Control device for vehicle

A control device for a vehicle including, as prime movers, an internal combustion engine including a catalyst for exhaust gas cleaning in an exhaust passage and an electric motor supplied with power from a battery, the control device being applied to the vehicle and performing, when a warm-up request for the catalyst is present at engine start, catalyst warm-up control of retarding an ignition timing and increasing an intake air amount of the internal combustion engine to warm up the catalyst, the control device comprising a processing circuit, wherein the processing circuit is configured to execute:

• determining, when the warm-up request is present, whether polarization is likely to occur in the battery;
• and
• changing in which, in a case where determination is made that the polarization is likely to occur in the determining, both a retardation amount of the ignition timing and an amount of increment in the intake air amount in the catalyst warm-up control are increased, as compared with a case where determination is made that the polarization is unlikely to occur.
