Pass the ajax variable per parameter of the laravel route

I need to pass a ajax variable as route parameter, but it is showing an error.

This is the error:

Too few arguments to function App\Http\Controllers\PermissaoController::status(), 0 passed and exactly 1 expected

This is the script:

<script type="text/javascript">
  $(document).ready(function() {
    $('#status_id').change(function(){
      var usuario = (location.pathname).split('/');
      var status = this.value;
  $.ajax({
    type: 'get',
    url: "",
    data: {status: status, usuario: usuario[2]},
    dataType:"json",
    success:function(html){
      $('#projeto_id').find('option').remove();
      $('#projeto_id').append('<option value="">Selecione...</option>');
      for(var i = 0; i< html.length;i++){
        $('#projeto_id').append('<option value="'+html[i]['id']+'">'+html[i]['titulo']+ '-' + html[i]['codigo']+ '</option>');
      }
    }
  })
})

})

This is my function in controller:

public function status($sd)   {
    $usuario = Usuario::where('id', $sd)->get();
    return $usuario;   
}

How can I do it?
