Idling stop control method, idling stop control device, and idling stop control program

摘要

When a key switch (104) is turned On (Yes at step S1), a decision is made whether idling stop conditions are satisfied or not (step S2), and if the idling stop conditions are satisfied (Yes at step S2), a diesel engine (200) is stopped (step S3). A timer for measuring the time elapsed after stoppage of the diesel engine (200) is then actuated (step S5). Subsequently, a decision is made whether the time T elapsed after stoppage of the diesel engine (200) has reached a predetermined time alpha or not (step S6), and if the time T elapsed after stoppage of the diesel engine (200) has exceeded the predetermined time alpha (Yes at step S6), the diesel engine (200) is restarted (step S8).
