  It is commonly known that the Fokker-Planck equation is exactly solvable only
for some particular systems, usually with time-independent drift coefficients.
To extend the class of solvable problems, we use the intertwining relations of
SUSY Quantum Mechanics but in new - asymmetric - form. It turns out that this
form is just useful for solution of Fokker-Planck equation. As usual,
intertwining provides a partnership between two different systems both
described by Fokker-Planck equation. Due to the use of an asymmetric kind of
intertwining relations with a suitable ansatz, we managed to obtain a new class
of analytically solvable models. What is important, this approach allows us to
deal with the drift coefficients depending on both variables, $x,$ and $t.$ An
illustrating example of the proposed construction is given explicitly.
