とを特徴とするエンジン自動停止始動処理。A sensor group that is used in a vehicle that is supplied with engine intake negative pressure and has a brake booster that can supply negative pressure with a vacuum pump, and outputs a signal indicating the state of the engine and each part of the vehicle; stop signal generating means for outputting an engine stop signal when it is determined that an engine automatic stop condition is satisfied based on the signals from the sensor group; restart signal generating means for outputting an engine restart signal when it is determined that the engine restart signal is present; engine stopping means for stopping the engine in response to the engine stop signal; and restarting the engine in response to the engine restart signal. An automatic engine stop/start device comprising: negative pressure detection means for detecting negative pressure in the brake booster; and negative pressure detection means for detecting that the negative pressure in the booster is below a predetermined value. measuring means for measuring a predetermined time after the booster; outputting a vacuum pump drive signal for driving the vacuum pump when the negative pressure detecting means detects that the negative pressure in the booster is below a predetermined value; An automatic engine stop/start process comprising pump drive signal generating means configured to stop outputting the vacuum pump drive signal when a predetermined time is measured by the means.
