摘要： PROBLEM TO BE SOLVED: To provide a travel control device for a vehicle capable of suppressing deterioration in fuel consumption while suppressing deterioration in drivability in an inertial travel.SOLUTION: When an engine oil temperature Toil is low, a neutral inertial travel is made to have a deceleration. When the engine oil temperature Toil is high, on the other hand, a cylinder-stop inertial travel is made to have small deceleration. Consequently, variation in deceleration caused by variation in engine oil temperature Toil becomes small and a stable travel feeling can be thereby obtained during the inertial travel. Further, the neutral inertial travel is not always made so as to eliminate variation in deceleration, so deterioration in fuel consumption and deterioration in drivability resulting from that the neutral inertial travel is always made are prevented. Consequently, the deterioration in fuel consumption can be suppressed while the deterioration in drivability during the inertial travel is suppressed.
摘要翻译：要解决的问题：提供一种能够抑制惯性行驶中的驾驶性能劣化的能够抑制燃料消耗劣化的车辆行驶控制装置。解决方案：当发动机机油温度Toil低时，使中性惯性行驶具有减速。另一方面，当发动机机油温度Toil较高时，气缸停止惯性行驶减速度小。因此，由于发动机机油温度Toil变化引起的减速度变小，因此在惯性行驶中可以获得稳定的行驶感。此外，中性惯性行驶并不总是为了消除减速度的变化，因此防止了总是进行中立惯性行驶所导致的燃料消耗的劣化和驾驶性能的恶化。因此，能够抑制惯性行驶中的驾驶性能的劣化，能够抑制燃料消耗的劣化。

摘要： PROBLEM TO BE SOLVED: To hardly give discomfort to a driver even if neutral inertia travel is impossible when artificial conditions are satisfied.SOLUTION: Even if the neutral inertia travel is impossible, cylinder deactivation inertia travel is possible depending on a vehicle condition. When the vehicle conditions are satisfied, the cylinder deactivation inertia travel is performed during travel such as the neutral inertia travel to improve fuel consumption and approximate a travel condition involving a sense of gliding expected by a driver, as compared with the case of uniformly prohibiting inertia travel, thus giving less discomfort to the driver. As a result, even if the neutral inertia travel is impossible when the artificial conditions are satisfied, the discomfort can be hardly given to the driver.

摘要： PROBLEM TO BE SOLVED: To further improve fuel economy of a vehicle while securing the functionality of amplifying braking force when a brake is operated in the vehicle enabled to perform inertia travel in which the engine brake force is lower than in an engine-brake travel.SOLUTION: In consideration of functionality of amplifying braking force when a brake is operated, a difference is made in upper limits (α, β) of a brake operation force Brk in starting execution of a free-run inertia travel and of a neutral inertia travel on the basis of determination as to whether it is possible to fill a brake booster 42 with negative pressure, and therefore it is possible to widen a range of the brake operation force Brk in starting execution of an inertia travel while securing braking force when the brake is operated, improving fuel economy.

Meanwhile, when vehicular speed-maintaining cruise control in which the followability to a preceding vehicle is not necessary is engaged, a vehicle fuel economy is improved because the free-run inertia travel in which the engine 12 stops is selected. This makes it possible to balance between improvement in the vehicular fuel economy and followability to a preceding vehicle when cruise control is engaged.
