Abstract
A vehicle operable by muscle force and/or pedaling force including an electric drive, a control unit for actuating the electric drive, a crankshaft drive; a first detection device for detecting a cycle time across a predefined crank angle, a second detection device for detecting a force applied by a driver; and a third detection device for detecting a first time during which the force applied by the driver lies above a threshold value, or a second time during which the force applied by the driver lies below the threshold value, and the control unit is configured to calculate a quotient of the first time and the cycle time, or a quotient of the second time and the cycle time, or a quotient of the first time and the second time, and the control unit is further configured to control the electric drive as a function of the calculated quotient.
