Abstract
A hybrid electric vehicle 10 having a propulsion system 12 which includes an internal combustion engine 14, a generator/motor 16 and an electric motor or a “traction inverter module” 18 which cooperatively provide power to the drive train 28 of vehicle 10. Vehicle 10 includes a controller 44 which is effective to detect whether any faults are present within any of the torque providing subsystems (e.g., in engine 14, generator/motor 16 and/or motor 18), and if one or more faults is. present, to provide a limited operation strategy which allows the vehicle to be driveable by use of the remaining operational subsystem(s).
