An air-conditioning control system for a vehicle includes an acquisitor configured to acquire an exposure temperature of an exposed body surface of an occupant and a clothing surface temperature of the occupant, a non-exposure temperature estimator configured to estimate a non-exposure temperature of a non-exposed body surface of the occupant on the basis of the exposure temperature and a clothing amount, a clothing amount estimator configured to estimate the clothing amount on the basis of the non-exposure temperature and the clothing surface temperature, and a control unit configured to control an air conditioner of a vehicle into which the occupant gets on the basis of an estimation result of the clothing amount estimator.

In order to perform overheating protection of a controller for water-heating heatersA andB for in-vehicle heating, an energization circuit for a heater(A,B) includes IGBTsandas switching devices that are disposed therein to be in series with the heater, and a first temperature sensor (first thermistor)which measures temperature of these IGBTs. A comparatoris provided to transmit a signal when the temperature of the IGBTsis equal to or greater than a predetermined temperature. Then, the IGBTscan be forcibly turned OFF via the IGBT driverin response to a signal from the comparatorwithout a microprocessorintervening therebetween.
