  "textContent": "A control arithmetic unit uses a control storage area and computes a target control amount for combustion of an internal combustion engine according to a user required torque. A monitoring arithmetic unit uses a monitoring storage area and performs computation and monitoring of presence or absence of a torque anomaly state in which an estimated torque is deviated from an engine required torque by a predetermined amount or more. The monitoring arithmetic unit includes an engine required torque computation unit that computes the engine required torque and an estimated torque computation unit that computes the estimated torque. The engine required torque computation unit computes a reduction in an actual torque, which is caused in conjunction with a retard in ignition timing of the internal combustion engine, as a reserve torque and computes the engine required torque based on the calculated reserve torque and the user required torque.",
