Abstract:
An in-vehicle temperature estimation device (30) is applied to an in-vehicle heating object (11) heated by energization. The in-vehicle temperature estimation device (30) has a power detection unit (20A) that detects supplied power (P) supplied to the heating object (11), a calculation unit (20C) that performs a calculation for estimating the temperature of a first object position (P2) in the heating object (11), and a temperature-specifying unit (20B) that specifies the temperature of the outside air outside of the heating object (11). The calculation unit (20C) performs the calculation for estimating the temperature of the first object position (P2) on the basis of the supplied power (P) detected by the power detection unit (20A) and the temperature of the outside air specified by the temperature-specifying unit (20B).
