  • Development of a Calibration Tool Using CCP and XCP on CAN Bus
    Development of a Calibration Tool using CCP and XCP on CAN Bus Master Thesis Submitted in Fulfilment of the Requirements for the Academic Degree M.Sc. Dept. of Computer Science Chair of Computer Engineering Submitted by: Satyesh Shivam Student ID: 386595 Date: 14.11.2016 Supervising tutor: Prof. Dr. W. Hardt External Supervisor: Dipl-Ing Billand Dirk (Bosch Engineering Gmbh) Abstract Testing of the Electronic Control Unit is a very important step before delivering the software to customer. Due to increasing complexity in the requirements and the timing constraints, it is needed that the testing should be proper and on time. To meet the timing constraints it is needed to automate the entire process of testing. Although the current testing tool support the automation process, it is very slow. In this thesis a new tool has been developed which will support calibration using CCP and XCP on CAN bus. Secondly, the tool will also provide the feature of automation, where user can write their own script to test the ECU. This will make the entire process of testing very fast. Finally both the solutions will be compared with respect to time for deducing the final conclusion. Keywords: CCP, XCP, ECU Testing, Calibration, Design Patterns Acknowledgements I would like to show my greatest appreciation to Prof.Dr.Wolfram Hardt for giving me an opportunity to do my thesis under his guidance. I am grateful to Mr. Dirk Billand for being my supervisor and providing constant support in developing my thesis from all the directions. I appreciate the feedback offered by Mr.

  • Increasing Efficiency in ECU Function Development for Battery Management Systems
    DEGREE PROJECT IN INFORMATION AND COMMUNICATION TECHNOLOGY, SECOND CYCLE, 30 CREDITS STOCKHOLM, SWEDEN 2016 Increasing efficiency in ECU function development for Battery Management Systems SHIVARAM SINGH RAJPUT KTH ROYAL INSTITUTE OF TECHNOLOGY SCHOOL OF INFORMATION AND COMMUNICATION TECHNOLOGY Increasing efficiency in ECU function development for Battery Management Systems Master of Science thesis in Embedded Systems (30 ECTS credits) at the school of Information and Communication Technology KTH Royal Institute of Technology Stockholm, Sweden October 2016 by, Shivaram Singh Rajput Supervisors: Christian Fleischer Advanced Battery Technology, NEVS Yuan Yao ESY ELEKTR. O INBYGGDA SYSTEM, KTH Examiner: Zhonghai Lu ESY ELEKTR. O INBYGGDA SYSTEM, KTH ABSTRACT In the context of automotive industries today, the focus of ECU function development is always on finding the best possible combinations of control algorithms and parameter. The complex algorithms with broad implementation range requires optimal calibration of ECU parameters to achieve the desired behaviour during the drive cycle of the vehicle. With the growing function complexity of automotive E/E Systems, the traditional approaches of designing the automotive embedded systems are not suitable. In order to overcome the challenge of complexity, many of the leading automotive companies have formed a partnership in order to develop and establish an open industry standard for automotive E/E architecture called AUTOSAR. In this thesis, toolchain for ECU function development following AUTOSAR standard and an efficient measurement and calibration mechanism using XCP on CAN will be investigated and implemented. Two toolchains will be proposed in this thesis, describing their usage in different stages of ECU function development and in calibration.
