How to Create a Clutch System for an Attachment in Matlab-Adams Car Cosim?

I want to make ARB noneffective dependent on a state variable. Whether it should be active or nonactive, changing with the value of the state variable. It would be amazing to provide zero effect (for the specified joint) in Simulink, but I am open to any suggestions that are linked to Adams/Solver.

This is trivial and can be done in a multitude of ways. The easiest is to define the connection between left and right side of the clutch using a rotational SForce to emulate the clutch (and even the ARB itself if required).

The function would then be:

VARVAL(ARB_Active)*(-K_arb*AZ(M2,M1) - C_arb*Wz(M2,M1,M1))

and you can control the activity of the ARB by changing the solver variable ARB_Active between 0 and 1.

I prefer another facet of the mentioned multitude:

Using a GCON between two markers in the middle of the ARB that ususually would have been connected with a fixed joint.

Constraining them with a let's say spherical and a GCON with function = AZ(I/J)*Varval(on_off_variable) will make the torsional connection switchable via a state variable.
