[0038] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention, but should not be construed as limiting the present invention.

[0039] An embodiment of the present invention provides a vehicle. Referring to Figure 1 , the vehicle includes: an air conditioner ( Figure 1 not shown in

[0040] ), and an electric heating film 00 disposed in the vehicle cabin. Figure 2, the air conditioner 10 includes: a blower 11, a water pump 12, an electric heater 13, and a heater core 14 connected in sequence. The blower 11 can be arranged at the entrance of the housing of the air conditioner and can blow air to the heater core 14.

[0041] When the vehicle heats the passenger compartment of the vehicle through the air conditioner, the electric heater 13 can heat the coolant. The heated coolant flows through the heater core 14 under the action of the water pump 12 and exchanges heat with the air blown through the heater core 14, thereby heating the air. The heated air is blown towards the passenger compartment, thereby increasing the temperature inside the passenger compartment and achieving heating of the passenger compartment.

[0042] Optionally, the electric heater 13 can be a WPTC (water - heated positive temperature coefficient). The electric heating film 00 can be arranged on at least one of the following components in the passenger compartment: carpet, steering wheel, seat, ceiling, and coat rack. For example, referring to Figure 1 , the electric heating film 00 is arranged on the carpet, steering wheel, seat, ceiling, and coat rack in the passenger compartment. The electric heating film can be made of graphene or a material containing graphene. The vehicle can be an electric vehicle.

[0043] Figure 3 is a flowchart of a method for controlling an air conditioner of a vehicle provided by an embodiment of the present invention. This method is applied to a controller in the vehicle, and the vehicle further includes an electric heating film arranged in the passenger compartment. Referring to Figure 3 , the method includes:

[0044] Step 301, in response to a heating instruction for the air conditioner, control the air conditioner to heat according to a target air outlet temperature.

[0045] The heating instruction can be a voice instruction issued by the driver or passenger of the vehicle, or can be sent by a mobile terminal having a communication connection with the vehicle, or can be triggered by a touch operation on a temperature adjustment button for the air conditioner of the vehicle. Optionally, the temperature adjustment button can be a physical button or a virtual control.

[0046] Step 302, control the electric heating film to heat.

[0047] When it is necessary to heat the passenger compartment, the controller can also control the electric heating film to heat. After the electric heating film heats, it can also provide heat to the passenger compartment. In this way, the electric heating film can assist the air conditioner to heat the passenger compartment, thereby quickly increasing the temperature inside the passenger compartment.

[0048] Step 303, after the temperature in the passenger compartment is greater than a first temperature threshold, control the air outlet temperature of the air conditioner not to be higher than the target air outlet temperature.

[0049] In an embodiment of the present invention, after the temperature in the vehicle cabin is greater than the first temperature threshold, the controller can cause the electric heating film to continue heating to maintain the temperature in the vehicle cabin to a certain extent. Moreover, the controller can also control the air outlet temperature of the air conditioner not to be higher than the target air outlet temperature. In this way, it can ensure that the energy consumption of the vehicle is reduced to a certain extent while maintaining the temperature in the vehicle cabin as much as possible.

[0050] In summary, the embodiment of the present invention provides an air conditioner control method for a vehicle. When the vehicle responds to a heating instruction for the air conditioner, it can control the air conditioner to heat according to the target air outlet temperature. And the vehicle also includes an electric heating film and can control the electric heating film to heat. That is, the air conditioner and the electric heating film can heat the vehicle cabin simultaneously. Compared with only heating the vehicle cabin by the air conditioner, the method provided by the embodiment of the present invention can effectively increase the temperature rise rate of the vehicle cabin. And after the temperature in the vehicle cabin is greater than the first temperature threshold, the vehicle can control the air outlet temperature of the air conditioner not to be higher than the target air outlet temperature. Thus, the energy consumption of the vehicle can be reduced while maintaining the temperature in the vehicle cabin to a certain extent.

[0051] Figure 4 is a flowchart of an air conditioner control method for a vehicle provided by an embodiment of the present invention. This method is applied to a controller (such as an air conditioner controller) in the vehicle, and the vehicle also includes an electric heating film arranged in the vehicle cabin. Refer to Figure 4 , this method may include:

[0052] Step 401, in response to a heating instruction for the air conditioner, control the air conditioner to heat according to the target air outlet temperature.

[0053] When the driver and passengers need the air conditioner to heat to increase the temperature in the vehicle cabin, they can trigger the controller of the vehicle to control the air conditioner to heat. For example, the driver and passengers can issue a heating instruction in the form of voice for indicating the air conditioner to heat, or can send a heating instruction to the vehicle through a mobile terminal, or can touch the temperature adjustment button of the air conditioner. Optionally, the temperature adjustment button can be a physical button or a virtual control.

[0054] Correspondingly, the controller can control the air conditioner to heat in response to a heating instruction in the form of voice, or a heating instruction sent by a mobile terminal, or a heating instruction triggered by a touch operation on the temperature adjustment button.

[0055] In an embodiment of the present invention, the target air outlet temperature depends on the reference heating gear of the heater. The reference heating gear can be pre-stored by the controller. For example, it can be the highest heating gear of the heater.

[0056] Step 402, obtain the current working mode of the air conditioner.

[0057] The operating modes of the air conditioner can be: defrosting mode, non - defrosting mode, or one - key defrosting mode. The non - defrosting modes include: face - blowing mode, face - and - foot - blowing mode, and foot - blowing mode. In the defrosting mode, the air conditioner can blow warm air towards the front windshield of the vehicle to increase the temperature of the front windshield surface, thereby melting the frost. In the one - key defrosting mode, the vehicle can automatically adjust the air volume of the air conditioner to enhance the defrosting and defogging speed.

[0058] Step 403: When the operating mode of the air conditioner is not the one - key defrosting mode, detect whether the vehicle meets the start conditions of the electric heating film.

[0059] The start conditions of the electric heating film can include: the range - extender mode is turned on, the ambient temperature of the vehicle is within a temperature range, and the heating function of any component equipped with the electric heating film is in the on state. Among them, the temperature range can be pre - stored in the controller, for example, it can be [-15°C, 5°C]. °C represents degrees Celsius.

[0060] Optionally, a range - extender mode activation control can be set in the vehicle, and this activation control is default in the off state. If the driver or passenger needs to turn on the range - extender mode, they can touch this activation control. Correspondingly, the controller can respond to the touch operation on this activation control and turn on the range - extender mode of the vehicle.

[0061] Optionally, an activation control corresponding to the heating function of each component can be displayed in the vehicle, and this activation control is default in the off state. If the driver or passenger needs to control the electric heating film wrapped on the component to heat, they can touch the activation control corresponding to this component. After the controller receives the touch operation on this activation control, it can control the heating function of this component to be in the on state. For example, the central control screen of the vehicle can display a seat - heating activation control. After the controller receives the touch operation of the driver or passenger on this seat - heating activation control, it can turn on the heating function of this seat, that is, make the heating function in the on state.

[0062] In the embodiment of the present invention, a first temperature sensor can be set on the body surface of the vehicle. This first temperature sensor can detect the ambient temperature and send the ambient temperature to the controller. Then the controller can receive the ambient temperature and judge whether the ambient temperature is within the temperature range.

[0063] Step 404: Control the electric heating film to heat.

[0064] After the controller determines that the vehicle meets the start conditions of the electric heating film, it can control the electric heating film to heat.

[0065] In the embodiment of the present invention, the controller can effectively increase the temperature rise rate of the passenger compartment by controlling the air conditioner and the electric heating film to heat simultaneously, thereby quickly increasing the temperature in the passenger compartment.

[0066] Step 405: Obtain the temperature inside the vehicle cabin.

[0067] Optionally, a second temperature sensor may be provided inside the vehicle cabin. The second temperature sensor can detect the temperature inside the vehicle cabin and send the temperature inside the vehicle cabin to the controller.

[0068] Step 406: Determine whether the temperature inside the vehicle cabin is greater than the first temperature threshold.

[0069] When the temperature inside the vehicle cabin is greater than the first temperature threshold, the controller may execute Step 407. When the temperature inside the vehicle cabin is less than or equal to the first temperature threshold, the controller may execute Step 408. The first temperature threshold may be pre-stored in the controller. For example, the first temperature threshold may be a temperature at which a person feels relatively comfortable.

[0070] Step 407: Control the air outlet temperature of the air conditioner not to be higher than the target air outlet temperature.

[0071] When the temperature inside the vehicle cabin is greater than the first temperature threshold, the controller can control the air outlet temperature of the air conditioner not to be higher than the target air outlet temperature.

[0072] Since the air conditioner and the electric heating film heat simultaneously to increase the temperature inside the vehicle cabin, and the energy consumption of the electric heating film is lower than that of the air conditioner, when the temperature inside the vehicle cabin is greater than the first temperature threshold, the controller can control the air outlet temperature of the air conditioner not to be higher than the target air outlet temperature. In this way, it is possible to ensure that while maintaining the temperature inside the vehicle cabin as much as possible, the energy consumption of the vehicle is reduced to a certain extent.

[0073] In an embodiment of the present invention, the controller controls the heater based on the working mode of the air conditioner to control the air outlet temperature of the air conditioner not to be higher than the target air outlet temperature. The working mode is a defrosting mode or a non-defrosting mode.

[0074] Specifically, if the working mode of the air conditioner is a non-defrosting mode, in an optional implementation, the controller can directly control the electric heater to stop working to control the current air outlet temperature of the air conditioner to be lower than the target air outlet temperature.

[0075] It can be understood that after the electric heating stops working, the temperature of the coolant flowing through the heater core will not drop very low immediately, but can still heat the vehicle cabin. Therefore, at this time, the controller can control the blower air volume gear to the first gear to maximize the use of the heat of the coolant to heat the vehicle cabin. The first gear can be pre-stored in the controller.

[0076] As the temperature of the coolant flowing through the heater core gradually decreases, the outlet air temperature of the corresponding air conditioner also gradually decreases. To avoid a decrease in the temperature inside the vehicle cabin due to too low an outlet air temperature, the controller can monitor the outlet air temperature of the air conditioner and, when the outlet air temperature of the air conditioner is less than or equal to the second temperature threshold, control the blower to stop operating. Herein, the second temperature threshold can be pre-stored by the controller.

[0077] Optionally, when the blower stops operating, the controller can also control the water pump to stop operating to further reduce the energy consumption of the vehicle.

[0078] In another alternative implementation, the controller can obtain the ambient temperature of the vehicle, obtain the target heating gear of the heater based on the ambient temperature, and control the heater to heat according to the target heating gear. Herein, the target heating gear is negatively correlated with the ambient temperature. The outlet air temperature of the air conditioner is positively correlated with the target heating gear. That is to say, the controller can adjust the outlet air temperature of the air conditioner according to the ambient temperature. When the temperature inside the vehicle cabin is greater than the first temperature threshold (for example, when the temperature inside the vehicle cabin reaches the comfortable temperature felt by the driver and passengers), the vehicle automatically adjusts the heating capacity of the air conditioner. Thereby, while maintaining the temperature inside the vehicle cabin, the energy consumption of the air conditioner can be reduced to a certain extent, and further the energy consumption of the vehicle can be reduced.

[0079] For example, when the ambient temperature is less than -20 °C, the heating gear of the air conditioner can remain unchanged at the current heating gear, that is, at this time, the outlet air temperature of the air conditioner remains the target outlet air temperature. Assuming the current heating gear is gear 3, then when the ambient temperature is greater than or equal to -20 °C and less than -10 °C, the target heating gear can be gear 2. Correspondingly, the controller can adjust the heating gear of the electric heater of the air conditioner to gear 2. When the ambient temperature is greater than or equal to -10 °C and less than 0 °C, the target heating gear can be gear 1. Correspondingly, the controller can adjust the heating gear of the electric heater of the air conditioner to gear 1. Herein, the power of the electric heater when the heating gear is gear 3 is greater than the power when the heating gear is gear 2, and the power when the heating gear is gear 2 is greater than the power when the heating gear is gear 1.

[0080] Optionally, the controller can pre-store the correspondence between temperature and gear, and can determine the gear corresponding to the ambient temperature of the vehicle in the correspondence as the target heating gear of the heater. The power of the electric heater is positively correlated with the heating gear of the electric heater.

[0081] In an embodiment of the present invention, if the operating mode of the air conditioner is the defrosting mode, the controller can control the heater to heat at a target power, so as to control the air outlet temperature of the air conditioner to be lower than the target air outlet temperature, thereby reducing the heating capacity of the air conditioner. Wherein, the target power can be pre-stored in the controller, and the target power is less than the power when the heating gear of the electric heater is at gear 1. For example, it can be 800 watts (W).

[0082] Optionally, the controller can also lower the blower gear to the second gear and adjust the circulation mode to the external circulation. Wherein, the air volume of the second gear outlet is less than that of the first gear outlet, and the second gear can be pre-stored in the controller. For example, the first gear of the blower can be gear 3, and the second gear can be gear 2.

[0083] Step 408: Control the air conditioner to continue heating according to the target air outlet temperature.

[0084] When the temperature in the vehicle cabin is less than or equal to the first temperature threshold, the controller can control the air conditioner to operate at the current heating capacity.

[0085] Step 409: After detecting that the electric heating film meets the shutdown condition, control the electric heating film to stop heating.

[0086] The shutdown condition can be satisfied when the range extender mode is turned off, or the ambient temperature is outside the temperature range, or the heating functions of all components equipped with the electric heating film are in the off state, or the current operating mode of the air conditioner is the one-key defrosting mode.

[0087] It can be understood that the sequence of steps of the vehicle air conditioner control method provided by the embodiments of the present invention can be appropriately adjusted, and the steps can also be increased or decreased accordingly according to the situation. For example, step 402 can be deleted according to the situation; or step 409 can also be deleted according to the situation. Any method of change that can be easily thought of by any person skilled in the art within the technical scope disclosed in this application should be covered within the protection scope of this application, so it will not be elaborated here.

[0088] In summary, the embodiments of the present invention provide a vehicle air conditioner control method. The vehicle responds to a heating instruction for the air conditioner and can control the air conditioner to heat according to the target air outlet temperature. The vehicle also includes an electric heating film and can control the electric heating film to heat. That is, the air conditioner and the electric heating film can heat the vehicle cabin simultaneously. Compared with heating the vehicle cabin only through the air conditioner, the method provided by the embodiments of the present invention can effectively increase the temperature rise rate of the vehicle cabin. And after the temperature in the vehicle cabin is greater than the first temperature threshold, the vehicle can control the air outlet temperature of the air conditioner not to be higher than the target air outlet temperature. Thus, the energy consumption of the vehicle can be reduced while maintaining the temperature in the vehicle cabin to a certain extent.
