Abstract: A running control device of a vehicle executes a normal running mode with an engine coupled to drive wheels, a first inertia running mode with the engine stopped during running and an engine brake force reduced as compared to the normal running mode, and a second inertia running mode with the engine rotating during running and the engine brake force reduced as compared to the normal running mode. A determining portion determines a necessity of a brake negative pressure during the first or second inertia running mode. The necessity of the brake negative pressure is a condition for returning from the first inertia running mode and the second inertia running mode to the normal running mode. An upper limit value of the necessity of the brake negative pressure for returning from the first inertia running mode is smaller than that for returning from the second inertia running mode.

Abstract: In consideration of an amplification effect of a braking force at the time of brake operation, upper-limits (?, ?) of a brake operation force (Brk) with which the execution of free-run coasting and neutral coasting is started may be different, on the basis of whether or not a brake booster can be filled with a negative pressure. Therefore, while the braking force at the time of brake operation is secured, the range of the brake operation force (Brk) with which coasting is executed can be enlarged, and an improvement in fuel economy can be made.

Abstract: A controller is capable of controlling a coupled engine running mode, in which an engine is coupled to wheels and an engine brake is activated by driven rotation of the engine, and a coasting mode, in which an engine brake force is reduced with respect to that in the coupled engine running mode with mode with the engine brake on, and starts the coasting mode on the basis of the steering angle of a steering member. The controller starts the execution of a first coasting mode when the steering angle is equal to or less than a preset upper limit value and starts the execution of a second coasting mode when the steering angle is greater than the upper limit value. In the first coasting mode, the engine rotation is stopped, and in the second coasting mode, the engine remains rotating.
