In this embodiment, the control unit 62 calculates the angular velocity of the disc brake rotor 80. The control unit 62 calculates the traveling speed of the vehicle 10 based on the angular velocity of the rotating body RT and the diameter of the rear wheel WR.

Preferably, the control unit 62 is configured to execute the second mode when it receives the change information regarding the change of the setting information. According to this configuration, the control unit 62 can execute the second mode without receiving the notification from the operating device 32, so that the operation of selecting the second mode by the passenger of the vehicle 10 can be eliminated.

Hereinafter, the operation of the control unit 62 in the second mode will be described. The control unit 62 is configured to receive change information regarding the change of the setting information and change the setting information based on the received change information. The control unit 62 updates the setting information stored in the storage unit 64 based on the received change information.

If the structure or configuration of the rotating body RT is changed after the vehicle 10 is completed, the number of times the electric change is detected changes when the rotating body RT makes one rotation.

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

The control unit 62 rotates the rotating body RT, and from the first detection of the magnet M by the second detection unit 54 to the next detection of 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 detection unit 52 is counted. The number of times this is counted is the change information regarding the change of the setting information.

Further, the second detection unit 54 may be configured to be built in the first detection unit 52. The magnet M is attached to the spoke S when the setting information is changed, and is removed from the spoke S after the setting information is changed.

In this case, when the second detection unit 54 detects the position information of the vehicle 10, the second detection unit 54 transmits the position information of the vehicle 10 to the control unit 62 as a detection result.

The control unit 62 obtains the moving distance of the vehicle 10 from the position information, and obtains the speed of the vehicle 10 from the moving distance and the moving time.

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 times of this electrical change is the change information regarding the change of the setting information.

Here, the operation of changing the setting information by the detection device 50 and the control device 60 will be described with reference to the flowchart shown in FIG. In the following, it is assumed that the detection device 50 includes a second detection unit 54 that detects the magnet M.

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

In step ST4, the second detection unit 54 rotates the rotating body RT attached to the vehicle 10 in the second mode, and detects the magnet M attached to the rotating body RT. The rotating body RT includes a disc brake rotor 80 and at least one of the 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 the change in the electrical state accompanying the rotation of the rotating body RT.

In step ST8, the control unit 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 the setting information. The control unit 62 rotates the rotating body RT, and from the first detection of the magnet M by the second detection unit 54 to the next detection of 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 detection unit 52 is counted. The number of times this is counted is the change information regarding the change of the setting information.

In step ST10, the control unit 62 changes the setting information stored in the storage unit 64 based on the change information received in the step 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 regarding 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 portion RT2 as the rotating body RT rotates, with the conductor portion RT2 of the disc brake rotor 80 as a detection target.

In step ST14, the control unit 62 reads out 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 step of step ST12 and the setting information read out in the step of step ST14. In this embodiment, the control unit 62 calculates the angular velocity of the disc brake rotor 80.
