Abstract
Disclosed herein is a vehicle having improved engine startability using hardware wake-up period control by performing a vehicle state detection mode to which a battery voltage, an engine oil temperature, and an engine coolant temperature are applied by a controller in a key-off state of an engine, a wake-up fuel pressure control mode for determining whether a soaking time reaches a wake-up set time by the count of a key-off timer for 80 minutes, a pump operation control mode for operating a low-pressure fuel pump for approximately 1 second by the current supplied in response to a key-off output signal over the period of 80 minutes, and a wake-up repetition control mode for repeating a number of times the low-pressure fuel pump is operated to maximum 6 times.
