Embodiment Construction

[0033] The present invention will be further described below in conjunction with accompanying drawing.

[0034] The method for actively purifying the air in the vehicle after the vehicle is turned off and parked according to the present invention, the connection structure of the hardware involved is as follows: figure 1 As shown, it includes an air conditioner controller 1, a blower speed control module 2, a blower 3, a blower relay 4, a blower fuse 5, and a storage battery 6 (for power supply). Compared with the traditional blower control method, the main change point is that the control coil of the blower relay 4 is directly connected to the air conditioner controller 1 , and the control strategy involved in this method is mainly implemented by the air conditioner controller 1 .

[0035] In this embodiment, the air conditioner controller is configured such that after the vehicle is turned off and parked, the air conditioner controller can control the HVAC actuators, the actu...

Abstract

The invention discloses a method for active purification of air in vehicle after shut-down and parking. The air-conditioning controller is configured as: after the vehicle shuts down and parks, the ignition voltage IGN is OFF and an air-conditioner controller can control an actuator of a HVAC, the actuator includes a blower, an inner and outer circulation air door, a mode wind door and a temperature wind door; the method comprises the following steps of: starting the timer to timing in response to the shutdown of the vehicle and the complete closure of all the doors; and performing the activeventilation action when the timing time reaches the preset time and the current accumulator voltage is greater than the preset voltage value. The method can effectively reduce the car odor and harmfulVOCs in the long-term parking vehicles after the shutdown, and greatly increase the user's satisfaction with the air in the vehicle with very low cost.

Description

technical field [0001] The invention belongs to the technical field of automotive air conditioners and odor purification in vehicles, and in particular relates to a method for actively purifying the air in vehicles after the vehicle is turned off and parked. Background technique [0002] According to the previous online survey of Autohome, customers have higher and higher requirements for the air quality in the car. As high as 93.4% of the users are concerned about the air quality in the car, and only 21.1% of the users are concerned about the air quality in the car. satisfy. Through research, it is found that users' complaints about the smell in the car are mainly concentrated after the vehicle is closed for a long time and the smell in the car reaches a certain concentration. Experience shows that the longer the parking time, the more serious the odor in the passenger compartment of the vehicle, and research shows that the longer the parking time, the higher the ambient t...
