  Next, functions of the parking pattern storage unit 14, the vehicle operation storage unit 15, the parking determination unit 16, and the service providing unit 17 which are features of the car navigation apparatus of the present invention will be described. First, the function of automatically determining that the vehicle is parked when the vehicle is parked at a place other than the destination, as described in “Problems to be Solved by the Invention” will be described.

The concept and procedure for automatic parking determination are as follows.
Procedure 1: A parking pattern in which a specific operation performed by the vehicle before parking is expressed in time series is registered (stored) in the parking pattern storage unit 14 in advance.
Procedure 2: When the vehicle moves, its operation is judged and classified into a predetermined classification, and the classified operation is registered (stored) in the vehicle operation storage means 15 in time series.
Procedure 3: When the vehicle stops, whether the time series pattern of the pre-stop operation stored in the vehicle operation storage unit 15 matches any of the parking patterns registered in the parking pattern storage unit 14 This is determined by the parking determination means 16. If a matching parking pattern exists, it is determined that the vehicle is parked.

  As shown in FIG. 3, the operation patterns peculiar to the vehicle before parking in the procedure 1 are classified into eight types described in the operation name column corresponding to the abbreviations A to H, and time series of the classified operations Register and store as This registered pattern is called a parking pattern. The judgment conditions for the operation of each classification are described in the operation judgment condition column in the figure. V in the “speed” condition column represents the vehicle speed detected by the vehicle speed sensor 3. The vehicle speed is detected as the same positive sign value in both forward and reverse directions. Vth is a predetermined value. When V ≦ Vth, that is, when the detection value V of the vehicle speed sensor 3 is equal to or less than the predetermined value Vth, the vehicle is considered to be in a stopped state. When V> Vth, it is considered that the vehicle is moving forward (including turning) or moving backward (including turning).

  Whether the vehicle is moving forward or backward is determined by a signal from the reverse signal sensor 5. The travel distance L is obtained by integrating signals from the vehicle speed sensor 3. When the moving distance L during the straight forward operation becomes equal to or greater than the predetermined value Lth, it is considered that the vehicle has advanced a long distance. If it is less than Lth, it is considered as a short distance advance. If the absolute value | θ | of the output signal θ of the angular velocity sensor 3 is equal to or less than the predetermined value θth when V> Vth, it is considered that the vehicle is in a straight forward or straight forward state. When the value of θ is larger than the predetermined value θth, the vehicle is considered to be in a right turn state. When the value of θ is smaller than the predetermined value −θth, the vehicle is considered to be in a left turn state.

  If the operations are classified under such a determination condition, all the self-powered behaviors of the vehicle can be expressed as a time-series connection of any of the eight types of operations A to H. In the procedure 1, a specific operation pattern before the vehicle is parked is extracted according to the operation classification, and is registered in the parking pattern storage unit 14 as a parking pattern. Next, some examples of such parking patterns will be described.

  FIG. 4 shows an example of operation when the vehicle is parked in parallel by shifting the width to the left while moving backward. A series of operations of the vehicle in this case can be divided into six operations 1 to 6 shown in the figure. Each operation becomes A, G, F, H, F, A as shown in FIG. These series of operations are represented in time series as shown in (1) of FIG. That is, the pre-parking operation in which the vehicle is parked in parallel while moving backward as shown in FIG. 4 can be expressed by the parking pattern (1) in FIG.

  FIG. 6 is an operation example when the width-shifting direction is the right side opposite to FIG. 4, and the parking pattern in this case is expressed as (2) in FIG. 5. FIG. 7 is an example of parallel parking operation when there is no operation of operation number 5 and F (straight forward and backward) in FIG. The parking pattern in this case is expressed as (3) in FIG. Similarly, FIG. 8 is an example of parallel parking operation when there is no operation of operation number 5, F (straight forward and backward) in FIG. 6, and the parking pattern in this case is expressed as (4) in FIG. The

  In addition to the parallel parking operation, there is also an operation of moving forward and parking after moving back and forth. FIG. 9 shows a case where a straight forward short distance forward (C) operation is performed after the series of operations shown in FIG. 7 to stop (A). The parking pattern in this case is expressed as (5) in FIG. The parking pattern when the width-shifting direction is on the right side is expressed as (6) in FIG. FIG. 10 shows a case in which a straight forward short distance forward (C) operation is performed after the series of operations shown in FIG. 4 to stop (A). The parking pattern in this case is expressed as (7) in FIG. When the width-shifting direction is opposite, it is as shown in (8) of FIG. As described above, at least eight types of parking patterns shown in FIG. 5 are conceivable as operations before parallel parking. Furthermore, a parking pattern in which these are modified is also conceivable.

  FIG. 11 and FIG. 12 are operation examples when parking in a row. FIG. 11A shows a case where the vehicle is turned forward and the vehicle is parked forward while being widened to the right, and the parking pattern in this case is expressed as shown in FIG. 11B. (A) of FIG. 12 is a case where the width is shifted to the left opposite to (a) of FIG. 11, and the parking pattern in that case is expressed as shown in (b) of FIG. Many other variations of the parking pattern for row parking are possible.

In the procedure 1, all the unique operations before parking that can be considered in this way are extracted, and their time-series expressions are registered (stored) in the parking pattern storage unit 14 as parking patterns.
Next, in step 2, when the vehicle actually moves, its operation is classified into eight types shown in FIG. 3, and the classified results are registered (stored) in the vehicle operation storage means 15 in time series. The processing flow will be described with reference to FIGS.

  Prior to the start of processing, a time-series storage area is stored in the memory of the vehicle operation storage means 15 for storing the operation when the vehicle actually moves in time series. In the first step S1, it is determined whether or not the vehicle is in a “straight forward movement” operation. This "straight forward advance" determination condition is an arbitrary movement distance condition in the "B" (straight forward long distance forward) or "C" (straight forward short distance forward) determination conditions in the motion classification of FIG. It is.

  If the condition is satisfied, the process proceeds to step S2. In step S2 and the next step S3, the forward distance L during the “straight forward advance” operation is measured. The forward distance L is obtained by integrating the detection signal of the vehicle speed sensor 4. If it is determined in step S3 that the "straight forward advance" condition is not satisfied, the process proceeds to step S4. In step S4, it is determined whether or not the value of the movement distance L measured in steps S2 and S3 is equal to or greater than a predetermined value Lth. If it is equal to or greater than the predetermined value Lth, the process proceeds to step S5, where it is considered that the “straight forward long distance advance” operation has been performed, and the abbreviated name “B” of the operation is set in the time series storage area reserved first. Add to the tail. If the predetermined value Lth has not been reached, the process proceeds to step S6, where it is considered that the “straight forward short distance advance” operation has been performed, and the abbreviation “C” of the operation is added to the end of the time series. And both return to step S1.

If it is not determined as “straight forward” in step S1, the process proceeds to step S7. In step S7, it is determined whether or not a “right turn forward” operation is being performed. This determination condition is that all the operation determination conditions for “forward in a right turn” of “D” in FIG. 3 are satisfied. If the condition is satisfied, the process proceeds to step S8.
In step S8, it is checked whether or not the operation recorded at the end of the time-series storage area is “D” (right turn forward). If it is “D” (forward to the right turn), the same “D” (forward turn to the right turn) operation is continued, and the process returns to step S1 without doing anything. If the action recorded at the end is not “D” (right turn forward), the process proceeds to step S9, “D” (right turn forward) is added to the end of the time series, and step S1 is executed. Return to.

If it is determined in step S7 that the "right turn forward" operation is not being performed, the process proceeds to step S10. In step S10, it is determined whether or not a “left turn forward” operation is being performed. This determination condition is that all the operation determination conditions of “Left turn forward” of “E” in FIG. 3 are satisfied. If the condition is satisfied, the process proceeds to step S11.
In step S11, it is checked whether or not the action recorded at the end of the time-series storage area is “E” (left turn forward). If it is “E” (left turn advance), the same “E” (left turn advance) operation is continued, and the process returns to step S1 without doing anything. If the action recorded at the end is not “E” (left turn advance), the process proceeds to step S12, “E” (left turn advance) is added to the end of the time series, and the process returns to step S1. .

If it is determined in step S10 that the "left turn forward" operation is not being performed, the process proceeds to step S13 in FIG. In step S13, it is determined whether or not a "straight forward and backward" operation is being performed. This determination condition is that all the operation determination conditions of “straight forward / reverse” of “F” in FIG. 3 are satisfied. If the condition is satisfied, the process proceeds to step S14.
In step S14, it is checked whether or not the operation recorded at the end of the time series storage area is "F" (straight forward and backward). If it is “F” (straight forward / reverse), the same “F” (straight forward / reverse) operation is continued, and the process returns to step S1 without doing anything. If the motion recorded at the end is not “F” (straight-back), the process proceeds to step S15, “F” (straight-back) is added to the end of the time series, and the process returns to step S1.

If it is determined in step S13 that the "straight forward / reverse" operation is not being performed, the process proceeds to step S16. In step S <b> 16, it is determined whether or not a “right turn backward” operation is being performed. This determination condition is that all of the operation determination conditions for “right turn backward” of “G” in FIG. 3 are satisfied. If the condition is satisfied, the process proceeds to step S17.
In step S17, it is checked whether or not the operation recorded at the end of the time-series storage area is “G” (backward turning to the right). If it is “G” (backward turning to the right), the same “G” (backward turning to the right) is continued, and the process returns to step S1 without doing anything. If the motion recorded at the end is not “G” (backward turning to the right), the process proceeds to step S18, “G” (backward turning to the right) is added to the end of the time series, and step S1 is executed. Return to.

If it is determined in step S16 that the "right turn backward" operation is not being performed, the process proceeds to step S19. In step S19, it is determined whether or not a “left turn backward” operation is being performed. This determination condition is that all the operation determination conditions of “left turn backward” of “H” in FIG. 3 are satisfied. If the condition is satisfied, the process proceeds to step S20.
In step S20, it is checked whether or not the operation recorded at the end of the time-series storage area is “H” (left turn backward). If it is “H” (left turning backward), the same “H” (left turning backward) operation is continued, and the process returns to step S1 without doing anything. If the action recorded at the end is not “H” (left turn backward), the process proceeds to step S21, “H” (left turn reverse) is added to the end of the time series, and the process returns to step S1. .

  If it is determined in step S19 that the "turn left and backward" operation is not being performed, the process proceeds to step S22. In step S22, it is determined whether or not it is in the “stop” state. This determination condition is that the “stop” determination condition of “A” in FIG. 3 is satisfied. If the condition is not satisfied, the process returns to step S1 (normally this does not happen). If the condition is satisfied, the process proceeds to step S23.

  In step S23, it is checked whether or not the operation recorded at the end of the time series storage area is “A” (stop). If it is “A” (stop), the same “A” (stop) operation is continued, and the process returns to step S1 without doing anything. If the operation recorded at the end is not “A” (stop), the process proceeds to step S24, “A” (stop) is added to the end, and the process proceeds to step S25.

  Through the processing as described above, the actions performed by the vehicle are stored in time series in the time series storage area. FIG. 15 shows an example of a time series of operations stored by such processing. When the vehicle performs the operation shown in FIG. 15A, as shown in FIG. 15B. A long operation time series is stored in the time series storage area.

  Next, procedure 3 will be described. Step 3 is a step of determining whether or not the vehicle is parked, and is performed by the parking determination means 16. This determination is performed when the vehicle enters the “stop” state, and is performed in step S25 of the processing flow of FIG. In step S25, several to dozens of operation time series including the last “stop” of the operation time series stored in the time series storage area, for example, the operation time series of FIG. 5 (1) to (8), (b) in FIG. 11, (b) in FIG. 12, and the like are checked to see if they match any of the parking patterns. If there is a matching parking pattern, it is determined that the vehicle has parked, and if it does not match any parking pattern, it is determined that the vehicle is not parked but temporarily stopped. In the case of the operation time series of FIG. 15B, the six time series of the operation numbers 4 to 9 coincide with the parking pattern of FIG. Therefore, when it is determined as “A” (stop) in the operation number 9, it is determined that the vehicle is parked in the parking pattern of FIG. 5 (1) which is parallel parking.

In this way, the processing method described in Procedure 1, Procedure 2, and Procedure 3 automatically detects that the vehicle is parked without depending on the operation of the driver.
Next, immediately after it is automatically determined that the vehicle is parked at a place other than the destination, as described in “Problems to be solved by the invention”, various information related to the vicinity of the parking place is provided, and other services are provided. The function to provide will be described. This service provision is performed by the service provision means 17 in step S26 of FIG.

There is no limitation on the content of the service to be provided, and it is preferable to provide as many services as possible. In the present embodiment, services including the following four types are provided.
1. Guide to walking route to destination.
When it is determined that the vehicle has entered the “parking” state, the parking spot does not match the destination registered in the car navigation device in advance, but the distance between them is less than a predetermined value and can be moved on foot. If it is a distance, the walking route from the parking spot to the destination is displayed on the display device 8 as a map or schematic diagram and provided to the driver. A map or schematic diagram representing a walking route is displayed using data stored in the map data storage means 18. If such a service is provided, the driver can reach the destination in a short time without hesitation.

2. Providing information about various facilities around the parking spot.
When it is determined that the vehicle has entered the “parking” state, the name of the store around the parking spot, the handling item, the telephone number, the opening time, the closing time, etc. are displayed on the display device 8 in a list format and the driver To provide. When the driver selects a store on the list, the walking route from the parking spot to the store is displayed on the display device 8 as a map or a schematic diagram. Detailed information such as the store to be provided is provided using information stored in the map data storage means 18, the service data storage means 20, the position calculation means 19 and the like. If such a service is provided, the driver can quickly find and use a necessary store.

3. Provision of a service that automatically sends parking point information to a specific email address.
When it is determined that the vehicle has entered the “parking” state, an e-mail describing information on the parking spot (address, parking location, coordinates, etc.) is automatically transmitted to a pre-registered mail address. If the e-mail address of the mobile phone (mobile terminal) possessed by the driver is registered as the e-mail address, it can be used as a clue to search for a vehicle when the parking position is forgotten after getting off. It can also be applied to a system for managing the operation status of taxis and delivery trucks (ascertaining parking locations). The coordinates of the parking spot are calculated by the position calculation means 19 based on a signal from the GPS receiver 2. The address of the parking spot and the parking place are specified by the position calculation means 19 by a process of collating the coordinates of the parking spot with the map data stored in the map data storage means 18.
4). Providing a service that automatically sends a signal to cancel a call reception disabled state to a specific mobile phone.

  When it is determined that the vehicle has entered the “parking” state, a signal for canceling an incoming call impossible state (drive mode, etc.) is issued to a specific mobile phone, for example, a mobile phone (mobile terminal) possessed by the driver. , For example, using Bluetooth (trademark name) or other short-range wireless transmission. If such a service is provided, it is possible to prevent the incoming call disabled state from continuing due to forgetting to cancel the incoming call disabled state.

(Modified embodiment)
The above-described embodiment can be modified as follows. In the above-described embodiment, the operation of the vehicle is classified into the eight types shown in FIG. These eight types of classifications are cases where the vehicle operates on its own. As another operation, the vehicle may move by other force. As a specific example, there is a movement in which the vehicle is rotated in a state where the vehicle is placed on a turntable installed in front of the parking tower or the like. Since the movement on the turntable, that is, the turning operation in the stopped state is also useful for the parking determination, an embodiment in which classification is performed in nine types in addition to the classification of the vehicle operation is conceivable.

  FIG. 16 shows classification abbreviations, motion names, and motion determination conditions for the turning motion in the stopped state. The operation determination condition is that two conditions are satisfied: the vehicle speed V is equal to or less than the predetermined value Vth, that is, the vehicle is stopped, and the absolute value | θ | of the angular velocity of the vehicle is equal to or greater than the predetermined value θth2. It is. FIG. 17A shows an operation example in the case of entering the parking tower and performing parking after performing such a “stop state turning” operation on the turntable. The parking pattern in this case is expressed as (1) or (2) in FIG.

  In the above-described embodiment in which “stop state turning” is not included in the classification, it is determined whether or not the vehicle has entered the “parking” state when the vehicle is determined to be in the “stop” state. On the other hand, in the embodiment in which “stop turning” is added to the operation classification, it is determined that the state is close to “parking” at the time when it is determined as “stop turning”, and the various services described above are performed at that stage. Preferably it is provided. This is because it is too late to determine the “parking” state and provide the service when the parking tower is entered and stopped after the “stop-turning” operation on the turntable is completed.

  In order to make such a determination, “I” (stop state turning) is stored at the end of the operation time series in the time series storage area, as in the parking pattern shown in FIG. 17B (1). The above-mentioned various services are provided. Therefore, when classifying motions into nine types including “I” (stop state turning), either “A” (stop) or “I” (stop state turning) is stored in the operation time series. At this point, the service is determined to be in the “parking” state.

  By adding “I” (stop state turning) to the classification in this way, automatic parking determination when parking in a parking tower or the like can be performed more reliably, and at the time of providing the service described above There is an advantage that speeds up.
