As shown in fig. 3, the notification system 10 further includes: and an electric drive unit 14 for driving the brake device BD to brake the rotor F1 via the friction member BP. The electric drive unit 14 includes a plurality of electric drive units 14 that drive the brake devices BD, respectively. In the present embodiment, the electric drive unit 14 includes the electric drive unit 14 that drives one brake device BD and the electric drive unit 14 that drives the other brake device BD. The electric drive unit 14 is, for example, an electric motor. The electric drive unit 14 is not limited to an electric motor as long as it is electrically driven, and may be a solenoid valve or the like. In the present embodiment, the electric drive unit 14 is provided in the casing of the main body BC. The electric drive unit 14 is driven to electrically drive the main body BC, and the pair of friction members BP sandwich the rotor F1 to brake the rotor F1. The electric drive unit 14 may be provided separately from the main body BC. Specifically, the electric drive unit 14 may be provided at any position such as the frame a1, the front fork a2, and the handle H.

The notification system 10 further includes: and a power supply for supplying electric power to the electric drive unit 14. The power supply is a battery BT (hereinafter, also referred to as "power supply BT") mounted on the human-powered vehicle a. The electric drive unit 14 is driven by electric power supplied from, for example, a power supply BT. The power source may also be a power source different from the battery BT. In this case, the power supply may be provided in the body frame a1 of the human-powered vehicle a so as to supply power to each brake device BD, or may be provided in each brake device BD so as to supply power to each brake device BD individually.

The notification system 10 further includes: and a control unit 16 for controlling the electric drive unit 14. The control unit 16 is a CPU (Central Processing Unit) or an MPU (micro Processing Unit). The control unit 16 controls one of the electric drive units 14 in accordance with the operation of one of the operation devices OD, thereby operating one of the brake devices BD. The control unit 16 controls the other electric drive unit 14 in accordance with the operation of the other operating device OD, thereby operating the other brake device BD. The control unit 16 may operate the braking devices BD (two braking devices BD in the present embodiment) by controlling the electric drive units 14 in accordance with the respective operations of the pair of operation devices OD. In this case, the ratio of the braking force of each brake device BD in one of the operating devices OD may be made different from the ratio of the braking force of each brake device BD in the other operating device OD.

Further, the control unit 16 controls each electric drive unit 14 based on the relative rotation speed of the front wheel WF and the rear wheel WR to adjust the braking force to the rotary member F1. Specifically, when the rotational speed of one of the front wheel WF and the rear wheel WR is slower than the rotational speed of the other of the front wheel WF and the rear wheel WR by a predetermined speed or more, the control unit 16 controls each electric drive unit 14 so as to temporarily (intermittently) release the brake applied to the one of the front wheel WF and the rear wheel WR. That is, the control unit 16 is configured to perform abs (antilock Brake system) control on each electric drive unit 14. As such ABS control, the front wheel WF can be executed based on the rotational speed of the front wheel WF and the traveling speed of the human-powered vehicle a (vehicle body speed), and the rear wheel WR can be executed based on the rotational speed of the rear wheel WR and the traveling speed of the human-powered vehicle a.

The notification system 10 further includes a storage section 18. The storage unit 18 includes a nonvolatile memory and a volatile memory. The storage unit 18 stores various programs for control and preset information, for example. The information stored in advance in the storage unit 18 may be configured to be changeable by a predetermined input device (not shown). The control unit 16 develops and executes various programs in the storage unit 18, thereby executing various controls of the brake device BD.

The storage unit 18 stores, for example, a control pattern related to control of the electric drive unit 14 by the control unit 16. The control mode includes at least one of an adjustment mode and an automatic mode. The adjustment mode is a control mode for adjusting the gap between the rotating body F1 and the friction member BP. The automatic mode is a control mode for automatically controlling the electric drive unit 14. The control mode of the control unit 16 is arbitrarily selected in accordance with, for example, an operation of a predetermined operation device (not shown). In the adjustment mode, the control unit 16 controls the electric drive unit 14 to adjust the gap between the rotating body F1 and the friction member BP in accordance with the operation of a predetermined operating device. In the automatic mode, the control unit 16 controls the electric drive unit 14 so that the brake device BD automatically operates in accordance with, for example, the traveling speed of the human-powered vehicle a, the inclination angle of the human-powered vehicle a in the front-rear direction, and the rotation speed of the crank C. Specifically, in a state where the travel speed of the human-powered vehicle a exceeds the upper limit value under the predetermined condition, the electric drive unit 14 is controlled to automatically perform braking by the brake device BD.

The control unit 16 acquires brake-related information from, for example, various members constituting the human-powered vehicle a and various detection devices (not shown) mounted on the human-powered vehicle a, and causes the notification unit 12 to notify the acquired brake-related information. The braking-related information includes at least one of the information shown in the following first to seventh examples.

(modification example)

The description of the above embodiments is an example of the manner in which the notification system according to the present invention can be employed, and is not intended to limit the manner thereof. The notification system according to the present invention may be configured by combining at least two modifications of the above-described embodiments and at least two modifications that are not mutually inconsistent, for example, as shown below. In the following modification, the same reference numerals as in the respective embodiments are given to portions common to the embodiments, and therefore, description thereof is omitted.

The configuration of the display device SC can be changed arbitrarily. In the first example, the display device SC is provided on the vehicle body frame a 1. In the second example, the display device SC is provided in the front fork a 2. In the third example, the display device SC is provided on a fender (not shown) of the human-powered vehicle a.

The content of the braking-related information may be arbitrarily changed. In one example, in the first and second embodiments, the information related to the operation state of the ABS control may include information related to a switch controlled by the ABS. Specifically, in the case where the notification unit is provided in at least one of the operating device OD and the brake device BD, the information on the operating state of the ABS control may include information on the switch of the ABS control.

The type of the brake device BD can be changed arbitrarily. In the first example, the brake device BD is a rim brake device. In this case, the rotating body is a rim F2 (see fig. 1). In the second example, the brake device BD is a hydraulic brake device. The brake apparatus BD further includes an actuator (not shown) for driving the body BC with fluid. One example of a fluid as the power transmission medium is hydraulic oil. The actuator is driven by the electric drive unit 14, and the pressure of the fluid is applied to the friction member BP via the body BC. Therefore, the friction member BP comes into contact with the rotating body F1, braking the rotating body F1. In the third example, the brake device BD is a cable brake device. The brake apparatus BD further includes an actuator (not shown) that drives the main body BC via a cable. The actuator is driven by the electric drive portion 14, thereby pulling the cable to displace the friction member BP. Therefore, the friction member BP comes into contact with the rotating body F1, braking the rotating body F1. In a fourth example, it is a regenerative braking device. In this case, the braking device BD comprises an electric motor E1 of the electric assist unit E. The electric motor E1 is configured to be regenerative. According to a fourth example, the notification system 10 may omit the electric drive section 14. In a fifth example, the brake device BD is a mechanically driven brake device. According to a fifth example, the notification system 10 may omit the electric drive section 14.

The type of the human-powered vehicle a may be changed as desired. In a first example, the human-powered vehicle a is an on-highway bicycle, a mountain bike, a Cross bike (Cross bike), a city bike, a freight bike, or a recumbent bike. In a second example, the human-powered vehicle A is a scooter.
