摘要： In a state a vehicle is stopped at an intersection, an infinitely variable transmission is in a neutral position, a motor/generator rotates with a low speed, an oil pump and an auxiliary equipment are in rotating state. At that time, an input clutch is disengaged, and the internal engine is stopped. When the vehicle is started, a continuously variable transmission performs continuous shift control from the neutral position using hydraulic pressure from an oil pump, and the rotation of the motor/generator is transmitted to drive wheels via a ring gear of a planetary gear. After the vehicle has started driving, the input clutch is engaged and the internal engine is started. The vehicle is driven while the motor/generator assists driving or the motor/generator charges batteries based on operation of the internal engine.

摘要： A control system for a vehicular drive unit having an engine, a motor-generator for acting as a motor and a generator; a power transmission including a planetary gear composed of at least three rotary elements and a mechanism for selectively connecting/releasing the rotary elements; a battery for storing electric power generated by the motor-generator and for supplying a driving electric power; a residue detector for detecting the state of charge of the battery; and a controller for controlling the engine, the motor-generator and the connecting/releasing mechanism in accordance with an output signal from the residue detector. The first rotary element of the planetary gear is connected to the output shaft of the engine; the second rotary element, as acting a reaction against the first rotary element, is connected to the motor-generator; and the third rotary element is connected to an output member for transmitting the drive power to wheels. The controller includes mode switching capability for switching the mode when the battery is in an ordinary state or in a low charge state, to a power split mode, in which the motor-generator outputs a reaction torque against the output torque of the engine so that the connecting/releasing mechanism can rotate the first, second and third rotary elements individually and, when the battery is in a full charge state, to a parallel hybrid mode, in which the motor-generator adds a torque to the output torque of the engine so that the connecting/releasing mechanism can rotate the first and second rotary elements together.

摘要： A lubricating apparatus, for a friction engagement element that engages a rotatable member with a case includes a hub connected to the rotatable member, friction members disposed between the hub and the case, a hydraulic servo for engaging the friction members, and an oil passage for supplying lubricant from the case to the friction members. A discharge opening of the oil passage is formed at a position which is radially inward of the friction members and which is axially to a side of the friction members. The discharge opening is directed toward the friction members. A weir member for restricting escape of lubricant in the axial direction through a gap between the hub and the friction members is provided at the other axial side of the friction members. Therefore, the axial escape of lubricant exiting the friction members can be prevented by a non-contact leakage restriction that does not cause drag resistance. The radially outward stream of oil between the friction members is secured, and the friction members can be reliably cooled to remove heat generated by slip control of the friction engagement element.

摘要： An automatic transmission control apparatus includes a continuously variable transmission (CVT) which, in turn, includes a primary pulley, a secondary pulley, a belt stretched between the primary pulley and the secondary pulley. The control apparatus further includes a pinching pressure generator for generating a pinching pressure on the belt, a travel environment all detector for detecting the travel environment of a vehicle, a torque variation estimator for estimating the transmission torque variation during travel, and a pinching pressure changer for changing the pinching pressure based on the estimation. The pinching pressure is prevented from constantly increasing because the transmission torque variation during travel is estimated, and the pinching pressure for the belt is changed based on the estimation. Accordingly, the torque transmission efficiency can be increased, and the fuel efficiency can thus be improved.
