Problems solved by technology

Also, many people complain of discomfort due to air flow over their face, but can't decide if it's best to adjust the airflow in the first place or the fan selection and characterization to reduce air flow
Nor does it take into account the state of the user at the current moment, such as his clothes or energetic activity (e.g. is he back from a jog?)

Embodiment Construction

[0122] figure 1 A thermal management system 1 for a passenger compartment of a motor vehicle is shown, the system comprising a control unit 2 arranged to:

[0123] - obtaining first data (Clo) representative of the dress level of the passengers in the passenger compartment,

[0124] - Acquisition of second data (MET) representing the metabolic activity of the passenger,

[0125] - obtaining third data representative of the thermal environment of the passengers in the passenger compartment,

[0126] - Based on the three data thus obtained, determine the value of the thermal comfort index (PMV) related to the passengers in the passenger compartment.

[0127] The system includes a plurality of sensors arranged to measure a plurality of parameters for determining the first, second and third data.

[0128] These sensors include:

[0129] - DMS camera 3 to observe the passengers in the passenger compartment,

[0130] - an infrared dome 4, formed by a wide-angle infrared camera ...

Abstract

The invention relates to a thermal management system for a motor vehicle interior, said system comprising an air-conditioning device that includes at least one outlet for thermally treated air, the air-conditioning device including in particular an HVAC unit, and the system further comprising a control unit designed to: acquire first data representing the amount of clothing worn by a passenger inthe vehicle interior (Clo) and / or second data representing the passenger's metabolic activity (MET); acquire a parameter that is related to a state of thermal comfort and can have at least two extremevalues, one of the values being associated with a calm state and the other value being associated with a dynamic state; manage the air-conditioning device to supply treated air at a flow rate that isdependent on the aforementioned parameter, said flow rate being lower when the parameter is associated with a calm state and higher when the parameter is associated with a dynamic state while the amount of clothing and / or the metabolic activity is the same in either case.

Description

technical field [0001] The invention relates to a motor vehicle thermal management system. The invention also relates to a method of thermal management implemented by such a thermal management system. Background technique [0002] In motor vehicles, it is known to manage the flow rate, temperature and distribution of the air blown by the various fans according to the outside temperature and insolation conditions. In some vehicles, this can be combined with activation of a heated steering wheel and / or heated or cooled seats, and sometimes through contact with heated surfaces such as elbow rests. [0003] In addition to using infrared sensors to detect the surface temperature of the passenger's clothing to better account for some examples of initial conditions and heat balances generated by radiative and convective exchanges during the temporary welcome phase (whether entering from a cold or hot environment), the detection and / or Or consider that the thermal state of the pas...
