AUTOMATIC ENGINE STOPPING/RESTARTING DEVICE, AND AUTOMATIC ENGINE STOPPING/RESTARTING METHOD

摘要

In order to provide an engine automatic stop and restart apparatus capable of realizing excellent startability, and preventing an excessive load from being imposed on a starter (30) and a power transmission system, a starter drive inhibition determination section (12) inhibits, in a case where an engine restart condition is satisfied, when a backward rotation of an engine (20) is detected based on a crank angle of a crankshaft of the engine (20) detected by a crank angle sensor (1) for detecting the crank angle, a drive of the starter (30) configured to crank the crankshaft so as to restart the engine (20), and releases, when a stop of the engine (20) is detected, the drive inhibition of the starter (30).

主权项

1. An engine automatic stop and restart apparatus for stopping fuel injection into an engine to automatically stop the engine when an engine automatic stop condition is satisfied, and then restarting the engine when an engine restart condition is satisfied,
the engine automatic stop and restart apparatus comprising: a crank angle sensor for detecting a crank angle of a crankshaft of the engine; a starter for cranking the crankshaft, thereby restarting the engine; and a starter drive inhibition determination section for inhibiting, in a case where the engine restart condition is satisfied, a drive of the starter when a backward rotation of the engine is detected based on the crank angle detected by the crank angle sensor, and releasing the drive inhibition of the starter when the stop of the engine is detected.
