System and method of compensating heating performance of continuously-variable-transmission-equipped vehicle

A system for compensating a heating performance a motor vehicle with a CVT, wherein the system includes a coolant-temperature sensor for sensing an engine-coolant temperature, and a transmission ECU electronically linked to the CVT and the coolant-temperature sensor, wherein the transmission ECU is so programmed as to: determine whether or not heating-performance compensation is required in accordance with at least the engine-coolant temperature; obtain, if it is determined that heating-performance compensation is required, a target input rotation of the CVT in such a way as to avoid input rotation of the CVT from being below a lower limit value determined to restrain degradation of the drivability and shift quality while compensating the heating performance every vehicle speed; and shift-control the CVT in accordance with the target input rotation.
