    摘要： When gear shift to second gear shift stage is completed and frictional engagement element is judged to be in slip state by slip state judging unit in a state in which input torque is input torque upper limit value, a value obtained by subtracting first predetermined amount from the input torque upper limit value is set as a decrease side input torque upper limit value. When next gear shift to the second gear shift stage is completed with the decrease side input torque upper limit value set and the frictional engagement element is not judged to be in slip state by the slip state judging unit in a state in which the input torque is the decrease side input torque upper limit value, a value obtained by adding second predetermined amount to the decrease side input torque upper limit value is set as a new input torque upper limit value.

    摘要： The purpose of the invention is to provide an automatic transmission devised to reduce manipulation discomfort between a forward first-speed and a reverse-speed while also minimizing any increase in scale of planetary gear sets. When the three rotational elements of each of the first to fourth planetary gear sets 2-5 are arranged on a common velocity diagram in dependence upon distances corresponding to teeth-number ratios of the first to fourth planetary gear sets 2-5, the respective rotational elements are defined as first to twelfth elements in order of arrangement on the common velocity diagram. The first planetary gear set 2 is configured to integrally rotate by a first clutch 8. The first element 22 is coupled with the fifth element 34. The second element 24 is configured to be locked through a first brake 6 to a stationary section 13 and configured to be coupled through a second clutch 9 with the ninth element 41. The third element 21 is coupled with the input shaft 1. The fourth element 32 is configured to be coupled through a third clutch 10 with the ninth element 41. The sixth element 31 is locked to the stationary section 13. The seventh element 42 is configured to be locked through a second brake 7 to the stationary section 13. The eighth element 44 is coupled with an output shaft 12. The ninth element 41 is coupled with the twelfth element 51. The tenth element 52 is configured to be coupled through a fourth clutch 11 with the output shaft 12. The eleventh element 54 is coupled with the input shaft 1.

    摘要： A hydraulic control device includes: a mechanical oil pump (O/P) that is driven by a motor/generator (M/G) and that generates a first hydraulic pressure (P1); an electric oil pump (M/O/P) that is driven by a sub-motor (S/M) and that generates a second hydraulic pressure (P2); and a controller (10). When a demanded drive force from a driver is generated while in a low-vehicle-speed region which is lower than a first vehicle speed (V1) at which the output of the mechanical oil pump (O/P) becomes unstable, the controller (10) controls the electric oil pump (M/O/P) such that the second hydraulic pressure (P2) becomes larger than a compensative hydraulic pressure (Pα) found by subtracting the first hydraulic pressure (P1) from a necessary hydraulic pressure (Pne) determined in accordance with the demanded drive force.

    摘要： An oil pressure control device for a vehicle is configured such that, when switching from an oil pressure supply by means of a mechanical oil pump (O/P) driven by a motor/generator (MG) to an oil pressure supply by means of an electric oil pump (M/O/P) driven by a sub-motor (S/M), a supply ratio of oil supplied from the mechanical oil pump (O/P) and a supply ratio of oil supplied from the electric oil pump (M/O/P), are adjusted based on an oil pressure difference between a first oil pressure (P1) and a second oil pressure (P2), via first and second flapper valves (101a), (102a). When the first oil pressure (P1) becomes less than or equal to a pump drive threshold (P O/P ), an increase in the second oil pressure (P2) is initiated, and the first oil pressure (P1) and the second oil pressure (P2) are made to match at a predetermined equilibrium oil pressure (P ba ) higher than a required line pressure (PL ne ).
