<p>Provided is a hybrid vehicle drive control device that reduces rattling noises that are generated by gears on an output line from a second electric motor when an acceleration operation is performed when decelerating in electric motor-based travel. When the acceleration operation is performed when decelerating in electric motor-based travel in which a brake (BK) is engaged, the engagement capacity of the brake is temporarily reduced, after which the brake (BK) is reengaged. Accordingly, when the acceleration operation is performed when decelerating in electric motor-based travel in which the brake (BK) is engaged, the brake (BK) slips during tightening of the backlash between the outer circumferential teeth of a sun gear (S2), which is connected to the second electric motor (MG2), and the outer circumferential teeth of a pinion gear (P2), which engages the outer circumferential teeth of the sun gear (S2), so the impact caused by the tightening of the backlash between the outer circumferential teeth of the sun gear (S2) and the outer circumferential teeth of a pinion gear (P2) is reduced. Consequently, the rattling noises generated by the gears on the output line from the second electric motor (MG2) are reduced.</p> |
