[0026] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application.

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0027] Overview

[0028] As described in the background technology, a large number of sensors are provided in the thermal management air conditioning system. The thermal management air conditioning system controls the normal operation of each component in the system based on the data detected by the sensors to meet user needs. If a sensor fails, such as signal loss, it may be impossible to control the normal operation of each component in the system, causing the compressor in the system to shut down, resulting in abnormal cooling and reduced indoor comfort.

[0029] On this basis, the inventors have found through further research that after determining that the first sensor, i.e., any of the multiple sensors provided in the thermal management air conditioning system, is faulty, the thermal management air conditioning system is controlled to work according to the first fault handling method or the second fault handling method based on the attribute information of the first sensor and the current working mode of the thermal management air conditioning system, that is, based on the replacement data of the detection data of the first sensor and the detection data of the second sensor, the thermal management air conditioning system is controlled to continue working in the current working mode, or based on the detection data of the second sensor, the thermal management air conditioning system is controlled to work in the target working mode. In this way, when a sensor fails, the thermal management air conditioning system can be controlled to work based on the replacement data of the detection data of the sensor, or the thermal management air conditioning system can be controlled to continue working in other working modes, thereby avoiding the shutdown of the compressor in the system and ensuring the cooling effect.

[0030] Based on the above concept, an embodiment of the present specification provides a sensor fault processing method, which will be exemplarily described below in conjunction with the accompanying drawings.

[0031] Example scenarios

[0032] refer to Figure 1 , Figure 1 Schematic diagram of a feasible application scenario of the sensor fault handling method, namely a thermal management air-conditioning system.

[0033] like Figure 1 As shown, the thermal management air conditioning system includes a compressor 110 , a condenser 120 , a first electronic expansion valve 130 , namely EXV1 , and an evaporator 140 .

[0034] When the cab needs to be cooled, the first electronic expansion valve 130 is opened, and the compressor 110 sucks in the low-temperature and low-pressure gaseous refrigerant, i.e., the refrigerant, and compresses it into a high-pressure and high-temperature gaseous refrigerant, which is sent to the condenser 120 along the pipeline. The compressor 110 drives the refrigerant to circulate in the system to provide power for the refrigeration cycle. The condenser 120 dissipates the high-temperature and high-pressure refrigerant vapor discharged from the compressor 110 into the atmosphere through the radiator 450, condensing it into liquid refrigerant. The liquid refrigerant continues to pass through the first electronic expansion valve 130 along the pipeline to the evaporator 140. The evaporator 140 converts the low-temperature and low-pressure liquid refrigerant into a low-temperature and low-pressure gaseous refrigerant to provide a cooling effect for the cab. The gaseous refrigerant continues to return to the compressor 110 along the pipeline, and the cycle is repeated in this way to reduce the temperature of the cab.

[0035] like Figure 1 As shown, the thermal management air conditioning system further includes a second electronic expansion valve 210, namely EXV2, a heat exchanger 220 and a second water pump 230, namely Pu2.

[0036] When the battery needs to be cooled, the second electronic expansion valve 210 is opened, and when the refrigerant flows through the heat exchanger 220, it exchanges heat with the cooling water in the heat exchanger 220. At the same time, the second water pump 230 is turned on to circulate water to reduce the battery temperature.

[0037] like Figure 1 As shown, the thermal management air conditioning system further includes a PTC heater 310 , a heating module 320 , a first water pump 330 , namely Pu1 , and a first water tank 340 .

[0038] The heating module 320 and the evaporator 140 are arranged in the air conditioning box.

[0039] When the cab needs to be heated, the water temperature is adjusted by adjusting the power of the PTC heater 310 to increase the water temperature. At the same time, the first water pump 330 is turned on for water circulation, so that the water in the first water tank 340 flows through the first water pump 330 and the PTC heater 310 to the heating module 320. The heating module 320 uses the cooling circulating water as a heat source and transfers the heat energy to the cab through the air-conditioning system to heat the cab.

[0040] like Figure 1 As shown, the thermal management air conditioning system also includes a second water tank 240 .

[0041] When the battery needs to be heated, the second electronic expansion valve 210 is disconnected. When the refrigerant flows through the heat exchanger 220, it does not exchange heat with the cooling water in the heat exchanger 220. The second water pump 230 is turned on for water circulation, so that the water in the second water tank 240 flows through the second water pump 230 to the battery box assembly 250, and then returns to the second water tank 240. This cycle is repeated to heat the battery evenly.

[0042] like Figure 1 As shown, the thermal management air conditioning system further includes a motor group 410 , a third water tank 420 , a third water pump 430 , namely Pu3 , a controller 440 , and a radiator 450 arranged in parallel with the third water tank 420 .

[0043] The motor group 410 includes a chassis drive motor, a top motor and a top motor driver, and the controller 440 can be an all-in-one controller.

[0044] As the heat generated by the motor group 410 and the controller 440 increases with the increase in working time, the fan 460 on the radiator 450 inhales air and accelerates its flow, so that the coolant flowing through the radiator 450 is cooled more quickly, thereby reducing the temperature of the third water tank 420. The third water pump 430 is turned on to promote the circulation of cooling water to reduce the temperature of the cooling water in the entire pipeline. This cycle is repeated to achieve heat dissipation for the motor group 410 and the controller 440. At the same time, the fan 460 is used to dissipate heat for the condenser 120.

[0045] It is understandable that the operating modes of the thermal management air-conditioning system include single cab cooling mode, single battery cooling mode, cab and battery dual cooling mode, cab heating and battery cooling mode, cooling and demisting mode, heating and demisting mode, etc.

[0046] Specifically, the flow direction of the refrigerant or cooling water in each pipeline of the thermal management air conditioning system can be as follows: Figure 1 As shown by the arrows.

[0047] The thermal management air conditioning system also includes a cab temperature sensor (i.e., an in-vehicle temperature sensor, Figure 1 Not shown), battery cell temperature sensor ( Figure 1 ), heat exchanger outlet temperature sensor 510, namely T2, evaporator outlet temperature sensor 520, namely T4, evaporator surface temperature sensor 530, namely T3, low pressure PT sensor 540, namely PT, compressor outlet (exhaust) temperature sensor 550, namely T1, condenser outlet pressure sensor 560, namely P H , the battery water inlet temperature sensor 570 , namely T5, and the battery water outlet temperature sensor 580 , namely T6.

[0048] The low-pressure PT sensor 540 can measure the low-pressure of the refrigerant at its location, and there is a corresponding relationship between the low-pressure and the evaporation saturation temperature of the refrigerant.

[0049] Exemplary Methods

[0050] See also Figure 2 In an exemplary embodiment, a sensor fault processing method is provided, which is applied to Figure 1 In the thermal management air conditioning system shown, a plurality of sensors are arranged in the thermal management air conditioning system, including an evaporator outlet temperature sensor, a heat exchanger outlet temperature sensor, a low-pressure PT sensor, a battery water inlet temperature sensor, a battery water outlet temperature sensor, an in-vehicle temperature sensor, and an evaporator surface temperature sensor.

[0051] like Figure 2 As shown, the sensor fault processing method includes steps S201-S202:

[0052] S201: Determine whether the first sensor is faulty.

[0053] The first sensor is any one of the multiple sensors.

[0054] When the first sensor is in working state, if the signal of the first sensor is not received within a preset time length, the first sensor is determined to be faulty. Alternatively, whether the first sensor is faulty can also be determined based on other methods, such as whether the value of the detection data of the first sensor exceeds a preset value range.

[0055] S202: Based on the attribute information of the first sensor and the current operation mode of the thermal management air conditioning system, control the thermal management air conditioning system to operate according to the first fault handling method or the second fault handling method.

[0056] Among them, the current working modes are single battery cooling, single cab cooling, or battery and cab dual cooling.

[0057] The first fault handling method is to control the thermal management air conditioning system to continue to work in the current working mode based on the replacement data of the detection data of the first sensor and the detection data of the second sensor. The second fault handling method is to control the thermal management air conditioning system to work in the target working mode based on the detection data of the second sensor.

[0058] The target working mode is single cab cooling or single battery cooling, and the second sensor is a sensor other than the first sensor among the multiple sensors.

[0059] The replacement data of the detection data of the first sensor is obtained by correcting the detection data of the associated sensor of the first sensor, where the associated sensor is a sensor in the second sensor associated with the first sensor, and the associated sensor is in working state in the current working mode.

[0060] Based on the attribute information of the first sensor and the current working mode of the thermal management air conditioning system, the first fault processing mode or the second fault processing mode is determined as the target fault processing mode, and the thermal management air conditioning system is controlled to work according to the target fault processing mode.

[0061] The attribute information of the first sensor includes information items such as the identification, location, and sensor type of the first sensor, wherein the sensor type is a temperature sensor and / or a pressure sensor.

[0062] In this embodiment, after determining that the first sensor, i.e., any one of the multiple sensors provided in the thermal management air conditioning system, is faulty, the thermal management air conditioning system is controlled to work according to the first fault handling method or the second fault handling method based on the attribute information of the first sensor and the current working mode of the thermal management air conditioning system, that is, the thermal management air conditioning system is controlled to continue working in the current working mode based on the replacement data of the detection data of the first sensor and the detection data of the second sensor, or the thermal management air conditioning system is controlled to work in the target working mode based on the detection data of the second sensor. In this way, when a sensor fails, the thermal management air conditioning system can be controlled to work based on the replacement data of the detection data of the sensor, or the thermal management air conditioning system can be controlled to continue working in other working modes, so as to avoid the compressor in the system from shutting down and ensure the cooling effect.

[0063] In some embodiments, based on the attribute information of the first sensor and the current working mode of the thermal management air conditioning system, the thermal management air conditioning system is controlled to work according to the first fault handling method or the second fault handling method.

[0064] If the first sensor is an evaporator outlet temperature sensor or a heat exchanger outlet temperature sensor, and the current working mode is single cooling, that is, single cab cooling or single battery cooling, the thermal management air conditioning is controlled to work according to the first fault handling method.

[0065] Since the first sensor is in working condition in the current working mode, when the evaporator outlet temperature sensor is in working condition, the current working mode is single cab cooling or battery and cab dual cooling; similarly, when the heat exchanger outlet temperature sensor is in working condition, the current working mode is single battery cooling or battery and cab dual cooling.

[0066] Specifically, if the first sensor is the evaporator outlet temperature sensor and the current working mode is single cab cooling, the thermal management air conditioning system is controlled to operate according to the first fault handling method; if the first sensor is the evaporator outlet temperature sensor and the current working mode is dual cooling of battery and cab, the thermal management air conditioning system is controlled to operate according to the second fault handling method.

[0067] Similarly, if the first sensor is a heat exchanger outlet temperature sensor and the current operating mode is single battery cooling, the thermal management air conditioning system is controlled to operate in accordance with the first fault handling method; if the first sensor is a heat exchanger outlet temperature sensor and the current operating mode is dual cooling of the battery and the cab, the thermal management air conditioning system is controlled to operate in accordance with the second fault handling method.

[0068] Since the first sensor is in working state under the current working mode, when the battery water inlet temperature sensor is in working state, the current working mode can be single battery cooling or battery and cab dual cooling; when the evaporator surface temperature sensor and the in-vehicle temperature sensor are in working state, the current working mode can be single cab cooling or battery and cab dual cooling.

[0069] Specifically, if the first sensor is a battery water inlet temperature sensor, an in-vehicle temperature sensor, or an evaporator surface temperature sensor, the thermal management air conditioning system is controlled to operate according to the first fault handling method.

[0070] It is understandable that since the first fault handling method is different from the second fault handling method, the first fault handling method controls the operation of the thermal management air-conditioning system based on the replacement data of the detection data of the first sensor. Therefore, only when the first sensor fails and there is a corresponding replacement sensor in the current working mode, the first fault handling method can be selected to control the operation of the thermal management air-conditioning system. When there is no corresponding replacement sensor, the second fault handling method can be selected to control the operation of the thermal management air-conditioning system. In this way, the thermal management air-conditioning system can be controlled to continue to work when the first sensor fails, thereby avoiding the thermal management air-conditioning system from failing to work due to sensor failure and avoiding compressor shutdown, thereby ensuring the cooling effect.

[0071] Therefore, when determining the fault handling method, it is possible to first determine whether there is an associated sensor of the first sensor in the second sensor based on the attribute information of the first sensor and the current working mode. If so, it is determined to control the thermal management air-conditioning system to operate according to the first fault handling method; if not, it is determined to control the thermal management air-conditioning system to operate according to the second fault handling method.

[0072] The associated sensor of the first sensor is a sensor in the second sensor associated with the first sensor, and the associated sensor is in a working state in the current working mode.

[0073] Specifically, when determining whether there is an associated sensor of the first sensor in the second sensor, the sensors in the second sensor that are in working state in the current working mode can be first selected as the selected sensors based on the current working mode. Then, based on the correlation between the selected sensors and the first sensor, it is determined that there is a sensor in the selected sensors whose correlation exceeds a preset correlation threshold, and it is determined that there is an associated sensor of the first sensor in the second sensor; conversely, if there is no sensor in the selected sensors whose correlation exceeds the preset correlation threshold, it is determined that there is no associated sensor of the first sensor in the second sensor.

[0074] Exemplarily, the correlation between the candidate sensor and the first sensor can be determined based on the correlation between the detection data of the two, such as the volatility of the difference. Generally, the greater the volatility of the difference between the detection data of the two, the weaker the correlation between the detection data of the two, and the smaller the correlation between the two.

[0075] In this embodiment, based on the attribute information of the first sensor and in combination with the current working mode, when the first sensor is an evaporator outlet temperature sensor or a heat exchanger outlet temperature sensor and the current working mode is a single cooling mode, the thermal management air-conditioning system is controlled to work in accordance with the first fault handling method and in combination with the detection data of the second sensor and the replacement data of the detection data of the first sensor. When the first sensor is an evaporator outlet temperature sensor or a heat exchanger outlet temperature sensor and the current working mode is a dual cooling mode, the thermal management air-conditioning system is controlled to work in a single cooling mode. When the first sensor is a battery water inlet temperature sensor, an in-vehicle temperature sensor or an evaporator surface temperature, the thermal management air-conditioning system is controlled to still work in the current working mode. Thus, in different working modes and sensor faults, the corresponding fault handling method is adopted. By determining the replacement data and changing the working mode, the thermal management air-conditioning system is controlled to work, which can effectively realize sensor fault handling, avoid losses caused by direct shutdown of the compressor, and ensure the cooling effect.

[0076] In some embodiments, when the first sensor is an evaporator outlet temperature sensor and the associated sensor is a low-pressure PT sensor, the thermal management air conditioning system is controlled to operate according to the first fault handling method. That is, the evaporation saturation temperature data corresponding to the detection data of the low-pressure PT sensor is corrected to obtain replacement data of the detection data of the evaporator outlet temperature sensor, and then, based on the replacement data and the detection data of the second sensor, the thermal management air conditioning system is controlled to continue to operate in the single cab cooling mode.

[0077] Among them, there is a corresponding relationship between the detection data of the low-pressure PT sensor, that is, the low-pressure pressure of the refrigerant and the evaporation saturation temperature of the refrigerant, and the corresponding relationship can be stored in the form of a table. Therefore, the evaporation saturation temperature data corresponding to the detection data of the low-pressure PT sensor can be obtained by looking up the table based on the detection data of the low-pressure PT sensor.

[0078] In the single cab cooling working mode, the temperature difference between the evaporation saturation temperature data corresponding to the detection data of the low-pressure PT sensor and the temperature data detected by the evaporator outlet temperature sensor is small, and the fluctuation rate of the difference is small. For example, the difference is 0.1°C.

[0079] Therefore, the detection data of the low-pressure PT sensor corresponding to the evaporation saturation temperature data can be corrected based on the first preset correction value to obtain replacement data of the detection data of the evaporator outlet temperature sensor. The first preset correction value can be, for example, 0.1°C, which can be determined based on actual working conditions.

[0080] The thermal management air conditioning system continues to operate in the single cab cooling mode without shutting down.

[0081] Alternatively, based on different actual needs, the evaporation saturation temperature corresponding to the detection data of the low-pressure PT sensor can be directly used as replacement data for the detection data of the evaporator outlet temperature sensor.

[0082] In this embodiment, the first sensor is the evaporator outlet temperature sensor. In the single cab refrigeration working mode, the evaporation saturation temperature corresponding to the detection data of the low-pressure PT sensor is corrected to obtain accurate replacement data close to the detection data of the evaporator outlet temperature sensor.

[0083] Afterwards, based on the replacement data and the detection data of the second sensor, the thermal management air-conditioning system can be more accurately controlled to continue working in the single cab cooling mode, effectively avoiding losses caused by downtime due to sensor failure and ensuring the cooling effect.

[0084] In some embodiments, when the first sensor is a heat exchanger outlet temperature sensor, the associated sensor is a low-pressure PT sensor, and the thermal management air conditioning system is controlled to operate according to the first fault handling method. That is, the evaporation saturation temperature data corresponding to the detection data of the low-pressure PT sensor is corrected to obtain replacement data of the detection data of the heat exchanger outlet temperature sensor, and then, based on the replacement data and the detection data of the second sensor, the thermal management air conditioning system is controlled to continue to operate in the single-battery cooling mode.

[0085] In the single-cell cooling mode, the temperature difference between the evaporation saturation temperature data corresponding to the detection data of the low-pressure PT sensor and the temperature data detected by the heat exchanger outlet temperature sensor is small, and the fluctuation rate of the difference is small. Therefore, the evaporation saturation temperature data corresponding to the detection data of the low-pressure PT sensor can be corrected based on the difference to obtain accurate replacement data of the detection data of the heat exchanger outlet temperature sensor.

[0086] Specifically, a second preset correction value is determined based on the difference, and based on the second preset correction value, the evaporation saturation temperature data corresponding to the detection data of the low-pressure PT sensor is corrected to obtain replacement data of the detection data of the heat exchanger outlet temperature sensor.

[0087] The second preset correction value may be, for example, 0.1° C., which may be determined based on actual working conditions.

[0088] Alternatively, based on different actual needs, the evaporation saturation temperature corresponding to the detection data of the low-pressure PT sensor can be directly used as replacement data for the detection data of the heat exchanger outlet temperature sensor.

[0089] In this embodiment, the first sensor is the heat exchanger outlet temperature sensor. In the single-battery refrigeration working mode, the evaporation saturation temperature corresponding to the detection data of the low-pressure PT sensor is corrected to obtain accurate replacement data close to the detection data of the heat exchanger outlet temperature sensor. Afterwards, based on the replacement data and the detection data of the second sensor, the thermal management air-conditioning system can be more accurately controlled to continue working in the single-battery refrigeration mode, effectively avoiding losses caused by shutdown due to sensor failure and ensuring the refrigeration effect.

[0090] In some embodiments, when the first sensor is a battery water inlet temperature sensor, the associated sensor is a battery water outlet temperature sensor, and the thermal management air conditioning system is controlled to work according to the first fault handling method. That is, the detection data of the battery water outlet temperature sensor is corrected to obtain replacement data of the detection data of the battery water inlet temperature sensor, and then, based on the replacement data and the detection data of the second sensor, the thermal management air conditioning system is controlled to continue working in the current working mode.

[0091] Specifically, the detection data of the battery water outlet temperature sensor, i.e., the battery water outlet temperature data, is corrected based on the third preset correction value to obtain replacement data of the battery water inlet temperature data, i.e., replacement data of the detection temperature of the battery water inlet temperature sensor.

[0092] The difference between the battery outlet water temperature and the battery inlet water temperature under normal operation is 4° C. The third preset correction value can be determined based on the difference. Exemplarily, the third preset correction value is 4° C.

[0093] More specifically, the difference between the battery water outlet temperature data and the third preset correction value is used as replacement data for the detection temperature of the battery water inlet temperature sensor.

[0094] In this embodiment, the first sensor is a battery water inlet temperature sensor. The detection data of the battery water outlet temperature sensor is corrected to obtain accurate replacement data close to the detection data of the battery water inlet temperature sensor. Afterwards, based on the replacement data and the detection data of the second sensor, the thermal management air-conditioning system can be more accurately controlled to continue working in the current working mode, effectively avoiding losses caused by shutdown due to sensor failure and ensuring the cooling effect.

[0095] In some embodiments, when the first sensor is a battery water outlet temperature sensor, the associated sensor is a battery water inlet temperature sensor, and the thermal management air conditioning system is controlled to operate according to the first fault handling method. That is, the detection data of the battery water inlet temperature sensor is corrected to obtain replacement data of the detection data of the battery water outlet temperature sensor, and based on the replacement data and the detection data of the second sensor, the thermal management air conditioning system is controlled to continue to operate in the current operating mode.

[0096] Specifically, based on the fourth preset correction value, the detection data of the battery water inlet temperature is corrected to obtain replacement data of the detection data of the battery water outlet temperature sensor.

[0097] The difference between the battery water outlet temperature and the battery water inlet temperature under normal operation is 4°C, and the battery water outlet temperature is higher than the battery water inlet temperature. The third preset correction value can be determined based on the difference. Exemplarily, the third preset correction value is 4°C.

[0098] More specifically, the sum of the battery water inlet temperature data and the third preset correction value is used as replacement data for the detection temperature of the battery water outlet temperature sensor.

[0099] In this embodiment, the first sensor is a battery water outlet temperature sensor. The detection data of the battery water inlet temperature sensor is corrected to obtain accurate replacement data close to the detection data of the battery water outlet temperature sensor. Afterwards, based on the replacement data and the detection data of the second sensor, the thermal management air-conditioning system can be more accurately controlled to continue working in the current working mode, effectively avoiding losses caused by shutdown due to sensor failure and ensuring the cooling effect.

[0100] In some embodiments, the first sensor includes a battery water inlet temperature sensor and a battery water outlet temperature sensor.

[0101] After determining that the battery water inlet temperature sensor is faulty, the detection data of the battery water outlet temperature sensor is corrected to obtain replacement data of the detection data of the battery water inlet temperature sensor, and based on the replacement data and the detection data of the second sensor, the thermal management air-conditioning system is controlled to operate. Afterwards, if the battery water outlet temperature sensor is faulty, the battery refrigeration is controlled to be shut down.

[0102] In this way, on the basis of the failure of the battery water inlet temperature sensor, the battery water outlet temperature sensor, which serves as a substitute sensor for the battery water inlet temperature sensor, also fails. When the battery refrigeration cannot operate normally, the battery refrigeration is turned off, thereby maximally ensuring the normal operation of the battery refrigeration, avoiding losses caused by sensor failure, and ensuring the cooling effect.

[0103] In some embodiments, when the first sensor is an in-vehicle sensor, the associated sensor is an evaporator surface temperature sensor, and the thermal management air conditioning system is controlled to operate according to the first fault handling method. That is, the detection data of the evaporator surface temperature sensor is corrected to obtain replacement data of the detection data of the in-vehicle sensor, and then, based on the replacement data and the detection data of the second sensor, the thermal management air conditioning system is controlled to continue to operate in the current operating mode.

[0104] Generally, the evaporator surface temperature is lower than the vehicle interior temperature. A fifth preset correction value can be determined based on the difference between the two values, and based on the fifth preset correction value, the detection data of the evaporator surface temperature sensor is corrected to obtain accurate replacement data of the detection data of the vehicle interior sensor.

[0105] In this way, the detection data of the evaporator surface temperature sensor is corrected to obtain replacement data of the detection data of the in-vehicle sensor. Afterwards, based on the replacement data and the detection data of the second sensor, the thermal management air-conditioning system is controlled to continue working in the current working mode, which can avoid losses caused by refrigeration suspension and control the refrigeration of the thermal management air-conditioning system with a greater cooling force to ensure the cooling effect.

[0106] In some embodiments, when the first sensor is an evaporator surface temperature sensor and the associated sensor is a low-pressure PT sensor, the thermal management air conditioning system is controlled to operate according to the first fault handling method, that is, the evaporation saturation temperature data corresponding to the detection data of the low-pressure PT sensor is corrected to obtain replacement data of the detection temperature of the evaporator surface temperature sensor, and then, based on the replacement data and the detection data of the second sensor, the thermal management air conditioning system is controlled to continue to operate in the current working mode.

[0107] In this way, when the evaporator surface temperature fails, the first fault handling method can also be used to accurately determine the replacement data of the detection data of the evaporator surface temperature sensor, and then based on the replacement data and the data of the second sensor, control the thermal management air-conditioning system to continue working in the current working mode, effectively avoiding losses caused by shutdown due to sensor failure and ensuring the cooling effect.

[0108] In some embodiments, when the first sensor is an evaporator outlet temperature sensor and the current working mode is a battery and cab dual cooling mode, the thermal management air conditioning system is controlled to work according to the second fault handling method, including:

[0109] Based on the detection data of the second sensor, the thermal management air conditioning system is controlled to operate in a target operating mode.

[0110] Specifically, based on the attribute information of the first sensor and the current working mode, the target working mode is first determined, and then based on the detection data of the second sensor, the thermal management air-conditioning system is controlled to work in the target working mode.

[0111] Among them, the first sensor is the evaporator outlet temperature sensor, and the current working mode is the dual cooling mode of battery and cab, then the target working mode is determined to be single battery cooling, and in accordance with the second fault handling method, based on the detection data of the second sensor, the thermal management air-conditioning system is controlled to work in the single battery cooling mode, and the thermal management air-conditioning system is controlled to work.

[0112] In this embodiment, when the first sensor is a sensor that is in working state when the cab is cooled alone, that is, the evaporator outlet temperature sensor, the cab cooling is turned off, and the target working mode is determined to be single-battery cooling. Based on the detection data of the second sensor, the thermal manager air-conditioning system is controlled to work in the single-battery cooling mode, thereby realizing the switching from dual cooling to single cooling, avoiding the use of faulty detection data or inferred detection data, ensuring the cooling effect in the single cooling mode, and avoiding losses caused by downtime.

[0113] In some embodiments, when the first sensor is a heat exchanger outlet temperature sensor and the current working mode is a battery and cab dual cooling mode, the thermal management air conditioning system is controlled to work according to the second fault handling method, including:

[0114] Based on the detection data of the second sensor, the thermal management air conditioning system is controlled to operate in a target operating mode.

[0115] Specifically, based on the attribute information of the first sensor and the current working mode, the target working mode is first determined, and then based on the detection data of the second sensor, the thermal management air-conditioning system is controlled to work in the target working mode.

[0116] Among them, the first sensor is the heat exchanger outlet temperature sensor, and the current working mode is the dual cooling mode of battery and cab, then the target working mode is determined to be single cab cooling, and in accordance with the second fault handling method, based on the detection data of the second sensor, the thermal management air-conditioning system is controlled to work in the single cab cooling mode, and the thermal management air-conditioning system is controlled to work.

[0117] In this way, when the first sensor is the sensor in working state when single battery cooling is used, that is, the heat exchanger outlet temperature sensor, the battery cooling is turned off, and the target working mode is determined to be single cab cooling. Then, based on the detection data of the second sensor, the thermal manager air-conditioning system is controlled to work in the single cab cooling working mode, thereby realizing the switching from dual cooling to single cooling, avoiding the use of faulty detection data or inferred detection data, ensuring the cooling effect in the single cooling mode, and avoiding losses caused by downtime.

[0118] In some embodiments, when the current working mode is dual cooling of the battery and the cab, and the first sensor is a low-pressure PT sensor, the associated sensors may be an evaporator outlet temperature sensor and a heat exchanger outlet temperature sensor. The average of the detection data of the evaporator outlet temperature sensor and the detection data of the heat exchanger outlet temperature sensor is used as the low-pressure pressure data corresponding to the replacement data of the detection data of the low-pressure PT sensor, and based on the low-pressure pressure data and the detection data of the second sensor, the thermal management air-conditioning system is controlled to operate, thereby avoiding losses caused by direct shutdown and ensuring the cooling effect.

[0119] For example, the process of sensor fault processing can be as follows: Figure 3 As shown, there are five cases:

[0120] Case 1: When the evaporator outlet temperature sensor in the cab fails,

[0121] When the current cooling mode is single cab cooling, the evaporation saturation temperature data corresponding to the detection data of the low-pressure PT sensor is used to replace the detection data of the evaporator outlet temperature sensor, and the single cab cooling is continued, that is, the low-pressure PT sensor is used instead, and the logic calculation is continued without stopping;

[0122] When the current cooling mode is dual cooling of the battery and the cab, the cab cooling is turned off and the battery is still cooled normally, that is, the battery cooling is normal, thereby realizing arbitrary switching between single cooling and dual cooling.

[0123] Case 2: When the solar panel outlet temperature sensor (i.e. the heat exchanger outlet temperature sensor mentioned above) fails,

[0124] When the current cooling mode is single-battery cooling, the low-pressure PT sensor (the temperature data corresponding to the detection data) is used instead, and the logic calculation continues, that is, the single-battery cooling continues without stopping;

[0125] When the current cooling mode is dual cooling of battery and cab, the battery cooling is turned off and the cab cooling is normal, thus realizing arbitrary switching between single cooling and dual cooling.

[0126] Case 3: When the battery water inlet temperature sensor fails, use (T 出 -4℃) instead of the battery water inlet temperature, where T 出 Characterizes the battery water outlet temperature, 4°C is the temperature difference between the battery inlet and outlet water in the water cooling system under normal operation. At this time, if the battery water outlet temperature sensor fails, the battery cooling is turned off. It is understandable that when the battery inlet water temperature sensor fails, the detection data of the battery water outlet temperature sensor and the inlet and outlet water temperature difference can be smoothly switched to replace the detection data of the battery inlet water temperature sensor without stopping the machine.

[0127] Case 4: When the in-car temperature sensor fails, the evaporator surface temperature control method is used to control the cab cooling, that is, the evaporator surface temperature is used instead of the in-car temperature, and the logic calculation is continued without stopping. The evaporator surface temperature is lower than the in-car temperature, but it does not affect the working mode of the thermal management air conditioning system, but the cooling effect is stronger.

[0128] Case 5: When the evaporator surface temperature sensor fails, the low-pressure PT sensor is used to replace the evaporator surface temperature sensor, and the logic calculation continues without stopping. Generally, the low-pressure pressure detected by the low-pressure PT sensor corresponds to the evaporation saturation temperature which is slightly lower than the evaporator surface temperature, and the temperature difference between the two is generally about 5°C.
