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 vehicle includes an accelerator pedal, a brake pedal, an electric machine, friction brakes, and a controller. The electric machine is configured to propel the vehicle and to brake the vehicle during regenerative braking. The friction brakes are configured to brake the vehicle. The controller is programmed to, responsive to an operator selection of a one-pedal drive mode, decrease vehicle speed via regenerative braking in response to releasing the accelerator pedal. The controller is further programmed to transition the vehicle to an inhibit state in which the friction brakes are applied to prevent vehicle creep in response to receiving an automated signal to disable the one-pedal drive mode and vehicle speed becoming zero while the one-pedal drive mode is selected.

Abstract: A vehicle includes a controller having a microcontroller and a monitoring processor. The controller includes a bus transceiver for communicating on an external communication bus. The controller is configured such that each of the microcontroller and the monitoring processor can output a transmit data signal to the bus transceiver. The source of the transmit data signal is selected as the output of the monitoring processor responsive to evaluating the microcontroller as being inoperative.
