  We study the possibility that inflation is driven by a scalar field together
with a vector field minimally coupled to gravity. By assuming an effective
potential that incorporates both fields into the action, we explore two
distinct scenarios: one where the fields interact and another where they do
not. In this context, we find different analytical solutions to the background
scalar-vector fields dynamics during the inflationary scenario considering the
slow-roll approximation. Besides, general conditions required for these models
of two fields to be realizable are determined and discussed. From the
cosmological perturbations, we consider a local field rotation, and then we
determine these perturbations (scalar and tensor) during inflation, and we also
utilize recent cosmological observations for constraining the parameter-space
in these scalar-vector inflationary models.
