G-Force circle accuracy & body roll

[swbca3691]

This is a frivolous topic but Ill ask anyway . .

As a test when not driving, if you turn your phone 90 degrees left or right, the G-Force meter will read precisely 1.0 proving the phone's accelerometer is very accurate for that static situation.

When my vehicle is parked on a side-slope that approximates my vehicle's maximum body roll, the G-Force meter is somewhere between .1 and .2 G. So when the G-Force graphic shows 1.1G on a video, is it safe to assume the actual G's was about .8 or .9 because of the effect of body roll on the measurement ?

If that is true, and you are looking for something to do, maximum body roll could be added to the Vehicle description and be a progressive correction factor added to the G-Force graphic

Yes, body roll has an effect on measurements as described. I could use downforce measurements to adjust this... Not sure one gets too much noise... I will move this topic to Feature Requests

Three axis accelerometer support is also important for banked tracks. Of course then you'll probably need to do full sensor fusion including three axis rotation rates as well.
