    You can take the dot product (with 
    Vector3.Dot()
    ) of whatever you consider "forward" (perhaps 
    transform.forward
    ?) and the 
    .velocity
    vector out of the Rigidbody.

    If it is positive, you are going forward, otherwise backwards.

    This is the nitty gritty on dot products:
