Abstract: A method for regulating comfort in a passenger compartment of a vehicle, the passenger compartment including a seat, a radiant panel, and a heating device for the seat; the method being implemented by a controller having a memory containing a pre-established map. The method includes the following steps: acquiring a data item that is characteristic of the state of the passenger compartment, the characteristic data item including the temperature of the passenger compartment; determining, from the map, an optimal comfort level as a function of the characteristic data item; reading, in the map, regulation values associated with the optimal comfort level, the regulation values including values representative of the operating power of the radiant panel and of the heating device for the seat; and transmitting the read regulation values to the radiant panel and to the heating device.

Abstract: A method, which seeks to determine the air change rate of a space, includes, over at least two successive time periods corresponding to distinct given-gas flow rates applied in the space, carrying out a campaign of measurements to determine the concentration of the gas inside the space at closely-spaced time intervals, and the concentration of the gas outside the space is determined at closely-spaced time intervals. The value of the air change rate of the space is determined by causing the convergence of a diffusive model expressing the temporal variation of the concentration of the gas inside the space as a function of the concentration of the gas outside the space and of physical parameters of the space from which parameters the air change rate of the space can be calculated, and the measured change in the concentration of the gas inside the space as a function of time.
