Abstract: front page image
(EN)A control device applied to a system having an engine adapted so that the expansion ratio of the engine can be changed. The control device has an expansion ratio acquisition section for acquiring the expansion ratio and also has a temperature estimation section for estimating, based on the expansion ratio acquired by the expansion ratio acquisition section, the temperature of exhaust gas discharged from the engine or the temperature of a member placed in a path for the exhaust gas.
(FR)L'invention porte sur un dispositif de commande appliqué à un système ayant un moteur adapté de telle sorte que le taux de détente du moteur peut être amené à changer. Le dispositif de commande comporte une section d'acquisition de taux de détente pour acquérir le taux de détente et comporte également une section d'estimation de température pour estimer, sur la base du taux de détente acquis par la section d'acquisition du taux de détente, la température du gaz d'échappement déchargé par le moteur ou la température d'un élément placé dans un trajet du gaz d'échappement.
