Claims (1)

[Scope of utility model registration request] Starting operation detection means for detecting a predetermined starting operation in an automatic engine stop/start device that automatically stops the engine by detecting a deceleration or stop state of the vehicle and automatically starts the engine by detecting an acceleration or starting operation of the vehicle. a rotation speed detection means for detecting the rotation speed of the engine; a generated voltage detection means for detecting the output voltage of the alternator; a stop determination means for determining whether the engine has stopped based on the rotation speed and the output voltage of the alternator; a starting signal generating means that outputs a starting signal based on a predetermined starting operation when it is determined that the engine has stopped, and stops outputting the starting signal when starting of the engine is completed; 1. An automatic stop/start device for an engine, comprising: a start determining means for determining completion of engine start based on the output voltage of the engine; and an engine drive means for driving the engine based on a start signal.
