(Embodiment)
(Functional configuration of navigation device)
A functional configuration of the navigation device 100 according to the embodiment of the present invention will be described. FIG. 1 is a block diagram illustrating an example of a functional configuration of the navigation device 100 according to the embodiment. In FIG. 1, a navigation device 100 can communicate with an information management server that manages traveling data of a plurality of mobile objects, and includes a setting unit 101, an acquisition unit 102, a determination unit 103, a detection unit 104, and a calculation. Unit 105, transmission unit 106, storage unit 107, input unit 108, control unit 109, reception unit 110, search unit 111, guidance unit 112, and measurement unit 113.

  In the setting unit 101, a destination is set. The destination is specifically a facility, in particular, a facility having a parking lot adjacent to the facility or a facility having a parking lot associated with the facility.

  The acquisition unit 102 acquires information on the current position of the moving object. Specifically, the current position information is information calculated based on output information of a GPS unit and various sensors provided in the navigation device 100.

  Based on the destination position information set in the setting unit 101 and the current position information of the moving body acquired by the acquiring unit 102, the determination unit 103 sets a predetermined range in which the moving body is preset from the destination. It is determined whether it is located within. The predetermined range is around the facility as the destination, for example, a range where traffic around the facility may occur due to a vehicle heading to the facility.

  The detection unit 104 detects that the moving body has parked at the destination. The detection unit 104 may detect that the vehicle has parked when the moving object has stopped at the destination for a predetermined time or more. Typically, as described later, the position of the gear, the position of the parking brake, What is necessary is just to detect having parked by the engine stop. In addition to parking at the facility as the destination, parking at the destination is to park at a position within a predetermined range from the destination, or park at a parking lot associated with the facility at the destination in advance. Including.

  When the determination unit 103 determines that the moving body is located within a predetermined range set in advance from the destination (hereinafter referred to as “determination time”), the calculation unit 105 detects the moving body at the destination of the moving body. A time (hereinafter referred to as “parking waiting time”) until parking is detected (hereinafter referred to as “parking time”) is calculated. That is, the parking waiting time calculated by the calculating unit 105 includes the waiting time on the surrounding roads. The transmission unit 106 transmits the parking waiting time calculated by the calculation unit 105 to the information management server.

  Moreover, in this Embodiment, the detection part 104 may detect that the moving body parked by the position of the gear of a moving body, or the position of a parking brake. In this case, the calculation unit 105 calculates the parking waiting time from the determination time to the parking time based on the detection of the position of the gear of the moving body or the position of the parking brake by the detection unit 104. Moreover, the transmission part 106 transmits the information regarding a destination, and the parking waiting time calculated by the calculation part 105 to an information management server. Note that the information regarding the destination includes the name of the destination (facility name when the destination is a facility), position information, and the like.

  The position of the gear when detecting the parking of the moving body may be a neutral position, but a typical example is a parking position of an automatic vehicle. Further, the position of the parking brake when detecting the parking of the moving body is specifically the position where the parking brake is applied. In addition, you may detect the parking of a moving body based on each position of a gear and a parking brake. Specifically, the position of a gear is located in a parking position or a neutral position, and the parking brake is applied. In this case, parking of the moving body may be detected.

  In this configuration, the calculation timing of the parking waiting time by the calculation unit 105 and the transmission timing of the parking waiting time by the transmission unit 106 are based on the position of the gear of the moving body or the position of the parking brake by the detection unit 104. This is when a moving object is parked. Thus, this structure transmits a parking waiting time to an information management server before a moving body parks and turns off an engine, and transmits real-time information to an information management server. .

  In addition, the transmission timing of the information on the destination and the parking waiting time is detected by the detecting unit 104 when the moving unit is parked based on the gear position of the moving unit or the parking brake position. In addition to the time when the waiting time is calculated, the engine may be restarted after the moving body is parked and the engine is stopped.

  In the present embodiment, the storage unit 107 is an arbitrary component. In this case, the detection unit 104 detects that the moving body is parked when the engine of the moving body stops at the destination. Then, the storage unit 107 stores the determination time and the parking time based on the detection of the stop of the moving body engine by the detection unit 104. The calculation unit 105 calculates a parking waiting time based on the parking time and the determination time stored in the storage unit 107 when the engine of the moving object is restarted. Moreover, the transmission part 106 transmits the parking waiting time calculated by the calculation part 105 to an information management server.

  For example, the detection unit 104 may detect that the moving body is parked when the engine key is off or is positioned in the ACC (accessory power supply), depending on the position of the engine key. By detecting the engine speed, specifically, when it is detected that the engine speed has become 0, it may be detected that the moving body is parked. Similarly, detection of engine restart may be detected when the position of the engine key is on, or may be detected when the engine speed is other than zero. This configuration is designed to detect the parking of the moving body when the engine is stopped, and can easily and reliably detect the parking of the moving body.

  Further, when the moving body engine stops at the destination, the detection unit 104 may detect the stop of the moving body immediately before the engine stops as parking at the destination of the moving body. In this case, the storage unit 107 may store the determination time and the parking time based on the detection of the stop of the moving object on the detection date 104. The calculation unit 105 calculates a parking waiting time based on the parking time and the determination time stored in the storage unit 107 when the engine of the moving body is restarted. In this configuration, a more accurate parking waiting time can be calculated by excluding the time from stopping at the parking lot to turning off the engine.

  In the present embodiment, the input unit 108 and the control unit 109 are arbitrary components. The input unit 108 receives input of evaluation information for a facility at a destination reached by the mobile object. Specifically, the evaluation information is, for example, word-of-mouth information from the user regarding the atmosphere, price, and service of the facility.

  The control unit 109 performs control for prompting input of evaluation information from the input unit 108 when the engine of the moving object is restarted after parking is detected by the detection unit 104. Specifically, the control for prompting the input of the evaluation information is, for example, control for performing display for accepting input from the user on the display screen.

  In this case, the transmission unit 106 transmits the evaluation information from the user input to the input unit 108 and the parking waiting time calculated by the calculation unit 105. In this configuration, since the parking waiting time is transmitted together with the transmission of the evaluation information, the parking waiting time can be transmitted to the information management server without any complicated input for the user.

  In the present embodiment, the position information of the destination may be position information of the entrance of the parking lot associated with the destination facility in advance. In this case, the predetermined range may be a predetermined distance from the entrance of the parking lot. The predetermined distance is specifically a road. This configuration makes it possible to calculate an accurate parking waiting time for each road.

  In the present embodiment, the location information of the destination may be location information of the facility at the destination. In this case, the predetermined range may be a predetermined radius centered on the destination facility. This configuration enables calculation of the parking waiting time even when there is no parking lot associated with the destination or when the entrance of the parking lot is unknown.

  Moreover, in this Embodiment, the receiving part 110, the search part 111, and the guidance | induction part 112 are arbitrary components. When the destination is set in the setting unit 101, the receiving unit 110 receives, from the information management server, the parking waiting time at the destination calculated by another moving body. Search unit 111 searches for a route to the destination using the parking waiting time received by receiving unit 110. The guide unit 112 guides a route to the destination searched by the search unit 111. This configuration receives the parking waiting time of each parking lot managed by the information management server, and makes it possible to perform a route search in consideration of the parking waiting time.

  In the present embodiment, the measurement unit 113 is an arbitrary component. The measurement unit 113 is provided in the calculation unit 105 and measures the time from the determination time to the current time before reaching the destination. In this case, when the time measured by the measurement unit 113 exceeds a predetermined time, the search unit 111 searches again for a route to another parking lot. This configuration takes into consideration the case where a traffic jam occurs after the moving body is located in a predetermined range around the destination, and enables re-searching after it is located in the predetermined range.

(Information transmission procedure of navigation device)
Next, the information transmission processing procedure of the navigation device 100 will be described with reference to FIG. FIG. 2 is a flowchart showing an example of an information transmission processing procedure of the navigation device 100 according to the present embodiment.

When the destination is set (step S201: Yes), based on the destination position information set in the setting unit 101 and the current position information of the moving body acquired by the acquisition unit 102, the moving body It is determined whether or not the vehicle is located within a predetermined range from the destination (step S202). It is assumed that information on the current position of the mobile object is always acquired by the acquisition unit 102.

  If it is determined in step S202 that the moving body is in a standby state until it is within the predetermined range from the destination (step S202: No loop), and it is determined that the moving body is within the predetermined range from the destination (step S202: Yes) ), It is determined whether or not the moving object has been parked (step S203).

  In step S203, the vehicle is in a standby state until it detects parking of the moving body (step S203: No loop). When parking of the moving body is detected (step S203: Yes), a parking waiting time is calculated (step S204). Then, the information regarding the destination and the calculated parking waiting time are transmitted to the information management server (step S205), and the series of processes is terminated.

  As described above, the navigation device 100 according to the present embodiment calculates the parking waiting time from when the moving body is located within a predetermined range from the destination until it is detected that the vehicle has parked at the destination. The information regarding the destination and the calculated parking waiting time are transmitted to the information management server. Thereby, the congestion information around the destination can be easily obtained without requiring input from the user.

  In addition, the user can know the required time to the destination by receiving the congestion information from the information management server during route search, and can change the destination according to the degree of congestion. . According to such a configuration, the user can know in advance the degree of congestion around the destination, so that it is possible to prevent the vehicle from being parked even if it is close to the destination, and traffic congestion occurs. Even if it is, the traffic jam can be expected.

(An example of other information transmission processing performed by the navigation device)
Next, another example of the information transmission process performed by the navigation device 300 according to the present embodiment will be described with reference to FIG. FIG. 7 is a flowchart illustrating another example of the information transmission process performed by the navigation device 300 according to the present embodiment. The information transmission process shown in FIG. 7 is different from the information transmission process shown in FIG. 5 (the parking waiting time is transmitted when the engine is started), and it is determined that the vehicle is parked when the gear position is at the parking position. The parking waiting time is calculated and the parking waiting time is transmitted to the information management server.

  In FIG. 7, the navigation apparatus 300 first determines whether or not a destination has been set (step S701). It is in a standby state until the destination is set (step S701: No loop). When the destination is set (step S701: Yes), the vehicle is positioned within a predetermined range from the destination based on the set location information of the destination and the acquired information on the current position of the moving body. Whether or not (step S702). Note that the current position of the vehicle is always acquired.

  In step S702, when the vehicle is in a standby state until it is located within a predetermined range from the destination (step S702: No loop), and when it is determined that the vehicle is located within the predetermined range from the destination (step S702: Yes), Time t1 when the vehicle is located within a predetermined range from the destination is recorded (step S703).

  Then, as a determination of whether or not the vehicle is parked, it is determined whether or not it has been detected that the position of the gear is positioned in the parking gear (step S704). Note that the determination in step S704 is not limited to determining whether or not it is detected that the vehicle is positioned in the parking gear, and may determine whether or not the parking brake is on.

  When it is determined in step S704 that it is in a standby state until it is detected that the gear position is located in the parking gear (step S704: No loop), and it is detected that the gear position is located in the parking gear (step S704) S704: Yes), “t2-t1”, which is a parking waiting time, is calculated (step S705). Note that t1 is the time when the vehicle is located within a predetermined range from the destination, and t2 is the time when it is detected that the position of the gear is located in the parking gear. Thereafter, the destination information and the parking waiting time are transmitted (step S706), and the series of processing ends. The destination information includes a destination name (a facility name when the destination is a facility), destination location information, and the like.

  According to the above-described processing, before the vehicle is parked and the engine is turned off, the information about the destination and the parking waiting time can be transmitted to the information management server, that is, the real-time information is transmitted to the information management server. be able to. The information management server can distribute the real-time information to other vehicles.

  In addition, the timing of transmitting the information about the destination and the parking lot waiting time is not limited to when the parking of the vehicle based on the gear position or the parking brake position is detected and the parking waiting time is calculated. It may be when the engine is restarted after parking and stopping the engine.

  In addition, parking waiting time includes accidental time such as waiting time for signals around the facility at the destination and the time until the gear is put into the parking gear after stopping at the parking lot. Since the information to be known is a rough time of the parking waiting time, such an accidentally occurring time is within the error range of the parking waiting time. Moreover, if the number of information (parking waiting time) collected by the information management server increases, the proportion of the accidentally occurring time included in the average parking waiting time decreases, and the error decreases accordingly.

(An example of a predetermined range from the parking lot associated with the destination)
Next, an example of a predetermined range from the parking lot associated with the destination will be described with reference to FIG. FIG. 8 is an explanatory diagram showing an example of a predetermined range from the parking lot associated with the destination.

  In FIG. 8, a parking lot 800 is a parking lot associated with a destination facility, and has an entrance 801. In this embodiment, a region at a distance r from the entrance 801 is set as a predetermined range. Assuming that the end points of the distance r are respectively positions S (S1 to S4), when the vehicle is positioned at the position S, it is determined that the vehicle is positioned within a predetermined range. Thus, if the position information of the entrance 801 of the parking lot 800 can be acquired, an accurate parking waiting time for each road can be calculated.

(An example of a predetermined range from the destination facility)
Next, an example of a predetermined range from the destination parking lot will be described with reference to FIG. FIG. 9 is an explanatory diagram showing an example of a predetermined range from the destination parking lot.

  In FIG. 9, a facility 900 is a destination set by the user, and it is assumed that the parking lot where the vehicle is parked and the entrance of the parking lot are unknown. In this case, a circle with a radius r centering on the facility 900 is drawn, and roads existing in the circle are defined as a predetermined range. Assuming that the intersection of this circle of radius r and the road is a position T (T1 to T5), when the vehicle is positioned at the position T, it is determined that the vehicle is positioned within a predetermined range. In this way, by drawing a circle with a radius r centered on the facility 900 and setting a road within the circle as a predetermined range, when there is no parking lot associated with the facility 900, Even when the entrance is unknown, the parking waiting time can be calculated.

  As described above, the navigation device 300 according to the present embodiment calculates the parking waiting time from when the vehicle is located within a predetermined range from the destination until it is detected that the vehicle is parked at the destination. The destination information and the calculated parking waiting time are transmitted to the information management server.
