Title:
VEHICLE CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2023104799
Kind Code:
A
Abstract:
To provide a vehicle control device that is provided with driving force sources including an electric motor, a stepped transmission including a plurality of engagement devices, a mechanical oil pump that is driven by the electric motor, and an electric oil pump, which can reduce shock that is caused during creep-cut return control.SOLUTION: In returning creep-cut control to creep control, oil pressure can be secured by driving an electric oil pump 60 prior to increase in MG rotation speed Nm of an electric motor MG just after returning the creep-cut control to the creep control. Thereafter, the oil pressure can be secured by driving a mechanical oil pump 58 accompanying the increase in the MG rotation speed Nm of the electric motor MG. This enables CB oil pressure PRcb of an engagement device CB for speed change to follow prescribed pressure, which can suppress occurrence of shock due to rapid increase of the CB oil pressure PRcb of the engagement device CB for speed change.SELECTED DRAWING: Figure 1
