FIELD: engines.
SUBSTANCE: invention can be used in internal combustion engines used on vehicles. Device (10) for controlling exhaust heat recovery includes a unit (16) for controlling recovered heat, configured to control amount of heat recovered from exhaust gas, exhaust gas heat recuperator (12), and control unit (14). Control unit (14) is configured to control unit (16) for controlling recoverable heat so as to prevent or eliminate freezing in exhaust pipe based on vehicle path data that sets a heat recovery control device of exhaust gases in prediction of freezing in exhaust pipe.
EFFECT: technical result consists in prevention of freezing of water condensate at running vehicle and preventing reduction of engine power output and abnormalities of internal noise due to exhaust sound.
