Japanese Patent Laid-Open No. 2001-50760

  However, whether or not the past parking position is important as a destination for the user is not the length of the previous parking time of the parking position, but rather the length of the total parking time of a plurality of past parking opportunities. Tend to depend on

  In the present invention, in view of the above points, the vehicle navigation apparatus may perform display prioritized according to the length of the past comprehensive parking time for each parking position in the display of the parking position for specifying the destination. The purpose is to be able to.

  The invention according to claim 1 for achieving the above object includes a recording means for recording data of accumulated parking time over a plurality of parking periods for each parking position of the vehicle (hereinafter referred to as parking history data) on a storage medium; A plurality of parking positions included in the parking history data recorded by the recording unit are displayed on the display control unit, and the display control unit displays the parking position with a long cumulative parking time with higher priority on the image display device. A vehicle navigation apparatus comprising: destination specifying means for specifying, as a destination, one parking position selected by the user among the plurality of parking positions.

  Thus, since the vehicle navigation apparatus gives higher priority to the parking position with a long cumulative parking time over a plurality of parking periods in the display of the parking position for specifying the destination, the past comprehensive parking for each parking position. The display prioritized according to the length of time can be performed.

  Further, the invention according to claim 2 is the navigation device according to claim 1, wherein when the recording means parks for a certain time T at the position P, the position P is a parking position included in the parking history data. If they are the same, the value of the cumulative parking time corresponding to the parking position included in the parking history data is increased by the time T.

  By doing this, the sum of past parking times at the same parking position is recorded as parking history data, so prioritization based on cumulative parking time is compared to the case where the sum itself is not recorded. Can be done quickly. The “same parking position” here is a concept including not only the exact same position but also “two parking positions determined to satisfy some proximity criteria”.

  According to a third aspect of the present invention, there is provided recording means for recording data on cumulative parking time (hereinafter referred to as parking history data) over a plurality of parking periods for each parking position of the vehicle, and the recording means records the recording means. Display control means for displaying a plurality of parking positions included in the parking history data on an image display device with priority given to a parking position with a long cumulative parking time, and the plurality of display positions displayed on the display control means This is a program that causes a computer to function as destination specifying means for specifying one parking position selected by the user as a destination among the parking positions.

  Thus, the invention described in claim 1 can also be understood as a program.

  Hereinafter, an embodiment of the present invention will be described. In FIG. 1, the hardware block diagram of the vehicle navigation apparatus 1 which concerns on this embodiment is shown. As will be described in detail below, this vehicle navigation device 1 records the past cumulative parking time for each parking position of the host vehicle, and displays the parking positions in order of the cumulative parking time when setting the destination, What the user has selected from the plurality of parking positions is specified as the destination. As shown in FIG. 1, such a vehicle navigation device 1 includes a position detector 11, an operation switch group 12, an image display device 13, an audio circuit 14, a speaker 14a, a microphone 14b, a parking brake sensor 15, a RAM 16, a ROM 17, An external storage unit 18 and a control circuit 19 are provided.

  The position detector 11 includes a well-known sensor (not shown) such as a geomagnetic sensor, a gyroscope, a vehicle speed sensor, and a GPS receiver. The current position and direction of the vehicle based on the characteristics of each of these sensors. Is output to the control circuit 19.

  The operation switch group 12 includes a plurality of mechanical switches provided in the vehicle navigation device 1 and an input device such as a touch panel provided so as to overlap the display surface of the image display device 13. A signal based on the touch is output to the control circuit 19.

  The image display device 13 displays a video based on the video signal output from the control circuit 19 to the user. Examples of the display image include a map centering on the current location.

  The audio circuit 14 outputs an audio signal based on the audio data received from the control circuit 19 to the speaker 14 a and outputs audio data based on the audio signal detected by the microphone 14 b to the control circuit 19.

  The parking brake sensor 15 detects whether the parking brake of the vehicle is on (that is, the parking brake is effective) or off, and outputs a detection signal to the control circuit 19.

  The external storage unit 18 includes a nonvolatile storage medium such as an HDD and a device that reads and writes data to the storage medium, if possible, a program that the control circuit 19 reads and executes, and a map for route guidance Data etc. are memorized. The map data includes road data and facility data including link and node positions and types, connection relation information between nodes and links, and the like.

  A control circuit (corresponding to a computer) 19 executes a program for the operation of the vehicle navigation apparatus 1 read from the ROM 17 and the external storage unit 18, and in executing the program, the RAM 16, the ROM 17, and the external storage unit 18. Information is read from the RAM 16 and the information is written to the RAM 16 and the external storage unit 18, and signals are exchanged with the position detector 11, operation switch group 12, image display device 13, audio circuit 14, and parking brake sensor 15. The ignition key signal is received from the ignition line.

  Specific processing performed by the control circuit 19 executing the program includes current position specifying processing, destination specifying processing, guidance route calculation processing, route guidance processing, and the like.

  The current position specifying process is a process for specifying the current position and direction of the vehicle based on a signal from the position detector 11 using a known technique such as map matching. The destination specifying process is a process of specifying a destination based on a user operation on the operation switch group 12. The guidance route calculation process is a process for calculating an optimum guidance route from the current position to the destination specified by the destination specification process. In the route guidance process, map data is read from the external storage unit 18 and an image in which the calculated guide route, destination, waypoint, current position, etc. are overlaid on the map indicated by the map data is output to the image display device 13. In this process, a guidance voice signal instructing a right turn, a left turn or the like is output to the voice circuit 14 when the host vehicle needs to arrive before the guidance intersection.

  In the present embodiment, in the above-described destination specifying process, the past parking positions can be displayed in a list in the order of the accumulated parking time of the parking position. Therefore, the control circuit 19 records the parking history data in the HDD of the external storage unit 18 by repeatedly executing the parking history data recording program 100 with a short cycle (for example, a cycle of 1 second to 1 minute). Yes.

  In the execution of the parking history data recording program 100, the control circuit 19 first determines in step 105 whether or not the parking brake is on based on the detection signal from the parking brake sensor 15, and if not, Then, step 110 is executed, and if it is on, step 115 is executed subsequently.

  In step 110, the current time is recorded as a variable Tp in the HDD of the external storage unit 18, and then the execution of the parking history data recording program 100 is completed. In step 115, it is determined whether or not ACC is on based on the ignition key signal. If it is on, then step 120 is executed. If it is off, the parking history data recording program 100 is executed once. Exit.

  In step 120, the current time is recorded as a variable Tn in the HDD of the external storage unit 18. In step 125, the result of subtracting the value of the variable Tp from the value of the variable Tn in the HDD is set to L. Subsequently, in step 130, the current position is specified by the above-described current position specifying process.

  Subsequently, in step 135, the parking history data in the HDD of the external storage unit 18 is searched using the current position specified in step 130 as a search key. Parking history data is data which shows the parking time for every parking position. FIG. 3 shows an example of the parking history data in a table format. As described above, the parking history data includes a plurality of entries provided for each parking position, and each entry includes the parking position and parking time information as elements.

  In step 140, as a result of the search in step 135, it is determined whether or not there is an entry in the parking history data having the same position as the parking position used as the search key (that is, the current position) as an element. Here, whether or not they are the same position is determined by comparing the parking position used as the search key with the parking position in each entry, and whether or not the two positions satisfy the proximity criterion. The proximity reference may be, for example, a reference that “two positions are within a reference distance”. Here, the reference distance may be a fixed value stored in advance, or various conditions (for example, the current position and the registered home position of the owner of the own vehicle, which increase as the facility to which the current position belongs increases) The value may be changed based on a larger distance, or may be a value determined randomly within a certain range. If there is an entry having the same position as the parking position used as the search key as an element, step 145 is subsequently executed. If not, step 150 is subsequently executed.

  In step 145, the value of the parking time in the target entry determined to be the same position as the parking position used as the search key in step 140 is changed to a value obtained by adding the time L calculated in step 125 to that value. To do. That is, the value of the parking time in the entry is increased by L.

  In step 150, a new entry is added to the parking history data. The position in the entry is set to the same value as the parking position used as the search key, and the parking time is set to the same value as the time L calculated in step 125.

  Subsequent to steps 145 and 150, in step 155, the value of the current variable Tn is substituted into the above-described variable Tp. Specifically, the current value of the variable Tn is recorded as the variable Tp in the HDD of the external storage unit 18. After step 155, one execution of the parking history data recording program 100 is completed.

  By repeatedly executing such a parking history data recording program 100, the vehicle navigation apparatus 1 updates the value of Tp to the current time when the parking brake is off, that is, when the parking brake is not parked (see step 105). (See step 110). When the vehicle is parked at a certain position and the parking brake is turned on from off, first, a short elapsed time from the execution of the previous step 110 is calculated as L (see steps 120 and 125), and ACC is turned on thereafter. , The elapsed time from the previous repeat time is calculated as L every time the steps 120 and 125 are repeated. When the ACC is turned off, the time immediately before the ACC is turned off remains recorded in the external storage unit 18 as Tp (see step 155). The vehicle navigation device 1 stops operating several seconds after the ACC is turned off, and then starts when the ACC is turned on again.

  Also, when the vehicle ACC is turned off and then turned on again after a time, it goes through steps 105 and 115, and in steps 120 and 125, the time from immediately before the ACC is turned off to the present time, that is, ACC is off. Time is calculated as L. Then, until the parking brake is turned off, while the ACC is still on, the elapsed time from the previous repeat time is calculated as L every time the steps 120 and 125 are repeated.

  Each time L is calculated in this way, the parking time increases by L in the entry corresponding to the parking position in the parking history data (see steps 130 to 145). As a result, the parking time in the parking history data corresponding to the parking position is increased by one vehicle parking completed by a series of operations of parking brake on → ACC off → ACC on → parking brake off. The increased value is a period from immediately before the parking brake is turned on to immediately before the parking brake is turned off, that is, a substantial parking time. However, if there is no entry corresponding to the parking position, an entry corresponding to the parking position is newly created in the parking history data by one vehicle parking, and the parking time in the entry increases from 0. To do. The increase value is a period from immediately before the parking brake is turned on to immediately before the parking brake is turned off, that is, a substantial parking time, as described above.

  Thus, when the vehicle navigation apparatus 1 parks for a certain time T at the position P, the vehicle navigation apparatus 1 corresponds to the parking position included in the parking history data when the position P is the same as the parking position included in the parking history data. The value of the parking time is increased by the time T. By repeating the vehicular navigation device 1 every time the vehicle is parked, the parking history data directly stores data on the accumulated parking time over a plurality of past parking opportunities for each parking position of the vehicle.

  In addition, the control circuit 19 displays the past parking positions in order of the accumulated parking time for the operation switch group 12 in the destination specifying process in order to display a list of the past parking positions in the order of the longest accumulated parking time of the parking position. The parking history destination specifying program 200 starts to be executed based on a user operation to request the parking history.

  Then, in the execution of the parking history destination specifying program 200, the control circuit 19 first reads the parking history data from the external storage unit 18 in step 210, and then in step 220, all the entries of the parking history data are parked. The information is sorted in the order of the longest time, and the information (specifically, position and parking time) of each entry is displayed on the image display device 13 in a selectable order in the order of the sorting result. The selectable display means, for example, detecting which part of the list corresponding to one facility on the display screen of the image display device 13 the user has touched based on a signal from the touch panel. Say.

  Subsequently, in step 230, the control waits until there is an operation of the operation switch group 12 for selecting one of the displayed entries. If there is an operation, it is subsequently selected in step 240. The parking position corresponding to the entry is specified as the destination. After step 240, execution of the parking history destination specifying program 200 ends.

  By executing such a parking history destination specifying program 200, the vehicle navigation apparatus 1 can park a plurality of parking positions included in the accumulated parking time data for each parking position of the vehicle with a long accumulated parking time. A list display that gives priority to the display order of the positions is displayed on the image display device so as to be selectable (see steps 210 and 220), and a user's selection operation based on the list is accepted (see step 230). The resulting parking position is identified as the destination (see step 240).

  By the operation as described above, the vehicle navigation apparatus 1 gives higher priority to the parking position with a long accumulated parking time in the parking history data in the display of the parking position for specifying the destination. The display prioritized according to the overall parking time can be performed. In addition, since the sum of past parking times at the same parking position is directly recorded as parking history data, prioritization based on the accumulated parking time should be performed more quickly than when the sum itself is not recorded. Can do.

In the above embodiment, the parking history data recording program 100 and the parking history destination specifying program 200 correspond to the programs in the claims. Moreover, the control circuit 19 functions as a recording unit by executing the parking history data recording program 100. The control circuit 19 functions as a display control unit by executing step 220 of the parking history destination specifying program 200, and functions as a destination specifying unit by executing step 240.

  For example, the parking history data and the variable Tp are not limited to the HDD, but any storage medium such as a flash memory, a backup RAM, or the like that can keep stored data even when the vehicle navigation device 1 is stopped. It may be anything.

  Further, the control circuit 19 may additionally record the parking time at each parking opportunity in the entry of the parking history data in step 145 of the parking history data recording program 100. By doing so, each entry of the parking history data is listed in a plurality of parking times at a plurality of parking opportunities. In this case, the control circuit 19 calculates the sum of the parking time in each entry in step 220 of the parking history destination specifying program 200, and performs sorting based on the calculated value.
