subfigure \autoref

Question

I am trying to redefine the subfigure \autoref, but have not been successful. Below is example code for the figure. I am using the acticle documentclass and the subcaption package.

\begin{figure}[H]
  \centering
  \begin{subfigure}{.48\linewidth}\centering
    \includegraphics{figa.eps}
    \caption{atest}
    \label{a}
  \end{subfigure}\hspace{3mm}
  \begin{subfigure}{.48\linewidth}\centering
    \includegraphics{figb.eps}
    \caption{btest}
    \label{b}
  \end{subfigure}
\end{figure}

I tried to redefine the autorefs using the following

\let\orgautoref\autoref
\providecommand{\Autoref}
        {\def\figureautorefname{Figure}%
         \def\subfigureautorefname{Panel}%
         \orgautoref}
\renewcommand{\autoref}
        {\def\figureautorefname{figure}%
         \def\subfigureautorefname{panel}%
         \orgautoref}

but it did not work. How do I change the autoreference from displaying "figure 1a" to "panel a"?

Two possibilities came into my mind:

1. Redefine \p@subref which will be prepend to every reference typeset with \subref
2. Define and use your own \subref format

Here comes an example code which shows both methods:

\documentclass{article}
\usepackage[demo]{graphicx}
\usepackage{subcaption}
\usepackage{hyperref}

\DeclareCaptionLabelFormat{panel}{panel~#2}
\DeclareCaptionLabelFormat{Panel}{Panel~#2}

\begin{document}

\begin{figure}
  \centering
  \begin{subfigure}{.48\linewidth}\centering
    \includegraphics{figa}
    \caption{atest}
    \label{a}
  \end{subfigure}\hspace{3mm}
  \begin{subfigure}{.48\linewidth}\centering
    \includegraphics{figb}
    \caption{btest}
    \label{b}
  \end{subfigure}
\end{figure}

\makeatletter
\renewcommand\p@subref{Panel}
\subref{a}
\makeatother

\captionsetup{subrefformat=Panel}
\subref{a}

\captionsetup{subrefformat=panel}
\subref{a}

\end{document}

P.S.: Please post a minimal but compilable example next time so potential helpers have a document to play around with. I you don't do it, every potential helper has to do this first.

Without seeing your .tex-File I suggest to use \usepackage{subfig}, then you can use \newcommand{\subfigureautorefname}{\figureautorefname} to make \autoref work with \subfloat. I can't recall where I got this snippet from (probably from tex.SE), but anyways; it has worked fine for me.
