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.
