Abstract
A control device is disclosed which can obtain increased fuel economy performance depending on a kind of fuel in a vehicle having an internal combustion engine and an electric motor when the kind of fuel supplied to the internal combustion engine is altered. A determining vehicle speed (V1) and determining output torque (T1), representing a boundary value with which a step-variable control region and a continuously variable control region of a shifting mechanism (10) are demarcated, are altered such that the higher the mixing ratio of ethanol, the lower will be the determining vehicle speed (V1) and determining output torque (T1). Therefore, the determination is made whether to operate a first electric motor (M1) depending on the mixing ratio of ethanol, making it possible to obtain increased fuel economy performance in line with the mixing ratio of ethanol.
