example 1

[0115] Example 1: The heating surface is made of steel.

[0116] The average heat absorption coefficient of steel ε steel =14,000J.m -2 .K -1 .s -1 / 2

[0117] The average heat absorption coefficient of the skin ε skin =400J.m -2 .K -1 .s -1 / 2 and its average temperature T skin = 37°C.

[0118] recognized by the system's sensors as the allowable maximum temperature T tolerated A passenger at =50° C. may touch the steel heating surface 5 of the heating panel 1 with his hand 6 . Through the control method ( figure 2 Boxes 8 and 9) Determine the dry bulb temperature T of the heating surface 5 dry It is related to the maximum permissible temperature by the following formula:

[0119]

[0120]

[0121]

[0122] T dry =50°C

[0123] In summary, the dry bulb temperature of the steel heating surface is about 50°C based on the heat absorption coefficient of the steel and the maximum temperature tolerated by the passenger.

example 2

[0124] Example 2: The heating surface is made of wood.

[0125] The average heat absorption coefficient of wood ε wood =500J.m -2 .K -1 .s -1 / 2

[0126] The average heat absorption coefficient of the skin is ε skin =400J.m -2 .K -1 .s -1 / 2 and its temperature is about T skin = 37°C.

[0127] recognized by the system's sensors as the allowable maximum temperature T tolerated A passenger at =50° C. may touch the wood heating surface 5 of the heating panel 1 with his hand 6 . Through the control method ( figure 2 Boxes 8 and 9) Determine the dry bulb temperature T of the heating surface 5 dry It is related to the maximum permissible temperature by the following formula:

[0128]

[0129]

[0130]

[0131] T dry =60°C

[0132] In summary, the dry bulb temperature of the wood heating surface is about 60°C based on the heat absorption coefficient of wood and the maximum temperature tolerated by the passenger.

[0133] According to a preferred embodiment, th...

Abstract

Method for controlling (7) the temperature of a heating surface (5) of a heating panel (1) intended to be installed inside a passenger compartment of a vehicle, for example a motor vehicle, said surface (5) being likely to be touched by a passenger in said passenger compartment, the method (7) comprising the following step: - controlling the temperature of said heating surface (5) according to atleast one datum which is representative of the profile of a passenger seated in the passenger compartment and / or at least one datum which is representative of the heating surface (5) of the heating panel (1). The invention also relates to a corresponding control device (15).

Description

technical field [0001] The field of the invention relates to devices for heating the passenger compartment of a vehicle, such as a motor vehicle, and more particularly to heating panels arranged inside such a passenger compartment. The invention relates to a method for controlling the temperature of a heating surface of a heating panel. The invention also relates to a device for controlling the temperature of the heating surface of such a heating panel. Background technique [0002] Most vehicles are provided with a system for heating the air to be sent into the passenger compartment. This heating system may be supplemented by one or more heating panels, ie surfaces that warm the passengers by infrared radiation and at the same time heat the air located inside the passenger compartment by convection. Current heating panels are shaped and / or sized to suit their location in the passenger compartment of the vehicle into which they are to be incorporated. By way of non-limiti...
