Abstract
A running control device of a vehicle includes an engine and a brake booster amplifying a brake force by forming a negative pressure in a negative pressure tank by rotation of the engine. The running control device is configured to execute an engine brake running mode performed with the engine coupled to wheels such that an engine brake is applied by driven rotation of the engine and an inertia running mode performed with an engine brake force made lower than that of the engine brake running mode. The running control device executes a first inertia running mode performed with the rotation of the engine stopped and a second inertia running mode performed with the engine kept rotating as the inertia running mode in accordance with predefined respective execution conditions. The running control device comprises a prediction portion configured to predict a necessity of the negative pressure.
