4 HISTORY 1993 First Formula One Engine Control System 1999 McLaren win Constructors Championship Using the TAG Present McLaren Applied Technologies Sole supplier to IndyCar 2012 Present McLaren Applied Technologies Sole supplier to NASCAR 2014 Formula E Using M.A.T. E-motor, MCU & TAG- 400i TAG Electronics Founded Ron Dennis identifies the power of real-time electronics in motorsport 1995 McLaren F1 wins Le Mans 24HOURS TAG-312 Engine controller 2010 Diversification into Aviation Present McLaren Applied Technologies Sole supplier to Formula One 2013 McLaren P1 launched Using M.A.T. E-motor & MCU

5 Simulink for automatic code generation GDE TAG-210

6 6 Challenges 1999 MATLAB R10/R11 had limitations Simulink Coder (RTW) customisation/optimisation Limitations of Simulink blockset Multiple developers Multiple model files (no model ref) Multiprocessor system Separate binaries per processor Processor loading Ease of moving code between rates Rapid development cycle Days or hours between releases Regulatory constraints FIA code inspection

20 20 Formula One Version History 1999 R10/11 Extensive modification of Simulink code generation Map blocks not usable No function call block No expression folding optimisation No CSC support (storage class determine from parameter name) 2004 R13SP1 Significant difficulty in upgrading GDE started from scratch existing models ported Code generation optimisations now supported CSC support for storage types 2011 R2009bSP1 Upgrade straightforward Significant improvements in generated code Doubled available processing time 2016 R2015b Upgrade straightforward Reduced data copies GDE still providing support back to R2009b SP1

21 21 Formula One What Next? R2016a Compatibility issue arise Need to restrict backward compatibility Improve general compatibility Model referencing Variants Work with the MathWorks to align direction Multi processor support

22 22 Formula One Summary McLaren have been using Simulink for code generation of complete control functionality since 2000 Not just used for control systems Co-simulation (vtagserver) COTS rig systems (vtag-rt) Introduced this to all F1 teams in 2007, and subsequently to NASCAR, Indycar, LMP1 and FormulaE
