Title:
内燃機関制御装置
Document Type and Number:
Japanese Patent JP6455185
Kind Code:
B2
Abstract:
This internal-combustion engine control device comprises: a pump cell (246) for discharging oxygen from a measuring chamber (242) into which discharged gas from an internal-combustion engine (20) is introduced; a sensor cell (248) for detecting a residual oxygen concentration in the discharged gas from which the oxygen has been discharged, and for detecting a specific gas concentration in the discharged gas; and a monitor cell (249) for detecting the residual oxygen concentration in the discharged gas from which the oxygen has been discharged. The internal-combustion engine control device is provided with a pump cell detecting unit (402), a sensor cell detecting unit (403), a monitor cell detecting unit (404), an abnormality determining unit (406) and a control unit (10). The control unit performs first control of the internal-combustion engine in response to an abnormality occurring in an electrical system connected to the pump cell, performs second control of the internal-combustion engine in response to an abnormality occurring in an electrical system connected to the sensor cell, and performs third control of the internal-combustion engine in response to an abnormality occurring in an electrical system connected to the monitor cell.
