Abstract
A pedal drive system, in particular for an electric vehicle or a training apparatus, and for generating electrical power from muscle power of a user with at least one pedal and an electric generator, connected mechanically with said at least one pedal, is provided. To improve the haptic feel and feedback at the pedal, a control unit is provided for controlling a feedback torque, applied at said pedal, wherein the control unit comprises a haptic renderer, configured for control of said feedback torque based on at least one predefined pedal reference trajectory.

Pedal drive system for generating electrical power from muscle power of a user with at least
- one pedal;
- an electric generator, connected mechanically with said at least one pedal;
- and
- a control unit for controlling a feedback torque, applied at said pedal;
- wherein
- the control unit comprises a haptic renderer, configured for control of said feedback torque based on at least one predefined pedal reference trajectory and, wherein the control unit further comprises an inertia modeler, configured to iteratively adapt the at least one pedal reference trajectory, which adapted pedal reference trajectory is provided to the haptic renderer for control of said feedback torque.
Method of operating a pedal drive system for generating electrical power from muscle power of a user with at least one pedal and an electric generator, connected mechanically with said at least one pedal, wherein a feedback torque, applied at said pedal, is controlled based on at least one predefined pedal reference trajectory, and wherein the at least one pedal reference trajectory is iteratively adapted.
