Title:
車両の制御装置
Document Type and Number:
Japanese Patent JP7226178
Kind Code:
B2
Abstract:
To provide a control device for a vehicle, which prevents oil mist in a casing from jetting out of the casing from a breather due to a rise of air temperature in the casing.SOLUTION: In a case where it is determined that a quantity of oil mist Qm generated in a casing 14 on the basis of an MG temperature Tm and a rotational speed N is determined to be larger than a predetermined quantity Qth and, in addition, it is determined that a climb gradient ΔTa of an air temperature in the casing 14 is determined to be larger than a predetermined climb gradient ΔTth, at least one of torque reduction control for reducing MG torque Tg and rotational speed decrease control for decreasing a planetary difference rotational speed ΔNp is executed. Consequently, misting of oil in the casing 14 based on the MG temperature Tm and the rotational speed N is hindered, making it possible to prevent oil mist in the casing 14 from jetting out of the casing 14 via a breather 50.SELECTED DRAWING: Figure 4
