Apparatus for regulating vehicle transmission line pressure based on throttle opening or engine intake air quantity |
摘要 |
A hydraulic control apparatus for an automatic transmission of a motor vehicle, which has a plurality of gear positions that are selectively established by selective operation of hydraulically operated frictional coupling devices. The apparatus includes a pressure regulating device which receives a hydraulic pressure generated by a pressure source and generates a line pressure to be applied to the coupling devices. The pressure regulating device regulates the line pressure on the basis of the detected throttle opening angle of the engine when the vehicle is running in a transient state, and on the basis of the detected intake air quantity of the engine when the vehicle is running in a steady state.
