摘要： Methods and systems are provided for monitoring an automotive electrical system including an inverter having at least one switch. First and second voltage commands corresponding to respective first and second components of a commanded voltage vector on a synchronous frame of reference coordinate system are received. A plurality of duty cycles for operating the at least one switch are calculated based on the first and second voltage commands. First and second actual voltages are calculated based on the plurality of duty cycles. The first and second actual voltages correspond to respective first and second components of an actual voltage vector on the synchronous frame of reference coordinate system. An indication of a fault is generated based on the difference between the first components of the commanded voltage vector and the actual voltage vector and the difference between the second components of the commanded voltage vector and the actual voltage vector.

摘要： Methods and systems are provided for modeling temperature characteristics of components in a system such as a power module for a hybrid or electric vehicle. A power dissipation value is calculated for each of the components in the system. A first filter is applied to the power dissipation value associated with a selected component to determine its estimated temperature. For each of the neighboring components located adjacent to the selected component, a cross-coupling temperature is estimated by applying other filters to each of the power dissipation values for the neighboring components. The estimated temperature of the selected component and the estimated cross-coupling temperatures for each of the neighboring components can then be added to thereby estimate the operating temperature for the selected component. Further, the operation of the system may be adjusted if the operating temperature determined for the selected component exceeds a threshold value.
