  The topcolor-assisted technicolor (TC2) model predicts the existence of the
charged top-pions ($\pi_t^\pm$), whose large couplings with the third
generation fermions will induce the charged top-pion production associated with
the bottom and anti-bottom quark pair at the CERN Large Hadron Collider (LHC)
through the parton processes $c\bar b \to \pi_t^+ b \bar b$ and $u\bar d(c\bar
s) \to \pi_t^+ b \bar b$. In this paper we examine these productions and find
that, due to the small Standard Model backgrounds, their production rates can
exceed the $3\sigma$ sensitivity of the LHC in a large part of parameter space,
so these processes may serve as a good probe for the TC2 model.
