[0003] [Patent Document 1] Japanese Patent Application Publication No. 7-32913 [Patent Document 2] Patent No. 6717009 Summary of the Invention [Problem to be solved by the invention]
[0004] However, since vehicle mirrors are originally intended to allow the driver to see areas that the driver cannot see, if vehicle information is constantly displayed on the mirror, as described in Patent Document 1, this can easily become annoyance to the driver as excessive notifications. On the other hand, in order to notify the driver of vehicle information as needed, it is possible to move the display to make the driver aware of it, as described in Patent Document 2. However, the technology of moving the display itself is difficult to apply to vehicles such as motorcycles, where the location where the display can be moved is limited. The present invention has been made in consideration of the above-mentioned circumstances, and has an object to provide a vehicle that can reduce annoyance and appropriately notify a driver of vehicle surrounding information. [Means for solving the problem]
[0005] This specification contains the entire contents of Japanese patent application No. 2021-107013, filed on June 28, 2021. The vehicle is equipped with a vehicle surroundings detection sensor that detects the vehicle's surrounding environment, a speed sensor that detects the vehicle's speed, and a plurality of vehicle surroundings information display areas that display the vehicle surroundings information detected by the vehicle surroundings detection sensor, and is characterized in that the vehicle surroundings information display area to be displayed is changed depending on the speed detected by the speed sensor.

That is, for example, a left light source (not shown) and a right light source (not shown) are provided, and a BSI image simulating the host vehicle 1 and another vehicle 200 approaching and entering the blind spot AL on the left side of the host vehicle 1 can be displayed by the left light source being illuminated, and a BSI image simulating the host vehicle 1 and another vehicle 200 approaching and entering the blind spot AR on the right side of the host vehicle 1 can be displayed by the right light source being illuminated.
[0030] The meter indicator 51 and the mirror indicator 52 are adjacent to the display device 30 and the rearview mirrors 26L, 26R, so that they can be visually and functionally integrated, and the lighting positions of the indicators 53 to 56 can be easily changed as if they were continuous. This makes it easier for the driver to notice notifications from the indicators 53 to 56, and improves the design.
[0031] In particular, in this embodiment, on both the left and right sides, the distance in the vehicle width direction from indicator 54 at the meter end to indicator 55 at the mirror support part is smaller than the distance from indicator 53 at the center of the meter to indicator 54 at the meter end. Also, on both the left and right sides, the distance in the vehicle width direction from indicator 55 at the meter end to indicator 56 at the mirror support part is smaller than the distance from indicator 53 at the center of the meter to indicator 54 at the meter end.
[0032] In FIG. 3, it is known that the range that the driver R1 can see without moving his / her eyes, that is, the visual field θ0 to θ4, becomes narrower as the speed of the host vehicle 1 increases. In general, when the speed of the host vehicle 1 is 0 km / h, the driver R1 has a visual field θ0 of 200° in total in the left-right direction with respect to the front of the vehicle (front center line C in the vehicle width direction). In addition, when the speed of the host vehicle 1 is 40 km / h, the driver R1 is assumed to have a visual field θ1 of a total range of 100° in the left and right directions with respect to the front of the vehicle.
[0033] Furthermore, when the speed of the host vehicle 1 is 70 km / h, the driver R1 is assumed to have a visual field θ2 of 75° in total in the left-right direction with respect to the front of the vehicle. In addition, when the speed of the host vehicle 1 is 100 km / h, the driver R1 is assumed to have a visual field θ3 of 40° in total in the left and right directions with respect to the front of the vehicle. Furthermore, when the speed of the host vehicle 1 is 130 km / h, the driver R1 is assumed to have a visual field θ4 of 30° in total in the left and right directions with respect to the front of the vehicle.
[0034] In this embodiment, the indicators 56L, 56R of the mirror are provided inside the field of view θ2 and outside the field of view θ3. The indicators 55L, 55R of the mirror support are provided inside the mirror indicators 56L, 56R in the vehicle width direction and at a position corresponding to the outer end of the field of view θ3. The indicators 54L, 54R of the meter end are provided inside the mirror indicators 55L, 55R in the vehicle width direction and at a position corresponding to the outer end of the field of view θ3. The indicator 53 of the meter center is provided in the center of the display device 30 in the vehicle width direction, and is therefore provided inside the meter end indicators 54L, 54R in the vehicle width direction and inside the fields of view θ0 to θ4.

[0054] The obstacle detection determination means 111 determines, based on information input from the vehicle front monitoring sensor 130 and the vehicle surroundings detection sensor 140, whether or not an obstacle has been detected in front of or around the vehicle. The obstacle detection judgment means 111 of this embodiment judges whether or not another vehicle 200 that may be an obstacle has been detected in front of the vehicle based on monitoring information from the forward monitoring radar 131, forward monitoring laser 132, and forward monitoring camera 133 of the vehicle forward monitoring sensor 130. In addition, the obstacle detection judgment means 111 judges whether or not another vehicle 200 that may be an obstacle has been detected around the vehicle based on detection information from the periphery detection radar 141, periphery detection laser 142, and periphery detection camera 143 of the vehicle periphery detection sensor 140.
[0055] In particular, the obstacle detection determination means 111 of this embodiment, when determining whether or not another vehicle 200 has been detected around the vehicle, determines whether or not another vehicle 200 approaching or entering the blind spots AL, AR of the vehicle 1 has been detected. For example, the obstacle detection determination means 111 can determine that the other vehicle 200 has been detected in the left blind spot AL when it is detected that the direction and distance from the vehicle 1 to the other vehicle 200 are located in a certain area on the left rear side of the vehicle 1 that is set in advance taking into account a margin. Also, the obstacle detection determination means 111 can determine that the other vehicle 200 has been detected in the right blind spot AR when it is detected that the direction and distance from the vehicle 1 to the other vehicle 200 are located in a certain area on the right rear side of the vehicle 1 taking into account a margin.
[0056] The display area changing means 112 changes the indicators 53-56 that display the vehicle surroundings information according to the vehicle speed. When the vehicle is traveling at a low speed, the display area changing means 112 changes the indicators to be controlled to the indicators 54-56 located on the outer side in the vehicle width direction among the multiple indicators 53-56. When the vehicle is traveling at a high speed, the display area changing means 112 changes the indicators to be controlled to the indicators 53-55 located on the inner side in the vehicle width direction among the multiple indicators 53-56.
[0057] In this embodiment, the display area change means 112 presets a number of speed thresholds based on the fields of view θ0 to θ4, and each time the vehicle speed exceeds a larger threshold, the indicator 53 to 56 to be controlled is changed to an indicator 53 to 56 that is more inward in the vehicle width direction. In detail, the display area changing means 112 acquires the vehicle speed from the vehicle speed sensor 152. Then, when the vehicle speed is less than 40 km / h (first threshold), the display area changing means 112 changes the control target to the mirror indicators 56L, 56R. Also, when the vehicle speed is 40 km / h (first threshold speed) or more and less than 70 km / h (second threshold), the display area changing means 112 changes the control target to the mirror stay indicators 55L, 55R. Furthermore, when the vehicle speed is 70 (second threshold speed) km / h or more and less than 100 km / h (third threshold), the display area changing means 112 changes the control target to the indicators 54L, 54R at the meter end. Also, when the vehicle speed is 100 km / h (fourth threshold) or more, the display area changing means 112 changes the control target to the indicator 53 at the center of the meter.
[0058] The indicator control means 113 controls the BSI display device 50 based on the determination result of the obstacle detection determination means 111. In this embodiment, when another vehicle 200 is detected in the blind spots AL, AR, the indicator control means 113 controls the indicators 53 to 56 set (changed) by the display area change means 112 as control targets.
[0059] When another vehicle 200 is detected in the left blind spot AL, the indicator control means 113 turns on the indicators 53, 54L, 55L, and 56L corresponding to the left side, which are the indicators 53 to 56L set by the display area changing means 112. When another vehicle 200 is detected in the right blind spot AR, the indicator control means 113 turns on the indicators 53, 54R, 55R, and 56R corresponding to the right side, which are the indicators 53 to 56R set by the display area changing means 112. When another vehicle 200 is no longer detected in the blind spots AL and AR, the indicator control means 113 turns off the indicators 53 to 56.
[0060] FIG. 5 is a flowchart showing the operation of the indicator display process of the ECU 100. In the present embodiment, the indicator display process is started, for example, when a driving assistance operation is inputted through the operation unit 35, and is repeated periodically at an appropriate timing.
[0061] The ECU 100 determines whether or not an object is present in the blind spots AL and AR, that is, whether or not another vehicle 200 has been detected in the blind spots AL and AR (step S1). When there is no object in the blind spots AL and AR (step S1 / NO), the ECU 100 ends the indicator display process with the indicators 53 to 56 turned off.
[0062] When an object is present in the blind spots AL and AR (step S1 / YES), the ECU 100 acquires the vehicle speed from the vehicle speed sensor 152 (step S2). When the ECU 100 acquires the vehicle speed from the vehicle speed sensor 152, the ECU 100 determines whether the vehicle speed is 40 km / h or higher (step S3). If the vehicle speed is not 40 km / h or more (step S3 / NO), the ECU 100 lights up the indicator 56 of the mirror for indication (step S9).
[0063] If the vehicle speed is 40 km / h or more (step S3 / YES), the ECU 100 determines whether the vehicle speed is 70 km / h or more (step S4). If the vehicle speed is not 70 km / h or more (step S4 / NO), the ECU 100 lights up the indicator 55 of the mirror support portion to provide an indication (step S8).
[0064] If the vehicle speed is 70 km / h or more (step S4 / YES), the ECU 100 judges whether the vehicle speed is 100 km / h or more (step S5). If the vehicle speed is not 100 km / h or more (step S5 / NO), the ECU 100 lights up the indicator 54 at the end of the meter to display it (step S7).
[0065] If the vehicle speed is 100 km / h or more (step S5 / YES), the ECU 100 lights up the indicator 53 in the center of the meter (step S6). After displaying the indicators 53 to 56, the ECU 100 ends the indicator display process.
[0066] In this embodiment, when the vehicle (motorcycle) 1 is traveling and another vehicle 200 approaching or entering the blind spots AL, AR is detected by the vehicle surroundings detection sensor 140 or the like, the BSI display device 50 is turned on and a BSI image is displayed. This makes it easier for the driver R1 to notice the other vehicle 200 approaching or entering the blind spots AL, AR.
[0067] At this time, in this embodiment, the control target, i.e., the lighting position, of the indicators 53-56 of the BSI display device 50 is changed according to the vehicle speed. Therefore, compared to a case where the lighting position of the BSI display device 50 is not changed, the notification of the BSI is less likely to be excessive information compared to the original display information of the display device 30 and the rearview mirror 26. Also, compared to a case where the BSI image continues to be displayed on the rearview mirror 26, which is the outer end in the vehicle width direction, the lighting position is switched according to the field of view θ0-θ4, which narrows depending on the vehicle speed, and it is possible to properly notify the driver without moving the indicators 53-56 themselves.
[0068] As described above, according to this embodiment of the present invention, the vehicle 1 includes a vehicle surroundings detection sensor 140 that detects the surrounding environment of the vehicle 1, a vehicle speed sensor 152 that detects the vehicle speed, and a plurality of indicators 53, 54, 55, 56 that display vehicle surroundings information detected by the vehicle surroundings detection sensor 140. In the vehicle 1, the indicators 53, 54, 55, 56 to be displayed as control targets are changed according to the vehicle speed detected by the vehicle speed sensor 152. Therefore, the indicators 53, 54, 55, 56 are changed according to the size of the visual fields θ0 to θ4 that change according to the magnitude of the vehicle speed, so that appropriate notification according to the state of the driver R1 can be given. This reduces annoyance and allows appropriate notification of vehicle surroundings information.
[0069] In this embodiment, when the vehicle is traveling at a low speed, the vehicle surroundings information is displayed by the indicators 53, 54, 55, 56 located on the outer side in the vehicle width direction among the multiple indicators 53, 54, 55, 56, and when the vehicle is traveling at a high speed, the vehicle surroundings information is displayed by the indicators 53, 54, 55, 56 located on the inner side in the vehicle width direction among the multiple indicators 53, 54, 55, 56. Therefore, the vehicle surroundings information can be appropriately notified to the driver R1 by displaying the vehicle surroundings information by the indicators 53, 54, 55, 56 that are closer to the center line C in the vehicle width direction in accordance with the fact that the field of view θ0 to θ4 of the driver R1 narrows toward the center as the vehicle speed increases.
[0070] Moreover, this embodiment further includes a display device 30 that displays at least information related to the state of the vehicle 1, and a rearview mirror 26 that includes a connection part 42 that connects the vehicle 1 to a mirror 41 that reflects the rear, and indicators 53, 54, 55, 56 are provided on at least one of the display device 30 or the rearview mirror 26. Therefore, by providing the indicators 53, 54, 55, 56 on the display device 30 and the rearview mirror 26, it is possible to efficiently notify the driver R1 of vehicle surroundings information by utilizing devices provided on the vehicle 1.
[0071] In this embodiment, a plurality of indicators 53, 54, 55, 56 are provided on at least one of the display device 30 and the rearview mirror 26. Therefore, by providing a plurality of indicators 53, 54, 55, 56 in one component, the display locations (control targets) of the indicators 53, 54, 55, 56 can be continuously changed in accordance with changes in the vehicle speed.
[0072] In this embodiment, a plurality of rear-view mirrors 26L, 26R are provided on the vehicle 1, and the display device 30 and the plurality of rear-view mirrors 26L, 26R are adjacent to each other. Therefore, since the display device 30 and the rear-view mirrors 26L, 26R are adjacent to each other, the indicators 53, 54, 55, 56 can be changed as if they were continuous, which makes it easier for the driver R1 to notice them and improves the design.
[0073] In this embodiment, the indicators 53, 54, 55, 56 are provided on at least one of the upper part of the display device 30 and the upper part of the rearview mirrors 26L, 26R. By placing the indicators 53, 54, 55, 56 above the respective components, the indicators 53, 54, 55, 56 can be disposed in positions where the driver can easily notice them.
[0074] In addition, in this embodiment, the indicators 53, 54, 55, 56 are provided at positions that are symmetrical with respect to the vehicle width centerline C of the vehicle 1. This provides a good balance in the left-right direction, and makes it easier to notify the driver R1 of vehicle surroundings information more effectively in a vehicle in which the driver is located on the vehicle width centerline C. Therefore, the BSI display device 50 of this embodiment is more suitable for a motorcycle 1 in which the display device 30 and the rearview mirrors 26L, 26R are closer to each other than for a four-wheeled vehicle.
[0075] [Other embodiments] The above-described embodiment merely shows one aspect of the present invention, and any modification and application can be made without departing from the spirit and scope of the present invention.
