PROBLEM TO BE SOLVED: To provide a control system of a hybrid vehicle capable of suppressing a variation in an engine speed when engine modes are changed from torque control to engine speed control.SOLUTION: When a vehicle is traveling in an HEV mode in which an engine 1 and a motor generator 2 that are a driving source are driven, a control system switches a first control mode, in which engine torque control and motor number-of-rotations control are implemented, and a second control mode in which engine speed control and motor torque control are implemented. The control system includes a correction torque arithmetic unit 20c that computes an engine torque correction value &Dgr;Te on the basis of a second clutch input command torque Tunder the first control mode, and a second clutch input actual torque Tunder the first control mode, and an engine speed control unit 21a that uses the engine torque correction value &Dgr;Te to correct an initial value of an engine speed control engine torque command value Te1to be provided at the time of initiating engine speed control for the engine 1 when modes are changed from the first control mode to the second control mode. |
