Title:
POWER TRANSMISSION DEVICE FOR HYBRID VEHICLE
Document Type and Number:
Japanese Patent JP2016203833
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To allow balance between speed-change control of a mechanical stage transmission portion and rotation-speed control of an electric non-stage transmission portion to be secured regardless of torque restriction for a motor generator by charge/discharge allowance amounts of a battery.SOLUTION: Oil pressure of a clutch C and a brake B at the time of speed change of a mechanical stage transmission portion 14 is corrected according to charge/discharge allowance amounts of a battery 24, and consumption power (inertial power at the speed change, clutch loss, driving power and the like) in the mechanical stage transmission portion 14 is increased and decreased, so that income/outgo balance between input power and the consumption power can be secured regardless of torque restriction for the input power (engine power and battery power) from an electrical non-stage transmission portion 12 accompanying torque restriction for motor generators MG1 and MG2. This allows rotation speed control for the electric non-stage transmission portion 12 relative to speed change of the mechanical stage transmission portion 14 to be performed with good balance in a condition nearly equal to an original setting regardless of restriction on the charge/discharge of the battery 24.SELECTED DRAWING: Figure 1
