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 user-defined pedal reference trajectory.

Abstract: The invention relates to a converter system (1, 1?, 1?) for an electric vehicle and in particular a lightweight electric vehicle. The converter system (1, 1?, 1?) has a supporting housing (10, 10?, 10?) for connecting to the vehicle, has an electromechanical energy converter arranged at least partially in the supporting housing (10, 10?, 10?), said electromechanical energy converter having at least one stator (21, 21?) and a rotor (22, 22?) which is rotatable relative to the stator (21, 21?) about a drive axis (7, 40), and has a power transmitting device which connects the rotor (22, 22?) to a connection element.
