Methods and apparatus are provided for monitoring an achieved motor torque produced by an electric motor. The method includes determining the achieved motor torque based on a rotor position of the electric motor and a phase current of the electric motor when the motor speed is not greater than a first pre-determined threshold, determining the achieved motor torque based on a loss-compensated power supplied to the electric motor when the motor speed is greater than the first pre-determined threshold, comparing the achieved motor torque with the torque command, and indicating a fault when the achieved motor torque is not within a pre-determined margin of the torque command.

A diagnostic system for a hybrid vehicle comprises a motor control module and a fault diagnostic module. The motor control module controls torque output of an electric motor having a predetermined number of phases. The fault diagnostic module determines a position of a rotor of the electric motor, aligns the rotor with a phase angle of one of the phases, selectively diagnoses a fault based on a current of at least one of the phases, and selectively disables the electric motor based on the diagnosis.

A method is provided for detecting an insufficient or missing phase current in a permanent magnet synchronous motor, and includes determining a composite vector position of a combined three-phase phase current with respect to a stationary portion of the motor, and assigning a sector to the position. The method includes comparing the phase current to a calibrated threshold current corresponding to the sector, and executing a response when the absolute value is less than the threshold. A vehicle includes an energy storage device (ESD), a motor/generator configured as a permanent magnet synchronous motor, a voltage inverter, and a bus for conducting DC current from the ESD to the inverter. A controller detects an insufficient phase current, determines a current vector position of the three-phase AC, assigns a sector to the position, and executes a response when an absolute value of the phase current is less than a calibrated threshold.

A diagnostic system for a hybrid vehicle comprises a processor module and a motor control module. The processor module outputs a seed value. The motor control module controls torque output by an electric motor of the hybrid vehicle, receives the seed value, generates a final key value based on the seed value, and outputs the final key value to the processor module.

A compressed binary schema representation object for metadata processing and a related method are provided. The compressed binary schema representation provides savings in bandwidth and processing requirements as compared to textual schema representations. The binary schema representation makes it possible to select and decode only desired schema elements without the need to parse the entire schema.

Both an XML schema and XML instance data as correspond to an XML document are provided (). The XML schema is processed () apart from the XML instance data to provide resultant compressed XML schema data while the XML instance data is processed () to provide a corresponding XML instance table. The latter is compressed () to yield a resultant compressed XML instance table. Following receipt of such items, the compressed XML instance table is decompressed () to provide a resultant XML instance table with the latter being used (), along with the XML schema, to facilitate a corresponding XML document process.
