Abstract

A running control device of a vehicle includes an engine with a plurality of cylinders, a clutch connecting/disconnecting a power transmission path between the engine and wheels, a fuel pump transferring fuel toward an injector, and a fuel pressure control device controlling a fuel pressure in a transfer path of the fuel. The running control device of a vehicle performs a neutral inertia running mode performed with the power transmission path between the engine and the wheels disconnected, and a cylinder resting inertia running mode performed by resting at least a part of the cylinders of the engine with the power transmission path between the engine and the wheels connected, the fuel pressure during the neutral inertia running mode being made higher than the fuel pressure during the cylinder resting inertia running mode.
