OEM Conformance Tests for CAN FD

Transcription

1 Vector CAN FD Symposium 2017 V

2 Agenda Scope of OEM Conformance Test Motivation for Test Package Test Package Components Vector Solutions for CAN FD Example: CANoe Test Package VAG Summary + Outlook 2

3 Scope of OEM Conformance Tests Basic physical layer check Test method: measurement with oscilloscope network integration test Sending behavior (cycle times, CAN IDs, DLC, ) Wakeup/sleep behavior + network management protocol (if applicable) Main test method: observing bus traffic stimulation test Power supply Ignition clamp Message events (timeout, DLC, ) Signal events (ignition signal, CRC, message counters, error values, ) Bus errors Main test method: feedback via diagnostic trouble codes Not covered Application functionality Conformance to network protocol usage of certified transceiver + controller assumed 3

4 Motivation for Test Package Characteristics Ready-to-use generic test implementations Automated test operation for minimum testing effort Possibility for repeatable testing that accompanies development Test coverage as large as possible Justifiable costs for test hardware + software Benefits on supplier side High quality tests > Widespread usage > Close cooperation between OEM and test package responsible Greatly reduced effort for own tests Earlier detection of problems cost reductions Benefits on OEM side Less testing effort due to higher initial quality Less effort to validate supplier tests Potentially independent test implementations cost reductions 4

5 Test Package Components (without I/O) Power Supply Controllable power supply + ignition Under- and overvoltage Voltage disturbance sequence (e.g. spike) 5

6 Test Package Components (Partial) Remaining Network Simulation Sending (+ receiving) of messages Comprehensive control and fault injection, e.g. Triggering and suppression of messages Setting of signals (without I/O) Network protocol (e.g. CAN FD) Power Supply 6

7 Test Package Components (Partial) Remaining Network Simulation (without I/O) Network protocol (e.g. CAN FD) Digital/analog disturbances Disturbance Versatile/fast triggers Power Supply 7

8 Test Package Components (Partial) Remaining Network Simulation Diagnostic Comm. Read / clear DTCs Handling of diagnostic session (without I/O) Network protocol (e.g. CAN FD) Power Supply Disturbance 8

9 Test Package Components (Partial) Remaining Network Simulation Diagnostic Comm. (without I/O) Network protocol (e.g. CAN FD) Oscilloscope Disturbance Power Supply Voltage signal levels/edges Eye diagram 9

10 Test Package Components (Partial) Remaining Network Simulation Diagnostic Comm. (without I/O) Network protocol (e.g. CAN FD) Oscilloscope Control + Reporting Power Supply Disturbance 10

11 Vector Solutions for CAN FD Control + Reporting Remaining Bus Simulation Diagnostic Communication CANoe with Test Feature Set + CAN FD interface (e.g. VN1630A) Power Supply VH1150 (I max 2.5A) VT7001A (I max 70A) Oscilloscope CANoe.Scope with additional hardware (e.g. Picoscope 5444B-034) Disturbance VH6501 (includes CAN FD interface) (coming soon) 11

12 Example: CANoe Test Package VAG Future standard setup for CAN FD CAN FD bus VH6501 USB I max 2.5A VH1150 USB Future extended setup for CAN FD CAN FD bus VH6501 USB I max 70A VT System ETH VT7001A + Controllable Power Supply 12

13 Example: CANoe Test Package VAG Test generation + Execution 13

14 Summary + Outlook Summary Both OEMs and suppliers profit from CANoe test packages CANoe Test Package VAG > Successful product since 2008 > Estimated number of end users worldwide: ~60 > Positive feedback from both Volkswagen AG and its suppliers > Roadmap > Version 4.0 (in work) > Support of CAN FD test specifications > Requires VH6501 and CANoe Main Release Service Pack Outlook Test hardware for 48V electrical system > CAN disturbance interface VH6501 (coming soon) > Power supply module VT7101 (planned) 14
