Abstract
A hybrid vehicle includes a generator driven by an internal combustion engine, a battery charged by the generator and an electric motor driven by the generator and the battery. A drive system transmits the output of the motor to wheels of the vehicle. When, and only when, adequate power cannot be provided by the motor to the wheels because of a fault, an emergency drive indicator issues a command to a power transmitting mechanism, which is responsive only to the command signal to directly transmit the output of the engine to the drive system.
