Controller of vehicle

A controller installed on a vehicle including an engine, a first rotary electric machine for power generation which generates electric power using driving force from the engine, a second rotary electric machine for propulsion which delivers driving force for driving drive wheels, a power storage device, a first inverter for power generation which performs conversion of electric power between the first rotary electric machine and the power storage device, a second inverter for propulsion which performs conversion of electric power between the second rotary electric machine and the power storage device, and a circuit that has at least a capacitor and electrically connects the first inverter and the second inverter to the power storage device, the controller being adapted to perform drive control on the first rotary electric machine and the second rotary electric machine, the controller comprising

• a drive control changing unit configured to, when a total value of a power-generation-side ripple current and a drive-side ripple current is equal to or larger than a preset threshold value, change drive control of at least one of the first rotary electric machine and the second rotary electric machine such that the total value is reduced, the power-generation-side ripple current being generated according to an operating state of the first rotary electric machine and the drive-side ripple current being generated according to the operating state of the second rotary electric machine,
