past proposal status accumulation unit 124, specifically an emergency instruction ( Urgentness), bad weather (weather), poor physical condition (physical condition), presence of passengers, and other past proposals, the current situation is unlikely to be selected as a health improvement route among the reasons for refusal It is judged whether it corresponds to one of the reasons judged. Further, for example, when determining whether or not it is possible to propose health improvement by personal adaptation, information on a previously selected route regarding the user who has input the destination is the past selected route recording unit 120. It is determined whether or not it is recorded in

  Routes selected in the past for the user who entered the destination, and the current situation does not correspond to any of the reasons for refusal that it is determined that the possibility of selecting a health improvement route is low Is recorded in the past selected route recording unit 120 (step S1107: YES), it is determined that a health improvement route is proposed. On the other hand, the current situation corresponds to one of the reasons why it is determined that the possibility of selecting the health improvement route is low among the reasons for refusal, or the route selected in the past regarding the user who entered the destination Is not recorded in the past selected route recording unit 120 (step S1107: NO), the process proceeds to step S1118 described later.

  The temporary destination setting unit 1146 searches for a temporary destination based on the set destination, and searches for a route from the vehicle position to the destination via the temporary destination, that is, a health improvement route. (Step S1109). The temporary destination setting unit 1146 searches for a temporary destination based on the map information stored in the map database 118. The route search unit 1144 searches for a route from the parking lot searched for as the temporary destination to the destination. The arrival time calculation unit 1148 obtains the walking time when walking on the route obtained by the search. Further, the route search unit 1144 searches for a route from the vehicle position to the parking lot searched as a temporary destination. The arrival time calculation unit 1148 obtains the travel time when the vehicle travels from the vehicle position to the parking lot by the automobile, adds the travel time and the walking time, and goes from the vehicle position to the destination via the temporary destination. Calculate the arrival time of the case. As a result, the walking route and the estimated arrival time are obtained. The attention item calculation unit 1150 calculates the distance from the set destination to the parking lot searched as the temporary destination, and calculates the calorie consumption and the number of steps when walking the distance by walking. As a result, walking route / walking distance, walking route / walking time, walking route / consumed calories, walking route / number of steps, parking lot / parking fee data are required. The search path combining unit 1152 temporarily accumulates the obtained data.

  Based on the accumulated data, the search route combining unit 1152 determines, for each route, a travel route / estimated time by car, a walking route / walking time, a walking route / walking distance, a walking route / consumed calories, a walking route / step count, a parking lot. Parking lots and parking fees are associated and combined. In step S1107, the search path combining unit 1152 corresponds to one of the reasons for determining that the health improvement path is unlikely to be selected among the reasons for refusal, or When the information on the route selected in the past regarding the user who made the input is not recorded in the past selected route recording unit 120, the travel route searched in step S1104 and the estimated arrival time when the travel route is used Are combined (step S1108).
