Description

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

An in-vehicle device is known that specifies positional information between a target object and its own vehicle and notifies a driver of information about the specified positional relationship. Examples of in-vehicle devices include radar detectors and the like. A target object may be, for example, a device for measuring vehicle speed. Target objects are often installed in dangerous places where traffic accidents are likely to occur. Therefore, the in-vehicle device can prompt the driver to drive safely in a place where traffic accidents are likely to occur, for example, by informing the driver of the approach to the target object. Thus, informing the driver of the positional relationship between the target object and the own vehicle contributes to safe driving by the driver.

Freshness and accuracy of target position information are important factors for in-vehicle devices. That is, when the position information of the target object is old, the driver is notified at a place where the target object has already been removed, or even though there is a newly installed target object, the position information of the place is not correct. Since there is no notification, the reliability is lowered. Therefore, in a normal in-vehicle device, it is possible to update the position information of the target object even after purchase.

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

Further, Japanese Patent Laid-Open No. 2002-200000 discloses a technique for acquiring new position information updated in another in-vehicle device by receiving position information wirelessly transmitted from another in-vehicle device and storing the received position information in a memory.

JP 2009-266057 A

The device described in Patent Document 1 requires a new communication device for performing wireless communication between the on-vehicle devices, so a method of updating position information by an information terminal is usually adopted. Here, the format and contents of the position information stored in the external non-volatile memory must correspond to the type of the vehicle-mounted device. This is because the format and content of the position information stored in the external non-volatile memory differ depending on the type of vehicle-mounted device. If position information corresponding to different types of in-vehicle devices is stored in the external non-volatile memory, the in-vehicle device cannot use the position information and cannot notify the driver. Therefore, when updating the position information via the information terminal, it is necessary to specify to the information terminal the type of the vehicle-mounted device that uses the external non-volatile memory. However, since the driver usually does not recognize the type of the on-vehicle device in use, it is troublesome to have to confirm the type of the on-board device when updating the position information.

SUMMARY OF THE INVENTION An object of the present invention is to provide a control system, an in-vehicle device, and a program that can reliably store in a storage medium information that can be used for each type of in-vehicle device.

A control system according to a first aspect of the present invention is stored in advance on a storage medium for storing information on a target object used by an in-vehicle device that issues a notification to a driver based on the positional relationship between the target object and the vehicle. Further, the information on the type of the in-vehicle device is read, and the information of the target object corresponding to the read type information of the in-vehicle device is acquired and controlled to be stored in the storage medium.

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

In the first aspect, it is preferable to provide an in-vehicle device that writes the 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 type information of the in-vehicle device is usually not stored in the storage medium, so the user needs to store the type information of the in-vehicle device to be used in the storage medium. When the work of storing the type information of the in-vehicle device is performed manually, it is troublesome for the user to confirm the type of the in-vehicle device. In addition, if the wrong type information of the in-vehicle device is stored in the storage medium, the in-vehicle device cannot normally notify the driver. On the other hand, according to the present invention, since the vehicle-mounted device directly stores the type information of the vehicle-mounted device in the storage medium, the type information of the vehicle-mounted device is stored accurately and reliably. Thus, the control system can reliably store target object information that can be used in the on-vehicle device in 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 in-vehicle device, it is preferable to use a type of target target information that can be used in the in-vehicle device. Even in-vehicle devices having the same hardware may have different target information that can be used. For example, this is the case when the version of the firmware that drives the in-vehicle device is different. Here, by using the type of target target information that can be used by the in-vehicle device as the identification information of the in-vehicle device to be stored in the storage medium, when the target target information that can be used in the in-vehicle device with the same hardware differs. Even so, it is possible to reliably store the target information that can be used by 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, which is information of a different part between the target target information corresponding to the type information of the in-vehicle device read from the storage medium and the already acquired target target information, is acquired. , may be stored in the storage medium. For example, the information amount of the target object may be large, such as when the target object information includes position information, target object type information, 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 reduce the amount of information stored in the storage medium. Therefore, the time required to store information in the storage medium can be shortened.

In the first aspect, the information of the target object within a predetermined area among the information of the target object corresponding to the type information of the in-vehicle device, and the information of the target object within a predetermined area among the already acquired information of the target object It is preferable to acquire difference information from the information of and store it in the storage medium. The control system refines the target object information based on the position of the target object and stores it in the storage medium. For example, when storing information on public enforcement in a storage medium, the storage medium stores information on public enforcement conducted in an area including a location where a vehicle is located and an area including a location through which a vehicle travels to its destination. If so, it is possible to inform the driver of public enforcement information according to the vehicle position. Therefore, in the control system, only the difference information of the target target 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 on the storage medium.

In the first aspect, when history information in which travel positions and travel times of the vehicle are associated with each other is stored in the storage medium, the history information stored in the storage medium is acquired, and the Preferably, history information is deleted from the storage medium. As a result, when the storage medium is repeatedly used in the in-vehicle device, it is possible to prevent the storage capacity from becoming insufficient.

In the first aspect, it is preferable to perform control for displaying the places visited by the vehicle in order on the 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 road actually traveled by the vehicle in chronological order, the user can more intuitively recognize the travel history of the user.

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 the traveling speed of the vehicle at the traveling position. The control system can enhance the user's sense of realism by displaying the image of the target object and the running speed. Therefore, the user can view the travel history as if he or she were there.

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

In the first aspect, in the storage medium, among registration information that is the target target information registered by the user and invalid information that the user instructs to invalidate notification based on the target target information At least one of the registration information and the invalidation information stored in the storage medium may be obtained when at least one of the information is stored. The control system can effectively utilize the acquired registration information and invalidation information. For example, based on the acquired registration information and invalidity information, an image for specifying the target object may be displayed on a map to allow the user to confirm it. This allows the user to visually recognize the registration information and the invalidity 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 place where the target object is not actually installed. When detection information related to information detected when a target object is detected or when at least one of when the in-vehicle device acquires vehicle state information is stored in the storage medium It is preferable to acquire the detection information that has been received. The control system can effectively utilize the acquired detection information or time information. For example, when a target object or a malfunction is detected as the detection information, it is preferable to display an image in which an image for specifying the target object or malfunction is arranged on a map on the display. As a result, the user can visually recognize the detected information well.

In the first aspect, the information acquired from the storage medium is classified by user and stored in a second storage means, and when the information is stored in the storage medium, the user who uses the storage medium is The user may be specified based on the information for specifying the user stored in the medium, and the information corresponding to the specified user may be read from the second storage means and stored in the storage medium. This allows the user to repeatedly use information unique to him/herself in the in-vehicle device. For example, when a plurality of users share a common vehicle-mounted device, each user may own a storage medium in which information for identifying the user is stored. As a result, information unique to each user is stored in the storage medium, and the in-vehicle device can operate based on the information unique to each user.

In the first aspect, when the storage medium is used in the in-vehicle device, the storage medium stores certification information proving that it has been used in the in-vehicle device, and the storage medium stores the certification information. The target object information may be stored on the storage medium only if it is stored. This prevents the target object information from being stored on a storage medium that is not actually used by the in-vehicle device. Therefore, the security of the targeted information can be enhanced, so that 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 preferably includes at least one of travel position and travel time. If the travel position and travel time are stored as proof information, the storage medium is actually used by the in-vehicle device. By using the travel position and travel time as proof information in this way, it is possible to easily confirm that the storage medium is being used by the in-vehicle device. Also, the travel position and travel time can be utilized as information indicating the travel history of the vehicle.

In the first aspect, control is performed to store setting information indicating various settings at the time of operation of the in-vehicle device in the storage medium, and the in-vehicle device at the time of operation is controlled based on the setting information stored in the storage medium. Various settings should be made. As a result, various settings during operation of the in-vehicle device can be changed via the control system.

In the first aspect, a user who uses the storage medium is specified by information for specifying the user stored in the storage medium, and the setting information is stored for each user based on a third storage means, The setting information corresponding to the specified user may be selected and stored in the storage medium.

Since the setting information is classified for each user, the in-vehicle apparatus can be operated according to the settings of each user by using the storage medium storing the setting information unique to each user. For example, when a plurality of users share a common vehicle-mounted device, each user may own a storage medium in which information for identifying the user is stored. Thereby, the user can always drive the in-vehicle device under the desired setting conditions without performing input operation of 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 the other user ID is 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 obtained , the setting information may be acquired from the server and stored in the storage medium. As a result, even if the setting information cannot be obtained from the third storage means due to a failure of the third storage means, the setting information can be restored by inquiring of the server. Therefore, it is possible to save the user the trouble of setting the in-vehicle device again.

In the first aspect, when the setting information is hierarchically organized, by guiding the operation of the control system by the user in hierarchical order, the operation method desired by the user for the in-vehicle device can be obtained. The setting information necessary for operating the in-vehicle device may be specified, and the specified setting information may be stored in the storage medium. Accordingly, the user can reliably specify the setting information required to operate the in-vehicle device in a desired operation method by hierarchically performing the input operation according to the guidance.

In the first aspect, when an inquiry about 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 displayed on the display means. The setting information input by the user in the displayed state may be stored in the storage medium.

Since the user can specify the setting information by querying the control system, the user can operate the in-vehicle device in a desired manner without having detailed knowledge of the in-vehicle device. Since the 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 the input operation many times to change the screen. Therefore, the user can quickly specify desired setting information and store it in the storage medium, thereby operating the in-vehicle apparatus in a desired operation method.

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

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

In the first aspect, among the acquired information of the target object, information of the target object within a main movement range of the vehicle may be stored in the storage medium.

When the range of movement of the vehicle is specified to some extent, the in-vehicle device can notify the driver without any problem if the information of the target object corresponding to the range of movement of the vehicle is stored in the storage medium. can. Therefore, by storing only the information of the target object corresponding to the range of movement of the vehicle in the storage medium, the control system can reliably notify the driver by the in-vehicle device, and at the same time, the information stored in the storage medium amount can be suppressed.

In the first aspect, when an image captured in a predetermined case by a camera provided in the vehicle is stored in the storage medium, the image stored in the storage medium may be acquired. This allows images to be provided to the user at the control system.

This allows the driver to recognize advertisement information about facilities, etc., located near the vehicle. In this way, the in-vehicle device not only notifies the target object but also provides the driver with additional information based on the position of the vehicle so that the driver can 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 using the storage medium on the display means when the usage period of the in-vehicle device has passed a predetermined period. should be done. Thereby, the control system can notify the user when it is time to replace the in-vehicle device and prompt the user to purchase a new in-vehicle device.

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

In the first aspect, it is preferable to provide display means having a larger display area than the display means provided in the in-vehicle device. In many cases, a display provided in an in-vehicle device cannot be enlarged due to restrictions on the overall size of the in-vehicle device. Therefore, the user cannot comfortably browse or edit various information managed by the in-vehicle device. On the other hand, the control system of the present invention can comfortably browse and edit various information by providing, for example, a large display with better visibility than the display means provided in the in-vehicle device.

For example, by displaying the history information acquired from the storage medium on the display means, the user can comfortably view the travel history. Further, for example, based on the registration information and the invalidity information acquired from the storage medium, by displaying on the display means an image in which the image for specifying the target object is arranged on the map, the user can receive the registration information and the invalidation information. It can be visually recognized well. Further, for example, the user can easily change the setting information while viewing the display means, so that the in-vehicle apparatus can be easily operated under desired setting conditions. Further, for example, the user can easily register the information of 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. This may be used to register target object information. In this case, it is preferable to register the type of the target object together.

The control unit 41 executes predetermined processing based on information input from the above various input devices (GPS receiver 45, microwave receiver 46, wireless receiver 47, touch panel 49, card reader 52), and outputs A predetermined alarm/message is output using the device (display unit 48, lamp 50, speaker 51). It should be noted that the basic configuration of these can be basically the same as the conventional ones.

Functions of the in-vehicle device 4 of the present 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 implemented by the CPU 42 executing the firmware. The firmware stored in EEPROM 43 can be updated with new firmware stored in SD card 5 . Functions realized by the computer by means of 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 of displaying the latitude, longitude and altitude of the own 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. This is a function of displaying the relative positional relationship between the vehicle position and the target position on the display unit 48 .

The control unit 41 executes processing for realizing each function such as a GPS warning function, a radar wave warning function, and a wireless warning function according to an event that occurs while the standby screen display function or the radar scope display function is being executed.

The GPS alarm function uses both the target position (latitude and longitude) stored in the SD card 5 and the current position (latitude and longitude) detected by the GPS receiver 45 during execution of the standby screen display function or the radar scope display function. When the obtained distance reaches the predetermined approach 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 displayed. This is a function of reading the voice data obtained and outputting an approach warning voice from the speaker 51 to notify the approach.

Such targets include fixed speed measurement devices (including speed measurement devices that emit radar waves (microwaves) such as radar and speed measurement devices that do not emit radar waves such as loop coils), speed limit switching Point, control area, checkpoint area, parking monitoring area, N system, traffic monitoring system, intersection monitoring point, traffic signal disregarding control system, police station, accident-prone area, vehicle-targeting-prone area, sharp/continuous curve (highway), Junction/merging point (highway), ETC lane advance guidance (highway), service area (highway), parking area (highway), parking area (highway), highway oasis (highway), smart interchange (highway) Road), PA / SA gas station (highway), tunnel (highway), highway radio reception area (highway), prefectural border announcement, roadside station, view point parking etc. The latitude and longitude information shown, the information indicating the type of target object, the schematic diagram or photograph data displayed on the display unit 48, and the audio data of the audio output from the speaker 51 are associated with each other, and stored in the SD card 5. It is managed by the target related table 251 (see FIG. 6).

For example, during execution of the standby screen display function or the radar scope function, the distance between the loop coil, which is the target object, and the own vehicle becomes either 2 km, 1 km, or 500 m, which is the proximity warning distance stored in the SD card 5. In this case, the data of the schematic diagram or the photograph of the target loop coil is read from the SD card 5 and displayed on the display unit 48, and the audio data stored in the SD card 5 is read and the alarm sound is output from the speaker 51. to output the approach notification.

The radar wave warning function is activated when the microwave receiver 46 detects a signal corresponding to microwaves in the 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 for displaying an alarm screen on the display 48 and outputting an alarm sound from the speaker 51 .

The radio alarm function is a function of issuing an alarm so as not to hinder the movement of the emergency vehicle or the like when the radio receiver 47 receives the radio signal emitted by the emergency vehicle or the like. In the radio alarm function, control radio, car location radio, digital radio, special radio, station active radio, police phone, police activity radio, tow radio, helicopter radio, fire helicopter radio, firefighting radio, emergency radio, expressway radio , security radio frequencies, etc., and when a radio signal is received at the scanned frequency, a schematic diagram indicating that the radio signal corresponding to the frequency stored in the SD card 5 for each radio type has been received is displayed on the alarm screen. is displayed on the display unit 48, the audio data stored in the SD card 5 for each wireless type is read out, and an alarm sound indicating the wireless type is output from the speaker 51. FIG.

Details of the information stored in the SD card 5 will be described with reference to FIGS. 3 and 4. FIG. As shown in FIG. 3, the SD card 5 stores (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 described in detail below.

(1) A user ID is identification information for identifying a 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.) to 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 exclusively for himself/herself. 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) The type information is identification information for identifying the type of the 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 (eg, "XXX-1") and the version of the firmware that drives the in-vehicle device 4 (eg, "Ver.1"). Therefore, even if the model number of the in-vehicle device 4 is the same, if the firmware that drives the in-vehicle device 4 is different, different type information is assigned. 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 by the in-vehicle device 4 .

There are two methods for storing the type information in the SD card 5 as follows. The first method is a method in which the manufacturer stores the type information when the SD card 5 is shipped. When the SD card 5 is pre-enclosed with the in-vehicle device 4, type information corresponding to the enclosed in-vehicle device 4 is pre-stored in the SD card 5 by the manufacturer. A second method is a method in which the in-vehicle device 4 stores the type information in the SD card 5 . When a general-purpose SD card is purchased and used, the vehicle-mounted device 4 stores the type information in the SD card 5 when the SD card 5 is inserted into the vehicle-mounted device 4 for the first time. Also, when the firmware that drives the in-vehicle device 4 is updated, the type information is also updated. In this case, the in-vehicle device 4 overwrites 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, when 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 . A control unit 41 (see FIG. 3) of the in-vehicle device 4 is driven based on firmware stored in the EEPROM 43 . When the type information stored in the SD card 5 is different 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 update by

Although the details will be described later, the various types of information that the in-vehicle device 4 acquires from the server 3 via the SD card 5 differ for each type of in-vehicle device 4 . This is because different types of firmware have different types of information that can be processed. The server 3 provides firmware to the in-vehicle device 4 as necessary, manages various types of information that can be processed by each firmware, and provides the information to the in-vehicle device 4 via the control system 2 . Based on the type information stored in the SD card 5, the control system 2 determines various types of information that can be processed when the in-vehicle device 4 using the SD card 5 is driven based on the firmware, and outputs various types of appropriate information. is stored in the SD card 5. For this reason, the in-vehicle device 4 stores the type information corresponding to its own model number and firmware in the SD card 5 so that various types of information that can be processed are reliably stored in the SD card 5 .

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

(3) The target-related information is information related to the target to be notified to the driver. Target-related information includes GPS information, image information, and enforcement information. The GPS information is information in which information indicating the type of target is associated with latitude and longitude indicating the position of the target. 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. The crackdown information is information in which the contents of the public crackdown announced by each prefectural police station are associated with the location, date and time of the public crackdown.

The in-vehicle device 4 obtains the distance between the current position of the vehicle and the target object by referring to the position information of the own vehicle detected by the GPS receiver 45 and the GPS information stored in the SD card 5 . When the obtained distance becomes a predetermined approach warning distance, the in-vehicle device 4 refers to the image information corresponding to the target object type information associated with the position of the target object, and corresponds to the approaching target object. Identify schematics and photographs to be used. The in-vehicle device 4 notifies the driver that the vehicle has approached the target by displaying the specified schematic diagram or photograph on the display unit 48 (see FIG. 2). The in-vehicle device 4 also refers to the crackdown information stored in the SD card 5 to determine whether or not the vehicle has entered a place where a public crackdown is being carried out. The in-vehicle device 4 displays the details of the public crackdown on the display unit 48 when the vehicle enters a place where the crackdown is being held. Thus, the in-vehicle device 4 notifies the driver that public enforcement is being carried out near the vehicle.

(4) Registration-related information includes registration information, invalidation information, detection information, and false detection information. The registered information is information in which information indicating the type of the target registered by the user is associated with latitude and longitude indicating the position of the target. For example, the user inputs into the in-vehicle device 4 via the touch panel 49 a point where a mobile orbis frequently appears or a point where an orbis is newly 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 registration information, the in-vehicle device 4 displays on the display unit 48 a screen notifying that the vehicle has approached the registered position, and outputs an alarm sound from the speaker 51. Realize the GPS alarm function.

The invalid information is latitude and longitude information indicating a position at which notification by the in-vehicle device 4 is invalidated. For example, the user inputs into the in-vehicle device 4 via the touch panel 49 a point, such as an automatic door, at which the in-vehicle device 4 issues a warning notification using the radar wave warning function even though no target is installed. The in-vehicle device 4 stores the input information in the SD card 5 as invalid information. The in-vehicle device 4 has the GPS warning function and 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. Do not notify the driver by the radar wave warning function.

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

The erroneous detection information is information indicating the latitude and longitude of the location, which is stored when the vehicle-mounted device 4 detects microwaves but the target is not actually set. In the erroneous detection information, the latitude and longitude indicating the position where the in-vehicle device 4 gave the erroneous alarm and the time when the erroneous alarm was given are associated. For example, even if the in-vehicle device 4 detects microwaves and notifies the user, if the user determines that the target object is not actually installed, the in-vehicle device 4 via the touch panel 49 Input that it is a false detection. The in-vehicle device 4 stores the input information in the SD card 5 as erroneous detection information. When the vehicle approaches the position indicated by the erroneous detection information, the in-vehicle device 4 does not notify the driver by the GPS warning function and the radar wave warning function even if the target object is installed nearby.

Note that the registration information, invalidity 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 entered registration information, invalidity 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 obtained by the in-vehicle device 4 at predetermined intervals when a dedicated connector provided in the vehicle is connected to the OBD connector 53 (see FIG. 2). The in-vehicle device 4 associates the obtained OBD information with the obtained time and stores it in the SD card 5 . Based on the acquired OBD information, the in-vehicle device 4 calculates engine speed, engine load factor, throttle opening, fuel flow rate, cumulative fuel consumption, instantaneous fuel consumption, average fuel consumption, average fuel consumption on ordinary roads, average fuel consumption on highways, lifetime fuel consumption, Lifetime fuel consumption, water temperature, speed, number of revolutions, etc. can be specified. The in-vehicle device 4 can also display various types of information specified based on the OBD information on the display unit 48 while displaying the standby screen on the display unit 48 .

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

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

The store advertisement image information is information in which latitude and longitude indicating the position of the predetermined store and an image for advertising the predetermined store are associated with each other. The in-vehicle device 4 displays an image for advertising the predetermined store on the display unit 48 when the vehicle approaches the predetermined store. This makes it possible to advertise the store 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 passed a predetermined period. The usage period is calculated as described in (9) below. Thus, the in-vehicle device 4 can prompt the driver to purchase a new in-vehicle device 4 . 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. Alternatively, it may be an image for explaining how to use the in-vehicle device 4 conveniently.

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

(8) The setting information is information for specifying driving conditions of the in-vehicle device 4 . The setting information includes a plurality of setting items. For example, as setting items related to alarm settings, 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), and the like. The setting items included in the setting information are changed for 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 when the in-vehicle device 4 is to be used. The usage 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 usage date and time in the SD card 5 as usage start time information. The vehicle-mounted device 4 can determine whether or not the SD card 5 is used for the first time by determining whether or not use start time information is stored in the inserted SD card 5.例文帳に追加The usage start time information is used when calculating the usage period of the in-vehicle device 4 when the control system 2 and the in-vehicle device 4 determine whether or not to display the sales advertisement image.

The electrical configuration of the control system 2 will be described with reference to FIG. The control system 2 is provided with a control unit 21 that performs main control. The control unit 21 is composed of 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. , an input unit 28 including 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 described. The HDD 25 stores a target related table 251 (see FIG. 6), a user ID correspondence table 252 (see FIG. 7), and an other table 253 (see FIG. 8). Each piece of information will be described in detail below.

The target relation table 251 will be described with reference to FIG. The target-related information acquired by the control system 2 from the server 3 via the network 6 is stored in the target-related table 251 for each type of information. Each piece of 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, as the GPS information corresponding to the type information "XXX-1 (Ver.1)", "Ver.1-1" (updated date: 2011/01/05), "Ver.1-2" (updated date: 2011/03/15) and "Ver.1-3" (update date: 2011/05/15) are stored. Therefore, three pieces of GPS information corresponding to the type information "XXX-1 (Ver.1)" were created in the server 3 in the past and made public. On the other hand, as enforcement information corresponding to the type information "XXX-1 (Ver.1)", "Ver.1-1" (updated date: 2011/01/01) "Ver.1-2" (updated date: 2011 /03/01) "Ver.1-3" (updated date: 2011/05/01) and "Ver.1-4" (updated date: 2011/07/01) are stored. This means that four pieces of control information corresponding to the type information "XXX-1 (Ver.1)" were created in the server 3 in the past and made public. Public crackdown information tends to be frequently announced by prefectural police stations, so it is updated more frequently than other information. Also, in FIG. 6, target-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 described with reference to FIG. The user ID correspondence table 252 contains information (type information, registration-related information (registration information, invalid information, detection information, false detection information), OBD information, history information, setting information) read from the SD card 5 by the control system 2. are stored for each user ID. For example, in FIG. 7, the information read from the SD card 5 with the user ID "ichiro" and the information read from the SD card 5 with the user ID "hanako" correspond to the respective user IDs. It is stored with

The other table 253 will be described with reference to FIG. The other information (standby image/sound 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 in the other table 253 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 .

A control first 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, the SD card 5 inserted into the card reader 29 (see FIG. 5) stores target-related information, registration-related information, other information, and setting information as necessary. The control first main process starts when the control unit 21 executes the program stored in the HDD 25 .

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

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 the 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 has been used in the in-vehicle device 4 even once, the history information is stored in the SD card 5 . Therefore, when the history information is not stored in the SD card 5, in order to prevent the target-related information from being stored in the SD card 5 that is not actually used, the subsequent processing is not performed, and the processing returns to S11. .

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

Further, the control system 2 determines whether or not the SD card 5 is actually used in the in-vehicle device 4 by checking whether history information is stored in the SD card 5 or not. This makes it possible to easily confirm that the SD card 5 is being used by the in-vehicle device 4 . In addition, since the history information can be used not only as a travel history of the vehicle but also for determining whether the SD card 5 is actually used in the in-vehicle device 4, the SD card 5 is It is efficient because it does not require additional information to prove that it is used in

Incidentally, in the present invention, for example, in the case where the paid goal-related information is stored only in a specific SD card 5, it may be determined whether or not to store the goal-related information in the SD card 5 based on other 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 the storage of the goal-related information in the SD card 5 is permitted.

If it is determined in S15 that the history information is stored in the SD card 5 (S15: YES), the control unit 21 performs a process of reading the history information stored in the SD card 5 (history reading process (see FIG. 11). )) is executed (S17). The history reading process will be described with reference to FIG. 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).

By reading history information from the SD card 5 and storing it in the HDD 25, the control system 2 displays the history information on the display unit 27 (see FIG. 5), or reads the history information via the input unit 28 (see FIG. 5). can be edited. Since the display unit 48 and the touch panel 49 (see FIG. 2) provided in the in-vehicle device 4 are smaller than the display unit 27 and the input unit 28 of the control system 2, the user can use the in-vehicle device 4 to browse history information. and editing cannot be performed comfortably. On the other hand, since the control system 2 stores the history information in the HDD 25, the history information can be browsed through the display unit 27, which has better visibility than the in-vehicle device 4, and the input unit 28, which has excellent operability, can be used. Since it becomes possible to edit the history information via the user, the user can comfortably browse and edit the history information.

Also, the history information stored in the SD card 5 is deleted after being read by the control system 2 . As a result, when the SD card 5 is repeatedly used in the in-vehicle device 4, it is possible to prevent the storage capacity of the SD card 5 from running out due to accumulation of history information.

After the history reading process (S17, see FIG. 11) ends, as shown in FIG. 9, the control unit 21 reads 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 section 21 displays a selection screen for information to be stored in the SD card 5 on the display section 27 .

A selection screen 271 displayed on the display unit 27 will be described with reference to FIG. The selection screen 271 has an area 272 for displaying the type information and the user ID stored in the SD card 5, an area 273 for displaying the sales advertisement image, and a check box area 274 for selecting information to be stored in the SD card 5. is provided. In the check box area 274, target-related information (GPS information, image information, control information), registration-related information (registration/invalidation information, detection/erroneous detection information), setting information, other information (standby screen/audio information, store Advertisement information, sales advertisement information), and checkboxes for selecting whether or not to share. The user selects the information desired to be stored in the SD card 5 by checking the check box, and selects the OK button. As a result, the designated information is stored in the SD card 5 by the process described later. Note that when the user specifies enforcement information among the target-related information, the user also selects one or a plurality of specific regions from a list box for specifying regions. This designates the implementation area of public enforcement information. 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 own SD card 5 .

As shown in FIG. 9, the control unit 21 acquires use 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 usage period has passed 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 usage period has passed the predetermined period (S25: YES), the in-vehicle device 4 has been used for a long time. The control unit 21 acquires from the server 3 via the network 6 the sales advertisement image information corresponding to the type information read in S19 and having the latest update date and time. The server 3 creates sales advertisement information for advertising a new model of the in-vehicle device 4 and updates the sales advertisement information at a cycle shorter than the predetermined period. Control unit 21 stores the acquired sales advertisement image information in other table 253 (see FIG. 8) of HDD 25 . The control unit 21 selects the image data of the sales advertisement 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 on new products such as a new in-vehicle device 4 different from the in-vehicle device 4 specified by the type information, and information on the in-vehicle device 4 such as optional products for the in-vehicle device 4 specified by the type information. contains images to promote products or services related to The sales advertisement image also includes a function list of the in-vehicle device 4 to be advertised. Accordingly, the control system 2 can notify the user when it is time to replace the in-vehicle device 4 and prompt the user to purchase a new in-vehicle device 4 . The process proceeds to S29.

Assume that the user checks the check box 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 processing for storing the information of the specified item in the SD card 5 as follows.

As shown in FIG. 10, if the user selects any item of the goal-related information and other information and selects the OK button (S31: YES), A process (first storage process, see FIG. 12) of storing the information of the designated item in the SD card 5 is executed (S33). After the first storage process ends, the process proceeds to S35. On the other hand, if the user has specified neither the goal-related information nor the other information (S31: NO), the process proceeds to S35.

The first storage processing will be described with reference to FIG. In the following description, it is assumed that the user designates image information among the target-related information as information to be stored in the SD card 5 . However, similar processing is performed when information other than image information is specified among the target-related information and other information. By inquiring of the server 3, 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 (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 image information acquired in S71 with the type information and the update date and time, and stores them in the target relation table 251 (see FIG. 6) of the HDD 25 (S75). The control unit 21 calculates difference information, which is information on 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 a temporary area of the SD card 5 (S79). The process proceeds to S81.

The in-vehicle device 4 reconstructs 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 ready 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 the difference information and storing it in the SD card 5 . For example, as described above, when image information is designated as target-related information, the data amount of image information to be stored in the SD card 5 is large because the data amount of image information is generally large. Therefore, if the image information is stored in the SD card 5 as it is, it may take a long time to store it. If a plurality of pieces of information are specified by the user, the amount of data of the information will be even greater, and the time required for storage will be 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 in the SD card 5. FIG.

Further, the control system 2 acquires information corresponding to the same type information from the server 3 and stores it in the SD card 5 so that the vehicle-mounted device 4 can reliably 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 (eg, "XXX-1") and information indicating the version of the firmware (eg, "Ver.1"). 4 are driven based on different firmware, information that can be used by each in-vehicle device 4 can be reliably acquired from the server 3 and stored in the SD card 5. - 特許庁Therefore, the in-vehicle device 4 can reliably notify the driver by referring to the SD card 5 .

In addition, when the enforcement information is specified by the user among the target-related information, the area 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 specified area and the enforcement information of the specified area stored in the SD card 5 and stores it in the temporary area of the SD card 5 . In this way, the control system 2 can narrow down the control information according to the specified area and store it in the SD card 5. FIG. Thereby, the control system 2 can further suppress the amount of information stored in the SD card 5 . It should be noted that the driver only needs to be notified of information on public enforcement in the area including the current position of the vehicle and in the area through which the vehicle passes by on the way to the destination. Therefore, if the enforcement information of these regions is stored in the SD card 5, the in-vehicle device 4 can surely notify 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 server 3 updates the image information. not (S73: NO). In this case, since there is no need to store the image information in the SD card 5, the process proceeds to S81.

In S81, it is determined whether or not all the items specified by the user via the selection screen 271 (see FIG. 16) have been processed (S81). If there are items that have not been processed (S81: NO), the process returns to S71. On the other hand, if all the items of the target-related information and other information specified by the user have been processed (S81: YES), the first storage process ends, and the control first main process (see FIG. 10) ).

In S35 of FIG. 10, it is determined whether or not 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 none of the items of the registration-related information is checked by the user (S35: NO), the control unit 21 determines whether the registration-related information and the OBD information are stored in the SD card 5 (S39). ). If the registration-related information and the 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 the 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 the 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 , FIG. 14) is executed (S37). After the process ends, the process proceeds to S43. The details of the second memory processing will be described later.

Read processing will be described with reference to FIG. The control unit 21 reads out the user ID stored in the SD card 5 (S91). The control unit 21 reads registration-related information (registration information, invalidity information, detection information, and false detection information) and OBD information stored in the SD card 5 (S93). Since time is associated with the detection information, the false detection information, and the OBD information, the associated time is also read. The control unit 21 associates the registration-related information and the OBD information (including the 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 processing ends, and the processing returns to the control first main processing (see FIG. 10).

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

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

The second storage processing will be described with reference to FIG. The control unit 21 reads the user ID stored in the SD card 5 (S101). The control unit 21 acquires the 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 control first main process (see FIG. 10).

By executing the above processing, the user can drive the in-vehicle device 4 using the registration-related information unique to the user. For example, when a plurality of users share a common in-vehicle device 4, each user may own an SD card 5 in which a user ID for identifying the user is stored. As a result, registration-related information unique to each user is stored in the SD card 5, 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 does not specify the setting information (S43: NO), the control unit 21 determines whether 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. When setting information is stored in the SD card 5 (S45: YES), the control section 21 executes a process of reading the setting information (reading process, see FIG. 13) (S47). As shown in FIG. 13, the control unit 21 reads the user ID stored in the SD card 5 (S91). The control unit 21 reads the setting information stored in the SD card 5 (S93). The control unit 21 associates the user ID with the setting information and stores it in the user ID correspondence table 252 (see FIG. 7) of the HDD 25 (S95). The read processing ends, and the processing returns to the control first main processing (see FIG. 10). As shown in FIG. 10, when the reading process is finished, the control unit 21 associates the user ID with the setting contents and transmits them to the server 3 via the network 6 (S49). The server 3 associates the received user ID with the setting information and stores them in the database.

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

The third storage processing will be described with reference to FIG. The control unit 21 reads out the user ID stored in the SD card 5 (S111). Subsequently, 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 to 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 setting information has been successfully read (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. By storing, the in-vehicle device 4 can be operated under the conditions set by each user. For example, when a plurality of users share a common in-vehicle device 4, each user may own an SD card 5 in which a user ID for identifying the user is stored. Accordingly, the user can always operate the in-vehicle device 4 with desired settings without having to perform operation setting input operation 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, thereby obtaining the setting information corresponding to the user ID. It is obtained from the server 3 (S117). The control system 2 has a function of transferring 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). Therefore, the setting information is stored in the server 3 in association with the user ID. The server 3 can transmit setting information corresponding to the notified user ID to the control system 2 in response to an inquiry from 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 setting information cannot be obtained from the user ID correspondence table 252 due to a failure of the HDD 25 or the like, the control system 2 can reliably store the setting information in the SD card 5 by inquiring the server 3. can do. This saves the user the trouble of setting the in-vehicle device 4 again when the HDD 25 fails.

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

As shown in FIG. 15, in the third storage process, the control unit 21 acquires the user ID of the user selected at the same time when the user designates 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 it is.

In the above description, by storing the setting information corresponding to the designated user ID in the SD card 5, the setting information used in the in-vehicle device 4 of a specific user is shared by other users. However, the shared information is not limited to setting 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 described above, the control system 2 executes the first control process, so that the user can transfer the target-related information usable by the in-vehicle device 4 to the SD card without performing any specifying operation on the control system 2 . 5 can be stored. By referring to the SD card 5 storing the target-related information, the in-vehicle device 4 can reliably perform the notification regarding the target object. Since the user does not need to recognize in advance the information for specifying the information that can be used in the in-vehicle device 4, for example, the type information of the in-vehicle device 4, updating the target-related information stored in the SD card 5 is performed. It can be done quickly and easily.

The control second main process executed in the control unit 21 of the control system 2 will be described with reference to FIGS. 17 to 21. FIG. In the control second main process, the setting information of the in-vehicle device 4 input by the user via the input unit 28 is acquired, and the process of storing it in the user ID correspondence table 252 (see FIG. 7) of the HDD 25 is executed. 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 first control main process described above. When the user inputs an instruction to start inputting the setting information, the control section 21 executes the program stored in the HDD 25 to start the control second main process.

When the control second 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 that allows selection of the input method of the setting information. There are the following three methods for inputting setting information. When inputting setting information, the user selects one of the methods and performs an input operation.
(1) A method of specifying items of setting information desired by the user by hierarchically guiding the user's operations, and changing the setting contents.
(2) A method of specifying the most appropriate setting information item according to a question from the user based on the FAQ format and changing the setting content.
(3) A method of displaying items of setting information desired by the user in order and changing the setting contents (conventional method)

FIG. 18 shows setting information 61 of the in-vehicle device 4 . In this manner, the setting information 61 includes a large number of items, and each item is organized hierarchically. Here, in the conventional method of changing the setting contents of a desired item via the in-vehicle device 4, the touch panel 49 is usually operated to scroll and display each item until the desired item is displayed on the display unit 48. do. After the target item is displayed on the display unit 48, the setting contents of the item displayed on the display unit 48 are changed. Therefore, in the conventional method, not only does it take time to display the desired item on the display unit 48, but the desired item is easily overlooked. In addition, since there are so many items of setting information, the user may not know which item should be changed 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. are hierarchically displayed (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. It should be noted that the control unit 21 preferably acquires 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 the setting information 61 in the HDD 25 in association with the type information. Further, when the control second main process is started, the control unit 21 reads the type information stored in the SD card 5 inserted in the card reader 29, and requests the corresponding setting information 61 from the server 3. 3 and store the setting information 61 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. Hereinafter, description will be made with reference to screen transition 65 in FIG. As shown in FIG. 19 , the control unit 21 first displays a “setting” button 62 on the display unit 27 . When detecting that the user has selected the "setting" button 62, the control unit 21 displays the "radar", "GPS", and "wireless" buttons corresponding to items in the hierarchy below "setting". 27. Subsequently, when detecting the selection of the "radar" button 63 by the user, the control unit 21 selects "I cancel", "I cancel sound", and "opposite cancel" corresponding to items in the hierarchy below "radar". button is displayed on the display unit 27 .

"I Cancel" is a function that automatically registers the GPS position information when passing through a place where an automatic door causes a false alarm. "I cancel sound" is a function of outputting a voice saying "Cancellation is in progress" during I cancellation. "Opposite cancellation" is a function that cancels the radar wave reception warning on the opposite lane of the new H system registered in the GPS information and the radar type Orbis Point. Subsequently, when detecting selection of the “oppose cancel” button 64 by the user, the control unit 21 displays “ON” and “OFF” buttons corresponding to the setting contents for “oppose cancel”. ON/OFF of the opposite cancel function is switched by detecting selection of one of the "ON" and "OFF" buttons by the user.

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

By performing the above-described processing, the user can hierarchically perform input operations according to guidance, so that the user can easily specify items of setting information 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 input operation for selecting the method (2) has been performed by the user (S123: NO, S133: YES), the control unit 21 selects items of setting information in response to the user's inquiry. identify and accept changes to the settings. As a result, even if the user does not know how to change the setting items to drive the in-vehicle device 4 with the desired driving method, the user can change the setting contents of the optimum items. can. In the HDD 25 of the control system 2, character string information prompting 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 unit 27 . When the user inputs a plurality of keywords, character strings associated with all the keywords are selected and displayed on the display unit 27 . It should be noted that the control unit 21 may preliminarily acquire combinations of character strings and keywords corresponding to the in-vehicle devices 4 having different type information from the server 3 and store them in the HDD 25 in association with the type information. When starting the control second main process, the control unit 21 reads the type information stored in the SD card 5 inserted in the card reader 29, and requests the server 3 for a combination of the corresponding character string and keyword. It is preferable to obtain the character string and the keyword 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.

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

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

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

The display unit 27 displays information about the setting information item that is most suitable 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 trouble of specifying the item to be changed by performing the input operation many times to change the screen. Therefore, the user can drive the in-vehicle device 4 by the desired driving method by quickly specifying the desired item.

Note that when the user performs an input operation to select the method (2), the control unit 21 may perform the following process instead of the above-described S135 to S145. A web system for realizing a FAQ search system is provided on a server on the Internet (for example, the server 3 may be used). The user uses the control system 2 to launch a browser and access this FAQ search page. A user inputs a keyword or the like on 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 according to the search result corresponding to the keyword. 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, when it is detected that the input operation for selecting the method (3) is performed by the user (S133: NO), the setting information 61 (see FIG. 18) is displayed according to the input operation via the input unit 28 by the user. are sequentially displayed on the display unit 27 (S147). Assume that the user performs an input operation to change the setting contents of the item being displayed. The control unit 21 acquires the input setting content (S149). The control unit 21 associates the items and setting contents of the acquired setting information with the user ID acquired in S121, and stores them as setting information in the user ID correspondence table 252 of the HDD 25 (S151). The control unit 21 associates the user ID with the items and the setting contents, and transmits them to the server 3 via the network 6 (S161). The server 3 associates the received user ID, item, and setting content, and stores them in the database. The control second 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 the touch panel 49 provided in the in-vehicle device 4 cannot be enlarged due to restrictions on the overall size of the in-vehicle device 4 . Therefore, the user cannot easily change the settings via the in-vehicle device 4 . On the other hand, the control system 2 is provided with an input unit 28 superior in operability and a display unit 27 superior in visibility as compared with the in-vehicle device 4 . Therefore, the user can easily change the settings. In-vehicle device 4 operates based on setting information stored in SD card 5 . Therefore, the control system 2 can change the drive 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 drive conditions.

A travel simulation function provided in the control system 2 will be described with reference to FIG. 22 . Assume that it is detected that the user has input an instruction to start the driving simulation through the input unit 28 together with the user ID. 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 a simulation image 300 shown in FIG. 22 on the display unit 27 based on the read history information, and starts the running 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 so as to determine the area specified by the latitude and longitude indicating the driving position of the vehicle in the history information. 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 traveling position of the vehicle in the history information. Also, a mark 302 is displayed at the point indicated by the latitude and longitude to indicate that the vehicle has passed through the point. Note that the marks 302 are displayed on the map image 301 in order of travel times included in the history information. As a result, the user can check the route of the road actually traveled by the vehicle in chronological order, so that the user can more intuitively recognize the travel history of the user. In addition, the display unit 27 provided in the control system 2 is larger and has better visibility than the display unit 48 provided in the in-vehicle device 4, so the user can comfortably view the travel 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 traveling time of the vehicle among the read OBD information to identify the traveling speed of the vehicle. The identified travel speed is displayed as a speed display 305 superimposed on the map image 301 .

In addition, the control system 2 updates the GPS information stored in the target relation table 251 (see FIG. 6) to a time earlier than the running time included in the history information and closest to the running 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 becomes the approach warning distance, the image information 304 corresponding to the approaching target is read from the target relation table 251 and displayed superimposed on the map image 301 . As described above, the control system 2 can display an image showing the target object that was actually set on the road at the time the vehicle traveled, superimposed on the map image 301 . The control system 2 can also display the travel speed overlaid on the map image 301 together with the image of the target object. These allow the user to experience a highly realistic driving simulation, so that the user can view the driving history as if he or she were there.

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

In-vehicle main processing executed in the control unit 41 of the in-vehicle device 4 will be described with reference to FIG. In the in-vehicle main process, the process of driving based on the information stored in the SD card 5 is executed. When the vehicle starts running, the control unit 41 executes the program stored in the EEPROM 43 to start the in-vehicle main processing.

When the in-vehicle main process is started, first, the control unit 41 determines whether or not the SD card 5 is inserted in 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, so the process returns to S181. When the SD card 5 is inserted into the card reader 52 (S181: YES), the control unit 41 determines whether or not 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 in the card reader 52 is being used for the first time, and the information necessary for notifying the driver is stored. may 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. By inserting the SD card 5 storing the type information 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 process, FIG. 9). , see FIG. 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 must 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. Also, if the wrong type information of the in-vehicle device 4 is stored in the SD card 5, the in-vehicle device 4 cannot perform notification processing to the driver. On the other hand, the in-vehicle device 4 can store its own type information in the SD card 5 when the type information is not stored in the SD card 5 . As a result, the type information of the in-vehicle device 4 is stored in the SD card 5 accurately and reliably. Therefore, the control system 2 can reliably store information that can be used by 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.

When the type information stored in the SD card 5 differs from its own type information, the in-vehicle device 4 overwrites the SD card 5 with its own type information and does not store it. As a result, information stored in the SD card 5 can be prevented 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). When 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). As a result, the in-vehicle device 4 can be driven based on the setting information stored in the SD card 5 . The process proceeds 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. FIG. The process proceeds to S191.

The control unit 41 determines whether the user has input an instruction to start notification to the driver via the touch panel 49 (see FIG. 2) (S191). If the user has not input an instruction to start notification to the driver (S191: NO), the process returns to S191. On the other hand, if the user has input an instruction to start notification (S191: YES), the control unit 41 first acquires usage start time information stored in the SD card 5. FIG. 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 equal to or 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 the other information stored in the SD card, and displays the sales advertisement. Read image data. The control unit 41 displays the read image data of the sales advertisement on the display unit 48 (S195). The process proceeds to S197. On the other hand, if the calculated usage period 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 implements the aforementioned 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 the process of storing history information in the SD card 5 (S199). The control unit 41 selects store advertisement image information with the latest update date and time from the other information stored in the SD card 5 . Based on the position of the predetermined shop and the position of the vehicle, the control unit 41 determines whether the distance between the predetermined shop and the vehicle is less than or equal to a predetermined distance (S201). If the distance between the predetermined store and the vehicle is greater than or equal to the predetermined distance (S201: NO), the process proceeds to S205. On the other hand, when the distance between the predetermined store and the vehicle is equal to or less than the predetermined distance (S201: YES), the control section 41 reads the image data of the store advertisement 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 proceeds to S205. By performing the display control described above, the driver can recognize the advertising information regarding facilities and the like located near the vehicle. The in-vehicle device 4 not only notifies the target object but also provides the driver with additional information based on the position of the vehicle so that the driver can obtain various information while driving.

The control unit 41 determines whether or not the driver has input, through the touch panel 49, an instruction to end the notification process regarding the target (S205). If the driver has not input an instruction to end the notification process regarding the target object (S205: NO), the process returns to S199. On the other hand, when 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.

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 processing 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 readable by the control system 2 and information unreadable by the control system 2 . For example, the SD card 5 may have a folder storing information readable by the control system 2 and a folder storing information unreadable 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 the privacy of the user, it is desirable that the history information including the travel position and travel time of the vehicle is not read by the control system 2 . On the other hand, registration-related information is preferably taken into the control system 2 because it is possible to acquire the latest target target information by sharing it with a plurality of people. In this case, history information should be stored in a folder that stores unreadable information, and registration information and invalid information should be stored 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 the 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 in the SD card 5 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 the target in the main movement range of the vehicle in which the in-vehicle device 4 using the SD card 5 is mounted, among the target-related information. good. Specifically, the following should be done. The in-vehicle device 4 identifies the main movement range of the vehicle (for example, prefectures, municipalities, 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 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 movement range of the vehicle is specified to some extent, the target-related information corresponding to the movement range of the vehicle is stored in the SD card 5, so that the in-vehicle device 4 can notify the driver. can be run 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 in-vehicle device 4 notifies the driver. The amount of information to be stored can be further suppressed.

Images captured by a camera (for example, a drive recorder) attached to the vehicle may be stored in the SD card 5 by the in-vehicle device 4 . For example, the camera may take an image and store it in the SD card 5 when an accident occurs. The control system 2 may read and acquire images captured by the camera from the SD card 5 inserted in the card reader 29 . For example, in the control system 2, the obtained image may be displayed on the display section 27. FIG. This allows the control system 2 to allow the user to view the image in a favorable manner.

Based on the registration information, invalidity information, detection information, and erroneous detection information acquired from the SD card 5, the control system 2 determines the registered target object and its position, the area where the notification is invalidated, and the new target object. An image for identifying 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 the display unit 27 that is larger than the in-vehicle device 4, it is possible for the user to visually recognize the registration information and the like.

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

In the above description, the information related to the target to be notified to the driver is stored in the target related table 251 as the target related information. The target object may or may not be an object. For example, it may be a place without specific objects, such as a public control area.

Note that the HDD 25 or the like that stores the target related table 251 corresponds to the "first storage means" of the present invention. The HDD 25 or the like that stores the user ID related table 252 corresponds to the "second storage means" and the "third storage means" of the present invention. In addition, the HDD 25 or the like that stores the table 253 corresponds to the "fourth storage means" of the present invention.
