Abstract
A hybrid vehicle control apparatus () provided with: an internal combustion engine (); a rotating electrical machine (MG); and a power transmission mechanism () which is provided with a plurality of rotational elements each having a play in its rotational direction and which can transmit a torque between a drive shaft coupled with an axle and the internal combustion engine or the rotating electrical machine, the hybrid vehicle control apparatus including: a judging device () for judging whether or not an input/output torque of the rotating electrical machine to the drive shaft crosses an avoidance area, which is set as generating a rattle caused by the play in the power transmission mechanism in a process that the input/output torque converges to a target torque; and a reducing device () for reducing a crossover time as a time required for the input/output torque crossing the avoidance area in a case where the input/output torque is judged to cross the avoidance area, with respect to a reference time as a time required for the input/output torque crossing a torque area corresponding to the avoidance area in a case where the input/output torque does not cross the avoidance area.
