2 Made by Göteborg! sw development, a joint effort around the world Orchestrated in Göteborg 2

3 content Trends driving Automotive Software How we manage function and software development How we make all software work together ECU = Electronic Control Unit VECU = Virtual ECU PMT = Processes, Methods and Tools

8 So in this context, How do we develop software? And the mechanics And the engine And the electronics hw 8

9 Autosar the automotive sw arch standard Function specific applications Standardized formal description of SW components including I/F, CPU, memory, timing, etc. Auto generated middleware from xml-specs Standardized SW platform Configured by xml-specs of application swc:s and ECU descriptions. AR is de-facto for RT-systems. There is also a candidate for the Infotainment domain, called Genivi. 9

10 From customer function to sw components Engineering database and tool... generates xml for SWC and ECUs. 10

11 From sw component to integration and testing From function to SWC break down Physical env ECU / VECU AR SWC impl tool independant Virtual Env Physical car AR interface (autogen) Autosar RTE (autogen) ECU or SIM Virtual Vehicle SWC definition Physical plant HW ECU AR platform ECU HW Sim AR platform Generic HW Virtual plant HW 11

12 Virtual vehicle architecture VVA Besides a sw architecture we need a virtual vehicle architecture Model fidelity accurate enough to also evaluate mechanics! Separation of plant models and controllers (reusability) Common architecture for MIL, SIL, HIL, rigs Complete vehicle view; physical and functional oriented Support for different simulation environments and tools enabling multi-domain simulation 12

13 One common virtual vehicle 2/13/ MADE BY GÖTEBORG - THE SOFTWARE INSIDE THE ALL NEW XC90, MARTIN NILSSON, VOLVO CARS, MARTIN.P.NILSSON@VOLVOCARS.COM,

14 Integration management Structural approach to define test environments in terms of sw components and physical plant models. Layers of backlogs to control and manage weekly deliveries and maturity growth. Still huge improvements needed, to efficiently manage the increasing complexity without being infinite complicated. SAFe(?) As long as SW complexity increase, PMTs will always be a step behind. - And that s why it s so fun to work with. 2/13/ MADE BY GÖTEBORG - THE SOFTWARE INSIDE THE ALL NEW XC90, MARTIN NILSSON, VOLVO CARS, MARTIN.P.NILSSON@VOLVOCARS.COM,
