  Each component and function described above is achieved by the CPU 21 executing a program loaded into the RAM 22 or ROM 23.

  [Description of Operation] Next, the operation of the in-vehicle navigation device 100 having the above-described configuration will be described.

  FIG. 6 is a flowchart showing the flow of the function activation process.

  The function activation process is a process that starts immediately after the in-vehicle navigation device 100 is activated.

  The main control unit 101 selects a target function for performing the processing after the next step (step S111).

  Specifically, functions other than the function that has been determined to be inactivated are selected from the function management table 400 stored in the storage device 3 and loaded into the RAM 22. In other words, records excluding records in which the activation status 402 is “inactive” and the confirmed status 403 is “confirmed” are loaded into the RAM 22 from the table of the function management table 400.

  Next, the activation function determination unit 103 selects a function satisfying the activation condition from the records loaded in the RAM 22 in step S111 and adds it to the activation target function list (step S112).

  Specifically, the activation function determination unit 103 reads the activation condition table 330, acquires the activation condition 332 of each record loaded into the RAM 22 in step S111, and the condition described in the activation condition 332 is It is determined whether or not the condition is satisfied, a record that can be determined to satisfy the condition described in the activation condition 332 is selected, and the function name 401 of the function indicated by the selected record is listed on the RAM 22 Add to the area. The activation function determination unit 103 performs the determination of the condition described in the activation condition 332 based on the information acquired from the vehicle state detection unit 102.

  In step S112, for example, the vehicle condition detection unit 102 calculates the travel distance by integrating the pulse acquired from the wheel speed sensor 6 and the circumference of the wheel of the host vehicle, acquires the elapsed time from the main control unit 101, The travel distance and elapsed time are transferred to the activation function determination unit 103. The activation function determination unit 103 uses the received travel distance and elapsed time of the own vehicle, for example, when the average moving speed of the own vehicle on the link is lower than 10 km / h, it is determined that the vehicle is in a traffic congestion state. If the state continues for more than 5 minutes, it is determined that the activation condition 332 that the traffic is over 5 minutes is satisfied, and the activation condition is designated in the activation condition table 330. The function name 401 of the existing detour search function is added to the activation target function list (not shown).

  Next, the function activation unit 104 activates the function identified by the function name included in the activation target function list and the function required to activate the function (step S113). .

  Specifically, the function activation unit 104 performs a setting for activating the function identified by the function name added to the activation target function list. At that time, the activation setting table 334 of the activation condition table 330 is referred to, necessary setting information is acquired, and is set in the in-vehicle navigation device 100. Further, the function activation unit 104 activates the function identified by the function name set in the necessary function 333 immediately before performing this setting.

  Taking FIG. 2 as an example, when the detour search function is activated, the automatic reroute function stored in the necessary function 333 is first activated, and then the detour search function is activated. After the activation, the function activation unit 104 requests the display processing unit 106 to display the function name of the activated function in the message display area on the display 11.

  FIG. 7 shows an example of a screen displayed on the display 11 as a result of step S113. The screen 50 is a screen that is displayed regardless of the execution of step S113, such as a route guidance screen. The display 11 displays a message display area 501 by partially overlapping the screen.

  Specifically, in step S113, the function activation unit 104 causes the display processing unit 106 to display the message area 501 in a superimposed manner, and the content of the message, for example, “<!> Detour search function. Instructed to be displayed. Upon receiving the instruction, the display processing unit 106 configures the screen of FIG. 7 based on the instruction and causes the display 11 to display the screen.

  By performing the above steps S111 to S113, each function can be activated.

  Of the above-described step S113, the process for displaying the screen of FIG. 7 is provided with a separate process start condition, when the vehicle is stopped next time with the side brakes pulled or the engine of the vehicle is stopped. The process may be started at another timing such as when the vehicle-mounted navigation device 100 is activated next time.

  Specifically, in step S113, the process start condition determination process is performed immediately before the process of displaying the screen shown in FIG. 7, and only when the determination to start the process is obtained as a result of the determination process, FIG. The process for displaying the screen shown in Fig. 2 is started. In the process start condition determination process, the function activation unit 104 inquires of the main control unit 101 whether or not the side brake is applied, and obtains a response indicating that the side brake is applied. In the case, or when the main control unit 101 is inquired as to whether or not the engine is in a stopped state and a response indicating that the engine is in a stopped state is obtained, it is determined to start the processing.

  Next, a process for confirming with the user whether or not it is possible to set the function to continue to be activated for the activated function will be described.

  The main control unit 101 selects a target to be processed after the next step (step S114).

  Specifically, among the activated functions, a function that is not determined to be activated in the future is selected from the function management table 400 stored in the storage device 3 and loaded into the RAM 22. That is, from the table of the function management table 400, a record in which the activation status 402 is “active” and the confirmed status 403 is “unconfirmed” is loaded into the RAM 22.

  Next, the activation function determination unit 103 selects a record satisfying the condition for performing continuation confirmation from the records loaded in the RAM 22 in step S114 and adds it to the continuation confirmation target function list (not shown) (step S115). ).

  Specifically, the activation function determination unit 103 reads the activation condition table 330, acquires each continuation confirmation condition 335 from the records loaded into the RAM 22 in step S114, and is described in the continuation confirmation condition 335. Select a record that satisfies the specified conditions and add it to the function list for continuous confirmation. The activation function determination unit 103 determines the condition described in the continuation confirmation condition 335 based on the information acquired from the vehicle state detection unit 102.

  For example, the vehicle state detection unit 102 calculates the travel distance by integrating the pulse acquired from the wheel speed sensor 6 and the circumference of the wheel of the host vehicle, acquires the elapsed time from the main control unit 101, and calculates the travel distance and the elapsed time. The time is transferred to the activation function determination unit 103. The activation function determination unit 103 uses the received traveling distance and elapsed time of the own vehicle, for example, the average moving speed of the own vehicle that is in a state of traffic congestion on the link exceeds 8 km / h, and a separate beacon If it can be determined from the road conditions acquired from the receiving device 9 that the link to which the current position of the vehicle belongs is not in a state indicating traffic jam, it is determined that the link indicating the traffic jam has been passed and continuation confirmation that the traffic link has been passed It is determined that the condition 335 is satisfied, and the function name 331 of the detour search function specifying the condition in the activation condition table 330 is added to the continuation confirmation target function list.

  Next, the function activation unit 104 performs a display requesting the user to determine whether or not to continuously activate the function identified by the function name included in the continuation confirmation target function list, and the user Is confirmed and an instruction is acquired (step S116).

  Specifically, the function activation unit 104 displays, on the display 11, a dialog asking whether or not to continue using the function for each of the function list to be continuously confirmed via the display processing unit 106. Let The user's selection input input by the voice input / output device 4, the input device 5, the touch input detection device 12, or the like is received via the input receiving unit 105.

  FIG. 8 is an example of a screen displayed on the display 11 in step S116.

  The screen 50 is a screen that is displayed regardless of the execution of step S116, such as a route guidance screen. The display 11 displays a dialog display area 511 so as to partially overlap the screen.

  Specifically, in step S116, the function activation unit 104 causes the display processing unit 106 to superimpose the dialog display area 511, and the content of the dialog, for example, “<! "The search function was enabled, but will it be enabled in the future?" And so on, and a button area 512 for the user to input an acknowledgment and a negative response to this dialog Button area 513 and a button area 514 for displaying a description of the function are instructed to be displayed.

  Upon receiving the instruction, the display processing unit 106 configures the screen of FIG. 8 based on the instruction and causes the display 11 to display the screen.

  When the main control unit 101 detects an input to select the button area 514 for displaying the description of the function on the screen shown in FIG. 8, the main control unit 101 performs electronic functions for explaining the function from the storage device 3. Manual data 404 is acquired and displayed on the display 11.

  FIG. 9 is a display example of the manual data 404 displayed on the display 11 in this way.

  The screen 50 is a screen that is displayed regardless of the display of the manual data 404, such as a route guidance screen. A manual data display area 521 is displayed partially overlapping the screen.

The main control unit 101 causes the display processing unit 106 to superimpose and display the manual data display area 521, and the contents of the manual data 404, for example, “What is a detour search function? This function searches and guides the route that bypasses the traffic jam route based on VICS (registered trademark) information, etc. To enable this function manually, go to Main Menu → Navigation Settings Select Menu → Route Search Menu → Detour Search. Note that the automatic reroute function must be enabled. ”And for displaying this manual data 404 The user instructs to display a button area 522 for inputting that the user ends browsing and returns to the original display dialog.

  Upon receiving the instruction, the display processing unit 106 configures the screen of FIG. 9 based on the instruction and causes the display 11 to display the screen.

  FIG. 10 is another example of a screen displayed on the display 11 in step S116.

  The dialog display area 515 has the same role as the dialog display area 511 shown in FIG. 8, but the display content is different from the dialog display area 511.

  In step S116, the function activation unit 104 causes the display processing unit 106 to superimpose the dialog display area 515 on the screen, and the content of the dialog, for example, “<! The button area 512 for the user to input an affirmative response and the button area 513 for the user to input a negative response to this dialog are displayed. And an area 516 for displaying the description of the function.

  Note that the description of the function uses the function activation unit 104 that has acquired the electronic manual data 404 from the storage device 3.

  Next, when the user's selection input received in step S116 is an affirmative continuation (eg, “Yes”), the function activation unit 104 determines the confirmation status for the function record in the function management table 400. The fact that it is confirmed is stored in the column 403 (step S117).

  If the user's selection input received in step S116 is one that denies continuous use (eg, “No”), the function activation unit 104 determines the confirmation status 403 for the function record in the function management table 400. The fact that it is confirmed is stored in the column, and the activated function is deactivated (step S118).

  By carrying out the above steps S114 to S118, it becomes possible to confirm the intention to continue activation of each function.

  Finally, the main control unit 101 accesses the function management table 400 after performing the above steps S111 to S118, and confirms that all the functions are stored as confirmed in the confirmed status 403. End. If not confirmed, the process returns to step S111, and the process is performed again from step S111 (step S119).

  The configuration and operation of the embodiment of the present invention have been described above.

  According to the above-described embodiment of the present invention, the setting is easily changed so that the user can use the function without knowing the setting operation necessary for using the function for which the user does not perform the use setting. Can be activated, and the setting can be changed to continuously use the function.

  By the way, in the said embodiment, in step S116, the function activation part 104 asks whether it uses the said function continuously via the display process part 106 about each of the above-mentioned continuous confirmation object function list. The dialog display area 511 is displayed on the display 11.

  However, since it is assumed that the user is usually a driver, the function activation unit 104 refrains from displaying the dialog display area 511 while the user continues driving, and then signals, etc. The processing may be suspended until the vehicle stops at the vehicle, and after confirming the stop through the vehicle state detection unit 102, the dialog display area 511 may be displayed on the display 11 to continue the processing.

  Specifically, immediately before step S116, that is, at the end of the process of step S115, the activation function determination unit 103 acquires the travel speed from the vehicle state detection unit 102, and performs the process until the travel speed reaches 0 km / h. Let it sleep. In step S116, after confirming that the traveling speed obtained from the vehicle state detection unit 102 is 0 km / h, the subsequent processing is started.

  Alternatively, the function activation unit 104 pauses the process until the next start-up of the navigation device, displays the dialog display area 511 on the display 11 immediately after the next start-up of the navigation device, and continues the process. Also good.

  Specifically, immediately before step S116, that is, at the end of the process of step S115, the activation function determination unit 103 registers to restart the process from step S116 following the activation process of the in-vehicle navigation device 100. To finish the function activation process.

  Next, when the in-vehicle navigation device 100 is activated, the process is resumed from step S116 of the function activation process, and the registration that is resumed at the end of the activation process of the in-vehicle navigation device 100 is released at the end of step S116. Take the realization method.

  These modifications allow the user to consider continuation while the vehicle is stable.

  Moreover, although the example which applied this invention to the vehicle-mounted navigation apparatus was demonstrated, this invention is applicable also to navigation apparatuses other than vehicle-mounted.
