Bill, looks like the link works: I see some chirp test documents (thanks for those) and an image of a 'vette being tasked with hauling hay.
I tried out the pulse steer method to tease out the freq response from a vehicle (again, Lagrangian mechanical vehicle model). results below (gifs @ 120 km/h).
Pulse steer - 10 deg SW over 2.5 sec with 10 sec test length
Chirp Steer - 10 deg SW with steer freqs from 1/10 through 2 Hz over 20 sec
Seems that in this scenario (and with this vehicle model), the pulse steer methodology correlates reasonably at low freqs but can't sense the info at the mid speeds. Obviously, this depends on the details put into the pulse definition. On the plus side, the size of the testing domain is reduced bigly.
A Sim should easily produce results looking like this. Both time based and complex frequency based (as shown).pulse Sufficiency.JPGpulse_40kph.JPGpulse_80kph.JPGpulse_120kph.JPG
See if this works now.
