Embodiment 1

[0057] This embodiment provides a method for air conditioning control, see figure 1 , the method flow provided by this embodiment is specifically as follows:

[0058] 101: Determine whether the car meets the boundary conditions, and when the car meets the boundary conditions, obtain the throttle parameters of the accelerator pedal of the car;

[0059]102: Identify whether rapid acceleration power needs to be provided according to the throttle parameters, if it is necessary to provide rapid acceleration power, perform step 103, and if it does not need to provide rapid acceleration power, perform step 104;

[0060] 103: If it is necessary to provide rapid acceleration power and the air conditioner is on, control to turn off the air conditioner;

[0061] 104: If there is no need to provide power for rapid acceleration, and the air conditioner is controlled to be off, control to turn on the air conditioner.

[0062] Among them, the open state is that the air conditioner switch i...

Embodiment 2

[0069] Embodiment two

[0070] The embodiment of the present invention provides a method for controlling the air conditioner. For ease of understanding, combined with the content of the first embodiment above, the air conditioner switch is in the open position, and the current speed of the engine of the car is 2000 rpm when the air conditioner is controlled. Taking the opening degree change speed threshold as 45% / second as an example, the method provided in this embodiment is described in detail. see figure 2 , the method flow provided by this embodiment includes:

[0071] 201: Determine whether the car meets the boundary conditions;

[0072] For this step, because some factors may cause different power performances of the same car, this embodiment will determine whether the car meets the boundary conditions before performing the acquisition of the throttle parameters of the accelerator pedal of the car and identifying whether it is necessary to provide rapid acceleration p...

Embodiment 3

[0106] An embodiment of the present invention provides an air conditioner control device, see Figure 5 , the device consists of:

[0107] Judgment module 501, for judging whether the automobile satisfies the boundary conditions;

[0108] Obtaining module 502, used for obtaining the throttle parameter of the accelerator pedal of automobile when judging module 501 judges that automobile satisfies the boundary condition;

[0109] An identification module 503, configured to identify whether rapid acceleration power needs to be provided according to the throttle parameters acquired by the acquisition module 502;

[0110] The control module 504 is used to control to turn off the air conditioner when the identification module 503 recognizes that it is necessary to provide rapid acceleration power and the air conditioner is in the on state; Turn on the air conditioner.

[0111] Among them, the open state is that the air conditioner switch is in the open position and the air condit...

Abstract

The invention discloses an air conditioner control method and device and belongs to the technical field of automobile electronic control. The air conditioner control method comprises judging whether an automobile satisfies boundary conditions or not and obtaining throttle valve parameters of an acceleration pedal of the automobile when the automobile satisfies the boundary conditions; identifying whether emergency acceleration power supply is needed or not according to the throttle valve parameters; performing control to close the air conditioner if the emergency acceleration power supply is needed and the air conditioner is in an opening state; and performing control to open the air conditioner if the emergency acceleration power supply is not needed and the air conditioner is in a closed state. The air conditioner control method enables the accuracy of air conditioner control to be improved due to the fact that when an air conditioner switch is at an opening position, whether the automobile satisfies the boundary conditions or not is firstly judged, then whether the emergency acceleration power supply is needed or not according to the acceleration pedal throttle valve parameters is judged to confirm whether the air conditioner is controlled or not; the flexibility of air conditioner control is increased due to the fact that judging whether the automobile satisfies the boundary conditions or not is added before judging the acceleration pedal throttle valve parameters.

Description

technical field [0001] The invention relates to the technical field of automotive electronic control, in particular to an air-conditioning control method and device. Background technique [0002] Since the car air conditioner is one of the electrical loads that consume a lot of power, in hot summer, when the car air conditioner switch is on, if the driver needs acceleration power due to rapid acceleration, it is often because the car has turned on the air conditioner, making the acceleration weak. Therefore, how to control the air conditioner is the key to improve the acceleration performance of the vehicle when the air conditioner switch is in the on position and acceleration power is needed due to rapid acceleration. [0003] In the prior art, when controlling the air conditioner, the relationship between the opening of the throttle valve in the accelerator pedal and the threshold value is used to identify the driver's operation intention, so as to control whether to turn ...
