Claims

[Claim for Utility Model Registration] An automatic engine stop/start device used in a vehicle with an automatic transmission, which includes an idle switch that outputs an idle signal when the throttle valve is almost fully closed, and detects the status of the engine and various parts of the vehicle. a sensor group that outputs an engine stop signal when determining that an engine stop condition is satisfied based on detection signals from the sensor group; restart signal generating means for outputting an engine restart signal when determining that engine restart conditions are satisfied based on detection signals from the sensor group; and engine stop for stopping the engine in response to the engine stop signal. means, engine restart means for restarting the engine in response to the engine restart signal, and selecting a transmission gear of the automatic transmission to third gear or higher when it is determined that the engine stop condition is satisfied; 1. An automatic engine stop/start device comprising: transmission gear selection means for sequentially selecting the transmission gears after starting the engine. −7°
