Description

The present invention relates to a control system, an in-vehicle device, and a program for storing information regarding a target object in a storage medium used in an in-vehicle device.

2. Description of the Related Art In-vehicle devices are known that specify positional information between a target object and the own vehicle, and notify a driver of information regarding the specified positional relationship. Examples of in-vehicle devices include radar detectors. Examples of targets include devices that measure vehicle speed. Target objects are often installed in dangerous locations where traffic accidents are likely to occur. Therefore, the in-vehicle device can encourage the driver to drive safely in areas where traffic accidents are likely to occur, for example by notifying the driver of the approach to a target object. In this way, informing the driver of the positional relationship between the target object and the own vehicle contributes to the driver's safe driving.

In an on-vehicle device, the freshness and accuracy of position information of a target object are important factors. In other words, if the location information of the target object is old, the driver may be notified at a location where the target object has already been removed, or the location information of that location may be updated even though there is a newly installed target object. Because there is no information, notifications may not be sent, reducing reliability. Therefore, in a normal vehicle-mounted device, it is possible to update the position information of the target object even after purchase.

A conventional method of updating location information of a target object is as follows. The target object's location information is stored in an external non-volatile memory such as an SD card. The in-vehicle device refers to the position information stored in the set external non-volatile memory and notifies the driver. When updating location information, the driver removes the external nonvolatile memory from the in-vehicle device and sets it in an information terminal such as a PC. The information terminal can update the position information stored in the external non-volatile memory to the latest information.

Further, Patent Document 1 discloses a technique for acquiring new position information updated in another vehicle-mounted device by receiving location information wirelessly transmitted from another vehicle-mounted device and storing it in a memory.

JP2009-266057A

The device described in Patent Document 1 requires a new communication device for performing wireless communication between in-vehicle devices, so a method of updating location information using an information terminal is usually adopted. Here, the format and content of the position information stored in the external non-volatile memory must correspond to the type of in-vehicle device. This is because the format and contents of the position information stored in the external nonvolatile memory differ depending on the type of in-vehicle device. If location information corresponding to a different type of in-vehicle device is stored in an external nonvolatile memory, the in-vehicle device cannot use the location information and cannot notify the driver. Therefore, when updating location information via an information terminal, it is necessary to specify to the information terminal the type of in-vehicle device in which the external nonvolatile memory is used. However, since drivers often do not recognize the type of in-vehicle device they are using, there is a problem in that they have to go out of their way to confirm the type of in-vehicle device when updating location information, which is cumbersome.

An object of the present invention is to provide a control system, an in-vehicle device, and a program that can reliably store information that can be used in different types of in-vehicle devices in a storage medium.

The control system according to the first aspect of the present invention is configured such that information on the target object is stored in advance on a storage medium that is used by an on-vehicle device that issues a notification to the driver based on the positional relationship between the target object and the vehicle. The present invention is characterized in that control is performed to read type information of the in-vehicle device read, obtain information on the target object corresponding to the read type information of the in-vehicle device, and store it in the storage medium.

According to the first aspect, a user can store target object information that can be used in an in-vehicle device in a storage medium without performing an operation for specifying target object information that can be used in an in-vehicle device on a control system. Can be done. The in-vehicle device can reliably perform notification regarding the target object by referring to the storage medium in which information about the target object is stored. For example, the target object information may include position information of the target object. This is because by including the position information in the target object information, the in-vehicle device can perform notification based on the positional relationship with the vehicle. Since the user does not need to know in advance the type information of the in-vehicle device as the type of target information that can be used in the in-vehicle device, the user can quickly and easily update the target information stored in the storage medium. It can be carried out.

In the first aspect, it is preferable to include an in-vehicle device that writes type information of its own in-vehicle device onto the recording medium when the type information of the in-vehicle device is not stored on the storage medium. When a general-purpose storage medium is used, the storage medium usually does not store type information of the in-vehicle device, so the user needs to store the type information of the in-vehicle device to be used in the storage medium. When the type information of the in-vehicle device is manually stored, the user has to confirm the type of the in-vehicle device, which is cumbersome. Furthermore, if incorrect type information of the in-vehicle device is stored in the storage medium, the in-vehicle device will not be able to properly notify the driver. In contrast, in the present invention, since the in-vehicle device directly stores the type information of the in-vehicle device in the storage medium, the type information of the in-vehicle device is stored accurately and reliably. Therefore, the control system can reliably store target object information that can be used in the vehicle-mounted device on the storage medium. The in-vehicle device can reliably notify the driver by referring to the storage medium.

In the first aspect, as the type information of the vehicle-mounted device, it is preferable to use the type of target information that can be used by the vehicle-mounted device. Even if in-vehicle devices have the same hardware, usable target information may differ. For example, there is a case where the versions of firmware that drive the on-vehicle devices are different. Here, by using the type of target object information that can be used in the in-vehicle device as the identification information of the in-vehicle device stored in the storage medium, if the information on the target object that can be used in the in-vehicle device with the same hardware is different. Even in this case, it is possible to reliably store target information that can be used in each in-vehicle device in the storage medium. Therefore, the in-vehicle device can reliably notify the driver by referring to the storage medium.

In the first aspect, difference information is obtained that is information about a difference between information on the target object corresponding to type information of the in-vehicle device read from the storage medium and information on the target object that has already been acquired. , preferably stored in the storage medium. For example, the amount of information on the target object may be large, such as when the information on the target object includes position information, type information on the target object, an image showing the appearance of the target object, and the like. On the other hand, since the control system stores the difference information in the storage medium, it is possible to suppress the amount of information stored in the storage medium. Therefore, the time required to store information on the storage medium can be reduced.

In the first aspect, information on the target object within a predetermined area among the information on the target object corresponding to type information of the in-vehicle device, and information on the target object within a predetermined area among the information on the target object that has already been acquired. It is preferable to obtain difference information between the information and the information and store it in the storage medium. The control system narrows down target object information based on the target object's position and stores it in a storage medium. For example, when storing information on public enforcement on a storage medium, information on public enforcement conducted in the area including the location where the vehicle is located or the area through which the vehicle passes before heading to the destination is stored on the storage medium. If so, public enforcement information corresponding to the vehicle location can be notified to the driver. Therefore, in the control system, only the difference information of the target object information corresponding to the predetermined area as described above is stored in the storage medium. This allows the control system to further reduce the amount of information stored in the storage medium.

In a first aspect, when the storage medium stores history information in which a traveling position and a traveling time of the vehicle are associated with each other, the history information stored in the storage medium is acquired, and the It is preferable to delete the history information from the storage medium. This can prevent the storage capacity from running out when the storage medium is used repeatedly in the vehicle-mounted device.

In the first aspect, control may be performed to display places visited by the vehicle in order on a map displayed on the display means based on the travel position and the travel time of the history information. Since the user can check the route of the roads actually traveled by the vehicle in chronological order, the user can more intuitively recognize his own driving history.

In the first aspect, when the position of the target object and the traveling position are close to each other, control may be performed to display an image showing the target object and a traveling speed of the vehicle at the traveling position. The control system can enhance the user's sense of reality by displaying the image of the target object and the running speed. Therefore, the user can visually check the driving history as if he/she were actually there.

In a first aspect, a first storage means is provided for storing acquired information on the target object, and among the information on the target object stored in the first storage means, the information on the target object before the travel time in the history information is provided. It is preferable that the position of the target object is determined based on information on the target object that is present and updated at a time closest to the travel time, and control is performed to display an image showing the target object. When displaying an image showing a target object, information about the target object that was installed at the time when the vehicle was traveling is referred to. As a result, an image showing the target object that was actually installed at the time the vehicle was traveling can be displayed on the map.

In the first aspect, the storage medium includes registration information that is information on the target object registered by the user, and invalidation information that instructs the user to invalidate notification based on the information on the target object. If at least one of the registration information and the invalidation information is stored in the storage medium, it is preferable to acquire at least one of the registration information and the invalidation information. The control system can effectively utilize the acquired registration information and invalidation information. For example, based on the acquired registration information and invalidation information, it is preferable to display on a display an image in which an image for specifying the target object is arranged on a map, and to have the user confirm it. This allows the user to clearly see the registered information and invalid information.

In the first aspect, when the in-vehicle device detects the target object based on radio waves output from the target object in the storage medium, the in-vehicle device detects the target object at a location where the target object is not actually installed. When detection information related to information detected in at least one of the cases where a target object is detected or the case where the vehicle-mounted device acquires vehicle status information is stored in the storage medium. It is preferable to obtain the detected information. The control system can effectively utilize the acquired detection information or time information. For example, when a target object or malfunction is detected as detection information, it is preferable to display an image on a map in which images for identifying the target object or malfunction are arranged on a map. This allows the user to clearly see the detected information.

In the first aspect, the information acquired from the storage medium is classified for each user and stored in the second storage means, and when the information is stored in the storage medium, the user who uses the storage medium is It is preferable that the user is specified based on information for specifying the user stored in the medium, and the information corresponding to the specified user is read from the second storage means and stored in the storage medium. This allows the user to repeatedly use information unique to the user in the in-vehicle device. For example, when a common in-vehicle device is jointly used by multiple users, each user preferably owns a storage medium that stores information for identifying the user. As a result, information unique to each user is stored in the storage medium, so that the in-vehicle device can operate based on information unique to each user.

In the first aspect, when the storage medium is used in the in-vehicle device, certification information certifying that the storage medium is used in the in-vehicle device is stored in the storage medium, and the certification information is stored in the storage medium. It is preferable that the information of the target object is stored in the storage medium only if it is stored. This can prevent target information from being stored in a storage medium that is not actually used by the in-vehicle device. Therefore, the security of target information can be increased, and high value-added information such as paid information can be provided only to the storage medium actually used by the in-vehicle device.

In the first aspect, the proof information is information indicating that the vehicle has traveled, and may include at least one of a traveling position and a traveling time. If the traveling position and traveling time are stored as certification information, it means that the storage medium is actually being used by the in-vehicle device. In this way, by using the traveling position and traveling time as proof information, it is possible to easily confirm that the storage medium is being used by the in-vehicle device. Furthermore, the driving position and driving time can be utilized as information indicating the driving history of the vehicle.

In a first aspect, control is performed to store setting information indicating various settings during operation of the in-vehicle device in the storage medium, and the in-vehicle device performs control to store settings information during operation based on the setting information stored in the storage medium. It is a good idea to make various settings. Thereby, various settings during operation of the in-vehicle device can be changed via the control system.

In a first aspect, a user using the storage medium is identified by information for identifying the user stored in the storage medium, and the setting information is stored for each user based on a third storage means, It is preferable that the setting information corresponding to the specified user is selected and stored in the storage medium.

Since the setting information is classified for each user, by using a storage medium that stores setting information specific to each user, the in-vehicle device can be operated with the settings of each user. For example, when a common in-vehicle device is jointly used by multiple users, each user preferably owns a storage medium that stores information for identifying the user. As a result, the user can always drive the in-vehicle device under the desired setting conditions without inputting the setting conditions when using the in-vehicle device.

In the first aspect, the setting information corresponding to a user different from the user stored in the storage medium may be read from the third storage means and stored in the storage medium. Since the information acquired from the storage medium can be stored in the storage medium in which other user IDs are stored, the information stored in the storage medium can be shared among users.

In the first aspect, when the setting information stored in the third storage means is stored in a server connected via a network, and the setting information stored in the third storage means cannot be acquired; , the setting information may be acquired from the server and stored in the storage medium. As a result, even if it becomes impossible to acquire the setting information from the third storage means due to a failure of the third storage means, the setting information can be restored by making an inquiry to the server. Therefore, it is possible to save the user the trouble of resetting the in-vehicle device.

In the first aspect, when the setting information is hierarchically organized, by guiding the user's operations on the control system in hierarchical order, the operation method desired by the user for the in-vehicle device is determined. It is preferable that the setting information necessary for operating the in-vehicle device is specified, and the specified setting information is stored in the storage medium. As a result, the user can reliably specify the setting information necessary for operating the in-vehicle device in a desired operating method by hierarchically performing input operations according to the guidance.

In the first aspect, when an inquiry regarding various settings during operation of the in-vehicle device is received, a screen for changing the setting information of the in-vehicle device corresponding to the inquiry is displayed on the display means, and the screen is It is preferable that the setting information input by the user in the displayed state is stored in the storage medium.

Since the user can specify the setting information by making an inquiry to the control system, the user can operate the in-vehicle device in a desired manner even if the user does not have detailed knowledge about the in-vehicle device. Since a screen for directly changing the setting information is displayed on the display means, the user can save the trouble of specifying the setting information by performing input operations many times to change the screen. Therefore, by quickly specifying desired setting information and storing it in a storage medium, the user can operate the in-vehicle device in a desired operating method.

In the first aspect, the information stored in the storage medium is classified into information that can be acquired by the control system and information that cannot be acquired, and the control system acquires only the information that can be acquired and the information that cannot be acquired. It is preferable not to acquire the above information.

For example, from the viewpoint of protecting user privacy, it is desirable that historical information including the vehicle's travel position and travel time not be incorporated into the control system. On the other hand, registration information and invalidation information are preferably incorporated into the control system because the latest target information can be obtained by sharing them among multiple people. In this case, it is preferable to make history information unobtainable and to enable registration information and invalidation information to be obtained. This allows the control system to capture only registration information and invalidation information. In this way, it is possible to prevent all information stored in the storage medium from being taken into the control system.

In the first aspect, it is preferable that among the acquired information on the target objects, information on the target objects within a main movement range of the vehicle is stored in the storage medium.

When the range of movement of the vehicle is specified to a certain extent, the in-vehicle device can issue notifications to the driver without any problems if information on the target object corresponding to the range of movement of the vehicle is stored in the storage medium. can. Therefore, by storing only information on the target object corresponding to the movement range of the vehicle in the storage medium, the control system can ensure that the on-vehicle device notifies the driver, and at the same time, the information stored in the storage medium The amount can be controlled.

In the first aspect, if the storage medium stores an image taken in a predetermined case by a camera installed in the vehicle, the image stored in the storage medium may be acquired. This allows images to be provided to the user in the control system.

In a first aspect, advertising information and location information are stored in the storage medium in association with each other, and the in-vehicle device is configured to: when the vehicle approaches a position indicated by the location information stored in the storage medium, It is preferable to perform control to display the advertisement information stored in the storage medium. This allows the driver to recognize advertising information regarding facilities, etc. near the vehicle. In this manner, the in-vehicle device not only provides information regarding the target object but also provides the driver with additional information based on the vehicle position, thereby enabling the driver to obtain various information while driving.

In the first aspect, control for displaying an image introducing another in-vehicle device different from the in-vehicle device in which the storage medium is used, on a display means when the usage period of the in-vehicle device has exceeded a predetermined period. It is a good idea to do this. Thereby, the control system can notify the user of the time to replace the in-vehicle device and urge the user to purchase a new in-vehicle device.

In the first aspect, when an operation instructing registration of information on the target object is received from a user, the received information on the target object may be stored in the storage medium. This allows the user to easily set the target object information by inputting the target object information using the control system and storing it in the storage medium.

In the first aspect, it is preferable to include display means having a larger display area than the display means provided in the vehicle-mounted device. In many cases, a display provided in an in-vehicle device cannot be made large due to restrictions on the overall size of the in-vehicle device. Therefore, the user cannot comfortably view or edit various information managed by the in-vehicle device. In contrast, the control system of the present invention allows for comfortable viewing and editing of various information by providing a large display with better visibility than the display means provided in the vehicle-mounted device, for example.

For example, by displaying the history information acquired from the storage medium on the display means, the user can comfortably view the driving history. For example, based on the registration information and invalidation information acquired from the storage medium, by displaying on the display means an image in which images for identifying the target object are arranged on a map, the registration information and invalidation information are shown to the user. Good visibility can be achieved. Further, for example, since the user can easily change the setting information while visually checking the display means, it becomes possible to easily operate the in-vehicle device under desired setting conditions. Further, for example, the user can easily register information on the target object by using the display means. For example, a map may be displayed on the display means and the user may select a specific point on the map. By doing this, information on the target object may be registered. In this case, it is preferable to allow the type of target object to be registered as well.

The in-vehicle device according to a second aspect of the present invention is the in-vehicle device included in the control system according to the first aspect, and when the type information of the in-vehicle device is not stored on the storage medium, The method is characterized in that device type information is written on the recording medium.

The functions of the in-vehicle device 4 of this embodiment are stored in the EEPROM 43 of the control unit 41 as firmware executed by the CPU 42 provided in the control unit 41, and are realized by the CPU 42 executing the firmware. The firmware stored in the EEPROM 43 can be updated with new firmware stored in the SD card 5. Functions realized by the computer using the firmware of the control unit 41 include a standby screen display function, a radar scope display function, a GPS alarm function, a radar wave alarm function, a wireless alarm function, and the like.

The standby screen display function is a function that displays the latitude, longitude, and altitude of the host vehicle detected by the GPS receiver 45. The radar scope display function searches for a target within a predetermined range (for example, within a range of about 1 km) from the current position detected by the GPS receiver 45 based on the position information stored in the SD card 5, and automatically displays the target object. This is a function to display the relative positional relationship between the vehicle position and the target object position on the display unit 48.

The control unit 41 executes processes for realizing functions such as a GPS alarm function, a radar wave alarm function, and a radio alarm function, depending on an event that occurs while the standby screen display function or the radar scope display function is being executed.

The GPS alarm function uses the position of the target object (latitude and longitude) stored in the SD card 5 and the current position (latitude and longitude) detected by the GPS receiver 45 while the standby screen display function or radar scope display function is being executed. When the distance obtained is a predetermined proximity warning distance, the data of the photograph or schematic diagram stored in the SD card 5 is read out and displayed on the display unit 48, and the data stored in the SD card 5 is This is a function to perform approach notification by reading out audio data and outputting an approach warning sound from the speaker 51.

These targets include fixed speed measuring devices (including speed measuring devices that emit radar waves (microwaves) such as radar and speed measuring devices that do not emit radar waves such as loop coils), speed limit switching Points, Enforcement areas, Inspection areas, Parking monitoring areas, N system, Traffic monitoring systems, Intersection monitoring points, Traffic light prevention systems, Police stations, Accident-prone areas, Target-on-vehicle areas, Sharp/continuous curves (expressways), Divergence/merging point (expressway), advance ETC lane guidance (expressway), service area (expressway), parking area (expressway), parking area (expressway), highway oasis (expressway), smart interchange (expressway) road), PA/SA gas stations (expressways), tunnels (expressways), highway radio reception areas (expressways), prefectural border announcements, roadside stations, viewpoint parking, etc. The latitude and longitude information shown, the information showing the type of target object, the data of the schematic diagram or photograph displayed on the display unit 48, and the audio data of the sound output from the speaker 51 are associated and stored in the SD card 5. It is managed by a goal related table 251 (see FIG. 6).

For example, while the standby screen display function or the radar scope function is being executed, the distance between the target loop coil and your vehicle becomes 2km, 1km, or 500m, which is the approach warning distance stored in the SD card 5. In this case, the data of the schematic diagram or photograph of the target loop coil is read out from the SD card 5 and displayed on the display section 48, and the audio data stored in the SD card 5 is read out and an alarm sound is output from the speaker 51. Proximity notification that outputs .

The radar wave warning function is activated when the microwave receiver 46 detects a signal corresponding to microwaves in a frequency band emitted from a speed measuring device (a speed measuring device that emits radar waves such as a mobile radar). This is an alarm function that displays an alarm screen on the 48 and outputs an alarm sound from the speaker 51.

The wireless warning function is a function that, when the wireless receiver 47 receives a wireless signal emitted by an emergency vehicle, issues an alert so as not to interfere with the vehicle's movement. Radio alarm functions include enforcement radio, car location radio, digital radio, special small radio, police radio, police telephone, police activity radio, towing radio, helicopter radio, fire helicopter radio, fire radio, emergency radio, and highway radio. , scans the frequencies of security radios, etc., and when a radio signal is received at the scanned frequency, a schematic diagram indicating that a radio signal corresponding to the frequency has been received stored in the SD card 5 for each radio type is displayed on the alarm screen. At the same time, the audio data stored in the SD card 5 for each wireless type is read out, and the speaker 51 outputs an alarm sound indicating the wireless type.

Details of the information stored in the SD card 5 will be explained with reference to FIGS. 3 and 4. As shown in FIG. 3, the SD card 5 includes (1) user ID, (2) type information, (3) goal-related information, (4) registration-related information, (5) OBD information, (6) other information, (7) history information, (8) setting information, and (9) usage start time information are stored. The in-vehicle device 4 executes a GPS warning function, a radar wave warning function, and a wireless warning function based on the information stored in the SD card 5. Each piece of information will be explained in detail below.

(1) The user ID is identification information for identifying the user who uses the SD card 5. When the user inserts the SD card 5 into the in-vehicle device 4 and uses the in-vehicle device 4 for the first time, the user inputs a user ID (for example, "ichiro", "hanako", etc.) into the in-vehicle device 4. The in-vehicle device 4 stores the input user ID in the SD card 5. This allows the user to use the SD card 5 as his or her own. Note that the user ID may be stored in the SD card 5 by the control system 2 while the SD card 5 is inserted into the card reader 29 (see FIG. 5) of the control system 2.

(2) Type information is identification information for identifying the type of in-vehicle device 4 in which the SD card 5 is used. The type information includes the model number of the in-vehicle device 4 (for example, “XXX-1”, etc.) and the version of the firmware that drives the in-vehicle device 4 (for example, “Ver. 1”, etc.). Therefore, even if the model numbers of the in-vehicle devices 4 are the same, different type information is assigned if the firmware that drives the in-vehicle devices 4 is different. For example, "XXX-1 (Ver. 1)" is stored in the SD card 5 as the type information. This type information indicates the type of information such as target related information that can be used in the on-vehicle device 4.

There are two methods for storing type information in the SD card 5: The first method is for the manufacturer to store the type information when the SD card 5 is shipped. When the SD card 5 is enclosed in the vehicle-mounted device 4 in advance, type information corresponding to the enclosed vehicle-mounted device 4 is stored in advance in the SD card 5 by the manufacturer. The second method is a method in which the in-vehicle device 4 stores the type information in the SD card 5. When purchasing and using a general-purpose SD card, the in-vehicle device 4 stores type information in the SD card 5 when the SD card 5 is inserted into the in-vehicle device 4 for the first time. Furthermore, when the firmware that drives the on-vehicle device 4 is updated, the type information is also updated. In this case, the in-vehicle device 4 overwrites and updates the type information stored in the inserted SD card 5 with new type information. The type information is defined within the firmware that drives the in-vehicle device 4. Therefore, if the model number of the in-vehicle device 4 and the version of the firmware that drives the in-vehicle device 4 are different, the type information stored in the SD card 5 is also different.

The firmware of the in-vehicle device 4 is stored in the server 3 and updated as necessary. The control system 2 downloads firmware from the server 3 and stores it in the SD card 5. The in-vehicle device 4 reads the firmware stored in the SD card 5 and stores it in the EEPROM 43. The control unit 41 (see FIG. 3) of the in-vehicle device 4 is driven based on firmware stored in the EEPROM 43. If the type information stored in the SD card 5 differs from the type information defined in the firmware, the in-vehicle device 4 replaces the type information stored in the SD card 5 with the type information defined in the firmware. overwrite and update.

Although the details will be described later, the various information that the in-vehicle device 4 acquires from the server 3 via the SD card 5 differs depending on the type of information of the in-vehicle device 4. This is because different types of firmware can process different types of information. The server 3 provides firmware to the in-vehicle device 4 as needed, manages various information that can be processed by each firmware for each type of information, and provides the information to the in-vehicle device 4 via the control system 2. The control system 2 determines various types of information that can be processed when the in-vehicle device 4 in which the SD card 5 is used is driven based on firmware, based on the type information stored in the SD card 5, and displays appropriate various types of information. is stored in the SD card 5. For this reason, the in-vehicle device 4 stores its own model number and type information corresponding to the firmware in the SD card 5, thereby ensuring that various types of information that can be processed are stored in the SD card 5.

As described above, the type information is stored in the SD card 5 in advance or automatically stored in the SD card 5 by the in-vehicle device 4. Therefore, the user does not need to check the type information corresponding to the in-vehicle device 4 and manually store the type information in the SD card 5.

(3) Target-related information is information related to a target to be notified to the driver. The target-related information includes GPS information, image information, and enforcement information. The GPS information is information in which information indicating the type of target object is associated with latitude and longitude indicating the position of the target object. The image information is information in which information indicating the type of the target object is associated with a schematic diagram or a photograph indicating the target object. Enforcement information is information in which the content of public enforcement announced by each prefectural police station is associated with the location, date and time of the public enforcement.

The in-vehicle device 4 refers to the position information of the own vehicle detected by the GPS receiver 45 and the GPS information stored in the SD card 5 to determine the distance between the current position of the vehicle and the target object. When the calculated distance reaches a predetermined approach warning distance, the on-vehicle device 4 refers to the image information corresponding to the type information of the target object associated with the position of the target object, and responds to the approaching target object. Identify schematic diagrams and photographs. The in-vehicle device 4 displays the identified schematic diagram or photograph on the display unit 48 (see FIG. 2) to notify the driver that the vehicle has approached the target object. Furthermore, the in-vehicle device 4 refers to the enforcement information stored in the SD card 5 to determine whether the vehicle has entered a place where public enforcement is being conducted. The in-vehicle device 4 displays the details of the public enforcement on the display unit 48 when the vehicle enters a place where the public enforcement is being conducted. As a result, the on-vehicle device 4 notifies the driver that a public enforcement operation is being conducted near the vehicle.

(4) Registration-related information includes registration information, invalidation information, detection information, and false detection information. The registration information is information in which information indicating the type of target object registered by the user is associated with latitude and longitude indicating the position of the target object. For example, the user inputs into the in-vehicle device 4 via the touch panel 49 a location where mobile Orbis often appears or a location where a new Orbis is installed. The in-vehicle device 4 stores the input information in the SD card 5 as registration information. When the vehicle approaches the position indicated by the registered information, the in-vehicle device 4 displays a screen on the display unit 48 notifying that the vehicle has approached the registered position, and outputs an alarm sound from the speaker 51. Realizes GPS alarm function.

The invalidation information is latitude and longitude information indicating a position where notification by the in-vehicle device 4 is invalidated. For example, the user inputs to the in-vehicle device 4 via the touch panel 49 a point, such as an automatic door, where the in-vehicle device 4 issues an alarm using the radar wave warning function even though no target object is installed. The in-vehicle device 4 stores the input information in the SD card 5 as invalid information. The in-vehicle device 4 performs the GPS alarm function and the GPS alarm function even when the vehicle approaches the position indicated by the invalid information, when another target is installed nearby, or when the microwave receiver 46 detects microwaves. The radar wave warning function does not notify the driver.

The detection information is information in which the type of speed measuring device detected by the in-vehicle device 4 by receiving microwaves, the latitude and longitude indicating the detection position, and the time of detection are associated with each other. For example, when the in-vehicle device 4 detects microwaves of a frequency output from a mobile Orbis, the in-vehicle device 4 associates information indicating the type of the mobile Orbis, latitude and longitude indicating the detection position, and time of detection, and uses the information as detection information. Store it on the SD card 5. When the vehicle approaches the position indicated by the detection information, the in-vehicle device 4 displays a screen on the display unit 48 notifying that the vehicle is approaching a position where the target object was detected in the past, and sounds an alarm. By outputting from the speaker 51, the GPS alarm function is realized.

The false detection information is information indicating the latitude and longitude of a corresponding location, which is stored when a target object is not actually set although the in-vehicle device 4 detects a microwave. In the false detection information, the latitude and longitude indicating the position where the in-vehicle device 4 made the false alarm, and the time when the false alarm was made are associated with each other. For example, even if the in-vehicle device 4 detects microwaves and issues a notification, if the user determines that the target object is not actually installed, the user may notify the in-vehicle device 4 via the touch panel 49. Enter the fact that it is a false positive. The in-vehicle device 4 stores the input information in the SD card 5 as false detection information. When the vehicle approaches the position indicated by the false detection information, the on-vehicle device 4 does not notify the driver using the GPS warning function and the radar wave warning function even if a target object is installed nearby.

Note that the registration information, invalidation information, detection information, and false detection information may be input by the user via the control system 2. The control system 2 may store the input registration information, invalidation information, detection information, and false detection information in the SD card 5 inserted into the card reader 29 (see FIG. 5).

(5) OBD (On-board diagnostics) information includes vehicle status information, more specifically, engine control information. The OBD information is acquired by the in-vehicle device 4 at predetermined intervals when a dedicated connector provided in the vehicle and the OBD connector 53 (see FIG. 2) are connected. The in-vehicle device 4 associates the acquired OBD information with the acquisition time and stores it in the SD card 5. Based on the acquired OBD information, the on-vehicle device 4 determines engine speed, engine load factor, throttle opening, fuel flow rate, cumulative fuel consumption, instantaneous fuel consumption, average fuel consumption, average road fuel consumption, average highway fuel consumption, lifetime fuel consumption, Lifetime fuel consumption, water temperature, speed, number of revolutions, etc. can be determined. The in-vehicle device 4 can also display various information specified based on the OBD information on the display section 48 while displaying the standby screen on the display section 48 .

(6) Other information includes standby image/audio information, store advertisement image information, and sales advertisement image information. Other information is stored in the SD card 5 by the control system 2.

The standby image/audio information is information about the image displayed on the display unit 48 by the standby screen display function and the sound output from the speaker 51. Note that a plurality of standby image/audio information may be stored in the SD card 5. The user may be able to select the image and audio to be actually used from among the plurality of standby image/audio information via the touch panel 49.

Store advertisement image information is information in which the latitude and longitude indicating the location of a predetermined store are associated with an image for advertising the predetermined store. When the vehicle approaches a predetermined store, the in-vehicle device 4 displays an image for advertising the predetermined store on the display unit 48. Thereby, the store can be advertised to drivers of vehicles passing near the store. Note that the store advertisement image information is not limited to image information for advertising the store. For example, it may be an image for advertising a tourist attraction or an event being held at an event venue.

The sales advertisement image information is image information for introducing the new in-vehicle device 4 to the driver. The in-vehicle device 4 displays a sales advertisement image on the display unit 48 when the usage period of the in-vehicle device 4 has exceeded a predetermined period. The period of use is calculated as described in (9) below. Thereby, the in-vehicle device 4 can prompt the driver to purchase a new in-vehicle device 4. Note that the sales advertisement image is not limited to an image for introducing the new in-vehicle device 4 to the driver. For example, it may be an image that introduces the accessories of the in-vehicle device 4 to the driver. Further, it may be an image for explaining convenient usage of the in-vehicle device 4.

(7) History information is information in which the latitude and longitude indicating the driving position of the vehicle are associated with the driving time. The in-vehicle device 4 associates the travel time with the latitude and longitude indicating the position of the vehicle detected by the GPS receiver 45, and stores the travel time in the SD card 5 at a predetermined period. FIG. 4 shows history information 53 stored in the SD card 5. As shown in FIG. 4, the latitude and longitude indicating the position of the vehicle are stored in chronological order in association with travel times. The in-vehicle device 4 acquires travel time, latitude, and longitude at one-second intervals, and stores them in the SD card 5 as history information 53. Note that the history information 53 stored in the SD card 5 is read out by the control system 2 through a process described later. Based on the read history information 53, the control system 2 can execute a so-called driving simulation that displays the movement of the vehicle in chronological order on a map (see FIG. 22). Details will be described later.

(8) Setting information is information for specifying the driving conditions of the in-vehicle device 4. The setting information includes a plurality of setting items. For example, setting items related to alarm settings include display switching distance (standby screen fixed, 500m, 1000m, radar screen fixed), radar alarm sound (electronic sound, voice, quiet voice, melody 1 to 3, melody rotation), reception sensitivity. Mode (city, extra, super extra, AAC/ASS, AAC/SE), radio alarm (voice alarm, demodulation, OFF), road selection (general road, high speed, all, auto), positioning announcement (ON/OFF) , Orbis location guide (ON/OFF), display format (nose up, heading up), etc. Setting items included in the setting information are changed on the in-vehicle device 4 via the touch panel 49. The in-vehicle device 4 stores the contents of the changed setting items in the SD card 5 as setting information.

Note that in the above description, the setting information can also be input by the user via the control system 2. The control system 2 stores the input setting information in the SD card 5 inserted into the card reader 29 (see FIG. 5) (see FIG. 17, described later).

(9) Usage start time information is information indicating the start time of use of the in-vehicle device 4. The use start time information is stored by the in-vehicle device 4 when the SD card 5 is used by the in-vehicle device 4 for the first time. When the SD card 5 is used for the first time, the in-vehicle device 4 stores the date and time of use in the SD card 5 as usage start time information. The in-vehicle device 4 can determine whether the SD card 5 is used for the first time in the in-vehicle device 4 by determining whether or not use start time information is stored in the inserted SD card 5. The use start time information is used when calculating the usage period of the on-vehicle device 4 when the control system 2 and the on-vehicle device 4 determine whether or not to display a sales advertisement image.

The electrical configuration of the control system 2 will be described with reference to FIG. 5. The control system 2 is provided with a control section 21 that performs main control. The control unit 21 includes a CPU 22, an EEPROM 23, a RAM 24, and the like. The control unit 21 includes a hard disk drive (HDD) 25 storing information stored in the SD card 5 and programs executed by the CPU 22, a communication device 26 for communicating with the server 3 via the network 6, and a color liquid crystal display. A display section 27 consisting of a keyboard and a mouse, an input section 28 consisting of a keyboard and a mouse, and a card reader 29 into which the SD card 5 is inserted are connected.

Information stored in the HDD 25 will be explained. The HDD 25 stores a goal-related table 251 (see FIG. 6), a user ID-related table 252 (see FIG. 7), and an other table 253 (see FIG. 8). Each piece of information will be explained in detail below.

The goal related table 251 will be explained with reference to FIG. In the goal-related table 251, goal-related information acquired by the control system 2 from the server 3 via the network 6 is stored for each type of information. Each goal-related information is associated with an update date and time indicating the date and time when the goal-related information was updated in the server 3.

For example, in FIG. 6, the GPS information corresponding to the type information "XXX-1 (Ver. 1)" is "Ver. 1-1" (updated date and time: 2011/01/05), "Ver. 1-2" (updated Date and time: 2011/03/15) and “Ver.1-3” (updated date and time: 2011/05/15) are stored. Therefore, three pieces of GPS information corresponding to the type information "XXX-1 (Ver. 1)" have been created in the past on the server 3 and made public. On the other hand, the enforcement information corresponding to the type information "XXX-1 (Ver.1)" is "Ver.1-1" (updated date and time: 2011/01/01) and "Ver.1-2" (updated date and time: 2011 /03/01) "Ver.1-3" (updated date and time: 2011/05/01) and "Ver.1-4" (updated date and time: 2011/07/01) are stored. This means that four pieces of enforcement information corresponding to the type information "XXX-1 (Ver. 1)" have been created in the past on the server 3 and made public. Public enforcement information tends to be frequently released by each prefectural police station, so it is updated more frequently than other information. Further, in FIG. 6, goal-related information corresponding to two types of information ("XXX-1 (Ver. 1)" and "XXX-1 (Ver. 2)") is stored.

The user ID correspondence table 252 will be explained with reference to FIG. 7. The user ID correspondence table 252 includes information read out from the SD card 5 by the control system 2 (type information, registration related information (registration information, invalidation information, detection information, false detection information), OBD information, history information, setting information). are stored for each user ID. For example, in FIG. 7, information read from the SD card 5 whose user ID is "ichiro" and information read from the SD card 5 whose user ID is "hanako" correspond to the respective user IDs. It is attached and memorized.

The other table 253 will be explained with reference to FIG. 8. In the other table 253, other information (standby image/audio information, store advertisement image information, and sales advertisement image information) acquired by the control system 2 from the server 3 via the network 6 is stored for each type of information. . Each piece of other information is associated with an update date and time indicating the date and time when the other information was updated in the server 3.

The first control main process executed in the control unit 21 of the control system 2 will be described with reference to FIGS. 9 to 16. In the first control main process, a process is executed to store target-related information, registration-related information, other information, and setting information in the SD card 5 inserted into the card reader 29 (see FIG. 5) as necessary. The control first main process starts when the control unit 21 executes the program stored in the HDD 25.

When the first control main process is started, the control unit 21 first determines whether the SD card 5 is inserted into the card reader 29 (see FIG. 5) (S11). If the SD card 5 is not inserted into the card reader 29 (S11: NO), the process returns to S11. If the SD card 5 is inserted into the card reader 29 (S11: YES), the control unit 21 determines whether type information is stored in the SD card 5 (S13). If the type information is not stored in the SD card 5 (S13: NO), the goal-related information corresponding to the type information cannot be specified, so the process returns to S11.

If the type information is stored in the SD card 5 (S13: YES), the control unit 21 determines whether history information is stored in the SD card 5 (S15). If history information is not stored in the SD card 5 (S15: NO), there is a possibility that the inserted SD card 5 is not actually used in the in-vehicle device 4. This is because if the SD card 5 is used even once in the in-vehicle device 4, history information is stored in the SD card 5. Therefore, if history information is not stored in the SD card 5, no further processing is performed and the process returns to S11 in order to prevent goal-related information etc. from being stored in the SD card 5 that is not actually used. .

As described above, the control system 2 prevents goal-related information and the like from being stored in the SD card 5 that is not actually used by the in-vehicle device 4. This allows the control system 2 to improve the security of target-related information and the like. For example, the control system 2 can provide goal-related information with high added value, such as paid information, only to the SD card 5 that is actually used by the in-vehicle device 4. This prevents target-related information from being leaked and misused.

In addition, the control system 2 determines whether the SD card 5 is actually used in the in-vehicle device 4 based on whether history information is stored in the SD card 5. This makes it possible to easily confirm that the SD card 5 is being used by the in-vehicle device 4. Furthermore, the history information can be used not only as the driving history of the vehicle but also to determine whether or not the SD card 5 is actually used in the in-vehicle device 4. It is efficient because it eliminates the need to add additional information to prove that it is used in

Note that in the present invention, for example, in the case where paid goal-related information is stored only in a specific SD card 5, it may be determined whether or not the goal-related information is stored in the SD card 5 based on separate certification information. For example, if a well-known encryption key is stored in the SD card 5 as proof information, it may be determined that storage of goal-related information in the SD card 5 is permitted.

In S15, if it is determined that the history information is stored in the SD card 5 (S15: YES), the control unit 21 performs a process of reading out the history information stored in the SD card 5 (history read process (see FIG. 11). )) is executed (S17). The history reading process will be explained with reference to FIG. 11. The control unit 21 reads the user ID from the SD card 5 (S61). Next, the control unit 21 reads history information from the SD card 5 (S63). The control unit 21 associates the history information with the user ID and stores it in the user ID correspondence table 252 (see FIG. 7) of the HDD 25 (S65). After storing the history information in the user ID correspondence table 252, the control unit 21 deletes the history information from the SD card 5 (S67). The history reading process ends and the process returns to the control first main process (FIG. 9).

The control system 2 reads the history information from the SD card 5 and stores it in the HDD 25, thereby displaying the history information on the display section 27 (see FIG. 5), or inputting the history information via the input section 28 (see FIG. 5). You will be able to edit. Since the display unit 48 and touch panel 49 (see FIG. 2) provided on the in-vehicle device 4 are smaller than the display unit 27 and input unit 28 of the control system 2, the user can use the in-vehicle device 4 to browse history information. or editing comfortably. On the other hand, by storing the history information in the HDD 25, the control system 2 can view the history information via the display unit 27, which has better visibility than the in-vehicle device 4, and uses the input unit 28, which has excellent operability. Since the history information can be edited through the user interface, the user can comfortably view and edit the history information.

Further, the history information stored in the SD card 5 is deleted after being read by the control system 2. Thereby, when the SD card 5 is repeatedly used in the vehicle-mounted device 4, it is possible to prevent history information from being accumulated and the storage capacity of the SD card 5 becoming insufficient.

After the history reading process (S17, see FIG. 11) ends, as shown in FIG. 9, the control unit 21 reads out the type information stored in the SD card 5 (S19). The control unit 21 starts an application for storing information in the SD card 5 (S21). Subsequently, the control unit 21 displays a selection screen for information to be stored in the SD card 5 on the display unit 27.

The selection screen 271 displayed on the display unit 27 will be described with reference to FIG. 16. The selection screen 271 includes an area 272 for displaying type information and user ID stored in the SD card 5, an area 273 for displaying a sales advertisement image, and a check box area 274 for selecting information to be stored in the SD card 5. It is provided. The checkbox area 274 includes target-related information (GPS information, image information, enforcement information), registration-related information (registration/invalidation information, detection/false detection information), setting information, and other information (standby screen/audio information, store Check boxes are provided for selecting whether to share advertisement information, sales advertisement information), and whether or not to share the information. The user specifies the information he/she desires to store in the SD card 5 by checking the checkbox, and selects the OK button. As a result, the specified information is stored in the SD card 5 through a process described later. Note that when specifying enforcement information among the target-related information, the user also selects one or more specific areas from a list box for specifying areas. This specifies the area where public enforcement information will be implemented. When specifying sharing, the user also selects one or more specific users from a list box for specifying users. Thereby, information corresponding to other users can be stored in the own SD card 5.

As shown in FIG. 9, the control unit 21 acquires the usage start time information stored in the SD card 5 (S23). The control unit 21 calculates the usage period of the in-vehicle device 4 in which the SD card 5 is used based on the acquired usage start time information. The control unit 21 determines whether the calculated period of use has exceeded a predetermined period (for example, three months) (S25). If the calculated period of use is less than the predetermined period (S25: NO), the period of use of the in-vehicle device 4 is still short, so the process proceeds to S29.

On the other hand, if the calculated period of use has exceeded the predetermined period (S25: YES), it means that the in-vehicle device 4 has been used for a long time. The control unit 21 acquires sales advertisement image information corresponding to the type information read in S19 and having the latest update date and time from the server 3 via the network 6. Note that the server 3 creates sales advertisement information advertising a new model of the in-vehicle device 4 and updates the sales advertisement information at a cycle shorter than a predetermined period. The control unit 21 stores the acquired sales advertisement image information in the other table 253 (see FIG. 8) of the HDD 25. The control unit 21 selects sales advertisement image data from the sales advertisement image information acquired from the server 3. The control unit 21 displays the image data of the selected sales advertisement in the area 273 of the selection screen 271 (see FIG. 16) displayed on the display unit 27 (S27). The image of the sales advertisement includes information about a new product such as a new in-vehicle device 4 that is different from the in-vehicle device 4 of the specified type information, and information about the in-vehicle device 4 such as an optional product of the in-vehicle device 4 specified by the type information. Contains images to promote related products and services. The sales advertisement image also includes a list of functions of the in-vehicle device 4 to be advertised. As a result, the control system 2 can notify the user of the time to replace the in-vehicle device 4 and urge the user to purchase a new in-vehicle device 4. The process advances to S29.

Assume that the user checks the checkbox and selects the OK button via the selection screen 271 (see FIG. 16) displayed on the display unit 27. The control unit 21 identifies the item of information specified by the user (S29). The control unit 21 executes the process of storing information on the identified items in the SD card 5 as follows.

As shown in FIG. 10, if the user has checked any item among the goal-related information and other information and selected the OK button (S31: YES), A process (first storage process, see FIG. 12) for storing information on the specified item in the SD card 5 is executed (S33). After the first storage process is completed, the process proceeds to S35. On the other hand, if the user has not specified any item of goal-related information or other information (S31: NO), the process proceeds to S35.

The first storage process will be explained with reference to FIG. 12. In the following description, it is assumed that image information among the target-related information is designated by the user as the information to be stored in the SD card 5. However, similar processing is performed even when information other than image information is specified among the goal-related information and other information. The control unit 21 acquires image information corresponding to the type information read in S19 (see FIG. 9) and having the latest update date and time via the network 6 by inquiring the server 3 (S71). . The control unit 21 compares the update date and time of the image information stored in the SD card 5 with the update date and time of the image information acquired in S71. If the update date and time of the image information acquired in S71 is newer than the update date and time of the image information stored in the SD card 5, it means that the image information has been newly updated in the server 3 (S73: YES). In this case, the control unit 21 associates the type information and the update date and time with the image information acquired in S71 and stores it in the target related table 251 (see FIG. 6) of the HDD 25 (S75). The control unit 21 calculates difference information that is information about the difference between the latest image information stored in the HDD 25 and the image information stored in the SD card 5 (S77). The control unit 21 stores the calculated difference information in the temporary area of the SD card 5 (S79). The process advances to S81.

The in-vehicle device 4 reconstructs the image information with the latest update date and time from the image information already stored in the SD card 5 and the difference information stored in the temporary area by the control system 2. The control unit 21 stores the reconstructed image information in the SD card 5 as regular image information. The in-vehicle device 4 becomes able to read and use the image information stored in the SD card 5.

As described above, the control system 2 updates the information stored in the SD card 5 by calculating and storing the difference information in the SD card 5. For example, as described above, when image information is specified as target-related information, the amount of image information is generally large, so the amount of image information stored in the SD card 5 increases. Therefore, if the image information is stored as is in the SD card 5, it may take time to store it. If multiple pieces of information are specified by the user, the amount of information will be even larger, and the time required to store it will be even longer. On the other hand, in the control system 2, since the difference information is stored in the SD card 5, the amount of information stored in the SD card 5 can be suppressed. Therefore, the control system 2 can shorten the time required to store information on the SD card 5.

Furthermore, the control system 2 acquires information corresponding to the same type information from the server 3 and stores it in the SD card 5, thereby ensuring that the in-vehicle device 4 can refer to the information stored in the SD card 5. There is. Here, the type information includes information indicating the model of the in-vehicle device 4 (for example, "XXX-1") and information indicating the firmware version (for example, "Ver. 1"), so the in-vehicle device of the same model Even when the in-vehicle devices 4 are driven based on different firmware, information usable by each in-vehicle device 4 can be reliably acquired from the server 3 and stored in the SD card 5. Therefore, the in-vehicle device 4 can reliably notify the driver by referring to the SD card 5.

Note that when the user specifies enforcement information among the target-related information, the region is also selected on the selection screen 271 (see FIG. 16). When acquiring enforcement information from the server 3 in S71, the control unit 21 specifies and acquires enforcement information for the area designated by the user. The control unit 21 calculates difference information between the enforcement information of the designated area and the enforcement information of the designated area stored in the SD card 5, and stores it in a temporary area of the SD card 5. In this way, the control system 2 can narrow down the enforcement information according to the designated area and store it in the SD card 5. This allows the control system 2 to further suppress the amount of information stored in the SD card 5. Note that the driver only needs to be notified of information regarding public enforcement that will be implemented in the area including the current location of the vehicle or the area through which the vehicle will travel before heading to the destination. Therefore, if the enforcement information for these areas is stored in the SD card 5, the in-vehicle device 4 can reliably notify the driver of the enforcement information necessary for the driver.

On the other hand, if the update date and time of the image information stored in the SD card 5 and the update date and time of the image information acquired in S71 are the same, the image information stored in the SD card 5 is the latest, and the image information is updated in the server 3. Not done (S73: NO). In this case, there is no need to store image information in the SD card 5, so the process proceeds to S81.

In S81, it is determined whether all the items specified by the user through the selection screen 271 (see FIG. 16) have been processed (S81). If there remain unprocessed items (S81: NO), the process returns to S71. On the other hand, if all items of goal-related information and other information specified by the user have been processed (S81: YES), the first storage process ends, and the process starts with the control first main process (see FIG. 10). ).

In S35 of FIG. 10, it is determined whether the user has checked the registration related information item and selected the OK button via the selection screen 271 (see FIG. 16) displayed on the display unit 27 (S35). If the user has not checked any item of the registration-related information (S35: NO), the control unit 21 determines whether the registration-related information and OBD information are stored in the SD card 5 (S39). ). If the registration-related information and OBD information are stored in the SD card 5 (S39: YES), the control unit 21 executes a process of reading the registration-related information and OBD information from the SD card 5 (reading process, see FIG. 13). (S41). After the process ends, the process proceeds to S43. Details of the read processing will be described later. On the other hand, if the registration related information and OBD information are not stored in the SD card 5 (S39: NO), the process proceeds to S43.

On the other hand, if it is determined in S35 that the user has specified any item of the registration related information (S35: YES), the process of storing the information of the specified item in the SD card 5 (second storage process , see FIG. 14) (S37). After the process ends, the process proceeds to S43. Details of the second storage process will be described later.

The read process will be described with reference to FIG. 13. The control unit 21 reads the user ID stored in the SD card 5 (S91). The control unit 21 reads registration related information (registration information, invalidation information, detection information, and false detection information) and OBD information stored in the SD card 5 (S93). Note that since the detection information, false detection information, and OBD information are associated with time, the associated time is also read out. The control unit 21 associates the registration related information and OBD information (including time) with the user ID and stores them in the user ID correspondence table 252 (see FIG. 7) of the HDD 25 (S95). The read process ends and the process returns to the control first main process (see FIG. 10).

By executing the above processing, the control system 2 can effectively utilize the acquired registration related information (registration information, invalidation information, detection information, and false detection information). For example, the control system 2 may arrange an image for specifying the type of the registered target on a map and display it on the display unit 27 based on the acquired registration related information. Since the control system 2 is provided with a display section 27 that is larger than the in-vehicle device 4, the user can clearly recognize the registration-related information displayed on the display section 27.

Furthermore, the control system 2 can effectively utilize OBD information. For example, the control system 2 may display the OBD information on the display unit 27 while changing the OBD information in order based on the time associated with the OBD information. As a result, the OBD information is displayed on the display section 27 that is larger than the display section 48 provided in the in-vehicle device 4, so that the user can clearly see and recognize the OBD information.

The second storage process will be described with reference to FIG. 14. The control unit 21 reads the user ID stored in the SD card 5 (S101). The control unit 21 acquires registration related information corresponding to the user ID read in S101 from among the information stored in the user ID correspondence table 252 (see FIG. 7) (S103). The control unit 21 stores the acquired registration related information in the SD card 5 (S105). The second storage process ends and the process returns to the first control main process (see FIG. 10).

By executing the above process, the user can drive the in-vehicle device 4 using registration related information specific to the user. For example, when a common in-vehicle device 4 is jointly used by a plurality of people, each user preferably owns an SD card 5 storing a user ID for identifying the user. As a result, the SD card 5 stores registration-related information unique to each user, so that the in-vehicle device 4 can be driven based on the registration-related information unique to each user.

In S43 of FIG. 10, it is determined whether the user has checked the setting information and selected the OK button via the selection screen 271 (see FIG. 16) displayed on the display unit 27 (S43). If the user has not specified the setting information (S43: NO), the control unit 21 determines whether the setting information is stored in the SD card 5 (S45). If the setting information is not stored in the SD card 5 (S45: NO), the process proceeds to S53. If the setting information is stored in the SD card 5 (S45: YES), the control unit 21 executes a process of reading out the setting information (reading process, see FIG. 13) (S47). As shown in FIG. 13, the control unit 21 reads out the user ID stored in the SD card 5 (S91). The control unit 21 reads out the setting information stored in the SD card 5 (S93). The control unit 21 associates the setting information with the user ID and stores it in the user ID correspondence table 252 (see FIG. 7) of the HDD 25 (S95). The read process ends and the process returns to the control first main process (see FIG. 10). As shown in FIG. 10, when the read process is completed, the control unit 21 associates the user ID with the setting details and transmits the association to the server 3 via the network 6 (S49). The server 3 associates the received user ID and setting information and stores them in a database.

On the other hand, if the user has specified setting information (S43: YES), a process for storing the setting information in the SD card 5 (third storage process, see FIG. 15) is executed (S51).

The third storage process will be explained with reference to FIG. 15. The control unit 21 reads the user ID stored in the SD card 5 (S111). Next, the setting information corresponding to the user ID read in S111 is selected from among the setting information stored in the user ID correspondence table 252 (see FIG. 7) of the HDD 25 (S113). Note that the user ID correspondence table 252 stores setting information previously read from the SD card 5 or setting information directly input by the user into the control system 2 via the input unit 28 (control Second main processing (see FIG. 17, described later)).

The control unit 21 determines whether the setting information stored in the user ID correspondence table 252 has been successfully read (S115). If the reading of the setting information is successful (S115: YES), the read setting information is stored in the SD card 5 (S119). By reading and using the setting information stored in the SD card 5, the in-vehicle device 4 can be driven based on the setting information. The third storage process ends, and the process returns to the control first main process (see FIG. 10).

As described above, in the control system 2, the setting information is stored in the user ID correspondence table 252 in association with the user ID, so the setting information corresponding to the user ID stored in the SD card 5 is stored in the SD card 5. By storing the information, the in-vehicle device 4 can be operated under the setting conditions for each user. For example, when a common in-vehicle device 4 is jointly used by a plurality of people, each user preferably owns an SD card 5 storing a user ID for identifying the user. This allows the user to always operate the in-vehicle device 4 with the desired settings without having to input operation settings every time the in-vehicle device 4 is used.

On the other hand, if the reading of the setting information stored in the user ID correspondence table 252 fails (S115: NO), the control unit 21 notifies the server 3 of the user ID to read the setting information corresponding to the user ID. It is acquired from the server 3 (S117). The control system 2 has a function to transfer the input setting information to the server 3 when the setting information is read from the SD card 5 or when the user directly inputs the setting information to the control system 2. (See FIGS. 10 and 17, described later). For this reason, the server 3 stores setting information in association with the user ID. In response to an inquiry from the control system 2, the server 3 can transmit setting information corresponding to the notified user ID to the control system 2. The control system 2 acquires the setting information from the server 3 and stores it in the SD card 5 (S119). The third storage process ends, and the process returns to the control first main process (see FIG. 10).

As described above, even if the control system 2 is unable to acquire the setting information from the user ID correspondence table 252 due to a failure of the HDD 25 or the like, the control system 2 can ensure that the setting information is stored in the SD card 5 by inquiring the server 3. can do. This saves the user the trouble of resetting the in-vehicle device 4 when the HDD 25 fails.

In S53 of FIG. 10, it is determined whether the user has designated sharing via the selection screen 271 (see FIG. 16) displayed on the display unit 27 (S53). If the user determines that sharing has not been specified (S53: NO), the process returns to S11 (see FIG. 9). On the other hand, if it is determined that the user has specified sharing (S53: YES), the setting information corresponding to the selected user is stored in the SD card 5 at the same time as the user specifies sharing on the selection screen 271. Then, the control unit 21 executes the third storage process (FIG. 15) (S55).

As shown in FIG. 15, in the third storage process, the control unit 21 acquires the user ID of the selected user at the same time as the user specifies sharing (S111). The control unit 21 acquires setting information corresponding to the acquired user ID from the user ID correspondence table 252 of the HDD 25 (S113). If the acquisition of the setting information is successful (S115: YES), the control unit 21 stores the acquired setting information in the SD card 5 (S119). The third storage process ends, and the process returns to the control first main process (see FIG. 10). As shown in FIG. 10, after the third storage process (S55) ends, the process returns to S11 (see FIG. 9).

As described above, the control system 2 can store, in the SD card 5, setting information corresponding to a user ID different from the user ID stored in the SD card 5. This allows the user to drive the in-vehicle device 4 using the setting information used by other users as is.

In the above description, an example is given in which the setting information used in the in-vehicle device 4 of a specific user is shared by other users by storing the setting information corresponding to the specified user ID in the SD card 5. However, the information shared is not limited to configuration information. In the control system 2, other information stored in the user ID correspondence table 252, such as registration related information, may be shared by other users.

As explained above, when the control system 2 executes the first control process, the user can transfer target-related information that can be used in the in-vehicle device 4 to the SD card without performing any specifying operation on the control system 2. 5 can be stored. The in-vehicle device 4 can reliably perform notification regarding the target object by referring to the SD card 5 in which target-related information is stored. Since the user does not need to know in advance information for specifying information that can be used in the in-vehicle device 4, for example, type information of the in-vehicle device 4, the user can update the goal-related information stored in the SD card 5. It can be done quickly and easily.

The second control main process executed in the control unit 21 of the control system 2 will be described with reference to FIGS. 17 to 21. In the second control main process, a process is executed in which setting information of the in-vehicle device 4 input by the user via the input unit 28 is acquired and stored in the user ID correspondence table 252 (see FIG. 7) of the HDD 25. Note that the setting information stored in the user ID correspondence table 252 is stored in the SD card 5 inserted into the card reader 29 (see FIG. 5) of the control system 2 by the above-described first control main process. When the user inputs an instruction to start inputting setting information, the second control main process is started by the control unit 21 executing the program stored in the HDD 25.

When the second control main process is started, the control unit 21 first displays a screen for inputting the user ID on the display unit 27 (see FIG. 5), and prompts the user to input the user ID. When the user inputs a user ID via the input unit 28 (see FIG. 5), the control unit 21 acquires the input user ID (S121). Subsequently, the control unit 21 displays on the display unit 27 a screen on which the input method of setting information can be selected. There are three methods for inputting setting information: When inputting setting information, the user selects one of the methods and performs the input operation.
(1) A method in which the user specifies the setting information item desired by the user and changes the setting contents by hierarchically guiding the user's operations.
(2) A method of identifying the most suitable setting information item in response to a user's question based on a FAQ format, and changing the setting contents.
(3) A method in which the settings information items desired by the user are displayed in order and the settings can be changed, etc. (conventional method)

FIG. 18 shows setting information 61 of the in-vehicle device 4. In this way, the setting information 61 includes a large number of items, and each item is hierarchically organized. Here, in the conventional method of changing the settings of a desired item via the in-vehicle device 4, the touch panel 49 is operated to scroll through each item until the desired item is displayed on the display section 48. do. After the desired item is displayed on the display section 48, the setting contents of the item displayed on the display section 48 are changed. Therefore, in the conventional method, not only does it take time to display the desired item on the display section 48, but also the desired item is easily overlooked. Furthermore, since there are a large number of settings information items, the user may not know which item to change to drive the in-vehicle device 4 in a desired manner.

On the other hand, as shown in FIG. 17, when it is detected that the user has performed an input operation to select the method (1) (S123: YES), the control unit 21 selects the items included in the setting information 61. By sequentially displaying the settings in a hierarchical manner (S125), setting items can be changed efficiently in a short time. The HDD 25 of the control system 2 stores setting information 61 of the in-vehicle device 4 for each type of information. Note that the control unit 21 preferably obtains the setting information 61 corresponding to each of the in-vehicle devices 4 having different type information from the server 3 in advance, and stores it in the HDD 25 in association with the type information. When the control unit 21 starts the second control main process, the control unit 21 reads the type information stored in the SD card 5 inserted into the card reader 29 and requests the corresponding setting information 61 from the server 3. It is preferable to acquire the setting information 61 from 3 and store it in the HDD 25. Based on the setting information 61 stored in the HDD 25 as described above, the control unit 21 displays items included in the setting information as follows. This will be explained below with reference to screen transition 65 in FIG. As shown in FIG. 19, first, the control unit 21 displays a “setting” button 62 on the display unit 27. If it is detected that the user selects the "Settings" button 62, the control unit 21 displays the "Radar", "GPS", and "Wireless" buttons, which correspond to items in the lower hierarchy of "Settings", on the display screen. Displayed on 27. Subsequently, when the selection of the "Radar" button 63 by the user is detected, the control unit 21 selects each of "I Cancel", "I Cancel Sound", and "Opposite Cancel", which correspond to items in the lower hierarchy of "Radar". A button is displayed on the display section 27.

"I Cancel" is a function that automatically registers GPS location information when passing through a place that causes a false alarm, such as an automatic door, and cancels the radar alarm if radio waves are received from the second time onwards. "I cancel sound" is a function that outputs a sound saying "Cancelling" during I cancel. "Opposite Cancellation" is a function that cancels radar wave reception warnings in the opposite lane of the new H system and radar-type Orbis Point registered in GPS information. Subsequently, when the user's selection of the "opposite cancel" button 64 is detected, the control unit 21 displays buttons "ON" and "OFF" corresponding to the settings for "opposite cancel". By detecting a user's selection of one of the "ON" and "OFF" buttons, the opposite cancellation function is turned ON/OFF.

As shown in FIG. 17, the control unit 21 acquires the setting information item and setting content selected by the user (S127). The control unit 21 stores the acquired setting information items and setting contents in association with the user ID acquired in S121 as setting information in the user ID correspondence table 252 (see FIG. 7) of the HDD 25 (S131). The control unit 21 associates the user ID with the setting information items and setting contents, and transmits it to the server 3 via the network 6 (S161). The server 3 associates the received user ID, item, and setting details and stores them in a database. The second control main process ends.

By performing the above-described processing, the user can perform input operations hierarchically according to the guidance, so that the user can easily specify the setting information items necessary to drive the in-vehicle device 4 in a desired manner. , you can change the settings. Therefore, the user can quickly and efficiently change the driving method of the in-vehicle device 4.

On the other hand, if it is detected that the user has performed an input operation to select the method (2) (S123: NO, S133: YES), the control unit 21 selects the setting information item in response to the user's inquiry. Identify and accept changes to settings. As a result, even if the user does not know how to change the setting items to drive the in-vehicle device 4 in the desired driving method, the user can change the setting contents of the optimal items. can. In the HDD 25 of the control system 2, character string information that prompts the user to change the setting information is stored for each setting information in association with a related keyword. The control unit 21 prompts the user to change the setting information by selecting a character string corresponding to the keyword input by the user and displaying it on the display unit 27. If there are multiple character strings corresponding to the keyword input by the user, all of the multiple character strings are displayed on the display section 27. When the user inputs a plurality of keywords, a character string associated with all the keywords is selected and displayed on the display section 27. Note that the control unit 21 preferably obtains in advance from the server 3 a combination of character strings and keywords corresponding to each of the in-vehicle devices 4 having different type information, and stores them in the HDD 25 in association with the type information. When the control unit 21 starts the second control main process, the control unit 21 reads the type information stored in the SD card 5 inserted into the card reader 29 and requests the server 3 for the corresponding combination of character strings and keywords. It is preferable to acquire character strings and keywords from the server 3 and store them in the HDD 25. The control unit 21 performs display control as follows based on the character strings and keywords stored in the HDD 25 as described above.

This will be explained below with reference to FIGS. 20 and 21. As shown in FIG. 20, the control unit 21 displays on the display unit 27 an input screen 66 on which a keyword can be input (S135, see FIG. 17). Here, it is assumed that the user inputs the keyword "opposite lane orbis cancel" via the input unit 28 and selects the OK button. The control unit 21 acquires the input keyword (S137, see FIG. 17).

Subsequently, the control unit 21 reads a character string including the input keyword from the HDD 25. As shown in FIG. 21, the control system 2 displays a notification screen 67 on the display unit 27 that notifies the character string "Radar⇒Turn on opposite cancellation." This prompts the user to turn on the setting information item "opposite cancel function" (S139, see FIG. 17). It is assumed that the user understands and selects the OK button. The control unit 21 specifies "opposite cancellation function" as an item of setting information, and specifies "ON" as the setting content (S141). The control unit 21 stores the specified setting information items and setting contents in the user ID correspondence table 252 of the HDD 25 as setting information in association with the user ID acquired in S121 (S145). The control unit 21 associates the user ID with the items and setting contents, and transmits it to the server 3 via the network 6 (S161). The server 3 associates the received user ID, item, and setting details and stores them in a database. The second control main process ends.

As described above, when the user makes an inquiry to the control system 2 using a keyword, the control system 2 can specify the setting information item and setting content desired by the user. Therefore, even if the user does not have detailed knowledge regarding the in-vehicle device 4, the settings of the specified items are stored in the SD card 5, so that the in-vehicle device 4 can be driven in the driving method desired by the user. do.

The display section 27 displays information regarding the optimal setting information item for the content of the inquiry using the keyword, and the user can directly change the corresponding item by selecting the OK button. . Therefore, the user can save the effort of performing input operations many times to change the screen and specify the item to be changed. Therefore, by quickly specifying the desired item, the user can drive the in-vehicle device 4 in a desired driving method.

Note that when the user performs an input operation to select method (2), the control unit 21 may perform the following process instead of S135 to S145 described above. A web system for realizing a FAQ search system is provided on a server on the Internet (for example, it may be the server 3). The user uses the control system 2 to launch a browser and access this FAQ search page. The user inputs keywords and the like into the search page. The server generates setting information in which items and contents of setting information for driving the in-vehicle device 4 are associated with each other in accordance with the search results corresponding to the keywords. Setting information is displayed on the browser so that it can be downloaded. The user selects the setting information, and the control system 2 downloads the setting information. The control unit 21 stores the items and contents of the setting information included in the downloaded setting information in the user ID correspondence table 252 of the HDD 25 in association with the user ID. At the same time, the items and contents of the downloaded setting information may be stored in the SD card 5.

On the other hand, if it is detected that the user has performed an input operation to select the method (3) (S133: NO), the setting information 61 (see FIG. 18) is displayed according to the user's input operation via the input unit 28. Each item is sequentially displayed on the display section 27 (S147). Assume that the user performs an input operation to change the settings of the item being displayed. The control unit 21 acquires the input settings (S149). The control unit 21 stores the acquired setting information items and setting contents in the user ID correspondence table 252 of the HDD 25 as setting information in association with the user ID acquired in S121 (S151). The control unit 21 associates the user ID with the items and setting contents, and transmits it to the server 3 via the network 6 (S161). The server 3 associates the received user ID, item, and setting details and stores them in a database. The second control main process ends.

As described above, the user can input setting information for the in-vehicle device 4 by directly operating the control system 2 . The display unit 48 and touch panel 49 provided in the vehicle-mounted device 4 cannot be made large due to the size restriction of the vehicle-mounted device 4 as a whole. Therefore, the user cannot easily change settings via the in-vehicle device 4. On the other hand, the control system 2 is provided with an input section 28 that has better operability than the in-vehicle device 4, and a display section 27 that has better visibility. Therefore, the user can easily change the settings. Note that the in-vehicle device 4 operates based on the setting information stored in the SD card 5. Therefore, the control system 2 can change the driving conditions of the in-vehicle device 4 by storing the input setting information in the SD card 5. The user can easily drive the in-vehicle device 4 under desired driving conditions.

The driving simulation function provided in the control system 2 will be explained with reference to FIG. 22. Suppose that it is detected that the user has input an instruction to start a driving simulation together with the user ID via the input unit 28 . The control system 2 reads history information corresponding to the input user ID from the user ID correspondence table 252 (see FIG. 7). The control system 2 displays the simulation image 300 shown in FIG. 22 on the display unit 27 based on the read history information, and starts the driving simulation. Note that when the user inputs an instruction to start the driving simulation, the control unit 21 transmits a request signal to the server 3 to determine the area specified by the latitude and longitude indicating the driving position of the vehicle in the historical information. A map image 301 of the surrounding area may be acquired from the server 3 and stored in the HDD 25. The control unit 21 may create a simulation image 300 including the map image 301 stored in the HDD 25 and display it on the display unit 27.

As shown in FIG. 22, the simulation image 300 includes a map image 301 around an area specified by the latitude and longitude indicating the driving position of the vehicle among the historical information. Further, a mark 302 indicating a place where the vehicle has passed is displayed at a point indicated by latitude and longitude. Note that the marks 302 are sequentially displayed on the map image 301 in the order of travel times included in the history information. This allows the user to check the route of the road on which the vehicle has actually traveled in chronological order, allowing the user to more intuitively recognize his or her own driving history. Furthermore, the display unit 27 provided in the control system 2 is larger and has better visibility than the display unit 48 provided in the vehicle-mounted device 4, so the user can comfortably view the driving history.

The control system 2 also reads OBD information corresponding to the input user ID from the user ID correspondence table 252 of the HDD 25. The control system 2 refers to the OBD information detected at the time the vehicle is traveling, out of the read OBD information, and identifies the traveling speed of the vehicle. The identified traveling speed is displayed as a speed display 305, superimposed on the map image 301.

In addition, the control system 2 selects GPS information stored in the target-related table 251 (see FIG. 6) that is updated to a time earlier than the travel time included in the history information and closest to the travel time. Read information. The control system 2 determines whether the distance between the vehicle and the target object has reached the approach warning distance based on the read GPS information and the latitude and longitude included in the history information. When the distance between the vehicle and the target reaches the approach warning distance, image information 304 corresponding to the approaching target is read from the target related table 251 and displayed over the map image 301. As described above, the control system 2 can display, on the map image 301, an image showing the target object that was actually installed on the road at the time when the vehicle was traveling. Furthermore, the control system 2 can display the traveling speed superimposed on the map image 301 together with the image of the target object. These allow the user to experience a highly realistic driving simulation, allowing the user to view the driving history as if they were actually there.

Note that in the above description, the traveling speed is always displayed superimposed on the map image 301, but the traveling speed may be displayed only when the image information 304 corresponding to the target object is displayed superimposed on the map image 301. .

With reference to FIG. 23, the in-vehicle main processing executed by the control unit 41 of the in-vehicle device 4 will be described. In the in-vehicle main process, a drive process is executed based on information stored in the SD card 5. When the vehicle starts traveling, the in-vehicle main processing is started by the control unit 41 executing a program stored in the EEPROM 43.

When the in-vehicle main processing is started, the control unit 41 first determines whether the SD card 5 is inserted into the card reader 52 (see FIG. 2) (S181). If the SD card 5 is not inserted into the card reader 52 (S181: NO), the in-vehicle device 4 cannot be driven, and the process returns to S181. If the SD card 5 is inserted into the card reader 52 (S181: YES), the control unit 41 determines whether type information is stored in the SD card 5 (S183). If the type information is not stored in the SD card 5 (S183: NO), the SD card 5 inserted into the card reader 52 is being used for the first time, and the information necessary to notify the driver is not stored. There is a possibility that it is not. The control unit 41 stores the type information of the in-vehicle device 4 in the SD card (S185). The in-vehicle main processing ends. Note that by inserting the SD card 5 in which type information is stored into the card reader 29 (see FIG. 5) of the control system 2, necessary information is stored in the SD card 5 (control first main processing, FIG. 9). , see Figure 10).

For example, when the general-purpose SD card 5 is used for the first time, the type information of the in-vehicle device 4 is not stored in the SD card 5. In order to store necessary information in the SD card 5 by using the control system 2, the type information of the in-vehicle device 4 needs to be stored in the SD card 5. Here, when the user manually stores the type information of the in-vehicle device 4 in the SD card 5, the user needs to confirm the type of the in-vehicle device 4, which is troublesome. Furthermore, if incorrect type information of the in-vehicle device 4 is stored in the SD card 5, the in-vehicle device 4 will no longer be able to perform notification processing to the driver. On the other hand, if the type information is not stored in the SD card 5, the in-vehicle device 4 can store its own type information in the SD card 5. Thereby, the type information of the in-vehicle device 4 is accurately and reliably stored in the SD card 5. Therefore, the control system 2 can reliably store information that can be used in the in-vehicle device 4 in the SD card 5. By referring to the SD card 5, the in-vehicle device 4 can reliably notify the driver.

Note that if the type information stored in the SD card 5 is different from its own type information, the in-vehicle device 4 does not overwrite and store its own type information on the SD card 5. This can prevent the information stored in the SD card 5 from being rewritten based on new type information.

On the other hand, if the type information is stored in the SD card 5 (S183: YES), the control unit 41 determines whether the setting information is stored in the SD card 5 (S187). If the setting information is stored in the SD card 5 (S187: YES), the control unit 41 reads the setting information stored in the SD card 5 and sets it in the in-vehicle device 4 (S189). This allows the in-vehicle device 4 to be driven based on the setting information stored in the SD card 5. The process advances to S191. On the other hand, if the setting information is not stored in the SD card 5 (S187: NO), the control unit 41 reads default setting information from the EEPROM 43 and sets it in the in-vehicle device 4. The process advances to S191.

The control unit 41 determines whether the user has input an instruction to start notifying the driver via the touch panel 49 (see FIG. 2) (S191). If the user has not input an instruction to start notifying the driver (S191: NO), the process returns to S191. On the other hand, when the user inputs an instruction to start notification (S191: YES), the control unit 41 first acquires the usage start time information stored in the SD card 5. The usage period of the in-vehicle device 4 is calculated from the acquired usage start time information and the current date and time. The control unit 41 determines whether the calculated usage period is longer than or equal to a predetermined period (S193). If the calculated usage period is longer than the predetermined period (S193: YES), the control unit 41 selects the sales advertisement image information with the latest update date and time from among the other information stored in the SD card, and displays the sales advertisement image information. Read image data. The control unit 41 displays the read image data of the sales advertisement on the display unit 48 (S195). The process advances to S197. On the other hand, if the calculated period of use is less than the predetermined period (S193: NO), the process proceeds to S197.

The control unit 41 starts notifying the driver based on the target-related information, registration-related information, and other information stored in the SD card 5 (S197). Specifically, the control unit 41 realizes the above-described standby screen display function, radar scope display function, GPS alarm function, radar wave alarm function, and radio alarm function. At the same time, the control unit 41 starts storing the history information in the SD card 5 (S199). The control unit 41 selects the store advertisement image information with the latest update date and time from among the other information stored in the SD card 5. The control unit 41 determines whether the distance between the predetermined store and the vehicle is less than or equal to a predetermined value based on the location of the predetermined store and the location of the vehicle (S201). If the distance between the predetermined store and the vehicle is equal to or greater than the predetermined value (S201: NO), the process proceeds to S205. On the other hand, when the distance between the predetermined store and the vehicle becomes less than or equal to the predetermined value (S201: YES), the control unit 41 reads store advertisement image data from the selected store advertisement image information. The control unit 41 displays the read image data of the store advertisement on the display unit 48 (S203). The process advances to S205. By performing the above display control, the driver can recognize advertising information regarding facilities, etc. near the vehicle. The in-vehicle device 4 not only provides information regarding the target object but also provides the driver with additional information based on the vehicle position, thereby enabling the driver to obtain various information while driving.

The control unit 41 determines whether or not the driver has input an instruction to end the notification processing regarding the target object via the touch panel 49 (S205). If the driver has not inputted an instruction to end the notification process regarding the target object (S205: NO), the process returns to S199. On the other hand, if the driver inputs an instruction to end the notification process regarding the target object via the touch panel 49 (S205: YES), the in-vehicle main process ends.

Note that the present invention is not limited to the above-described embodiments, and various modifications are possible. When the SD card 5 is inserted into the card reader 29, the control system 2 executes a process of reading history information and registration related information from the SD card 5. For example, the history information and registration related information stored in the SD card 5 may be classified into information that can be read by the control system 2 and information that cannot be read by the control system 2. For example, the SD card 5 may have a folder that stores information that can be read by the control system 2 and a folder that stores information that cannot be read by the control system 2. The control system 2 may read only readable information from the SD card 5 and store it in the HDD 25.

For example, from the viewpoint of protecting user privacy, it is desirable that historical information including the vehicle's travel position and travel time not be read by the control system 2. On the other hand, the registration related information is preferably incorporated into the control system 2 because the latest target information can be obtained by sharing it among multiple people. In this case, it is preferable to store history information in a folder that stores unreadable information, and store registration information and invalidation information in a folder that stores readable information. This allows the control system 2 to take in only the registration-related information. In this way, it is possible to prevent all information stored in the SD card 5 from being taken into the control system 2.

When storing the goal-related information in the SD card 5, the control system 2 stores the goal-related information with the latest update date and time in the goal-related table 251 (see FIG. 6). For example, the control system 2 may store, in the SD card 5, only the target related information of target objects that are within the main movement range of the vehicle in which the in-vehicle device 4 in which the SD card 5 is used is mounted, out of the target related information. good. Specifically, it is recommended to do as follows. The in-vehicle device 4 specifies the main movement range of the vehicle (for example, prefecture, city, town, village, etc.) based on the history information and stores it in the SD card 5. The control system 2 reads the main movement range of the vehicle from the SD card 5 inserted into the card reader 29. The control system 2 selects the target-related information included in the main movement range read from the SD card 5 from among the target-related information stored in the target-related table 251, and stores the selected target-related information in the SD card 5 as difference information.

As a result, when the moving range of the vehicle is specified to a certain extent, the target-related information corresponding to the moving range of the vehicle is stored in the SD card 5, so that the in-vehicle device 4 can issue a notification to the driver. It can be executed without Therefore, by storing only the target-related information corresponding to the movement range of the vehicle in the SD card 5, the control system 2 can ensure that the on-vehicle device 4 notifies the driver, and at the same time, the control system 2 can ensure that the on-vehicle device 4 notifies the driver. The amount of information to be stored can be further suppressed.

In the SD card 5, an image taken by a camera (for example, a drive recorder) attached to the vehicle may be stored by the in-vehicle device 4. For example, the camera may take an image when an accident occurs and store it in the SD card 5. The control system 2 may read and acquire images photographed by a camera from the SD card 5 inserted into the card reader 29. For example, in the control system 2, the acquired image may be displayed on the display unit 27. Thereby, the control system 2 can allow the user to view the image in a favorable manner.

Based on the registration information, invalidation information, detection information, and false detection information acquired from the SD card 5, the control system 2 determines registered target objects and their positions, areas where notification is disabled, and new target objects. An image for specifying the detected position and the position where the target object was erroneously detected may be superimposed on the map and displayed on the display unit 27 for the user to confirm. Since the control system 2 is provided with a display section 27 that is larger than the in-vehicle device 4, registration information and the like can be clearly viewed by the user.

The control system 2 may receive an operation for registering goal-related information from the user via the input unit 28. In this case, the control system 2 stores the received goal-related information in the goal-related table 251 of the HDD 25, and at the same time stores the received goal-related information in the SD card 5 if there is an instruction to store it in the SD card 5. You may. The control system 3 includes an input section 28 with superior operability and a display section 27 with excellent visibility compared to the in-vehicle device 4, so the user can easily register goal-related information. .

In the above description, the information related to the target to be notified to the driver was stored in the target related table 251 as target related information. The target object may or may not be an object. For example, it may be a place where there are no specific objects, such as a public enforcement area.

Note that the HDD 25 and the like that store the goal-related table 251 correspond to the "first storage means" of the present invention. The HDD 25 and the like that store the user ID related table 252 correspond to the "second storage means" and "third storage means" of the present invention. The HDD 25 and the like that store the other table 253 correspond to the "fourth storage means" of the present invention.
