PROCESS FOR EVALUATING A ROAD LAYOUT FOR AN AUTOMATIC GEARBOX

摘要

The invention relates to a process for evaluating a road layout for an automatic vehicle gearbox. Said process has the following stages: 1) determination of transverse acceleration (a_Quer) of the vehicle on the basis of measured wheel speeds (n_Rad) for the purpose of evaluating bends; 2) testing to check whether a first cornering process has occurred, and if it has, starting of a predetermined period (T) in a processing operation (S3); 3) a theoretical driver-type value (FT_Soll) and a first increment (INKR_O) between said theoretical value and an actual driver-type value (FT_Ist) on the basis of the vehicle transverse acceleration (a_Quer) and a vehicle speed (v_F); 4) in a differentiating operation (S6), to determine whether a second cornering process is occurring during the predetermined period (T), testing to check whether the period (T) has finished, and if it has not, a processing operation (S8) is activated to determine a second increment (INKR) which is weighted in relation to the first increment (INKR_O) with a factor (A) related to a completed period of the predetermined period (T); 5) determination, on the basis of the second increment (INKR), of a gear-change characteristic (SL) from a plurality of characteristics each associated with a particular driver type.
