  • Publication number: 20260167296
    Abstract: A method for operating a pedal-driven vehicle is disclosed. The pedal-driven vehicle includes a drive for providing a drive torque for propelling the pedal-driven vehicle, a control unit, and a gearshift for providing a variable transmission ratio. The method includes (i) providing shift information for a planned shift operation comprising a primary target drive torque, (ii) providing a secondary target drive torque, (iii) selecting a target drive torque from the primary target drive torque and the secondary target drive torque, and (iv) controlling the drive such that the drive torque provided by the drive corresponds to the selected target drive torque.

  • Publication number: 20260167301
    Abstract: A method is disclosed for operating a pedal-driven vehicle that includes at least one drive for providing a drive torque for propelling the pedal-driven vehicle, a gearshift for providing a variable transmission ratio, a control unit, and at least one detection unit. The method includes (i) detecting a drive torque provided by the drive, as well as a drive speed of the drive, in particular by way of a detection unit, and (ii) adjusting at least one operating parameter of the gearshift as a function of the drive torque and/or the drive speed and/or a drive power provided by the drive.

  • Publication number: 20260167300
    Abstract: A method is disclosed for operating a gearshift for a pedal-driven vehicle that includes a control unit and at least one user interface for manually triggering a shift operation. The method includes (i) receiving a first shift instruction including an indication of origin, in particular by the control unit, (ii) receiving a second shift instruction including an indication of origin, in particular by the control unit, wherein the indication of origin of the first shift instruction is different from the indication of origin of the second shift instruction, and (iii) adjusting the operation of the gearshift as a function of the first and/or the second shift instruction.

  • Publication number: 20260167302
    Abstract: A method is disclosed for operating a pedal-driven vehicle that includes a gearshift for providing a variable transmission ratio, a control unit, and a detection unit. The method includes (i) detecting at least one travel parameter, (ii) providing a shift recommendation when at least one travel parameter is outside a predetermined value range, (iii) detecting a rider-generated shift release, and (iv) implementing the shift recommendation in response to the shift release.

  • Publication number: 20260167298
    Abstract: A method is disclosed for operating a pedal-driven vehicle including at least one drive for providing a drive torque for propelling the pedal-driven vehicle, a gearshift for providing a variable transmission ratio, and a control unit. The method includes (i) providing a first drive torque by way of the drive, (ii) providing shift information for a planned shift operation, the shift information including a shift direction specification, in particular by way of the gearshift, (iii) determining a second drive torque as a function of the shift information, in particular by the control unit, wherein the second drive torque is less than or equal to the first drive torque, and (iv) controlling the drive such that the drive torque provided by the drive corresponds to the second drive torque, in particular by way of the control unit.

  • Publication number: 20260167299
    Abstract: A method for operating a pedal-driven vehicle, in particular, a bicycle, a pedal-driven vehicle, a computer program product, a computer-readable medium, and a data carrier signal are disclosed. The pedal-driven vehicle includes a gear shift and a control unit. The method includes (i) determining an actual speed of the pedal-driven vehicle, (ii) determining a shift threshold for the gear shift as a function of the actual speed, (iii) calculating, by way of the control unit, a shift threshold displacement as a function of the actual speed and the shift threshold, and (iv) operating, by way of the control unit, the gear shift as a function of the shift threshold displacement.

  • Publication number: 20260159194
    Abstract: A method for operating a pedal-driven vehicle, a pedal-driven vehicle, a computer program product, a computer-readable data carrier, and a data carrier signal are disclosed. The method includes ascertaining a first speed which is specific to the pedal-driven vehicle. The method further includes ascertaining a second speed or a third speed which is specific to the pedal-driven vehicle. The method also includes calculating, by a control unit, a final speed as a function of the first speed and (i) the second speed, or (ii) the third speed. In addition, the method includes operating, by the control unit, the pedal-driven vehicle as a function of the final speed.
