PROBLEM TO BE SOLVED: To reduce torque shock when operation is switched between full- cylinder operation and rest-cylinder operation by controlling the electric motor such that the torque difference of engine torque output from respective operations is canceled by drive assist and regeneration by the electric motor. SOLUTION: If an engine is in a rest-cylinder operation range [if outside the rest-cylinder operation range] a full-cylinder torque TEN and a rest-cylinder torque TES corresponding to present NE and TH are retrieved (S3), [S13] from a full-cylinder torque map and a rest-torque map having an engine revolution speed NE and a throttle opening TH as parameters. Next, a cross point opening degree THCP corresponding to the present NE is retrieved (S4), [S14] from a cross point opening degree map having NE as the parameter. If TH > THCP (S5), [S15], control is implemented such that an engine torque difference is compensated by assist [regeneration] of an electric motor (S6), [S16]. If TH <= THCP (S5), [S15], control is implemented such that the engine torque difference is compensated by regeneration [assist] mode of the electric motor (S7), [S17]. |
