Overturned rigidbody mel/expression

Maya
1

Good Day

I'm working on a rigidbody rig where I need to know whether or not the body has over turned in the world. Think of a vehicle where I need to know when to turn the driving impulse off. I first thought of an expression that followed the rotations within a range, e.g. between 70 degrees positive and negative in the x and z axis (y up world).

Obviously with maya's Euler rotations and generating the shortest solution I get unusable values where the vehicle is still upright with rotation values outside the range I'm looking for. I understand why this is so, but can't come up with a solution around it.

Beyond getting into matrix math (I suck) are there any other possible solutions?

Thank you

you could use the contact data on the top of the vehicle,, ie
if(vehicle.contactCount>0){
//i turned over

}

I need to kill the impulse before any such collisions would occur.
