Abstract: A vehicle includes a multi-core processor having first, second, and cores and having first and second analog-to-digital converters (ADC) associated with the first and second cores, respectively. The first and second ADC are configured to convert analog phase currents to first and second digital phase current values, respectively. The multi-core processor is configured to generate first and second rotor-angle data from digital signals representing a position of the electric machine. The processor is programmed to, via the first core, estimate a first output torque of the electric machine based on the first rotor-angle data and the first digital phase current values, via the second core, estimate a second output torque based on the second rotor-angle data and the second digital phase current values, and, via the third core, command de-activation of the electric machine in response to a difference between the first and second output torques exceeding a threshold.

Abstract: A discontinuous pulse width modulation technique is used in a controller to control an inverter that converts DC battery power to AC power to operate an electric motor, e.g., in a hybrid electric vehicle. The discontinuous pulse width modulation technique uses only one of the two zero state voltage vectors in its calculations whereas traditional pulse width modulation uses both zero state voltage vectors. The use of a single zero state voltage vector can result in one of a group of switches in the inverter remaining in a constant state during a complete duty cycle while still providing the commanded voltage vector to the electrical motor. As a result losses due to switching can be reduced.

Abstract: A method for controlling an electric motor includes receiving a first control command that is indicative of a desired motor control. A current operating condition for the motor is determined. It is then determined whether the first control command meets at least one predetermined criterion at the current operating condition. A second control command that is different from the first control command is generated when the first control command meets the at least one predetermined criterion. Generating the second control command includes determining a current value of a motor parameter, changing the parameter value, and using the changed parameter value to generate the second control command. The second control command is then used to control the motor.

Abstract: A vehicle includes a traction battery, an inverter, and a controller. The inverter includes a plurality of pairs of switches. Each of the pairs includes an upper switch that is directly electrically connected with a positive terminal of the traction battery and a lower switch that is directly electrically connected with a negative terminal of the traction battery. The controller, responsive to presence of a fault condition and during each of consecutive switching periods, deactivates all of the switches for a predetermined portion of the switching period, activates only the upper switches for another predetermined portion of the switching period, deactivates all of the switches for yet another predetermined portion of the switching period, and activates only the lower switches for still yet another predetermined portion of the switching period.

Abstract: A vehicle includes a controller configured to deactivate an inverter driving the rotor. The deactivation being responsive to respective speeds for a rotor derived from respective samples from each of a monitoring core and a current control core over a same temporal window being different by a threshold amount. The cores each generate a different number of the samples due to having different chronometric periods and the temporal window being greater than the chronometric periods.
