How to lock a vehicle to a curve normal in two dimensions?

Question

I realise that the question isn't a very good explanation so I've included a picture. I would like a vehicle (which is floating above the ground) to be locked to the curve of the ramp all the way around, and also to the yellow lines in order to stay perpendicular to the centre of the circle of which the ramp is the radius. alt text

I've kind of fixed the first part with this code from another thread:

  RaycastHit hit;

if

  (Physics.Raycast(transform.position, -curNormal, out hit)){

       curNormal = Vector3.Lerp(curNormal, hit.normal, 4*Time.deltaTime);

       Quaternion grndTilt = Quaternion.FromToRotation(Vector3.up, curNormal);

       transform.rotation = grndTilt * Quaternion.Euler(0, curDir, 0);

I tried to fix the issue with this code but it hasn't worked:

  Vector3 fromCentre = new

  Vector3(34.16f, 23.05f, 60.66f);

          Vector3 centreToShip = (transform.position - fromCentre);

          Vector3 shipNormal = (hit.normal);

          Debug.Log(shipNormal);

          //matches vehicle to normal of ramp (vertical)

          curNormal = Vector3.Lerp(curNormal, shipNormal, Time.deltaTime);

          Quaternion grndTilt = Quaternion.FromToRotation(Vector3.up, curNormal);

          transform.rotation = grndTilt;

I would really appreciate any help or direction with this.
