Abstract: The spool brake device is equipped with a brake unit, a detector, and a controller. The controller controls the braking force by the brake unit based on the variation of the rotational speed of the spool detected by the detection unit. When the rotational speed is increasing, the controller controls the braking force by the brake unit in the regular braking mode. In the regular braking mode, the controller changes the braking force by the brake unit according to the rotational speed of the spool. In addition to it, when the rotational speed of the spool stops, the controller is to control the braking force by the brake unit in the first braking mode, during a period of predetermined time. In the first braking mode, the controller makes a braking force by the brake unit that is less than the braking force in the regular braking mode. In addition, after the predetermined time, the controller may make a braking force in a second braking mode by the braking unit that is less than the braking force in the first braking mode.

Abstract: A spool brake device for a fishing reel includes a velocity detector, a spool controller and a spool brake. The velocity detector is configured to detect a rotational velocity of a spool. The spool controller includes an acceleration generator, an acceleration determiner and a brake time predictor. The accelerator generator is configured to generate time-series data of a rotational acceleration based on the rotational velocity. The acceleration determiner is configured to determine whether the rotational acceleration has satisfied a predetermined condition based on the time-series data of the rotational acceleration. The brake time predictor is configured to set a prediction starting time based on a point of time at which the rotational acceleration has satisfied the predetermined condition and to predict a brake starting time of the spool based on the prediction starting time. The spool brake is configured to start braking the spool at the brake starting time.

Abstract: The spool brake device is equipped with a brake unit, a detector, and a controller. The controller controls the braking force by the brake unit based on the rotational speed of the spool detected by the detector. When the rotational speed is less than the predetermined rotational speed, the controller controls the braking force by the brake unit in the regular braking mode. In the regular braking mode, the controller changes the braking force by the brake unit according to the rotational speed. On the other hand, when the rotational speed is equal to or higher than the predetermined rotational speed, the controller controls the braking force by the brake unit in the emergency braking mode, during the period of predetermined time. In the emergency braking mode, the controller makes the braking force by the brake unit larger than the braking force in the regular braking mode.

Abstract: A human-powered vehicle component includes a communication device and an electronic controller. The communication device is configured to communicate with a first electric component and a second electric component differing in type from the first electric component. The electronic controller is configured to be operable in a first control state to manage the first electric component and a second control state managed by the second electric component. The electronic controller is configured to be operable in the first control state upon determining the communication device can communicate with the first electric component but cannot communicate with the second electric component. The electronic controller is configured to be operable in the second control state upon determining the communication device can communicate with the second electric component.
