Calibration Development with Production Intent Electronic Control Units
William J. Allen · SAE technical papers on CD-ROM/SAE technical paper series · 2000
Automotive manufacturers and Electronic Control Unit (ECU) vendors have been struggling with the challenges of providing calibration development capabilities in the mass production intent ECU's while keeping the cost of the mass production ECU's and associated tools to a minimum. Delphi Delco Electronics Systems has been working with Motorola Semiconductor and Infineon to add this capability into new microcontrollers to allow the ECU calibration variables to be monitored and calibration constants to be changed in real-time on the production intent ECU's. This technology has been successfully introduced to ECU customers and has demonstrated a significant savings in tool costs and assisted in improving the accuracy of calibration constant data values.
