Calibrating ECUs – Trends and Effects on Development Methods and Tools
The developments and challenges of the next five to ten years in the area of measurement and calibration of ECUs will be determined by global trends and will involve several changes. Established work methods are frequently reaching their limits, and adoption of new approaches by companies is inevitable. Data-based calibration methods, "intelligent" data management with virtually transparent data exchange, and flexible integration of expert knowledge via apps, among other things, will supplement the work of the application engineer.

Calibration data management – A puzzle game no more
In ECU development, short innovation cycles and high cost pressure lead to a distribution of work, in which the software development process is separate from the process of adapting it to its desired behavior in the vehicle. In today's vehicles, tens of thousands of such calibration data values must be determined and managed and indeed for each individual vehicle variant. To avoid errors, quality standards are needed that have the same level as in the development of the actual software. This article discusses the requirements of tools for managing parameter values and presents a universal solution.
