Abstract: An operating method for a motor drive of a vehicle drivable by muscle power and additionally by motor power, and, in particular, for an electric bicycle, an e-bike, a pedelec, an S-pedelec and the like. The method includes the steps: (i) ascertaining whether and/or in what way an obstacle on a driving route of the vehicle is present directly at the vehicle; (ii) conditionally adapting an operating state of the motor drive as a function of a result of the ascertainment; and (iii) driving the vehicle with the aid of the motor drive in the adapted operating state, as well as to a corresponding control unit and to a vehicle per se.

Abstract: A method for operating a drive unit of an electric bicycle is disclosed. The method includes determining a temporary actual torque curve of a driver torque generated by a muscle force of a driver of the electric bicycle. The method further includes estimating a future torque curve by extrapolating the determined actual torque curve. In addition, the method includes determining whether the estimated future torque curve falls below a predetermined first torque threshold within a predetermined first time frame. The method also includes controlled reduction of a motor torque generated by way of the drive unit when the estimated future torque curve within the first time frame falls below the first torque threshold.

Abstract: 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.

Abstract: A control device of a drive of an electric bicycle is disclosed. The control device is designed to (i) receive and/or retrieve a rider's input torque applied by a rider of the electric bicycle, (ii) determine an output torque based on the rider's input torque in a first value range of the rider's input torque according to a first rule, in a second value range of the rider's input torque according to a second rule and in a third value range of the rider's input torque according to a third rule, (iii) determine a supporting torque based on the output torque, and (iv) control the drive in accordance with the supporting torque. The second value range directly adjoins the first value range and the third value range. The first rule and the second rule and the third rule are different from one another. And the second rule is a continuous function with the rider's input torque as input parameter.

Abstract: A method for switching a gear ratio of a switchable gear mechanism of a vehicle, which includes an electric motor for driving the vehicle, includes: generating a motor torque with the electric motor; determining an upcoming gear change; reducing the amount of the generated motor torque depending on the determined gear change; and changing the gear ratio of the switchable gear mechanism during a predetermined timespan according to the reduction in the amount of the generated motor torque. At least one motor torque pulse is generated by the electric motor during the predetermined timespan.

Abstract: A method for changing a transmission ratio of an electrically controllable gearing of a bicycle, in particular of an electric bicycle, includes (i) measuring a pedaling frequency of the bicycle rider on the pedal shaft, (ii) measuring a pedaling force of the bicycle rider, and (iii) determining a gear change operating state on the basis of the measured pedaling frequency and on the basis of the measured pedaling force if the measured pedaling frequency is less than or equal to a lower frequency threshold value or is greater than or equal to an upper frequency threshold value, and/or the measured pedaling force is less than or equal to a lower force threshold value or is greater than or equal to an upper force threshold value. After determining the gear change operating state, a control signal is generated for the gearing according to the determined gear change operating state.

Abstract: 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.

Abstract: A method and a drive system for adapting a drive assist by an electric drive motor of an electrically drivable bicycle. The method includes: ascertaining an instantaneous rider torque exerted by a rider of the bicycle on a drive train of the bicycle, ascertaining rider torque statistics based on a plurality of rider torques ascertained over time, ascertaining an assignment rule between the rider torque statistics and a predefined target load spectrum for the bicycle, the assignment rule approximating the rider torque statistics to the target load spectrum, establishing a motor torque corresponding to the instantaneous rider torque, based on the assignment rule, and operating the electric drive by specifying the ascertained motor torque.

Abstract: A method for controlling a motor assistance provided by a motor of an electric bicycle is disclosed. The method includes controlling a motor assistance by the motor based on a first control value when the bicycle is moved at a speed below a first limit speed, wherein the first control value is calculated by way of a first regulation algorithm. The method also includes controlling the motor assistance by the motor based on a second control value, after a transition phase has been completed, the second control value being calculated by way of a second regulation algorithm, the second regulation algorithm controlling the motor assistance in such a way that the speed of the bicycle assumes a downward regulation speed.
