Finding the optimized set of ECU-parameters for top vehicle performance

ECU software is parameterized so that the behaviour of control and diagnostic functions can be easily adapted to a variety of system variants or vehicle models. This happens by calibrating or modifying the characteristic values of function algorithms, without the need to change calculation routines.

ETAS hardware and software products form an integral part of the development process. They assist engineers in everything from developing application software for electronic control units (ECUs) to integrating automotive electronic systems in the vehicle. Our portfolio includes a variety of solutions for a state-of-the-art calibration process, from measurement modules to calibration tools.

ETAS’s portfolio covers typical engine calibration tasks, including:

• Optimizing base engine parameters like injection, ignition, and valve timing for power, torque, fuel consumption, and emissions under various conditions.
• Parameterizing algorithms to calculate key engine values such as torque, air and fuel mass, and emissions.
• Optimizing drivability from idle control to balancing sportiness and comfort.
• Parameterizing safety-related functions like vehicle dynamics control.
• Refining and validating calibrations under realistic environmental conditions during test trips.
