Control device

摘要

A control device for a vehicle. While subject control is performed, a second engagement control unit controls the engagement pressure of the second engagement device to a mid-control set pressure that has been set to be equal to or more than a first engagement pressure and equal to or less than a second engagement pressure. The first engagement pressure is a lower limit engagement pressure capable of maintaining the second engagement device in the directly coupled engaged state, in a state in which requested torque that is torque required to be transmitted to the wheels is transmitted to the wheels. The second engagement pressure is a lower limit engagement pressure capable of maintaining the second engagement device in the directly coupled engaged state, in a state in which maximum output torque of the rotary electric machine is transmitted to the wheels.

主权项

1. A control device that controls a drive device for a vehicle provided with a speed change mechanism in a power transmission path connecting a rotary electric machine and wheels, and also provided with a plurality of engagement devices in the power transmission path, the control device comprising:
a first engagement control unit that controls, as subject control, an engagement pressure of a first engagement device serving as one of the engagement devices to a slip engagement pressure; and a second engagement control unit that controls an engagement pressure of a second engagement device that is an engagement device different from the first engagement device and is one of the engagement devices controlled so as to be in a directly coupled engaged state while the subject control is performed, wherein an internal combustion engine is drivingly coupled to the rotary electric machine via a third engagement device; the control device is structured to perform, while the subject control is performed, internal combustion engine starting control that starts the internal combustion engine in a stop state while causing a state of the third engagement device to transition from a released state to the directly coupled engaged state; and when the subject control and the internal combustion engine starting control is commanded based on a start request of the internal combustion engine in the directly coupled engaged state of the second engagement device, the second engagement control unit performs direct-coupling pressure reducing control that reduces the engagement pressure of the second engagement device to a pressure lower than that before the subject control and the internal combustion engine starting control are performed.
