Problems solved by technology

[0008] As mentioned earlier, traditional control panels used in electric vehicles can cause trouble
In fact, if the user controls a higher heating temperature followed by a strong wind, due to the limitation of the available electric power for the heating element, cold air will enter the interior of the cabin, which will cause confusion on the part of the user
However, traditional control panels used in the case of internal combustion engines are not suitable to be used in electric vehicles

Embodiment Construction

[0028] First refer to figure 1 , which shows a control panel 10 according to the prior art, generally used in motor vehicles with heat engines and comprising a temperature rotary adjustment mechanism 12, a fan power rotary adjustment mechanism 14 and an air distribution rotary mechanism 16 capable of adjusting Control valves (not shown) in access to designated areas A1 , B1 , C1 and D1 of the cars. A1 may for example correspond to the air input at the bottom position of the compartment to circulate the air at the position of the person's legs, A3 corresponds to the high part of the compartment where the air is brought, and A3 corresponds to the low and high parts where the air is brought The middle section between, to circulate air around a person's upper body or face, and the A4 corresponds to the low and middle sections that bring the air synchronously. Dispensing mechanisms of this type are known to those skilled in the art.

[0029] The fan adjustment mechanism 14 may ha...

Abstract

The invention relates to a heating control device in a motor vehicle, more particularly in an electric vehicle, said device comprising an electric heating means (30) for an air flow and a fan means (32) for this hot air inside the vehicle compartment. , the temperature regulating mechanism (26) is intended to be installed inside the cabin and is actuable between a plurality of states (A2, B2, C2, D2), each state corresponding to a desired air temperature inside the cabin. According to the invention, the device includes a control member (28), the input of which is connected to the temperature regulating mechanism (26) and the output is connected to the heating member (30) and the fan member (32), the control member (28) being configured The heating member (30) and the fan member (32) are synchronously controlled according to the temperature regulating mechanism (26).

Description

[0001] field of invention [0002] The present invention relates to heating controls in motor vehicles, more particularly electric vehicles. Background technique [0003] In heat engine motor vehicles, the heating of the cabin is usually carried out by air / water heat exchange, the water circuit is heated by the dissipation of heat from the running engine, and the air from outside the cabin is heated by contact with the water circuit. When the engine is heated, the output of this heating device is about 10 to 12 kilowatts, which is more than enough for the needs of heating the cabin. [0004] The vehicle also includes fan means for circulating air within the vehicle cabin. The distribution of air inside the vehicle is effected by means of control valves placed in ducts that bring air to designated areas of the cabin, such as the footwells and windshield, for defrosting or defogging. [0005] The cabin of a motor vehicle with an internal combustion engine typically includes a ...
