HomeLink – Standardization of Software • General functionality • LIN protocol • Signal based interface • Diagnostics • General • Identification Content • Identification Protocol HomeLink Topics Working Group HomeLink 10.03.2010

HomeLink – Standardization of Software General Functionality • Current Situation Additional OEM specific features in all projects • Audi – MMI, interface to blinker and external switchboard • Daimler – Security feature, new HMI with 3 color LED • BMW – Flashing of additional manufacturer keys • Proposed Solution • Simplification of functions – e.g. HMI without BAP • Add possibility to deactivate OEM specific functionality, so that remaining functionality is not blocked HomeLink Topics Working Group HomeLink 10.03.2010

HomeLink – Standardization of Software General Functionality • Impact • Significant changes on all participating ECUs (Master, Head unit...) needed to get rid of proprietary protocols • Efforts necessary to create and keep functionality compatible between OEMs • Memory usage and code complexity increased, when specific deactivatable functionalities are integrated HomeLink Topics Working Group HomeLink 10.03.2010

HomeLink – Standardization of Software LIN Protocol • Current Situation • LIN 1.3, 2.0 & 2.1 are used • Different baud rates - 9600 and 19200 Baud • Proposed Solution • LIN 2.1 with 19200 Baud • Impact • HomeLink not usable with LIN 1.3 Master • Usable with LIN 2.0 master with slight limitations: Slave node configuration services not available to change frame IDs  Problems adapting the standard configuration to the OEM networks HomeLink Topics Working Group HomeLink 10.03.2010

HomeLink – Standardization of Software Signal based interface • Current Situation • Communication matrixes differ between Audi, Daimler & BMW in various ways: Basic concept (Rx/Tx or Broadcast), structure, IDs, signals and contents • Possible Solution • Definition of a new communication matrix as common basis for all OEMs • Adaptation of frame identifier to car network possible via node configuration • Impact • Structure of data exchanged with HomeLink cannot be specific to an OEM anymore • Modifications needed on all networks where OEM specific communication is replaced by standardized software HomeLink Topics Working Group HomeLink 10.03.2010

HomeLink – Standardization of Software Signal based interface • Possible Solution • Common Rx frame contains... • State of external buttons • Country code • Enable signal • Direct control commands (Default Mode, Delete,...) – May be used for HMI control • Common Tx frame contains.... • State of internal buttons • State of HomeLink (training succeeded, timeout, ....) – May be used for HMI control • Control of external LED • Country code • Fault signals HomeLink Topics Working Group HomeLink 10.03.2010

HomeLink – Standardization of Software Signal based interface • Possible Solution • Rx Frame HomeLink Topics Working Group HomeLink 10.03.2010

HomeLink – Standardization of Software Signal based interface • Possible Solution • Tx Frame HomeLink Topics Working Group HomeLink 10.03.2010

HomeLink – Standardization of Software Signal based interface • Impact • Differences for Daimler • Only one single activation signal for HomeLink – active / not active • Security functionality needs to be redefined so that it fits into new concept • No possibility to have a second or third LDF • Fault signals to be standardized • Country code to be changed via signal instead of diagnostic service • Differences for Audi • BAP data to be replaced by state and control signals – intelligence to be moved to HMI system • Acknowledgement from vehicle blinker and switchboard LED to be removed HomeLink Topics Working Group HomeLink 10.03.2010

HomeLink – Standardization of Software Signal based interface • Impact • Differences for BMW • Structure of fault signals will be redefined • Control of HomeLink via signals instead of code block update • Code block update function to be dropped or redefinition needed HomeLink Topics Working Group HomeLink 10.03.2010

HomeLink – Standardization of Software Diagnostic - General • Current Situation • Diagnostics mainly for identification - differences in content and protocol • No activities for standardization on OEM side • Diagnostic transport layer not supported on all OEMs • Additional functionality at Daimler to write and read country code, security code,... via Diagnostics HomeLink Topics Working Group HomeLink 10.03.2010

HomeLink – Standardization of Software Diagnostic – Identification Content • Current Situation • Common Information • Partnumber • BMW – 10 digits BCD – „0009146260“ • Daimler – 10 chars ASCII – „2048201997“ • Audi – 11 chars ASCII – „AH0907410 “ • Software Version • BMW – 4 digits BCD – „0001“ • Daimler – 3 bytes hex – „09.22.00“ • Audi – 4 chars ASCII – „0010“ • Hardware Version,... HomeLink Topics Working Group HomeLink 10.03.2010

HomeLink – Standardization of Software Diagnostic – Identification Content • Current Situation • Additional Information • Audi • Serial Number • System name • Hardware Part number • Daimler • Diagnostic Version • Production Date • BMW • Serial Number HomeLink Topics Working Group HomeLink 10.03.2010

HomeLink – Standardization of Software Diagnostic – Identification Content • Proposed Solution • Definition of a basic set on information • Content in OEM specific format written in production • Impact • Size of content needs to be fixed for all OEMs. Testers / Diagnostic master needs to be able to work with this • Information not part of the basic set would mean a deviation • SW Version needs to be placed in NVM to be adaptable to OEM requirements HomeLink Topics Working Group HomeLink 10.03.2010

HomeLink – Standardization of Software Diagnostic – Identification Protocol • Current Situation • Different identifier and services • Example partnumber • Audi – Read Data by ID (0x22) – ID 0x0643 • Daimler – Read Data by ID (0x22) – ID 0xF151 • BMW – Read by ID (0xB2) – ID 0x29 • Proposed Solution • Definition of OEM independent Ids available on service 0x22 HomeLink Topics Working Group HomeLink 10.03.2010

HomeLink – Standardization of Software Diagnostic – Identification Protocol • Impact • Overlapping of IDs with other ECUs possible • Deviation from OEM specific diagnostic standards – problems in accessing the information in the tester / diagnostic master HomeLink Topics Working Group HomeLink 10.03.2010
