Relative versus absolute lateral acceleration?
Posted: Fri May 02, 2008 2:01 pm
Hopefully I'm not completely missing a built-in variable somewhere, but is there a way to calculate absolute lateral acceleration?
To clarify, the accelerometers on board the DL-1 move with the car and so always measure acceleration relative to the orientation of the car. Therefore, when you go around a banked turn, your measured lateral acceleration will be the same as when you are on a flat turn. The lateral acceleration in respect to the earth goes up, but that component is lost when the accelerometers bank. Can this acceleration easily be calculated in the software? Can I do it manually from speed and position data?
Thanks!
