摘要： 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.

摘要： A control system for a motor including a rotor comprises a sensorless sensor module that includes a saliency-based estimator module that generates a first rotor position signal based on saliency and a back electromotive force (emf) estimator module that generates a second rotor position signal based on back emf. A selector selects the first rotor position signal for rotor speeds below a first rotor speed and the second rotor position signal for rotor speeds above the first rotor speed. A rotor position sensor senses a position of the rotor and generates a third rotor position signal. A fault detection module senses faults in the rotor position sensor and outputs the third rotor position signal when a fault is not detected and one of the first and second rotor position signals when the fault is detected. An indirect field oriented control (IFOC) system controls the motor based on a selected one of the first, second and third rotor position signals.

摘要： A control system and method to determine position of a rotor relative to a stator for a synchronous multipole electrical machine is presented, including one for application on a fuel/electric hybrid powertrain for a vehicle. The machine includes a stator, a rotor, and a rotor position sensing mechanism. The control system controls the electrical machine, in conjunction with an electrical storage device and an inverter, using algorithms and calibrations which derive a rotor position based upon a sensorless position sensing technique, and determine an offset from a sensed rotor position. Electrical output from the inverter to the machine is controlled based the offset, which is stored non-volatile memory. A rotor position is derived based upon a sensorless position sensing technique during initial machine operation after startup of the machine, and includes operation in a torque-generative mode and in an electrical energy-generative mode.

摘要： An improved transmission shift pattern control that preserves the attributes of a selected base shift pattern while dynamically adjusting the high throttle shift thresholds based on a measure of vehicle loading. Heavy vehicle loading is detected by recognizing a pattern of high engine throttle and lower than expected vehicle acceleration, and the high power shifting thresholds are dynamically adjusted based on the detected loading to automatically provide aggressive shifting in a heavily loaded vehicle without producing excessive shift cycling in a normally or lightly loaded vehicle. A throttle timer is used to detect a condition of sustained high throttle operation, and under such condition, an acceleration timer determines the duration of lower than expected acceleration. If the determined duration exceeds a threshold, a shift pattern override is activated until the acceleration rises above an exit threshold. The severity of the loading condition may be determined with multiple acceleration timers used to activate successively more aggressive shift pattern overrides.
