を含むようになっており、
微調節アセンブリは、
a.粗調節アセンブリからの入力と、
b.計算される制御シーケンスの最小化および長さのために、目的関数がどれ位の今後のサンプルを考慮するか決定する予知ホライゾンと、

本発明の装置は、適応(モデル)認知制御(APACC)を使用して人工予知(AP)を提供すると見なすことができる。APACCは、モデル予測制御(MPC)を改良する。非常に複雑なアルゴリズムを使用して、APACCは、非常に高いレベルの推論思考およびリアル・タイム通信を可能にする。利用可能なセンサの融合により、APACCは、車両の周囲を「認知」し、外部環境の真正な「知覚」を与える能力を提供する。これは、人間が蓄えた記憶および感覚入力の組み合わせを使用して、イベントが発生するに連れてこれらを解釈し、ありそうなシナリオを予測する(認知する)方法を模擬するのにいくらか助けになることによって、これまでに可能であったことを遙かに凌駕する。

を含む。
b.APACCは、瞬時的に、実際の出力と、認知された(可能なおよび可能性が高い)出力との間の誤差を補償する。出力は、車の動特性に安定性を与えるスロットル制御および操縦を含む。
d.センサ・アクチュエータに制御出力を供給するコントローラに誤差を供給し、車両の方向または速度を変えるために必要な機械的作用を与える。
