[0002] Active Grille System (AGS) is a new fuel-saving technology in recent years. It has the characteristics of relatively low cost and obvious fuel-saving effect. It has been widely used in the European and North American vehicle markets. It reasonably controls the opening of the front grille during driving to adjust the cooling air volume entering the engine compartment, reduce the internal circulation resistance during driving, and improve the fuel economy of the whole vehicle.

[0055] Figure 3 It is a structural block diagram of a compressor protection device provided by an embodiment of the present invention. DETAILED DESCRIPTION

[0056] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0057] Reference Figure 1 , shows a flowchart of a compressor protection method provided by an embodiment of the present invention, and the method may specifically include the following steps:

[0058] Step 101 : obtaining a start-up mode of the air conditioning system of the vehicle and an opening degree of the air intake grille system of the vehicle, and performing fault detection on the air intake grille system.

[0059] The air intake grille is an important part of the front shape of the vehicle, affecting the design style of the whole vehicle. It is also the entrance for air to flow into the vehicle's engine compartment. At present, the air intake grilles on most vehicles are fixed structures, while the Active Grille System (AGS) is a device that measures the engine water temperature, oil temperature, air conditioning system status, intake air temperature and other information, and relies on the control motor to open or close the shutters of the air intake grille to a certain angle. After the vehicle is equipped with AGS, the vehicle's air conditioning system requires front-end air intake to maintain system pressure. If the AGS fails, it is easy to cause damage to the compressor. In addition, when the pressure of the air conditioning system is too high, the strategy of directly disconnecting the compressor will be adopted, which will give users a very bad driving experience.

[0060] Different startup modes of the vehicle's air-conditioning system have different impacts on the air intake grille system, so the startup mode of the vehicle's air-conditioning system can be obtained. The startup mode can be the mode of the air-conditioning system started by the user according to demand, such as cooling mode or heating mode. Under different startup modes, the vehicle's air intake grille system is tested for faults, and the opening of the vehicle's air intake grille system can also be obtained. The opening of the air intake grille system can be the angle at which the louvers of the air intake grille are opened. When there is no fault in the air intake grille system, when the user starts the cooling mode of the air-conditioning system, the compressor can be started, or the air-conditioning system can be started in heating mode according to the user's operation.

[0061] In the embodiment of the present invention, when the controller is installed on the air intake grille, the controller can perform self-test to detect the air intake grille system, determine whether there is a fault in the air intake grille system, and obtain the opening of the air intake grille system.

[0062] Step 102: If the mode is a cooling mode and there is a fault in the air intake grid system, then detecting whether the opening degree belongs to a preset first opening degree range.

[0063] If the start-up mode of the vehicle's air conditioning system is the cooling mode, and the detection result of the air intake grille system is that there is a fault, the opening of the air intake grille system is judged to determine whether the opening of the air intake grille system belongs to a preset first opening range, for example, the first opening range can be [5%, 10%]. When the start-up mode is the cooling mode, if there is a fault in the air intake grille system, it can be determined whether the opening of the air intake grille system is in [5%, 10%]. The specific first opening range can be set according to actual conditions, and the embodiment of the present invention is not limited to this.

[0064] Step 103: If the opening degree satisfies the first opening degree range, starting the compressor is prohibited.

[0065] When the vehicle's air-conditioning system's startup mode is the cooling mode and there is a fault in the air intake grille system, if the opening of the air intake grille system satisfies the first opening range, the controller can prohibit the startup of the compressor. This is because the air intake grille system has already failed and the current opening of the air intake grille system can no longer meet the normal operation of the compressor. Therefore, there is no need to start the compressor again before the fault in the air intake grille system is eliminated. Starting the compressor will instead cause damage to the compressor again.

[0066] In an embodiment of the present invention, if the opening degree satisfies the first opening degree range, prohibiting starting the compressor includes:

[0067] obtaining a requested power of the compressor;

[0068] Determining the execution power of the compressor according to the requested power and a preset proportional threshold;

[0069] Acquire the relief pressure of the compressor and the pressure of the air-conditioning system after the compressor is executed with the execution power;

[0070] detecting whether the pressure reaches the pressure relief pressure;

[0071] If so, starting of the compressor is prohibited.

[0072] When the opening of the air intake grille system satisfies the first opening range, the controller can obtain the requested power of the compressor, wherein the requested power can be the power required for the operation of the compressor. However, the current opening of the air intake grille system is relatively small. If power is sent to the compressor according to the requested power, the pressure of the air-conditioning system will increase, causing the compressor to be directly disconnected. If the compressor is directly disconnected when the pressure is relatively high, it will give the user a very abrupt feeling and reduce the user's driving experience. Therefore, a proportional threshold can be preset, and the proportional threshold can be 80%. The execution power of the compressor can be determined based on the requested power of the compressor and the preset proportional threshold, so that the compressor can work according to the execution power and reduce the pressure of the air-conditioning system. Then, the pressure relief pressure of the compressor and the pressure of the air-conditioning system after the compressor uses the execution power to execute are obtained, and then the pressure of the air-conditioning system is judged to detect whether the pressure of the air-conditioning system reaches the pressure relief pressure of the compressor. If the pressure of the air-conditioning system reaches the pressure relief pressure of the compressor, the compressor can be prohibited from starting. In this way, the pressure of the air-conditioning system is reduced first, and then the compressor is disconnected, which can reduce the user's sense of impact and improve the user's driving experience.

[0073] In the embodiment of the present invention, determining the execution power of the compressor according to the requested power and a preset proportional threshold value includes:

[0074] The product of the requested power and the ratio threshold is calculated to obtain the execution power.

[0075] After obtaining the requested power of the compressor, the product of the requested power and the proportional threshold value may be calculated to obtain the execution power of the compressor, so that the compressor can work according to the execution power to reduce the pressure of the air-conditioning system.

[0076] In an embodiment of the present invention, the method further includes:

[0077] If the pressure does not reach the pressure relief pressure, the opening is repeatedly detected to see whether it belongs to a preset first opening range, and when the pressure reaches the pressure relief pressure, starting the compressor is prohibited.

[0078] After judging the pressure of the air-conditioning system, if the pressure of the air-conditioning system does not reach the pressure relief pressure of the compressor, repeat the step of detecting whether the opening of the air intake grille system belongs to the preset first opening range, and slowly reduce the pressure of the air-conditioning system until the pressure of the air-conditioning system reaches the pressure relief pressure of the compressor. Then, the compressor can be prohibited from starting. In this way, the compressor can be disconnected after reducing the pressure of the air-conditioning system many times, which can provide users with a cache process and improve the user's driving experience.

[0079] In an embodiment of the present invention, the method further includes:

[0080] If the opening does not satisfy the first opening range, detecting whether the opening belongs to a preset third opening range;

[0081] If the opening degree satisfies the third opening degree range, starting the compressor is prohibited.

[0082] When the vehicle's air conditioning system is started in cooling mode and there is a fault in the air intake grille system, if the opening of the air intake grille system does not meet the first opening interval, it is possible to detect whether the opening of the air intake grille system belongs to the preset third opening interval. If the opening of the air intake grille system meets the third opening interval, the opening of the air intake grille system is very small and insufficient for the normal operation of the compressor. Therefore, it is necessary to prohibit the compressor from starting to protect the compressor. If the opening of the air intake grille system does not meet the third opening interval, the opening of the air intake grille system is greater than the first opening interval. The maximum value, so the opening of the air intake grid system is relatively large, the compressor can operate normally, so the compressor can be started normally. For example, the first opening interval can be [5%, 10%], and the third opening interval can be an opening [0%, 5%). If the opening of the air intake grid system does not meet the first opening interval or the third opening interval, the opening of the air intake grid system is (10%, 100%), so the opening of the air intake grid system is greater than the maximum value of the first opening interval. The specific third opening interval can be set according to actual conditions, and the embodiment of the present invention is not limited to this.

[0083] Step 104: If the mode is the heating mode and there is a fault in the air intake grille system, then detecting whether the opening degree belongs to a preset second opening degree range.

[0084] If the start-up mode of the vehicle's air conditioning system is the heating mode, and the detection result of the air intake grille system is that there is a fault, the opening of the air intake grille system is judged to determine whether the opening of the air intake grille system belongs to a preset second opening range, for example, the second opening range can be [50%, 100%]. When the start-up mode is the heating mode, if there is a fault in the air intake grille system, it can be determined whether the opening of the air intake grille system is in [50%, 100%]. The specific second opening range can be set according to actual conditions, and the embodiment of the present invention is not limited to this.

[0085] Step 105: If the opening degree satisfies the second opening degree range, prohibiting the air conditioning system from starting the heating mode.

[0086] When the activation mode of the air conditioning system of the vehicle is the heating mode and there is a fault in the air intake grille system, if the opening degree of the air intake grille system satisfies the second opening degree range, the air conditioning system may be prohibited from activating the heating mode.

[0087] In the embodiment of the present invention, if the opening degree satisfies the second opening degree range, prohibiting the air conditioning system from starting the heating mode includes:

[0088] Acquiring the ambient temperature of the vehicle;

[0089] Detecting whether the ambient temperature belongs to a preset temperature range;

[0090] If the ambient temperature meets the temperature range, the air conditioning system is prohibited from starting the heating mode.

[0091] When the opening of the air intake grille system meets the second opening interval, the controller can obtain the ambient temperature of the vehicle, and then detect whether the ambient temperature belongs to the preset temperature interval. If the ambient temperature meets the temperature interval, the start of the air conditioning system can be prohibited. For example, the temperature interval can be [-∞, 0°], and the second opening interval can be [50%, 100%]. Because the air intake grille system has a fault, the current opening of the air intake grille system is too large, and the ambient temperature is too low. If the air conditioning system is started, there will be a risk of frost on the compressor. Therefore, before the air intake grille system eliminates the fault, the air conditioning system cannot be started in heating mode. If the heating mode is started, it may cause the compressor to frost and cause damage to the compressor. If the ambient temperature does not meet the temperature interval, there will be no risk of frost on the compressor. When the opening of the air intake grille system meets the second opening interval and the ambient temperature does not belong to the temperature interval, the compressor can operate normally and there will be no risk of frost. Therefore, the air conditioning system can be started in heating mode according to the user's operation.

[0092] The start-up mode of the vehicle's air conditioning system and the opening of the vehicle's air intake grille system are obtained, and the air intake grille system is detected for faults; if the mode is a cooling mode and there is a fault in the air intake grille system, whether the opening belongs to a preset first opening interval is detected; if the opening satisfies the first opening interval, the requested power of the compressor is obtained; the execution power of the compressor is determined according to the requested power and the preset proportional threshold; the pressure relief pressure of the compressor is obtained, and the pressure of the air conditioning system after the compressor uses the execution power to complete the execution; whether the pressure reaches the pressure relief pressure; if so, the compressor is prohibited from starting; if the mode is a heating mode and there is a fault in the air intake grille system, whether the opening belongs to a preset second opening interval is detected; if the opening satisfies the second opening interval, the ambient temperature of the vehicle is obtained; whether the ambient temperature belongs to a preset temperature interval is detected; if the ambient temperature satisfies the temperature interval, the air conditioning system is prohibited from starting the heating mode. In the embodiment of the present invention, when the air conditioning system is in the cooling mode, the requested power of the compressor can be adjusted to reduce the pressure of the air conditioning system, and then the pressure of the air conditioning system is judged to determine whether it is necessary to prohibit the compressor from starting. It is also possible to judge the ambient temperature when the air-conditioning system is in heating mode to determine whether it is necessary to prohibit the air-conditioning system from starting the heating mode based on user operations, so as to solve the problem that when a fault in the air intake grille system is detected, the compressor will only be disconnected if the pressure of the air-conditioning system is too high, causing damage to the compressor. In addition, the pressure of the air-conditioning system can be reduced so that the user will not feel abrupt when the compressor is prohibited from starting.

[0093] In order to enable those skilled in the art to better understand the embodiments of the present invention, Figure 3 A flowchart of the steps of another compressor protection method provided by an embodiment of the present invention is shown.

[0094] After the vehicle is started, if the user starts the air-conditioning system, the startup mode of the air-conditioning system can be obtained, including cooling mode or heating mode. If the air-conditioning system starts the cooling mode, the controller on the AGS performs a self-check to obtain the detection result of the AGS, determine whether there is a fault in the AGS, and obtain the opening degree of the AGS.

[0095] If there is a fault in the AGS, it is determined whether the opening of the AGS belongs to the first opening interval. If it belongs to the first opening interval, the requested power of the compressor is obtained, and the product of the requested power and the proportional threshold is calculated to obtain the execution power of the compressor, so that the compressor can work according to the execution power, and the pressure relief pressure of the compressor and the pressure of the air-conditioning system after the compressor works according to the execution power are obtained. It is determined whether the pressure of the air-conditioning system reaches the pressure relief pressure of the compressor. If it reaches it, the controller prohibits the compressor from starting. If it does not reach it, the step of determining whether the opening of the AGS belongs to the first opening interval is repeated. If there is no fault in the AGS, the process ends and the compressor is started.

[0096] If the opening of the AGS belongs to the first opening range, it is determined whether the opening of the AGS belongs to the third opening range. If it belongs to the third opening range, the controller prohibits the compressor from starting. If it does not belong to the third opening range, the process is terminated and the compressor is started.

[0097] If the air conditioning system starts the heating mode, the controller on the AGS performs a self-check to obtain the detection result of the AGS, determine whether the AGS has a fault, and obtain the opening degree of the AGS.

[0098] If the AGS is faulty, it is determined whether the opening of the AGS belongs to the second opening range. If it belongs to the second opening range, the ambient temperature of the vehicle is obtained to determine whether the ambient temperature belongs to the temperature range. If the opening of the AGS does not belong to the second opening range, the process is terminated and the air conditioning system starts the heating mode. If the ambient temperature belongs to the temperature range, the controller prohibits the air conditioning system from starting the heating mode. If the ambient temperature does not belong to the temperature range, the process is terminated and the air conditioning system starts the heating mode.
