ABSTRACT:
Transmission and engine control means for a vehicle wherein the engine is connected through at least one friction clutch to a transmission having a positively geared power train therethrough. A low speed governor is provided to sense an engine speed at or shortly below idling speed and functions to increase fuel supply to the engine as same is lugged down for maintaining, within the capacity of the engine, at least said selected minimum speed. Further, means are provided responsive to the position of the throttle control, such as the accelerator pedal, for modulating the engagement pressure of said clutch in response to the position of such throttle control, progressive opening of the throttle effecting progressive increase in the torque transmitting capacity of the clutch, whereby the torque transmitting capacity of the clutch is under all throttle settings maintained at a value a little greater than the load torque normally applied thereto at such throttle setting. If desired, further means may be provided for deactivating and disengaging said transmission clutches entirely when the throttle is in its idling position and the vehicle is either at standstill or at a speed below a selected value.
