Provided is a vehicle interior-compartment air-quality regulation system, comprising a negative-ion generator (10), an air-quality monitoring device (30), and a master controller (20) the air-quality monitoring device (30) is arranged in the vehicle interior compartment and electrically connected to the master controller (20), and is used for monitoring a parameter of the air quality inside the vehicle and obtaining monitoring data, and sending the monitoring data to the master controller (20) the master controller (20) receives the monitoring data and according to the monitoring data, generates a control instruction and sends same to the negative-ion generator (10) the negative-ion generator (10) is arranged in the vehicle interior compartment and is electrically connected to the master controller (20), and is used for increasing, according to the received control instruction, the concentration of negative ions in the vehicle interior compartment. The present invention is such that when the concentration of negative ions in the vehicle interior compartment is low, the concentration of negative ions in the vehicle interior compartment is increased by means of the negative-ion generator (10), causing the environment for driving and riding in the vehicle interior compartment to be comfortable.Linvention concerne un système de régulation de la qualité de lair pour habitacles de véhicule, comprenant un générateur dions négatifs (10), un dispositif de surveillance de la qualité de lair (30) et un dispositif de commande principal (20).
