A control method for controlling an electric motor of an electric bicycle in dependence on an applied transmission ratio of a gear shift includes detecting a pedaling torque of the bicycle rider and detecting the applied transmission ratio of the gear shift. In addition, the control method controls the electric motor for the drive of the electric bicycle in dependence on the detected pedaling torque and the detected transmission ratio in order to generate a torque of the electric motor. The bicycle rider is thus supported by the electric motor while driving the electric bicycle in dependence on the applied transmission ratio.

Control method and devices for controlling the electric motor of an electric bicycle

A method for activating a motor of an electric two-wheeler, including the following steps: determining a position of a driver of the electric two-wheeler as a function of a first GPS signal, the first GPS signal having a temporal dependence on a starting position; determining a position of a virtual training partner as a function of a second GPS signal, the second GPS signal having a temporal dependence on the starting position; determining a distance between the position of the driver of the electric two-wheeler and the position of the virtual training partner; determining a slipstream effect as a function of a total front face which is formed by the electric two-wheeler and the driver and of the determined distance; and generating a motor torque as a function of the slipstream effect and/or of the determined distance.

In a method for controlling a pedal- and motor-driven bicycle, the motor in the vehicle being able to assist the driver at least in a pushing operation, the movement or state variable of the pedal is compared with a threshold value in the pushing operation, and the driving of the vehicle is modified at least briefly as a function of the exceeding or not attaining of this threshold value.

Method and device for controlling a pedal-operated vehicle

A method for detecting wear on at least one component of an electric bicycle includes: monitoring the operating condition of the at least one component with the aid of at least one sensor; detecting the stress on the component over the duration of operation; and displaying the need for service on a display unit as soon as a long-term load threshold defined for this component is reached, to inform the cyclist promptly of the need for service.

Cyclometer

A method for automatically controlling the gear of a gearshift of an electric bicycle. At least one actual operating parameter of a drive component of the electric bicycle is recorded by recording an operating variable of the drive component. The at least one actual operating parameter is compared to a setpoint default, which reflects an operating point of the electric drive, which is linked to a higher efficiency, a greater reliability or a greater durability of components of the electric drive or of the drive component than in response to an operation according to the at least one actual operating parameter. The at least one actual operating parameter is approximated to the setpoint default by changing the gear. A corresponding device for automatically controlling the gear is also described.
