Methodical Approach for Current Powertrain Requirements
New methods are required for efficiently achieving the development goals of future powertrains. APL describes the use of new tools based on genetic algorithms for the targeted parameter optimization and analysis of large amounts of data using syntactic and statistical pattern recognition. New processor and memory technologies increase the analysis performance of complex calculations and simulations and efficiently support the calibration process. ECU calibrations can already be prepared in offline applications as part of SiL (Software-in-the-Loop) studies and thus reduce the effort on the test bench or in the vehicle.
Requirements for the Calibration of Powertrains
In addition to the WLTP test cycle (Worldwide harmonized Light vehicles Test Procedure), with the introduction of the Euro 6d-temp legislation, the real driving emissions according to the RDE (Real Driving Emissions) test procedure must also be met for the homologation of new vehicle types. As reported in , APL has...
