Claims

[Scope of Claim for Utility Model Registration] (a) Operating state detection means for detecting the operating state of the engine; (b) Stop signal generating means for outputting a stop signal when the engine is in an operating state that satisfies a predetermined stop condition. , (C) engine stopping means that automatically stops the engine based on a stop signal; (d) starting operation detecting means that detects vehicle acceleration or starting operation; (e) starting based on the output of the driving state detecting means. (f) a starter motor name that drives the engine when a motor start signal is input; (g) a starter motor that stores rotational energy of the engine and uses the rotational energy when an inertia start signal is input; (h) comparison means for comparing the rotational energy of the inertial drive means with a predetermined value; <i) when a starting operation is performed while the engine is in an automatic stop state, If the rotational energy is above a predetermined value, the inertia start signal is output; if it is less than the predetermined value, the motor start signal is output; and if the rotational energy is about to drop below the predetermined value when in the automatic stop state. An automatic engine stop/start device comprising a start signal generating means that outputs an inertia start signal and stops outputting the inertia start signal and the motor start signal when it is determined that the start is complete.
