Description

Technical Field

[0001] The present application relates to the field of vehicle control technology, and in particular to a control method and related equipment for requesting an AGS opening of an air-conditioning system. Background Art

[0002] For pure electric vehicles, in high-speed scenarios, the air-conditioning system's request for AGS opening control has always been a difficult problem. If the air-conditioning system requests AGS to open too large, the AGS with a larger opening will affect the vehicle's driving resistance, resulting in increased driving energy consumption at high speeds; if the air-conditioning system requests AGS to open too small, the AGS with a smaller opening may cause insufficient cooling of the air-conditioning system, thereby increasing the energy consumption of the air-conditioning system.

[0003] Therefore, it is necessary to propose a control method for requesting the AGS opening of an air conditioning system to solve the above problems. Summary of the invention

[0004] A series of simplified concepts are introduced in the Summary of the Invention section, which will be further described in detail in the Detailed Description of the Invention section. The Summary of the Invention section of this application does not mean to attempt to define the key features and essential technical features of the claimed technical solution, nor does it mean to attempt to determine the scope of protection of the claimed technical solution.

[0006] In a first aspect, the present application proposes a control method for requesting an AGS opening of an air conditioning system, comprising:

[0007] Acquire the current operating state of the compressor, wherein the operating state includes the compressor start state and the compressor working state;

[0008] When the compressor working state is a preset mode, a vehicle speed condition corresponding to the current vehicle speed is determined, so as to control the air conditioning system to request the AGS opening according to the vehicle speed condition; the vehicle speed condition includes a first vehicle speed condition and a second vehicle speed condition, and the vehicle speed and the vehicle speed duration in the first vehicle speed condition are both greater than the vehicle speed and the vehicle speed duration in the second vehicle speed condition;

[0009] If the current vehicle speed condition meets the first vehicle speed condition, different control modes are selected to control the opening degree of the AGS requested by the air-conditioning system according to the actual throttle circulation mode and the working state of the compressor.

[0010] In a feasible implementation manner, obtaining the current operating state of the compressor includes:

[0015] If the current control state is to select a different control mode according to the actual air door circulation mode and the working state of the compressor, when the current vehicle speed is less than or equal to 70 kph and the duration is greater than or equal to 10 seconds, the air conditioning system is controlled to request the AGS opening to be a second preset threshold;

[0016] If the current control state is to control the air-conditioning system to request the opening of AGS to be the second preset threshold, then when the current vehicle speed is greater than or equal to 80 kph and the duration is greater than or equal to 1 minute, different control modes are selected accordingly according to the actual throttle circulation mode and the working state of the compressor.

If P≤P21 and W≤W21, control the air-conditioning system to request the opening of AGS to be PWM2; if P≥P22 or W≥W22, control the air-conditioning system to request the opening of AGS to be the second preset threshold.

[0029] In a feasible implementation manner, when the actual damper circulation mode is internal circulation and the compressor working state is cooling mode, the air conditioning system requests the opening degree of the AGS by correspondingly selecting different control modes according to the actual damper circulation mode and the compressor working state, including:

[0030] According to the preset temperature thresholds T31, T32, and T33, the current ambient temperature T is divided into four ambient temperature levels according to T≤T31, T31<T≤T32, T32<T≤T33, and T>T33;

If P≤P31 and W≤W31, control the air-conditioning system to request the opening of AGS to be PWM3; if P≥P32 or W≥W32, control the air-conditioning system to request the opening of AGS to be the second preset threshold.

[0035] In a feasible implementation manner, when the actual damper circulation mode is external circulation and the compressor working state is cooling mode, the air conditioning system requests the opening degree of the AGS by correspondingly selecting different control modes according to the actual damper circulation mode and the compressor working state, including:

[0036] According to the preset temperature thresholds T41, T42, and T43, the current ambient temperature T is divided into four ambient temperature levels according to T≤T41, T41<T≤T42, T42<T≤T43, and T>T43;

[0057] In order to better understand the technical solutions provided by the embodiments of this specification, the technical solutions of the embodiments of this specification are described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiments of this specification and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this specification, rather than limitations on the technical solutions of this specification. In the absence of conflict, the embodiments of this specification and the technical features in the embodiments can be combined with each other.

[0058] In this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply that there is any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or equipment. In the absence of more restrictions, the elements limited by the statement "comprise one..." do not exclude the existence of other identical elements in the process, method, article or equipment including the elements. The term "more than two" includes two or more than two situations.

[0059] The present application provides a control method for the AGS opening degree requested by the air-conditioning system, which controls the AGS opening degree requested by the air-conditioning system according to whether the electric vehicle compressor is turned on, the compressor working status, the vehicle speed, the actual damper circulation mode, the ambient temperature, the high-pressure side pressure of the air-conditioning system, and the compressor power, thereby ensuring that the AGS opening degree requested by the air-conditioning system is reduced as much as possible without increasing the energy consumption of the air-conditioning system, thereby reducing the driving energy consumption at high speed and obtaining positive benefits.

[0060] See also Figure 1 , is a flow chart of a control method for requesting AGS opening of an air conditioning system provided in an embodiment of the present application, which may specifically include:

[0061] S110. Obtain the current operating state of the compressor, where the operating state includes a compressor start state and a compressor working state.

[0062] For example, by judging whether the compressor is turned on, the basic operating status of the air-conditioning system can be determined, and the AGS opening can be preliminarily controlled. Furthermore, the compressor working status includes self-heating mode, heat pump mode or cooling mode. After determining that the compressor is turned on, judging its working status helps to understand the operating requirements of the air-conditioning system more accurately. Different operating modes may require different air flow, temperature adjustment, etc., and the opening adjustment of the AGS may affect these requirements.

[0063] S120. When the compressor working state is in a preset mode, determine the vehicle speed condition corresponding to the current vehicle speed, so as to control the air-conditioning system to request the opening degree of the AGS according to the vehicle speed condition; the vehicle speed condition includes a first vehicle speed condition and a second vehicle speed condition, and the vehicle speed and vehicle speed duration in the first vehicle speed condition are both greater than the vehicle speed and vehicle speed duration in the second vehicle speed condition.

[0064] Exemplarily, when the compressor working state is a preset mode, the air-conditioning system enters the vehicle speed condition judgment requesting AGS opening control, and two control states correspond to two vehicle speed conditions.

[0065] S130: If the current vehicle speed condition satisfies the first vehicle speed condition, a different control mode is selected to control the opening degree of the AGS requested by the air-conditioning system according to the actual air door circulation mode and the working state of the compressor.

[0066] Exemplarily, the control mode to be entered is determined according to the actual damper mode and the working state of the compressor. If the actual damper mode is the internal circulation and the working state of the compressor is the control mode of the heat pump mode, if the actual damper mode is the external circulation and the working state of the compressor is the control mode of the heat pump mode, if the actual damper mode is the internal circulation and the working state of the compressor is the control mode of the cooling mode, if the actual damper mode is the external circulation and the working state of the compressor is the control mode of the cooling mode.

[0067] In some examples, obtaining the current operating status of the compressor includes:

[0068] Determine the compressor startup state; if the compressor is started, determine the compressor working state; if the compressor is not started, control the air conditioning system to request the AGS opening to be a first preset threshold;

[0069] If the compressor is in the self-heating mode, the air-conditioning system is controlled to request the AGS opening to be the first preset threshold.

[0070] For example, if the compressor is not turned on, it means that the air conditioning system may be in a non-operating state or in a state that does not require AGS (which may be some equipment related to the air conditioning system) to participate in regulation. When the compressor is not turned on, the air conditioning system is directly controlled to request the opening of AGS to be the first preset threshold (the first preset threshold is set to 0 in this embodiment), avoiding unnecessary energy consumption or system conflicts, and ensuring that the system is in a stable, low-energy consumption state when the compressor is not working.

[0071] If the compressor is in self-heating mode, the air conditioning system is controlled to request the AGS opening to be 0. This is because the self-heating mode may not require the introduction of external air or require a specific air circulation method, so setting the AGS opening to 0 can meet the system requirements in this mode. If the compressor is in heat pump mode or cooling mode, it enters the next judgment condition to provide a basis for subsequent more complex control logic, so as to determine the appropriate AGS opening according to more specific conditions.

[0072] In some examples, when the compressor working state is a preset mode, determining whether the current vehicle speed meets a target vehicle speed condition, so as to control the air conditioning system to request the opening degree of the AGS according to the target vehicle speed condition, includes:

[0073] If the compressor is in heat pump mode or cooling mode, determine the vehicle speed condition corresponding to the current vehicle speed; wherein the first vehicle speed condition is that the current vehicle speed is greater than or equal to 80 kph and the duration is greater than or equal to 1 minute; the second vehicle speed condition is that the current vehicle speed is less than or equal to 70 kph and the duration is greater than or equal to 10 seconds;

[0074] If the current control state is to select a different control mode according to the actual air door circulation mode and the working state of the compressor, when the current vehicle speed is less than or equal to 70 kph and the duration is greater than or equal to 10 seconds, the air conditioning system is controlled to request the AGS opening to be a second preset threshold;

[0075] If the current control state is to control the air-conditioning system to request the opening of AGS to be the second preset threshold, then when the current vehicle speed is greater than or equal to 80 kph and the duration is greater than or equal to 1 minute, different control modes are selected accordingly according to the actual throttle circulation mode and the working state of the compressor.

[0076] Exemplarily, there are two control states according to different vehicle speed conditions. Control state 1 is to control the air conditioning system to request the opening of AGS to be the second preset threshold (in this embodiment, the second preset threshold is set to the fully open state). Control state 2 indicates the need to enter the next judgment condition. When the air conditioning system is in control state 1, that is, the air conditioning system requests the opening of AGS to be fully open. If you want to enter control state 2 at this time, you need to meet the condition that the vehicle speed is ≥ 80kph (kilometers per hour), and the state of vehicle speed ≥ 80kph must last for 1 minute. Only when the vehicle speed condition and the duration condition are met at the same time, will it change from control state 1 to control state 2 and enter the next judgment process. When the air conditioning system is in control state 2, if you want to return to control state 1, that is, let the air conditioning system request the opening of AGS to be fully open again, you need to meet the condition that the vehicle speed is ≤ 70kph, and the state of vehicle speed ≤ 70kph must last for 10 seconds. Only when both conditions are met will it change from control state 2 to control state 1.

[0077] In some examples, when the actual damper circulation mode is internal circulation and the compressor working state is heat pump mode, the air conditioning system requests the opening degree of the AGS by correspondingly selecting different control modes according to the actual damper circulation mode and the compressor working state, including:

[0078] According to the preset temperature thresholds T11, T12, and T13, the current ambient temperature T is divided into four ambient temperature levels according to T≤T11, T11<T≤T12, T12<T≤T13, and T>T13;

[0079] According to the current ambient temperature T, determine the current ambient temperature level;

[0080] Performing a live test on each of the ambient temperature levels, when the air conditioning system requests the AGS to be fully open, obtaining the high-pressure side pressure thresholds P11 and P12 and the compressor power thresholds W11 and W12;

[0081] Performing a real-time test on each of the ambient temperature levels to obtain the minimum opening value PWM1 of the cooling demand of the current air-conditioning system;

[0082] Obtain the high-pressure side pressure P and compressor power W of the current air-conditioning system. If P≤P11 and W≤W11, control the air-conditioning system to request the opening of AGS to be PWM1; if P≥P12 or W≥W12, control the air-conditioning system to request the opening of AGS to be the second preset threshold.

[0083] Exemplarily, the ambient temperature is divided into four ambient temperature levels according to T≤T11, T11<T≤T12, T12<T≤T13, and T>T13. The ambient temperature is divided into four levels according to different temperature ranges. T11, T12, and T13 are pre-set temperature thresholds. When the ambient temperature T meets different conditions, it will be divided into the corresponding ambient temperature level.

[0084] Use the current actual ambient temperature value to determine which of the four ambient temperature levels it belongs to.

[0085] By conducting actual tests at each ambient temperature level, when the variable grille system (AGS) is in full open state, observe the high-pressure side pressure after the air conditioning system reaches a stable state and the working condition of the compressor. Based on these test results, four parameter values ​​are determined at the current ambient temperature level, namely P11, P12, W11, and W12. Among them, P11 and P12 may represent the high-pressure side pressure thresholds under different circumstances, and W11 and W12 may represent the compressor power thresholds under different circumstances.

[0086] Similarly, through actual tests at each ambient temperature level, the AGS opening value PWM1 is determined. This opening is the minimum opening that can meet the cooling demand of the air conditioning system at the current ambient temperature level.

[0087] The next control action is determined based on the current high-pressure side pressure P and compressor power W of the air-conditioning system. If the high-pressure side pressure P is less than or equal to P11 and the compressor power W is less than or equal to W11, the air-conditioning system is controlled to request the AGS to open at PWM1; if the high-pressure side pressure P is greater than or equal to P12 or the compressor power W is greater than or equal to W12, the air-conditioning system is controlled to request the AGS to open at full. In this way, the opening of the AGS can be dynamically adjusted according to different pressure and power conditions to meet the operating requirements of the air-conditioning system.

[0088] In some examples, when the actual damper circulation mode is external circulation and the compressor working state is heat pump mode, the air conditioning system requests the opening degree of the AGS by selecting different control modes according to the actual damper circulation mode and the compressor working state, including:

[0089] According to the preset temperature thresholds T21, T22, and T23, the current ambient temperature T is divided into four ambient temperature levels according to T≤T21, T21<T≤T22, T22<T≤T23, and T>T23;

[0090] According to the current ambient temperature T, determine the current ambient temperature level;

[0091] Performing a live test on each of the ambient temperature levels, when the air conditioning system requests the AGS to be fully open, obtaining the high-pressure side pressure thresholds P21, P22 and the compressor power thresholds W21, W22;

[0092] Performing a real-time test on each of the ambient temperature levels to obtain the minimum opening value PWM2 of the cooling demand of the current air-conditioning system;

[0093] Obtain the high-pressure side pressure P and compressor power W of the current air-conditioning system. If P≤P21 and W≤W21, control the air-conditioning system to request the opening of AGS to be PWM2; if P≥P22 or W≥W22, control the air-conditioning system to request the opening of AGS to be the second preset threshold.

[0094] Exemplarily, the ambient temperature is divided into four ambient temperature levels according to T≤T21, T21<T≤T22, T22<T≤T23, and T>T23. The ambient temperature is divided into four levels according to different temperature ranges. T21, T22, and T23 are pre-set temperature thresholds. When the ambient temperature T meets different conditions, it will be divided into the corresponding ambient temperature level.

[0095] Use the current actual ambient temperature value to determine which of the four ambient temperature levels it belongs to.

[0096] By conducting actual tests at each ambient temperature level, when the variable grille system (AGS) is in full open state, observe the high-pressure side pressure after the air conditioning system reaches a stable state and the working condition of the compressor. Based on these test results, four parameter values ​​are determined at the current ambient temperature level, namely P21, P22, W21, and W22. Among them, P21 and P22 may represent the high-pressure side pressure thresholds under different conditions, and W21 and W22 may represent the compressor power thresholds under different conditions.

[0097] Similarly, through actual tests at each ambient temperature level, the AGS opening value PWM2 is determined. This opening is the minimum opening that can meet the cooling demand of the air conditioning system at the current ambient temperature level.

[0098] The next control action is determined based on the current high-pressure side pressure P and compressor power W of the air-conditioning system. If the high-pressure side pressure P is less than or equal to P21 and the compressor power W is less than or equal to W21, the air-conditioning system is controlled to request the AGS to open at PWM2; if the high-pressure side pressure P is greater than or equal to P22 or the compressor power W is greater than or equal to W22, the air-conditioning system is controlled to request the AGS to open at full. In this way, the opening of the AGS can be dynamically adjusted according to different pressure and power conditions to meet the operating requirements of the air-conditioning system.

[0099] In some examples, when the actual damper circulation mode is internal circulation and the compressor working state is cooling mode, the air conditioning system requests the opening degree of the AGS by selecting different control modes according to the actual damper circulation mode and the compressor working state, including:

[0100] According to the preset temperature thresholds T31, T32, and T33, the current ambient temperature T is divided into four ambient temperature levels according to T≤T31, T31<T≤T32, T32<T≤T33, and T>T33;

[0101] According to the current ambient temperature T, determine the current ambient temperature level;

[0102] Performing a live test on each of the ambient temperature levels, when the air conditioning system requests the AGS to be fully open, obtaining the high-pressure side pressure thresholds P31 and P32 and the compressor power thresholds W31 and W32;

[0103] Performing a real-time test on each of the ambient temperature levels to obtain the minimum opening value PWM3 of the cooling demand of the current air-conditioning system;

[0104] Obtain the high-pressure side pressure P and compressor power W of the current air-conditioning system. If P≤P31 and W≤W31, control the air-conditioning system to request the opening of AGS to be PWM3; if P≥P32 or W≥W32, control the air-conditioning system to request the opening of AGS to be the second preset threshold.

[0105] Exemplarily, the ambient temperature is divided into four ambient temperature levels according to T≤T31, T31<T≤T32, T32<T≤T33, and T>T33. The ambient temperature is divided into four levels according to different temperature ranges. T31, T32, and T33 are pre-set temperature thresholds. When the ambient temperature T meets different conditions, it will be divided into the corresponding ambient temperature level.

[0106] Use the current actual ambient temperature value to determine which of the four ambient temperature levels it belongs to.

[0107] By conducting actual tests at each ambient temperature level, when the variable grille system (AGS) is in full open state, observe the high-pressure side pressure after the air conditioning system reaches a stable state and the working condition of the compressor. Based on these test results, four parameter values ​​are determined at the current ambient temperature level, namely P31, P32, W31, and W32. Among them, P31 and P32 may represent the high-pressure side pressure thresholds under different conditions, and W31 and W32 may represent the compressor power thresholds under different conditions.

[0108] Similarly, through actual tests at each ambient temperature level, the AGS opening value PWM3 is determined. This opening is the minimum opening that can meet the cooling demand of the air conditioning system at the current ambient temperature level.

[0109] The next control action is determined based on the current high-pressure side pressure P and compressor power W of the air-conditioning system. If the high-pressure side pressure P is less than or equal to P31 and the compressor power W is less than or equal to W31, the air-conditioning system is controlled to request the AGS to open at PWM3; if the high-pressure side pressure P is greater than or equal to P32 or the compressor power W is greater than or equal to W32, the air-conditioning system is controlled to request the AGS to open at full. In this way, the opening of the AGS can be dynamically adjusted according to different pressure and power conditions to meet the operating requirements of the air-conditioning system.

[0110] In some examples, when the actual damper circulation mode is external circulation and the compressor working state is cooling mode, the air conditioning system requests the opening degree of the AGS by correspondingly selecting different control modes according to the actual damper circulation mode and the compressor working state, including:

[0111] According to the preset temperature thresholds T41, T42, and T43, the current ambient temperature T is divided into four ambient temperature levels according to T≤T41, T41<T≤T42, T42<T≤T43, and T>T43;

[0112] According to the current ambient temperature T, determine the current ambient temperature level;

[0113] Performing a live test on each of the ambient temperature levels, when the air conditioning system requests the AGS to be fully open, obtaining the high-pressure side pressure thresholds P41 and P42 and the compressor power thresholds W41 and W42;

[0114] Performing a real-time test on each of the ambient temperature levels to obtain the minimum opening value PWM4 of the cooling demand of the current air-conditioning system;

[0115] Obtain the high-pressure side pressure P and compressor power W of the current air-conditioning system. If P≤P41 and W≤W41, control the air-conditioning system to request the opening of AGS to be PWM4; if P≥P42 or W≥W42, control the air-conditioning system to request the opening of AGS to be the second preset threshold.

[0116] Exemplarily, the ambient temperature is divided into four ambient temperature levels according to T≤T41, T41<T≤T42, T42<T≤T43, and T>T43. The ambient temperature is divided into four levels according to different temperature ranges. T41, T42, and T43 are pre-set temperature thresholds. When the ambient temperature T meets different conditions, it will be divided into the corresponding ambient temperature level.

[0117] Use the current actual ambient temperature value to determine which of the four ambient temperature levels it belongs to.

[0118] By conducting actual tests at each ambient temperature level, when the variable air intake grille system (AGS) is in full open state, observe the high-pressure side pressure after the air conditioning system reaches a stable state and the working condition of the compressor. Based on these test results, four parameter values ​​are determined at the current ambient temperature level, namely P41, P42, W41, and W42. Among them, P41 and P42 may represent the high-pressure side pressure thresholds under different conditions, and W41 and W42 may represent the compressor power thresholds under different conditions.

[0119] Similarly, through actual tests at each ambient temperature level, the AGS opening value PWM4 is determined. This opening is the minimum opening that can meet the cooling demand of the air conditioning system at the current ambient temperature level.

[0120] The next control action is determined based on the current high-pressure side pressure P and compressor power W of the air-conditioning system. If the high-pressure side pressure P is less than or equal to P41 and the compressor power W is less than or equal to W41, the air-conditioning system is controlled to request the AGS to open at PWM4; if the high-pressure side pressure P is greater than or equal to P42 or the compressor power W is greater than or equal to W42, the air-conditioning system is controlled to request the AGS to open at full. In this way, the opening of the AGS can be dynamically adjusted according to different pressure and power conditions to meet the operating requirements of the air-conditioning system.

[0121] In summary, the present application provides a control method for the AGS opening requested by the air-conditioning system, which controls the AGS opening requested by the air-conditioning system according to whether the electric vehicle compressor is turned on, the compressor working status, the vehicle speed, the actual damper circulation mode, the ambient temperature, the high-pressure side pressure of the air-conditioning system, and the compressor power, thereby ensuring that the AGS opening requested by the air-conditioning system is reduced as much as possible without increasing the energy consumption of the air-conditioning system, thereby reducing the driving energy consumption at high speed and obtaining positive benefits.
