Embodiment 1

[0041] A vehicle air conditioner control method, used to control the air quality in the vehicle air conditioner from the aspects of energy consumption, safety and comfort, such as figure 1 with figure 2 shown, including the following steps:

[0042] A. PM2.5 calculation steps, according to the PM2.5 level in the car, the PM2.5 level outside the car and the speed of the car, the air pollution index positively correlated with PM2.5 is calculated, and the air pollution index is positively correlated with the degree of air pollution. Wherein, in the present invention, the air pollution index only considers the PM2.5 index. In order to further specify the air pollution index, it includes the PM2.5 index outside the car and the PM2.5 index inside the car. Specifically, this step is as follows image 3 As shown, including the following sub-steps:

[0043] A1. Collect the PM2.5 index outside the car, the PM2.5 index inside the car and the current vehicle speed at the current momen...

Embodiment 2

[0051] The difference between this embodiment and Embodiment 1 is that this embodiment specifically provides various internal and external circulation control schemes.

[0052] Option One:

[0053] Such as Figure 7shown. In step B, after the air humidity reaches the humidity threshold, when the temperature outside the vehicle is lower than the first preset temperature, an inner circulation rejection command is issued to start the outer circulation; when the outside temperature is greater than the second preset temperature, an inner circulation permission is issued Instruction; the first preset temperature is lower than the second preset temperature.

[0054] Option II:

[0055] Such as Figure 8 shown. In step B, when the temperature outside the vehicle is lower than the third preset temperature, an inner circulation rejection command is issued to start the outer circulation; when the outside temperature of the vehicle is greater than the fourth preset temperature, an in...

Embodiment 3

[0062] This embodiment provides a vehicle-mounted air conditioner controller on the basis of Embodiment 1, such as Figure 10 shown. Including: PM2.5 calculation module, negative ion control module, fan control module and internal and external circulation control module.

[0063] Among them, the PM2.5 calculation module is connected with the negative ion control module, the fan control module and the internal and external circulation control module, and is used to calculate the air pollution index according to the PM2.5 level inside the vehicle, the PM2.5 level outside the vehicle and the vehicle speed. The negative ion control module is used for generating negative ions according to the air pollution index. The fan control module is used to adjust the fan speed according to the air quality, usually when the air pollution index is higher. The internal and external circulation control module is used to control the circulation mode of the air conditioner according to at least ...

Abstract

The invention relates to a vehicle-mounted air conditioner control method. The vehicle-mounted air conditioner control method comprises the following steps of step A, calculating PM2.5; step B, internal circulation and external circulation control, specifically, according to one or more parameters of the air pollution index, the air humidity, the environmental temperature and the air output temperature, sending an internal circulation refusing command or an internal circulation allowing command; and step C, controlling air output capacity and negative ions. In the step B, when the parameters are adopted, the parameters have a specific priority order, and the sent command adopts the high-priority parameter. The invention also provides a vehicle-mounted air conditioner control system. The vehicle-mounted air conditioner control system comprises a PM2.5 calculating module, a negative ion control module, a fan control module and an internal circulation and external circulation control module. The vehicle-mounted air conditioner controller and the control method thereof disclosed by the invention have the beneficial effects that the novel internal circulation and external circulation control module is designed; on the premise that the conventional comfortableness is not changed, the purpose of energy-saving purification control of a purification system is realized; and besides, automatic internal circulation and external circulation switching can be well realized without the need for manual operation.

Description

technical field [0001] The invention relates to the field of vehicle air conditioner control, in particular to a vehicle air conditioner controller and a control method. Background technique [0002] With the accelerated development of automotive electronics technology, better requirements are put forward for the comfort, safety, and environmental protection of automobiles. For the traditional automotive air conditioning system, on the one hand, the smoke of the passengers in the car or the dust outside the car enters the car, which will endanger human health; hazard to human health. [0003] In the existing technology, in order to purify the environment inside the car, the purification system usually only detects the PM2.5 level inside the car when removing PM2.5, and does not combine the air quality outside the car, so it will lead to long-term circulation. Yes, inside the car A decrease in the oxygen content of the air occurs. [0004] In addition, whether the purifica...
