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.
