Zusammenfassung:	PROBLEM TO BE SOLVED: To propose an electric vehicle controller for informing a pedestrian of an approaching vehicle.SOLUTION: A plurality of power converters (30, 40, 50) implement a desired power conversion operation by implementing drive control of a switching element based on individual carrier frequencies. If a vehicle speed is less than a predetermined value, the electric vehicle controller (60) synchronizes the carrier frequencies of the plurality of the power converters (30, 40, 50), and increases a sound pressure of an operation sound.
