ABSTRACT:
A vehicular gas turbine engine power system includes an engine, an automatic clutch, a service clutch and an infinitely variable transmission coupled successively along a power train. A vehicle control system controls engine speed, transmission ratio and automatic clutch engagement in response to operator selected ground speed and engine speed commands as well as other vehicle conditions. The vehicle control system operates in a manual mode to maintain engine speed as commanded by an operator or in an automatic mode to maintain an engine speed which will minimize fuel consumption. The transmission ratio is controlled for fixed rate vehicle acceleration toward a commanded speed if sufficient power is available. Otherwise ground speed is cut back to match required power with available power. However, ground speed cut back is limited as a safety feature and disengagement of the automatic clutch prevents engine stall when the engine becomes overloaded.
