Keywords: TCU, Optimization, AVLCRUISE, Data-management
The optimization of the automatic gearbox from the software point of view is considered to be as important as the optimization of the functioning process itself. The software has to take into account all the necessary and unnecessary information that is provided by the ECU for the TCU. If the software of the TCU is not updated to be able to make decisions that are correct for the driver, for the safety of the vehicle and for the transmission itself the entire power train unit has to suffer by poor data management. If the information provided by the ABS and by the ESP, information that are in strict connection with the safety of the vehicle are not correctly treated by the TCU there is a possibility of miss-function of the entire power train unit. Optimizing the data management is vital in the virtual environment of the TCU control software.
