ENGINE RESTART CONTROL DEVICE, VEHICLE, AND VEHICLE CONTROL METHOD

An engine restart control apparatus mounted on a vehicle having an engine and a brake system includes: a negative pressure detector configured to detect booster negative pressure; an engine restart controller configured to restart the engine after a stop of the engine; and a storage memory configured to store the booster negative pressure detected by the negative pressure detector. The engine restart controller restarts the engine when the booster negative pressure is reduced by a first set value or more from a reference booster negative pressure, which is detected at a predetermined timing after the stop of the engine, among booster negative pressures stored in the storage memory.
