Abstract
Official abstract text for this publication.
An automatic engine control apparatus installed in a vehicle causes an engine of the vehicle to stop automatically when a predetermined stop condition is satisfied, and after the automatic stop of the engine, causes the engine to restart automatically when a predetermined restarting condition is satisfied. The apparatus includes an electronic control unit configured to inhibit or permit, while the vehicle is stopped, a second automatic stop of the engine in response to the predetermined stop condition being satisfied, depending on whether the predetermined restarting condition satisfied most recently to have caused the engine to restart automatically was a first restarting condition or a second restarting condition different from the first restarting condition. The first restarting condition represents an intention of a driver of the vehicle to start moving the vehicle.
First claim
Opening claim text (preview).
1 . An automatic engine control apparatus installed in a vehicle, configured to have an engine of the vehicle stop automatically when a predetermined stop condition is satisfied, and after automatically stopping the engine, to have the engine restart automatically when a predetermined restarting condition is satisfied, the apparatus comprising: an electronic control unit configured to inhibit, while the vehicle is stopped, a second automatic stop of the engine in response to the predetermined stop condition being satisfied when the predetermined restarting condition satisfied most recently to have caused the engine to restart automatically was a first restarting condition, or to permit the second automatic stop of the engine in response to the predetermined stop condition being satisfied when the predetermined restarting condition satisfied most recently to have caused the engine to restart automatically was a second restarting condition different from the first restarting condition, wherein the first restarting condition represents an intention of a driver of the vehicle to start moving the vehicle. 2 . The automatic engine control apparatus as claimed in claim 1 , wherein the first restarting condition that represents the intention of the driver to start moving the vehicle is a steering operation or an acceleration operation by the driver. 3 . The automatic engine control apparatus as claimed in claim 1 , wherein while the vehicle is traveling, the electronic control unit inhibits the automatic stop of the engine in response to the predetermined stop condition being satisfied when the predetermined restarting condition that was satisfied most recently to have caused the engine to restart automatically was a third restarting condition. 4 . The automatic engine control apparatus as claimed in claim 3 , wherein the electronic control unit permits the automatic stop of the engine in response to the predetermined stop condition being satisfied when the third restarting condition was satisfied while the vehicle was stopped. 5 . The automatic engine control apparatus as claimed in claim 3 , wherein the third restarting condition is a condition different from the first restarting condition. 6 . The automatic engine control apparatus as claimed in claim 2 , wherein the second restarting condition is one or more of an air conditioning requirement, a battery charging requirement and a shift operation requirement. 7 . The automatic engine control apparatus as claimed in claim 3 , wherein the third restarting condition is one or more of a braking operation requirement, a road surface slope requirement, a brake negative pressure requirement and a brake master cylinder requirement.
