摘要： A method for checking the plausibility of a torque of an electric machine, calculated on the basis of a machine model, in which a first value of an electromagnetic power of the electric machine is determined from the calculated torque and a rotational speed of the electric machine. Stator current components and stator phase voltage components are calculated from the stator currents and the stator phase voltages with respect to a reference system, which is fixed in relation to the stator. A second value of the electromagnetic power of the electric machine is determined from the stator current components and the stator phase voltage components. If a deviation of the first value of the electromagnetic power of the electric machine from the second value exceeds a predefined power threshold value, the torque of the electric machine, calculated on the basis of the machine model, is classified as implausible.

摘要： The invention relates to a method and device for determining or checking the plausibility of an offset angle between an assumed orientation and an actual orientation of a rotor (20) relative to a stator (10) in an electric machine (1). In the method, the electric machine is first controlled in a quasi zero-current state, in which substantially no current should flow in the windings of the electric machine. Then a voltage indicator that specifies the direction of a voltage controlled in the electric machine during the quasi zero-current state is determined and subsequently transformed into a coordinate system that is fixed with respect to the rotor. The offset angle or an angle error with respect to a previously assumed, calibrated offset angle can be determined on the basis of the transformed voltage indicator.

摘要： A method for operating an electrical network, in particular of a hybrid motor vehicle, the network having at least one electrical accumulator, in particular a high-voltage accumulator, at least one electric machine, and at least one inverter controlling the electric machine, the electrical accumulator being electrically disconnected from the network when a malfunction is detected and the inverter being switched to a short-circuit operating mode when a specifiable voltage limit of a network voltage of the network is subsequently exceeded. There is a provision for switching power semiconductors of the inverter in such a way that the driven electric machine induces a voltage and provides it via free-wheeling diodes on the electrical network and the induced voltage is used for operating the electric machine as a generator such that a specifiable network voltage is set by the electric machine.

摘要： In a method for determining a power limiting value for an electric machine in a vehicle, the electric machine being assigned an energy storage device, an intermediate power value is calculated from a maximally allowable current of the energy storage device and an instantaneous voltage. A corrected intermediate power value is determined by adding at least one power loss to the intermediate power value. A first correction value is determined for reducing the absolute value of the corrected intermediate power value if an instantaneous power of the energy storage device is greater than the absolute value of the calculated intermediate power value. The power limiting value is determined by superimposing the first correction value on the corrected intermediate power value.
