ガウス過程回帰を用いたエンジンノックのモデル化とその制御

抄録

Knock limit control is necessary for high efficient operation of automotive engines. In this paper, we propose an identification and control method of the engine knock using a Gaussian process. Feedforward input is designed by the Gaussian process model approximating knock probability, and its model is updated online by a feedback of the knock intensity value. As modeling methods using the Gaussian process, we apply a heteroscedastic Gaussian process and a recursive Gaussian process. The effectiveness of the proposed method is demonstrated by a numerical simulation.
