Abstract
A control system for a continuously variable transmission, in which a responsiveness and a generation of an excessive force in a steady state are compatible. The control system makes a belt slippage prevention and a fuel economy improvement compatible by controlling a CVT with one of two parameter values: the first parameter value which is determined from an engine RPM and an accelerator opening, i.e., a torque information quick in the output timing but poor in the precision and which indicates the engine output torque; and the second parameter value which is determined from a fuel injection rate, i.e., a torque information excellent in the precision but slow in the output timing and which indicates the engine output torque.
