Abstract: A resolver disposed to monitor a rotatable member is described, along with an associated method for evaluating an output signal therefrom. The method for monitoring the resolver includes supplying an excitation signal to the resolver, and monitoring, at an oversampling rate, first and second output signals from the resolver. An oversampling routine is executed to determine averages of the first and second output signals from the resolver. A demodulation angle error is determined based upon the first and second output signals from the resolver, and provided as feedback. A position of the resolver is also determined based upon the first and second output signals from the resolver.

Abstract: A method for estimating a magnet temperature of a rotor magnet within a rotary electric machine includes, while a rotor of the electric machine is stationary, injecting a high-frequency voltage component onto a control voltage of the electric machine, via a controller, to generate an adjusted voltage command, and extracting a high-frequency component of a resulting current as an extracted high-frequency component. The method also includes calculating an inductance value of the electric machine using the extracted high-frequency component of the resulting current. The magnet temperature is estimated using the calculated inductance value and an angular position of the rotor. The method includes controlling an operation of the electric machine using the estimated magnet temperature. An electric powertrain uses the electric machine and controller noted above.

Abstract: A method of exchanging data in a real-time operating system, between a primary core and a secondary core in a multi-core processor, includes executing a primary path via the primary core and executing a secondary path via the secondary core. The primary path is configured to be a relatively faster processing task and the secondary path is configured to be a relatively slower processing task. The method includes devising a freeze in process flag to have a respective flag status set and cleared by the primary path. The method includes devising a data frozen flag to have a respective flag status set and cleared by both the primary and the secondary paths. A component that is operatively connected to the multi-core processor may be controlled based at least partially on a difference between primary and secondary sets of calculations executed by the primary and secondary cores, respectively.

Abstract: A method for operating an electric machine of a ground vehicle includes periodically determining an aging parameter based upon a temperature of the electric machine and periodically determining a short-term aging effect based upon the periodically determined aging parameter. A long-term aging effect is determined based upon the short-term aging effect. A short-term temperature adjustment is determined based upon the short-term aging effect and a long-term temperature adjustment is determined based upon the long-term aging effect. A temperature-based derated motor torque is determined based upon the long-term temperature adjustment and the short-term temperature adjustment. Operation of the electric machine is controlled responsive to an operator command for torque based upon the temperature-based derated motor torque.

Abstract: A system for controlling operation of a vehicle having a power inverter module includes an alternating current (AC) power bus coupled to the power inverter module. The AC power bus has a plurality of busbars for conducting an AC current having multiple phases. The AC power bus is coupled to a stator in an electric motor configured to generate torque to propel the vehicle. A controller is adapted to determine an estimated temperature of the AC power bus for the multiple phases based on a plurality of factors. The plurality of factors includes an oil flow rate of a motor oil and a coolant flow rate of an inverter coolant that are in respective direct or indirect thermal contact with the plurality of busbars. The controller is adapted to control operation of the vehicle based in part on a highest one of the estimated temperature of the multiple phases.

Abstract: A method, apparatus, and control system are described for operating a multiphase motor drive system including a rotary electric machine and an inverter. An AC choke filter is arranged proximal to output leads from the inverter. A reference temperature associated with the AC choke filter is determined along with an operating point of the electric machine. Operation of the inverter is controlled based upon a temperature of the AC choke filter, the reference temperature, and an operating point of the electric machine. This includes modifying a switching frequency and a PWM type in a manner that reduces the AC choke filter temperature by reducing the occurrence of switching events to protect the AC choke filter based on temperature feedback.

Abstract: A torque system includes a DC power device, a polyphase electric machine, a contactor pair, a power inverter module (PIM), and a controller. The PIM connects to the power device via the contactor pair and directly connects to the electric machine. The controller executes a method to control a fault response under a fault condition resulting in opening of the contactor pair and a polyphase short condition. The controller calculates a back EMF of the electric machine and transmits switching control signals to semiconductor switches of the PIM to transition from the polyphase short condition to a polyphase open condition only when the calculated back EMF is less than a calibrated value and a voltage rise on a DC side of the PIM is less than a calibrated voltage rise. A vehicle includes the DC power device, road wheels, electric machine, PIM, and controller.
