Abstract
A continuously variable transmission that can provide a sufficient engine braking during a downhill running time with neither complicating the control nor inviting an increase in the program capacity is established. In a gear ratio control system for gear ratios in the continuously variable transmission coupled to an engine, setting means to set a target speed of an input unit of the continuously variable transmission during the downhill running time on the basis of a target output of the engine. Control means controls the gear ratios of the continuously variable transmission so that the real speed of the input unit may become the target speed of the input unit
