Abstract
A vehicle includes a transmission between an engine and a drive wheel and includes a differential mechanism (planetary gear mechanism) between the engine and an engagement device (transmission). A controller (ECU) included in the vehicle calculates a variation rate in the whole rotation energy of the planetary gear mechanism when it is in the inertia phase of a shift. The ECU increasingly corrects an engine generated power and decreasingly corrects a transmission transfer power when the variation rate is higher than 0. The ECU decreasingly corrects the engine generated power and increasingly correct the transmission transfer power when the variation rate is lower than 0.
