Abstract
In an exhaust heat recovery device provided with a Rankine cycle device, a clutch for transmitting and interrupting power between an engine and the Rankine cycle device is released appropriately to prevent the Rankine cycle from becoming a load on the engine. An exhaust heat recovery deviceA includes a Rankine cycle deviceA, a power transmission mechanismA, and a control unit. The power transmission mechanismA has a clutchand is capable of transmitting power between an engineand the Rankine cycle deviceA when the clutchis engaged. The control unitA controls the engagement and disengagement of the clutchbased on a first correlation value correlated with consumed power when the Rankine cycle deviceA is started, and a second correlation value correlated with consumed power of the Rankine cycle deviceA when the output of the Rankine cycle deviceA is negative during the operation of the Rankine cycle deviceA after the start-up.
