    摘要: 【課題】自車両の予測走行進路と障害物との距離を考慮して、自車両に衝突する可能性が高い障害物に対して適切にドライバーの注意を喚起させることができる運転支援装置を提供すること。 【解決手段】注意喚起ECU10は、カメラセンサ11及びレーダーセンサ12から物標情報及び車両状態センサ13により取得された情報に基づいて予測される走行予測進路に基づいて、障害物を抽出し、障害物の注意喚起必要度合の一つとして余裕時間TTCを算出する。注意喚起ECUは、障害物と走行予測進路との距離を算出し、当該距離が小さいほど、余裕時間TTCが小さくなるように補正し、補正後の余裕時間TTCが最小の障害物を処理対象障害物として選択し、当該処理対象障害物の余裕時間TTCが閾値T1th以下であれば、当該処理対象障害物の方向にドライバーの視線を誘導する画面を表示する。 【選択図】図4

    摘要: PROBLEM TO BE SOLVED: To provide a target detection apparatus for identifying a lower-order target, according to a simple method, regardless of a road shape.SOLUTION: A pair which is determined to have history connection over a plurality of cycles and are stationary (of which the relative speed is within e.g., ±5 km/h of a present vehicle speed) is selected as a stationary pair and from among non-processed stationary pairs, a pair satisfying a representative condition (existence at a position closest to a present vehicle) is selected as a representative pair (S220). The number of stationary pairs existing in the same identification range and satisfying the same target condition preset for selecting a stationary pair caused by the same object as the representative pair (the number of identical object pairs) is calculated as a depth determination value (S230). In the case where the depth determination value is equal to or less than a lower-order threshold value, it is determined that the representative pair is caused by a lower-order target (S240 and S250). In the case where the depth determination value is more than the lower-order threshold value, it is determined that the representative pair is caused by a non-lower-order target, and a height of a target is estimated by null pattern identification processing (S240 and S260).

    摘要: PROBLEM TO BE SOLVED: To provide a system that allows a moving object requiring monitoring to be more precisely monitored.
    SOLUTION: The monitoring system includes a first device 100 for transmitting a first transmission signal from one end side to the other end side of both ends of a leaking transmission device as a transmission medium, a second device 200 for transmitting a second transmission signal from the other end side to one end side of both ends of the leaking transmission device as a transmission medium, and a detector section 400 for detecting a two-dimensional movement of a moving object to be monitored on the basis of a difference between variations of a first receiving signal when a first reflected radio wave generated such that a first radio wave emitted by the first transmission signal from either one of first and second leaking transmission paths 301, 302 reflects onto the moving object to be monitored is received via the leaking transmission device, and a second receiving signal when a second reflected radio wave generated such that a second radio wave emitted by the second transmission signal from either one of first and second leaking transmission paths reflects onto the moving object to be monitored is received via the leaking transmission device.

    摘要: PROBLEM TO BE SOLVED: To provide a method of quickly determining a position of a user terminal in a satellite communication system using one low-earth orbit satellite, using a characteristic of a communication signal therein. SOLUTION: A system and method is provided for determining the position of the user terminal (for example, a mobile wireless telephone) in the low-earth orbit satellite communication system 100. The system includes the user terminal 106, at least one satellite 104 with a known position and a known velocity, and a gateway 102 (i.e. terrestrial base station) communicated with the user terminal 106 via the satellite 104. The method includes a step 802 of determining a range parameter, and a step 806 of determining a range rate parameter. A range parameter indicates a distance between the satellite and the user terminal. A range rate parameter indicates a relative radial velocity between the satellite and the user terminal. The position of the user terminal on the Earth surface is determined based on the range parameter, the range rate parameter and the known position and the known velocity of the satellite (810).
