Control method and control unit for adapting a velocity of the pushing aid of an electric bicycle

A control unit for operating a pushing aid of an electric bicycle, the electric bicycle including at least one electric motor configured to drive the electric bicycle and a gearshift configured to change a transmission ratio between a pedal crank axle and a rear wheel axle, the control unit comprising:

• at least one computing unit configured to:
• detect an activation of the pushing aid;
• and
• in response to detecting the activation:
• generate a control signal configured to actuate the at least one electric motor as a function of a maximum velocity of the pushing aid to generate a velocity of the electric bicycle;
• sense a motor rotational speed of the at least one electric motor;
• sense the velocity of the electric bicycle;
• determine an engaged transmission ratio of the gearshift as a function of the sensed motor rotational speed and the sensed velocity;
• and
• adapt the velocity of the electric bicycle by regulating the control signal as a function of the determined engaged transmission ratio and the maximum speed of the pushing aid.

An electric bicycle comprising:

• at least one electric motor configured to drive the electric bicycle;
• a gearshift configured to change a transmission ratio between a pedal crank axle and a rear wheel axle;
• a sensor configured to sense a velocity of the electric bicycle;
• and
• a control unit having at least one computing unit configured to:
• detect an activation of a pushing aid;
• and
• in response to detecting the activation:
• generate a control signal configured to actuate the at least one electric motor as a function of a maximum velocity of the pushing aid to generate the velocity of the electric bicycle;
• sense a motor rotational speed of the at least one electric motor;
• sense, with the sensor, the velocity of the electric bicycle;
• determine an engaged transmission ratio of the gearshift as a function of the sensed motor rotational speed and the sensed velocity;
• and
• adapt the velocity of the electric bicycle by regulating the control signal as a function of the determined engaged transmission ratio and the maximum speed of the pushing aid.
