Method for the Open-Loop Control of a Drive Device

A method for open-loop control of a drive device for assisting a vehicle at least intermittently operable by muscle power is provided. The vehicle includes a driving wheel drivable by drive force provided from the drive device, and a crank apparatus rotatable by a rider of the vehicle. The method in...

Beschreibung
Zusammenfassung:	A method for open-loop control of a drive device for assisting a vehicle at least intermittently operable by muscle power is provided. The vehicle includes a driving wheel drivable by drive force provided from the drive device, and a crank apparatus rotatable by a rider of the vehicle. The method includes: (S1) querying a predetermined operating mode of the drive device specifiable by the rider of the vehicle; (S2) detecting a rotational speed of the driving wheel; (S3) detecting a rotational speed of the crank apparatus; (S4) determining a synchronous operation with respect to the rotational speed of the driving wheel and the rotational speed of the crank apparatus based on a transmission ratio between the crank apparatus and the driving wheel; and (S6) controlling the drive device with a predefined drive power regardless of a muscle power introduced into a crank apparatus when the predetermined operating mode is present and the synchronous operation is present.
