6 Testing Tester Data Tester diagnostic protocol ODX-C/CS ODX-D ODX-V 6

7 Tester Testing Simple Network Gateway CAN LIN FlexRay MOST Ethernet 7

8 Testing Communication Access for all ECUs: ODX-V Entire tester data ODX-C/CS ODX-D ODX-V ECU 1 data ECU 2 data ECU n data ODX-C/CS ODX-C/CS ODX-C/CS ODX-D ODX-D... ODX-D ODX-V communication access for all ECUs 8

9 Testing ODX-V Data Model ODX-V ODX-D VEHICLE - INFO - SPEC * 1 1..* INFO - COMPONENT vehicle identification data VEHICLE - INFORMATION 1 * LOGICAL - LINK * * FUNCTIONAL - GROUP BASE - VARIANT ODX does not use the term ECU. BASE-VARIANT is always the ECU. FUNCTIONAL-GROUP has functional addressable services for a group of ECUs. A LOGICAL-LINK describes the communication access. For each ECU and provided diagnostic protocol FUNCTIONAL-GROUP GATEWAY LOGICAL-LINK always for gateways. XOR = ECU a (MEMBER-/GATEWAY-) LOGICAL-LINK must exist. 9

10 Testing COMPARAM-SUBSET for UDS 7 UDS COMPARAM-SUBSET ISO_14229_3 ISO_14229_5 6 Data Diagnostics on CAN Diagnostics over IP ISO_15765_2 ISO_13400_2* 2 1 CAN Ethernet IEEE ISO_11898_2_DWCAN ISO_11898_3_DWFTCAN SAE_J2411_SWCAN IEEE_802_3* 10

11 Testing COMPARAM-SUBSET for OBD II COMPARAM-SUBSET 7 OBD II ISO_15031_5 6 Data Diagnostics on CAN DoK-Line , -5 ISO_15765_4 ISO_9141_2 ISO_14230_4 2 1 CAN K-Line ISO_11898_2_DWCAN ISO_9141_2_UART ISO_14230_1_UART 11

12 Testing COMPARAM-SPEC A COMPARAM-SPEC contains PROT-STACKs ODX-C/-CS Each PROT-STACK references the relevante commmunication parameters for an use case like UDSonCAN, KWPonCAN etc. COMPARAM SPEC COMPARAM SUBSET APPLICATION PROT - STACK COMPARAM SUBSET TRANSPORT LAYER COMPARAM SUBSET PHYSICAL LAYER ODX-C = COMPARAM-SPEC ODX-CS = COMPARAM-SUBSET 12

13 Testing Services and Jobs in ODX-D D = DIAG-LAYER-CONTAINER FUNCTIONAL GROUP A DIAG-LAYER-CONTAINER contains DIAG- LAYER(s) A DIAG-LAYER may contain DIAG-SERVICEs (diagnostic services) BASE VARIANT = ECU SINGLE-ECU-JOBs (diagnostic jobs) ECU-VARIANT 22 I D 62 I D Da ta 13

15 Reprogramming Flash Session Reprogramming Session := smallest flashable unit ODX-F Session ODX-F splits session in SESSION-DESC and SESSION SESSION-DESC * 1 SESSION 15

16 Reprogramming Flash Data SESSION-DESC * 1 SESSION Download with Flash Job Upload with Flash Job Priority (optional) SESSION ordered * 1..* DATA-BLOCK * 1 FLASH-DATA e.g.: Initial Programming (App & Data) Update (Data) Segment Info (source and target address) Security Info (Checksum & Signature) Intel Hex or Motorola-S or Binary Encryption Info Compression Info 16

17 Reprogramming Process Safe Flash Data ODX-F Process Safe Flash Data ODX-F Manufacturing After Sales ODX-C/CS ODX-C/CS ODX-D Flash Job Flash Job ODX-D ODX-V ODX-V 17

23 Vehicle Function Data Example Function: Central Lock ODX-FD ODX-FD (FUNCTION-DICTIONARY) is an attachement for ODX-D. After Sales ODX-C/CS a documentation for a vehicle function. ODX-D ODX-V ODX-FD ODX-D ODX-D ODX-D ODX-D Door ECU Front Left Door ECU Front Right Door ECU Rear Left Door ECU Rear Right 23

24 ODX Files PDX ODX files In any case one ODX file contains exactly one sub model (e.g. ODX-V, ODX-D, ODX-E,...) File extensions for each category are suggested ODX PDX files Contains one or several ODX files. Zip file Intention: PDX represents ECU or vehicle Zip file, but with extension.pdx PDX May contain additional files: Picture, text, java code Must contain a file index.xml which contains the content of the package. ODX + Index.xml 24

25 ODX Files Data Is Close to Process Responsibility Technology manager at OEM COMPARAM SPEC PROT - STACK FUNCTIONAL GROUP Vehicle and/or technology manager at OEM ECU data BASE VARIANT Project Manager at OEM and supplier ECU-VARIANT Supplier 25
