Highest measurement and calibration performance through cooperation of OEM, Tier1, μC, Tool-Supplier

Abstract

Due to the rapidly increasing complexity of software in engine control units, there is a demand for ever increasing measurement and calibration data rates and more comprehensive functions for development and calibration. At the same time, space for installing the measurement hardware is decreasing. The familiar methods based on bus protocols such as XCP on CAN and XCP on FlexRay are no longer sufficient, resulting in the need for connection of high-performance measurement and calibration hardware between the ECU and the measurement and calibration tool. There is a strong demand on the part of both vehicle manufacturers and ECU suppliers for solutions that use the XCP protocol standardized by ASAM with different transport protocols between the measurement and calibration hardware and the measurement and calibration tool. Because the XCP standard assumes that the ECU is connected directly to the measurement and calibration tool, the XCP standard must be expanded for this application. This presentation will describe how an innovative high-performance hardware device for measuring, calibrating, bypassing, rapid prototyping, and Flash programming can be connected to the existing measurement and calibration tool. The connection to the latest microcontroller generation (e.g. Freescale MPC57xx, Infineon Aurix, Renesas RH850) is realized for this using a standardized XCP-on-Ethernet interface.
