  Let $B{ aut}_1X$ be the Dold-Lashof classifying space of orientable
fibrations with fiber $X$. For a rationally weakly trivial map $f:X\to Y$, our
strictly induced map $a_f: (Baut_1X)_0\to (Baut_1Y)_0$ induces a natural map
from a $X_0$-fibration to a $Y_0$-fibration. It is given by a map between the
differential graded Lie algebras of derivations of Sullivan models. We note
some conditions that the map $a_f$ admits a section and note some relations
with the Halperin conjecture. Furthermore we give the obstruction class for a
lifting of a classifying map $h: B\to (Baut_1Y)_0$ and apply it for liftings of
$G$-actions on $Y$ for a compact connected Lie group $G$ as the case of $B=BG$
and evaluating of rational toral ranks as $r_0(Y)\leq r_0(X)$.
