The second detection unit 54 is configured to detect the magnet M attached to the rotating body RT. When detecting the magnet M, the second detection unit 54 transmits the detection result to the control unit 62.

  The controller 62 rotates the rotating body RT so that the second detector 54 first detects the magnet M and then detects the magnet M, that is, until the rotating body RT makes one rotation. During this period, the number of electrical changes detected by the first detector 52 is counted. This counted number is the change information regarding the change of the setting information.

The control unit 62 determines the number of rotations of the rotating body RT based on the speed of the vehicle 10. The control unit 62 obtains the number of electrical changes per rotation of the rotating body RT based on the number of rotations of the rotating body RT and the number of electrical changes detected by the first detection unit 52. The number of electrical changes is change information related to the change of the setting information.

  When the passenger of the vehicle 10 selects the second mode using the operation device 32, the control unit 62 executes the second mode for changing the setting information stored in the storage unit 64 in step ST2.

  In Step ST4, the second detection unit 54 detects the magnet M attached to the rotating body RT by rotating the rotating body RT attached to the vehicle 10 in the second mode. The rotating body RT includes at least one of a disc brake rotor 80 and wheels.

  In step ST6, the first detection unit 52 detects the rotation information of the rotating body RT. The first detection unit 52 detects the rotation of the rotating body RT based on a change in the electrical state accompanying the rotation of the rotating body RT.

  In step ST8, the control part 62 receives the detection result by the process of step ST4, and the detection result by the process of step ST6 as change information regarding the change of setting information. The controller 62 rotates the rotating body RT so that the second detector 54 first detects the magnet M and then detects the magnet M, that is, until the rotating body RT makes one rotation. During this period, the number of electrical changes detected by the first detector 52 is counted. This counted number is the change information regarding the change of the setting information.

  In step ST10, the control part 62 changes the setting information memorize | stored in the memory | storage part 64 based on the change information received by the process of step ST8.

  Next, a procedure for calculating the traveling speed of the vehicle 10 based on the setting information will be described with reference to the flowchart shown in FIG. In the following, it is assumed that the first mode for acquiring information related to the rotation of the rotating body RT is selected.

  In step ST12, the control unit 62 acquires the number of detections of the detection target per unit time based on the detection result of the first detection unit 52. The first detection unit 52 detects the conductor part RT2 as the rotating body RT rotates with the conductor part RT2 of the disc brake rotor 80 as a detection target.

  In step ST14, the control unit 62 reads the setting information stored in the storage unit 64.

  In step ST16, the control unit 62 calculates the angular velocity of the rotating body RT based on the number of detections of the detection target acquired in the process of step ST12 and the setting information read out in the process of step ST14. In the present embodiment, the control unit 62 calculates the angular velocity of the disc brake rotor 80.

  In step ST18, the control unit 62 calculates the traveling speed of the vehicle 10 based on the angular speed of the rotating body RT and the diameter of the rear wheel WR.

As shown in FIG. 1, vehicle 10 further includes a braking device 140, a detection device 150, and a control device 160. The braking device 140 is attached to the front fork 16. The detection device 150 and the control device 160 are provided in the braking device 140 so as to detect the rotation of the front wheel WF outside the rotation RT. FIG. 7 shows the configuration of the hub assembly HAF of the front wheel WF and its surroundings. In FIG. 7, the braking device 140 is omitted. The detection device 150 includes a first detection unit 152 and a second detection unit 154. The control device 160 includes a control unit 162 and a storage unit 164.

  The housing 170 accommodates the detection device 150 and the control device 160. In one example, the housing 170 is made of a material that hardly affects the change in impedance detected by the first detection unit 152 as the rotating body RT rotates. The housing 170 is at least partially made of a non-metallic material. In one example, the housing 170 is entirely made of a non-metallic material. The housing 170 includes a mounting portion 170A.

  The rotating body RT includes a hub body HAF1 of a hub assembly HAF that is rotatably supported by the vehicle 10 among the components of the wheel W. The rotating body RT includes a plurality of insulating portions RT1 disposed in the circumferential direction of the rotating body RT, and a conductor portion RT2 disposed between the plurality of insulating portions RT1. The first detection unit 152 is configured to detect the conductor part RT2 intermittently with the rotation of the rotating body RT, with the conductor part RT2 as a detection target. In addition, the 1st detection part 152 may be the structure which detects the spoke S intermittently with rotation of the rotary body RT by making the spoke S into a detection target.

  The conductor portion RT2 includes a flange HAF2 of the hub body HAF1 to which the spoke S is attached. The flange HAF2 is made of, for example, a metal material. The insulating portion RT1 is provided on the flange HAF2 of the hub body HAF1, and includes at least one opening HAF3 to which the spoke S is not attached. The plurality of openings HAF3 are arranged, for example, at equal intervals in the circumferential direction of the flange HAF2. The number of openings HAF3 is preferably included in the range of 5 to 15. In one example, the number of openings HAF3 is eight.

  The attachment portion 170A is attached to the main body 12 of the vehicle 10. In one example, the attachment portion 170A is attached to the front fork 16 so that the first detection portion 152 and the rotating body RT face each other in the direction along the center axis CA of the disc brake rotor 180. Specifically, the attaching portion 170A is attached to the front fork 16 so that the first detecting portion 152 can alternately detect the insulating portion RT1 and the conductor portion RT2 by a change in impedance accompanying the rotation of the rotating body RT. The control unit 162 can acquire the traveling speed of the vehicle 10 based on the detection result of the first detection unit 152.

  As mentioned above, although embodiment of this invention was described, embodiment is not limited by the content of this embodiment. In addition, the above-described constituent elements include those that can be easily assumed by those skilled in the art, those that are substantially the same, and those in a so-called equivalent range. Furthermore, the components described above can be combined as appropriate. Furthermore, various omissions, substitutions, or changes of the components can be made without departing from the spirit of the above-described embodiment.
