Abstract: A method for operating a drive system that includes a plurality of components of an at least temporarily electrically driven bicycle is disclosed. The method includes (i) providing at least one requirement of a first component and a requirement of a second component from the plurality of components of the drive system, (ii) comparing the requirement of the first component with the requirement of the second component with regard to a thermal load situation of the first component and the second component, and (iii) adjusting an operating behavior of the first component and/or the second component based on the comparison.

Abstract: A method for assessing a control loop. In the method, the control loop is assigned one degree of fulfillment each with respect to at least three quality criteria. The surface area of a polygon having a geometry defined by the degrees of fulfillment is determined. An overall control quality of the control loop is evaluated on the basis of the surface area.

Abstract: A computer-implemented method for testing a system for at least one requirement. The method includes: the requirement is received in machine-readable form, at least one first input variable is ascertained for the test of the system for the received requirement, a design of the system is simulated as a function of the ascertained first input variable, an output variable of the simulated system is ascertained and it is ascertained as a function of the output variable whether the system meets the requirement, it is checked whether the simulation meets a quality requirement, if the simulation meets the quality requirement and the system meets the requirement, it is checked whether a sufficient test coverage is reached for the requirement, if the sufficient test coverage for the requirement is reached, the test for the requirement is completed.
