With a motor in rotation, 0 is set as each of a d-axis current command and a q-axis current command, and offset learning is carried out. Then, in carrying out offset learning, a transmission is controlled such that a shift stage of the transmission falls within a low vehicle speed-side predetermined shift stage range. Thus, the rotational speed of the motor can be more reliably made high to a certain extent, and offset learning can be carried out. As a result, the accuracy of offset learning can be restrained from decreasing.
