Abstract
An apparatus provides protection to an electric traction motor of a vehicle. The vehicle has a first powertrain and a second powertrain. The first powertrain includes an engine and it is coupled with a first set of road wheels. The second powertrain includes the electric traction motor and it is coupled with a second set of road wheels. The apparatus comprises a revolution speed sensor operatively associated with the electric traction motor. The apparatus also comprises at least one controller. The controller includes control logic for modifying operation of the vehicle in response to monitoring the revolution speed sensor to restrain the vehicle speed from increasing in such a manner as to limit revolution speed of the electric traction motor to revolution speed values below an allowable upper revolution speed limit.
