Abstract

See full text

For each engine operation state to which a variable cylinder engine can be switched, a fuel consumption amount to be consumed to generate a driving force required to maintain a current traveling state of a vehicle for each of a current gear and a new gear after a possible shift-up is calculated. An automatic shift control of shifting up to the new gear is performed in a condition that a calculated fuel consumption amount of the new gear after the possible shift-up is smaller than a calculated fuel consumption amount of the current gear. In this way, the fuel consumption amount can be optimally reduced and the shift control can be performed without degrading the traveling performance, even in the vehicle equipped with the variable cylinder engine.
