Description

Technical Field

[0001] The present invention relates to a blind spot assist device for visually recognizing blind spots of a saddle-type vehicle.

Background Art

[0002] Conventionally, for example, an out-of-vehicle visual recognition device described in Patent Document 1 is known. This out-of-vehicle visual recognition device includes optical means for projecting at least a part of the out-of-vehicle blind spot by direct visual observation from the driver's seat by reflection or refraction, traveling state detection means for detecting the vehicle speed or the gear stage of the transmission, and when it is detected based on the traveling state detection means that the vehicle is traveling at a specified speed or higher, or that the transmission is at a predetermined gear stage or higher, display blocking means for blocking the optical means or switching the direction or position so that an image other than the out-of-vehicle scene is projected, and the optical means is provided on a rearview mirror provided at the upper part of the windshield.

[0003] Also, for example, a driving support display device described in Patent Document 2 is known. This driving support display device is a driving support display device provided in the vehicle interior for controlling a display unit whose display surface shape can be changed, and includes a direction detection unit for detecting the direction of light incident on the display surface, a determination unit for determining whether the direction of the light detected by the direction detection unit is a specific direction in which the light is reflected by the display surface and directed toward the driver's eyes, and a shape control unit for controlling the shape of the display surface. On the condition that the determination unit determines that the direction of the light detected by the direction detection unit is the specific direction, the shape control unit changes the shape of the display surface so that a portion of the display surface that reflects the light toward the eyes decreases, and the display unit displays an image of a camera disposed on the vehicle.

Patent Document 1

[0005] However, in the external visibility device described in Patent Document 1, an optical means that displays at least a portion of the external blind spot is provided on a rearview mirror mounted on the top of the windshield. However, when the optical means is provided on the rearview mirror, there is a problem that the forward view may be restricted by the optical means.

[0006] Furthermore, the driver assistance display device described in Patent Document 2 had the problem that it incurred costs for the camera and the display unit for high visibility, as it displayed images from a camera installed in the vehicle on the display unit.

[0007] Therefore, the present invention has been made in view of the above problems, and aims to provide a blind spot assist device for a saddle-type vehicle that allows for the inexpensive confirmation of blind spots without restricting forward visibility when driving a saddle-type vehicle. [Means for solving the problem]

[0008] The present invention relates to a saddle-type vehicle C equipped with a blind spot assist device 1 for a saddle-type vehicle C, comprising a vehicle body frame 2, a steering mechanism 3 provided at the front end of the vehicle body frame 2 so as to be steerable left and right relative to the vehicle body frame 2, wherein the steering mechanism 3 comprises a steering shaft 5 extending substantially horizontally along the vehicle width direction, a pair of left and right handles 6a, 6b provided at both left and right ends of the steering shaft 5, and side mirrors 7a, 7b provided on the pair of left and right handles 6a, 6b, and is characterized in that it is provided on the steering mechanism 3 and has mirror portions 9a, 9b that reflect the lateral blind spot ranges RR1, LR1 which are outside the range of the lateral field of view seen by the occupant D of the saddle-type vehicle C via the side mirrors 7a, 7b. [Effects of the Invention]

[0009] According to the present invention, a passenger in a saddle-type vehicle can check blind spots inexpensively and reliably without restricting their forward view. [Brief explanation of the drawing]

[Modes for carrying out the invention]

[0011] (First embodiment of the present invention) The blind spot assist device for a saddle-type vehicle according to this embodiment will be described with reference to Figures 1 to 5. Figure 1 is an external view of the blind spot assist device according to this embodiment when mounted on a saddle-type vehicle, and Figure 2 is a diagram illustrating the blind spots of the saddle-type vehicle. Figure 1(A) is a left side view of the saddle-type vehicle, Figure 1(B) is a rear view of the saddle-type vehicle, and Figure 2 is a top view of the saddle-type vehicle.

[0012] In Figure 1, the saddle-type vehicle C comprises a vehicle frame 2 and a steering mechanism 3 provided at the front end of the vehicle frame 2 so as to be steerable left and right relative to the vehicle frame 2. The steering mechanism 3 comprises a pair of left and right front forks 4a, 4b supported so as to be steerable left and right, a steering shaft 5 connected to the front forks 4a, 4b and extending substantially horizontally along the width direction of the saddle-type vehicle C, a pair of left and right handles 6a, 6b provided at both ends of the steering shaft 5, a pair of left and right side mirrors 7a, 7b provided on the handles 6a, 6b, a meter unit 8 installed in the central part on the front side of the steering shaft 5 and displaying information related to the saddle-type vehicle C, and a pair of left and right mirrors 9a, 9b made of convex mirrors provided around the meter unit 8. In the example shown in Figure 1, the mirrors 9a, 9b are arranged on both the left and right sides of the meter unit 8, and the blind spot assist device 1 is realized by combining these configurations.

[0013] As shown in Figures 1 and 2, the driver D (passenger) of the saddle-type vehicle C covers the front area FR with the driver D's own forward field of view, the left rear area LR with the left side view (lateral field of view) via the left side mirror 7a, and the right rear area RR with the right side view (lateral field of view) via the right side mirror 7b. At this time, to the left of the driver D's left rear area LR, there is a left blind spot area LR1 (indicated by diagonal lines) (lateral blind spot range) that is outside the range of the left side view via the side mirror 7a, and to the right of the driver D's right rear area RR, there is a right blind spot area RR1 (indicated by diagonal lines) (lateral blind spot range) that is outside the range of the right side view via the side mirror 7b. The mirror part 9a of the blind spot assist device 1 shown in Figure 1 reflects the left blind spot area LR1, and the mirror part 9b reflects the right blind spot area RR1. Driver D can see the left blind spot area LR1 and the right blind spot area RR1 through the mirrors 9a and 9b.

[0014] Furthermore, the blind spot assist device 1 is not limited to a configuration in which the instrument section 8 and mirror sections 9a and 9b are integrated, but may have at least mirror sections 9a and 9b. In addition, although not shown in the external view of Figure 1, the steering mechanism 3 of the saddle-type vehicle C may be configured to include a front cowl (not shown) that covers the front forks 4a and 4b from the front and sides, thereby providing a windbreak function for the vehicle body.

[0015] The configuration of the blind spot assist device 1 will be described in detail below. Figure 3 is a diagram showing the configuration of the blind spot assist device 1 of the saddle-type vehicle C according to this embodiment. Figure 3(A) is a front view of the blind spot assist device 1, Figure 3(B) is a cross-sectional view taken from arrow A in Figure 3(A), and Figure 3(C) is an enlarged view of a part of Figure 3(B) (dashed line portion).

[0016] As shown in FIG. 3, the blind spot assisting device 1 includes an instrument section 8, which is a so-called meter that displays information related to the straddle-type vehicle C, and mirror sections 9a and 9b that are installed on both left and right sides of the instrument section 8 and are composed of convex mirrors formed in a convex shape in the outer direction. As shown in FIG. 3(C), each of the mirror sections 9a and 9b is, for example, made of a molded product of a transparent acrylic resin, and includes a transparent member 11 with a convex surface side, a metal film 12 of aluminum foil vapor-deposited on the back surface side (concave side) of the transparent member 11, for example, and a holding member 13 that is an AES resin molded product and holds the transparent member 11 with the metal film 12 vapor-deposited on the back surface side by insert molding.

[0017] As shown in FIG. 3(B), the instrument section 8 includes a display element 14 that is, for example, a TFT (Thin Film Transistor) type liquid crystal display, and a control section 15 that controls an image displayed on the display element 14. The display element 14 and the control section 15 are disposed in a state of being supported from below by a lower case 16, and are covered by an upper case 17 from above.

[0018] The upper case 17 is formed of, for example, AES resin, and a rectangular transparent acrylic resin plate 18 is held by insert molding in a region corresponding to the location where the display element 14 is disposed. That is, the driver D can visually recognize the content of the display element 14 through the transparent acrylic resin plate 18. The lower case 16 is formed of, for example, AES resin, is adhesively fixed to the upper case 17, and houses the display element 14 and the control section 15. Fixing portions 16a and 16b for fixing the mirror sections 9a and 9b are respectively formed to extend on the left and right side walls of the lower case 16, and the holding members 13 of the mirror sections 9a and 9b are fixed by screws 19a and 19b.

[0019] The control unit 15 consists of a microcomputer having a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), etc., mounted on a wiring board. The control unit 15 acquires various information regarding the straddle-type vehicle C (for example, signals from the wiper switch, signals indicating driving states such as driving speed and driving distance, vehicle information such as engine speed, remaining fuel, engine water temperature, and gear position, etc.) from the vehicle ECU (Electronic Control Unit) of the straddle-type vehicle C, and causes the acquired information, etc. to be displayed on the display element 14.

[0020] By having such mirror portions 9a, 9b, it becomes possible to visually recognize the blind spot areas (LR1, RR1) without restricting the driver D's forward field of view.

[0021] Also, in the configuration shown in FIG. 3, the steering mechanism 3 may have an angle adjustment mechanism capable of variably adjusting the angle with respect to the lower case 16 (outer cover) of the mirror portions 9a, 9b. FIG. 4 is a diagram showing the configuration in the blind spot assist device 1 of the straddle-type vehicle C according to the present embodiment when having an angle adjustment mechanism for adjusting the angles of the mirror portions 9a, 9b. In FIG. 4, similar to that shown in FIG. 3(B), fixing portions 16a, 16b extending in the left-right direction are formed from the left and right side walls of the lower case 16, and spherical bodies 161a, 161b are formed at the respective tip ends of these fixing portions 16a, 16b. Further, at the bottom of the holding members 13 of the mirror portions 9a, 9b, covering bodies 131a, 131b having a structure with a gap that encloses and covers the spherical bodies 161a, 161b and allows the mirror portions 9a, 9b to be freely movable and the fixed angle to be arbitrarily adjusted are formed. The driver D adjusts the angles of the mirror portions 9a, 9b to an angle that is easy to see the driver's own blind spot in a state where the covering bodies 131a, 131b enclose the spherical bodies 161a, 161b, and in that state, tightens the screws 19a, 19b to fix the angles of the mirror portions 9a, 9b.

[0022] Although Figures 3 and 4 illustrate a structure in which both mirror sections 9a and 9b are fixed to the lower case 16, the left and right side walls of the upper case 17 may be formed higher, and fixing sections 16a and 16b may be extended from these side walls to fix the mirror sections 9a and 9b.

[0023] In addition to the structures shown in Figures 3 and 4, the instrument section 8 and the mirror sections 9a and 9b may be formed integrally, for example. Figure 5 shows the structure of the blind spot assist device 1 for the saddle-type vehicle C according to this embodiment, when the instrument section 8 and the mirror sections 9a and 9b are formed integrally. As shown in Figure 5, the display elements 14 and control unit 15 constituting the instrument section 8 are housed in a state where they are covered from above by the upper case 17 and supported from below by the lower case 16, while the holding members 13 for the mirror sections 9a and 9b house them as side walls on the left and right sides. In other words, by making the holding members 13 for the mirror sections 9a and 9b function as part of the outer case that houses the instrument section 8, the number of parts can be reduced and the device configuration can be simplified, while protecting the instrument section 8 and improving the visibility of the blind spot for the driver D.

[0024] In Figure 3(A), the vertical width X1 of the mirror sections 9a and 9b and the vertical width X2 of the instrument section 8 are of different lengths. However, in each configuration shown in Figures 3 to 5, the instrument section 8 has a roughly rectangular shape when viewed from the front, and it is desirable that the vertical width X1 of the mirror sections 9a and 9b is formed to be roughly the same as the vertical width X2 of the instrument section 8 (see, for example, the structure in Figure 7 described later). Furthermore, as shown in Figures 3 to 5, in the side view of each configuration, it is desirable that the front end position Y1 of the mirror sections 9a and 9b (the position of the front surface in the line of sight from the driver D) and the front end position Y2 of the instrument section 8 (the position of the surface of the transparent acrylic resin plate 18) are formed flush with each other so as to be roughly the same. Moreover, in each configuration shown in Figures 3 to 5, it is desirable that the mirror sections 9a and 9b and the instrument section 8 both have the same color scheme and a metallic color. Specifically, for example, the upper case 17 is often black due to the characteristics of the material and the manufacturing process, but by applying a metallic-colored resin containing metal powder to the surface of the upper case 17, or by applying a plating or vapor deposition treatment to the surface, a plated appearance can be achieved, improving the sense of unity with the mirror surfaces of the mirror parts 9a and 9b. By using such a configuration, the sense of unity between the instrument section 8 and the mirror parts 9a and 9b can be strengthened, and the design can be improved.

[0025] Furthermore, in the configuration of the blind spot assist device 1 described above, mirrors 9a and 9b are provided on both the left and right sides of the instrument panel 8. However, other configurations are also possible, such as providing the mirrors 9a and 9b on the handlebars 6a and 6b, the vehicle frame 2, or, if a front cowl is provided, on the front cowl.

[0026] Furthermore, in addition to the type of saddle-type vehicle C in which the steering shaft 5 is exposed as shown in Figure 1, the blind spot assist device 1 according to this embodiment can also be applied to other types of saddle-type vehicles C in which the steering shaft 5 is covered by an exterior cover. That is, the exterior cover, such as the upper case 17 or lower case 16 described above, may be installed so as to cover the steering shaft 5, the instrument unit 8 may be placed on the steering shaft 5 side of the rear end of the exterior cover (i.e., on the inside of the exterior cover at the driver D side end of the exterior cover), and mirror units 9a and 9b may be provided around the instrument unit 8 (for example, between the instrument unit 8 and the steering wheel 6a and 6b).

[0027] Furthermore, the mirror sections 9a and 9b may be plane mirrors in addition to convex mirrors.

[0028] As described above, the blind spot assist device for the saddle-type vehicle C according to this embodiment comprises a vehicle frame 2 and a steering mechanism 3 provided at the front end of the vehicle frame 2 so as to be steerable left and right relative to the vehicle frame 2, the steering mechanism 3 comprises a steering shaft 4 extending substantially horizontally along the vehicle width direction, a pair of left and right handles 6a, 6b provided at both the left and right ends of the steering shaft 5, and side mirrors 7a, 7b provided on the pair of left and right handles 6a, 6b, and the blind spot assist device 1 for the saddle-type vehicle C is provided on the steering mechanism 3 and has mirrors 9a, 9b that reflect the right blind spot area RR1 and the left blind spot area LR1 which are outside the range of the lateral field of view seen by the driver D of the saddle-type vehicle C via the side mirrors 7a, 7b, so that the blind spot can be reliably assisted at low cost using mirrors without restricting the driver D's forward field of view and without the need for electronic devices.

[0029] Furthermore, if necessary, the steering mechanism 3 may further include a front cowl that covers the front and side of the front fork 4a, which is supported to be steerable left and right, and the steering shaft 5 is connected to the front forks 4a and 4b, and the mirrors 9a and 9b are provided on the handlebars 6a and 6b, the front cowl, or the vehicle frame 2. Thus, as described above, blind spots can be reliably mitigated without restricting the driver D's forward field of vision.

[0030] Furthermore, if necessary, the steering mechanism 3 may further include an outer cover that substantially covers the steering shaft 5 and an instrument section 8 disposed on the steering shaft 5 side of the rear end of the outer cover, and the mirror sections 9a and 9b are provided around the instrument section 8, so that, as described above, blind spots can be reliably mitigated without restricting the driver D's forward field of vision.

[0031] Furthermore, if necessary, the mirror sections 9a and 9b are positioned one on each side of the instrument section 8, so that blind spots on both the left and right sides can be covered with an inexpensive configuration.

[0032] Furthermore, since the mirror sections 9a and 9b are integrally constructed with the instrument section 8, dedicated parts for attaching the mirror sections 9a and 9b to the instrument section 8 are not required, thus preventing an increase in the number of parts.

[0033] Furthermore, if necessary, the instrument section 8 has a roughly rectangular shape when viewed from the front, and the vertical width of the mirror sections 9a and 9b is roughly the same as the vertical width of the instrument section 8. This improves the sense of unity between the instrument section 8 and the mirror sections 9a and 9b in appearance, and reduces the impression that the instrument section 8 and the mirror sections 9a and 9b are separate components.

[0034] Furthermore, if necessary, the front end positions of the mirror sections 9a and 9b and the front end position of the instrument section 8 are approximately coincident in a side view. As described above, this improves the sense of unity between the instrument section 8 and the mirror sections 9a and 9b in appearance, and reduces the impression that the instrument section 8 and the mirror sections 9a and 9b are separate components.

[0035] Furthermore, if necessary, the mirror sections 9a and 9b and the instrument section 8 can both have the same color scheme and a metallic finish, thereby improving the sense of color unity between the mirror sections 9a and 9b and the instrument section 8, and reducing the impression that the instrument section 8 and the mirror sections 9a and 9b are separate components.

[0036] Furthermore, if necessary, the steering mechanism 3 has an angle adjustment mechanism that allows for variable adjustment of the angle of the mirrors 9a and 9b relative to the outer cover, so that the angle of the mirrors 9a and 9b can be adjusted to an appropriate angle to cover blind spots according to the physique of the driver D.

[0037] Furthermore, since the mirror sections 9a and 9b are convex mirrors, they can cover a wide range of blind spots even in a compact size, as needed.

[0038] (Second embodiment of the present invention) The blind spot assist device for the saddle-type vehicle according to this embodiment will be explained with reference to Figures 6 and 7. The blind spot assist device 1 according to this embodiment alerts the driver D to check the mirror section 9a or mirror section 9b that reflects the blind spot when the driver D operates the turn signal.

[0039] Figure 6 is a functional block diagram showing the electrical configuration of the blind spot assist device 1 of the saddle-type vehicle C according to this embodiment. In Figure 6, the blind spot assist device 1 has a control unit 15 that, when the driver D operates the turn signal, acquires a signal from the vehicle ECU for the turn signal switch, controls the content displayed on the display element 14 according to the signal from the turn signal switch, and controls the illumination of the right lamp unit 21 or the left lamp unit 22, which are located on the front side of the steering axis 5, according to the signal from the turn signal switch.

[0040] The following describes an example of a series of driving operations performed by driver D, including the specific control details by the control unit 15. Figure 7 shows an example of the control details of the control unit 15 in the blind spot assist device 1 according to this embodiment. For example, suppose driver D operates the right turn signal when making a right turn. The control unit 15 obtains the ON signal for the right turn signal switch from the vehicle ECU. Then, as shown in Figure 7(A), the control unit 15 displays a message on the display element 14 of the instrument unit 8 prompting the driver to check the mirror unit 9b, which has the function of displaying the right blind spot area RR1, and also illuminates the right lamp unit 21. Driver D checks the right blind spot area RR1 with the mirror unit 9 in accordance with the message prompting the driver to check the mirror unit 9b displayed on the instrument unit 8, and if it is recognized that it is safe, performs a driving operation such as making a right turn or changing lanes to the right lane.

[0041] The same procedure applies when turning left; driver D activates the left turn signal when turning left. The control unit 15 receives the ON signal for the left turn signal switch from the vehicle ECU. As shown in Figure 7(B), the control unit 15 displays a message on the display element 14 of the instrument unit 8 prompting the driver to check the mirror unit 9a, which has the function of displaying the left blind spot area LR1, and also illuminates the left lamp unit 22. Driver D checks the left blind spot area LR1 with the mirror unit 9a according to the message displayed on the instrument unit 8 prompting the driver to check the mirror unit 9a, and if it is deemed safe, performs a driving operation such as turning left or changing lanes to the left lane.

[0042] Furthermore, the display prompting the user to check the mirror sections 9a and 9b by the control unit 15 may be displayed not only on the display element 14 of the instrument section 8, but also on an indicator provided on, for example, the upper case 17.

[0043] Furthermore, the mirror 9a may be configured to capture at least a portion of the steering wheel 6a when capturing the left blind spot area LR1, and the mirror 9b may be configured to capture at least a portion of the steering wheel 6b when capturing the right blind spot area RR1. By arranging the mirrors 9a and 9b in this manner, the driver D can more easily recognize which position and which direction each mirror 9a and 9b is viewing.

[0044] As described above, the blind spot assist device 1 of the saddle-type vehicle C according to this embodiment has a control unit 15 that controls the right lamp unit 21 and the left lamp unit 22 which are arranged on the front side of the steering axis 5. The control unit 15 performs a display process in the instrument unit 8 that prompts the driver to check the mirror units 9a and 9b. For example, when the driver D operates the turn signal, a warning can be issued that the driver should check the blind spot, thereby improving safety. [Explanation of Symbols]
