Method for controlling an engine installed with continuously variable transmission

Patent ·
OSTI ID:6043875

This patent describes a method for controlling the rpm of an engine in a motor vehicle using a continuously variable transmission. The transmission has a driving pulley which consists of: 1.) A fixed member and a movable member, the movable member being actuated by a hydraulic cylinder to form a v-shaped opening between the movable member and the fixed member; 2.) A driven pulley mounted on an output shaft with another fixed member and another movable member; 3.) Another movable member is similarly actuated by another hydraulic cylinder to form another v-shaped opening between the other movable member and the other fixed member; and 4.) an endless belt member spanning the pulleys so that different transmission ratios can be obtained.
