  • Patent number: 9970329
    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 device 1A includes a Rankine cycle device 2A, a power transmission mechanism 3A, and a control unit 4. The power transmission mechanism 3A has a clutch 31 and is capable of transmitting power between an engine 10 and the Rankine cycle device 2A when the clutch 31 is engaged. The control unit 4A controls the engagement and disengagement of the clutch 31 based on a first correlation value correlated with consumed power when the Rankine cycle device 2A is started, and a second correlation value correlated with consumed power of the Rankine cycle device 2A when the output of the Rankine cycle device 2A is negative during the operation of the Rankine cycle device 2A after the start-up.
