ABSTRACT:
When an operator takes his foot from an accelerator pedal, a returning speed of the accelerator pedal is calculated from a signal of an accelerator sensor. In case where the returning speed is larger than a reference value, it is judged that the operator intends to decelerate a vehicle with an engine brake applied and the speed ratio of the continuously variable transmission is fixed to a value at the moment when the operator releases the accelerator pedal. As a result, the vehicle decelerates while the engine brake is exerted. In case where the returning speed is smaller than the reference value, it is judged that the operator intends to run the vehicle by inertia and the speed ratio of the transmission is changed to a speed ratio on an overdrive side so as to allow a coasting operation.
