See full text

The proposal is for a process for controlling a CVT of the bevel-pulley-belt type in which, on the occurrence of a wheel-locking drive situation, a converter bridging clutch is disengaged and at the same time a forward or reverse drive clutch is disengaged. The pressure level of the secondary pulley (3) is hereby raised and the transmission ratio of the CVT is changed in accordance with a predeterminable transmission ratio change and a predeterminable gradient.
