[0019] Fig. 3 is an exploded perspective view of the turn signal switch unit 41 as viewed from above and in front. Fig. 4 is an exploded perspective view of the turn signal switch unit 41 as viewed from below and in rear. Fig. 5 is a vertical cross-sectional view of the turn signal switch unit 41 at the center in the left-right direction. The turn signal switch unit (turn signal device) 41 is housed and mounted in the handlebar switch 40. The turn signal switch unit 41 of this embodiment has a bottom case (first container) 50, a swing lever (operator) 60 having an elongated shape and swingably supported by the bottom case 50, a movable member 70 that moves in conjunction with the swing lever 60, and a top case (second container) 80 that covers the movable member 70.

[0020] In this embodiment, the shape of the turn signal switch unit 41 will be described based on the direction in which the rocking lever 60 shown in Figures 3 to 5 extends. That is, as shown in Figures 3 to 5, a case will be described in which the rocking lever 60 extends in the front-rear direction and is disposed so as to be perpendicular to the up-down and left-right directions. That is, in this embodiment, the front-rear, left-right, and up-down directions of the turn signal switch unit 41 will be described as being the same as the front-rear, left-right, and up-down directions of the vehicle body.

[0021] FIG. 6 is a view showing the relationship between the bottom case 50 and the swing lever 60 as viewed in the axial direction of the swing shaft 52. As shown in FIG. The bottom case 50 is formed in a block shape. The bottom case 50 has a rectangular plate-like base portion 51 having a thickness in the vertical direction. A swing shaft 52 extending upward from the upper surface of the base portion 51 is supported at the rear of the base portion 51. A guide wall (guide) 53 protruding upward from the upper surface of the base portion 51 is formed on the radially outer side of the swing shaft 52. The guide wall 53 in this embodiment is formed symmetrically. The guide wall 53 has a short operation guide surface (first inclined surface) 53a that inclines backward as it advances from the left-right center (corresponding to the axis L0 of the swing lever 60) to the outside in the left-right direction, and a long operation guide surface 53b (second inclined surface) that extends from the outer end of the short operation guide surface 53a in the left-right direction and inclines backward as it advances to the outside in the left-right direction. A boundary portion 53d is formed between the short operation guide surface 53a and the long operation guide surface 53b.

[0022] A rocking lever 60 is supported on the rocking shaft 52 so as to be able to rock. The rocking lever 60 extends in the front-rear direction. The rocking lever 60 is configured to be linearly symmetrical with respect to the front-rear direction. The rocking lever 60 has a lever main body 61 extending in the front-rear direction. A long hole 61a is formed in the lever main body 61, penetrating it in the up-down direction. The long hole 61a extends in the front-rear direction along the lever main body 61. The rocking shaft 52 is inserted into the long hole 61a. The lever body 61 is capable of swinging in the left-right direction around the swing shaft 52. In addition, the lever body 61 is capable of moving in the front-rear direction relative to the swing shaft 52 due to the front-rear length of the long hole 61a.

[0023] As shown in Fig. 6, the axis extending along the lever body 61 is indicated by axis L0, L1, or L2 according to the swing position. Therefore, hereinafter, the position in which the swing lever 60 is not operated, i.e., the initial position of the swing lever 60, is also referred to as the initial position L0 using the axis of the swing lever 60. Also, the position in which the swing lever 60 contacts both the short operation guide surface 53a and the long operation guide surface 53b, i.e., the position in which the axis passes through the boundary portion 53d, is also referred to as the changed position L1. Furthermore, the position in which the swing lever 60 abuts against the third surface 53c is also referred to as the limit position L2.

[0024] An operating part 62 operated by a driver (operator) is supported at the rear of the lever body 61. The operating part 62 is supported at the rear of the lever body 61 via a shaft part 63 extending in the front-rear direction. By operating the operating part 62, it becomes possible to swing the lever body 61 of the rocking lever 60 left and right and move it forward and backward.

[0025] 5, a sliding pin 64 extending along the lever body 61 is supported at the front portion of the lever body 61. The sliding pin 64 is supported so as to be movable forward and backward relative to the lever body 61.

[0026] Specifically, the lever body 61 has a mounting hole 61b extending rearward from its front end. A retaining portion 61c having a smaller diameter than the mounting hole 61b is formed at the front end of the mounting hole 61b. An inner peripheral opening 61d formed by the inner peripheral end of the retaining portion 61c allows communication between the inside and outside of the mounting hole 61b. The sliding pin 64 has a columnar body 64a that corresponds to the inner diameter of the inner peripheral opening 61d. A rounded sliding portion 64b is formed at the tip (front end) of the body 64a. A plurality of legs 64c extending rearward are formed at the rear end of the body 64a. The legs 64c are supported by the body 64a with intervals between them in the circumferential direction of the body 64a. A claw portion 64d protruding radially outward from the leg 64c is formed at the rear end of the leg 64c.

[0027] Here, a compression spring (biasing member) 65 is inserted into the mounting hole 61b. After the compression spring 65 is inserted, the sliding pin 64 is inserted into the mounting hole 61b. That is, the leg 64c is inserted into the mounting hole 61b from the inner circumferential opening 61d in a state in which the leg 64c is pushed into the radial center of the sliding pin 64 to reduce its diameter. As a result, the leg 64c compresses the compression spring 65 rearward and is biased forward by the compression spring 65, and the leg 64c returns to its original position radially outward, so that the claw 64d can be prevented from coming off by the retaining portion 61c of the mounting hole 61b. The sliding pin 64 is embedded in and protrudes from the mounting hole 61b, so that the sliding pin 64 can advance and retreat along the lever main body 61. The rocking lever 60 may be assembled by, for example, splitting it into left and right halves and assembling the left and right halves.

[0028] An upwardly protruding swing pin 66 is integrally provided on the front upper surface of the lever body 61. The lever body 61, the operating portion 62, the shaft portion 63, the sliding pin 64, the compression spring 65, and the swing pin 66 constitute the swing lever 60 of this embodiment.

[0029] The swing lever 60 is attached to the bottom case 50. That is, the sliding pin 64 is pressed into the lever main body 61, and is attached to the swing shaft 52 with the sliding pin 64 facing the guide wall 53. At this time, the spring force of the compression spring 65 urges the sliding pin 64 toward the guide wall 53 and presses the guide wall 53, so that the lever main body 61 is pushed backward as a reaction force. The lever main body 61 pushed backward is held in a state where the swing shaft 52 abuts against the inner peripheral surface at the front end of the long hole 61a.

[0030] When the rocking lever 60 is rocked from the initial position L0 (dashed line in FIG. 6) to the right limit position L2 (double-dashed line in FIG. 6), the sliding pin 64 slides in the order of the short operation guide surface 53a, the boundary portion 53d, and the long operation guide surface 53b while pressing the short operation guide surface 53a and the long operation guide surface 53b. That is, the rocking lever 60 passes through the change position L1 (broken line in FIG. 6). Then, when the rocking lever 60 abuts against the third surface 53c of the guide wall 53 and moves to the limit position L2, the rocking outward in the left-right direction is restricted.

[0031] In addition, when the rocking lever 60 is pushed forward against the force of the compression spring 54, the sliding pin 64 sinks into the long hole 51b, and the rocking shaft 52 moves relatively backward within the long hole 61a, causing the entire rocking lever 60 to move forward (dotted line in Figure 6).

[0032] Therefore, the swing pin 66 on the upper surface of the lever body 61 swings left and right and moves back and forth as the swing lever 60 moves.

[0033] Here, if the inclination angles of the operation guide surfaces 53a and 53b are defined as the angles between the lines M1 and M2 perpendicular to the longitudinal direction of the rocking lever 60 at the initial position L0, i.e., the axis L0, and the outer surfaces (rear surfaces) of the operation guide surfaces 53a and 53b, respectively, the inclination angle θ2 of the long operation guide surface 53b is configured to be larger than the inclination angle θ1 of the short operation guide surface 53a. In other words, the inclination angle θ2 of the long operation guide surface 53b is configured to be steeper than the inclination angle θ1 of the short operation guide surface 53a. As a result, when the sliding pin 64 moves from one of the short operation guide surface 53a and the long operation guide surface 53b to the other, a large change can be easily caused in the compression spring 65, etc., and a large amount of change can be caused compared to when the sliding pin 64 moves while abutting only against either the short operation guide surface 53a or the long operation guide surface 53b. Therefore, it is possible to easily make the driver feel a change in the operation feeling.

[0034] In addition, the angle φ1 between the short operation guide surface 53a and the axis L1 at the left-right outer end portion of the short operation guide surface 53a, and the angle φ2 between the long operation guide surface 53b and the axis L2 at the left-right outer end portion of the long operation guide surface 53b are each configured to be greater than 90 degrees. This makes it possible to apply a reaction force to the rocking lever 60 that returns the rocking lever 60 to the initial position L0 by utilizing the biasing force of the compression spring 65 in the axial direction of the rocking lever 60. Note that in FIG. 6, angles θ1, θ2, φ1, and φ2 are illustrated only when the operating part 62 of the rocking lever 60 is moved to the left, but since the present embodiment is symmetrical, the angles on the left side when the operating part 62 of the rocking lever 60 is moved to the right are also the same in magnitude as the angles θ1, θ2, φ1, and φ2 on the right side.

[0035] 7 is a view seen in the axial direction of the swing shaft 52, showing the relationship between the swing pin 66 of the swing lever 60, the movable member 70, and the top case 80. In FIG. 7, only a part of the top case 80 is shown. As shown in Figs. 3 to 5 and 7, a movable member 70 engages with the swing pin 66. The movable member 70 has a substantially plate-shaped base portion 71 having a thickness in the up-down direction. A pressed portion 72 that protrudes toward the bottom case 50 is formed on the lower surface of the base portion 71. The pressed portion 72 is formed in a wall shape so as to surround the front side of the swing pin 66. The pressed portion 72 is pressed by the swing pin 66 of the swing lever 60 when the swing lever 60 moves from the initial position L0.

[0036] The pressed portion 72 in this embodiment is symmetrical. The pressed portion 72 has a first surface 72a that extends from a position away from the axis L0 indicating the left-right center and inclines rearward as it progresses outward in the left-right direction, and a second surface 72b that extends rearward from the outer left-right end of the first surface 72a. Recesses 72c that are recessed forward are formed at the inner left-right ends of the left and right first surfaces 72a. The recesses 72c are formed symmetrically with respect to the axis L0 indicating the left-right center. The recesses 72c have a left-right width that allows the swing pin 66 to enter.

[0037] A protruding rib 74 that protrudes upward is formed at the front end of the movable member 70. The protruding rib 74 is plate-shaped and extends in the left-right direction. The protruding rib 74 engages with a groove 81a (see FIG. 5) of the top case 80 above. The groove 81a is recessed upward, has a front-to-rear width, and extends in the left-right direction. By engaging the protruding rib 74 with the groove 81a, the movable member 70 is movable in the left-right direction as well as in the front-to-rear direction. The front-to-rear width of the groove 81a is slightly larger than the thickness of the protruding rib 74.

[0038] A movable contact 75 protruding forward is provided on the front surface of the movable member 70. In the present embodiment, a pair of movable contacts 75 are provided on the left and right. The movable contacts 75 are electrically connected to each other inside the movable member 70.

[0039] As shown in FIG. 5, a mounting hole 71a is formed at the rear end of the base portion 71, which is hollowed out in a cylindrical shape toward the front. A movable spring (second biasing member) 77 extending in the front-rear direction is mounted in the mounting hole 71a. A semispherical sliding body 78 is supported at the rear end of the movable spring 77. The sliding body 78 in this embodiment has a diameter smaller than the diameter of the mounting hole 71a and is configured to be able to enter the mounting hole 71a. The sliding body 78 abuts against the rear wall 83 of the top case 80 when the movable spring 77 is in a compressed state. As a result, when the movable member 70 moves in the left-right direction, the movable member 70 is able to move in the left-right direction while being biased forward by the spring force of the movable spring 77.

[0040] The top case 80 is disposed above the movable member 70. The top case 80 is fixed to the bottom case 50 by a fixing device (not shown). As a result, the rocking lever 60 and the movable member 70 are housed in the bottom case 50 and the top case 80.

[0041] The top case 80 has a rectangular plate-like base portion 81 having a thickness in the up-down direction. The base portion 81 is formed with a front wall 82, a rear wall 83, a left wall 84, and a right wall 85 (see FIG. 4) on the front, rear, left, and right sides that protrude toward the bottom case 50. The base portion 81, the front wall 82, the rear wall 83, the left wall 84, and the right wall 85 form an accommodation space 80a (see FIG. 4 and FIG. 5) that is recessed upward.

[0042] A fixed contact 87 protruding rearward is provided on the front wall 82. A plurality of fixed contacts 87 are provided. In this embodiment, three fixed contacts 87 are provided. The fixed contacts 87 are arranged symmetrically about the left-right center. The three fixed contacts 87 are arranged at equal intervals in the left-right direction. The fixed contacts 87 are arranged at the same interval as the interval between the pair of movable contacts 75. The fixed contacts 87 are arranged so that the movable contacts 75 of the movable member 70 can come into contact with them. The pair of movable contacts 75 come into contact with an adjacent set of fixed contacts 87 simultaneously or approximately simultaneously. Wires (not shown) extend from the outside of the winker switch unit 41 to each of the fixed contacts 87. In this embodiment, three wires extend.

[0043] 7, a guide surface 88 having an uneven shape in a plan view is provided on the front surface of the rear wall 83. The guide surface 88 has a central portion 88a that extends in the left-right direction and curves to be concave rearward, peaks 88b that are connected to both left and right ends of the central portion 88a and protrude forward, valleys 88c that are connected to the left-right outer ends of the peaks 88b and are concave rearward relative to the peaks 88b, and an extension portion 88d that is connected to the left-right outer ends of the valleys 88c and extends in the left-right direction.

[0044] The central portion 88a is provided on the left-right center. The peak portion 88b is formed according to a contact start position (broken line in FIG. 7) where the movable contact 75 starts to contact the fixed contact 87 when the movable member 70 moves outward in the left-right direction from the initial position L0. That is, the peak portion 88b is formed at a position where the sliding body 78 moves when the movable member 70 moves to the contact start position.

[0045] Here, the sliding body 78 at the rear of the movable member 70 is in slidable contact with the guide surface 88. Therefore, due to the uneven shape of the guide surface 88, the compression amount of the movable spring 77 differs depending on the left and right movement positions, and the force with which the movable member 70 is urged forward differs depending on the left and right movement positions.

[0046] The sliding body 78 comes into contact with the center portion 88a when the rocking lever 60 moves to the initial position L0. When the movable member 70 moves to the contact start position, the movable spring 77 is further compressed by the peak portion 88b via the sliding body 78, and a larger forward biasing force acts on the movable member 70. Therefore, when the movable contact 75 approaches the fixed contact 87, the movable contact 75 tends to approach the fixed contact 87 quickly, and the generation of sparks is suppressed.

[0047] When the movable member 70 passes the contact start position to the outside in the left-right direction and the sliding body 78 passes over the peak portion 88b, the sliding body 78 moves to the valley portion 88c, so that the movable spring 77 is elastically restored and the moving position of the movable member 70 is maintained. At this time, a change in the operational movement resistance occurs in the movable member 70, and so-called a clicking sensation is obtained.

[0048] In this embodiment, when a pair of adjacent fixed contacts 87 on the right side are energized, it is processed as a left turn signal input. When a pair of adjacent fixed contacts 87 on the left side are energized, it is processed as a right turn signal input. When none of the fixed contacts 87 are energized, it is processed as a cancel input.

[0049] 6 and 7, when the rocking lever 60 is held in the initial position L0, for example, when the operating part 62 at the rear end of the rocking lever 60 is operated to the left, the rocking lever 60 rotates about the rocking shaft 52 and the front sliding pin 64 moves to the right. At this time, since the sliding pin 64 is biased against the front guide wall 53 by the compression spring 65, the sliding pin 64 moves to the right while abutting against the guide wall 53. Therefore, the driver operates the rocking lever 60 while receiving a reaction force according to the amount of compression of the compression spring 65 due to the inclined shape of the guide wall 53, etc.

[0050] Furthermore, when the operation part 62 is operated to the left for a so-called long operation, the front sliding pin 64 moves further to the right and passes through the boundary part 53d between the short operation guide surface 53a and the long operation guide surface 53b, and passes through the change position L1 (broken line in FIG. 6). At this time, the inclination angles θ1 and θ2 of the short operation guide surface 53a and the long operation guide surface 53b are significantly different, and the driver moves the sliding pin 64 while feeling a large change in the operating force due to the relationship between the short operation guide surface 53a, the long operation guide surface 53b, and the compression spring 65.

[0051] When the operating portion 62 is further operated to the left, the rocking lever 60 reaches the limit position L2 on the right side, and the rocking of the rocking lever 60 is restricted.

[0052] In this embodiment, since the left-right direction is symmetrical, the operation unit 62 is moved to the right in the same manner as the operation unit 62 is moved to the left.

[0053] Furthermore, when the driver releases the operating portion 62 while performing the short or long operation of the rocking lever 60, a forward biasing force along the axis L0-L2 direction acts on the sliding pin 64, so that a force acts on the sliding pin 64 to return it to the initial position L0 according to the inclined shape of the guide wall 53. Therefore, the rocking lever 60 tries to return to the initial position L0.

[0054] Furthermore, when the operating part 62 is pushed forward, the swing shaft 52 of the swing lever 60 moves relatively backward in the long hole 61a, and the swing lever 60 moves forward. At this time, the sliding pin 64 is pressed by the guide wall 53 of the bottom case 50, compressing the compression spring 65. Therefore, when the operating part 62 is released, the compression spring 65 returns to its original position, and the swing lever 60 returns to its original position.

[0055] Here, the swing lever 60 is provided with a swing pin 66. Therefore, the swing pin 66 swings left and right together with the swing lever 60 and moves forward in response to the movement of the swing lever 60.

[0056] That is, when the rocking lever 60 is moved to the initial position L0 (solid line in FIG. 6), the rocking pin 66 is held at the initial position L0 (solid line in FIG. 7). Here, when the operating part 62 of the rocking lever 60 is moved to the left, the rocking pin 66 moves to the right around the rocking shaft 52. At this time, the rocking pin 66 abuts against the inclined first surface 72a of the pressed part 72 of the movable member 70, and the pressed part 72 is pushed by the rocking pin 66 and moves to the right together with the rocking pin 66. Therefore, the movable member 70 moves to the right, and the movable contact 75 at the front end of the movable member 70 abuts against a pair of adjacent fixed contacts 87 on the right side (broken line in FIG. 7). That is, the fixed contacts 87 are energized.

[0057] Furthermore, when the operating portion 62 of the rocking lever 60 is moved to the left and the rocking pin 66 is moved to the right, the rocking pin 66 moves to the limit position L2 (dotted line in FIG. 7). In this embodiment, when the rocking lever 60 is located between the contact start position (dashed line in FIG. 7) and the limit position L2 (dashed line in FIG. 8), the movable contact 75 is configured to be maintained in contact with the fixed contact 87. That is, the pair of adjacent fixed contacts 87 on the right side continues to be energized.

[0058] Fig. 8 is a view different from Fig. 7 as viewed in the axial direction of the swing shaft 52, showing the relationship between the swing pin 66 of the swing lever 60, the movable member 70, and the top case 80. In Fig. 8, only a part of the top case 80 is shown. In this embodiment, when the movable contact 75 passes the contact start position (broken line in FIG. 7), the sliding body 78 at the rear end of the movable member 70 climbs over the peak portion 88b of the guide surface 88 and moves to the valley portion 88c. Therefore, the movable member 70 is held at the position of the valley portion 88c by the movable spring 77 and the sliding body 78.

[0059] At this time, when the driver releases the operating portion 62, the rocking lever 60 tries to return to the initial position L0 due to the action of the sliding pin 64 and the guide wall 53. Therefore, the rocking pin 66 moves leftward from the limit position L2 and comes into contact with the pressed portion 72 of the movable member 70 held by the valley portion 88c (dotted line in FIG. 8). Therefore, the movable member 70 maintains the state in which the rocking pin 66 tries to return to the initial position L0 (dotted line in FIG. 8).

[0060] In this state, when the operating portion 62 is pushed forward, the rocking pin 66 moves axially forward together with the rocking lever 60. Therefore, the rocking pin 66 presses the pressed portion 72, and the movable member 70 receives a left-right force due to the inclined shape of the pressed portion 72, returning to the initial position L0. Therefore, a force acts on the movable member 70, which makes the sliding body 78 overcome the peak portion 88b while resisting the spring force of the movable spring 77. When the rocking pin 66 moves further forward and enters the recess 75c of the pressed portion 72, a force acts on the movable member 70, which makes the sliding body 78 overcome the peak portion 88b, and the movable member 70 returns to the initial position L0. At this time, the pair of movable contacts 75 are separated from the fixed contact 87, so that the fixed contact 87 is not energized, resulting in a cancel input. In this embodiment, the swing pin 66 attempting to return to the initial position L0 abuts against the pressed portion 72 of the movable member 70 held in the valley portion 88c, but the pressed portion 72 may be formed so as not to abut against it.

[0061] In this embodiment, the rocking lever 60 and the bottom case 50 are configured so that when the rocking lever 60 is operated in a normal operation manner from the initial position L0 toward the limit position L2, a predetermined time elapses from the contact start position (broken line in FIG. 7) where the movable contact 75 starts to contact the fixed contact 87 until the rocking lever 60 reaches the change position L1 (broken line in FIG. 6). Specifically, the size of the guide wall 53, the elastic force of the compression spring 65, the size of the rocking lever 60, and the like are configured so that a predetermined time elapses. In other words, the rocking lever 60 is configured so that it passes through the change position L1 by operating the operating part 62 for a predetermined time. Therefore, it can be said that when the normal operation is performed for a predetermined time, the driver can feel a large change in the operating force caused by the relationship between the sliding pin 64, the short operation guide surface 53a, the long operation guide surface 53b, and the compression spring 65. In this embodiment, the predetermined time is 0.1 seconds.

[0062] FIG. 9 is a block diagram showing the overall configuration of the turn signal flashing system 200. As shown in FIG. The saddle-ride type vehicle 10 includes a turn signal flashing system 200. The turn signal flashing system 200 includes a control unit 100. The control unit 100 is a computer device including an ECU (Electronic Control Unit) and the like. The control unit 100 includes a processor such as a CPU (Central Processing Unit) and a memory such as a ROM (Read Only Memory) and a RAM (Random access memory). The memory stores a control program executed by the processor. The memory also stores data processed by the processor when the processor executes the control program and data of the processing results. The processor executes the computer program stored in the memory to realize various functional configurations of the control unit 100.

[0063] The control unit 100 is electrically connected to signal input elements such as a wheel speed sensor 111, an IMU 112, and a turn signal switch unit 41. The electrical signals output from the signal input elements 111, 112, and 141 are input to the control unit 100.

[0064] The wheel speed sensor 111 detects the vehicle body speed of the saddle type vehicle 10 , that is, the traveling speed, based on the rotation speed of the front wheel 13 .

[0065] An IMU (Inertial Measurement Unit) 112 is provided on the body frame 11, and detects the longitudinal acceleration, lateral acceleration, roll angle (bank angle), and the like of the saddle-ride type vehicle 10.

[0066] When the fixed contact 87 and the movable contact 75 of the winker switch unit 41 come into contact with each other, a current corresponding to the contacted fixed contact 87 is input to the control unit 100 .

[0067] The control unit 100 is electrically connected to a front drive unit 121 and a rear drive unit 122 as signal output elements.

[0068] The front drive unit 121 drives the pair of left and right front blinkers 32 to blink. The front drive unit 121 blinks the pair of left and right front blinkers 32 under the control of the control unit 100. In Fig. 9, the left front blinker 32 is shown as a left front blinker 32L, and the right front blinker 32 is shown as a right front blinker 32R.

[0069] The rear drive unit 122 drives the pair of left and right rear blinkers 35 to blink. The rear drive unit 122 blinks the pair of left and right rear blinkers 35 under the control of the control unit 100. In Fig. 9, the left rear blinker 35 is shown as a left rear blinker 35L, and the right rear blinker 35 is shown as a right rear blinker 35R.

[0070] FIG. 10 is a flowchart showing an example of the blinker blinking process. The control unit 100 of this embodiment executes a turn signal blinking process for blinking the front turn signals 32 and the rear turn signals 35 based on the energization of the turn signal switch unit 41 . The control unit 100 repeatedly executes the process shown in FIG. 10 at a predetermined cycle while the main switch is ON.

[0071] In step ST11, the control unit 100 determines whether or not there is a left winker input. Specifically, the control unit 100 determines whether or not the movable contact 75 and the pair of adjacent fixed contacts 87 on the right side are energized based on an energization input from the winker switch unit 41. When the control unit 100 determines that there is a left turn signal input (step ST11; YES), the control unit 100 advances the process to step ST12. When the control unit 100 does not determine that there is a left turn signal input, that is, when it determines that there is no left turn signal input (step ST11; NO), the control unit 100 advances the process to step ST21.

[0072] In step ST12, the control unit 100 starts measuring the energization time of the left winker input.

[0073] In step ST13, the control unit 100 determines whether the current-flow time is equal to or less than a threshold value. Specifically, the threshold value is set to 0.1 seconds, for example. Therefore, the control unit 100 determines whether the current-flow time is equal to or less than 0.1 seconds. When the control unit 100 determines that the current application time is equal to or shorter than the threshold value (step ST13; YES), the control unit 100 advances the process to step ST14. When the control unit 100 determines that the current application time is greater than the threshold value (step ST13; NO), the control unit 100 advances the process to step ST15.

[0074] In step ST14, the control unit 100 causes the left front blinker 32L and the rear blinker 35L to blink a predetermined number of times. In this embodiment, the control unit 100 causes the left front blinker 32L and the rear blinker 35L to blink a predetermined number of times so that they blink at a constant cycle of 60 to 120 times per minute. In this embodiment, the predetermined number of times is 3 times, but any number of times between 1 and 10 times is possible. After executing the process of step ST14, the control unit 100 ends the blinker blinking process.

[0075] In step ST15, the control unit 100 determines whether the traveling speed is equal to or greater than a predetermined speed. Specifically, the control unit 100 acquires the traveling speed based on the detection value of the wheel speed sensor 111. Then, the control unit 100 determines whether the traveling speed is equal to or greater than a predetermined speed based on the traveling speed. An example of the predetermined speed is 50 km / h. That is, the control unit 100 determines whether the traveling speed is equal to or greater than 50 km / h. In this way, it is determined whether the saddle type vehicle 10 is traveling at high speed.

[0076] When the control unit 100 determines that the traveling speed is equal to or higher than a predetermined speed (step ST15; YES), the process proceeds to step ST14. That is, when the saddle type vehicle 10 is traveling at high speed, it is assumed that the operation is for changing lanes, so the process proceeds to step ST14 in which the predetermined number of flashes are performed. This makes it possible to prevent erroneous operation even if the driver mistakenly performs a long operation at high speed. When the control unit 100 determines that the traveling speed is lower than the predetermined speed (step ST15; NO), the control unit 100 advances the process to step ST16.

[0077] In step ST16, the control unit 100 determines whether the roll angle to the left is equal to or smaller than a predetermined threshold. Specifically, the control unit 100 detects the roll angle of the saddle type vehicle 10 based on the detection value of the IMU 112, and determines whether the roll angle is equal to or smaller than a predetermined threshold. The threshold is, for example, 5 degrees. In this way, it is determined whether the saddle type vehicle 10 is banking.

[0078] When the control unit 100 determines that the roll angle is equal to or greater than the predetermined threshold value (step ST16; YES), the control unit 100 advances the process to step ST17. When the control unit 100 determines that the roll angle is less than the predetermined threshold value (step ST16; NO), the control unit 100 advances the process to step ST14. That is, when the roll angle of the saddle type vehicle 10 is small, it is assumed that the operation is a lane change, and the process advances to step ST14 in which the predetermined number of flashes are executed. This makes it possible to prevent erroneous operation even if the driver mistakenly performs a long operation while traveling approximately straight.

[0079] In step ST17, the control unit 100 starts continuous blinking of the left front blinker 32 and the left rear blinker 35. In this embodiment, the control unit 100 starts blinking of the left front blinker 32 and the left rear blinker 35 at a constant cycle of 60 to 120 times per minute.

[0080] In step ST18, the control unit 100 determines whether or not a cancel input has been made. Specifically, the control unit 100 determines whether or not a cancel input has been made based on whether or not the movable contact 75 has separated from the fixed contact 87. When the control section 100 determines that a cancel input has been made (step ST18; YES), the control section 100 advances the process to step ST19. When the control unit 100 determines that there is no cancel input (step ST18; NO), it repeats the process of step ST18.

[0081] In step ST19, the control unit 100 ends the continuous blinking of the left front blinker 32 and the left rear blinker 35, and ends the blinker blinking process.

[0082] In step ST21, the control unit 100 determines whether or not there is a right winker input. Specifically, the control unit 100 determines whether or not a pair of adjacent fixed contacts 87 on the left side are energized. When the control unit 100 determines that there is a right blinker input (step ST21; YES), the control unit 100 advances the process to step ST22. When the control unit 100 does not determine that there is a right turn signal input, that is, when it determines that there is no right turn signal input (step ST21; NO), the control unit 100 returns the process to step ST11.

[0083] Steps ST22 to ST29 are the same as steps ST12 to ST19, except that the target is the right side instead of the left side, and therefore the description thereof will be omitted.

[0084] In the saddle-ride type vehicle (vehicle) 10 of this embodiment, the blinking method of the turn signals 32, 35 is changed based on the energization time of the turn signal switch unit 41, so that the number of fixed contacts can be reduced and the configuration can be simplified compared to the case where a fixed contact is provided for each blinking method of the turn signals 32, 35. On the other hand, when the blinking method is switched depending on the energization time, even if a short operation is desired, it is possible that the driver may perform a long operation due to an erroneous operation, resulting in a long energization time. However, in a situation where the saddle-ride type vehicle 10 is not expected to turn, such as at high speed or when banking, only a predetermined number of blinks are executed instead of continuous blinking. This makes it possible to suppress the blinking of the turn signals from continuing due to the driver forgetting to input a cancel command.

[0085] In particular, the turn signal switch unit 41 includes a bottom case 50 and a swing lever 60. Therefore, for example, when the driver moves the operation part 62 to the left, by providing a boundary part 53d with the operation guide surfaces 53a, 53b at a position where it is assumed that a predetermined time has elapsed since the operation part 62 is turned on, the reaction force is reduced when the driver attempts a short operation, and is increased when the driver attempts a long operation, thereby making it easier for the driver to feel the change in the operation force. Therefore, the simple structure can inform the driver that the flashing method is being changed.

[0086] As described above, according to the first embodiment to which the present invention is applied, the turn signal switch unit 41 has a movable contact 75, a fixed contact 87, and a rocking lever 60, and the movable contact 75 moves in response to operation of the rocking lever 60. The movable contact 75 and the fixed contact 87 come into contact to pass electricity, causing the turn signals 32, 35 to flash. The turn signal switch unit 41 is configured to be able to flash the turn signals 32, 35 using a plurality of flashing methods, and the flashing method of the turn signals 32, 35 is changed depending on the electricity-passing time during which the movable contact 75 and the fixed contact 87 are in contact. According to this configuration, the blinking method of the turn signals 32, 35 can be changed according to the energization time of the contacts, so that the blinking method of the turn signals 32, 35 can be changed even if there is no change in the energization state of one fixed contact 87. Therefore, in the turn signal switch unit 41, it is easy to prevent the number of parts from increasing and the structure from becoming complicated, and it is possible to change the blinking method of the turn signals 32, 35 while maintaining a simple configuration. Therefore, it is easy to reduce the number of parts of the turn signal switch unit 41, leading to cost reduction.

[0087] In this embodiment, a compression spring 65 is provided that applies a reaction force to the rocking lever 60 so that the rocking lever 60 that has moved from the initial position L0 returns to the initial position L0, and the amount of change in the reaction force changes at a predetermined position. Specifically, in this embodiment, when the rocking lever 60 is moved from the initial position L0, when the rocking lever 60 passes through a predetermined change position L1 to which the rocking lever 60 moves after passing through a contact start position where the movable contact 75 and the fixed contact 87 start to come into contact, the amount of change in the reaction force changes greatly compared to when the rocking lever 60 is located between the contact start position and the change position L1. According to this configuration, if the power supply time for switching the flashing mode of the turn signals 32, 35 elapses when the rocking lever 60 is moved from the contact start position to the change position L1, the driver can easily understand that the flashing mode of the turn signals 32, 35 is being changed by the change in the operating force of the rocking lever 60.

[0088] In addition, this embodiment has a rocking lever 60 having a longitudinal shape, and a guide wall 53 that is provided in the movable range of the rocking lever 60 and guides the rocking lever 60, and the guide wall 53 has operation guide surfaces 53a, 53b with which the rocking lever 60 comes into contact, and the operation guide surfaces 53a, 53b have different inclination angles θ1, θ2, which are angles relative to a perpendicular direction perpendicular to the longitudinal direction of the rocking lever 60 in the initial position L0. According to this configuration, the rocking lever 60 moves while being in contact with the operation guide surfaces 53a, 53b having different inclination angles θ1, θ2, thereby changing the reaction force acting on the rocking lever 60. Therefore, by switching the blinking mode of the turn signals 32, 35 between the operation guide surfaces 53a, 53b having different inclination angles θ1, θ2, it is possible to make it easy for the operator to switch the blinking mode of the turn signals 32, 35.

[0089] In addition, in this embodiment, the inclination angle θ2 of the long operation guide surface 53b that the rocking lever 60 contacts when it passes through the change position L1 is larger than the inclination angle θ1 of the short operation guide surface 53a that the rocking lever 60 contacts when it passes through the contact start position, and the multiple flashing modes include a predetermined number of flashing mode in which the turn signals 32, 35 are flashed a predetermined number of times, and a continuous flashing mode in which the turn signals 32, 35 continue to flash, and when the inclination angle of the inclined surface that the rocking lever 60 contacts is larger than the short operation guide surface 53a that the rocking lever 60 contacts when it passes through the contact start position, the flashing of the turn signals 32, 35 becomes the continuous flashing mode. According to this configuration, the greater the inclination angle of the inclined surface with which the rocking lever 60 comes into contact, the greater the reaction force acting on the rocking lever 60, so that the operation does not require force up to the predetermined number of flashes mode, and requires force up to the continuous flashing mode, making it easier for the operator to understand how to input the flashing mode. In this case, when the control unit 100 of this embodiment flashes the turn signals 32, 35, if the power-on time does not exceed a predetermined time that is assumed to be required for the rocking lever 60 to move from the contact start position to the change position L1, it flashes the turn signals 32, 35 using the predetermined number of flashes mode, and if the power-on time exceeds the predetermined time, it flashes the turn signals 32, 35 using the continuous flashing mode.

[0090] Also, in this embodiment, the turn signal switch unit 41 is provided on the saddle-ride type vehicle 10, and the multiple blinking methods include a predetermined number of blinking method in which the turn signals 32, 35 are blinked a predetermined number of times, and a continuous blinking method in which the turn signals are continued to blink, and when the saddle-ride type vehicle 10 is traveling at or above a predetermined speed, the turn signals 32, 35 are blinked only using the predetermined number of blinking method. According to this configuration, it is possible to set an appropriate blinking method according to the speed. In this embodiment, when the vehicle is traveling at high speeds where right and left turns are not expected, specifically when the vehicle is traveling at a speed of 50 km / h or more, the blinking method is set to the predetermined number of times only, thereby preventing the blinking method from being changed to the continuous blinking method and suppressing erroneous operation by the operator.

[0091] In addition, in this embodiment, the device includes a rocking lever 60 having a longitudinal shape that is supported so as to be rockable, a guide wall 53 that is provided in the movable range of the rocking lever 60 and guides the rocking lever 60, and a compression spring 65 that urges the rocking lever 60 toward the guide wall 53 so as to abut the rocking lever 60 against the guide wall 53. The guide wall 53 has operation guide surfaces 53a, 53b with which the rocking lever 60 comes into contact, and the operation guide surfaces 53a, 53b have different inclination angles θ1, θ2, which are angles with respect to an orthogonal direction perpendicular to the longitudinal direction of the rocking lever 60 in the initial position L0. When the rocking lever 60 is moved from the initial position L0, when the rocking lever 60 passes through a predetermined change position L1 to which it moves after passing through a contact start position where the movable contact 75 and the fixed contact 87 begin to come into contact, the rocking lever 60 comes into contact with the long operation guide surface 53b having an inclination angle θ2 different from the short operation guide surface 53a with which it comes into contact at the contact start position. According to this configuration, when the rocking lever 60 is moved from the contact start position to the change position L1, if the power supply time for switching the flashing mode of the turn signals 32, 35 elapses, the amount of change in the operating force of the rocking lever 60 changes significantly, making it easy for the driver to understand that the flashing mode of the turn signals 32, 35 is being changed.

[0092] [Second embodiment] A second embodiment to which the present invention is applied will be described below. In this second embodiment, parts configured similarly to the first embodiment are given the same reference numerals and descriptions thereof will be omitted.

[0093] FIG. 11 is a diagram of a winker switch unit 241 according to the second embodiment of the present invention. A winker switch unit 241 according to the second embodiment includes a movable member 270 and a top case 280 according to the second embodiment, instead of the movable member 70 and the top case 80 according to the first embodiment. The movable member 270 and the top case 280 differ from the first embodiment in that the movable member 270 has one movable contact 275 and a fixed contact 287 of the top case 280 is provided in correspondence with the one movable contact 275.

[0094] Specifically, one movable contact 275 is provided at the center of the left and right on the front surface of the movable member 270 according to the second embodiment. A wire (not shown) extending from the outside of the turn signal switch unit 241 is connected to the movable contact 275.

[0095] In the top case 280 according to the second embodiment, fixed contacts 287 are provided at positions to which the movable contacts 275 move before the swing pin 66 passes through the change position L1 in response to the swing movement. The fixed contacts 287 are provided symmetrically about the left-right center. A total of two fixed contacts 287 are provided. Wires (not shown) extend from the fixed contacts 287. In the present embodiment, two wires are provided.

[0096] In the second embodiment, the number of movable contacts 275 and fixed contacts 287 differs from that in the first embodiment. However, like the first embodiment, the blinking mode of the turn signals 32, 35 is changed based on the power-on time of the turn signal switch unit 241. This makes it easier to reduce the number of fixed contacts and simplify the configuration compared to the case where a fixed contact is provided for each blinking mode of the turn signals 32, 35.

[0097] [Third embodiment] A third embodiment to which the present invention is applied will be described below. In this third embodiment, parts configured in the same manner as in the first or second embodiment will be given the same reference numerals and descriptions thereof will be omitted.

[0098] FIG. 12 is a diagram of a winker switch unit 341 according to a third embodiment of the present invention. A winker switch unit 341 according to the third embodiment differs from the first embodiment in that it has a bottom case 350 according to the second embodiment instead of the bottom case 50 according to the first embodiment.

[0099] Specifically, in the bottom case 350 according to the third embodiment, the guide wall 353 has an operation guide surface 353a that is an extension of the short operation guide surface 53a of the first embodiment. In other words, the long operation guide surface 53b of the first embodiment is omitted from the guide wall 353. A damper spring (third biasing member) 301 is disposed at the outer end in the left-right direction of the operation guide surface 353a. The damper spring 301 extends along the operation guide surface 353a. The damper spring 301 is attached to a mounting portion 353b that is recessed outward in the left-right direction from the third surface 353c. The damper spring 301 contacts the swing lever 60 at a position corresponding to the boundary portion 53d. When the swing lever 60 passes through the change position L1 and is further swung, the damper spring 301 is compressed. Therefore, the elastic force of the damper spring 301 is applied to the rocking lever 60, and the rocking lever 60 is biased toward the initial position L0.

[0100] In the third embodiment, for example, when the driver moves the operation unit 62 to the left, by disposing the damper spring 301 at a position where it is assumed that a predetermined time has elapsed since the operation is started, it is possible to easily give the driver a change in the operating force when the driver tries to perform a long operation. Therefore, it is possible to notify the driver that the flashing method is to be changed with a simple structure.

[0101] [Other embodiments] The above-described embodiment merely shows one aspect of the present invention, and any modification and application can be made without departing from the spirit and scope of the present invention.

[0102] In the above embodiment, the control unit 100 blinks the front blinkers 32 and the rear blinkers 35 based on the energized state of the blinker switch unit 41. However, the present invention is not limited to this. For example, the relay circuit may blink the front blinkers 32 and the rear blinkers 35 by inputting various electrical states of the blinker switch unit 41, the wheel speed sensor 111, etc. to the relay circuit.

[0103] In the above embodiment, the guide wall 53 of the bottom case 50 has the planar short operation guide surface 53a and the planar long operation guide surface 53b formed thereon, but the operation guide surfaces 53a and 53b may be curved surfaces. That is, the position where the curved short operation guide surface 53a and the curved long operation guide surface 53b are connected may form a bent boundary portion.

[0104] In the above embodiment, a motorcycle having a front wheel 13 and a rear wheel 15 has been used as an example of saddle-ride vehicle 10, but the present invention is not limited to this, and the present invention can be applied to a three-wheel saddle-ride vehicle having two front or two rear wheels, or a saddle-ride vehicle having four or more wheels.

[0105] [Configuration supported by the above embodiment] The above embodiment supports the following configurations.

[0106] (Configuration 1) A turn signal device having a movable contact, a fixed contact, and an operator, the movable contact moving in response to operation of the operator, and causing a turn signal to flash when the movable contact and the fixed contact come together to pass electricity, the turn signal device being configured to be able to flash the turn signal using a plurality of flashing methods, and changing the flashing method of the turn signal depending on the time that the movable contact and the fixed contact are in contact to pass electricity. According to this configuration, the blinking method of the turn signal can be changed according to the energization time of the contact, so the blinking method of the turn signal can be changed based on the energization state of one fixed contact. Therefore, it is easy to prevent the number of parts from increasing and the structure from becoming complicated, and the blinking method of the turn signal can be changed while maintaining a simple configuration.

[0107] (Configuration 2) A turn signal device as described in Configuration 1, further comprising a biasing member that biases a reaction force against the operator so that the operator, having moved from an initial position, returns to the initial position, and the amount of change in the reaction force changes at a predetermined position. According to this configuration, if the power supply time for switching the blinking mode of the turn signal elapses when the operator is moved from the contact start position to the change position, it is possible for the operator to easily understand that the blinking mode of the turn signal is being changed by the change in the operating force of the operator.

[0108] (Configuration 3) A turn signal device as described in Configuration 2, comprising: an operator having a longitudinal shape; and a guide provided within the movable range of the operator and guiding the operator, the guide having a plurality of inclined surfaces with which the operator comes into contact; and the plurality of inclined surfaces have mutually different inclination angles, which are angles with respect to an orthogonal direction perpendicular to the longitudinal direction of the operator in the initial position. According to this configuration, the reaction force acting on the operator can be changed by moving the operator while being in contact with the inclined surfaces of different inclination angles. Therefore, by switching the blinking mode of the turn signal between the inclined surfaces of different inclination angles, it is possible to make it easy for the operator to understand that the blinking mode of the turn signal is being switched.

[0109] (Configuration 4) When the operator moves from the initial position, the inclination angle of the inclined surface that the operator comes into contact with when passing a predetermined change position to which the operator moves after passing the contact start position is larger than the inclination angle of the inclined surface that the operator comes into contact with when passing a contact start position where the movable contact and the fixed contact begin to come into contact, and the multiple blinking modes include a predetermined number of blinking mode for blinking the turn signal a predetermined number of times and a continuous blinking mode for continuing the blinking of the turn signal, and the turn signal device described in Configuration 3 is characterized in that when the inclination angle of the inclined surface that the operator comes into contact with is larger than the inclination angle of the inclined surface that the operator comes into contact with when passing the contact start position. According to this configuration, the greater the inclination angle of the inclined surface with which the operator comes into contact, the greater the reaction force acting on the operator can be. Therefore, by making it possible to operate the operator without using any force up to the flashing mode a predetermined number of times and to operate the continuous flashing mode with some force, it is possible to make it easier for the operator to understand how to input the flashing mode.

[0110] (Configuration 5) A turn signal device provided in a vehicle, wherein the multiple blinking methods include a predetermined number of blinking methods for blinking the turn signal a predetermined number of times and a continuous blinking method for continuing the blinking of the turn signal, and the turn signal device described in configurations 1 to 4 is characterized in that when the vehicle is traveling at or above a predetermined speed, the turn signal is blinked only using the predetermined number of blinking method. With this configuration, an appropriate flashing method can be used according to the speed.

[0111] (Configuration 6) A winker device as described in any one of configurations 1 to 5, comprising: an operator having a longitudinal shape supported so as to be able to swing; a guide provided in the movable range of the operator and guiding the operator; and a biasing member biasing the operator toward the guide so as to abut the operator against the guide, wherein the guide has a plurality of inclined surfaces with which the operator comes into contact, the plurality of inclined surfaces having different inclination angles which are angles with respect to an orthogonal direction perpendicular to the longitudinal direction of the operator in an initial position, wherein when the operator is moved from the initial position, when the operator passes through a predetermined change position to which it moves after passing through a contact start position where the movable contact and the fixed contact begin to come into contact, the operator comes into contact with the inclined surface having an inclination angle different from the inclined surface with which it comes into contact at the contact start position. According to this configuration, if the power supply time for switching the blinking mode of the turn signal elapses when the operator is moved from the contact start position to the change position, it is possible for the operator to easily understand that the blinking mode of the turn signal is being changed by the change in the operating force of the operator.
