The present invention provides a control device for a hybrid vehicle capable of avoiding an excessive decrease in engine speed and deterioration of vibration caused by rapid deceleration in a direct connection mode. The sudden deceleration operation is detected when the direct connection mode is set (step S1). If the sudden deceleration operation is detected, the control is executed to release theone of the first engagement mechanism and the second engagement mechanism that are engaged in the direct connection mode, the torque shared by the engagement mechanism due to the inertia torque becomes smaller (step S3-S6), the direct connection mode is switched to one of the high mode and the low mode, and the inertia torque is the inertia torque of the motor that is generated with the rapid deceleration operation. 本发明提供能够避免直接连结模式下的急减速引起的发动机转速的过度的降低、振动恶化的混合动力车辆的控制装置。对在设定着直接连结模式的状态下进行了急减速操作这一情况进行检测(步骤S1)，在检测到急减速操作的情况下，执行使在直接连结模式下接合着的第1接合机构和第2接合机构中的、因惯性转矩而导致接合机构所分担的转矩变为更小的某一方的接合机构释放的控制(步骤S3～S6)，从直接连结模式切换为高模式和低模式中的某一方的
