摘要： An engine control system for controlling combustion of an internal combustion engine equipped with an exhaust gas purifying catalyst. The system controls fuel combustion on the basis of control parameters including air/fuel ratio, ignition timing and intake air flow so as to cause a rise in exhaust gas temperature while an exhaust gas purifying catalyst installed in an exhaust line of the engine is insufficiently warmed or inactive. When a fluctuation of engine speed is detected, the system controls the air/fuel ratio to reach a target value close to a stoichiometric value, for example, a value between 13 and 17, and controls a control parameter other than air/fuel ratio so as to bring the fluctuation of engine speed within limits of stable combustion while the exhaust gas purifying catalyst is insufficiently warmed. The air/fuel ratio feedback control may be commenced immediately after an engine start.

摘要： Provided is a calibration device that can calculate the mounting state of a stereo camera without the placing of a physical marker. In this device, an area setting processor (113) preliminarily sets, for an integrated image in which a road surface image region and a setting-prohibited region are integrated, an arrangement pattern having a plurality of area setting frames, and adjusts the arrangement pattern so that the plurality of area setting frames recede from each other. An extraction processor (114) extracts from distance images a plurality of partial images corresponding to the plurality of area setting frames. A mounting-state calculation unit (104) calculates a mounting-state parameter on the basis of a plurality of partial images, such parameter relating to the mounting state of a stereo camera used to pick up stereo images.

A watched target judging unit 12 judges a watched target among the objects, to which a driver pays attention. A visual-line direction detecting unit 13 detects a visual-line direction of a driver. A visual recognition judging unit 14 judges whether a driver visually recognizes the watched target or not, based on the watched target and a fluctuation pattern of a direction of either or both eyes of the driver. A non-safety recognition judging unit 15 judges whether a driver recognizes non-safety or not, based on the result of visual recognition judged by the visual recognition judging unit 14. A presentation unit 16 informs the content of non safety, based on the result of judging non safety judged by the non-safety recognition judging unit 15.
