PROBLEM TO BE SOLVED: To allow shifting time of a hybrid vehicle in which engine power is transmitted through a clutch and a transmission to wheels to be reduced and to allow shock during shift control to be reduced.SOLUTION: A drive control device for a hybrid vehicle is provided which, when a gear shift instruction (an upshift command or a downshift command) is generated, releases a clutch 16 to switch a gear position of a transmission 13 and then performs a shift control for engagement of the clutch 16. At that time, the drive control device performs a MG (Motor Generator) rotational speed control by which the rotational speed of a MG 12 is feed-back controlled so that rotational speed of an engine 11 accords with target rotational speed (rotational speed slightly higher or slightly lower than input shaft rotational speed for example) based on the input shaft rotational speed of the transmission 13 while releasing the clutch 16. This allows a difference in rotational speed between the engine 11 side and the transmission 13 side (a difference between the engine rotational speed and the input shaft rotational speed of the transmission 13) to be quickly reduced while releasing the clutch 16 and allows engagement of the clutch 16 to be started early. |
