摘要： A traveling information providing device is provided in which a surrounding information corrector acquires surrounding information on the condition surrounding a vehicle equipped with the device. An object extractor extracts a safety confirmation object the safety of which must be confirmed by a driver from the surrounding information acquired by the surrounding information collector. A line-of-sight detector detects a line-of-sight direction of the driver. A visibility calculator receives the extracted safety confirmation object and the line-of-sight direction of the driver and calculates visibility in consideration of the driver's peripheral vision with respect to the safety confirmation object according to the distance or the angle from the driver's line-of-sight direction to the object. An information presenter presents safety confirmation to the driver depending on the calculated visibility.

摘要： Provided is a stereo distance measurement apparatus wherein a camera image itself is adjusted to correct the blur, thereby preventing the distance measurement time from being long, while improving the precision of disparity detection. In the apparatus (100), a blur adjusting unit (102) uses a filter to tailor the blur of one of two images used by a disparity measuring unit (103), to the blur of the other which is weaker. A camera image itself is adjusted, whereby the blur can be corrected. Moreover, tailoring the blur of the one image to the blur of the other image which is weaker allows an application of the filter, which is a simple processing, to cause the blurs of the images used in the disparity detection, to coincide with each other. Therefore, the precision of disparity detection can be improved, while the distance measurement can be performed at a high speed.

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.

摘要： To reduce the amounts of HC, NOx and other emissions from a direct injection engine when a catalyst is still in its unheated state, and to promote catalyst quick light-off operation by increasing the temperature of exhaust gases, a control device comprises a temperature state identifier (31) for judging the temperature state of a catalyst (22) and a fuel injection controller (33) for controlling fuel injection from an injector (11). The fuel injection controller (33) controls the injector (11) based on judgment results of the temperature state identifier (31) in such a way that the injector (11) makes at least two-step split injection during a period from an intake stroke to an ignition point including a later injection cycle performed in a middle portion of a compression stroke or later and an earlier injection cycle performed prior to the later injection cycle at least in a low-load range of the engine when the catalyst (22) is in its unheated state, in which its temperature is lower than its activation temperature, and either of the later injection cycle and earlier injection cycle injects fuel which contributes to main combustion during a main combustion period in which approximately 10% to 90% by mass of the injected fuel is burnt in a combustion process occurring in the combustion chamber.
