Description

Technical Field

[0001] This invention relates to the field of automotive air conditioning control technology, specifically an intelligent wind zone adaptive control method and system. Background Technology

[0002] Traditional automotive air conditioning airflow control systems suffer from significant deficiencies in control precision and adaptive capabilities when facing complex driving conditions and personalized passenger needs. Existing technologies often employ control logic with fixed vent openings and preset air pressure, failing to dynamically adjust the airflow strategy based on vehicle driving conditions and cabin pressure distribution. For example, when a vehicle is traveling at high speed, the dynamic pressure of external airflow significantly affects the air conditioning inlets. Traditional systems do not consider the cumulative effect of this dynamic pressure on the airflow pressure, leading to a large deviation between the actual and target airflow. This is especially problematic in multi-zone independent control scenarios (such as front left and right zones, and rear zones), where pressure coupling between vents can easily cause uneven airflow distribution, resulting in some zones experiencing either "excessive airflow" or "insufficient airflow."

[0003] Furthermore, traditional control methods lack a linkage model between wind pressure, vehicle speed, circulation mode, and vent opening, making it difficult to adapt to complex environmental changes. For example, when the vehicle switches to external circulation mode, traditional systems only control airflow through a fixed threshold, without dynamically adjusting vent opening based on wind pressure. During uphill or acceleration conditions, heat radiation from the engine compartment causes fluctuations in intake air temperature, and traditional systems do not correct for wind pressure in heating and cooling modes, resulting in poor temperature stability at the air outlet and reduced passenger comfort.

[0004] Meanwhile, traditional systems do not have a matching algorithm between air vent opening and air pressure. When multiple zone air vents are opened at the same time, the air pressure is easily unbalanced due to changes in total air resistance, resulting in abnormal phenomena such as airflow whistling. There is an urgent need for an intelligent wind zone adaptive method that integrates dynamic pressure analysis and multi-parameter collaborative control to improve the control accuracy, comfort and energy efficiency of automotive air conditioning systems.

[0005] Therefore, an intelligent wind zone adaptive control method and system are provided. Summary of the Invention
