SYSTEM FOR RESTARTING INTERNAL COMBUSTION ENGINE WHEN ENGINE RESTART CONDITION IS MET
First Claim
1. A system installed in a vehicle having an internal combustion engine, the system being configured to carry out an automatic stop of the internal combustion engine when at least one engine automatic stop condition is met during the vehicle being decelerated, and restart the automatically stopped internal combustion engine when at least one engine restart condition is met before the vehicle is stopped, the system comprising:
- a vehicle speed obtaining unit that obtains a speed of the vehicle;
a threshold determining unit that determines a threshold based on a predetermined-timing value of the speed of the vehicle, the predetermined-timing value of the speed of the vehicle being obtained by the vehicle speed obtaining unit at a predetermined timing when or after the at least one engine restart condition is met, the threshold being used to determine whether to enable a next automatic stop of the internal combustion engine; and
a stop enabling unit that enables the next automatic stop of the internal combustion engine when the speed of the vehicle obtained after the at least one engine restart condition is met is equal to or higher than the threshold.

Abstract
In a system installed in a vehicle, an automatic stop of an engine is carried out when an engine automatic stop condition is met during the vehicle being decelerated. The automatically stopped engine is restarted when an engine restart condition is met before the vehicle is stopped. A vehicle speed obtaining unit obtains a vehicle speed, and a threshold determining unit determines a threshold based on a predetermined-timing value of the vehicle speed. The predetermined-timing value is obtained at a predetermined timing when or after the engine restart condition is met. The threshold is used to determine whether to enable a next automatic stop of the engine. A stop enabling unit enables the next automatic stop of the engine when the speed of the vehicle obtained after the engine restart condition is met is equal to or higher than the threshold.
