摘要： A method and a device for controlling an additional electric or motor drive of a vehicle that can be driven at least partially by the rider using a pedal drive. To derive the control of the drive, at least one first rotational movement variable is detected that represents the rotational movement of the pedals or the pedaling movement of the crank performed by the rider. The first rotational movement variable can be detected by one or more sensors. The drive is controlled or regulated dependent on a second rotational movement variable that is derived from the first rotational movement variable. At least one time constant that influences the follow-up time of the actuated or regulated drive is taken into consideration in addition to the first rotational movement that represents the pedaling movement of the rider. The time constant used may be varied to calculate the second rotational movement variable.

摘要： A method for controlling an electric bicycle that can be operated with motor force and/or with pedal force is disclosed. The method includes (i) providing a trigger signal for enabling the activation of a walk mode to a control unit of the electric bicycle, (ii) providing a measurement signal of a sensor device regarding a property of the electric bicycle and/or regarding a component comprised by the electric bicycle to the control unit, (iii) detecting plausibility of the trigger signal on the basis of the provided measurement signal, and (iv) controlling the electric bicycle by enabling the activation of the walk mode in accordance with the detection of the plausibility of the trigger signal. Also disclosed is an electric bicycle that can be operated with motor force and/or with pedal force.

摘要： A method for controlling an electric motor of an electric bicycle for driving the electric bicycle. The method includes: detecting a longitudinal acceleration of the electric bicycle in the direction of the longitudinal axis of the electric bicycle; and generating a motor torque with the aid of the electric motor as a function of the detected longitudinal acceleration, the motor torque being adapted until a predefined setpoint acceleration is reached or exceeded or undershot.

摘要： A method for controlling an electric drive motor of an electrically drivable bicycle includes determining a cadence of a rider of the bicycle, and operating the electric drive motor under specification of (i) a first predefined target speed for the electric drive motor, which is lower than the cadence of the rider, and (ii) a first predefined torque for the electric drive motor, when the determined cadence of the rider exceeds a predefined cadence threshold value. The method further includes operating the electric drive motor under specification of (i) a second predefined target speed for the electric drive motor, which is higher than the first target speed, and (ii) a second predefined torque for the drive motor, when a rider torque exerted by the rider on a drive train of the bicycle exceeds a first predefined rider torque threshold value.

摘要： A method for controlling motor assistance provided by a motor of an electric bike is disclosed. The method includes determining a variable rate of change of a governing factor, which defines the extent to which a governing factor changes over a defined time interval The rate of change is selected such that the governing factor is decremented when a current speed is greater than a target speed, and the governing factor is incremented when the current speed is less than the target speed. The method further includes adjusting an existing governing factor based on the rate of change of the governing factor determined. The method also includes applying the governing factor calculated to a motor assistance determined for actuating the motor. A greater governing factor results in greater motor assistance than a comparatively lesser governing factor.

摘要： A device for controlling a motor of an electric bicycle. The device includes a control electronics system that is set up to control a torque of the motor in a normal operating mode based on an acquired driver torque; to detect during normal operation whether, at the current motor torque, no rotation of the motor is taking place even though a driver torque is being exerted, and to control the motor to continue to provide the motor torque in a blocking operating mode if it has been detected that at the present motor torque no rotation of the motor is taking place even though a driver torque is being exerted.
