CA 2411105
A method of operating an engine (90) during an over temperature condition (208) to protect the engine (90), an information recording medium incorporating a computer program implementing this protection method, and an electronic control module (100) that performs this protection method are disclosed. A torque value representative of an engine generated torque is recorded in response to an engine temperature exceeding a protection temperature threshold (304). The engine torque is then reduced as a nonlinear function of the temperature signal and the recorded torque value to promote engine cooling.
L'invention concerne un procédé permettant d'activer un moteur (90) pendant un état de surchauffe (208) de manière à protéger ledit moteur (90); un support d'enregistrement d'informations comprenant un programme informatique qui permet de mettre en pratique le procédé de protection; et un module de commande électronique (100) qui exécute le procédé de protection. Une valeur de couple représentant un couple moteur est enregistrée sous l'effet d'une température moteur dépassant un seuil (304) de température de protection. Le couple moteur est ensuite réduit en fonction non linéaire du signal de température et de la valeur de couple enregistrée afin de favoriser le refroidissement du moteur.
