Abstract
In consideration of an amplification effect of a braking force at the time of brake operation, upper-limits (α, β) 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.
