ABSTRACT:
A control system for a hybrid vehicle that is capable of absorbing an inertial force which is generated during shifting of a stepped transmission. During shift control of the stepped transmission by a shift control device and before the shift control is completed, a during-shift drive control element controls a driving force which is output from a second drive unit such that a total driving force which is output from first and second drive units to the drive wheels equals a driver request output. Further, the during-shift drive control elements executes control so as to reduce a difference between the total driving force output to a drive wheel and the driver request output based on a change in a transmission force of the stepped transmission caused by a switch-over between a first brake and a second brake. Moreover, in an inertial phase of the switch-over between the first brake and the second brake, the during-shift drive control means controls a driving force of a second motor so as to absorb an inertial force which is generated by change in a rotational speed of the second motor with respect to the rotational speed of the drive wheel.
