Title:
ENGINE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/084446
Kind Code:
A1
Abstract:
The present invention provides an engine control device that controls an engine of a vehicle, having: an instantaneous-interruption determining circuit; a holding circuit; and a control unit. The instantaneous-interruption determining circuit includes a first capacitor and a first resistor that discharges and charges the first capacitor at a first time constant. The holding circuit includes a second capacitor and a second resistor that discharges and charges the second capacitor at a second time constant equal to or larger than the first time constant. The control unit controls the engine on the basis of the voltage states of the first capacitor and the second capacitor. Furthermore, the control unit starts to charge the first capacitor after starting to charge the second capacitor. Even if the control unit of the engine control device is reset due to a temporary reduction in battery voltage, information indicating the engine control state immediately before the reset can be held.
