Abstract: The invention relates to a thermal management system for a passenger compartment of a motor vehicle, the system comprising a processing unit designed to determine an operative temperature setpoint TOC(t), also referred to as the operative comfort temperature, at a given time, and to use this operative temperature setpoint to manage the thermal comfort in the passenger compartment, said operative temperature setpoint TOC(t) at the given time (t) being a function of a reference operative temperature value (TOCRef), a variation DeltaCORP(t) of a physical build value CORP(t) of a person at the time (t) relative to a reference physical build value, a variation DeltaCLO(t) of a clothing value CLO(t) at the time (t) relative to a reference clothing value and a variation DeltaMET(t) of a value of the metabolic activity MET(t) at the time (t) relative to a value of the reference metabolic activity.

Abstract: The invention relates to a thermal management system for a motor-vehicle passenger compartment, this system comprising a processing unit arranged to: —acquire: —a datum (BA) representative of the respiratory amplitude of the passenger,—and/or a datum (BR) representative of the respiratory rhythm of the passenger, —a datum (HR) representative of the cardiac rhythm of the passenger, —optionally a datum on the age of the passenger, —optionally a time-related datum (T) that is representative of the moment during the day, the time of day for example, —determining a datum (MET) representative of the metabolic activity of the passage on the basis of the aforementioned data, —preferably then determining a value of a thermal-comfort index (PMV) associated with the passenger in the passenger compartment on the basis of the datum (MET) representative of the metabolic activity of the passenger.
