[0052] As in Fig. 3 to Fig. As shown in Figure 5, a handlebar switch 50 is attached to the handlebar 21. The handlebar switch 50 comprises a switch housing 51, which is attached to the handlebar 21.

[0053] An instrument switch 59 is provided on a surface of the switch housing 51 on the rear of the motorcycle 1. This switch serves as an actuating switch for the operating indicator of the display instrument 39. The instrument switch 59 comprises an upper switch 52, a lower switch 53, a right switch 54, and a left switch 55, the upper switch 52, the lower switch 53, the right switch 54, and the left switch 55 generally being arranged in a cross shape. The right switch 54 and the left switch 55 are configured as a lever-type switch 56. The right switch 54 is activated when the lever-type switch 56 is tilted to the right, and the left switch 55 is activated when the lever-type switch 56 is tilted to the left.

[0054] Above the switch housing 51 is an operating mode switch 57. The operating mode switch 57 is configured to switch the driving mode, for example, to standard mode, sport mode, and the like.

[0055] Below the operating mode switch 57 of the switch housing 51 is a horn switch 58. The horn switch 58 is configured so that the act of pressing it activates a horn 88 (see Fig. 9) can trigger.

[0056] Below the horn switch 58 is a turn signal lever 61 of a turn signal switch 60.

[0057] Below the indicator lever 61 is a hazard warning switch 65. The hazard warning switch 65 is configured so that the indicators 38 on both sides flash simultaneously during the printing process.

[0058] A high beam switch 66 and a flash-to-pass switch 67 are arranged on a surface of the switch housing 51 on the front of the motorcycle 1, wherein the high beam switch 66 illuminates the high beam of the headlight 37 and the flash-to-pass switch 67 increases the headlight beam 37.

[0059] In the present embodiment, the high beam switch 66 of the headlight 37 also serves as a flash-to-pass switch 67, and the high beam switch 66 and the flash-to-pass switch 67 are operated by a lever switch 68.

[0060] As in Fig. 6 and Fig. As shown in Figure 7, a retaining element for the circuit board is housed in the switch housing 51. In the present embodiment, the circuit board retaining element is configured with a first circuit board retaining element 71, a second circuit board retaining element 72, and a third circuit board retaining element 73.

[0061] The first circuit board holder 71 is arranged so that it faces the rear of the motorcycle 1, and a first circuit board 74 is attached to the first circuit board holder 71. Switch electrodes 80 are arranged in the first circuit board 74, which are activated by actuating the upper switch 52, the lower switch 53, the right switch 54, the left switch 55, the mode switch 57, and the horn switch 58.

[0062] The second circuit board retaining element 72 is arranged below the first circuit board retaining element 71, and a second circuit board 75 is attached to the second circuit board retaining element 72. The switching electrodes 80, which are switched ON by actuating the turn signal switch 60, the turn signal cancel switch 64, and the hazard warning switch 65, are each arranged in the second circuit board 75.

The switching electrodes 80 are arranged in the third circuit board 76, which are activated by actuating the high beam switch 66 and the flash-to-pass switch 67; the high beam switch 66 and the flash-to-pass switch 67 dim the headlights 37.

[0064] Fig. Figure 9 is a circuit diagram that shows a circuit of the handlebar switch 50 of the present embodiment.

[0065] As in Fig. As shown in Figure 9, the switching electrodes 80 are arranged in the first circuit board 74, the second circuit board 75 and the third circuit board 76, and these respective switching electrodes 80 are connected in parallel for each of the circuit boards 74, 75, 76.

[0066] A signal line 81 is connected to one end of each switching electrode 80, and a ground line 82 is connected to the other end of the switching electrode 80. A resistor 83 and a capacitor 84 are connected between each signal line 81 and the ground line 82. Furthermore, a resistor 85 with a different resistance value is connected to the signal line 81 of each switching electrode 80. When two switching electrodes 80 are arranged on a circuit board, the resistor 85 is connected only to the signal line 81 of one switching electrode 80.

[0067] As described above, in the present embodiment the switching electrode 80 is configured with the resistance voltage divider, and an electric current with different voltages flows from the signal line 81 by actuating each actuating switch and turning on the switching electrode 80.

[0068] Furthermore, the first circuit board 74 is divided into a block of a circuit in which the upper switch 52, the lower switch 53, the right switch 54 and the left switch 55 are arranged, and into a block of a circuit in which the operating mode switch 57 and the horn switch 58 are arranged. Therefore, starting from the first circuit board 74, the signal lines 81 are brought out of the respective circuits divided into blocks.

[0069] In addition, a signal line 81 is led out from the second circuit board 75 and the third circuit board 76.

[0070] Furthermore, the ground lines 82 of the respective circuit boards are connected to each other and designed as one ground line 82.

[0071] When configured in this way, it is configured so that four signal lines 81 and one ground line 82 are each brought out from the first circuit board 74, the second circuit board 75 and the third circuit board 76.

[0072] It is configured such that each of the signal lines 81 and 82 is connected to a control unit 86. The electrical components, such as the headlight 37, the turn signals 38, and the horn 88, are connected to the control unit 86 via an analog line. Additionally, the instrument cluster 39 and an ECU 87 are connected to the control unit 86 via a CAN communication line, and a throttle actuator 89 is connected to the ECU 87.

[0073] The control unit 86 includes an A / D connector (not shown) which converts an analog signal output by each signal line 81 into a digital signal.

[0074] The control unit 86 is configured to determine, based on the voltage value of a signal transmitted by each signal line 81, which switching electrode 80 from among the switching electrodes 80 has been switched on. Furthermore, the control unit 86 is configured to control the operation of an electrical component corresponding to the switching electrode 80 that has been switched on.

[0075] As in Fig. As shown in Figure 8, the air filter box 31 is arranged as a body component between a pair of left and right main frames 16, which extend downwards and rearwards from the head tube 15, and the control unit 86 is supported above the air filter box 31. Thus, the control unit 86 is configured to be positioned above the main frames 16. Furthermore, the ECU 87 is supported above the air filter box 31.

[0076] Since the signal of each switching electrode 80 is an analog signal, it is necessary to reduce the distance to the control unit 86 so that interference is minimal, and it is permissible to arrange the control unit 86 near the handlebar 21 by placing the control unit 86 above the main frame 16, which is located behind the head tube 15 that supports the handlebar 21.

[0077] Since the control unit 86 is supported by the air filter box 31, the degree of freedom of attachment near the handlebar 21 is high and the control unit 86 can be supported without separate work of the main frame 16.

[0078] Fig. Figure 10 is a perspective view showing a brake lever 90 attached to the handlebar 21.

[0079] As in Fig.Figure 10 shows a lever support element 91 which is attached to the handlebar 21. The lever support element 91 has a two-part structure, which is sandwich-like and attached to the handlebar 21, and a recessed section 92 is arranged at an end section of the lever support element 91, wherein the recessed section 92 has a circular shape which surrounds the handlebar 21.

[0080] The end section of the brake lever 90 is pivotally attached to the other end section of the lever support element 91. A brake switch 93 is located near the brake lever 90 of the lever support element 91.

[0081] The brake switch 93 comprises a switch housing 94 and a switch 95, wherein the switch housing 94 has a box shape and the switch 95 is arranged on the side face of the switch housing 94. The switch housing 94 is attached to the side face of the lever support element 91 by a switch mounting element 96. The switch mounting element 96 is generally cranked, and an end section of the switch mounting element 96 is screwed to the lever support element 91.

[0082] The other end section of the switch fastening element 96 rests against the surface of the switch housing 94 and is configured such that the switch housing 94 is fastened to the lever support element 91 by the other end section of the switch fastening element 96.

[0083] A switch actuating element 97 is attached to the end section of the brake lever 90, and the switch actuating element 97 serves to actuate the switch 95. Therefore, it is configured such that the switch actuating element 97 switches the switch 95 ON / OFF by actuating the brake lever 90.

[0084] A connecting cable 98 is connected to the brake switch 93 and configured to output a signal generated by the ON / OFF actuation of the switch 95.

[0085] Next, the actions of the present embodiment will be explained.

[0086] In the present embodiment, e.g. when the turn signal lever 61 is actuated and the switching electrode 80 of the left switch 55 of the turn signal switch 60 is activated, the control unit 86 converts an analog signal transmitted by the signal line 81 into a digital signal, determines that the left switch 55 of the turn signal switch 60 has been actuated based on the voltage value of the signal line 81 and can operate the left turn signal 38.

[0087] Similarly, by actuating the upper switch 52, the lower switch 53, the right switch 54 and the left switch 55, which are intended for the operation of the display instrument 39, the display of the display instrument 39 can be operated via the control unit 86.

[0088] By pressing the horn switch 58, the horn 88 can also sound via the control unit 86. By pressing the hazard warning switch 65, the turn signals 38 on both sides can be made to flash simultaneously via the control unit 86. By pressing the high beam switch 66, the high beam and low beam of the headlight 37 can be switched via the control unit 86.

[0089] Furthermore, by actuating the operating mode switch 57 and switching the driving mode, the power of the engine 11 can be controlled to an output corresponding to the driving mode by changing at least the fuel injection quantity of the throttle valve actuator 89 by the control unit 86.

[0090] As described above, the operating switch in the present embodiment comprises at least the high beam switch 66, the turn signal switch 60, the turn signal cut-off switch 64, the hazard warning switch 65 and the instrument switch 59, wherein the high beam switch 66 dims a high beam of the headlight 37, the instrument switch 59 controls the operation of the display instrument 39, wherein the respective switches are resistance voltage divider switches, at least two to four switches from the respective switches are mounted on a circuit board 74, 75, 76, wherein the circuit board 74, 75, 76 includes the wiring of the signal line 81 and the ground line 82, the ground line 82 is common to the majority of the circuit boards and the signal line 81 and the ground line 82 are connected to the control unit 86, wherein the electrical components are connected to the control unit 86.

[0091] Since the operating switches are resistance voltage divider switches and most of them are grouped on a circuit board, the wiring can be simplified. Because control unit 86 is provided, the electrical components can also be operated correctly.
