Arrangement for controlling automatic gearboxes has controller that changes initial working pressure value in agreement with drive force during transition period between coupling states |
摘要 |
The arrangement has a working pressure controller (120,122) that produces a control signal changes the initial value of the working pressure in agreement with the drive force during the transition period between the fluid coupling state and the direct coupling state.
