Abstract
Official abstract text for this publication.
A coolant control device includes: first control means for, at warm-up of an internal combustion engine, circulating coolant in a first passage bypassing the engine and stopping coolant circulation in the second passage passing through the engine; second control means for, at engine warm-up and when the quantity of heat required by a heater core is smaller than or equal to a predetermined threshold, circulating coolant in the first passage while adjusting the flow rate of coolant circulating in the first passage and stopping coolant circulation in the second passage; and third control means for, at engine warm-up and when the required quantity of heat exceeds the predetermined threshold, circulating coolant in the first passage without decreasing the flow rate of coolant circulating in the first passage and circulating coolant in the second passage while adjusting the flow rate of coolant circulating in the second passage.
First claim
Opening claim text (preview).
The invention claimed is: 1. A coolant control device that controls a cooling device including a first passage for circulating coolant between an exhaust heat recovery device and a heater core while bypassing an internal combustion engine and a second passage for circulating the coolant between the internal combustion engine and the heater core, comprising: a first control unit that, during warm-up of the internal combustion engine, (i) circulates the coolant to the first passage…
