We study a one-dimensional, two band model with short range electron-electronrepulsions (onsite $U$ and nearest-neighbour $V$ terms) and electron-phononcoupling. We show that there is a region of $U$,$V$ and band filling in whichsinglet superconductivity fluctuations are dominant. This region is absentwithout electron-phonon interactions and includes large values of $U$,$V$.
