Automatic transmission control apparatus |
摘要 |
An automatic transmission control apparatus has an input clutch, a hydraulic servo for the clutch, a fluid temperature detector, an engine start detector, a range shift detector, and a control device for controlling the fluid pressure supply to the hydraulic servo. The control device raises the fluid pressure supply to the hydraulic servo on the basis of predetermined rising characteristics in normal operation. When it is determined that the shift has been performed for the first time since the start of the engine and it is determined that the fluid temperature is lower than a predetermined temperature, the control device rapidly raises the fluid pressure supply to the hydraulic servo up to the required engaging pressure.
