[0002] Conventionally, technologies for detecting objects such as people and vehicles present on the side of a vehicle and performing alerts to a driver, vehicle control, etc. have been developed.

[0006] Problems to be Solved by the Invention

[0007] When a radar device is installed near a fuel tank as in the technology of Patent Document 1, sometimes the radar irradiation range of the radar device cannot be sufficiently ensured. That is, due to the adjustment and modification of vehicle side monitoring, it is necessary to monitor a larger range of the side than before. When a radar device is installed near a fuel tank as in the technology of Patent Document 1, sometimes it cannot cope with the adjustment.

[0008] That is, in a detection device for detecting an object present on the side of a vehicle, in order to monitor the side of the vehicle in a larger range, it is necessary to change the mounting position of the detection device.

[0009] However, due to the relationship between the layout of other components on the side of the vehicle, the mounting position of the detection device is sometimes restricted. Therefore, the conventional technology as disclosed in Patent Document 1 has room for improvement in ensuring the mountability of the detection device.

[0010] This application is created in view of the above problems, and one of its purposes is to ensure the mountability of a detection device in an installation structure of a detection device for detecting an object present on the side of a vehicle.

[0011] Means for Solving the Problems

[0012] This application is made to solve at least a part of the above problems and can be implemented as the following aspects or application examples.

[0013] (1) The mounting structure of the detection device in this application example includes: a mudguard, which is mounted on the vehicle body frame of the vehicle and is disposed behind the wheel of the vehicle. The mudguard has an outer surface portion that constitutes the wall surface on the outer side in the vehicle width direction and a rear surface portion that is continuously provided with the outer surface portion and constitutes the wall surface on the rear side in the vehicle length direction. An opening that communicates the outer side in the vehicle width direction with the inner side in the vehicle width direction is provided on the outer surface portion; a detection device that is provided to detect an object on the side of the vehicle and is disposed in the opening of the mudguard; and a bracket that is located in front of the rear surface portion and is disposed overlapping the outer surface portion when viewed from the outer side in the vehicle width direction. One end of the bracket is directly or indirectly mounted on the vehicle body frame, and the detection device is mounted at the other end. The detection device is cantilever-supported in a state of being disposed in the opening.

[0014] Thus, the bracket is located in front of the rear surface portion of the mudguard and is disposed overlapping the outer surface portion when viewed from the outer side in the vehicle width direction, and the detection device is cantilever-supported in a state of being disposed in the opening of the outer surface portion. That is, since the bracket is disposed inside the mudguard, the detection device can be mounted on the mudguard. Even with such a structure in which the bracket is disposed inside the mudguard, the detection device can irradiate the radar outward from the opening of the outer surface portion. Therefore, the detection device can be appropriately mounted on the mudguard. Thus, the mountability of the detection device can be ensured in the mounting structure of the detection device.

[0015] (2) Additionally, in the mounting structure of the detection device in this application example, it may further include: a rear surface side support member that is disposed behind the rear surface portion of the mudguard in the vehicle length direction and is fixed to the rear surface portion; and an auxiliary bracket that is mounted at one end in the vehicle length direction on the bracket and is mounted at the other end in the vehicle length direction on the rear surface side support member, and connects the bracket and the rear surface side support member.

[0016] Thus, the auxiliary bracket is interposed between the bracket and the rear surface portion of the mudguard along the vehicle length direction, so the bracket and the rear surface side support member are connected via the auxiliary bracket. Therefore, the auxiliary bracket supports the bracket in a manner that suppresses the influence of external forces along the vehicle length direction. Thus, the bracket is strengthened. As a result, vibration of the detection device can be suppressed.

[0017] (3) Additionally, in the mounting structure of the detection device in this application example, it may be that the bracket is disposed non-contact with respect to the opening in a state where the detection device is disposed in the opening. Thereby, friction between the bracket and the mudguard can be prevented. In addition, it is difficult to transmit vibration from the mudguard to the bracket, so vibration of the detection device can be suppressed.

[0018] (4) Further, in the mounting structure of the detection device of the present application example, it may be that the wiring of the detection device is disposed along the rear surface of the bracket in the vehicle length direction. In this case, the bracket can function as a protection member that prevents flying stones and the like from colliding with the wiring from the front during the vehicle's travel.

[0019] (5) Further, in the mounting structure of the detection device of the present application example, the mounting structure of the detection device may include: a rear surface side support member that is disposed behind the rear surface portion of the fender in the vehicle length direction and fixed to the rear surface portion; an upper surface side support member that is fixed to the upper surface portion of the wall surface that forms the upper side of the fender; and a front end side support member that is fixed to the front end portion of the fender in the vehicle length direction. The bracket is disposed in front of the rear surface side support member and behind the front end side support member in the vehicle length direction, and is disposed below the upper surface side support member.

[0020] Thus, the bracket is disposed in front of the rear surface side support member and behind the front end side support member in the vehicle length direction, and is disposed below the upper surface side support member. Therefore, the bracket can be disposed inside the fender without interfering with the support members that support the fender.

[0021] (6) Further, in the mounting structure of the detection device of the present application example, it may be that the upper surface side support member is disposed in front of the rear surface side support member and behind the front end side support member in the vehicle length direction, and the bracket is indirectly mounted on the vehicle body frame via the upper surface side support member.

[0022] Thus, the bracket can be disposed inside the fender without interfering with the support members that support the fender, and the bracket can be stably mounted on the vehicle body frame via the upper surface side support member.

[0033] [1. Structure]

[0034] Figure 1 It is a perspective view of the front part of the vehicle 2 when observing the installation structure of the detection device ( Figure 1 indicated by the dashed line in ) 1 from the left rear, with a part omitted. In addition, the installation structure of the detection device 1 is provided on the left and right of the vehicle 2, and the left and right have substantially the same (left-right symmetric) structure. Therefore, the left side will be described below, and the detailed description of the right side will be omitted.

[0035] The detection device 1 is a vehicle side monitor that detects objects such as people and other vehicles existing on the side of the vehicle 2. The detection signal of the detection device 1 is used for the BSA (Blind Spot Assist) device that generates an alarm for the driver when a person, other vehicle, etc. existing on the side of the vehicle 2 is detected. As an example of the detection device 1, for example, a millimeter wave radar that emits millimeter waves toward the irradiation range on the side of the vehicle 2 can be cited.

[0036] Figure 1The vehicle 2 is a truck including a vehicle body frame 10 and a cab (not shown) disposed above the front portion of the vehicle body frame 10 .

[0037] The vehicle body frame 10 has a ladder-type frame structure. Specifically, the vehicle body frame 10 has a pair of longitudinal beams 11 (only the left side is shown in the figure) extending in the vehicle length direction (front-rear direction) and separated from each other in the vehicle width direction (left-right direction) and a plurality of transverse beams (omitted in the figure), forming a ladder shape.

[0038] A cab bridge 12 for supporting the rear end of the cab from below is provided at the front portion of the vehicle body frame 10. The cab bridge 12 extends upward from each of the pair of longitudinal beams 11 and is fixed across the longitudinal beams 11, and has an inverted U-shape or an arch shape.

[0039] A fender 20 is provided on the outer side (outer side in the vehicle width direction) of the vehicle body frame 10 .

[0040] The fender 20 is a mud guard member disposed behind a front wheel (not shown) of the vehicle 2 .

[0041] The fender 20 is formed as a cover body that surrounds the outer side surface, the rear surface, and the upper surface. Specifically, the fender 20 includes an outer side surface 20A that constitutes a wall surface on the outer side in the vehicle width direction, a rear surface portion 20B that is continuous with the rear end of the outer side surface 20A and constitutes a wall surface on the rear side in the vehicle length direction, and an upper surface portion 20C that is continuous with the upper end of the outer side surface 20A and the rear surface portion 20B and constitutes a wall surface on the upper side. In this specification, the space side surrounded by the outer side surface 20A, the rear surface portion 20B, and the upper surface portion 20C is referred to as the "inner side of the fender 20".

[0042] The outer surface portion 20A is provided with an opening portion 24 extending through the vehicle width direction. The opening portion 24 is a window portion that connects the outer side with the inner side in the vehicle width direction, and is provided so that the cover 32 described later protrudes (is inserted) to the outside of the fender 20. That is, the outer surface portion 20A located at the front side of the rear surface portion 20B of the fender 20 is provided with the opening portion 24, and the detection device 1 is engaged with the opening portion 24. The size and shape of the opening portion 24 are set according to the appearance shape and size of the detection device 1.

[0043] Figure 2 Shown from Figure 1 The fender 20 is removed. Figure 1 as well as Figure 2 As shown, the fender 20 is fixed to the vehicle body frame 10 at three locations, namely, the rear surface portion 20B, the upper surface portion 20C, and the front end portion 20D (the front end portion of the upper surface portion 20C) of the fender 20 by means of a rear surface side support 21, an upper surface side support 22, and a front end side support 23.

[0044] Among the rear - surface - side support member 21, the upper - surface - side support member 22, and the front - end - side support member 23, the rear - surface - side support member 21 and the upper - surface - side support member 22 are fixed to an upper bracket 12A extending outward from the cab bridge 12 at a position above the fender 20 (above the longitudinal beam 11). The front - end - side support member 23 is fixed to the outer side surface of the longitudinal beam 11.

[0045] The rear - surface - side support member 21 is formed of an L - shaped pipe member and is disposed behind the fender 20. The rear - surface - side support member 21 is fixed to the upper bracket 12A at its upper end portion, extends downward along the rear - surface portion 20B from the upper bracket 12A, and bends outward at the lower end portion of the rear - surface portion 20B and extends outward in the vehicle width direction. The rear - surface - side support member 21 is fixed to the lower end portion of the rear - surface portion 20B by two support fittings 21A and 21B that are separated and arranged in the vehicle width direction.

[0046] In addition, as Figure 1 shown, the rear - surface portion 20B is also fixed to a rear - surface - side sub - support member 21C that protrudes outward from the lower end portion of the cab bridge 12.

[0047] The upper - surface - side support member 22 is disposed at a position in front of the rear - surface - side support member 21 and behind the front - end - side support member 23 in the vehicle length direction, and includes a first member 22A extending outward from the upper bracket 12A and a second member 22B extending forward (in the vehicle length direction) from the upper bracket 12A. The first member 22A of the upper - surface - side support member 22 is fixed to the upper - surface portion 20C of the fender 20 at two positions (multiple positions) separated along the vehicle width direction. The second member 22B of the upper - surface - side support member 22 extends over substantially the entire vehicle length of the upper - surface portion 20C in the vehicle length direction, contacts the upper - surface portion 20C, and is fixed to the upper - surface portion 20C at its front - end portion.

[0048] The front - end - side support member 23 extends outward and upward from the longitudinal beam 11 and supports the front - end portion of the upper - surface portion 20C (the upper surface of the front - end portion of the fender 20) from the lower - surface side.

[0049] The front - end - side support member 23 and the front - end portion of the upper - surface portion 20C are fixed at two positions (multiple positions) separated along the vehicle width direction.

[0050] As described above, the fender 20 is mounted on the outside of the vehicle body frame 10 by the rear - surface - side support member 21, the upper - surface - side support member 22, and the front - end - side support member 23.

[0051] In the mounting structure of the detection device 1 of this application example, a BSA bracket 30 for supporting the detection device 1 is arranged inside the fender 20 ("bracket", Figure 1 represented by a dashed line in the figure).

[0052] As Figure 1 shown, it is assumed that the BSA bracket 30 arranged inside the fender 20 ( Figure 1 represented by a dashed line in the figure) is located in front of the rear surface portion 20B of the fender 20 and is arranged to overlap with the outer side surface portion 20A of the fender 20 when viewed from the outside in the vehicle width direction. In other words, as Figure 2 shown, it is assumed that the BSA bracket 30 is arranged in front of the rear surface side support member 21 and behind the front end side support member 23. In addition, the BSA bracket 30 is arranged below the upper surface side support member 22 and above the lower end of the longitudinal beam 11.

[0053] As Figure 1 and Figure 2 shown, one end 30A of the BSA bracket 30 on the inner side in the vehicle width direction is fixed to the vehicle body frame 10 side, extends from the vehicle body frame 10 side (inner side in the vehicle width direction) to the outside and downward, and mounts the detection device 1 together with the outer cover 32 at the other end 30B.

[0054] That is, the BSA bracket 30 cantilever - supports the detection device 1 in a state where it is arranged (engaged) with the opening 24 as Figure 1 shown.

[0055] Figure 3 is a side view showing an enlarged view of the mounting structure of the detection device 1 of Figure 1 . In addition, Figure 4 is a rear view when observing the mounting structure of the detection device 1 from the rear in the vehicle length direction. In addition, in Figure 3 the fender 20 is represented by a dashed line. In addition, in Figure 4 a part of the fender 20 is represented by a single - dotted line, and a part of the mounting structure of the detection device 1 is omitted.

[0056] As Figure 3 and Figure 4 shown, the BSA bracket 30 is formed by bending a flat plate member having a face extending in both the vehicle width direction and the vertical direction. Specifically, when viewed along the vehicle width direction as Figure 3 shown, the BSA bracket 30 has an "L - shaped" configuration in which an inclined portion that is more rearward in the vehicle length direction as it goes downward is continuously provided with a portion extending in the vertical direction. In addition, when viewed as Figure 4When viewed in the longitudinal direction of the vehicle as shown, the BSA bracket 30 is formed in a "C shape" obtained by continuously arranging a portion extending in the vertical direction from one end 30A, a portion that is located more on the outer side in the vehicle width direction as it goes downward, and a portion extending in the vehicle width direction.

[0057] One end 30A of the BSA bracket 30 is fixed to the upper surface side support member 22 together with the upper surface portion 20C of the fender 20. Figure 5 It is an enlarged view of the fixing portion of the BSA bracket 30, the fender 20, and the upper surface side support member 22. As Figure 3 shown, in a state where the first member 22A of the upper surface side support member 22 is overlapped on the upper surface portion 20C of the fender 20, the support bracket 26 disposed on the upper surface of the first member 22A and one end 30A of the BSA bracket 30 disposed on the lower surface side of the upper surface portion 20C of the fender 20 are fastened and connected by screws. Thus, one end 30A of the BSA bracket 30, the upper surface side support member 22, and the upper surface portion 20C of the fender 20 are fixed (fastened together). Therefore, the BSA bracket 30 of the present embodiment is indirectly mounted on the vehicle body frame 10 via the upper surface side support member 22 and the upper surface portion 20C of the fender 20.

[0058] Figure 6 It is an enlarged perspective view when viewing the other end 30B of the BSA bracket 30 from the inside of the fender 20. In addition, in Figure 6 the fender 20 is omitted.

[0059] As Figure 6 shown, the other end 30B of the BSA bracket 30 is a face portion extending along the vehicle width direction and the vertical direction. For this other end 30B, a holding member 31 for holding the detection device 1, a cover 32 that covers the holding member 31 from the outside, and a protective cover 33 (represented by a dotted line in the figure) that covers the detection device 1 held by the holding member 31 from the inside are provided.

[0060] The holding member 31 is formed in an L shape when viewed from above, and includes a first face portion 31A that constitutes a fixing face with respect to the other end 30B and a second face portion 31B that constitutes a holding face for the detection device 1.

[0061] The first face portion 31A is a face portion extending along the vehicle width direction and the vertical direction, the same as the other end 30B. The second face portion 31B is connected to the outer end in the vehicle width direction of the first face portion 31A and extends forward from the first face portion 31A. A window portion 31C communicating from the inside to the outside in the vehicle width direction is provided in the second face portion 31B, and the detection device 1 is held in the window portion 31C.

[0062] The cover 32 is an outer cover member on the vehicle outside with a hat-shaped cross section. As Figure 1is arranged outside the vehicle width direction with respect to the detection device 1 as shown ( Figure 1 is represented by a dashed line in). The outer cover 32 is fixed to the outer surface of the holding member 31 and covers the detection device 1 from the outside.

[0063] The outer cover 32 is formed of a material through which millimeter waves emitted from the detection device 1 can pass and a plate thickness. In addition, the outer dimensions of the outer cover 32 are set to be smaller than the diameter of the opening 24 provided in the outer side surface 20A of the fender 20, and the outer cover 32 can protrude (be inserted) from the inside of the fender 20 to the outside through the opening 24.

[0064] The protective cover 33 is a cover member that protects the detection device 1 held by the holding member 31 from flying stones and the like during the running of the vehicle 2. For example, the protective cover 33 is provided so as to cover the four surfaces on the inner side, upper side, lower side, and front side in the vehicle width direction with respect to the surface of the holding member 31 facing the inner side in the vehicle width direction, and has a threaded hole (not shown in the figure) for being mounted on the other end 30B of the BSA bracket 30 together with the first surface 31A of the holding member 31.

[0065] When the holding member 31, the outer cover 32, and the protective cover 33 are mounted on the other end 30B of the BSA bracket 30, the outer cover 32 is fixed to the holding member 31 in a state where the detection device 1 is mounted on the holding member 31. Then, the holding member 31 and the outer cover 32 are assembled to the other end 30B of the BSA bracket 30 in a state where they are disposed in the opening 24. Then, the protective cover 33 is mounted inside the holding member 31, and the first surface 31A of the holding member 31 and the protective cover 33 are fixed (jointly fastened) to the other end 30B of the BSA bracket 30.

[0066] In a state where the holding member 31, the outer cover 32, and the protective cover 33 are mounted on the other end 30B of the BSA bracket 30, as Figure 4 shown, a gap 24X is provided between the opening 24 and the outer cover 32. That is, the outer dimensions of the outer cover 32 and the diameter of the opening 24 are set such that the outer cover 32 (a part of the BSA bracket 30) is separated from the opening 24 by the gap 24X. In other words, the BSA bracket 30 is provided non - contact with respect to the opening 24 in a state where the detection device 1 is disposed in the opening 24.

[0067] The gap 24X is set to an appropriate size that can prevent contact (interference) between the outer cover 32 (bracket 30 side) and the opening 24 (fender 20 side). From the viewpoints of ensuring the mud - guarding performance of the fender 20, the aerodynamic performance during running, and the beautiful appearance of the fender 20, it is preferably set to the minimum that can prevent contact (interference) without expanding the gap 24X.

[0068] In Figure 6In the example, the wiring 34 of the detection device 1 held by the holding member 31 is disposed along the rear surface in the vehicle length direction of the BSA bracket 30. The wiring 34 is connected to a control device (not shown) and transmits the detection signal of the detection device 1.

[0069] In this case, since the BSA bracket 30 is disposed on the front side with respect to the wiring 34, the BSA bracket 30 also functions as a protection member that prevents flying stones or the like from colliding with the wiring 34 from the front during the running of the vehicle 2.

[0070] In the BSA bracket 30 of this application example, in order to strengthen the BSA bracket 30 against external forces acting in the longitudinal direction (front - rear direction) of the BSA bracket 30, as Figure 3 shown, ribs 35 are formed, and an auxiliary bracket 40 as shown in Figure 2 and Figure 3 is provided.

[0071] The auxiliary bracket 40 is a support member interposed between the BSA bracket 30 and the rear surface portion 20B of the fender 20 along the vehicle length direction.

[0072] The auxiliary bracket 40 is formed of a flat plate member having a surface extending in both the vehicle length direction and the up - down direction from the viewpoint of suppressing external forces acting on the BSA bracket 30 in the vehicle length direction (front - rear direction).

[0073] One end 40A of the auxiliary bracket 40 in the vehicle length direction is fixed to the BSA bracket 30. The fixing position of the auxiliary bracket 40 to the BSA bracket 30 is set, for example, near the other end 30B of the BSA bracket 30 and closer to the vehicle width direction inner side than the mounting position of the holding member 31.

[0074] The other end 40B of the auxiliary bracket 40 in the vehicle length direction is fixed to the rear surface portion 20B of the fender 20. Specifically, at the other end 40B in the vehicle length direction of the auxiliary bracket 40, it is fixed (fastened together) to the rear surface side support member 21 that fixes the rear surface portion 20B of the fender 20 via the support fittings 21A, 21B. That is, the auxiliary bracket 40 connects the BSA bracket 30 and the rear surface side support member 21 in the vehicle length direction (front - rear direction).

[0075] [2. Function and Effect]

[0076] The present embodiment described above has the following function and effect.

[0077] The mounting structure of the detection device 1 in this application example includes the above-mentioned detection device 1, a fender 20, and a BSA bracket 30. In the mounting structure of this detection device 1, the BSA bracket 30 is located at a position in front of the rear surface portion 20B of the fender 20, and is arranged to overlap with the outer side surface portion 20A when viewed from the outside in the vehicle width direction, and the detection device 1 is cantilever-supported in a state of being disposed in the opening 24 of the outer side surface portion 20A.

[0078] Thus, since the BSA bracket 30 is disposed inside the fender 20, the detection device 1 can be mounted inside the fender 20. Even with such a structure in which the BSA bracket 30 is disposed inside the fender 20, the detection device 1 can irradiate the radar outward from the opening 24 of the outer side surface portion 20A. Therefore, the detection device 1 can be appropriately mounted on the fender 20. Thus, the mountability of the detection device 1 can be ensured in the mounting structure of the detection device 1.

[0079] In addition, in the mounting structure of the detection device 1 in this application example, an auxiliary bracket 40 is interposed between the BSA bracket 30 and the rear surface portion 20B of the fender 20 in the vehicle length direction. Therefore, the BSA bracket 30 and the rear surface side support member 21 are connected via the auxiliary bracket 40. Thus, the auxiliary bracket 40 supports the BSA bracket 30 in a manner that suppresses the influence of external forces in the vehicle length direction. Consequently, the BSA bracket 30 is strengthened. As a result, vibration of the detection device 1 can be suppressed.

[0080] In addition, in the mounting structure of the detection device 1 in this application example, the BSA bracket 30 is disposed non-contact with respect to the opening 24 in a state where the detection device 1 is disposed in the opening 24. Thereby, friction between the BSA bracket 30 and the fender 20 can be prevented. In addition, it is difficult to transmit vibration from the fender 20 to the BSA bracket 30, so vibration of the detection device 1 can be suppressed.

[0081] In addition, in the mounting structure of the detection device 1 in this application example, the wiring 34 of the detection device 1 is disposed along the rear surface in the vehicle length direction of the BSA bracket 30. Therefore, the BSA bracket 30 functions as a protection member that prevents collision of flying stones or the like from the front with the wiring 34.

[0082] In addition, in the mounting structure of the detection device 1 in this application example, the BSA bracket 30 is disposed at a position in front of the rear surface side support member 21 and behind the front end side support member 23 in the vehicle length direction, and is disposed below the upper surface side support member 22. Therefore, the BSA bracket 30 can be disposed inside the fender 20 in a manner that does not interfere with the support members 21 to 23 that support the fender 20.

[0083] In addition, in the mounting structure of the detection device 1 of the present application example, the BSA bracket 30 is indirectly mounted on the vehicle body frame 10 via the upper surface side support member 22 disposed in front of the rear surface side support member 21 in the vehicle length direction and behind the front end side support member 23 in the vehicle length direction. Therefore, the BSA bracket 30 can be disposed inside the fender 20 in a manner that does not interfere with the support members 21 to 23 of the support fender 20, and the BSA bracket 30 can be stably mounted on the vehicle body frame 10 via the upper surface side support member 22.

[0084] [3. Others]

[0085] In the above-described embodiment, the configuration in which the BSA bracket 30 is indirectly mounted on the vehicle body frame 10 via the upper surface side support member 22 has been described. However, the BSA bracket 30 can also be directly mounted on the vehicle body frame 10 such as the longitudinal beam 11 and the cab bridge 12.

[0086] In addition, in addition to the auxiliary bracket 40, a reinforcing bracket for the BSA bracket 30 can be provided. As an example of the reinforcing bracket, a configuration can be cited in which a rear surface side sub-support member 21C (refer to Figure 1 ) that protrudes outward from the lower end of the cab bridge 12 extends outward in the vehicle width direction and connects the rear surface side sub-support member 21C and the BSA bracket 30.

[0087] In order to strengthen the BSA bracket 30 and the auxiliary bracket 40, ribs can be formed, or the BSA bracket 30 and the auxiliary bracket 40 can be formed of members with high rigidity having an L-shaped cross section or a C-shaped cross section.

[0088] In addition, there are various names for the device called BSA (Blind Spot Assist) in this specification. Such a device is also called BSM (Blind Spot Monitoring), etc., in addition to being called BSA. Therefore, the term "BSA" in this specification can also be replaced with other well-known names such as "BSM".

[0089] In addition, "BSA" in this specification may refer to a configuration that generates an alarm for the driver when a person, another vehicle, etc. present on the side of the present vehicle is detected, or may refer to a configuration that controls the present vehicle such as braking control and steering control of the present vehicle when a person, another vehicle, etc. present on the side of the present vehicle is detected, instead of or in addition to the above alarm.
