PROBLEM TO BE SOLVED: To provide an own vehicle position recognition device with which recognition accuracy of a position of an own vehicle can be improved.SOLUTION: There is provided an own vehicle position recognition device 1 for recognizing a position of an own vehicle, which comprises a correction unit 15 for correcting the position of the own vehicle estimated by an own vehicle estimation unit 7. The correction unit corrects the position of the own vehicle so that a difference between a position of a feature detected by a sensor and a position of a feature included in feature information. When there are a plurality of feature combinations each consisting of the feature detected by the sensor and the feature represented by the feature information, the correction unit adds weight to the respective feature combinations and corrects the position of the own vehicle using the plurality of feature combinations. The weight added to the feature combinations is larger, as likelihood X is larger.SELECTED DRAWING: Figure 2
【課題】自車位置の認識精度を高めることができる自車位置認識装置を提供すること。【解決手段】自車位置を認識する自車位置認識装置1であって、自車推定ユニット7で推定した自車位置を補正する補正ユニット15を備える。補正ユニットは、センサで検出した地物の位置と、地物情報に含まれる地物の位置との差が減少するように、自車位置を補正する。補正ユニットは、センサで検出した地物と、地物情報で表される地物とから成る地物組み合わせが複数存在する場合、それぞれの地物組み合わせに重みを付け、複数の地物組み合わせを用いて自車位置を補正する。地物組み合わせに付けられる重みは、尤度Xが大きいほど大きい。【選択図】図2
