PURPOSE:To heighten the rotating speed of an engine by compensating the speed ratio to the engine rotating speed increase side with a lowering of the temperature of a stepless speed change gear. CONSTITUTION:As the temperature Toil of working fluid of a belt stepless speed change gear (CVT)14, the target speed is compensated to decrease so that the rotating speed of an engine is compensated to the increase side. Thus, in the case where the viscosity of working fluid of CVT14 is high due to low temperature, and the frictional resistance of the CVT14 is large, the running performance is maintained by increasing the rotating speed of the engine. |
