Abstract
(EN)
The present invention addresses the problem of appropriately controlling cooling water and oil in accordance with a situation. This computing device controls the flow rate of cooling water supplied to a motor, and an oil pump that supplies oil to a coil of the motor from a gearbox attached to the motor. When the temperature of the oil in the gearbox is less than a first threshold value and the temperature of the coil is less than a second threshold value, the computing device restricts the flow rate of the cooling water supplied to the motor and activates the oil pump.

La présente invention aborde le problème de commande appropriée d'eau de refroidissement et d'huile selon une situation. Ce dispositif informatique commande le débit d'eau de refroidissement fournie à un moteur, et une pompe à huile fournit de l'huile à une bobine du moteur à partir d'une boîte de vitesses fixée au moteur. Lorsque la température de l'huile dans la boîte de vitesses est inférieure à une première valeur seuil et la température de la bobine est inférieure à une seconde valeur seuil, le dispositif informatique limite le débit de l'eau de refroidissement fournie au moteur et active la pompe à huile.
