Control device for hybrid vehicle

A control device for a hybrid vehicle, the hybrid vehicle comprising an engine, which is adapted to allow a partial cylinder deactivation operation, a motor, which is capable of power generation, and driving wheels, the output power of at least one of the engine and the motor being transmitted to the driving wheels for driving the hybrid vehicle;

• the control device comprising:
• a battery device sending energy to and receiving energy from the motor;
• a temperature measuring section for measuring the temperature of the battery device;
• a control section which is adapted to execute a warming control operation for the battery device when the temperature of the battery device measured by the temperature measuring section is equal to or lower than a first predetermined value;
• and
• a determination section for determining whether the partial cylinder deactivation operation is permitted for the engine depending on the running state of the engine, wherein
• the control section is further adapted to execute a vibration control operation for the engine by operating the motor so as to reduce vibration of the engine when it is determined by the determination section that the partial cylinder deactivation operation is permitted for the engine, and to perform the warming control operation for the battery device by executing a vibration control operation for the engine.
