Problems solved by technology

[0008] In order to equip each mechanical or electromechanical actuator of the air conditioner with its own sound-absorbing device, both in manufacture and assembly, it will result in higher cost and greater work intensity.
Furthermore, such noise reduction measures are necessarily accompanied by a reduction in the available installation space in the vehicle interior

Embodiment Construction

[0050] exist figure 1 The heating, ventilation or air-conditioning equipment shown schematically in FIG. 1 , referred to as an HVAC system 12 , is controlled and regulated by a control unit 14 . The HVAC system 12 is here ventilatedly connected to the vehicle passenger compartment. in accordance with figure 1 The control unit 14 shown as a separate unit next to the HVAC system 12 in the block diagram of FIG.

[0051] The control unit 14 is coupled, for example, to two operating elements 24 , 26 , wherein the operating element 24 is designed, for example, as a blower switch or an air distribution (air diffuser) switch or a corresponding regulator or slide valve, while the operating element 26 can be designed as For temperature switch or temperature regulator.

[0052] Furthermore, the control unit 14 is coupled to a plurality of signal generators or sensors 16 , 18 , 20 , 22 . This coupling can be directly connected to the control unit 14, but can also be realized indirectl...

Abstract

The invention relates to a method for controlling automobile heating, ventilation and / or air-conditioning equipment (12) while reducing noise. When the deviation between an actual value and a given rated value reaches to a threshold value (T0), a control unit (14) generates a control signal which is used for adjusting the equipment (12) and reducing the deviation. The threshold value (To) changes based on the GP in the automobile cabin. The invention also relates to a computer program product implementing the method, and an air-conditioning equipment with a relative configuration as the automobile.

Description

technical field [0001] The invention relates to a method for controlling a heating, ventilation and / or air conditioning system of a motor vehicle, in particular for controlling a motor vehicle HVAC system. Furthermore, the invention comprises a heating, ventilation or air-conditioning installation suitable for carrying out the method and a computer program product for controlling the installation. Background technique [0002] Air conditioning and ventilation equipment as well as HVAC systems are increasingly part of the car's family of equipment. The control and operation of such an air-conditioning system can take place manually, for example by means of various adjustable blower stages, but also automatically, for example as a function of a setpoint internal temperature set by the user. [0003] Heating, ventilation and / or air-conditioning systems, so-called HVAC systems, are generally equipped with an electronic control unit, which depends, for example, on the status of ...
