Abstract
An actuation controller for a rider posture changing device of a human-powered vehicle comprises a detector and a controller. The rider posture changing device includes a first member, a second member, and an electrical actuator configured to move the second member relative to the first member. The detector is configured to detect actuation information relating to an actuation state in which the electrical actuator moves the second member relative to the first member. The controller is configured to evaluate the actuation state in accordance with the actuation information detected by the detector.
Claims17
An actuation controller for a rider posture changing device of a human-powered vehicle, the rider posture changing device including a first member, a second member, and an electrical actuator configured to move the second member relative to the first member, the actuation controller comprising:
- a detector configured to detect actuation information relating to an actuation state in which the electrical actuator moves the second member relative to the first member;
- and
- a controller configured to evaluate the actuation state in accordance with the actuation information detected by the detector, wherein
- the detector is configured to detect electrical-load information of the electrical actuator as the actuation information, and
- the electrical-load information includes one of an electrical power, a current, and a temperature of the electrical actuator.
An actuation controller for a rider posture changing device of a human-powered vehicle, the rider posture changing device including a first member, a second member, and an electrical actuator configured to move the second member relative to the first member, the actuation controller comprising:
- a detector configured to detect actuation information relating to an actuation state in which the electrical actuator moves the second member relative to the first member;
- and
- a controller configured to evaluate the actuation state in accordance with the actuation information detected by the detector, wherein
- the detector is configured to detect, as the actuation information, a first movement distance in which the second member is moved relative to the first member during a first predetermined period,
- the controller is configured to evaluate the actuation state as an abnormal state if the first movement distance is out of a first predetermined range,
- the abnormal state includes a first abnormal state,
- the controller is configured to evaluate the actuation state as the first abnormal state if the first movement distance is out of the first predetermined range,
- the controller is configured to count a first count value, and
- the controller is configured to increment the first count value if the controller evaluates the actuation state as the first abnormal state.
An actuation controller for a rider posture changing device of a human-powered vehicle, the rider posture changing device including a first member, a second member, and an electrical actuator configured to move the second member relative to the first member, the actuation controller comprising:
- a detector configured to detect actuation information relating to an actuation state in which the electrical actuator moves the second member relative to the first member;
- and
- a controller configured to evaluate the actuation state in accordance with the actuation information detected by the detector, wherein
- the detector is configured to detect electrical-load information of the electrical actuator as the actuation information, and
- the controller is configured to evaluate the actuation state as an abnormal state if the electrical-load information is equal to or more than a threshold.
