Hybrid vehicle control device

A control device for a hybrid vehicle comprising:

• a starting clutch disposed between a drive source and drive wheels;
• a slip drive mode in which the vehicle travels with the drive source placed under a rotation speed control at a higher rotation speed than an output side rotation speed of the starting clutch while performing a slip control on the starting clutch to achieve a value in accordance with a target drive torque set based on an accelerator pedal opening;
• an engagement drive mode in which the vehicle travels with the drive source placed under a torque control in accordance with the target drive torque set based on the accelerator pedal opening while fully engaging the starting clutch;
• and
• a clutch control mechanism that controls the starting clutch transfer torque capacity at a time of the slip control, wherein
• the clutch control mechanism, when transitioning in mode from the slip drive mode to the engagement drive mode, calculates a transfer torque capacity that ensures a same output shaft angle acceleration between a slip state and an engaged state of the starting clutch, and deducts from this transfer torque capacity inertia components at a side of drive source to set the starting clutch transfer torque capacity at the slip state.
