The present invention relates to a device (100) for measuring a cycling cadence, a method (500) of operating a device (100) for measuring a cycling cadence, and a cycling cadence computer program. The device (100) comprises a motion sensor (such as, e.g., an accelerometer) for detecting a movement of the device (100) and for generating a motion signal (x, y, z) corresponding to the movement; a cadence determination unit (300) for determining cycling cadence based on the motion signal (x, y, z). The device (100) can be worn on the cyclist's wrist or arm (110). The motion sensor in the device is able to pick up the tiny movements of the arm or wrist that correspond to the cadence. Optionally, an algorithm is applied that can derive the cadence from a noisy signal.

A method and apparatus for providing an enhanced navigation solution for cycling applications is described herein. The navigation solution is about a device within a platform, which is a cycling platform such as for example a bicycle, a tricycle, or a unicycle amongst others. The device can be in any orientation with respect to the platform (such as for example in any location or orientation on the body of the cyclist). The device includes a sensor assembly. The sensors in the device may be for example, accelerometers, gyroscopes, magnetometers, barometer among others. The present method and apparatus can work whether in the presence or in the absence of navigational information updates (such as, for example, Global Navigation Satellite System (GNSS) or WiFi positioning).

A cyclocomputer includes: a body; a display provided on an upper surface of the body and displaying prescribed information; a storage provided in the body and storing therein data including at least a portion of the prescribed information; and an NFC tag provided in the body and allowing data communication with an NFC reader writer incorporated in a mobile wireless communication terminal. The cyclocomputer can transmit via the NFC tag to the mobile wireless communication terminal at least a portion of the data stored in the storage, and the cyclocomputer can receive from the mobile wireless communication terminal via the NFC tag at least a portion of other data stored in the mobile wireless communication terminal or input to the mobile wireless communication terminal via an operation unit of the mobile wireless communication terminal.

The invention discloses a bicycle pedaling frequency sensor, comprising a signal acquisition unit arranged on a circuit board and used for acquiring motion acceleration changes and/or angular velocity changes in different rotation directions of a middle axle in real time, a data transmission unit for transmitting the acquired data to a terminal, and a power supply for supplying power to each unit to work. When in use, the pedaling frequency sensor is fixed on the hollow middle axle of a bicycle, and the middle axle, a crank and pedals of the bicycle rotate synchronously; during riding motion, acceleration change and/or angular velocity change data is acquired in real time and transmitted to the corresponding processing terminal via the data transmission unit for processing, real-time rotating frequency of the middle axle of the bicycle is obtained, and then pedaling frequency data during riding is acquired. Because the pedaling frequency sensor skillfully implements counting through periodical changes of acceleration or/and angular velocity data and other data when the bicycle moves and does not need to carry out counting in a sensing mode through periodical relative motion between two separated components, the pedaling frequency sensor is simple in structure, small in size and works stably and reliably.

The present invention provides a method for detecting bicycle pedaling frequencies, in which an accelerometer of the body is used to detect the acceleration value of the pedal during pedaling, and the processing unit determines the periodical variations on acceleration increases and decreases, records the acceleration waveform, calculates the number of cycling in the pedal per minute based on the times that the sampled values within a unit time cross over the central line of the acceleration value, and also transfers tempo data to an electronic device by way of a wireless communication circuit and displays the pedaling frequency of the pedal via a screen so as to allow a user to promptly appreciate relevant information during riding and facilitate appropriate adjustments and controls on pedaling tempo and force.

A human-powered vehicle control device includes a controller that is configured to control a motor assisting in propulsion of a human-powered vehicle. The controller is configured to control the motor in a first control state in a case where a first parameter increases. The first parameter includes at least one of rotational speed of a crank of the human-powered vehicle, power of human driving force input to the human-powered vehicle, acceleration of the human-powered vehicle, jerk of the human-powered vehicle, and inclination angle of the human-powered vehicle. The controller is configured to control the motor in a second control state that differs from the first control state in a case where the first parameter decreases.
