Primary clutch electronic CVT

A vehicle including:

• a chassis;
• a ground engaging mechanism configured to support the chassis;
• an engine supported by the chassis;
• a continuously variable transmission driven by the engine, the continuously variable transmission including a first clutch, a second clutch, and a belt coupled to the first and second clutches, the first clutch being adjustable with an actuator to modulate a gear ratio of the continuously variable transmission;
• a throttle valve configured to regulate a speed of the engine;
• at least one controller including engine control logic operative to control a position of the throttle valve and transmission control logic operative to control a position of the first clutch of the continuously variable transmission, the at least one controller being operative to detect an acceleration rate of the vehicle;
• an engine speed sensor in communication with the at least one controller for detecting a speed of the engine;
• a throttle operator device moveable by an operator and including a position sensor in communication with the at least one controller, the position sensor being configured to detect a position of the throttle operator;
• and
• an operator input device in communication with the at least one controller configured to adjust a clutch control variable provided to the at least one controller, the transmission control logic being operative to calculate a target engine speed based on the clutch control variable, the transmission control logic being operative to calculate a target position of the first clutch of the continuously variable transmission based on the target engine speed, the detected acceleration rate of the vehicle, and the detected engine speed;
• and
• the transmission control logic being operative to control the actuator to move the first clutch from an initial position to the target position, the transmission control logic further determining a target velocity of the first clutch based on the vehicle acceleration rate for a movement of the first clutch from the initial position to the target position, wherein the transmission control logic calculates the target position of the first clutch of the continuous variable transmission further based on the target velocity.
