Abstract
In a controlling device, the automatic stop and start-up conditions for an internal combustion engine are set to enable automatic stop/start-up control reflecting an operator's will or intention without movement of the vehicle feeling incongruous or unresponsive. The controlling device provides an automatic stop condition when all of the following conditions are satisfied (1) vehicle speed is less than a set value other than zero, (2) an idle switch is on, and (3) a gear position of the transmission is in neutral. An automatic start-up condition is satisfied when any one of the following conditions is satisfied, (1) the clutch is changed to a disengaged state from a fully or half engaged state, (2) the gear position of the transmission is in non-neutral, (3) the idle switch is off, or (4) a condition of booster negative pressure.
