ENGINE SHUTDOWN CONTROL DEVICE AND ENGINE SHUTDOWN CONTROL METHOD

WIPO Patent Application WO/2019/059021

A1

The present invention prevents idling of an engine from being stopped when there is a disconnected wire in a battery. This engine shutdown control device is for an engine-driven vehicle having mounted therein an in-vehicle battery, an alternator that is connected to the in-vehicle battery and that is for generating electricity while the engine is running, and a starter for starting the engine by using the electric power supplied from the in-vehicle battery. The engine shutdown control device is provided with: a shutdown control unit which shuts down the engine upon receipt of shutdown permission information in the case when the speed of the vehicle has dropped to a level lower than a prescribed value; a detection unit which detects the current flowing to the in-vehicle battery and the voltage applied to the in-vehicle battery; and a shutdown permission/rejection determination unit which, on the basis of the current detection value and the voltage detection value detected by the detection unit, determines whether or not there is a disconnected wire in the in-vehicle battery, and transmits the shutdown permission information to the shutdown control unit in the case when it is determined that there are no disconnected wires.
