  • Patent number: 6835158
    Abstract: An automatic transmission has a first brake, a third brake and a hydraulic actuator for the third brake substantially axially aligned in sequence from rear to front in a radially outer area of the transmission. In addition, a first planetary gear unit, a first one-way clutch and a second one-way clutch are provided in an axial sequence from rear to front, in a radially inner area of the transmission. In this manner, component members are mounted with good spatial efficiency in both radial and axial dimensions. Furthermore, because a carrier of the first planetary gear is connected to a third brake through the first one-way clutch, the carrier can be reversely rotated by disengaging the third brake, enabling six forward speeds.

  • Patent number: 6760655
    Abstract: An automatic engine stop/restart-type vehicle and control method determine whether a vehicle is in a non-running range. The vehicle comprises: an engine; a transmission, an oil pump and a controller. The transmission has a coupling element that transmits an output torque of the engine. The oil pump supplies a hydraulic pressure to the transmission. The controller controls an output from the engine; controls the hydraulic pressure supplied to the transmission; and determines whether the engine is in an automatic stop state when a manually set mode of the transmission is shifted from a non-running range to a running range. A hydraulic pressure compensation procedure is performed to conform friction coupling characteristics of the coupling element and input characteristics of the transmission with each other if the controller determines that the engine is in the automatic stop state.

  • Patent number: 6716138
    Abstract: A condition for driving an electric oil pump is set. A turbine speed or an input speed of an automatic transmission is measured. A correction amount for a hydraulic pressure is calculated on the basis of the turbine speed obtained by reference to a relation between the turbine speed and hydraulic pressure, and a correction amount for a drive duty ratio of the electric oil pump which is required for generation of the corrected hydraulic pressure is calculated. The procedure is resumed after the procedure has been performed. The condition for driving the electric oil pump is updated on the basis of the correction amount for the drive duty ratio calculated.
