When a first automatic stopping condition is established while a vehicle (A,B) is stationary or a second automatic stopping condition is established during travel, an internal combustion engine () of the vehicle is automatically stopped. The first automatic stopping condition is established when a battery voltage or a battery state of charge of a battery () equals or exceeds a first threshold, and the second automatic stopping condition is established when the battery voltage or the battery state of charge of the battery () equals or exceeds a second threshold. By setting the second threshold to be greater than the first threshold, opportunities for automatically stopping the internal combustion engine () are secured while satisfying a power requirement of an electrical load () during restarting of the internal combustion engine ().

Automatic stopping device and automatic stopping method for internal combustion engine

An automatic engine-stop control device for a vehicle has a coast stop controlling section that stops an engine during a running of the vehicle when a predetermined condition is satisfied, a deceleration detecting section that detects a deceleration level of the vehicle, and an engine-stop time limiting section that limits a time length for which the coast stop controlling section keeps the engine in a stopped state if the deceleration level is smaller than or equal to a predetermined value.

Automatic engine-stop control device for vehicle

An internal combustion engine () of a vehicle (A,B) is automatically stopped when a first automatic stopping condition is established while the vehicle is stationary or a second automatic stopping condition is established while the vehicle travels. The first automatic stopping condition requires a road gradient equal to or smaller than a first gradient threshold, and the second automatic stopping condition requires the road gradient equal to or smaller than a second gradient threshold. By setting the second gradient threshold at a smaller value than the first gradient threshold, a feeling of unease experienced by a driver when the engine is stopped on a slope is reduced.
