Title:
EXHAUST HEAT RECOVERY CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2015145663
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To achieve both exhaust heat recovery and the suppression of performance degradation due to freezing of condensate water.SOLUTION: An exhaust heat recovery control device comprises: a recovery-amount regulation unit 16 regulating a recovery amount of heat of exhaust gas by which an exhaust heat recovery unit 12 recovers the heat of the exhaust gas; and a controller 14 controlling the recovery-amount regulation unit 16 so as to prevent or suppress freezing of an interior of an exhaust pipe on the basis of a travel history if it is predicted that the interior of the exhaust pipe is frozen. For example, if it is predicted that the interior of the exhaust pipe is frozen and previous travel time is equal to or shorter than a preset reference, the exhaust-heat recovery amount is reduced.
