CONTROLLER OF VEHICLE

A controller is installed in a vehicle. The vehicle includes an engine (2), rotary electric machine (MG1) for power generation, rotary electric machine (MG2) for propulsion, power storage device (6), inverter (5a) for power generation, and inverter (5b) for propulsion. The controller includes a drive control changing unit that changes drive control of at least one of the rotary electric machine (MG1) for power generation and the rotary electric machine (MG2) for propulsion, for reduction of a total value of a power-generation-side ripple current generated according to an operating state of the rotary electric machine (MG1) for power generation, and a drive-side ripple current generated according to the operating state of the rotary electric machine (MG2) for propulsion, when the total value is equal to or larger than a preset threshold value.
