To provide an outside environment recognition device for reducing increases in a circuit scale and power consumption in association with an addition of an abnormality detection function.SOLUTION: An outside environment recognition unit 21 of an arithmetic device in a vehicle control system comprises: a recognition processing section 41 of an artificial intelligence accelerator 32 that recognizes an outside environment of a mobile body on the basis of image data obtained by a camera 11 as an imaging section for imaging the outside environment of the mobile body; an object data generating section 45 that generates object data for expressing the outside environment recognized by the recognition processing section on the basis of a recognition result of the recognition processing section; and an abnormality detecting section 44 of a control chip 33 that detects abnormalities of a data processing system including the imaging section, the recognition processing section, and the object data generating section, on the basis of the abnormality of the object data.SELECTED DRAWING: Figure 2
【課題】異常検出機能の追加に伴う回路規模および消費電力の増加を低減する外部環境認識装置を提供する。【解決手段】車両制御システムにおける演算装置の外部環境認識部21において、人工知能アクセラレータ32の認識処理部41は、移動体の外部環境を撮像する撮像部としてのカメラ11により得られた画像データに基づいて移動体の外部環境を認識する。オブジェクトデータ生成部45は、認識処理部の認識結果に基づいて認識処理部により認識された外部環境を表現するオブジェクトデータを生成する。制御チップ33の異常検出部44は、オブジェクトデータの異常に基づいて、撮像部と認識処理部とオブジェクトデータ生成部とを含むデータ処理系統の異常を検出する。【選択図】図2
