The controller controls an inverter that drives an in-vehicle three-phase motor. The controller includes a voltage application unit, a current obtaining unit, an addition unit, an addition conversion unit, and a derivation unit. The current obtaining unit obtains a positive current and a negative current flowing to each of the three phases. The addition unit adds the positive current and the negative current flowing to each phase. The addition conversion unit performs a three-phase to two-phase conversion on the three addition values. The derivation unit derives a magnetic pole position of the rotor, when the rotor is stopped, based on the conversion result of the addition conversion unit.
