ABSTRACT

Today's automobiles contain several different electronic components networked together are responsible for monitoring and controlling the state of the vehicle. The vehicle's essential safety depends on the near real-time communication between these various Electronic Control Units (ECU's). Testing of the Electronic Control Unit is a very important step before delivering the software to the customer. ECU doesn't have an onboard debugger, and it becomes a tedious job for ECU testing and calibration. All the calibrate-able parameters are grouped into a special section of ECU memory called "calibration memory."  Calibration tools give the user access to this memory. So, there is a need for an interface that can serve this purpose. It might be possible that the user wants to do simultaneous calibration of multiple ECUs, which may have different calibration protocols. Therefore, there is a need for a solution that can be integrated into an automated setup. We propose a new tool called "Device Driver for CAN Calibration Protocol (CCP)" to support calibration using CAN bus. The tool will also provide automation, where users can read and write their scripts to test the ECU. It will make the entire testing process very fast.
