Engineer’s Assistant™   Engineer’s Assistant™ software develops statistical models about the performance of the car around it’s optimal configuration. The purpose is to model the unmeasured properties of the car-driver-track system and add these to the measured properties and develop feed-forward responses to changing ambient conditions and other uncontrolled factors. Engineer’s Assistant requires laps run under varying conditions to develop the models. This is best done with a simulation that closely approximates the results obtained on the track. When the statistical models have all the information they can use from the simulation, track runs are begun to learn where the actual observed results differ from the theoretical, what the causes may be, and what to do to improve the performance.
