Abstract
A hybrid vehicle includes an engine, a first motor generator, a dynamic damper, and a power split mechanism. The dynamic damper includes an output-side rotating member, a spring element, and a second motor generator connected to the output-side rotating member so as to transmit the power. The dynamic damper is configured by connecting the output-side rotating member and the second motor generator via the spring element. The power split mechanism splits a power from the engine to the first motor generator and to the output-side rotating member. The control device includes an electronic control unit. The electronic control unit configured to change execution modes of rattling noise suppression control based on a spring characteristic of the dynamic damper. The rattling noise suppression control is a control to suppress rattling noise resulting from rotational fluctuations of the engine.
