Embodiment Construction

[0047] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0048] The automobile air-conditioning compressor rotational speed control method of the present invention, as figure 1 shown, including:

[0049] Step S101: Obtain the blower voltage of the blower at the current gear, and determine the blower noise generated in the vehicle when the blower is at the current gear according to the blower voltage;

[0050] Step S102: According to the blower noise, calculate the maximum compressor noise in the car that the compressor is allowed to generate, and determine the maximum allowable speed of the compressor under the current working condition according to the maximum compressor noise;

[0051] Step S103: Control the rotation speed of the compressor to not exceed the maximum allowable rotation speed of the compressor.

[0052] Specifically, the automobile blower is used to control the air output...

Abstract

The invention discloses a method for controlling the rotational speed of an automobile air conditioner compressor, comprising: obtaining the blower voltage of the blower at the current gear, and determining the blower noise generated in the car when the blower is at the current gear according to the blower voltage; according to the blower Noise, calculate the maximum compressor noise in the car that is allowed to be produced by the compressor, and determine the maximum allowable speed of the compressor under the current working condition according to the maximum compressor noise; control the speed of the compressor to not exceed the maximum allowable speed of the compressor . According to the blower voltage at the current gear, the present invention determines the blower noise and calculates the maximum compressor noise in the car that the compressor is allowed to produce, determines the maximum allowable rotation speed of the compressor under the current working condition, and keeps the rotation speed of the compressor not exceeding the compression speed. The maximum allowable rotation speed of the compressor can be controlled, so that the noise level of the compressor can always be kept at the same level as the noise level of the blower, so that the noise of the compressor is not easy to be perceived by the driver and passengers.

Description

technical field [0001] The invention relates to the technical field related to automobiles, in particular to a method for controlling the rotational speed of an automobile air-conditioning compressor and electronic equipment. Background technique [0002] With the development of the automobile industry, the market share of electric vehicles and hybrid energy vehicles is increasing. Compared with fuel vehicles, electric vehicles have no background noise from the engine, which improves the driving experience for drivers and passengers. However, at the same time, due to the small background noise, the noise generated by the operation of the air conditioner compressor is also easier to perceive, especially when the car is idling, which affects the driving experience of the driver and passengers to a certain extent. [0003] Therefore, it is necessary to provide a method for controlling the rotational speed of the air conditioner compressor to solve the problem that the noise of...
