1. A vehicle propulsion apparatus comprising:

  • (a) a prime mover;

    (b) a secondary mover including an output controller, for activating the secondary mover;

    (c) a drive train;

    (d) a transmission, which said transmission couples the output torque produced by the said primary and secondary movers, to the drive train;

    (e) a sensor adapted for sensing the state of stress of the prime mover and producing a response related to the state of stress of the prime mover; and

    (f) a control for accepting the response and activating the secondary mover, up to the full output capacity of the secondary mover, whenever the state of stress of the prime mover is above a preselected threshold value, in which the control also includes an electrical control motor and means adapted for causing the motor to progressively depress the output controller of the secondary mover when the state of stress of the prime mover is above the preselected threshold value.
