Abstract:
A control apparatus for a vehicle with a continuously variable transmission, having an acceleration requirement determining portion determining operator required acceleration, a first restricted accelerator operation amount setting portion setting an accelerating member restricted operation amount that increases with a running speed increase, when the determining portion has determined required vehicle acceleration, and a shift control portion controlling the transmission speed ratio on the restricted amount basis, the control apparatus having: a second restricted accelerator operation amount setting portion decreasing the restricted amount from a value immediately prior to an accelerating member rapid releasing action determination moment, at a rate lower than an accelerating member operation actual amount decrease rate after the rapid releasing action determination moment, and an upper limit stop processing portion to limit the restricted amount after a determination moment that the operator requires vehicle acceleration, the restricted amount is not larger than the actual operation amount.
