PROBLEM TO BE SOLVED: To acquire a risk degree required for determining safety, while suppressing an operation amount and a memory consumption amount, during traveling both at high speed and at low speed.SOLUTION: A peripheral environment recognition device 10 mounted on a vehicle 2 recognizes a peripheral environment of the vehicle 2. The peripheral environment recognition device 10 comprises: an own vehicle information acquisition part 101 for acquiring own vehicle information about movement of the vehicle 2; a peripheral environment element acquisition part 102 for acquiring peripheral environment element information with respect to an environment element around the vehicle 2; and a travel risk degree determination part 105 for determining each travel risk degree at a plurality of positions around the vehicle 2 on the basis of the own vehicle information and the peripheral environment element information. Intervals at a plurality of positions in a front and rear direction of the vehicle 2 changes depending on a travel speed of the vehicle 2.SELECTED DRAWING: Figure 1
【課題】高速走行時と低速走行時の両方について、演算量やメモリ消費量を抑えつつ、安全性の判断に必要な危険度を求める。【解決手段】周辺環境認識装置10は、車両2に搭載され、車両2の周辺環境を認識する。周辺環境認識装置10は、車両2の動きに関する自車情報を取得する自車情報取得部101と、車両2の周辺の環境要素に対する周辺環境要素情報を取得する周辺環境要素取得部102と、自車情報および周辺環境要素情報に基づいて、車両2の周辺の複数の位置における走行危険度をそれぞれ決定する走行危険度決定部105と、を備える。車両2の前後方向における複数の位置の間隔は、車両2の走行速度に応じて変化する。【選択図】図1
