Abstract
A control system for a hybrid vehicle configured to generate a required power continuously even if a large power is required frequently. An operating mode of the hybrid vehicle is selected from HV mode and EV mode, and in the hybrid vehicle, a drive power established by generating maximum output power of the engine is smaller than a drive power established by supplying a maximum electric power to the motor from the electric storage device. A controller is configured to shift the operating mode from the EV mode to the HV mode when an SOC level of a battery falls below a threshold level, and to raise the threshold level when a required running condition in the electric vehicle mode is a condition that cannot be achieved by the engine without operating the motor given that the hybrid vehicle is propelled in the hybrid mode.
