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.

Control system and method for continuously variable transmission

An in-cylinder injection type internal combustion engine, which includes a main fuel injection control unit that drives a fuel injector to inject fuel directly into a combustion chamber, is provided so that premixed combustion or stratified charge combustion takes place depending upon operating conditions of the engine. The engine further includes an additional fuel injection control unit that drives the fuel injector to inject additional fuel during an expansion stroke after the fuel injector is driven by the main fuel injection control unit, when it is necessary to increase the temperature of a catalyst provided in an exhaust passage for purifying exhaust gas. An exhaust manifold includes an exhaust chamber, in which the exhaust gas remains, and the additional fuel that is left unburned is re-burned in the exhaust chamber.
