What is AQS in cars?
2 Answers
Automotive AQS stands for Air Quality System. Below are specific details about the response sensitivity of AQS: 1. Vehicle exhaust: AQS is highly sensitive to vehicle exhaust. In urban traffic jams, when the vehicle ahead suddenly emits a large amount of exhaust, the intelligent air conditioning system can detect it within seconds and immediately switch to the internal circulation mode, keeping the cabin air fresh. 2. Road dust: AQS has a moderate response to road dust. When driving on a slightly dusty road, AQS does not switch immediately. It only quickly switches to the internal circulation mode when the road dust becomes more severe.
I've been driving for over a decade and know a thing or two about AQS. The car's AQS is essentially an air quality system that automatically detects whether the outside air is clean through sensors at the front of the vehicle. For example, when it detects excessive levels of PM2.5, exhaust fumes, or odors, it immediately switches the air conditioning to recirculation mode, instantly freshening the air inside the car. On long drives during hazy days, it’s incredibly useful—it’s like having an invisible air purifier, making the cabin feel comfortable. I’ve also noticed that newer SUVs and electric vehicles come standard with this feature, designed with multi-layer filtration systems for both health protection and peace of mind. When driving on highways, don’t forget to occasionally check if the filter is clogged—maintenance is a breeze.
