<p>An automatic transmission control apparatus has a vehicle speed detector (Sn4), an accelerator pedal operation detector (Sn1), a brake pedal operation detector (Sn6), a clutch hydraulic servo (C-1) that is neutral-controlled, a brake hydraulic servo (C-1) that is hill holding-controlled, and a control device for controlling the fluid pressure supplies to the two servos. The control device selectively changes the start timing of the fluid pressure supply control. If it is determined that the vehicle is stopped and that the vehicle is not on an uphill, the control device causes a pressure reducing device and a pressure supplying device to simultaneously start reducing the fluid pressure supply to the clutch servo and supplying fluid pressure to the brake servo, respectively. If it is determined that the vehicle is on an uphill, the control device causes the pressure supplying device to start supplying fluid pressure to the brake servo and, after a predetermined time period, causes the pressure reducing device to start reducing the fluid pressure supply to the clutch servo. <IMAGE></p> |
