PROBLEM TO BE SOLVED: To provide a drive control device of a hybrid vehicle which reduces shock upon clutch engagement by suppressing fluctuation in the travelling state of the vehicle during shift control of the hybrid vehicle in which a power of an engine is transmitted to the wheel side via a clutch and a transmission.SOLUTION: When a shift instruction (up-shift instruction or down-shift instruction) occurs, a clutch 16 is opened, a gear range of a transmission 13 is switched and, thereafter, shift control for engaging the clutch 16 is executed. An axle rotation speed control for controlling the rotation speed of an MG 12 to set the rotation speed of the axle 18 connected with the MG 12 such that electric power can be transmitted to a target rotation speed is executed during shift control and, thereby, it is suppressed that the travelling state (for example, vehicle speed and acceleration) of the vehicle is fluctuated during shift control. Thereby, even when a torque difference between an engine 11 side and the transmission 13 side (torque difference between an input side and an output side of the clutch 16) is generated during the opening of the clutch 16 upon the shift control, it is suppressed that the travelling state of the vehicle is fluctuated upon engagement of the clutch 16. |
