[0003] [Patent Document 1] JP 2020-60929 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the above technology, the warning speed corresponds to the speed limit of the road, but the vehicle speed at which the driver wants to receive a warning or other notification while driving may change depending on the vehicle's conditions, so it does not necessarily match the speed limit. As a result, there are cases where the notification cannot be given at the timing intended by the driver.

[0005] The present invention has been made in consideration of these points, and has an object to make it possible to provide a notification at a timing that reflects the driver's intention. [Means for solving the problem]

[0006] In a first aspect of the present invention, an electronic device is provided that includes a first acquisition unit that acquires a first set speed that is set based on a speed limit recognized by an imaging unit and imaged from a sign of a road on which a vehicle is located, or identified from map information of the road, a second acquisition unit that acquires a second set speed that is set by a user of the vehicle, and a notification control unit that causes a notification unit to issue a first notification if the speed of the vehicle exceeds the first set speed, and causes the notification unit to issue a second notification that is distinguishable from the first notification if the speed exceeds the second set speed.

[0007] The first set speed may be a set speed obtained by adding a predetermined speed to the speed limit.

[0008] The vehicle may further include a receiving unit that receives one of a plurality of additional speeds as the specified speed, and the first acquisition unit may acquire the first set speed by adding the one additional speed accepted by the receiving unit to the speed limit.

[0009] In addition, the notification unit may have a display unit that displays on a screen a first icon related to the speed limit and a second icon related to the second set speed, and the notification control unit may change a display mode of the first icon when the speed exceeds the first set speed, and change a display mode of the second icon when the speed exceeds the second set speed.

[0010] In addition, the notification control unit may be configured to blink the first icon when the speed exceeds the first set speed, and to blink the second icon when the speed exceeds the second set speed.

[0011] In addition, the notification unit may have a display unit that displays on a screen a first icon related to the speed limit and a second icon related to the second set speed, and the first icon and the second icon may be displayed at separate positions on the screen.

[0012] The display unit may also include a display area for displaying speed information relating to the speed of the vehicle, and the first icon and the second icon may be positioned apart on the screen so as to sandwich the display area.

[0013] Moreover, the first acquisition unit may update the first set speed every time the speed limit recognized by imaging with the imaging unit changes.

[0014] In addition, the second set speed may be equal to or less than the first set speed, and the notification control unit may cause the notification unit to make the first notification when the speed exceeds the first set speed, and may cause the notification unit to make the second notification when the speed exceeds the second set speed but does not exceed the first set speed.

[0015] Furthermore, the notification control unit may cause the notification unit to perform a third notification when the second set speed exceeds the first set speed.

[0016] In a second aspect of the present invention, there is provided a vehicle including the above electronic device and an imaging unit that images the road signs.

[0017] In a third aspect of the present invention, there is provided an alarm control method comprising the steps of: executing a processor: acquiring a first set speed which is set based on a speed limit recognized by an imaging unit by imaging a sign of a road on which a vehicle is located, or which is identified from map information of the road; acquiring a second set speed which is set by a user of the vehicle; and, if the speed of the vehicle exceeds the first set speed, causing an alarm unit to issue a first alarm, and, if the speed exceeds the second set speed, causing the alarm unit to issue a second alarm which is distinguishable from the first alarm.

[0018] In a fourth aspect of the present invention, a program is provided to cause a processor to execute the steps of: acquiring a first set speed which is set based on a speed limit recognized by an imaging unit by imaging a sign on a road on which a vehicle is located, or which is identified from map information of the road; acquiring a second set speed which is set by a user of the vehicle; and, if the speed of the vehicle exceeds the first set speed, causing an alarm unit to issue a first alarm, and, if the speed exceeds the second set speed, causing the alarm unit to issue a second alarm which is distinguishable from the first alarm. Effect of the Invention

[0019] According to the present invention, it is possible to provide an effect that a notification can be given at a timing that reflects the driver's intention. [Brief description of the drawings]

[0020] [Figure 1] FIG. 2 is a diagram showing the configuration of a vehicle V. [Diagram 2] 3 is a schematic diagram showing a display example of a display unit 8. FIG. [Diagram 3] FIG. 13 is a diagram for explaining a plurality of addition speeds. [Figure 4] FIG. 4 is a diagram showing the relationship between the vehicle speed, a first set speed S1, and a second set speed S2. [Diagram 5] 4 is a flowchart showing the operation of the electronic device 10. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0021] <Vehicle Overview> 1 is a diagram showing the configuration of a vehicle V. Here, the vehicle V is a large vehicle such as a truck, but is not limited to this. The vehicle V has an imaging unit 2, a map unit 3, an operation unit 5, a vehicle speed sensor 6, a notification unit 7, and an electronic device 10.

[0022] The imaging unit 2 captures an image of the surroundings of the vehicle to generate a captured image. For example, the imaging unit 2 captures an image of a sign on a road where the vehicle is located to generate a captured image. The imaging unit 2 outputs the generated captured image to the electronic device 10.

[0023] The map unit 3 receives map data from an external server that provides the map data, and stores the received map data. When the map unit 3 receives a notification from the external server that the map data has been updated, the map unit 3 obtains the updated map data.

[0024] The operation unit 5 is a part operated by a driver who is a user of the vehicle. The operation unit 5 includes, for example, a steering key provided on a steering wheel of the vehicle. The driver inputs a set speed of the vehicle via the operation unit 5.

[0025] The vehicle speed sensor 6 detects the speed of the vehicle (hereinafter, also referred to as the vehicle speed). The vehicle speed sensor 6 outputs the detected vehicle speed to the electronic device 10.

[0026] The notification unit 7 has a function of issuing a notification in response to a command from the electronic device 10. Although details will be described later, the notification unit 7 issues a first notification when the vehicle speed exceeds a first set speed (a set speed set based on the speed limit of the road), and issues a second notification that is distinguishable from the first notification when the vehicle speed exceeds a second set speed (a set speed set by the user). The notification unit 7 has a display unit 8 and a sound output unit 9.

[0027] The display unit 8 displays information related to the vehicle status, etc. The display unit 8 has a function of displaying the speed limit of the road on which the vehicle is traveling. The display unit 8 is provided, for example, in the instrument panel of the vehicle, but is not limited thereto, and may be provided, for example, in an information terminal used by the driver.

[0028] 2 is a schematic diagram showing a display example of the display unit 8. The display unit 8 has a display screen 8a that displays text information, icons, etc. The display screen 8a includes a first display area R1, a second display area R2, and a third display area R3.

[0029] The first display area R1 displays the current speed of the vehicle, the remaining fuel, the time, the temperature, etc. In this embodiment, the first display area R1 corresponds to a display area that displays speed information related to the speed of the vehicle.

[0030] A road sign is displayed in the second display area R2. Here, an icon G1 indicating the speed limit of the road on which the vehicle is traveling is displayed. The icon G1 corresponds to an icon related to the speed limit. When the vehicle speed exceeds a first set speed based on the speed limit, the display unit 8 causes the icon G1 to flash for a predetermined time (for example, 5 seconds).

[0031] In the third display area R3, an icon G2 is displayed, which indicates that the user has set a set speed. If the user has not set a set speed, the icon G2 is not displayed in the third display area R3. The icon G2 corresponds to a second icon related to the second set speed. When the vehicle speed exceeds the second set speed, the display unit 8 causes the icon G2 to flash for a predetermined time (for example, 5 seconds).

[0032] The icons G1 and G2 are displayed at positions apart on the display screen 8a. Here, the icons G1 and G2 are positioned at a distance from each other on the display screen 8a, sandwiching the first display region R1 therebetween. Specifically, the icons G1 and G2 are disposed at the corners of the display screen 8a. By positioning the icons G1 and G2 as described above, the driver can easily distinguish the icons G1 and G2 when they flash.

[0033] When the vehicle speed exceeds a set speed, the sound output unit 9 outputs a sound as a first notification or a second notification. The sound output unit 9 is, for example, a speaker provided in the vehicle, and outputs a sound so that the driver can hear it.

[0034] The electronic device 10 recognizes the speed limit of the road on which the vehicle is traveling, and causes the display unit 8 to display the speed limit. For example, the electronic device 10 causes an icon G1 indicating the speed limit to be displayed on the display screen 8a. Furthermore, the electronic device 10 causes the notification unit 7 (specifically, the display unit 8 and the sound output unit 9) to perform a first notification when the vehicle speed exceeds a first set speed set based on the speed limit of the road, and causes the notification unit 7 to perform a second notification when the vehicle speed exceeds a second set speed set by the user. This allows the driver, who is the user of the vehicle, to easily know whether the vehicle speed has exceeded the first set speed or the second set speed.

[0035] <Detailed configuration of electronic devices> The detailed configuration of the electronic device 10 will be described with reference to Fig. 1. The electronic device 10 has a storage unit 20 and a control unit 30.

[0036] The storage unit 20 includes a ROM (Read Only Memory) that stores the computer's BIOS (Basic Input Output System) and the like, and a RAM (Random Access Memory) that serves as a working area. The storage unit 20 is also a large-capacity storage device such as an HDD (Hard Disk Drive) or SSD (Solid State Drive) that stores an OS (Operating System), application programs, and various information referenced when the application programs are executed.

[0037] The control unit 30 is a processor such as a CPU (Central Processing Unit) or a GPU (Graphics Processing Unit). The control unit 30 executes a program stored in the storage unit 20, thereby functioning as a first acquisition unit 32, a reception unit 33, a second acquisition unit 34, a determination unit 35, and a notification control unit 36.

[0038] The first acquisition unit 32 acquires the first set speed set based on the speed limit of the road on which the vehicle is located. For example, the first acquisition unit 32 acquires the first set speed by identifying a sign indicating the speed limit in the captured image generated by the imaging unit 2. In other words, the first acquisition unit 32 acquires the speed recognized by the imaging unit 2 after capturing an image of the sign of the road on which the vehicle is located as the speed limit. The first acquisition unit 32 may acquire the first set speed by identifying the speed limit of the road on which the vehicle is traveling from the map data (map information) stored in the map unit 3. In other words, the first acquisition unit 32 acquires the speed identified from the map information of the road as the speed limit. The first acquisition unit 32 may identify the position of the vehicle using a GPS (Global Positioning System) unit provided in the vehicle, and identify the speed limit of the road on which the vehicle is traveling based on the identified position of the vehicle.

[0039] The first acquisition unit 32 may update the first set speed every time the speed limit recognized by capturing an image by the imaging unit 2 changes. Since the speed limit of a road on which the vehicle travels may change depending on the section, the speed limit recognized by capturing an image by the imaging unit 2 also changes depending on the section of the road. The first acquisition unit 32 may also update the first set speed every time the speed limit identified from the map data changes. Therefore, when the vehicle travels on a road on which the speed limit changes depending on the section, the first acquisition unit 32 will also update the first set speed based on the speed limit. Furthermore, the first acquisition unit 32 may set the first set speed based on the speed limit recognized by capturing an image by the imaging unit 2, and then update the first set speed based on the speed limit identified from the map data when the speed limit identified based on the map data and the vehicle's position information changes. For example, when the vehicle enters a narrow road with a low speed limit from a main road, if the first set speed based on the speed limit recognized by capturing an image by the imaging unit 2 while traveling on the main road continues to be used, the set speed may not be appropriate for the road (narrow road) on which the vehicle is traveling. In such a case, the first set speed can be updated in response to detection of a change in the speed limit from the map data, thereby making it possible to use an appropriate set speed.

[0040] The first acquisition unit 32 sets the speed obtained by adding a predetermined speed to the speed limit as the first set speed. That is, the first set speed is a speed obtained by offsetting the speed limit by the predetermined speed. This allows the speed at which the notification is made to be changed according to the driver's will. The predetermined speed can be set by the driver. For example, the driver adjusts the value of the speed to be added to the speed limit via the operation unit 5. The first acquisition unit 32 may set the speed obtained by subtracting the predetermined speed from the speed limit as the first set speed. In other words, it is also possible to use a negative value as the predetermined speed. When a warning is issued in response to exceeding the first set speed as described later, it is possible to notify the driver in advance that the speed limit is being approached by setting a value lower than the speed limit by the offset amount as the first set speed.

[0041] The reception unit 33 receives an input operation by the driver of the vehicle via the operation unit 5. The reception unit 33 receives one of a plurality of additional speeds as a predetermined speed to be added to the speed limit.

[0042] FIG. 3 is a diagram for explaining a plurality of added speeds. The table shown in FIG. 3 is stored in, for example, the storage unit 20. The plurality of added speeds are, here, a first added speed, a second added speed, and a third added speed, but are not limited thereto. The first added speed is a speed at which the offset amount for the speed limit is set to +2 km / h, the second added speed is a speed at which the offset amount for the speed limit is set to +5 km / h, and the third added speed is a speed at which the offset amount for the speed limit is set to +10 km / h. When the driver selects one of the first added speed, the second added speed, and the third added speed via the steering key of the operation unit 5, the reception unit 33 receives the one added speed selected by the driver.

[0043] The first acquisition unit 32 acquires the first set speed by adding the one additional speed accepted by the acceptance unit 33 to the speed limit. By selecting one additional speed from among the multiple additional speeds in this manner, the first acquisition unit 32 can acquire the first set speed that reflects the driver's intention.

[0044] The second acquisition unit 34 acquires the second set speed set by the driver of the vehicle. For example, the second acquisition unit 34 acquires the second set speed by the acceptance unit 33 accepting the second set speed selected by the driver via the operation unit 5. The driver can set the second set speed not only while the vehicle is traveling but also before starting to travel. In addition, the driver can change the set second set speed at any timing. For this reason, the second acquisition unit 34 acquires the second set speed before starting to travel or while traveling.

[0045] The second set speed is an arbitrary speed set by the driver. For example, when the vehicle travels on a road with a fixed speed limit (for example, an expressway), the driver sets the second set speed to a speed different from the road's speed limit (a speed lower than the road's speed limit). Specifically, when the road's speed limit is 100 km / h, the driver sets 90 km / h as the second set speed. In particular, when the vehicle is a truck, the vehicle is heavy in load and tall, so the driver tends to set the second set speed lower than the first set speed in consideration of safety, etc. On the other hand, when the vehicle is a passenger car and the road is one on which few vehicles travel, the driver may set the second set speed higher than the first set speed. In this way, the driver sets the second set speed to reflect his or her own will.

[0046] The determination unit 35 determines whether the speed of the vehicle (vehicle speed) exceeds a first set speed or a second set speed. For example, the determination unit 35 determines whether the vehicle speed detected by the vehicle speed sensor 6 exceeds the first set speed acquired by the first acquisition unit 32 or the second set speed acquired by the second acquisition unit 34.

[0047] FIG. 4 is a diagram showing the relationship between the vehicle speed, the first set speed S1, and the second set speed S2. Here, it is assumed that the second set speed S2 is smaller than the first set speed S1, and the vehicle accelerates and the vehicle speed gradually increases. The vehicle speed becomes the second set speed S2 at the timing of time t1, and the vehicle speed becomes the first set speed S1 at the timing of time t2. The determination unit 35 determines that the vehicle speed has exceeded the second set speed S2 immediately after time t1, and then determines that the vehicle speed has exceeded the first set speed S1 immediately after time t2. Note that in FIG. 4, the second set speed S2 is smaller than the first set speed S1, but this is not limited thereto. For example, the second set speed S2 may be larger than the first set speed S1. As an example, when the speed limit is 80 km / h, the first set speed S1 is 82 km / h, and the second set speed S2 is 90 km / h.

[0048] The notification control unit 36 ​​controls the notification by the notification unit 7 based on the determination result by the determination unit 35. When the vehicle speed exceeds the first set speed, the notification control unit 36 ​​causes the notification unit 7 to perform a first notification, and when the vehicle speed exceeds the second set speed, the notification control unit 36 ​​causes the notification unit 7 to perform a second notification that is distinguishable from the first notification. That is, when the determination unit 35 determines that the vehicle speed has exceeded the first set speed, the notification control unit 36 ​​causes the notification unit 7 (specifically, the display unit 8 and the sound output unit 9) to perform the first notification, and when the determination unit 35 determines that the vehicle speed has exceeded the second set speed, the notification control unit 36 ​​causes the notification unit 7 to perform the second notification. Since the notification unit 7 performs the first notification and the second notification in a distinguishable manner, the driver of the vehicle can easily determine whether the vehicle has exceeded the first set speed or the second set speed.

[0049] The notification control unit 36 ​​changes the display mode of a first icon (icon G1 in FIG. 2) related to the speed limit as a first notification when the vehicle speed exceeds the first set speed, and changes the display mode of a second icon (icon G2 in FIG. 2) related to the second set speed as a second notification when the vehicle speed exceeds the second set speed. By changing the display mode of the first icon G1 or the second icon G2 in this way, the driver can easily recognize whether the speed has exceeded the first set speed or the second set speed.

[0050] The notification control unit 36 ​​may blink the first icon G1 on the display screen 8a of the display unit 8 when the vehicle speed exceeds the first set speed (time t1 in FIG. 4), and may blink the second icon G2 on the display screen 8a of the display unit 8 when the vehicle speed exceeds the second set speed (time t2 shown in FIG. 4). By blinking the first icon G1 or the second icon G2 in this manner, it becomes easier to identify them on the display screen 8a. In the above description, the notification control unit 36 ​​blinks the first icon G1 and the second icon G2, but is not limited to this. For example, the notification control unit 36 ​​may change the colors of the first icon G1 and the second icon G2.

[0051] The notification control unit 36 ​​may cause the sound output unit 9 to output a sound together with changing the display mode of the first icon G1 and the second icon G2 on the display unit 8. In this case, when the driver is driving without looking at the display unit 8, it is considered that the vehicle speed may have exceeded the set speed, which may trigger the driver to look closely at the display unit 8. Note that the notification control unit 36 ​​may cause the sound output unit 9 to output an alarm as the first alarm and the second alarm instead of changing the display mode of the icons on the display unit 8. That is, the notification control unit 36 ​​may issue a first alarm as the first alarm and a second alarm that is distinguishable from the first alarm as the second alarm. In this case, the volume and type of the sound of the second alarm are different from those of the first alarm.

[0052] From the viewpoint of complying with the speed limit (legal speed limit) posted on road signs, it is desirable that the second set speed is equal to or lower than the first set speed. Therefore, it is desirable that the notification control unit 36 ​​causes the notification unit 7 to perform the first notification when the speed exceeds the first set speed, and causes the notification unit 7 to perform the second notification when the speed exceeds the second set speed but does not exceed the first set speed.

[0053] The notification control unit 36 ​​may cause the notification unit 7 to issue a third notification when the second set speed exceeds the first set speed. If the speed limit of the road on which the vehicle is traveling becomes lower, the first set speed also becomes lower, and therefore a case may occur in which the second set speed exceeds the first set speed. In this case, the third notification can be issued to prompt the driver to change the second set speed. From the viewpoint of distinguishability, it is desirable for the third notification to be in a different notification mode from the first and second notifications, but this is not limited thereto, and the third notification may be in the same mode as the first or second notification. Furthermore, when the second set speed exceeds the first set speed while the vehicle is traveling, the second acquisition unit 34 may update the second set speed to a value that does not exceed the first set speed. In this case, for example, the second acquisition unit 34 may set the second set speed to a value obtained by applying a coefficient of 1 or less that is set in advance by the user to the first set speed. Furthermore, after updating the second set speed, the second acquisition unit 34 returns the second set speed to the initial second set speed set by the user when the first set speed becomes higher than the second set speed before the change that was set by the user.

[0054] In the above description, the user who sets the second set speed is the driver of the vehicle, but this is not limited to this. The manager of the vehicle may set the second set speed. For example, when the manager operates the vehicle remotely, the manager corresponds to the user who sets the second set speed.

[0055] <Processing flow of electronic devices> Fig. 5 is a flowchart showing the operation of the electronic device 10. The flowchart shown in Fig. 5 is executed continuously while the vehicle is running. Note that this flowchart illustrates an example of a process executed when the second set speed is lower than the first set speed.

[0056] First, the first acquisition unit 32 acquires a first set speed that is set based on the speed limit of the road on which the vehicle is located (step S102). For example, the first acquisition unit 32 acquires the first set speed by adding a predetermined speed to the speed limit of the sign captured by the imaging unit 2 or the speed limit identified from the map information of the road.

[0057] Next, the second acquisition unit 34 acquires the second set speed set by the user of the vehicle (step S104). For example, the second acquisition unit 34 acquires the second set speed set by the user via the operation unit 5. The process of step S104 may be executed before the process of step S102.

[0058] Next, the determination unit 35 determines whether the vehicle speed detected by the vehicle speed sensor 6 exceeds the second set speed (step S106). If the vehicle speed exceeds the second set speed in step S106 (Yes), the notification control unit 36 ​​causes the notification unit 7 to issue a second notification (step S108). For example, the notification control unit 36 ​​blinks the second icon G2 on the display screen 8a for a predetermined time (e.g., 5 seconds) and causes the sound output unit 9 to generate a sound. On the other hand, if the vehicle speed does not exceed the second set speed in step S106 (No), the process returns to step S102.

[0059] Thereafter, the determination unit 35 determines whether the vehicle speed exceeds the first set speed (step S110). If the vehicle speed exceeds the first set speed in step S110 (Yes), the notification control unit 36 ​​causes the notification unit 7 to perform a first notification (step S112). On the other hand, if the vehicle speed does not exceed the first set speed in step S110 (No), the process returns to the process of step S102. For example, the notification control unit 36 ​​causes the first icon G1 on the display screen 8a to flash for a predetermined time (e.g., 5 seconds) and causes the sound output unit 9 to generate a sound. The electronic device 10 repeatedly performs the processes of steps S102 to S112 described above while the vehicle is traveling.

[0060] <Effects of this embodiment> The electronic device 10 of the above-described embodiment acquires a first set speed set based on the speed limit of the road on which the vehicle is located and a second set speed set by the user of the vehicle. Then, when the vehicle speed exceeds the first set speed, the electronic device 10 causes the notification unit 7 to perform a first notification, and when the vehicle speed exceeds the second set speed, the electronic device 10 causes the notification unit 7 to perform a second notification that is distinguishable from the first notification. As described above, by performing the first or second notification based on the second set speed in addition to the first set speed, it is possible to not only notify when the vehicle speed exceeds the road speed limit, but also to provide a notification at a timing that reflects the driver's intention and the vehicle's condition. This allows the user to be alerted at an appropriate timing, thereby improving the safety of the vehicle while it is traveling.

[0061] Although the present invention has been described above using the embodiments, the technical scope of the present invention is not limited to the scope described in the above embodiments, and various modifications and changes are possible within the scope of the gist of the present invention. For example, all or part of the device can be configured by distributing or integrating functionally or physically in any unit. In addition, new embodiments resulting from any combination of multiple embodiments are also included in the embodiments of the present invention. The effect of the new embodiment resulting from the combination combines the effect of the original embodiment. [Explanation of symbols]
