Analysis

SimRacingAnalysis: MATLAB software for reverse engineering car parameters from ACC. It can extract sprung mass properties like CoG, estimate downforce and drag as a function of speed, ride heights, and wing/splitter settings, all from a serious of maneuvers performed in game. It is built on top of my VehicleAnalysis repo.

SDMotecWorkspace: MoTeC i2 workspace designed to be compatible with multiple simulators (ACC and iRacing currently), and provides a large number of calculatioe metrics/graphs for things like:

• Drive inputs (throttle, brake, steering), instantaneous and lap average application rate

• Slip angle, slip ratio, oversteer angle

• Tire loading distribution

• Acceleration during phases (e.g. braking, aero dominant, etc)

• Front and rear roll gradients, roll angles, and roll ratio

• Damper velocity histograms

• Ride height and rake angle

• Tire temperature and pressure biases, brake temperature rates

• Fuel consumption rate

• Hybrid system deploy rates, charge rates, braking regen efficiency

• etc.
