ABSTRACT:
A control system for hybrid vehicles in which an electric prime mover is connected to an output shaft through a transmission, comprising: a running state judging means for judging whether or not a downshifting is being carried out to increase speed change ratio of the transmission while a vehicle is coasting; a creep torque lowering means for lowering creep torque generated by the electric prime mover, in case the running state judging means judges that the downshifting is being carried out; a speed change termination judging means for judging a termination of the downshifting; and a creep restoring means for raising the lowered creep torque to the previous level subsequent to the termination of downshifting, at a timing which is delayed in comparison with a timing when the torque is raised due to a torsional vibration arising from the downshifting.
