摘要： A driving support device wherein an own vehicle and a peripheral vehicle are symbolized, and relative dispositions are displayed in real time in a display unit visible to the driver, is obtained to facilitate a lane change by a driver. The driving support device includes a vehicle detecting unit, which detects peripheral vehicles positioned in a periphery of a vehicle, and an image generating unit, which generates an image representing positions of the vehicle and the peripheral vehicles from vehicle information obtained by the vehicle detecting unit. The image generating unit generates a driving support image including vehicle information representing relative dispositions of the vehicle and the peripheral vehicles using symbols indicating the vehicle and the peripheral vehicles. The image generating unit includes an image stacking unit, which generates original data of the driving support image, and an image control unit, which cuts a necessary portion from the original data.

摘要： Provided are a lane separation line detection correcting device/method and an automatic driving system for stabilizing the behavior of a vehicle by correcting overestimated curvature information resulting from an erroneous detection of a curvature of a lane separation line. A travel speed detecting circuit detects, for example, a target travel speed as vehicle sensor information. A maximum curvature estimating circuit estimates, based on the target travel speed, a maximum curvature of a road along which an own vehicle is traveling. A curvature correcting circuit corrects a curvature of a lane separation line input thereto based on the maximum curvature. A control unit controls steering of the own vehicle based on the lane separation line having a corrected curvature. As a result, vehicle steering can be automatically controlled so as to prevent the own vehicle while traveling from departing from a driving lane.

摘要： To provide an other vehicle behavior prediction apparatus, an other vehicle behavior prediction method, and an automatic driving system which can determine the presence absence of the lane change of the other vehicle with good accuracy, regardless of the change of road shape. An other vehicle behavior prediction apparatus, including: a periphery detector that detects other vehicle which exists around an own vehicle; a road shape detector that detects a road shape where the other vehicle is located; and a lane change predictor that predicts presence or absence of a lane change of the other vehicle based on a detection result of the other vehicle, and changes a determination value which is used when predicting the presence or absence of the lane change of the other vehicle, based on the road shape where the other vehicle is located.

摘要： A synthesized image seen looking down from above the vehicle is compiled by connecting the multiple of overhead images, whereby an existence of a three-dimensional object in the vehicle periphery is determined, a correction value is calculated so as to reduce a difference in luminance and coloring in a luminance and coloring correction reference region in which neighboring overhead images overlap, luminance and coloring correction is carried out using the correction value when an amount of change in the luminance and coloring information formed of the correction is less than a predetermined value, and the images wherein luminance and coloring has been corrected are synthesized by connecting into one image, whereby a beautiful display image with a continuous, smooth joint can be obtained.

摘要： A conveyance system includes: a travel plan generating unit to generate a travel plan of the conveyance vehicle, the travel plan being used to execute conveyance of the trailer from the parking lot to a platform by the conveyance vehicle or conveyance of the trailer from the platform to the parking lot; and an extraneous vehicle determining unit to determine whether or not the extraneous vehicle is present in the site. When the extraneous vehicle determining unit determines that the extraneous vehicle is present in the site, the travel plan generating unit generates the travel plan in which the conveyance vehicle does not obstruct traveling of the extraneous vehicle. In this case, traveling of the extraneous vehicle such as a truck is not obstructed by the conveyance vehicle, so that operation efficiency of the delivery center can be improved.
