Abstract:
An improved method for operating a vehicle with a combination, of a continuously variable transmission and an electric motor, powered by a mobile electrical storage device, with the steps of supplying electrical power to said combination from said storage device, transmitting mechanical power between said electric motor and a drive wheel of said vehicle, and varying a speed ratio between said electric motor and said drive wheel in a continuous manner, the improvement comprising:supplying electrical potential for direct current to said motor,varying the amount of electrical potential supplied to said motor in a continuous manner, andvarying a radial distance from axis of rotation a power transmission belt rides upon a pulley to vary said speed ratio between said electric motor and said drive wheel in a continuous manner in response to motor speed and in response to motor load by communication of a biasing arrangement.
