    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 vehicle includes a motor, an alternating current (AC) power bus, a power inverter module (PIM), and a controller. The PIM includes a semiconductor die assembly with semiconductor power switches arranged in electrical parallel for delivering AC power to the motor via the bus. The controller determines an operating mode of the vehicle, selects and activates a designated one of the switches during a threshold low-current state of the PIM, and selects and activates all of the switches during a high-current state of the PIM. A PIM assembly for the vehicle includes the die assembly and controller. A method for optimizing energy efficiency of the vehicle includes providing the die assembly noted above, automatically determining the operating mode, and selecting and activating one of the switches when the operating mode corresponds to the threshold low-current state, and all of the electrical switches during the threshold high-current state of the PIM.

    摘要： A rotatable shaft is equipped with a measurement device that generates output signals corresponding to discrete angular positions of the shaft. Rotational angles of the shaft are measured for a complete rotational period. A true angular velocity of the shaft is determined. Angular velocity is calculated between contiguous pairs of the discrete angular positions. A velocity correction is determined, and a rotational angle error term is determined based upon the velocity correction.

    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.
