METHOD FOR DETERMINING A VEHICLE PARAMETER OF A VEHICLE DATA SET OF A VEHICLE, AND USE OF THE VEHICLE PARAMETER AT A TEST BENCH

摘要

The invention relates to a method for determining the value of at least one vehicle parameter of a vehicle data set of a vehicle, a sub-component or a sub-system of a vehicle, as well as the use of a determined vehicle parameter for parameterising a simulation model (23) of a simulation (6) for carrying out a test on a test bench (10). For this purpose, from the vehicle parameters of the vehicle data set, a first number of parameters are established as input data or input parameters (E_i) in a task-specific manner, and a second number of parameters, preferably a complementary number to the first number, are established as output data or output parameters (A_j), and a vehicle database (1) is used, in which respective values of the input parameters (E_i) and values of the output parameters (A_j) are stored, in the form of vehicle data sets, for a number of validated vehicles that is sufficient for the purpose of model formation, in order to identify a dependence of the output parameters (A_j) on the number of the input parameters (E_i) in the form of a number of mapping models (Mx) (system identification, model formation), and the value of the number of the output parameters (A_j) is determined as the parameter of the vehicle data set based on said number of mapping models (Mx) and predefined values of the input parameters (E_i).
