A method for providing a reliable time signal. In the method, a first time signal from a first time source and a second time signal from a second time source are received and evaluated by an arrangement, the first time source and the second time source being independent of each other, the arrangement including a first unit in the arrangement which fulfills an observer and comparator function, the two time signals are compared with each other and a detected deviation between the two time signals is evaluated, and the reliable time signal is output on the basis of this evaluation.

Method for transitioning a vehicle between different modes according to agreement and deviations between time signals of different time sources

The invention relates to a method () for external monitoring of power electronics (), wherein the power electronics () are actuated by means of first control electronics () and the method () is carried out by independent, second control electronics (). The method comprises the following steps: determining () a parameter (P); determining () the difference (D) of between the determined parameter (P) and a target value (S); actuating () the power electronics () if the amount of the difference (D) exceeds a threshold (G).

In a method for actuating at least one actuator, two control units and a selection logic are provided, and each of the control units is designed to influence the actuator. Each of the control units performs a self-diagnosis, and each of the control units generates at least one activating signal as a function of the self-diagnosis. The activating signal indicates which of the control units is to be activated. The selection logic activates one of the two control units for influencing the actuator as a function of the activating signals.

The invention relates to a method () for monitoring a torque of an electric motor (), in particular for application in a motor vehicle, wherein the electric motor () is supplied with electric current (IS, IS, IS) in multiple phases. A first torque value (M) of the torque generated by the electric motor () is determined () on the basis of the electric output of the electric motor () and a detected rotational speed (n) of a rotor of the electric motor (). A second torque value (M) is determined on the basis of at least one measured phase current (IS, IS, IS) and a rotational position of the rotor, and the two determined torque values (M, M) are compared () to one another for plausibility checking.
