METHOD FOR CONTROLLING A SET TORQUE TO BE APPLIED TO WHEELS OF AN AUTOMATIC TRANSMISSION FOR A MOTOR VEHICLE AND CORRESPONDING DEVICE

摘要

The invention relates to a method for controlling an automatic transmission of a power train for a motor vehicle, comprising a step for producing a first set torque signal to be applied to the wheels, which represents the wishes of the motor vehicle driver and which comprises two components: a static component (Cs) and a dynamic component (Cd_cond). The dynamic component (Cd_cond) of the set signal is filtered according to at least two predetermined thresholds that define at least three distinct filtering zones. A filter of the n order is used in the first and the third filtering zone and, in the second filtering zone, a maximum slope is imposed upon the dynamic component of the first set signal (Cd_cond), said maximum slope being adjustable according to predetermined input data.
