[0030] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0031] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0032] According to an embodiment of this application, an embodiment of a vehicle defrosting operation method is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0033] Figure 1 This is a flowchart of a vehicle defrosting operation method according to an embodiment of this application, such as... Figure 1 As shown, the method includes the following steps.

[0034] Step S101: In response to the vehicle's defrost command, obtain the vehicle's multi-dimensional state parameters.

[0035] In the technical solution provided in step S101 of this application, the aforementioned multi-dimensional state parameters can be used to characterize the defrosting needs of the vehicle. For example, these multi-dimensional state parameters may include, but are not limited to: driver's side fan speed setting, passenger side fan speed setting, driver's side temperature setting, passenger side temperature setting, ambient temperature of the vehicle's current environment, the vehicle's current driving gear, and the vehicle's air conditioning circulation mode. These are merely illustrative examples and do not limit the scope of these multi-dimensional state parameters. The aforementioned defrosting command can control the vehicle to activate its defrosting strategy. For example, the defrosting command can be triggered via a button on the vehicle's air conditioning panel.

[0036] In this embodiment, in response to a defrost command from the vehicle, multi-dimensional status parameters of the vehicle are acquired. For example, after the vehicle receives a defrost command, the Vehicle Control Unit (VCU) acquires data uploaded by multiple sensors and control units of the vehicle via the vehicle's Controller Area Network (CAN) bus, thereby obtaining the aforementioned multi-dimensional status parameters. These multiple sensors and control units include, but are not limited to, the air conditioning control unit, the ambient temperature sensor, and the transmission control unit.

[0037] Step S102: Based on multi-dimensional state parameters, determine the defrosting mode that the vehicle is to enter.

[0038] In the technical solution provided in step S102 of this application, the defrosting mode can be used to characterize the defrosting level of the vehicle. For example, the defrosting mode may include a first-level defrosting mode and a second-level defrosting mode. The first-level defrosting mode corresponds to a higher defrosting level than the second-level defrosting mode. For example, the first-level defrosting mode may be a powerful defrosting mode, and the second-level defrosting mode may be a normal defrosting mode.

[0039] In this embodiment, after obtaining the multi-dimensional state parameters, the defrosting mode to be entered by the vehicle can be determined based on these parameters. For example, according to the parameter content in the multi-dimensional state parameters, it can be determined that the defrosting mode to be entered by the vehicle is either a level one defrosting mode or a level two defrosting mode.

[0040] Optionally, the parameters in the aforementioned multi-dimensional state parameters can be compared with the defrosting conditions corresponding to the first-level defrosting mode to obtain a comparison result. If the comparison result indicates that the parameters in the aforementioned multi-dimensional state parameters meet the defrosting conditions corresponding to the first-level defrosting mode, then the defrosting mode to be entered by the vehicle is determined to be the first-level defrosting mode. Otherwise, the defrosting mode to be entered by the vehicle is determined to be the second-level defrosting mode.

[0041] Step S103: Generate defrost control instructions in defrost mode.

[0042] In the technical solution provided in step S103 of this application, the defrosting control command can be used to characterize the rules for the vehicle to perform a defrosting operation. Optionally, the defrosting control command can be used to control multiple devices in the vehicle to perform a defrosting operation. For example, the multiple devices may include, but are not limited to, a motor, an engine, and an electric water pump.

[0043] In this embodiment, after determining the defrost mode, a defrost control command under the defrost mode can be generated. For example, when the defrost mode is the first-level defrost mode mentioned above, a first defrost control command corresponding to the first-level defrost mode can be generated; when the defrost mode is the second-level defrost mode mentioned above, a second defrost control command corresponding to the second-level defrost mode can be generated.

[0044] Step S104: In response to the defrost control command, control the vehicle to perform a defrost operation in defrost mode.

[0045] In the technical solution provided in step S104 of this application, after generating the defrost control command, the vehicle can be controlled to perform a defrost operation in defrost mode in response to the defrost control command. For example, when the defrost control command is a first defrost control command, multiple devices in the vehicle can be controlled to perform defrost operations according to the first defrost control command; when the defrost control command is a second defrost control command, multiple devices in the vehicle can be controlled to perform defrost operations according to the second defrost control command. The defrosted vehicle can then meet the defrost requirements represented by the aforementioned multi-dimensional state parameters.

[0046] In steps S101 to S104 of this application, in response to a vehicle's defrosting command, multi-dimensional state parameters of the vehicle are acquired; based on the multi-dimensional state parameters, the defrosting mode to be entered by the vehicle is determined; a defrosting control command in the defrosting mode is generated; and in response to the defrosting control command, the vehicle is controlled to perform a defrosting operation in the defrosting mode. In other words, in this embodiment, by acquiring the vehicle's multi-dimensional state parameters, the defrosting mode to be entered by the vehicle can be determined, and based on the defrosting mode, a defrosting control command can be generated to control the vehicle to perform a defrosting operation. That is, this application can determine the defrosting mode to be entered by the vehicle based on its multi-dimensional state parameters, thereby achieving the goal of adaptively adjusting the vehicle's defrosting mode according to the defrosting needs of vehicles in different regions. This solves the technical problem of low scene adaptability of the vehicle's defrosting mode, and thus achieves the technical effect of improving the scene adaptability of the vehicle's defrosting mode.

[0047] The method described in this embodiment will be further described below.

[0048] As an optional embodiment, step S102, based on multi-dimensional state parameters, determines the defrosting mode to be entered by the vehicle, including: comparing the multi-dimensional state parameters with the defrosting conditions corresponding to the first-level defrosting mode to obtain a comparison result; in response to the comparison result indicating that the multi-dimensional state parameters meet the defrosting conditions, determining the vehicle's defrosting mode as the first-level defrosting mode, or in response to the comparison result indicating that the multi-dimensional state parameters do not meet the defrosting conditions, determining the defrosting mode as the second-level defrosting mode, wherein the defrosting level corresponding to the first-level defrosting mode is higher than the defrosting level corresponding to the second-level defrosting mode.

[0049] In this embodiment, the defrosting conditions described above can be used to characterize the conditions required to enter the first-level defrosting mode. For example, the defrosting conditions can be the conditions required to satisfy the multi-dimensional state parameters.

[0050] Optionally, after obtaining the multidimensional state parameters, the multidimensional state parameters are compared with the defrosting conditions corresponding to the first-level defrosting mode to obtain the comparison results. For example, by comparing each parameter in the multidimensional state parameters with the corresponding condition in the defrosting conditions, the comparison results can be obtained.

[0051] Optionally, after obtaining the comparison result, in response to the comparison result indicating that the multidimensional state parameters meet the defrosting conditions, the vehicle's defrosting mode is determined to be a Level 1 defrosting mode; or, in response to the comparison result indicating that the multidimensional state parameters do not meet the defrosting conditions, the defrosting mode is determined to be a Level 2 defrosting mode. For example, when multiple parameters in the aforementioned multidimensional state parameters all meet the aforementioned defrosting conditions, the defrosting mode can be determined to be the aforementioned Level 1 defrosting mode; when multiple parameters in the aforementioned multidimensional state parameters only partially meet the aforementioned defrosting conditions, or all of them do not meet the aforementioned defrosting conditions, the defrosting mode can be determined to be the aforementioned Level 2 defrosting mode. The defrosting level corresponding to the Level 1 defrosting mode is higher than the defrosting level corresponding to the Level 2 defrosting mode.

[0052] In this step, by comparing the multidimensional state parameters with the defrosting conditions, it can be determined whether the defrosting mode to be entered by the vehicle is a first-level defrosting mode or a second-level defrosting mode. This achieves the goal of quickly determining the defrosting mode that matches the current defrosting needs of the vehicle, thereby improving the efficiency and accuracy of defrosting mode determination.

[0053] As an optional implementation method, the defrosting conditions corresponding to the first-level defrosting mode include at least the following: the air volume setting level on the driver's side of the vehicle is greater than or equal to the preset air volume setting level; the air volume setting level on the passenger side of the vehicle is greater than or equal to the preset air volume setting level; the temperature setting value on the driver's side of the vehicle is greater than or equal to the temperature setting threshold; the temperature setting value on the passenger side of the vehicle is greater than or equal to the temperature setting threshold; the ambient temperature of the current environment where the vehicle is located is lower than the temperature threshold; the current gear position of the vehicle is neutral or park; and the air conditioning circulation mode of the vehicle is internal circulation mode.

[0054] In this embodiment, the defrosting conditions corresponding to the first-level defrosting mode include: the airflow setting level on the driver's side of the vehicle is greater than or equal to the preset airflow setting level. For example, the airflow setting level on the driver's side of the vehicle is greater than or equal to "level 7". Here, the airflow level is only illustrative and is not specifically limited.

[0055] Optionally, the defrosting conditions corresponding to the above-mentioned Level 1 defrosting mode also include: the airflow setting level on the passenger side of the vehicle is greater than or equal to the preset airflow setting level. For example, the airflow setting level on the passenger side of the vehicle is greater than or equal to "Level 7". Here, the airflow level is only for illustrative purposes and is not specifically limited.

[0056] Optionally, the defrosting conditions corresponding to the above-mentioned Level 1 defrosting mode also include: the temperature setting value on the driver's side of the vehicle is greater than or equal to the temperature setting threshold. For example, the temperature setting value on the driver's side of the vehicle is greater than or equal to "32℃". This temperature setting value is only for illustrative purposes and is not specifically limited.

[0057] Optionally, the defrosting conditions corresponding to the above-mentioned Level 1 defrosting mode also include: the temperature setting value on the passenger side of the vehicle is greater than or equal to the temperature setting threshold. For example, the temperature setting value on the passenger side of the vehicle is greater than or equal to "32℃". This temperature setting value is only for illustrative purposes and is not specifically limited.

[0058] Optionally, the defrosting conditions corresponding to the above-mentioned Level 1 defrosting mode also include: the ambient temperature of the vehicle's current environment is lower than a temperature threshold. For example, the ambient temperature of the vehicle's current environment is lower than "-14℃". This ambient temperature is only an example and is not a specific limitation.

[0059] Optionally, the defrosting conditions corresponding to the above-mentioned first-level defrosting mode also include: the vehicle is currently in neutral (e.g., N gear) or park (e.g., P gear). For example, the vehicle is currently in a non-driving state or a stationary state.

[0060] Optionally, the defrosting conditions corresponding to the above-mentioned Level 1 defrosting mode also include: the vehicle's air conditioning recirculation mode is set to internal recirculation mode. For example, the vehicle's air conditioning system closes the air exchange channel between the outside and inside of the vehicle, and only recirculates the air inside the vehicle.

[0061] In this step, by setting the defrosting conditions corresponding to the first-level defrosting mode and comparing the vehicle's multi-dimensional status parameters with the defrosting conditions, it is possible to quickly determine whether the vehicle has entered the first-level defrosting mode, thereby improving the efficiency of defrosting mode determination.

[0062] As an optional embodiment, when the defrosting mode is the first-level defrosting mode, a defrosting control command in the defrosting mode is generated, including: generating a first motor control command, a first engine control command, a first ignition control command, and a water pump control command based on the first-level defrosting mode. The first motor control command controls the rotational speed of the motor in the vehicle to a first rotational speed; the first engine control command controls the torque of the engine in the vehicle to a first torque; the first ignition control command controls the engine to delay ignition; and the water pump control command controls the duty cycle of the water pump in the vehicle. The water pump is used to transfer the engine's waste heat to the vehicle's air conditioning system to provide a heat source for the vehicle's windshield. The first motor control command, the first engine control command, the first ignition control command, and the water pump control command are then fused to obtain the first defrosting control command.

[0063] In this embodiment, the aforementioned first motor control command can be used to control the speed of the motor in the vehicle to a first speed. For example, the first speed can be 2000 rpm; this speed value is only illustrative and not specifically limited.

[0064] Optionally, the aforementioned first engine control command can be used to control the torque of the engine in the aforementioned vehicle to a first torque. For example, the aforementioned first torque can be calculated using the following formula (1).

[0065] (1)

[0066] Where T can be used to represent the torque of the engine; P_total can be used to represent the total power required by the entire vehicle system; and n can be used to represent the speed of the motor. The total power required by the entire vehicle system may include, but is not limited to: the power of the DC-DC converter (DCDC), the power of the positive temperature coefficient heater (PTC), and the battery charging power, etc.

[0067] Optionally, the aforementioned first ignition control command can be used to control the engine's delayed ignition. For example, a delayed ignition command can be sent to the engine through the Engine Management System (EMS) to adjust the engine's ignition advance angle and control the engine's minimum thermal efficiency.

[0068] Optionally, the aforementioned water pump control commands can be used to control the duty cycle of the water pump in the vehicle, thereby adjusting the water pump motor speed and controlling the coolant circulation flow rate. For example, the aforementioned duty cycle can be obtained from Table 1 below.

[0069] Table 1 Relationship between Engine Coolant Temperature and Water Pump Duty Cycle

[0070]

[0071] Optionally, the water pump can be used to transfer waste heat from the engine to the vehicle's air conditioning system, providing a heat source for the vehicle's windshield. For example, the water pump can deliver coolant flowing through the engine to the heater core of the air conditioning system.

[0072] Optionally, when the defrosting mode is Level 1 defrosting mode, the first motor control command, first engine control command, first ignition control command, and water pump control command can be generated via the VCU based on the Level 1 defrosting mode. Optionally, after generating the first motor control command, first engine control command, first ignition control command, and water pump control command, the first motor control command, first engine control command, first ignition control command, and water pump control command can be fused to obtain the first defrosting control command. For example, by using the VCU to write the first motor control command, first engine control command, first ignition control command, and water pump control command into the same fused command set, a first fused command set can be obtained, and the first fused command set can be determined as the first defrosting control command.

[0073] In this step, when the defrosting mode is Level 1, a first motor control command, a first engine control command, a first ignition control command, and a water pump control command can be generated. Based on the first motor control command, the first engine control command, the first ignition control command, and the water pump control command, a first defrosting control command can be obtained, thus providing the command basis for the vehicle to perform the defrosting operation.

[0074] As an optional embodiment, when the defrosting mode is a two-level defrosting mode, a defrosting control command is generated in the defrosting mode, including: generating a second motor control command, a second engine control command, and a second ignition control command based on the two-level defrosting mode, wherein the second motor control command is used to control the motor speed to a second speed, which is less than a first speed; the second engine control command is used to control the engine torque to a second torque, which is greater than a first torque; and the second ignition control command is used to control the engine to ignite normally; the second motor control command, the second engine control command, and the second ignition control command are fused to obtain the second defrosting control command.

[0075] In this embodiment, the second motor control command can be used to control the motor speed to a second speed, which is less than the first speed. For example, the second speed can be 1200 rpm. This speed value is only illustrative and not specifically limited.

[0076] Optionally, the second engine control command can be used to control the torque of the engine to be a second torque, which is greater than the first torque. For example, the second torque can be calculated using the formula (1) above, which will not be elaborated here.

[0077] Optionally, the aforementioned second ignition control command can be used to control the normal ignition of the engine. For example, a normal ignition command can be sent to the engine via the EMS to cause the engine to perform normal ignition operation.

[0078] Optionally, when the defrosting mode is a level-two defrosting mode, the VCU can generate the aforementioned second motor control command, second engine control command, and second ignition control command. Optionally, after generating the second motor control command, second engine control command, and second ignition control command, the second motor control command, second engine control command, and second ignition control command can be fused to obtain the second defrosting control command. For example, by using the VCU to write the aforementioned second motor control command, second engine control command, and second ignition control command into the same fused command set, a second fused command set can be obtained, and this second fused command set can be determined as the aforementioned second defrosting control command.

[0079] In this step, when the defrosting mode is the second-level defrosting mode, a second motor control command, a second engine control command, and a second ignition control command can be generated. Based on the second motor control command, the second engine control command, and the second ignition control command, a first defrosting control command can be obtained, thus providing the command basis for the vehicle to perform the defrosting operation.

[0080] As an optional embodiment, the method further includes: in response to switching the defrosting mode from a primary defrosting mode to a secondary defrosting mode, controlling the motor speed to switch from a first speed to a second speed according to a preset speed decrease rate; or, in response to switching the defrosting mode from a secondary defrosting mode to a primary defrosting mode, controlling the motor speed to switch from a second speed to a first speed according to a preset speed increase rate.

[0081] In this embodiment, the aforementioned speed decrease rate can be used to represent the slope of the motor's speed decrease. For example, the aforementioned speed decrease slope can be 150 rpm / s. Here, the speed decrease slope is only illustrative and is not specifically limited.

[0082] Optionally, the aforementioned speed increase rate can be used to represent the speed increase slope of the motor. For example, the speed increase slope can be 150 rpm / s. This speed increase slope is only illustrative and not specifically limited.

[0083] Optionally, in response to a switch from a first-level defrost mode to a second-level defrost mode, the motor speed can be smoothly switched from the first speed to the second speed according to a preset speed reduction rate. This effectively suppresses mechanical shock and noise vibration caused by sudden changes in motor speed, improving vehicle ride comfort and system stability during mode switching. For example, when the defrost mode switches from a first-level defrost mode to a second-level defrost mode, the motor speed can be controlled to decrease from 2000 rpm to 1200 rpm at a rate of 150 rpm / s.

[0084] Optionally, in response to a switch from a secondary defrost mode to a primary defrost mode, the motor speed can be smoothly switched from the secondary speed to the primary speed according to a preset speed increase rate. This effectively suppresses mechanical shock and noise vibration caused by sudden changes in motor speed, improving vehicle ride comfort and system stability during mode switching. For example, when the defrost mode switches from a secondary defrost mode to a primary defrost mode, the motor speed can be controlled to increase from 1200 rpm to 2000 rpm at a rate of 150 rpm / s.

[0085] In this step, when the defrosting mode switches between the first-level defrosting mode and the second-level defrosting mode, the motor speed can be controlled to switch between the first speed and the second speed according to the preset speed decrease rate or the preset speed increase rate. This achieves the goal of meeting the requirements of the motor in terms of noise, vibration and acoustic roughness, thereby improving the smoothness of the motor speed change.

[0086] As an optional embodiment, the method further includes: in response to a defrost exit command, controlling the vehicle to stop performing the defrost operation, and controlling the vehicle's engine to shut off after running in defrost mode for a preset time.

[0087] In this embodiment, the preset duration can be a pre-set continuous running time of the engine. For example, the preset duration can be 60 seconds. This preset duration is only for illustrative purposes and is not specifically limited.

[0088] Optionally, in response to a defrost exit command, the vehicle can be controlled to stop performing the defrost operation, and the vehicle's engine can be controlled to shut off after running in defrost mode for a preset time. For example, when a defrost exit command is received, the vehicle can be controlled to return to the state before the start of defrost mode, and the engine can be controlled to stop running after 60 seconds.

[0089] In this step, when a defrost exit command is received, the engine can be controlled to run continuously for a preset time and then shut off, thereby making full use of the engine's residual heat and improving the vehicle's defrosting effect.

[0090] As an optional embodiment, during the process of controlling the vehicle to perform a defrosting operation in defrosting mode, the method further includes: generating a prompt message based on the defrosting mode, wherein the prompt message is used to remind the driver of the vehicle's current defrosting mode; and sending the prompt message to the vehicle's display for display.

[0091] In this embodiment, the aforementioned prompt information can be used to remind the driver of the vehicle of the current defrosting mode. For example, the prompt information can be used to indicate that the current defrosting mode is either Level 1 or Level 2.

[0092] Optionally, the aforementioned display can be used to show the aforementioned prompt information. For example, the aforementioned display can be a screen in an in-vehicle infotainment (IVI) system in a vehicle.

[0093] Optionally, during the process of controlling the vehicle to perform the defrosting operation in the defrosting mode, a prompt message can be generated based on the defrosting mode. For example, when the defrosting mode is a level one defrosting mode, a prompt message indicating that the defrosting mode is a level one defrosting mode can be generated; when the defrosting mode is a level two defrosting mode, a prompt message indicating that the defrosting mode is a level two defrosting mode can be generated.

[0094] Optionally, after generating the prompt message, it can be sent to the vehicle's display for display. For example, the prompt message can be sent to the display screen in the IVI (In-Vehicle VI), which can use methods such as "bold font," "color change," and "icon flashing" to show the driver the vehicle's current defrosting mode.

[0095] In this embodiment, in response to a vehicle's defrost command, multi-dimensional state parameters of the vehicle are acquired; based on the multi-dimensional state parameters, the defrost mode to be entered by the vehicle is determined; a defrost control command in the defrost mode is generated; and in response to the defrost control command, the vehicle is controlled to perform a defrost operation in the defrost mode. In other words, in this embodiment, by acquiring the vehicle's multi-dimensional state parameters, the defrost mode to be entered by the vehicle can be determined, and based on the defrost mode, a defrost control command can be generated to control the vehicle to perform a defrost operation. That is, this application can determine the defrost mode to be entered by the vehicle based on the vehicle's multi-dimensional state parameters, thereby achieving the goal of adaptively adjusting the vehicle's defrost mode according to the defrost needs of vehicles in different regions. This solves the technical problem of low scene adaptability of the vehicle's defrost mode, and thus achieves the technical effect of improving the scene adaptability of the vehicle's defrost mode.

[0096] The technical solutions of the embodiments of this application will be illustrated below with reference to preferred embodiments.

[0097] To meet the needs of vehicles operating in cold regions, most vehicles are equipped with defrosting functions, which use the air conditioning system to blow hot air onto the vehicle's glass surfaces for rapid defrosting. In related technologies, vehicle defrosting control schemes typically employ a uniform defrosting mode. However, in some extremely cold regions, defrosting performance testing is more rigorous, and the requirements for defrosting effectiveness are higher. A uniform defrosting mode cannot simultaneously meet the diverse defrosting needs of different regions, resulting in a technical problem of poor scene adaptability of the vehicle's defrosting mode.

[0098] However, this application provides a vehicle defrosting operation method, which, in response to a vehicle defrosting command, acquires multi-dimensional state parameters of the vehicle; determines the defrosting mode to be entered based on the multi-dimensional state parameters; generates a defrosting control command in the defrosting mode; and, in response to the defrosting control command, controls the vehicle to perform a defrosting operation in the defrosting mode. In other words, in this embodiment, by acquiring the vehicle's multi-dimensional state parameters, the defrosting mode to be entered can be determined, and based on the defrosting mode, a defrosting control command can be generated to control the vehicle to perform a defrosting operation. That is, this application can determine the defrosting mode to be entered based on the vehicle's multi-dimensional state parameters, thereby achieving the goal of adaptively adjusting the vehicle's defrosting mode according to the defrosting needs of vehicles in different regions. This solves the technical problem of low scene adaptability of the vehicle's defrosting mode, and thus achieves the technical effect of improving the scene adaptability of the vehicle's defrosting mode.

[0099] Figure 2 This is a flowchart of a defrosting mode control method according to an embodiment of this application. Figure 2 As shown, the method may include the following steps.

[0100] Step S201: Receive defrost command.

[0101] In this embodiment, when the VCU receives a defrost command from the Air Conditioning Unit (AC), the VCU can enter defrost mode. At this time, step S202 can be executed.

[0102] Step S202: Determine whether the vehicle meets the conditions for the powerful defrosting mode.

[0103] In this embodiment, after the VCU enters defrost mode, it can obtain multi-dimensional status parameters of the vehicle by reading data from the vehicle's CAN bus. By comparing these multi-dimensional status parameters with the conditions for the intensive defrost mode, it can be determined whether the vehicle meets the conditions for the intensive defrost mode.

[0104] Optionally, the above-mentioned powerful defrosting mode conditions may include: the driver's side fan speed setting is greater than or equal to "level 7"; the passenger side fan speed setting is greater than or equal to "level 7"; the driver's side temperature setting is greater than or equal to "32℃"; the passenger side temperature setting is greater than or equal to "32℃"; the ambient temperature of the vehicle's current environment is less than "-14℃"; the vehicle's current gear is neutral or park; and the vehicle's air conditioning recirculation mode is internal recirculation mode.

[0105] Optionally, when the above multi-dimensional state parameters simultaneously meet the above-mentioned conditions for the powerful defrosting mode, the powerful defrosting mode is entered. At this time, step S203 can be executed.

[0106] Optionally, if the above-mentioned multi-dimensional state parameters do not simultaneously meet the conditions for the powerful defrosting mode, the system enters the normal defrosting mode. In this case, step S204 can be executed.

[0107] Step S203: Enter the powerful defrosting mode.

[0108] In this embodiment, the VCU controls the vehicle to enter a powerful defrosting mode.

[0109] Optionally, when entering the powerful defrosting mode, the VCU controls the vehicle motor to enter the speed mode, and controls the target speed of the motor to be 2000 rpm; the VCU controls the engine to be in the torque mode, and the target torque of the engine can be calculated by the above formula (1), which will not be repeated here; the VCU sends a delayed ignition command to the EMS to adjust the engine ignition advance angle; the VCU controls the working duty cycle of the electric water pump, and the working duty cycle of the electric water pump can be determined by querying Table 1 above, which will not be repeated here.

[0110] Optionally, Figure 3 This is a schematic diagram of a vehicle engine cooling system according to an embodiment of this application. Figure 3As shown, the coolant in the expansion tank, via the thermostat and mechanical water pump, enters the engine's engine cooler to cool the engine. After cooling the engine, a portion of the coolant flows back to the high-temperature radiator, is cooled by the radiator fan (ECF), and then flows back to the thermostat to continue cooling the engine. Simultaneously, another portion of the coolant flows via the electric water pump ECP3 to the vehicle's air conditioning system, providing heat to the front and rear heater air in the passenger compartment through electric valves ECV1, ECV2, and ECV3. In this embodiment, the VCU controls the duty cycle of the electric water pump ECP3 to ensure more coolant flows to the vehicle's air conditioning system, fully utilizing the heat generated by the engine to meet the heat requirements of the powerful defrost mode.

[0111] Step S204: Enter normal defrosting mode.

[0112] In this embodiment, the VCU controls the vehicle to enter the normal defrosting mode.

[0113] Optionally, when entering the normal defrost mode, the VCU controls the vehicle motor to enter the speed mode and controls the target speed of the motor to be 1200 rpm; the VCU controls the engine to be in the torque mode, and the target torque of the engine can be calculated by the above formula (1), which will not be repeated here; the VCU sends a normal ignition command to the EMS.

[0114] Step S205: Determine whether the vehicle has exited defrosting mode.

[0115] In this embodiment, the VCU can determine whether the vehicle has exited the defrost mode by receiving defrost commands from the AC in real time.

[0116] Optionally, when the defrost command indicates that the defrost mode should not be exited, the execution step S202 can be returned to determine whether the conditions for the powerful defrost mode are met.

[0117] Optionally, by determining whether the conditions for a powerful defrost mode are met, it can be determined whether the current defrost mode needs to be switched. If a switch is required, the VCU controls the motor speed to increase or decrease according to a preset speed change rate. For example, when switching from powerful defrost mode to normal defrost mode, the motor speed can be controlled to decrease from 2000 rpm to 1200 rpm at a rate of 150 rpm / s; when switching from normal defrost mode to powerful defrost mode, the motor speed can be controlled to increase from 1200 rpm to 2000 rpm at a rate of 150 rpm / s.

[0118] Optionally, when the defrost command indicates to exit the defrost mode, step S206 can be executed.

[0119] Step S206: Exit defrost mode.

[0120] In this embodiment, when exiting defrost mode, the VCU controls the engine to run continuously for 60 seconds before shutting it off. Simultaneously, the VCU first controls the motor speed to decrease, and then the AC controls the air conditioning system to reduce the fan speed to the value before entering defrost mode.

[0121] In steps S201 to S206 above, when the VCU receives a defrosting command, it can determine whether the vehicle enters a strong defrosting mode or a regular defrosting mode by comparing the multi-dimensional state parameters with the conditions of the strong defrosting mode. This achieves the purpose of meeting the different defrosting needs of the vehicle, thereby solving the technical problem of poor scene adaptability of the vehicle's defrosting mode, and thus realizing the technical effect of improving the applicability of the vehicle's defrosting mode.

Figure 4 As shown, the multiple controllers may include an air conditioning control unit 401, a vehicle control unit 402, a motor control unit 403, an engine control unit 404, and an in-vehicle entertainment and information system 405.

[0123] Optionally, the air conditioning control unit 401 can send signals such as driver's side airflow setting, passenger side airflow setting, driver's side temperature setting, passenger side temperature setting, air conditioning circulation mode, and defrost command to the vehicle control unit 402 through signal transmission path a.

[0124] Optionally, the vehicle control unit 402 can send signals such as motor operating mode, motor torque, and motor speed to the motor control unit 403 via signal transmission path b.

[0126] Optionally, the vehicle control unit 402 can send signals such as engine delayed ignition command and engine torque to the engine control unit 404 through signal transmission path d.

Figure 5As shown, the transmission 504 is mechanically connected to the drive motor 502, and the drive motor 502 is connected to the engine 503 via the CO clutch 501. When starting the vehicle from a stationary state, firstly, the CO clutch 501 is engaged, and the drive motor 502 drives the engine 503 to reach the speed threshold. Then, the CO clutch 501 disengages, and the VCU controls the engine to inject fuel and ignite, synchronizing the engine and the motor control unit. When the engine speed and the drive motor speed are synchronized, the VCU controls the CO clutch 501 to engage, at which point the vehicle starting is complete.
