Abstract

A control system for hybrid vehicle for extending a possible travelling distance of the vehicle in the event of clutch failure is provided. The control system is configured to select a first drive mode in which the vehicle is powered by an engine in case an estimated torque transmitting capacity of the clutch in trouble is larger than a first threshold value, and to select a second drive mode in which the vehicle is powered by a motor in case the estimated torque transmitting capacity of the clutch in trouble is smaller than the first threshold value. The control system is further configured to reduce an engine torque to be smaller than the estimated torque transmitting capacity of the clutch in case the first drive mode is selected.
