Abstract
A vehicle control system is provided to improve a response of shifting operation of a drive mode while avoiding a shortage of drive force. The control system is applied to a hybrid vehicle having an internal combustion engine and two motors, and configured to select a drive mode from a mode where the vehicle is powered by the engine and a mode where the vehicle is powered by at least one of the motors while stopping the engine. The control system predicts a fact that the engine is expected to be started based on a detection value representing a running condition of the vehicle, during propulsion of the vehicle by the two motors while stopping the engine; shifts a drive mode to a mode where the vehicle is powered by one of the motors without using a power of the other motor to be used to start the engine; and starts the engine upon satisfaction of a condition for propelling the vehicle by the power of the other motor.
