CONTROL APPARATUS, VEHICLE SYSTEM, AND CONTROL METHOD

A control apparatus includes: a data acquisition part that acquires correction data indicating a content regarding a correction process which corrects an error of an angle at which a rotation angle sensor that measures a rotation angle of a rotor included in an electric motor is attached; a determination part that determines, based on the correction data, whether or not the correction process has been performed; and a control method determination part that determines, in a case where it is determined that the correction process has not been performed, that an inverter which supplies an AC current to the electric motor is controlled under a pulse-width modulation control.
