The map storage device 11 stores a plurality of map data such as a Western European version (WEU), an Eastern European version (EEU), and a Russian version (RU) in a map storage medium. By performing the license setting, it is possible to use specific map data from among a plurality of map data. The map storage medium of the map storage device 11 also stores map data unique information (Update.inf). The map data unique information includes information indicating the cover area and version number information such as the Western European version (WEU), the Eastern European version (EEU), and the Russian version (RU).

  The display device 12 has a display such as a liquid crystal, and displays an image corresponding to the video signal input from the control device 13 on the display.

  The control device 13 is configured as a computer including a CPU 13a, a DRAM 13b as a volatile storage medium, a ROM 13c, a flash memory 13d as a nonvolatile storage medium, and an external interface 13e. The CPU 13a, DRAM 13b, ROM 13c, flash memory 13d, and external interface 13e are connected by an internal bus (not shown).

  The ROM 13c stores navigation ECU specific information (VNcode). The data stored in the flash memory 13d is held regardless of the operation state of the navigation device 1, but the data stored in the DRAM 13b is in an off state because the vehicle ignition switch is turned off. When it becomes, it is deleted.

  A vehicle signal is input to the control device 13 from each unit mounted on the vehicle. The vehicle signal includes information for specifying the current position input from a vehicle speed sensor, a gyroscope, a geomagnetic sensor, etc., vehicle specific information (VIN code) input from an engine ECU (not shown), and the like. The vehicle specific information (VIN code) includes the vehicle manufacturing year, body type code, manufacturing number, and the like.

  The external interface 13e is an interface for communicating with each device connected to the in-vehicle LAN 2. The external interface 13e is connected to a communication terminal 3, an audio device 4 and the like for performing license setting and the like via the in-vehicle LAN 2.

  The navigation apparatus 1 performs license setting (official license setting) for permitting use of map data before use. In the present embodiment, an operator operates the communication terminal 3 to set an official license at the time of an assembly process to a vehicle at an automobile manufacturer, an automobile dealer, an automobile goods dealer, or the like.

  In addition, in a single inspection of a navigation device before shipping to an automobile manufacturer or the like, a map is displayed and stored in a map storage medium by temporarily setting a license (temporary license setting) using the communication terminal 3. It is possible to check the normality of map data. In the following, processing for official license setting and temporary license setting will be described.

  First, the official license setting process will be described with reference to FIG. It is assumed that the vehicle main navigation device 1 is assembled and the communication terminal 3 is connected to the navigation device 1. When the ignition switch of the vehicle is turned on in response to the operator's operation, the navigation device 1 is activated and is in an operating state, and the control device 13 performs the process shown in FIG.

  First, it is determined whether there is an official license instruction (S100). Specifically, it is determined whether or not an official license setting instruction (official setting command) for instructing an official license setting is input from the communication terminal 3 in accordance with the operation of the operator.

  Here, when the official license setting instruction is not input, the determination in S100 is NO, and the determination in S100 is repeatedly performed.

  When an official license setting instruction is input from the communication terminal 3 in accordance with the operator's operation, a license key is then generated (S102). Specifically, information for generating a license key is acquired according to the official license setting instruction, and a license key is generated using the acquired information for generating the license key. In this embodiment, a license key is generated from three pieces of unique information: vehicle unique information (VIN code), map data unique information (Update.inf), and navigation ECU unique information (VNcode). That is, when an instruction for setting an official license is input, a vehicle code (VIN code) is obtained from an engine ECU or the like mounted on the vehicle, map data unique information (Update.inf) is read from the map storage medium, and read from the ROM 13c. The navigation ECU specific information (VNcode) is read, and a license key is generated according to a predetermined rule using three pieces of information. This technique for generating a license key is a well-known technique.

  Next, the generated license key is stored in the flash memory 13d (S104). Specifically, the generated license key is stored in a predetermined specific area of the flash memory 13d, and this process ends. In order to prevent the license from being licensed for the map data once licensed, license key change instructions and erase instructions stored in the flash memory 13d are not accepted at all.

  Next, map data use permission determination processing by the control device 13 will be described. FIG. 3 shows a flowchart of the map data use permission determination process. The control device 13 performs the processing shown in FIG. 3 when the navigation device 1 is activated, when the license key is stored in the flash memory 13d and when the license key is stored in the DRAM 13b.

  First, the license key is read from the flash memory 13d and stored in the DRAM 13b (S200). That is, the license key stored in the specific area of the flash memory 13d is read and stored in the specific area of the DRAM 13b. If no license key is stored in the flash memory 13d, nothing is stored in a specific area of the DRAM 13b.

  Next, based on whether or not the license key is stored in the DRAM 13b, it is determined whether or not to enable the map display function of the map data specified by the license key (S202). In this embodiment, it is determined whether or not to enable the map display function of the map data specified by the license key based on whether or not any license key is stored in the specific area of the DRAM 13b.

  When the official license setting has been completed normally, the license key read from the flash memory 13d is stored in the DRAM 13b. Therefore, the determination in S202 is YES, and the map display function of the map data specified by the license key is set. It is activated (S204). By this validation, the use of the map data is permitted, and the map display by the map data specified by the license key becomes possible. Therefore, a map or the like around the vehicle position can be displayed on the display of the display device 12 in accordance with a user operation.

  However, if the license key is not stored in the flash memory 13d because the official license setting has not been performed, or if the license key is not stored in the flash memory 13d because the official license setting has not been completed normally, the determination in S202 is NO, The map display function based on the map data is disabled (S206). In this case, since the use of the map data is not permitted, the map cannot be displayed.

  Next, the temporary license setting process will be described with reference to FIG. This processing is performed in a single inspection of the navigation device before shipping to an automobile manufacturer or the like. When the communication terminal 3 is connected to the navigation device 1 by an operator and the navigation device 1 is in an operating state, the control device 13 performs the process shown in FIG.

  First, it is determined whether or not there is a temporary license instruction (S300). Specifically, it is determined whether or not a temporary license setting instruction (temporary setting command) for instructing temporary setting of a license is input from the communication terminal 3 in accordance with the operation of the operator.

  Here, if the temporary license setting instruction is not input, the determination in S300 is NO, and the determination in S300 is repeated.

  Then, when a temporary license setting instruction is input from the communication terminal 3 in accordance with the operator's operation, information for generating a license key is acquired and the acquired license key is generated as in S102 of FIG. A license key is generated using the information for performing the operation (S302).

  Next, the generated license key is stored in the DRAM 13b (S304), and this process ends.

  When the license key is stored in the DRAM 13b, the map data use permission determination process shown in FIG. 3 is performed, and the map display function based on the map data specified by the license key is activated and map display is possible. It becomes. In this way, the normality of the map data stored in the map storage medium is confirmed by displaying the map.

  As shown in FIG. 5, in the above-described official license setting process, when a license key is generated according to an official setting instruction input from the communication terminal 3, the generated license key is stored in the flash memory 13d. In the map data use permission determination process, the license key is read from the flash memory 13d and stored in the DRAM 13b, and the map display of the map data specified by the license key based on whether or not the license key is stored in the DRAM 13b. A determination is made whether to enable the function.

  Further, in the single inspection of the navigation device before shipping to an automobile manufacturer or the like, the license key is not stored in the flash memory 13d, and the temporary setting instruction input from the communication terminal 3 as shown in FIG. When the license key is generated, the generated license key is stored not in the flash memory 13d but in the DRAM 13b. When the license key is stored in the DRAM 13b as described above, the map display function based on the map data specified by the license key is validated in the map data use permission determination process, and the map display is enabled. In this way, it is possible to display the map and confirm the normality of the map data stored in the map storage medium.

  According to the configuration described above, when a map data temporary setting instruction for temporarily setting a license among a plurality of map data is input, a license key corresponding to the temporary setting instruction is stored in the volatile storage medium. Since the map display function of the map data specified by the license key is enabled based on whether the license key is stored in the volatile storage medium, the license key is stored in the non-volatile state even before the official license is set. The normality of the map data stored in the map storage medium can be confirmed by displaying the map without storing it in the storage medium. In addition, when a temporary setting instruction is input, a license key corresponding to the temporary setting instruction is stored in the volatile storage medium. When the apparatus is stopped, the license key is stored in the volatile storage medium. Since the license key is completely erased, it is possible to prevent the map display from being possible without setting the license after shipment to an automobile manufacturer or the like.

  In the configuration described above, information for generating a license key is acquired in response to an input of a temporary setting instruction, and the license key is generated using the acquired information for generating the license key. The person can display the map without obtaining a regular license and confirm the normality of the map data stored in the map storage medium.

  In the above configuration, the license setting is performed using a communication terminal connected to the external interface, and temporary license setting cannot be performed without using this communication terminal. By managing the terminal so that it is not used, it is possible to prevent a temporary license from being set by a general user.

  In addition, this invention is not limited to the said embodiment, Based on the meaning of this invention, it can implement with a various form.

  For example, in the above embodiment, the configuration is shown in which the operator operates the communication terminal 3 to set the official license during the assembly process to the vehicle in an automobile manufacturer or the like. The license key acquired by the license purchase procedure may be input according to the license key setting screen to set the official license, and the license key may be stored in the flash memory 13d. Further, at the time of the assembly process to the vehicle in an automobile manufacturer or the like, the license key acquired by the license purchase procedure is input according to the license key setting screen to set the official license, and the license key is stored in the flash memory 13d. May be. In this way, by adopting a configuration in which the license key is directly input, it is possible to eliminate the process of acquiring information for generating the license key and generating the license key.

The correspondence relationship between the configuration of the above embodiment and the configuration of the claims will be described. S100 to S104 correspond to the official license setting unit, S200 corresponds to the license key storage unit, and S202 and S204 display the map. Corresponding to function enabling means, S300 to S304 correspond to temporary license setting means,
S302 corresponds to license key generation means, and S304 corresponds to license key storage means.
