ABSTRACT:
A continuously variable belt and sheave drive mechanism for use with an internal combustion engine in an automotive vehicle driveline including a simplified valve system that responds to control commands from a microprocessor that receives input data from engine, turbine and output shaft speed sensors, an engine throttle position sensor and a sheave position sensor as well as other driveline variables so that the operating characteristics of the transmission are matched to the speed torque characteristics of the engine to produce improved driveline efficiency and performance while permitting the engine speed to be related functionally to the throttle position as well as vehicle speed and permitting engine speed to increase when rapid acceleration is desired while minimizing changes in engine speed for small throttle position variations.
