動停止始動装置。Used in vehicles that are supplied with engine intake negative pressure and have a brake booster capable of supplying negative pressure with a vacuum pump, there is a sensor group that outputs signals indicating the status of the engine and various parts of the vehicle, and stop signal generating means for outputting an engine stop signal when it is determined based on the signal that an engine automatic stop condition is satisfied;
restart signal generating means for outputting an engine restart signal when it is determined that an engine restart condition is satisfied based on the signals from the sensor group; and an engine stop for stopping the engine in response to the engine stop signal. means and
The automatic engine stop/start device includes an engine restart means for restarting the engine in response to the engine restart signal, and a parking brake operation detection means for detecting that the parking brake is activated, and the brake booster. a negative pressure detection means for detecting negative pressure within the booster; and a parking brake operation detection means for detecting that the parking brake is operating, and detecting that the negative pressure within the booster is below a predetermined value. An automatic engine stop/start device comprising pump drive signal generation means for outputting a vacuum pump drive signal for driving the vacuum pump when detected by the detection means.
