Thermal request mediating device for controlling allowable amounts of discharged heat for thermal circuits

Abstract

A thermal request mediating device () that is mounted in a vehicle including a first thermal circuit (LT) and a second thermal circuit (RE) configured to exchange heat with the first thermal circuit, the thermal request mediating device includes: a discharged heat amount acquiring unit configured to requested amounts of discharged heat of the first and second thermal circuits; and a mediation unit configured to determine amounts of discharged heat allowable for the first thermal circuit and the second thermal circuit, and increase the amount of discharged heat allowable for the first thermal circuit and decrease the amount of discharged heat allowable for the second thermal circuit as the first requested amount of discharged heat increases when the sum of the amounts of discharged heat of the first and second thermal circuits exceeds the maximum amount of dischargeable heat.
