Embodiment 1

[0084] Such as Figure 1-2 Shown, the present invention provides a kind of control method of automobile air conditioner, it comprises:

[0085] Pre-remote control, the pre-remote control includes pre-remote timing control: the pre-remote timing control includes turning on the air conditioner for pre-cooling or heating t0 minutes before the start of the car, where t0 is a constant.

[0086] The present invention proposes pre-remote control for new energy vehicle air conditioners, mainly including remote timing start-up control and remote intelligent temperature control, and at the same time taking into account the temperature control of the battery pack. Pre-remote control refers to when the passenger or driver has not boarded the car, the driver can remotely start the car at a fixed time through the air-conditioning controller on the car or the mobile phone APP (that is, the pre-remote remote timing control) or remotely set the temperature in the car that needs to be reached a...

Embodiment 2

[0112] Such as image 3 As shown, this embodiment is a further improvement made on the basis of Embodiment 1. Preferably, the pre-remote control also includes remote intelligent temperature control, and the remote intelligent temperature control includes:

[0113] Setting steps: set the temperature inside the car to reach Tset2 within the time t3;

[0114] Detection steps: detect the ambient temperature Tin in the vehicle;

[0115] Calculation steps: calculate the shortest time t4 for the temperature in the car to reach Tset2 (that is, the cooling time for the system to operate in the maximum capacity operation mode is t4);

[0116] Judging step: judging the size relationship between t3 and t4;

[0117] Execution steps: when t3≤t4, control the operation of the air conditioner with the maximum capacity output mode; when t3>t4, according to the implanted algorithm, select the cooling / heating mode with the best energy efficiency to control the system.

[0118] Define the cooli...

Embodiment 3

[0146] This embodiment is a further improvement made on the basis of Embodiment 1 and / or 2. When the new energy vehicle has a battery pack thermal management system, the pre-remote control also includes battery temperature pre-control, and the battery temperature Pre-control includes:

[0147] Detection steps: means to automatically detect whether the temperature of the car battery pack is within the optimum power supply temperature range;

[0148] Execution steps: when the temperature of the battery pack is within the optimum power supply temperature range, no pre-control is performed on the battery pack; when the temperature of the battery pack is not within the optimum power supply temperature range, pre-temperature control is performed on the battery pack;

[0149] Wherein, the optimum power supply temperature range refers to that in this temperature range, the power supply efficiency of the battery pack is the highest.

[0150] When the new energy vehicle is equipped wit...

Abstract

The invention provides a control method for an automobile air conditioner. The control method comprises pre-remote control. The pre-remote control comprises pre-remote timing control. The pre-remote timing control is that an air conditioner is started t0 minutes before the start of an automobile to pre-cool or pre-heat, wherein t0 is a constant. Compared with an automobile air conditioner in the prior art, through setting the pre-remote control step, the air conditioner can pre-cool or pre-heat before the start of the automobile, so the temperature of the air in the automobile can be controlled in advance; a comfortable temperature environment can be achieved when a user gets in the automobile and a comfortable environment is provided for the owner and passengers; a new energy vehicle airconditioner can be remotely-controlled and pre-controlled; and a preset comfortable temperature state can be achieved when persons get in the automobile.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to a method for controlling an automobile air conditioner. Background technique [0002] There are two deficiencies in the start-up control of the automotive air conditioner of traditional fuel vehicles. One is that it needs to be manually controlled in the car, and the other is that the engine needs to be powered on to turn on the air conditioner. It is impossible to remotely turn on the air conditioner, that is, to pre-cool and pre-heat the air in the car, so the user's comfort is not high. [0003] For new energy vehicles, the air-conditioning system and the engine system are independent of each other. They are powered by batteries. The air-conditioning compressor does not need to be turned on by the car engine. The inner space is pre-cooled and pre-heated, but no application has been seen. [0004] In addition, the energy efficiency of the traditional air ...
