For 51,385 stars in the eld of view of the Kepler space telescope, we provide a homogeneous determination of the atmospheric parameters (Te , log g, and [Fe=H]) and the radial velocities (RV ). The projected rotational velocities (v sin i) have been measured for the rapid rotators (v sin i > 120 km/s). For the cool stars (Te < 6000 K), the H and Ca ii infrared triplet (IRT)  fluxes have been computed. Those parameters have been obtained from the spectroscopic observations acquired with the LAMOST instrument in the observing seasons 2011-2014. Our analysis was carried out with a purposely developed version of the code ROTFIT. The typical accuracy of our determinations is 10{15 km/s in RV , 3.5% in Te , 0.3 dex in log g, and 0.2 dex in [Fe=H]. All the spectra have been searched for peculiarities.
