We present a temperature and doping dependent resonant inelastic X-rayscattering experiment at the V L$_{2,3}$ and O K edges inLa$_{1-x}$Sr$_x$VO$_3$ for $x=0$ and $x=0.1$. This material is a canonicalexample of a compound that exhibits a filling control metal-insulatortransition and undergoes orbital ordering and antiferromagnetic transitions atlow temperature. Temperature dependent measurements at the V L$_{3}$ edgereveal an intra-t$_{2g}$ excitation that blueshifts by 40 meV from roomtemperature to 30 K at a rate that differs between the para- andantiferromagnetic phases. The lineshape can be partially explained by a purelylocal model using crystal field theory calculations. At $x=0.1$ the doping isshown to affect the local electronic structure primarily on the O sites, whichis in disagreement with a simple Mott-Hubbard picture. We reveal the presenceof phonon overtone features at the O K edge, which evidences that the lowenergy part of the spectrum is dominated by phonon response.
