PCT No. PCT/EP92/01154 Sec. 371 Date Jun. 21, 1994 Sec. 102(e) Date Jun. 21, 1994 PCT Filed May 22, 1992 PCT Pub. No. WO93/00533 PCT Pub. Date Jan. 7, 1993.A method for controlling a preferably electrohydraulically actuated continuously variable transmission of a motor vehicle equipped with an internal combustion engine provides, in and ahead of curves, a retention of the last gear ratio set. The gear-ratio determination is initiated when the accelerator pedal is released rapidly in coasting operation. The gear transmission determination is suspended as soon as, after expiration of a time interval following recognition of acceleration, no curve is being traversed. If, during expiration of the time interval, coasting operation is detected again, the gear transmission determination is maintained for an additional time interval. Upon termination of the gear-ratio determination, a relatively slow adaptation of the gear ratio to the setting corresponding to the control curve RKLj takes place.
