[0007] Summary of the invention

[0008] The problem that the invention aims to solve

[0009] Compared to visual information notifications, tactile information notifications, as described above, can reliably deliver information to the driver by delivering it to a part of the vehicle that the driver is constantly in contact with during driving.

[0010] However, if drivers need to receive information notifications while making steering maneuvers, they may find receiving these notifications cumbersome and therefore desire improvements.

[0011] Therefore, the object of the present invention is to facilitate the receipt of information notifications in a vehicle information notification device that provides tactile information notifications to the driver.

[0012] Solution for solving the problem

[0013] As a solution to the aforementioned problem, the vehicle information notification device of the present invention provides a movable part (56, 57) that operates via an actuator (105L, 105R) on at least one of the left and right outer sides of the vehicle body (1A) supporting the steering system component (10A) as a steerable vehicle body (1A). The movable part (56, 57) has an outer surface (56e, 57e) capable of contacting the driver's body, and by causing the outer surface (56e, 57e) to operate in a predetermined manner, the movable part (56, 57) notifies the driver of predetermined information.

[0014] According to this structure, at least one of the two outer sides of the vehicle body has a movable part. Through the operation of this movable part, predetermined information can be communicated to the driver's body. The movable part is separate from the steering system components (particularly the handlebars). Therefore, the communication of information based on the movable part is separated from steering operation, allowing the driver to easily receive the information.

[0015] In this invention, the movable part (56, 57) may have an outer surface (56e, 57e) that is positioned forward of the seat (19) and above the footrest (25) and capable of contacting the driver's leg.

[0016] According to this structure, an outer surface that can contact the driver's leg is positioned forward of the seat and above the footrest (the position where the driver clamps their knees) and is thus activated. This allows predetermined information to be communicated to the driver's leg.

[0017] In this invention, the movable parts (56, 57) may also operate in such a way that the outer surfaces (56e, 57e) move outward in the vehicle width direction.

[0018] According to this structure, the movable part operates by moving the outer surface outward in the vehicle width direction. This improves the reliability of contact with the driver's legs, allowing the driver to easily receive information notifications.

[0019] In this invention, the movable parts (56, 57) may also be respectively disposed on the left and right outer sides of the vehicle body (1L, 1R) and may operate independently on the left and right sides.

[0020] According to this structure, the left and right movable parts operate independently of each other, thus allowing for the combination of different actions of the left and right movable parts. This enables the driver to be notified of more information and increases the variety of information being communicated.

[0021] In this invention, the vehicle information notification device may also have an operation intervention function that can intervene in the operation performed by the driver, and the movable part (56, 57) works in conjunction with the operation intervention function.

[0022] This structure allows the movable part to operate in conjunction with the operational intervention function for driver input. Thus, the operation of the movable part can notify the driver of the operational intervention function's status.

[0023] In this invention, the movable part (56, 57) may also start working at a time (ta, te) earlier than the start time (tb, tf) of the operation intervention function when the operation intervention function is working.

[0024] According to this structure, the movable part begins to operate earlier than the start of the operation intervention function. Therefore, the driver can be notified in advance of the start of the operation intervention function.

[0025] In this invention, the vehicle information notification device may also have at least one of a steering intervention function and a braking intervention function as the operation intervention function.

[0026] According to this structure, at least one of the steering intervention function and the braking intervention function in the operation intervention function is activated. Thus, the driver can be notified through the operation of the movable part.

[0027] In this invention, the movable parts (56, 57) on the left and right sides may also be activated when the braking intervention function is in operation.

[0028] According to this structure, the operation of the brake intervention function is communicated to the driver through the movement of the movable parts on both the left and right sides. This improves the reliability of the notification regarding the operation of the brake intervention function, which is prone to triggering driver input.

[0029] In this invention, the movable parts (56, 57) on the left and right sides may also be activated when the steering intervention function is in operation.

[0030] According to this structure, the driver is notified of the steering intervention function's operation by the movement of one of the movable parts, either the left or right. Thus, by determining which movable part is activated, information including the steering direction based on the steering intervention function can be communicated to the driver.

[0031] In this invention, the steering intervention function may also have a route-changing function that changes the vehicle's travel path to either the left or right. Alternatively, the movable parts (56, 57) may operate in a manner that moves the outer surfaces (56e, 57e) outward in the vehicle width direction. Alternatively, when the steering intervention function is activated, the movable parts (56, 57) on the side that changes the vehicle's travel path may operate in a manner that moves the outer surfaces (56e, 57e) outward in the vehicle width direction.

[0032] According to this structure, when the steering intervention function's travel path change function is activated, the movable part on the travel path change side of the vehicle operates by moving its outer surface outward in the vehicle width direction. This causes the driver's leg on the travel path change side to open outward in the vehicle width direction, promoting a suitable steering posture.

[0033] In this invention, the movable parts (56, 57) may also operate as follows during a waiting state before the operation intervention function is activated and before the operation intervention function is activated: that is, the movable parts (56, 57) operate in a different mode than when the operation intervention function is in operation.

[0034] According to this structure, the system has a waiting state for the operation intervention function before it is activated. In this waiting state, the movable part operates in a different manner than when the operation intervention function is actively operating. This allows the driver to be notified that the operation intervention function is in a waiting state.

[0035] In this invention, the vehicle information notification device may also include a display device (66, 67) that is operatively linked to the movable part (56, 57) for displaying predetermined information to the driver.

[0036] Based on this structure, a display device is also included that is linked to the operation of the movable part. Therefore, by utilizing the operation of the movable part and the display on the display device, information can be more reliably communicated to the driver.

[0037] Invention Effects

[0038] According to the present invention, in a vehicle information notification device that provides tactile information notification to the driver, information notification can be easily received. Attached Figure Description

[0054] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the directions (front, back, left, right, etc.) used in the following description are the same as the directions in the vehicle described below. Furthermore, in the drawings used in the following description, arrows indicating the front of the vehicle (FR), the left side of the vehicle (LH), and the top of the vehicle (UP) are shown in appropriate locations.

[0055] <Vehicle as a whole>

[0056] Figure 1 A motorized two-wheeled vehicle 1 is shown as an example of a vehicle according to this embodiment. The motorized two-wheeled vehicle 1 includes a front wheel (steering wheel) 3 steered via handlebars 2 and a rear wheel (drive wheel) 4 driven by a power unit 20. The motorized two-wheeled vehicle 1 is a straddle-type vehicle in which the driver straddles the vehicle. The motorized two-wheeled vehicle 1 is capable of swaying (tilting) to the left and right (lateral tilting direction) with reference to the contact points of the front and rear wheels 3 and 4. The vehicle of this embodiment is not limited to a motorized two-wheeled vehicle that turns in the direction that causes the vehicle to tilt. The vehicle of this embodiment includes vehicles that turn by steering the steering wheel without tilting the vehicle.

[0057] The motorized two-wheeled vehicle 1 includes a steering system component 10A comprising handlebars 2 and a front wheel 3. The steering system component 10A is steerably supported on a head tube 6. The head tube 6 is located at the front end of the frame 5, which forms the skeleton of the motorized two-wheeled vehicle 1. The front wheel 3 is supported on the lower ends of a pair of left and right front forks 10 in the steering system component 10A. The frame 5 is surrounded by a body cover 12. In the motorized two-wheeled vehicle 1, the main body of the vehicle, including the frame 5, etc. (the main body of the vehicle that supports the steering system component 10A to enable steering), is referred to as the body 1A.

[0058] The frame 5 has a head tube 6, a pair of main frames 7, a pair of pivot frames 8, and a pair of seat frames 9.

[0059] The head tube 6 supports the steering system component 10A to enable steering. The left and right main frames 7 extend from the head tube 6, with the front higher than the rear. The left and right pivot frames 8 extend downward from the rear ends of the left and right main frames 7, respectively. The left and right seat frames 9 extend from the upper parts of the left and right pivot frames 8, with the front lower than the rear.

[0060] A pivot 8a, extending along the vehicle width, is mounted on the left and right pivot frames 8. The front end of the swing arm 11 is supported on the left and right pivot frames 8 via the pivot 8a, allowing it to swing up and down. The rear wheel 4 is supported on the rear end of the swing arm 11. A buffer unit (not shown) is mounted between the frame 5 and the swing arm 11 as a shock absorber.

[0061] A fuel tank 18 is supported on the upper part of the left and right main frames 7. A seat 19 is supported behind the fuel tank 18 by the left and right seat frames 9. A pair of footrests 25 are arranged below the seat 19 for the driver to place his feet.

[0062] The power unit 20 of the motorized two-wheeled vehicle 1 is supported on the left and right main frames 7 and the left and right pivot frames 8. The output shaft of the power unit 20 is connected to the rear wheel 4 via a chain-type transmission mechanism (not shown) to transmit power.

[0063] The power unit 20 integrates an engine (internal combustion engine) 13 that serves as a prime mover and a transmission 21 connected to the rear of the engine 13.

[0064] The motorized two-wheeled vehicle 1 is equipped with a front wheel brake 3B for braking the front wheel 3 and a rear wheel brake 4B for braking the rear wheel 4. Both the front wheel brake 3B and the rear wheel brake 4B are disc brakes.

[0065] The front wheel brake 3B and the rear wheel brake 4B are operated by the brake lever and brake pedal, which serve as brake operating elements, to properly brake the rotation of the front wheel 3 and the rear wheel 4. Additionally, the front wheel brake 3B and the rear wheel brake 4B are also braked by the brake actuator 102 described later (see reference). Figure 4 The mechanism is designed to properly brake the rotation of the front wheel 3 and the rear wheel 4.

[0066] The motorized two-wheeled vehicle 1 is equipped with a driving support device 70 (see reference) that supports the driver's driving operations (in this embodiment, steering operations to steer the front wheels 3 and braking operations to brake the front wheels 3 and the rear wheels 4). Figure 4 The driving support device 70 includes a control device 71 that controls the function of automatically intervening in the driver's driving operations (automatic operation intervention function). The automatic operation intervention function includes automatic steering intervention function and automatic braking intervention function. The driving support device 70 will be described in detail later.

[0067] Figure 2 The front of the vehicle is shown as viewed from the driver's perspective. The upper parts of the left and right front forks 10 are supported on the head tube 6 via a steering rod 31. The left and right front forks 10 are telescopic shock absorbers. The steering rod 31 has a top bridge 32 and a bottom bridge 33 that connect the upper parts of the left and right front forks 10 to each other, and a rod axle (steering axle) 34 that passes through the head tube 6. The front of the vehicle is covered by a front cover 27 of the body cover 12.

[0068] For example, the handlebars 2 of the motorized two-wheeled vehicle 1 are split handlebars, with a pair of right handlebars 36 and left handlebars 37. For example, the right handlebars 36 and left handlebars 37 are respectively mounted on the upper part of the left and right front forks 10 below the top bridge 32.

[0069] Refer to together Figure 1 , Figure 5 The vehicle body 1A has a pair of left and right outer body portions 1L and 1R facing outwards in the vehicle width direction. Movable portions 56 and 57, operated by actuators 105L and 105R, are located on the left and right outer body portions 1L and 1R. The movable portions 56 and 57 are positioned forward of the seat 19 and above the footrest 25. The driver, seated on the seat 19 with feet on the footrest 25, extends their thighs outwards towards the left and right sides of the fuel tank 18. Additionally, the knees of the legs are bent outwards towards the footrest 25. The movable portions 56 and 57 overlap with these legs when viewed from the side of the vehicle. The outer surfaces 56e and 57e of each movable portion 56 and 57 facing outwards in the vehicle width direction can contact the driver's legs from the inside in the vehicle width direction.

[0070] Each movable part 56, 57 functions as a mechanism for notifying the driver's legs of predetermined information by causing the outer surfaces 56e, 57e to operate in a predetermined manner. In this embodiment, each movable part 56, 57 functions as a mechanism for notifying the driver of information related to automatic operation intervention. Each movable part 56, 57 operates by moving the outer surfaces 56e, 57e outward in the vehicle width direction. Each movable part 56, 57 includes a leg pressing device 72 that presses the driver's legs from the inside in the vehicle width direction.

[0071] The leg pressing device 72 includes: a right leg pressing part 72R provided on the right outer side 1R of the vehicle body; a left leg pressing part 72L provided on the left outer side 1L of the vehicle body; and a leg pressing control part 89 described later (see reference). Figure 4 The right leg pressing part 72R and the left leg pressing part 72L allow the plate-shaped right movable part (movable part) 56 and left movable part 57, which are located along the outer side of the vehicle body, to move (swing) in the vehicle width direction. When viewed from the side of the vehicle, the right movable part 56 and left movable part 57 extend at an angle, higher in the front and lower in the rear, along the upper edge of the main frame 7. The right movable part 56 and left movable part 57 can contact the driver's left and right legs (thighs, knees, etc.) from the inside in the vehicle width direction.

[0072] The positions where the right movable part 56 and the left movable part 57 are located in the vehicle body 1A are where the driver clamps the vehicle body 1A with his left and right legs (the so-called knee clamping position). A pair of left and right leg clamping parts 120 are provided on the right outer side 1R and the left outer side 1L of the vehicle body, forming a pair to match the driver's left and right legs. The right movable part 56 and the left movable part 57 are respectively arranged in the left and right leg clamping parts 120.

[0073] Therefore, if the driver adopts a normal riding posture with their knees clamped together, the driver's left and right legs will naturally contact the outer surfaces 56e and 57e of the right movable part 56 and the left movable part 57. The right movable part 56 and the left movable part 57 will then move from their initial position P0 (refer to...) Figure 5 ) become work positions P1 and P2 (refer to) Figure 6 , Figure 7 The system operates in a manner described above. The initial position P0 is a position in which the outer sides 56e and 57e are arranged along the outer sides of the vehicle body outer portions 1R and 1L. The working positions P1 and P2 are positions in which the outer sides 56e and 57e are moved (swinged) outward in the vehicle width direction. When the right movable part 56 and the left movable part 57 are in the working positions P1 and P2, the left and right outer sides 56e and 57e protrude outward in the vehicle width direction from the other general surfaces of the leg clamping part 120.

[0074] The working positions P1 and P2 include the first working position P1 (refer to...). Figure 6 ) and second working position P2 (refer to Figure 7 The first working position P1 is a position where the outer surfaces 56e and 57e move (swing) a first predetermined amount S1 from the initial position P0 outward in the vehicle width direction. The second working position P2 is a position where the outer surfaces 56e and 57e move (swing) a second predetermined amount S2 further outward in the vehicle width direction from the first working position P1. The right movable part 56 and the left movable part 57, by moving (swinging) outward in the vehicle width direction, press against the driver's leg from the inside in the vehicle width direction. Through this pressing, information such as the automatic operation intervention function being activated is communicated to the driver.

[0075] Reference Figure 2 An instrument panel 61 is mounted in front of the front fork 10. The instrument panel 61 is supported on the frame 5 or the front cover 27. The instrument panel 61 includes, for example, a display screen 62 such as an LCD screen that displays images of vehicle speed and engine speed, and a group of indicator lights 63 arranged around the display screen 62 to notify various information.

[0076] The indicator light group 63 includes a right indicator light (display device) 66 arranged on the right side of the display screen 62 and a left indicator light (display device) 67 arranged on the left side of the display screen 62. The right indicator light 66 illuminates in conjunction with the operation of the right movable part 56. The left indicator light 67 illuminates in conjunction with the operation of the left movable part 57. The display screen 62 notifies the driver of predetermined information by displaying a predetermined image. The indicator light group 63 notifies the driver of predetermined information by displaying predetermined illumination (lighting up or flashing).

[0077] Figure 3 The periphery of the top bridge 32 is shown as viewed from above the axial direction of the rod shaft 34.

[0078] For the steering system component 10A, steering input is automatically performed separately from the driver's operation of the handlebars 2 via the steering assist device 73.

[0079] The steering assist device 73 includes a steering actuator 74, an arm 75, a connecting rod 76, and a steering control unit 77.

[0080] The steering actuator 74 includes an electric motor that serves as the drive source for the automatic steering intervention function. The steering actuator 74 is, for example, fixed to the vehicle frame 5. The base end of the arm 75 is integrally rotatably fixed to the drive shaft 74a, which serves as the output shaft of the steering actuator 74. One end of the connecting rod 76 is pivotally connected to the front end of the arm 75 via a first connecting pin 78. The other end of the connecting rod 76 is pivotally connected to the rod connection portion 32a provided on the top bridge 32 via a second connecting pin 79.

[0081] The operation of the steering actuator 74 is controlled by the steering control unit 77. The output of the steering actuator 74 (the rotational torque of the drive shaft 74a) is transmitted to the top bridge 32 via the arm 75 and the connecting rod 76. As a result, the steering actuator 74 causes the steering system components 10A to generate steering torque (auxiliary torque).

[0082] <Driver Support Device>

[0083] like Figure 4 As shown, the driving support device 70 includes a control device 71, various sensor types 81, and various device types 82. The control device 71 controls the operation of the various device types 82 based on the detection information obtained from the various sensor types 81.

[0084] The control device 71 may consist of one or more ECUs (Electronic Control Units). The control device 71 may also implement at least a portion of its functionality through a combination of software and hardware.

[0085] The control device 71 includes an engine control unit 85, a steering control unit 77, a brake control unit 87, a display control unit 88, and a leg press control unit 89.

[0086] Various sensor types 81 include a steering torque sensor 91, a steering angle sensor 92, a vehicle acceleration sensor 93, a vehicle speed sensor 94, a camera device 96, and a radar device 97.

[0087] The steering torque sensor 91 is, for example, a magnetostrictive torque sensor disposed between the handlebar 2 and other steering system components 10A. The steering torque sensor 91 detects the torque (steering input) input from the handlebar 2 to the other steering system components 10A.

[0088] Steering angle sensor 92 is, for example, a potentiometer mounted on the steering shaft (shaft 34). Steering angle sensor 92 detects the rotation angle (steering angle) of the steering shaft relative to the vehicle body.

[0089] The vehicle body acceleration sensor 93 is a five-axis or six-axis IMU (Inertial Measurement Unit). The vehicle body acceleration sensor 93 detects the angular velocities of the vehicle body along three axes (roll axis, pitch axis, and yaw axis), and can then estimate the angle and acceleration based on the results.

[0090] The vehicle speed sensor 94, for example, detects the rotational speed of the output shaft of the power unit 20. Based on this rotational speed, the vehicle speed sensor 94 can detect the rotational speed of the rear wheel 4, and even the speed of the motorized two-wheeled vehicle 1.

[0091] The camera device 96 is equipped with a camera using a solid-state imaging element such as a CCD or CMOS. The camera device 96 uses the camera to periodically photograph, for example, the perimeter (e.g., front, back, left, and right) of the motorized two-wheeled vehicle 1. The camera device 96 generates image data from the captured images through image processing such as filtering and binarization.

[0092] Radar device 97 radiates millimeter-wave and other radio waves around the motorized two-wheeled vehicle 1. Radar device 97 detects radio waves (reflected waves) reflected by objects around the vehicle. Radar device 97 is at least able to detect the position (distance and orientation relative to the motorized two-wheeled vehicle 1) and speed of the object relative to the front, rear, left, and right sides of the motorized two-wheeled vehicle 1.

[0093] Information from the aforementioned camera device 96 and radar device 97 is used to identify the position, type, speed, etc., of objects in the detection direction. Based on this identification, driver assistance control and automatic driving control of the motorized two-wheeled vehicle 1 are performed.

[0094] Various types of devices 82 include a steering actuator 74, a brake actuator 102, an indicator light group 63, and a movable part actuator 105.

[0095] The steering actuator 74 generates steering torque separately from the driver's operation of the handlebars 2, causing the front wheels 3 to turn. The steering actuator 74 can also function as a shock absorber for the steering mechanism.

[0096] The brake actuator 102 supplies hydraulic pressure separately to the front wheel brakes 3B and the rear wheel brakes 4B, independent of the driver's operation of the brake operating components, to activate the front wheel brakes 3B and the rear wheel brakes 4B. The brake actuator 102 can also function as a control unit for the ABS (Anti-lock Brake System). The brake actuator 102 can be connected to brake piping branching off from the normal brake circuit.

[0097] The indicator light group 63 includes a right indicator light 66 and a left indicator light 67. The right indicator light 66 and the left indicator light 67 illuminate in conjunction with the operation of the movable part actuator 105.

[0098] The movable part actuator 105 includes a right movable part actuator 105R and a left movable part actuator 105L. The right movable part actuator 105R drives the right movable part 56 located on the right side of the vehicle body. The left movable part actuator 105L drives the left movable part 57 located on the left side of the vehicle body.

[0099] The control device 71 will be described next.

[0100] The engine control unit 85 controls the output of the engine 13 based on factors such as throttle opening, intake negative pressure, fuel injection quantity, valve timing, and ignition timing. Furthermore, by controlling the output of the engine 13, the speed of the motorized two-wheeled vehicle 1 is changed through the crankshaft speed of the engine 13 and the gear ratio of the transmission 21.

[0101] The steering control unit 77 controls the operation of the steering actuator 74 based on signals and information such as the steering torque signal detected by the steering torque sensor 91, the angular velocity signal detected by the vehicle acceleration sensor 93, the vehicle speed signal detected by the vehicle speed sensor 94, and detection information detected by the camera device 96 and the radar device 97. As a result, an auxiliary torque is applied to the steering system component 10A. This auxiliary torque assists in steering the front wheels 3, which act as steering wheels. Thus, the steering control unit 77 controls the automatic steering intervention function.

[0102] The brake control unit 87 controls the operation of the brake actuator 102 based on engine output, vehicle speed signals detected by the vehicle speed sensor 94, and detection information detected by the camera device 96 and radar device 97. As a result, the front wheel brakes 3B and the rear wheel brakes 4B generate auxiliary braking force. This auxiliary braking force assists in braking the front wheels 3 and rear wheels 4. Thus, the brake control unit 87 controls the automatic braking intervention function.

[0103] The display control unit 88 controls the illumination (lighting up or flashing) of the right indicator light 66 and the left indicator light 67 in conjunction with the following functions: the control of the automatic steering intervention function based on the steering control unit 77, and the control of the automatic braking intervention function based on the brake control unit 87.

[0104] The leg press control unit 89 controls the operation of the right movable actuator 105R and the left movable actuator 105L, along with the control of the following functions: the control of the automatic steering intervention function based on the steering control unit 77, and the control of the automatic braking intervention function based on the brake control unit 87. The movement of the right movable part 56 and the left movable part 57 outward in the vehicle width direction is controlled by controlling the operation of the right movable actuator 105R and the left movable actuator 105L.

[0105] The display control unit 88 and the leg pressing control unit 89 simultaneously perform their respective controls when the steering actuator 74 and the brake actuator 102 are in operation.

[0106] The aforementioned engine control unit 85, steering control unit 77, brake control unit 87, display control unit 88, and leg press control unit 89 are all equipped with microcomputers and are configured to communicate freely with each other.

[0107] <Leg Pressing Section>

[0108] The following is an explanation. Figures 5-7 The structure of the left leg pressing part 72L is shown. The right leg pressing part 72R has a symmetrical structure and is therefore omitted from description.

[0109] The left leg pressing part 72L includes a left movable part actuator (actuator) 105L, a circular plate 106, a connecting rod member 107, and a left movable part 57.

[0110] The left movable actuator 105L is an electric motor disposed between the upper edge of the main frame 7 and the fuel tank 18. The left movable actuator 105L is fixed to the main frame 7 or the fuel tank 18. For example, the electric motor is a stepper motor capable of controlling the rotation angle of the rotating shaft 105a to a predetermined angle. For example, when the rotating shaft 105a stops at a predetermined rotation angle, the electric motor has a holding force that maintains the rotating shaft 105a at that rotation angle. The circular plate 106 is integrally rotatably mounted on the rotating shaft 105a of the left movable actuator 105. The rotating shaft 105a extends in the vehicle's longitudinal direction.

[0111] The upper end of the left movable part 57 is supported on the lower end of the side cover 111. The side cover 111 is positioned above the main frame 7. The left movable part 57 is supported so that it can swing with its upper edge, which extends along the longitudinal direction of the vehicle (extending along the upper edge of the main frame 7), as a fulcrum. The outer side 57e of the left movable part 57 can contact the legs of the driver riding in the motorized two-wheeled vehicle 1 from the inside in the vehicle width direction.

[0112] Figure 5 The left movable part 57 shown is in the position where it is swung to the innermost side in the vehicle width direction. This position of the left movable part 57 is called the initial position P0 or the closed position.

[0113] A connecting rod connection portion 57c protrudes from the inner side of the left movable part 57 in the vehicle width direction. A circular plate 106 is connected to the connecting rod connection portion 57c via a connecting rod member 107. One end of the connecting rod member 107 is pivotally connected to the outer periphery of the circular plate 106 via a first support shaft 113. The other end of the connecting rod member 107 is pivotally connected to the connecting rod connection portion 57c of the left movable part 57 via a second support shaft 114.

[0114] It should be noted that, in Figure 4 The block diagram shows the right movable actuator (actuator) 105R of the right leg pressing part 72R. The right movable actuator 105R is an electric motor with the same structure as the left movable actuator 105L. The right movable part 57 has an outer surface 56e that can contact the leg of the driver in the vehicle.

[0115] like Figure 6 As shown, in the left leg pressing part 72L, when the left movable part actuator 105L moves from... Figure 5 When operating in this state, the following action occurs: The circular plate 106 rotates together with the rotation shaft 105a of the left movable actuator 105L in the direction of arrow A.

[0116] With this rotation, the connecting rod member 107 is pressed outward in the vehicle width direction, pushing the left movable part 57 outward in the vehicle width direction. As a result, the left movable part 57 swings with its upper end as the pivot point, moving as follows. That is, the left movable part 57 moves from the point indicated by the double-dotted line... Figure 5 The initial position P0 (closed position) is moved to the first working position P1 (LOW position) indicated by the solid line. The left movable part 57 protrudes a first predetermined amount S1 outward in the vehicle width direction by swinging from the initial position P0 to the first working position P1.

[0117] like Figure 7 As shown, at the left leg pressing part 72L, when the left movable part actuator 105L moves from... Figure 6 When the state is further operated, the following action occurs. That is, the circular plate 106 and the rotation shaft 105a of the left movable actuator 105L rotate further in the direction of arrow A.

[0118] With this rotation, the connecting rod member 107 is further pressed outward in the vehicle width direction, further pressing the left movable part 57 outward in the vehicle width direction. As a result, the left movable part 57 swings more widely with its upper end as the pivot point, moving as follows. That is, the left movable part 57 moves from the point indicated by the double-dotted line... Figure 6 The left movable part 57 moves from the first working position P1 (LOW position) to the second working position P2 (HIGH position), indicated by the solid line. The left movable part 57 protrudes a second predetermined amount S2 outward in the vehicle width direction by swinging from the first working position P1 to the second working position P2. For example, the second working position P2 is the maximum outward protrusion position of the left movable part 57 in the vehicle width direction.

[0119] The left movable part 57 (and the right movable part 56) can move in two phases: a LOW position with a small amount of protrusion outward in the vehicle width direction and a HIGH position with a large amount of protrusion outward in the vehicle width direction. Therefore, regarding the automatic operation intervention function, multiple and different types of information can be communicated to the driver.

[0120] It should be noted that the function of the left movable part 57 (and the right movable part 56) in applying tactile stimulation to the driver's leg is not limited to a structure in which the upper end is used as the pivot point for swinging. For example, the left movable part 57 (and the right movable part 56) can also swing with the lower end or the front and rear ends as the pivot points. In addition, the left movable part 57 (and the right movable part 56) can also move approximately parallel as a whole, or perform various other actions, or cause the outer surfaces 56e and 57e to vibrate, or combine multiple of the aforementioned functions.

[0121] Explain the function of the left and right leg pressing sections 72L and 72R as described above.

[0122] First, when the driving support device 70 system is not activated, such as Figure 5 As shown, the right movable part 56 and the left movable part 57 are arranged in the initial position P0. That is, the right movable part 56 and the left movable part 57 are arranged along the outer surfaces of the right outer side 1R and the left outer side 1L of the motorized two-wheeled vehicle 1. In the initial position P0, the right movable part 56 and the left movable part 57 are in the following state on the right outer side 1R and the left outer side 1L: that is, the right movable part 56 and the left movable part 57, together with the main frame 7, the fuel tank 18 and other body components such as the body cover, form a substantially continuous outer surface.

[0123] The right movable part 56 and the left movable part 57 are positioned where the driver's legs clamp around the vehicle body 1A (the so-called knee-clamping position). When the driving support device 70 is not activated, the right movable part 56 and the left movable part 57 do not protrude from the outer surfaces of the right outer side 1R and the left outer side 1L of the vehicle body. Therefore, when the driver clamps their knees around the right outer side 1R and the left outer side 1L of the vehicle body, they will not be particularly aware of the presence of the right movable part 56 and the left movable part 57, and can drive without discomfort.

[0124] Next, we will explain the situation when the driver support device 70 is activated and the automatic operation intervention function is in a non-operating state (hereinafter referred to as the waiting state). At this time, as... Figure 6 As shown, the right movable part 56 and the left movable part 57 are configured to protrude a first predetermined amount S1 from the outer surfaces of the right outer side 1R and the left outer side 1L of the motorized two-wheeled vehicle 1 in the vehicle width direction.

[0125] In the waiting state, the right movable part 56 and the left movable part 57 repeatedly reciprocate between the initial position P0 and the first working position P1. The first working position P1 is a position that protrudes a first predetermined amount S1 outward in the vehicle width direction from the initial position P0. Therefore, the driver is aware of the presence of the right movable part 56 and the left movable part 57 when their legs are clamped together with their knees on the right outer side 1R and the left outer side 1L of the vehicle body. Therefore, the driver can recognize that the driving support device 70 is activated.

[0126] Next, we will explain the situation when the steering intervention function and braking intervention function of the automatic operation intervention function are activated, starting from the waiting state of the driving support device 70. At this time, as... Figure 7 As shown, at least one of the right movable portion 56 and the left movable portion 57 is configured to protrude further outward in the vehicle width direction from the first working position P1. At this time, the right movable portion 56 and the left movable portion 57 are configured to protrude further outward in the vehicle width direction from the first working position P1 to a second working position P2 by a second predetermined amount S2.

[0127] Thus, the driver can sense the movement of at least one of the right movable part 56 and the left movable part 57 and recognize that the automatic operation intervention function is in operation.

[0128] In this embodiment, during the operation of the automatic operation intervention function, at least one of the right movable part 56 and the left movable part 57 remains in the state of being moved to the second working position P2. However, the driving support device is not limited to this structure. For example, during the operation of the automatic operation intervention function, at least one of the right movable part 56 and the left movable part 57 may repeatedly reciprocate between the first working position P1 and the second working position P2.

[0129] Explain the function of the driving support device 70 described above.

[0130] Figure 8 The system of the driving support device 70 is shown in a state where it is activated but the automatic operation intervention function is not in operation, indicating a waiting state. In the waiting state, the main switch (power supply) of the motorized two-wheeled vehicle 1 is turned on, and the operation switch of the driving support device 70 is turned on, thus enabling the automatic operation intervention function to operate. In the waiting state, various sensors 81 monitor various parameters used for the operation of the automatic operation intervention function. Based on this monitoring information, the automatic operation intervention function can start operating immediately.

[0131] In the waiting state, the right movable part 56 of the right leg pressing part 72R and the left movable part 57 of the left leg pressing part 72L work synchronously. At this time, the right movable part 56 and the left movable part 57 perform a reciprocating movement (swing) in the vehicle width direction. Specifically, the right movable part 56 and the left movable part 57 perform a forward movement from the initial position P0 (closed position) to the first working position P1 (LOW position) and a return movement from the first working position P1 back to the initial position P0.

[0132] Additionally, at this time, the right indicator light 66 and the left indicator light 67 of the instrument unit 61 illuminate (flash) synchronously with the movement of the right movable part 56 and the left movable part 57. Specifically, the right indicator light 66 and the left indicator light 67 illuminate when the right movable part 56 and the left movable part 57 move from the initial position P0 to the first working position P1. Furthermore, the right indicator light 66 and the left indicator light 67 turn off when returning from the first working position P1 to the initial position P0. The flashing cycle of the right indicator light 66 and the left indicator light 67 in the waiting state (which is also the working cycle of the left and right movable parts 56 and 57) is set as the first cycle.

[0133] In this way, tactile stimulation is applied to the driver's legs, and vision is also used to notify the driver that the system is starting up.

[0134] Figure 9 The time elapsed during the operation of the movable actuator 105, etc., in the waiting state is shown.

[0135] Figure 9 The vertical axis of the line graph shows the operating status (ON (working) and OFF (not working)) of the actuators 105L and 105R of the left and right movable parts 56 and 57, as well as the left and right indicator lights 66 and 67. The vertical axis also shows the operating status (ON and OFF) of steering or braking intervention.

[0136] With the left and right actuators 105L and 105R in operation, the left and right movable parts 56 and 57 are set to OFF when they are in the closed position, and set to ON when they are in the LOW and HIGH positions. Furthermore, in the line graph, the left and right movable parts 56 and 57 in the LOW position are marked as "L", and the left and right movable parts 56 and 57 in the HIGH position are marked as "H". The horizontal axis of the line graph represents time T (sec).

[0137] In the diagram, "RH movable part" represents the right movable actuator 105R, and "LH movable part" represents the left movable actuator 105L. Additionally, "indRH" represents the right indicator light 66, and "indLH" represents the left indicator light 67. It should be noted that... Figure 11 , Figure 13 , Figure 15 In the line graph, the vertical and horizontal axes are also... Figure 9 The vertical and horizontal axes of the line graph shown are the same.

[0138] In the aforementioned waiting state, the right movable part actuator 105R and the left movable part actuator 105L operate intermittently at the same time. In the waiting state, the right movable part actuator 105R and the left movable part actuator 105L open the left and right movable parts 56 and 57 from the initial position P0 to the first working position P1. This operation is performed for a predetermined time T1 (e.g., 0.5 to 1 second). In the waiting state, the right movable part actuator 105R and the left movable part actuator 105L open the left and right movable parts 56 and 57. This operation is repeated at predetermined time intervals T2 (e.g., approximately 2 seconds).

[0139] The right movable part 56 and the left movable part 57, which have opened outward in the vehicle width direction from their initial position P0, contact and press against the driver's left and right legs (thighs, knees, etc.) from the inside in the vehicle width direction. In the waiting state, the right movable part 56 and the left movable part 57 move to a LOW position, protruding beyond the leg clamping part 120 surrounding them. At this time, the right movable part 56 and the left movable part 57 open the driver's left and right legs outward in the vehicle width direction compared to their closed position. As a result, the driver recognizes the waiting state based on the operation of the right movable part 56 and the left movable part 57.

[0140] At this time, the right movable part 56 and the left movable part 57 move outward in the vehicle width direction, pressing down on the driver's left and right legs. This increases the force with which the driver grips the vehicle body through their reaction. Furthermore, at this time, the driver overcomes the pressing and grips the vehicle body more forcefully. Thus, the driver's force in maintaining the vehicle body with their left and right legs increases, creating a riding posture suitable for automatic operation intervention functions.

[0141] Furthermore, the right indicator light 66 and the left indicator light 67 flash intermittently in sync with the right movable part 56 and the left movable part 57. That is, the right indicator light 66 and the left indicator light 67 repeatedly illuminate for a time interval T1, spaced apart by a time interval T2. In this way, the right movable part 56 and the left movable part 57 are linked with the right indicator light 66 and the left indicator light 67.

[0142] In the waiting state, the automatic intervention functions of steering intervention and braking intervention are not activated and remain in the OFF state.

[0143] Figure 10 This shows the state in which the driving support device 70 activates the automatic braking intervention function from the waiting state, in order to brake the motorized two-wheeled vehicle 1.

[0144] The automatic braking intervention function in this embodiment is not related in the left-right direction, therefore both the right movable part 56 and the left movable part 57 are activated. At this time, both the right movable part 56 and the left movable part 57 are moved from the closed position to the HIGH position. The automatic braking intervention function anticipates emergency situations that may induce driver physical reactions, therefore both the right movable part 56 and the left movable part 57 are activated. At this time, the right movable part 56 and the left movable part 57 maintain a continuous operating state without time intervals, rather than operating intermittently.

[0145] In addition, during the operation of the right movable part 56 and the left movable part 57, the right indicator light 66 and the left indicator light 67 illuminate (flicker). This illumination is not limited to flashing; it can also be an illumination that is linked to the operation of the right movable part 56 and the left movable part 57.

[0146] When the aforementioned automatic braking intervention function is in operation, the right movable part 56 and the left movable part 57 operate more actively, in a manner different from the waiting state. Furthermore, the right indicator light 66 and the left indicator light 67 of the instrument panel 61 flash faster than in the waiting state.

[0147] Therefore, by using the tactile and visual sensations of the left and right legs as they clamp their knees around the vehicle, the driver can identify when the automatic braking intervention function is in operation.

[0148] When the automatic braking intervention function is in operation, the right movable part 56 and the left movable part 57 move to the HIGH position, which protrudes significantly more than the leg clamping parts 120 around them. As a result, by using the right movable part 56 and the left movable part 57, which protrude more than in the LOW position, the left and right legs are opened more outward in the left and right vehicle width direction compared to the LOW position. This allows the driver to more clearly recognize that the automatic braking intervention function is in operation.

[0149] At this time, the legs of both sides are pressed from the inside by the right movable part 56 and the left movable part 57, thereby producing the following effect: the holding force of the legs to keep the vehicle body is increased compared to the LOW position. As a result, it becomes a riding posture suitable for responding to the deceleration of the motorized two-wheeled vehicle 1 when the automatic braking intervention function is in operation.

[0150] Figure 11 The diagram illustrates the operation of the right movable actuator 105R and the left movable actuator 105L during automatic braking intervention.

[0151] When the automatic braking intervention function is activated due to an obstacle or other obstacle in front of the motorized two-wheeled vehicle 1, both the right movable actuator 105R and the left movable actuator 105L begin to operate. At this time, the right movable part 56 and the left movable part 57 move from the closed position to the HIGH position. This operation is continuously maintained without time intervals during the automatic braking intervention function's operation time T5.

[0152] Furthermore, during the operation of the right movable part 56 and the left movable part 57, both the right indicator light 66 and the left indicator light 67 begin to flash. Specifically, the right indicator light 66 and the left indicator light 67 repeatedly illuminate for a predetermined time T3 (e.g., 0.5 to 1 second). The illumination of time T3 is repeated at intervals of a predetermined time T4 (e.g., 0.5 to 1 second). Time T4 is shorter than time T2 in the waiting state. Time T3 can be the same as or shorter than time T1 in the waiting state.

[0153] Here, the timing te for the right movable part 56 and the left movable part 57 to start operating and for the right indicator light 66 and the left indicator light 67 to start flashing is set as follows: That is, the timing te is preceded by a time th (e.g., approximately 1 second) by the timing tf for the automatic braking intervention function to start operating. In other words, the operation of the right movable part 56 and the left movable part 57, and the flashing of the right indicator light 66 and the left indicator light 67, begin before the operation of the automatic braking intervention function. Therefore, the driver can be notified in advance that the automatic braking intervention function is about to begin operating.

[0154] It should be noted that the operation of the right movable part 56 and the left movable part 57, as well as the flashing of the right indicator light 66 and the left indicator light 67, stop simultaneously when the automatic braking intervention function stops.

[0155] Figure 12 This shows the state where the driving support device 70 activates the automatic steering intervention function from the waiting state, so that the driving path of the motorized two-wheeled vehicle 1 is oriented to the left.

[0156] For example, when the steering control unit 77 of the driving support device 70 determines that the motorized two-wheeled vehicle 1 is too close to the right side of the lane, it will make the motorized two-wheeled vehicle 1 return to the left side of its travel path.

[0157] At this time, the steering control unit 77 turns the front wheels 3 to the right via the steering actuator 74. That is, it turns the front wheels 3 to the opposite side of the side where the travel path of the motorized two-wheeled vehicle 1 is to be changed (reverse steering). As a result, the motorized two-wheeled vehicle 1 can be naturally turned in the direction of the change of travel path.

[0158] When the aforementioned automatic steering intervention function is in operation, only the left movable part 57 of the motorized two-wheeled vehicle 1, which changes the direction of travel (to the left), moves from the LOW position to the HIGH position. In addition, the left indicator light 67 of the instrument panel 61 flashes in a flashing pattern different from that in the waiting state.

[0159] Therefore, through the tactile and visual senses of the legs clamped between the knees and the vehicle body, the driver can identify the following points: that is, the driver can identify when the automatic steering intervention function is working and the direction the motorized two-wheeled vehicle 1 should be oriented.

[0160] The left movable part 57 opens the left leg to the outside (left side) in the vehicle width direction by pressing the occupant's left leg outward (to the left). This allows the driver to more clearly recognize when the automatic steering intervention function to the left of the vehicle is in operation. In addition, by opening the left leg to the left, the driver's center of gravity shifts to the left relative to the vehicle body, allowing for a posture suitable for left turns.

[0161] Figure 13 Showing automatic steering intervention function Figure 12 The operating mode of the right movable actuator 105R and the left movable actuator 105L during operation is shown.

[0162] Automatic steering intervention function Figure 12 During operation, only the left movable part actuator 105L is activated, causing the left movable part 57 to move from the LOW position to the HIGH position.

[0163] Additionally, during the aforementioned operation, the left indicator light 67 begins to flash differently than in the waiting state. This flashing can, for example, be similar to when automatic braking intervenes, characterized by repeated illumination for a time interval of time T3 (e.g., 0.5 to 1 second) at intervals of time T4 (e.g., 0.5 to 1 second).

[0164] Here, the timing ta at which the left movable part 57 moves to the HIGH position and the left indicator light 67 begins to flash is set as follows: That is, the timing ta is preceded by a time td (e.g., approximately 1 second) by the timing tb at which the automatic steering intervention function begins to operate. In other words, the operation of the left movable part actuator 105L and the flashing of the left indicator light 67 begin before the operation of the automatic steering intervention function. Therefore, the driver can be notified in advance that the automatic steering intervention function is about to begin operating.

[0165] It should be noted that the operation of the left movable actuator 105L and the flashing of the left indicator light 67 stop simultaneously at the time when the automatic steering intervention function stops.

[0166] Figure 14This shows the state where the driving support device 70 activates the automatic steering intervention function from the waiting state, so that the driving path of the motorized two-wheeled vehicle 1 is oriented to the right.

[0167] For example, when the steering control unit 77 of the driving support device 70 determines that the motorized two-wheeled vehicle 1 is too close to the left side of the lane, it will make the motorized two-wheeled vehicle 1 return to the right side of its travel path.

[0168] At this time, the steering control unit 77 turns the front wheels 3 to the left via the steering actuator 74. That is, it turns the front wheels 3 to the opposite side of the side where the travel path of the motorized two-wheeled vehicle 1 is to be changed (reverse steering). As a result, the motorized two-wheeled vehicle 1 can be naturally turned in the direction of the change of travel path.

[0169] When the aforementioned automatic steering intervention function is in operation, only the right movable part 56 of the motorized two-wheeled vehicle 1, which changes the direction of travel (to the right), moves from the LOW position to the HIGH position. Additionally, the right indicator light 66 of the instrument panel 61 flashes in a different flashing pattern than in the waiting state.

[0170] Therefore, the driver can identify the following points through the tactile and visual senses of their legs clamping the vehicle body with their knees: that is, they can identify when the automatic steering intervention function is working and the direction the motorized two-wheeled vehicle 1 should be oriented.

[0171] By pressing the occupant's right leg outward (to the right) in the vehicle width direction using the right movable part 56, the right leg is opened outward (to the right). This allows the driver to more clearly recognize that the automatic steering intervention function to the right of the vehicle is in operation. In addition, by opening the right leg to the right, the driver's center of gravity shifts to the right relative to the vehicle body, allowing for a posture suitable for right turns.

[0172] Figure 15 Showing automatic steering intervention function Figure 14 The operating mode of the right movable actuator 105R and the left movable actuator 105L during operation is shown.

[0173] Automatic steering intervention function Figure 14 During operation, only the right movable part actuator 105R is activated, causing the right movable part 56 to move from the LOW position to the HIGH position.

[0174] Additionally, during the aforementioned operation, the right indicator light 66 begins to flash differently than in the waiting state. This flashing can be similar to, for example, when automatic braking intervenes, set to a pattern of repeated illumination for time T3 (e.g., 0.5 to 1 second) at intervals of time T4 (e.g., 0.5 to 1 second).

[0175] Here, the timing ta at which the right movable part 56 moves to the HIGH position and the right indicator light 66 begins to flash is set as follows: That is, the timing ta is preceded by a time td (e.g., approximately 1 second) by the timing tb at which the automatic steering intervention function begins to operate. In other words, the operation of the right movable part actuator 105R and the flashing of the right indicator light 66 begin before the operation of the automatic steering intervention function. Therefore, the driver can be notified in advance that the automatic steering intervention function is about to begin operating.

[0176] It should be noted that the operation of the right movable actuator 105R and the flashing of the right indicator light 66 stop simultaneously at the time when the automatic steering intervention function stops.

[0177] As explained above, the vehicle information notification device in the above embodiment has at least one of the left and right outer body portions 1L and 1R of the vehicle body 1A that supports the steering system component 10A to enable steering, and is operated by left and right movable part actuators 105L and 105R. The left and right movable parts 56 and 57 have left and right outer surfaces 56e and 57e located forward of the driver's seat 19 and above the footrest 25 where the driver places their feet, respectively, and capable of contacting the driver's legs. The left and right movable parts 56 and 57 cause the left and right outer surfaces 56e and 57e to operate in a predetermined manner, thereby notifying the driver of predetermined information.

[0178] According to this structure, at least one of the two outer body portions 1L and 1R on the left and right sides of the vehicle body 1A is provided with left and right movable parts 56 and 57. Through the operation of these left and right movable parts 56 and 57, predetermined information can be communicated to the driver's legs. The left and right movable parts 56 and 57 are separate from the steering system components 10A (particularly the handlebars 2). Thus, the notification of information based on the left and right movable parts 56 and 57 is separated from the steering operation, allowing the driver to easily receive the notification.

[0179] Furthermore, in the aforementioned vehicle information notification device, the left and right movable parts 56 and 57 operate in a manner that moves the left and right outer surfaces 56e and 57e outward in the vehicle width direction. This improves the reliability of contact with the driver's legs, allowing the driver to easily receive information notifications.

[0180] Furthermore, in the aforementioned vehicle information notification device, the left and right movable parts 56 and 57 are respectively provided on the left and right outer sides 1L and 1R of the vehicle body, and can operate independently on the left and right sides. This allows for the combination of different operating methods for the left and right movable parts 56 and 57. Consequently, more information can be notified to the driver, and the variety of information notified can be increased.

[0181] Furthermore, the information notification device for the aforementioned vehicle includes an operation intervention function that can intervene in the driver's actions, and the left and right movable parts 56 and 57 operate in conjunction with this operation intervention function. Thus, the operation of the operation intervention function can be communicated to the driver through the operation of the left and right movable parts 56 and 57.

[0182] Furthermore, in the aforementioned vehicle information notification device, when the operation intervention function is activated, the left and right movable parts 56 and 57 begin to operate at times ta and te, which are earlier than the start times tb and tf of the operation intervention function. This allows the driver to be notified in advance of the start of the operation intervention function.

[0183] Furthermore, the information notification device for the aforementioned vehicle includes at least one of a steering intervention function and a braking intervention function as the operation intervention function. Thus, by operating the left and right movable parts 56 and 57, the driver can be notified that at least one of the steering intervention function and the braking intervention function is in operation.

[0184] Furthermore, in the aforementioned vehicle information notification device, the movable parts 56 and 57 on both the left and right sides operate when the brake intervention function is activated. Thus, the operation of these movable parts allows the driver to be notified of the brake intervention function's operation. This improves the reliability of notifications regarding the brake intervention function's operation, which is prone to triggering driver reactions.

[0185] Furthermore, in the aforementioned vehicle information notification device, when the steering intervention function is activated, the movable parts 56 and 57 on the left and right sides are activated. Thus, by activating the movable parts 56 and 57 on the left and right sides, the driver can be notified of the steering intervention function's operation. That is, by which movable part 56 or 57 is activated, information including the steering direction based on the steering intervention function can be communicated to the driver.

[0186] Furthermore, in the aforementioned vehicle information notification device, the steering intervention function includes a route-changing function that allows the motorized two-wheeled vehicle 1 to change its travel path to either the left or right. When the steering intervention function is activated, the left and right movable parts 56 and 57 on the side that changes the travel path of the motorized two-wheeled vehicle 1 operate in such a way that the outer surfaces 56e and 57e move outward in the vehicle width direction. This allows the driver's leg on the route-changing side to open outward in the vehicle width direction, promoting a suitable steering posture.

[0187] Furthermore, in the aforementioned vehicle information notification device, during the waiting state before the operation intervention function is activated and engaged, the left and right movable parts 56 and 57 operate as follows: That is, the left and right movable parts 56 and 57 operate in a different manner than when the operation intervention function is actively engaged. This allows the driver to be notified that the operation intervention function is in a waiting state.

[0188] Furthermore, the vehicle information notification device described above also includes left and right display devices 66 and 67, which are linked to the operation of the left and right movable parts 56 and 57 and are used to display predetermined information to the driver. Thus, through the operation of the left and right movable parts 56 and 57 and the display of the left and right display devices 66 and 67, information notification to the driver can be delivered more reliably.

[0189] It should be noted that the present invention is not limited to the embodiments described above. For example, the driving support device 70 may have both steering intervention and braking intervention functions as its operation intervention functions, but it is not limited to this. That is, the driving support device 70 may also have only one of the steering intervention function and braking intervention function as its operation intervention function.

[0190] In this implementation, an example of notifying the operating information of a device related to driving assistance is shown, but the implementation is not limited to this. That is, the notification may also include information from a navigation system or an ITS (Intelligent Transport Systems).

[0191] The present invention is not limited to a structure having movable parts on both sides of the left and right outer sides of the vehicle body. That is, the present invention can also be a structure having a movable part only on one side of the left and right outer sides of the vehicle body.

[0192] The movable part can also be located at the position where it connects with the driver's lower leg or foot (e.g., a part of the outer side of the vehicle body that can be contacted by the calf, ankle, or sole of the foot (including the footrest)). The footrest is not limited to a rod type, but includes a base type and a plate type. The movable part can also be located in the seat that connects with the driver's buttocks or groin area, or in the lumbar support that connects with the waist. That is, the movable part only needs to form an outer surface that naturally connects with the driver's body (especially the lower body) in a normal riding posture.

[0193] The term "straddle-mounted vehicle" includes all vehicles in which the driver straddles the vehicle. That is, straddle-mounted vehicles include not only motorized two-wheeled vehicles (including bicycles and small motorcycles with a prime mover), but also three-wheeled (including vehicles with two wheels in the front and one in the back, as well as vehicles with two wheels in the front and one in the back) or four-wheeled vehicles. Additionally, it includes vehicles whose prime mover includes an electric motor.

[0194] Furthermore, the structure described above is an example of the present invention. That is, the constituent elements of the embodiment can be replaced with well-known constituent elements, and various modifications can be made without departing from the spirit of the present invention.
