[0047] Some embodiments of the present application are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present application and are not intended to limit the protection scope of the present application.

The term "at least one A or B" or "at least one of A and B" has a similar meaning to "A and / or B" and may include only A, only B or A and B. The singular terms "one" and "the" may also include plural forms.

[0049] As described in the background art, some vehicles have begun to use lithium batteries instead of traditional lead-acid batteries. Lithium batteries have a self-undervoltage protection function. When the battery voltage drops to a certain level, protection measures will be automatically taken to prevent over-discharge from damaging the battery.

[0050] During driving, if you use high-power electrical appliances such as the car air conditioner, headlights, inverter, wipers, etc. at the same time, the generator may not be able to generate enough electricity to meet the needs of these devices, and there is no excess electricity to charge the battery. This will cause the battery to be in a feeding state for a long time, which will have a negative impact on the life of the lithium battery.

[0051] In addition, during the use of the car air conditioner, there may be some problems with the air conditioning program, affecting the user experience.

[0052] In order to solve the above problems, the present application provides a control method, an electronic device and a storage medium for a vehicle air conditioner.

[0053] Among them, the indoor unit of the vehicle air conditioner can be connected to the vehicle CAN bus through the CAN communication interface, and connected to the vehicle terminal (Telematics BOX, T-BOX) through the CAN bus communication to achieve effective CAN communication with the T-BOX.

[0054] For details, see the attached Figure 1 , Figure 1 FIG. 1 is a flow chart of the main steps of a method for controlling a vehicle air conditioner according to an embodiment of the present application. Figure 1 As shown, the control method of the vehicle air conditioner in the embodiment of the present application mainly includes the following steps S101 to S103.

[0055] Step S101: Acquire the CAN signal sent by the vehicle terminal;

[0056] Among them, the CAN signal includes the engine speed signal and the battery capacity signal.

[0057] Step S102: Acquire engine status and / or battery capacity based on CAN signals;

[0058] Step S103: Control the use status of the vehicle air conditioner based on the engine status and / or the battery capacity.

[0059] Based on the method described in steps S101 to S103 above, it is possible to determine whether to start the vehicle air conditioner according to the vehicle's engine status and battery capacity, thereby reducing the risk of deep discharge and avoiding the battery being in a feeding state for a long time due to insufficient power, thereby extending the battery life and improving the overall stability of the vehicle system.

[0060] The above steps S101 to S103 are further explained below.

[0061] In some implementations of step S101, the vehicle air conditioner may obtain a CAN signal sent by the vehicle terminal via a CAN bus.

[0062] Among them, CAN signals mainly include engine speed signals and battery capacity signals.

[0063] Specifically, the engine speed can be detected by the vehicle's sensors, the battery capacity can be monitored by the vehicle's battery (such as a lithium battery) management system itself, and the detected engine speed information and capacity information can be sent to the vehicle's air conditioning system via the CAN bus in a specific data format.

[0064] It should be pointed out that the above examples about CAN signals are only schematic illustrations. In actual applications, technical personnel in this field can set the content of the CAN signals sent by the vehicle terminal according to specific scenarios. For example, it can also include ambient temperature signals, vehicle speed signals, fault code signals, etc., which are not limited here.

[0065] The above is a further description of step S101. The following is a further description of step S101.

[0066] In some implementations of the above step S102, the engine status of the vehicle may be acquired according to the CAN signal.

[0067] Specifically, when the engine speed is less than a preset speed threshold (such as 100 rpm), the engine is determined to be in an unstarted state; when the engine speed is greater than or equal to the preset speed threshold, the engine is determined to be in a started state.

[0068] Furthermore, in some implementations of step S103, the use status of the vehicle air conditioner can be controlled according to the engine status.

[0069] Among them, the use status of the vehicle air conditioner includes normal use status and prohibited use status. In the normal use status, the vehicle air conditioner can be started normally until the lithium battery itself is under-voltage protected and the vehicle is powered off. The vehicle air conditioner does not need to set the battery under-voltage protection; in the prohibited use status, the vehicle air conditioner cannot be started.

[0070] Furthermore, in some embodiments, when the engine is not started, the vehicle air conditioner can be controlled to be in normal use; when the engine is started, the use state of the vehicle air conditioner can be controlled based on the battery capacity.

[0071] Specifically, when the usage status of the vehicle air conditioner is controlled based on the battery capacity, when the battery capacity is greater than or equal to a preset capacity threshold (such as 50%), the vehicle air conditioner can be controlled to a normal usage state; when the battery capacity is less than the preset capacity threshold, the vehicle air conditioner can be controlled to a prohibited usage state.

[0072] Furthermore, in some embodiments, when the vehicle air conditioner is in a prohibited use state, a prohibited use prompt can be issued, such as displaying text prompts such as "Overhead air conditioner is prohibited from use", "Battery power is low, air conditioner is prohibited from use" on the dashboard, or controlling the air conditioner icon on the dashboard to flash, and voice broadcasts and pop-up prompts can be made through the vehicle multimedia system to attract the driver's attention.

[0073] In some embodiments, when the vehicle air conditioner is in a prohibited use state, the CAN signal sent by the vehicle terminal can be obtained again, and the battery capacity can be obtained based on the CAN signal. When the battery capacity is greater than or equal to a preset capacity threshold, the vehicle air conditioner can be controlled to switch to a normal use state, and a normal use prompt can be issued to remind the driver to turn on the air conditioner to prevent the lithium battery from being in a power supply state for a long time.

[0074] The above is a further description of step S103.

[0075] In some embodiments of the vehicle air-conditioning control method provided in the present application, in order to solve some problems that may exist in the air-conditioning program, such as inaccurate temperature control, abnormal wind speed adjustment, freezing, frequent errors, and compatibility issues with other vehicle systems, the vehicle air-conditioning can also communicate with the mobile terminal through the vehicle terminal to realize remote updating of the software program.

[0076] For example, the Internet of Vehicles system communicates with a server (such as an Internet of Vehicles service platform) through a mobile communication network or a wireless network. At the same time, the APP of a mobile terminal (such as a PC, mobile phone, tablet computer, etc.) also establishes a connection with the server to realize communication between the car air conditioner and the mobile terminal, thereby remotely updating the software of the car air conditioner through Over-The-Air Technology (OTA).

[0077] For details, see the attached Figure 2 , Figure 2 FIG. 1 is a flow chart of the main steps of a method for controlling a vehicle air conditioner according to another embodiment of the present application. Figure 2 As shown, it mainly includes the following steps S201 to S202.

[0078] Step S201: Obtain the program to be updated sent by the mobile terminal;

[0079] Specifically, users can view system prompts through the APP of the mobile terminal, download the latest software program provided by the server, and send the updated program to the car air conditioner through the Internet of Vehicles system, communication gateway system, T-BOX car terminal, and CAN bus, so that the car air conditioner can obtain the updated program sent by the mobile terminal.

[0080] Step S202: parsing the program to be updated, and sending the program to be updated to the module to be updated, so that the module to be updated is updated based on the program to be updated.

[0081] Among them, the vehicle air conditioner at least includes a main control module and a drive module.

[0082] Specifically, the main control module chip of the vehicle air conditioner can analyze the received program to be updated. If the program to be updated is the main control program (such as a control program used to optimize the main control module's control of the overall operating logic of the air conditioner, an update program for the temperature sensor data processing algorithm, etc.), the main control module will update its own software based on the program to be updated; if the program to be updated is not the main control program, the main control module will send the program to be updated to the drive module. When the drive module determines that the program to be updated is a driver program (such as a program used to adjust motor drive parameters, control fan speed, etc.), it will update its own software based on the program to be updated.

[0083] Among them, the main control module or the driving module needs to be updated based on the program to be updated when the operating state of the vehicle air conditioner is the standby state.

[0084] Because the system stability is high when the car air conditioner is in standby mode, and there are no complex running tasks in progress, the software program update process can be carried out in a relatively stable environment, reducing the risk of update failure due to interference from other running tasks. At the same time, the resource availability is high in the standby state, and most of the resources of the car air conditioning system are idle, which can be better allocated to the software program update process. And without high-power running activities, the probability of hardware failure or unexpected situations is low, and safety is guaranteed.

[0085] If the vehicle air conditioner is in operation or powered off, the update cannot be successful. In this case, you can wait until the vehicle air conditioner is in standby state before updating.

[0086] It should be pointed out that the above examples of modules to be updated in the vehicle air conditioner are only schematic illustrations. In actual applications, they may also include sensor modules, communication modules, power modules, etc. Those skilled in the art may set them according to specific needs, which is not limited here.

[0087] Furthermore, after the vehicle air conditioner is updated, the APP on the user's mobile terminal will prompt the user that the update is successful.

[0088] See attached Figure 3 , Figure 3 It is a main flow chart of a method for controlling a vehicle air conditioner according to an embodiment of the present application.

[0089] like Figure 3 As shown, the mobile terminal sends the program to be updated to the vehicle air conditioner through the vehicle terminal T-BOX;

[0090] The main control template of the vehicle air conditioner determines whether the program to be updated is the main control program. If so, it automatically updates the program to be updated in the standby state; otherwise, it sends the program to be updated to the drive module;

[0091] When the driving module determines that the program to be updated is a driving program, the program to be updated is automatically updated in a standby state based on the program to be updated.

[0092] Through the above implementation, software problems occurring in the vehicle air conditioner can be repaired in a timely manner, reducing the workload and maintenance costs of maintenance personnel, improving maintenance efficiency, enhancing safety, and improving the user experience.

[0093] Furthermore, in some embodiments, the vehicle air conditioner can obtain the control instruction sent by the mobile terminal and control the vehicle air conditioner based on the control instruction. The use status and / or operation status of the vehicle air conditioner can also be sent to the mobile terminal.

[0094] Specifically, users can control the opening and control of the car air conditioner through the APP of the mobile terminal, and can check the usage status, operating status, faults, maintenance reminders and other information of the car air conditioner through the APP.

[0095] The above is an explanation of the control method of the vehicle air conditioner provided in this application.
