The vehicle includes an electric drive, a crank mechanism, at least one torque sensor, which is configured to detect a torque applied by a rider onto the crank mechanism, in the form of a multitude of torque measuring signals, and a control unit, which is configured to generate a control signal for activating the electric drive as a function of at least one of the torque measuring signals.

The present disclosure relates to a control method for regulating the electric motor of an electric bicycle for push assistance for the electric bicycle. The control method comprises identification of activation of the push assistance by the cyclist. When activation is identified, the electric motor generates a torque for driving the electric bicycle as push assistance. Subsequently, an acceleration by the electric bicycle in the direction of the longitudinal axis of the electric bicycle is captured by means of a first sensor, wherein the acceleration results on the basis of a manual pushing or braking force of the cyclist. The captured acceleration is compared with an acceleration threshold value in a further step, wherein, in the event of the acceleration threshold value being exceeded, the electric motor is regulated on the basis of a change in the captured acceleration to adapt the torque.

A control method comprises at least one detection of activation of the pushing aid. When activation is detected, in the subsequent step a velocity of the electric vehicle and/or a constant starting torque are/is generated by actuation of the electric motor. The generated velocity of the pushing aid as a result of the actuation is dependent on the engaged transmission ratio of the gearshift. In order to adapt the velocity, the control method comprises sensing the current motor rotational speed of the electric motor and sensing the current velocity of the electric bicycle. The engaged transmission ratio is determined as a function of the sensed motor rotational speed and the sensed velocity. The adaptation of the velocity of the electric bicycle occurs in the subsequent step as a result of regulation of the electric motor as a function of the transmission ratio and the maximum velocity, which is not exceeded.

Control is then applied to the motor either as a reduction in the applied drive power output, e.g. in the form of the motor speed or torque, or as a complete shutoff or immobilization of the motor.
