PURPOSE: To prevent regeneration of a run-through state in subsequent shifting by detecting a run-through state by comparing the shift time with the delay time. CONSTITUTION: A desired shifting time DST generated in a block 220, a measured shifting time MST, and a desired speed ratio Rdes are input to a block 222. Corresponding line pressure values are determined. The pressure difference (Pmst-Pdst) forms a pressure error output PE. When a run-through state is not detected, this pressure error is applied to a characterizing portion 228 of the control device via a logic gate 226, and generates a high pressure correction value PChi and a low pressure correction value PClo. On the other hand, in blocks 230, 232, a corresponding line pressure value is determined based on a limit delay time LDT. The difference (Pldt-Pmdt) generates a pressure error output PE. When a run-through state is detected, the control device operates so as to pass the run-through error, and a normal adaptive pressure control is nullified. |
