Transmission control units are often developed and calibrated for dozens or hundreds of vehicle variants. Not every possible variant is physically realised during development. Even the simulation of all variants on a HiL becomes infeasible with growing number of variants, since at least the control unit must then be physically realised and integrated into the HiL system. In such variant-rich cases, simulation of the entire system, including the control unit, becomes particularly attractive. Daimer, QTronic and Vector describe how Mercedes-Benz currently uses virtual ECUs to validate transmission control software for about 200 variants of the Sprinter series in a highly automated way on Windows PC.

Validation of 200 Variants

Mercedes-Benz Vans of the Sprinter series are available as box wagon, station wagon and pickup, for four- and six-cylinder diesel engines also with seven speed automatic transmission 7G-Tronic Plus. Maximal vehicle payload and transmission ratio of the rear axle can...
