Abstract: In a control apparatus for a hybrid vehicle which is able to travel under the driving force from at least one of an internal-combustion engine E and a drive motor connected to the internal-combustion engine, when an FI/AT/MGECU and a MOTECU execute motor damping which generates a torque for suppressing the torque vibration of the internal-combustion engine, in the motor M, the MOTECU corrects a motor torque calculating battery terminal current value obtained by multiplying an input-output current ABAT of the battery, by an offset value corresponding to the motor damping, and executes zero power control based on the corrected motor torque calculating battery current value. As a result, the input and output power of the power storage unit are accurately balanced and overcharge or overdischarge of the battery based on the input-output current ABAT of the battery including errors due to the damping control or the motor torque calculating battery current value, is avoided.
