[0035] Next, the technical solutions in the embodiments of this specification will be clearly and completely described in conjunction with the drawings in the embodiments of this specification. Obviously, the described embodiments are only a part of the embodiments of this specification, rather than all the embodiments. Based on the embodiments in this specification, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the embodiments of this specification.

[0036] Currently, when forklifts, excavators and other engineering vehicles are operating, the engine not only needs to provide the basic power required by the engineering vehicle, such as driving power and the power of the hydraulic cylinder to meet engineering operations, but also needs to provide the power of the air conditioner compressor. For existing vehicles, in order to improve the driving experience of the driver, a dual air conditioner system is usually set up, including a driving air conditioner and a parking air conditioner. In order to ensure the refrigeration effect, the driving air conditioner and the parking air conditioner are usually turned on at the same time, resulting in too high an engine load when the engine provides the above three kinds of power for the vehicle at the same time, which easily leads to a reduction in the engine life.

[0037] To solve the above technical problems, Embodiment 1 of this specification provides a flowchart of a control method for a dual air conditioner system, as Figure 1As shown, the method flow specifically includes the following steps:

[0038] S202: Obtain vehicle information characterizing the vehicle operation state.

[0039] In the embodiments of this specification, the vehicle mainly refers to engineering vehicles, such as forklifts, excavators, cranes, etc. The vehicle operation state includes a high-load operation state and a non-high-load operation state. The high-load operation state can also be called an engineering operation state, and the non-high-load state can also be called a non-engineering operation state. The high-load operation state specifically means that the vehicle simultaneously provides driving power to meet the power for engineering operations and the power for the driving air conditioner compressor. Therefore, in the embodiments of this specification, the vehicle information can be numerical information reflecting the load of the vehicle working device.

[0040] S204: Determine whether the vehicle is in a high-load operation state according to the vehicle information.

[0041] In the embodiments of this specification, determining whether the vehicle is in a high-load operation state can be to determine whether the total power provided by the vehicle working device at the current moment includes the above-mentioned three kinds of power, and whether the provision of this total power has affected the service life of the vehicle working device.

[0042] S206: If the vehicle is in a high-load operation state, turn off the driving air conditioner and turn on the parking air conditioner.

[0043] In the embodiments of this specification, if through the above judgment process, it can be determined that the vehicle is in a high-load operation state, then turn off the driving air conditioner and turn on the parking air conditioner. Since the compression power of the parking air conditioner is provided by an external energy storage device, and the compression power of the driving air conditioner is provided by the vehicle working device, after turning off the driving air conditioner, the vehicle working device no longer needs to provide the compression power of the driving air conditioner, thereby reducing the load of the vehicle working device. At the same time, such a setting can also ensure that the vehicle driver is in a temperature-appropriate driving environment.

[0044] It should be understood that the order of some steps in the method described in one or more embodiments of this specification can be interchanged according to actual needs, or some steps can also be omitted or deleted.

[0045] Figure 1 For the method shown, by obtaining vehicle information characterizing the vehicle operation state, determining whether the vehicle is in a high-load operation state according to the vehicle information, and if the vehicle is in a high-load operation state, turning off the driving air conditioner and turning on the parking air conditioner. Since the power of the driving air conditioner is provided by the vehicle working device and the power of the parking air conditioner is provided by an external energy storage device, therefore, when the vehicle is in a high-load operation state, turning off the driving air conditioner and turning on the parking air conditioner can reduce the load of the vehicle working device, thereby being beneficial to extending the service life of the vehicle working device.

[0046] Based on Figure 2 the method shown above, the embodiments of this specification also provide a specific implementation of this method, which will be specifically described below.

[0047] The control method of the dual air-conditioning system further includes S208: If the vehicle is not in the high-load operation state, turn on the driving air conditioner and turn off the parking air conditioner.

[0048] In the embodiments of this specification, it can be understood that if the total power provided by the vehicle working device does not affect the service life of the vehicle working device, it indicates that the vehicle is not in the high-load operation state and the vehicle working device is operating well. Therefore, turning on the driving air conditioner at this time will not affect the service life of the vehicle working device. At the same time, turning off the parking air conditioner is beneficial to saving energy of external energy storage devices such as batteries, or the battery can also be charged at this time to reserve energy.

[0049] Preferably, the vehicle information includes: the pressure value of the working device; the judgment of whether the vehicle is in the high-load operation state according to the vehicle information specifically includes: if the pressure value of the working device is greater than the first preset pressure threshold, the vehicle is in the high-load operation state; if the pressure value of the working device is not greater than the first preset pressure threshold, the vehicle is in the non-high-load operation state.

[0050] In the embodiments of this specification, it is judged whether the vehicle working device is in the high-load operation state by whether the pressure value provided by the vehicle working device is greater than the first preset pressure threshold, and the first preset pressure threshold is preset according to the actual situation of different engineering vehicles.

[0051] Preferably, if the vehicle is in the high-load operation state, the dual air-conditioning system control method further includes: when the driving air conditioner is in the off state and the parking air conditioner is in the on state, monitoring the continuous duration that the pressure value of the working device is less than the second preset pressure threshold; wherein, the second preset pressure threshold is less than or equal to the first preset pressure threshold; if the continuous duration reaches the first preset duration threshold, turn on the driving air conditioner and turn off the parking air conditioner.

[0052] In the embodiments of this specification, since the compression power of the parking air conditioner is provided by an external energy storage device, and this external energy storage device needs to store energy by itself, therefore, this external energy storage device may not be able to provide compression power for the parking air conditioner for a long time. Thus, when the vehicle is in a high-load operation state, after turning off the driving air conditioner and turning on the parking air conditioner, it is necessary to monitor the pressure value of the vehicle working device. If the monitored pressure value of the vehicle working device is continuously less than a second preset threshold for a period of time, it indicates that the vehicle has entered a non-high-load operation state. That is, at this time, the vehicle working device can provide the compression power required for the driving air conditioner again. That is, at this time, the driving air conditioner can be turned on again and the parking air conditioner can be turned off. At the same time, the external energy storage device of the parking air conditioner can store energy. Among them, the second preset threshold is less than or equal to the first preset threshold, and the second preset threshold is set according to the vehicle type and the vehicle's own conditions according to the actual situation.

[0053] Preferably, the dual air conditioner system control method further includes: if it is determined according to the vehicle information that the vehicle is in a non-operating state, then turn on the parking air conditioner.

[0054] In the embodiments of this specification, the vehicle operation state means that the vehicle has been started, or the vehicle working device has been turned on. The vehicle non-operation state means that the vehicle has not been started, or the vehicle working device has not been turned on. That is, the vehicle working device does not provide any power. It is judged whether the vehicle is in a non-operating state according to whether the vehicle is started or whether the vehicle provides power. If the vehicle information indicates that the vehicle has not been started, or the vehicle working device does not provide any power, it indicates that the vehicle is in a non-operating state. When the vehicle has not been started, the vehicle working device cannot provide the compression power required for the driving air conditioner. Therefore, to improve the driving experience, the parking air conditioner can be turned on, and the compression power of this parking air conditioner is provided by an external energy storage device.

[0055] Preferably, turning off the driving air conditioner and turning on the parking air conditioner includes: controlling the driving air conditioner and the parking air conditioner to be turned on simultaneously within a second preset duration; when the second preset duration is reached, turning off the driving air conditioner and turning on the parking air conditioner.

[0056] In the embodiments of this specification, when switching between the two modes of the driving air conditioner and the parking air conditioner, in order to ensure the driver's driving experience, the driving air conditioner and the parking air conditioner can be set to be turned on simultaneously for a period of time, and then the driving air conditioner or the parking air conditioner can be turned off according to the need. Thus, it effectively avoids the situation that there is no air conditioner working in the cab during the time interval between turning off the driving air conditioner and turning on the parking air conditioner, which is beneficial to improving the driver's driving experience.

[0069] If the duration reaches the first preset duration threshold, turn on the driving air conditioner and turn off the parking air conditioner.

[0070] Furthermore, the judgment module is further configured to: if it is determined according to the vehicle information that the vehicle is in a non-operating state, turn on the parking air conditioner.

[0071] Furthermore, the turning off the driving air conditioner and turning on the parking air conditioner includes:
