摘要： There is provided a failure determination system for a continuously variable transmission of a belt type, which is capable of determining failure of control valves for performing speed varying operation, and enhancing maintainability. An ECU controls a transmission ratio of the transmission to a fixation-determining LOW-side range when the vehicle is standing. When the transmission ratio during stoppage of the vehicle is within a stop-time OD-side range if engine torque≧OD-time DR-side reference torque and at the same time the transmission ratio

摘要： In a power transmission, which adjusts and transmits the rotational output of an engine by the engagement control of a starting clutch 5, the rotational speed Ne and the suction negative pressure Pb of the engine are measured while the starting clutch is being actuated from a disengaged condition to an engaged condition with the engine being operated under a constant operational condition. An engagement-control value is calculated for the starting clutch when there is a change in the rotational speed and the suction negative pressure being measured, and the engagement-control value calculated is stored as an initial control value for starting an engaging action of the starting clutch. This initial control value is used for controlling the engagement of the starting clutch.
