Method to adjust the temperature of an element of a motor vehicle to be interfaced with a passenger of the motor vehicle and motor vehicle comprising said element

A motor vehicle (1) comprising:

• a body (2) defining a passenger compartment (3);
• an adjustment system comprising a conditioning system (7) for a first temperature (Tcabina) inside said passenger compartment (3), the conditioning system (7) comprising a plurality of air vents (9);
• a control unit (20) designed to control said adjustment system for the first temperature (Tcabina) inside said passenger compartment (3) and by means of which a second temperature (Trichiesta) requested inside said passenger compartment (3) can be set;
• a first sensor (10) configured to detect a third external temperature (Tout) on the outside of a passenger compartment (3) of said motor vehicle (1);
• a second sensor (14) configured to detect a current value of said first temperature (Tcabina) on the inside of said passenger compartment (3) of said motor vehicle (1);
• at least one element to be interfaced with a passenger of said motor vehicle (1), the at least one element comprising at least one of a seat (15a, 15b) and a steering wheel (15c);
• and
• adjustment means (23, 24) for a fourth temperature (Tutenza) of said element (15a, 15b, 15c) to be interfaced, which can be operated in order to exchange a heat power with said element (15a, 15b, 15c) and adjust said fourth temperature (Tutenza), the adjustment means (23, 24) comprising a plurality of heating elements (30) comprising electrical resistances (40) and a plurality of cooling elements (31) comprising fans (41);
• a third sensor (50, 51) configured to detect a current value of the fourth temperature (Tutenza) of said element (15a, 15b, 15c);
• and
• the control unit (20) programmed to:
• process a fifth temperature (Tprev) based on said fourth, first and second temperature (Tutenza;
• Tcabina;
• Trichiesta);
• and
• generate, based on said fifth temperature (Tprev), a command for said adjustment means (23, 24) so as to adjust said fourth temperature (Tutenza);
• said control unit (20) being programmed to process said fifth temperature (Tprev) also based on said third external temperature (Tout);
• characterized in that said control unit (20) is programmed to process said fifth temperature (Tprev) based on the following formula:
• Tprev

• ,
• wherein:
• TRIF is a sixth temperature that can selectively be set by said passenger;
• α and β are coefficients that depend on said third temperature (Tout) and are independent of said fourth, first and second temperature (Tutenza;
• Tcabina;
• Trichiesta);
• and
• γ is a constant coefficient.
