摘要： A control apparatus for an automatic transmission includes an operational condition detecting unit for detecting a vehicle operational condition, a slope detecting unit for detecting a road surface slope, and a shift characteristic selecting unit for selecting one of a plurality of shift maps preliminarily set according to the road surface slope. The control apparatus further includes an acceleration/deceleration calculating unit for calculating an acceleration or deceleration from the degree of increase or decrease in vehicle speed per unit time, a deceleration shift characteristic for deciding a gear position according to the deceleration and the vehicle speed, and a brake detecting unit for detecting a brake operation. When the road surface slope is determined to be a downhill slope and the brake operation is detected, the selected shift map is changed to the deceleration shift characteristic and the gear position is decided according to the deceleration shift characteristic.

摘要： A control device for a vehicle for cooperatively controlling the engagement of a lock-up clutch and the conditions of fuel cut. When the rotational speed of an input shaft of a transmission becomes greater than a predetermined value during deceleration running in the condition where a throttle valve is fully closed, the lock-up clutch is engaged. Thereafter, the fuel cut start engine speed increased by a predetermined value is changed to a normal fuel cut start engine speed, at which the fuel cut is started. Accordingly, engine brake can be produced at a lower vehicle speed as compared with the prior art.

摘要： A multiple disc clutch apparatus can comprise a plurality of driving clutch plates spline-fitted axially slidably on an input member rotated by a driving source, a plurality of driven clutch plates arranged alternately with the driving clutch plates and spline-fitted axially slidably on an output member, a clutch piston having one surface facing toward an oil pressure chamber and the other surface facing toward the driving clutch plates or driven clutch plates and adapted to be displaced toward a clutch-on side by supplying oil to the oil pressure chamber to pressure-contact the driving clutch plates and driven clutch plates each other so as to transmit a driving force of the input member to the output member and also adapted to be returned toward a clutch-off side by discharging the oil in the oil pressure chamber to separate the driving and driven clutch plates and from each other so as to cut off the transmission of driving force from the input member to the output member. A valve can be pass through the one surface and the other surface of the clutch piston and can be adapted to occupy a closed condition for preventing the oil from flowing from the oil pressure chamber to the side of other surface of the clutch piston when the clutch apparatus is clutched-on and also adapted to occupy an opened condition for allowing flow of air from the side of other surface to the oil pressure chamber when the clutch apparatus is clutched-off. One or more recess for weight reduction can be formed on the one surface of the clutch piston at a position near to the outer circumference “a” further radially outward than the valve.
