Abstract
A method for controlling a shift system of a bicycle includes, in particular during pedaling, (i) acquiring sensor data representing a posture of a rider of the bicycle relative to the bicycle, (ii) recognizing a transition of the rider from a seated position to a standing position based on the sensor data acquired, and (iii) decreasing a gear ratio of the shift system in a controlled manner in response to recognizing the transition of the rider from the seated position to the standing position.
Claims17
A method for controlling a shift system of a bicycle, comprising:
- acquiring sensor data representing a posture of a rider of the bicycle relative to the bicycle;
- recognizing a transition of the rider from a seated position to a standing position, or from the standing position to the seated position, based on the sensor data acquired;
- and
- decreasing a gear ratio of the shift system in a controlled manner in response to recognizing the transition of the rider from the seated position to the standing position, or increasing the gear ratio of the shift system in a controlled manner in response to recognizing the transition of the rider from the standing position to the seated position,
- wherein the controlled decrease and/or increase in the gear ratio is performed so as to set a target pedaling frequency that is an increase and/or decrease of a predefined percent or absolute amount compared to a current pedaling frequency.
A method for controlling a shift system of a bicycle, comprising:
- acquiring sensor data representing a posture of a rider of the bicycle relative to the bicycle;
- recognizing a transition of the rider from a seated position to a standing position, or from the standing position to the seated position, based on the sensor data acquired;
- and
- decreasing a gear ratio of the shift system in a controlled manner in response to recognizing the transition of the rider from the seated position to the standing position, or increasing the gear ratio of the shift system in a controlled manner in response to recognizing the transition of the rider from the standing position to the seated position,
- wherein:
- an automatic activation of the shift system is performed based on predetermined characteristic shifting profiles, and
- the controlled decrease and/or increase of the gear ratio of the shift system is performed by an adjustment between a predetermined standing characteristic shifting profile and a predetermined sitting characteristic shifting profile of the predetermined shifting profiles.
A method for controlling a shift system of a bicycle, comprising:
- acquiring sensor data representing a posture of a rider of the bicycle relative to the bicycle;
- recognizing a transition of the rider from a seated position to a standing position, or from the standing position to the seated position, based on the sensor data acquired;
- and
- decreasing a gear ratio of the shift system in a controlled manner in response to recognizing the transition of the rider from the seated position to the standing position, or increasing the gear ratio of the shift system in a controlled manner in response to recognizing the transition of the rider from the standing position to the seated position,
- wherein the recognition of the rider's transition from the seated position to the standing position is performed in response to an acquisition of sensor data representing a brief pause of the bicycle, and
- wherein the recognition of the transition of the rider from the seated position to the standing position is performed in response to a simultaneous recognition of the sensor data representing the brief pause of the bicycle and sensor data representing braking-free operation of the bicycle.
