Vehicle control system

A vehicle control system is provided. The vehicle control system is applied to a vehicle comprising an engine having a plurality of cylinders, a power transmission route between the engine and drive wheels and a clutch device adapted to selectively connect and disconnect the power transmission route, and that is configured to disconnect the power transmission route during running to allow the vehicle to coast. The vehicle control system is comprised of: a means that detects a vehicle speed; a means detecting an operation of an accelerator by a driver; a means detecting a speed of the engine; an execution means executing 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 while controlling the engine in a manner such that the engine speed is reduced to be lower than an idling speed that is lower than the engine speed of a case in which the coasting control is not carried out; and a deactivation means connecting the power transmission route by bringing the clutch device into engagement while stopping fuel supply to the engine and deactivating intake valves and exhaust valves of the cylinders, when the vehicle speed exceeds a reference speed or an increasing amount of the vehicle speed exceeds a reference value.
