Installed in the vehicle.

  The time acquisition means 10 is means for acquiring time information from the outside, and receives time information included in a GPS signal from a GPS satellite, for example. The database 20 is a storage unit that stores, in addition to general map data, parking lot map data and parking lot information for each parking lot. The vehicle position specifying means 30 is a means having a function of specifying the position of the vehicle, and for example, calculates and specifies the current position of the vehicle based on a GPS signal. Further, the vehicle position specifying means 30 determines whether or not the current position is a parking lot entrance based on the calculated current position and information in the database 20.

  The detection means 35 is a sensor that detects opening and closing of a door or window of the vehicle. The stop determination unit 40 is a unit that determines whether or not the vehicle has stopped. For example, the stop determination unit 40 determines whether or not the vehicle has stopped by receiving a vehicle speed from a vehicle speed sensor or a detection signal indicating whether or not the engine has stopped. The billing start time estimating unit 50 is a unit that estimates the time when the vehicle approached the parking lot entrance as the billing start time according to the determination of the stop determination unit 40 and the determination of the vehicle position specifying unit 30.

  The notification unit 60 is a unit that transmits the time obtained from the charging start time estimation unit 50 to the portable device 100 as the charging start time and notifies it. As the notification means 60, for example, the time is transmitted to the mobile device 100 by Bluetooth (registered trademark) communication or network communication.

  The mobile device 100 is a terminal possessed by the user, and has a function of notifying the user by processing the content received by a known technology and outputting the display or sound, for example, a mobile information device, a mobile phone, etc. Intelligent keys and smart keys for terminals and vehicles.

  The database 20 will be described with reference to FIG. As shown in FIG. 2, the database 20 stores parking lot map data 200 and parking lot information 210 for each parking lot. The parking lot map data 200 stores the parking lot position and the parking lot entrance position of each parking lot so that the parking lot position can be specified. For example, each parking lot is stored as coordinates on the map. The parking lot information 210 is information accompanying each parking lot stored as the parking lot map data 200, and includes a parking lot type 211 and a parking lot charge 212 for each parking lot.

The parking lot type 211 indicates, for example, the type depending on the size of the parking lot, the type depending on the charge, and the type depending on the structure. The scale of the parking lot is determined in advance in stages according to the number of accommodations, for example. For example, the type by charge indicates a type such as a time-based system, a flat-rate system, a time limit system, etc. in addition to a paid type and a free type. The types depending on the structure are, for example, flat land, three-dimensional self-propelled, mechanical tower, time limit parking section (parking meter), and the like.
The parking fee 212 indicates an amount of a fee set in advance for each parking lot. For example, a time-based parking lot is an amount per unit time or per day, and a fixed amount parking lot and a time limit system are predetermined amounts. Is set.

Next, the operation will be described.
FIG. 3 is a flowchart showing the processing operation of the notification device according to the first embodiment.
When the apparatus is activated, the vehicle position specifying means 30 inputs a GPS signal, performs calculation based on the GPS signal, and specifies the current position of the host vehicle. Moreover, the vehicle position specifying means 30 inputs the parking lot map data 200 from the database 20, and determines whether or not the current position of the host vehicle is the parking lot entrance based on the current position and the parking lot map data 200. (Step ST1). If the current position of the host vehicle is not the parking lot entrance (step ST1 “NO”), the process of step ST1 is repeated.

When the current position of the host vehicle is the parking lot entrance (step ST1 “YES”), the vehicle position specifying means 30 notifies the charging start time estimating means 50 to that effect. Upon receiving this notification, the charging start time estimating means 50 instructs the time acquiring means 10 to acquire the current time.
The time acquisition unit 10 acquires the current time from the outside in accordance with an instruction from the charging start time estimation unit 50 and sends it back to the charging start time estimation unit 50. The billing start time estimating unit 50 stores the time acquired by the time acquiring unit 10 (the time when the host vehicle approaches the parking lot entrance) (step ST2).

  Thereafter, the charging start time estimating means 50 determines whether or not the vehicle has stopped within a predetermined period after receiving the time when the own vehicle has approached the parking lot entrance from the time acquiring means 10. The means 40 is instructed. The stop determination means 40 determines whether or not the host vehicle has stopped according to the instruction from the charging start time estimation means 50 (step ST3). Here, if the host vehicle does not stop within a predetermined period (step ST3 “NO”), the process returns to step ST1.

  If the host vehicle stops within a predetermined period (step ST3 “YES”), the stop determination means 40 returns a message to that effect to the charging start time estimation means 50. When the charging start time estimating means 50 receives the determination result that the own vehicle has stopped within a predetermined period from the stop determining means 40, the charging start time estimating means 50 determines whether the own vehicle is in the parking lot with respect to the vehicle position specifying means 30. Is instructed to determine.

The vehicle position specifying unit 30 determines whether or not the position where the host vehicle is stopped is in the parking lot in accordance with the instruction from the charging start time estimating unit 50 (step ST4). If the stop position of the host vehicle is not in the parking lot (step ST4 “NO”), the process returns to step ST1.
If the stop position of the host vehicle is in the parking lot (step ST4 “YES”), the vehicle position specifying means 30 returns that fact to the charging start time estimating means 50.

  When the billing start time estimating means 50 receives from the vehicle position specifying means 30 that the stop position of the host vehicle is in the parking lot, the charging start time estimating means 50 uses the time stored in step ST2 (the time when the host vehicle approaches the parking lot entrance). It is estimated to be the time (charging start time) when the vehicle is stored in the parking lot and charging is started and is output to the notification means 60. The notification unit 60 transmits the charging start time input from the charging start time estimation unit 50 to the portable device 100 (step ST5) and ends the process.

  In the above description of the processing operation, the case where only the charging start time is transmitted and notified is shown. However, in addition to the charging start time, parking related information such as the parking fee 212 is transmitted to the portable device 100 for notification. You may make it do.

  Thereafter, the mobile device 100 displays or outputs the processed content based on the charging start time received by a known technique, and notifies the user of the content. For example, the mobile device 100 receives the charging start time, counts the time with a counter (not shown) in the mobile device 100, and visually displays the elapsed time (count time) from the charging start time. The mobile device 100 receives the charging start time and the parking fee 212 of the parked parking lot, calculates the elapsed time from the charging start time and the parking fee up to the current time, and then determines the parking fee. Calculate the remaining time until going up and display the parking fee and remaining time until the current time. Furthermore, when the mobile device 100 has an alarm function and the elapsed time from the charging start time reaches a predetermined time, or when the parking lot type 211 has passed the predetermined time of the time-limited parking lot, a voice output is performed. To notify the user. Note that the mobile device 100 may include a position detection unit and notify the user in consideration of the distance between the host vehicle and the mobile device 100.

  As described above, according to the first embodiment, when the own vehicle position is the parking lot entrance, the time when the own vehicle is located at the parking lot entrance is stored, and within a predetermined time after storing this time. When the host vehicle stops and the stop position of the host vehicle is in the parking lot, the stored time is estimated as the charging start time and transmitted to the user's portable device 100. The warehousing time at which charging is started after the parking table is acquired at the parking lot entrance can be transmitted to the mobile device 100 as the charging start time. As a result, it is possible to notify the user of an accurate charging start time.

Further, in the first embodiment, as shown in FIG. 5, a correction unit 70 that directly corrects the charging start time estimated by the charging start time estimation unit 50 by the user may be provided.
The correction means 70 shown in FIG. 5 is configured such that the user can correct the charging start time manually. The correcting means 70 is configured to display the charging start time estimated by the charging start time estimating means 50, for example, so that the user can change the value of the charging start time using an input means (not shown). With this configuration, even if the estimated charging start time is deviated, the charging start time can be corrected to an accurate time.

Furthermore, in this Embodiment 1, you may utilize the detection result of the window opening / closing of the own vehicle by the detection means 35. FIG. For example, the charging start time estimating unit 50 specifies that the current position of the host vehicle is the parking lot entrance by the vehicle position specifying unit 30, and when the detecting unit 35 detects that the window is opened, Is estimated to be the time when the driver arrives at the parking lot entrance and the driver receives the parking table at the entrance to the parking lot, and this time is recorded as the billing start time.
In addition, you may utilize similarly the detection result of the opening / closing of the door of the own vehicle which the detection means 35 detected. In this way, it is possible to notify the user of a more accurate charging start time.

  Furthermore, in this Embodiment 1, you may comprise so that the time acquisition means 10 may acquire entrance time by DSRC communication. In this case, the time acquisition means 10 has a communication function for performing narrow area communication, and performs wireless communication with a parking fee collection device (not shown) of the target parking lot. For example, DSRC (Dedicated Short Range Communication) communication is used for the narrow area communication. A parking fee collection device (not shown) is provided at the position of the gate 301 of the parking lot 300 described above with reference to FIG. 4, for example, and transmits the entrance time as a parking start time to the vehicle entering the target parking lot. The parking fee 212 is transmitted. The time acquisition means 10 receives the warehousing time and the parking fee 212 from a parking fee collection device (not shown). By doing so, it is possible to notify the user of an accurate charging start time.

Embodiment 2. FIG.
In the first embodiment, when the own vehicle stops in the parking lot, the time when the own vehicle is located at the parking lot entrance is estimated as the charging start time and transmitted to the user's portable device 100. Form 2 will describe a configuration in which the charging start time is estimated based on the required stop time for each parking lot type. The notification device 1 according to the second embodiment has the same configuration as that of the notification device 1 according to the first embodiment, and will be described with reference to FIG. 1, and the description of the configuration having the same function is omitted.

  As shown in FIG. 1, the notification device 1 includes a time acquisition unit 10, a database 20, a vehicle position identification unit 30, a detection unit 35, a stop determination unit 40, a charging start time estimation unit 50, and a notification unit 60.

  The database 20 stores parking map data and parking information for each parking lot in addition to general map data. Here, the database 20 will be described with reference to FIG. As shown in FIG. 6, the database 20 stores parking lot map data 200 and parking lot information 210 for each parking lot. The parking lot map data 200 stores the parking lot position and the parking lot entrance position of each parking lot so that they can be specified. For example, each parking lot is stored as coordinates on the map. The parking lot information 210 is information that accompanies each parking lot stored as the parking lot map data 200, and includes a parking lot type 211, a parking fee 212, and a required stop time 213 for each parking lot.

  The required entry time 213 is preset according to the parking lot type 211 for each parking lot, and is an average required time from entering the parking lot to actually parking (entering). The required entry time 213 is set to, for example, 5 minutes for a medium-sized flat parking lot and 10 minutes for a large-scale three-dimensional self-propelled parking lot.

  The charging start time estimation unit 50 shown in FIG. 1 is based on the time when the host vehicle stops at the parking lot and the required stop time 213 when the host vehicle stops at the parking lot according to the determination of the stop determination unit 40 and the determination of the vehicle position specifying unit 30. Thus, the charging start time is calculated and estimated.

Next, the processing operation of the notification device 1 according to the second embodiment will be described. FIG. 7 is a flowchart showing the processing operation of the notification device 1 according to the second embodiment.
The communication means 10 starts processing operation when the host vehicle starts, repeatedly receives GPS signals from GPS satellites, and outputs the GPS signals to the vehicle position specifying means 30. When the GPS signal is input from the communication unit 10, the vehicle position specifying unit 30 performs a calculation based on the GPS signal and specifies the current position of the host vehicle (step ST101).

  Moreover, the vehicle position specifying means 30 inputs the parking lot map data 200 from the database 20, and determines the current position based on the current position and the parking lot map data 200 (step ST102). The vehicle position specifying unit 30 determines that the current position of the host vehicle is a parking lot when, for example, the current position enters a parking lot stored in the parking lot map data 200 or when the current position exists in the parking lot for a certain period of time or longer. judge. When the vehicle position specifying means 30 determines in step ST102 that the current position is not a parking lot (step ST102 “NO”), the process returns to step ST101.

  When it is determined in step ST102 that the current position is a parking lot (step ST102 “YES”), the detection unit 35 detects the state of the vehicle and starts monitoring. The stop determination means 40 determines whether or not the vehicle has stopped based on the state of the vehicle detected by the detection means 35 (step ST103), and determines that the vehicle has not stopped (step ST103 "NO"). The process returns to step ST101.

  When it is determined in step ST103 that the vehicle is parked (step ST103 “YES”), the vehicle position specifying unit 30 is based on the GPS signal input from the communication unit 10 and the parking lot map data 200 input from the database 20. The current position is acquired (step ST104), and it is determined whether the parking position of the host vehicle is a parking lot (step ST105). In step ST105, for example, the current position of the host vehicle is compared with the parking lot position recorded in the parking lot map data 200. If the current position is within the parking lot range, the position where the own vehicle has stopped is determined as the parking lot. (Step ST105 “YES”), and when the current position is not within the parking lot range, it is determined that the position where the host vehicle has stopped is not the parking lot (step ST105 “NO”). When it is determined that the stop position of the host vehicle is not a parking lot (step ST105 “NO”), the processing operation is terminated (END).

  If it is determined in step ST105 that the stop position of the host vehicle is in the parking lot (step ST105 “YES”), charging start time estimating means 50 acquires the current time from the built-in clock and stores it as the parking lot entry time. (Step ST106). Subsequently, the billing start time estimating means 50 acquires the parking lot information 210 of the parking lot where the host vehicle has stopped from the database 20 (step ST107). In step ST106, the current time is acquired from the built-in clock, but the time may be extracted from the GPS signal.

  The charging start time estimating means 50 determines whether or not the warehousing time needs to be corrected based on the parking lot type 211 of the parking lot information 210 acquired in step ST107 (step ST108). In step ST108, the charging start time estimation means 50 confirms the required entry time 213 of the parking lot type 211, for example, and if the required entry time 213 is not 0 (required entry time 213 ≠ 0), the receipt time is set to the required entry time 213. It is determined that it is necessary to estimate the charging start time by correcting (step ST108 “YES”), and when the required warehousing time 213 is 0 (required warehousing time 213 = 0), the warehousing time is the charging start time, It is determined that no correction is required (step ST108 “NO”).

  If it is determined in step ST108 that the warehousing time needs to be corrected by the required warehousing time 213 (step ST108 "YES"), the charging start time estimating means 50 obtains the required warehousing time 213 for the parked parking lot from the database 20. (Step ST109). The charging start time estimating means 50 calculates and corrects a time obtained by subtracting the required warehousing time 213 acquired in step ST109 from the warehousing time acquired in step ST106, and sets the charging start time (the warehousing time−the required warehousing time = the charging start time). ) Is estimated (step ST110). The notification unit 60 transmits the charging start time estimated in step ST110 to the mobile device 100 (step ST112) and ends the process (END).

  On the other hand, when it is determined in step ST108 that the warehousing time does not need to be corrected (“NO” in step ST108), the charging start time estimating unit 50 sets the warehousing time acquired in step ST106 as the charging start time (receipt time = charging start time). ) (Step ST111) and output to the notification means 60. The notification unit 60 transmits the charging start time input from the charging start time estimation unit 50 to the portable device 100 (step ST112) and ends the process (END).

  In the description of the processing operation, only the charging start time is transmitted and notified, but in addition to the charging start time, parking related information such as the parking fee 212 is transmitted to the portable device 100 for notification. Also good.

  As described above, according to the second embodiment, the database 20 stores the parking lot map data 200 and the parking lot information 210, and the vehicle position specifying means 30 is based on the current position and the parking lot map data 200. It is determined whether the position is a parking lot, the detection unit 35 detects the state of the vehicle, the stop determination unit 40 monitors the state of the vehicle to determine whether the vehicle is parked, and the charging start time estimation unit 50 The warehousing time is memorized and the warehousing time 213 of the parked parking lot is obtained, the time obtained by subtracting the warehousing time 213 from the warehousing time is estimated to estimate the charging start time, and the notification means 60 carries the charging start time. Since it is configured to transmit to the device 100, it is possible to correct the deviation between the warehousing time and the actual charging start time, and to transmit the charging start time with little deviation to the portable device 100. As a result, it is possible to notify the user of an accurate charging start time.
