A bicycle power meter includes a strain gauge, a signal processing unit, a processor, and a signal transmitter. The strain gauge is disposed on at least one of an outer peripheral wall and an inner peripheral wall of a stem of a bicycle. The signal processing unit connected to the strain gauge by signal correspondingly outputs an electrical signal based on a deformation of the stem detected by the strain gauge. The processor connected to the signal processing unit by signal receives the electrical signal sent by the signal processing unit and calculates a measuring value based on the electrical signal and sends the measuring value in an output signal. The signal transmitter connected to the processor by signal receives the output signal sent by the processor and converts the output signal to a wired or wireless signal and sends the wired or wireless signal to a terminal device.

A method for controlling electronic shifting of a bicycle includes identifying, by a processor, a torque at a crank arm of the bicycle. The processor compares the identified torque or a parameter based on the identified torque to a predetermined band. The predetermined band has an upper limit and a lower limit. The processor determines a target cadence based on the comparison. The processor determines a cadence band based on the determined target cadence. The method also includes controlling the electronic shifting of the bicycle based on the determined cadence band. The controlling of the electronic shifting of the bicycle includes actuating a motor of a derailleur of the bicycle for the electronic shifting of the bicycle when a cadence of the bicycle is outside of the determined cadence band.

There is provided a method comprising receiving at a controller an input comprising a channel output from an input channel of a vehicle. The input is triggered by an operation of the vehicle by an operator. The input channel has a corresponding direct operational manifestation. The method also comprises comparing at the controller the input with a set of input patterns to select from the set of input patterns a target input pattern corresponding to the input, and generating at the controller a control output corresponding to the target input pattern. The control output is configured to cause in the vehicle a target operational manifestation different than the direct operational manifestation. Furthermore, the method comprises sending the control output from the controller to the vehicle.
