  • Patent number: 9624992
    Abstract: A control device that controls a vehicle drive device in which a rotary electric machine is provided in a power transfer path that connects between an internal combustion engine and wheels. Engagement of a second engagement device is started when a change in shift range from a stop range to a running range is detected when output torque of the rotary electric machine is zero with the internal combustion engine rotating and with both the first engagement device and the second engagement device disengaged. Engagement of a first engagement device is started after engagement of the second engagement device is started, and the output torque of the rotary electric machine is increased from zero at the same time as engagement of the first engagement device is started or before engagement of the first engagement device is started.

  • Patent number: 9428176
    Abstract: A control device that controls a vehicle drive device in which a first rotating electrical machine and a speed change mechanism are provided on a power transmission path connecting an internal combustion engine and wheels. The control device includes a first pump that is driven by the first rotating electrical machine and a second pump that is driven by a second rotating electrical machine provided independently of the power transmission path. The control device is configured with an auxiliary drive control section that, when a main power supply of a vehicle is turned on, executes auxiliary drive control of driving the first pump for a set drive time by the first rotating electrical machine before driving the second pump by the second rotating electrical machine, and starting the second pump after elapse of the set drive time.

  • Publication number: 20150203099
    Abstract: Provided is a control device such that, when a first engaging device (CL1) is controlled in a sliding engagement state, a decrease in torque transmitted to a wheel (W) in the event of an increase of the temperature of an engaging member of the first engaging device (CL1) is suppressed, while a temperature increase of the engaging member is suppressed. The control device is provided with: a first engagement slide control unit that controls a second engaging device (CL2) to a direct-connection engagement state during a rotating operation of an internal combustion engine (E), and that controls the first engaging device (CL1) to the sliding engagement state; and a temperature increase suppressing control unit that causes an output torque of a rotating electrical machine (MG) to be increased while causing a transmission torque of the first engaging device (CL1) to be decreased when the temperature of the first engaging device (CL1) is increased during first engagement slide control.

  • Publication number: 20130008759
    Abstract: There is provided a first and second bearing supporting a clutch case at first and second axial sides in a radial direction, a rotor of a rotary electrical machine is supported by the clutch case, a gap between an outer peripheral face of a pump drive shaft 10 and an inner peripheral face of a drive shaft insertion hole 90c is a distribution passage L of oil flowing from a pump chamber 18a to the first bearing 51, and a distribution passage diameter difference, which is a difference between a diameter ?a of the outer peripheral face of the pump drive shaft 10 and a diameter ?c of the inner peripheral face of the drive shaft insertion hole 90c in the distribution passage L, is set so that the distribution passage L functions as a narrowed portion which limits a flow rate of oil.

  • Publication number: 20120242198
    Abstract: A vehicle drive device including a rotating electrical machine having a rotor and a stator, as a driving source force of wheels; a rotation sensor that detects a rotational position of the rotor with respect to the stator; a rotor support member that supports the rotor at a position radially inside the stator; an oil pump having a pump rotor disposed on a same axis as the rotating electrical machine and drivingly coupled to the rotor support member, and a pump case accommodating the pump rotor; and a support bearing that is placed between the pump case and the rotor support member in a radial direction, and that rotatably supports the rotor support member with respect to the pump case. The rotation sensor and the support bearing are positioned so as to overlap each other as viewed in the radial direction.

  • Publication number: 20120217825
    Abstract: A vehicle drive system includes a rotor support that is more radially inward than the stator and supports the rotor; a supply that supplies oil to the rotor support bearing, the rotor support bearing includes a discharge that discharges oil supplied from the supply, the rotor support includes an opposing surface that opposes the discharge-side surface, and an opposing extension surface that extends radially from the opposing surface. The stator includes a coil end that protrudes from the stator core toward the first axial direction. A radial outer end of the opposing extension surface is more radially inward than, and overlaps with, the coil end, with a radial space between the radial outer end and the coil end. The discharge-side surface is disposed more toward the second axial direction than the radial outer end of the opposing extension surface.
