Claims

[Scope of utility model registration request]

A driving state detecting means for detecting the traveling state of the vehicle, a valve opening detecting means for detecting the valve opening of the throttle valve, a handbrake use state detecting means for detecting the use state of the handbrake, and each of the above-mentioned detecting means. selection means for selecting a unit cut signal generating means, a unit cut signal inhibiting unit, a unit cut signal stopping unit, and a starter drive signal generating unit based on the signal; and a unit cut which is selected and generates a unit cut signal when the vehicle is stopped or decelerated. a signal generating means; a twin cut signal inhibiting means that is selected and prohibits the output of the twin cut signal when the handbrake is in use for a predetermined period of time when the throttle valve is at a predetermined opening degree or more and the vehicle is in a running state; after the twin cut signal is generated; A twin cut signal stopping means that is selected and stops outputting the twin cut signal when the vehicle is started or accelerated; a starter drive signal generating means that is selected and generates a starter drive signal when a predetermined engine restart operation is performed; A twin cut means for cutting off the supply of fuel to the engine based on the twin cut signal, and a restart means for restarting the engine by driving the starter based on the starter drive signal;
An automatic engine stop/start device characterized by comprising:
