A vehicle control system is provided. The vehicle control system is applied to a vehicle having a clutch device to selectively connect and disconnect a power transmission route between a prime mover and drive wheels, and configured to disconnect the power transmission route during running to allow the vehicle to coast. The vehicle control system is comprised of: a vehicle speed detection means; an execution means that executes a coasting control when an operating amount of an 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; an updating means that updates a lowest speed of the vehicle during execution of the coasting control; and a termination means that terminates the coasting control by bringing the clutch device into engagement to connect the power transmission route, when a difference between a current vehicle speed and the latest lowest vehicle speed exceeds a predetermined value.
