Embodiment 1

[0032] The embodiment of the present invention provides a method for controlling the blower of an automobile air conditioner, which can adopt figure 1 The circuit shown is implemented, see figure 2 , the method includes:

[0033] Step 201, when the blower is started when the air volume gear is at the first gear, the terminal voltage of the blower is adjusted to the lowest start-up voltage.

[0034] This step 201 can be realized by monitoring the air volume gear position signal of the blower by the automatic air-conditioning control module.

[0035] Step 202 , after controlling the blower to run at the lowest starting voltage for a set period of time, adjust the terminal voltage of the blower from the lowest starting voltage to the lowest operating voltage, so that the blower operates at the lowest operating voltage.

[0036] It is easy to know that the minimum operating voltage is lower than the minimum starting voltage.

[0037] It can be understood that when the blower i...

Embodiment 2

[0040] An embodiment of the present invention provides a method for controlling an automobile air-conditioning blower, see image 3 , the method includes:

[0041] Step 301 , when the blower is started when the air volume gear is at the first gear, adjust the terminal voltage of the blower to the lowest start-up voltage.

[0042] This minimum starting voltage is the lowest voltage required for the blower to start. The minimum start-up voltage is provided by the supplier of the automotive air-conditioning blower, which is an inherent characteristic of the blower, and a certain margin will be reserved during design to ensure the normal operation of the blower.

[0043] In this embodiment, the minimum start-up voltage is 3.84V-4.24V, and the preferred minimum start-up voltage is 3.84V.

[0044] This step 301 can be realized by monitoring the air volume gear position signal of the blower by the automatic air conditioner control module.

[0045] Step 302, controlling the blower ...

Abstract

The invention discloses an automobile air conditioner blower control method and belongs to the technical field of automobile control. The method includes the steps: when a blower is started under a first level of air volume, end voltage of the blower is adjusted to lowest start voltage; the blower is controlled to operate in a set period under the lowest start voltage, the end voltage of the blower is adjusted from the lowest start voltage to lowest operating voltage, the blower thus operates under the lowest operating voltage which is smaller than the lowest start voltage. The lowest voltage which can guarantee normal operation of the blower is adopted, the end voltage of the blower is low, the volume of air generated during operating is low, the nose of the air conditioner blower is low, and automobile NVH performance is optimized accordingly.

Description

technical field [0001] The invention relates to the technical field of automobile control, in particular to a method for controlling an automobile air-conditioning blower. Background technique [0002] With the rapid development of the automobile industry, the application of various new technologies has gradually improved the overall performance of the automobile. Customers have more stringent requirements on the performance of the car in all aspects, that is, customers no longer regard the car as just a means of transportation. Vibration roughness) performance, the requirements are getting higher and higher. [0003] The noise of automobile air conditioner blower accounts for a large proportion in the NVH of the whole vehicle, especially when the car is driving on the expressway for a long time, because the environment outside the car is relatively quiet, when the noise of the air conditioner blower is loud, the people in the car will obviously feel uncomfortable. In ord...
