Method for customizing the properties of a drive assembly in motor vehicles

Abstract

The object of the invention is to customize the properties of the drive assembly of motor vehicles comprising an intake system, an exhaust system, and/or an internal combustion engine. For this purpose, the mechanical properties of a serial drive assembly, the engine parameters efficiency and rotational torque, and the acoustics of the serial intake and/or exhaust system are stored in a database in an initial step. Furthermore, the construction features of the serial drive assembly that can be customized are stored in the database with their variation parameters and limitations. After varying at least one construction feature, the modifications of the engine parameters resulting therefrom are calculated and stored as a parameter difference. Likewise, the resulting changes of the acoustic features are calculated and stored as sound difference. Thereafter, the original values of the serial drive assembly are overwritten with the difference values and reproduced acoustically. If necessary, the steps from varying the construction features to the acoustic reproduction can be repeated over and over until the desired end result is obtained. The data transmission from the user to the database and back is done via Internet and/or Intranet.
