The purpose of the present invention is to further improve fuel economy while ensuring amplification of braking force upon brake operation in a vehicle capable of coasting in a state in which there is less engine-braking force than when traveling with engine braking. Free-run coasting, which produces excellent fuel efficiency by traveling with the engine (12) stopped, is maintained until a brake-pedal force (Brk) reaches a first threshold (alpha), and coasting in neutral, which produces appropriate amplification of the brake-pedal force (Brk) via a brake booster (42) by traveling with the engine (12) still running, is maintained until a second threshold (beta) that is higher than the first threshold (alpha) is reached. Accordingly, the overall fuel economy is further improved while ensuring that brake operation produces a sufficient vehicle-braking force, relative to the use of only free-run coasting or only coasting in neutral,.
