Claim:
1. A vehicle control system, that is applied to a vehicle having a clutch device adapted to selectively connect and disconnect a power transmission route between a prime mover and drive wheels, and that is configured to disconnect the power transmission route during running to allow the vehicle to coast, comprising a controller that is configured to: detect a vehicle speed; detect an operation of an accelerator by a driver; detect a braking operation of the driver; execute a coasting control when an operating amount of the accelerator is reduced to be smaller than a predetermined value during running, by bringing the clutch device into disengagement to disconnect the power transmission route so as to allow the vehicle to coast; determine whether or not a deceleration demand of the driver is larger than a predetermined value during execution of the coasting control based on the vehicle speed and the braking operation; determine a fact that the deceleration demand is strong if the deceleration demand is larger than the predetermined value, and terminate the coasting control by bringing the clutch device into engagement to connect the power transmission route; determine a probability that the deceleration demand is judged to be strong based on the vehicle speed and the braking operation; and reduce a speed difference between a rotary member of the clutch device of the prime mover side and a rotary member of the clutch device of the drive wheel side prior to terminating the coasting control, by controlling a speed of the prime mover.
