Description

Technical Field

[0002] In the thermal management system functions of existing electric vehicle models, when the air conditioner cools, heats, cools and heats the battery, it needs to consume the electric energy of the whole vehicle to work, and the proportion of the electric energy consumed by the system has a great impact on the electric consumption of the whole vehicle and the cruising range. In some cases, such as when the window is not closed tightly, the internal and external circulation ratio is incorrect, the refrigerant leaks, the sensor fails, the air door seal is poor, etc., generally, it will not affect the customer's use function and performance, but these situations will cause the load of the thermal management system to increase, resulting in an increase in system energy consumption, and then affecting the increase in the energy consumption of the whole vehicle, the actual cruising range of the user decreases, and the user's charging cost increases. For example, when the refrigerant of a user's vehicle leaks, the electric compressor needs to work at a higher rotational speed to maintain the refrigeration performance, resulting in a relatively high power consumption of the compressor. In this case, the user does not feel a decrease in the refrigeration performance and does not feel the problem, but actually due to the increase in the power consumption of the compressor, the user's cruising range is reduced and the charging cost is also increased.

[0045] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

Optionally, the memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0048] Those skilled in the art can understand that Figure 1 the structure shown in

[0049] does not constitute a limitation on the fault diagnosis device, and may include more or fewer components than shown in the figure, or combine some components, or different component arrangements. Figure 1 shown, the memory 1005, as a storage medium, may include an operating system, a network communication module, a user interface module, and a fault diagnosis program.

[0050] In Figure 1 the fault diagnosis device shown, the network interface 1004 is mainly used for data communication with a network server; the user interface 1003 is mainly used for data interaction with a user; the processor 1001 and the memory 1005 in the fault diagnosis device of the present invention can be arranged in the fault diagnosis device, and the fault diagnosis device calls the fault diagnosis program stored in the memory 1005 through the processor 1001 and executes the fault diagnosis method provided by the embodiments of the present invention.

[0051] Based on the above fault diagnosis device, an embodiment of the present invention provides a fault diagnosis method. Referring to Figure 2 , Figure 2 it is a schematic flowchart of the first embodiment of the fault diagnosis method of the present invention.

[0052] In this embodiment, the fault diagnosis method includes the following steps:

[0053] Step S10: Collect the actual power of the power-consuming component to be detected during vehicle driving.

[0054] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication, and program running functions, such as a mobile phone, a tablet computer, a personal computer, an on-board computer, etc., or an electronic device or a fault diagnosis device capable of implementing the above functions. Hereinafter, the fault diagnosis device will be taken as an example to illustrate this embodiment and the following embodiments.

[0055] It should be noted that the power-consuming component to be detected can be a power-consuming component related to vehicle thermal management, such as components like a compressor, an electric fan, a blower, a water pump, a damper motor, etc. The actual power of the power-consuming component to be detected can be the power actually generated by the power-consuming component to be detected during use.

[0056] Step S20: Obtain the target power range corresponding to the power-consuming component to be detected.

[0057] It should be noted that the target power range can be the normal power range corresponding to each power-consuming component to be detected under different road conditions, different seasons, temperatures, wind speeds, etc. obtained through road tests and environmental tests.

[0058] Step S30: Compare the actual power with the target power range to obtain a comparison result.

[0059] It should be noted that comparing the actual power with the target power range can be to determine whether the actual power corresponding to each power-consuming component to be detected is within the target power range corresponding to the power-consuming component to be detected.

[0060] Step S40: Determine the fault diagnosis result according to the comparison result.

[0061] It should be noted that if the actual power of a power-consuming component to be detected is not within its corresponding target power range, it can be indicated that there is a fault in the power-consuming component to be detected. At this time, the power-consuming component to be detected may be able to meet the user's needs. However, if the actual power of the power-consuming component to be detected is higher than the upper limit value in its corresponding target power range, it may cause the user to consume more electrical energy when using the power-consuming component to be detected, resulting in a decrease in the vehicle's endurance and an increase in the user's charging cost, reducing the user's experience. The step of determining the fault diagnosis result according to the comparison result includes: determining the target power-consuming component whose actual power is not within the target power range according to the comparison result; collecting the component power of the target power-consuming component; when the component power is not within the target power range, determining that the target power-consuming component has a fault.

[0062] It should be noted that the component power of the target power-consuming component may be the actual power of the target power-consuming component collected subsequently.

[0063] In a specific implementation, after determining the target power-consuming component whose actual power is not within the target power range according to the comparison result, the component power of the target power-consuming component is collected at a preset collection frequency. If the component power of the target power-consuming component is still not within the target power range after a preset number of collections, it is determined that the target power-consuming component has a fault. Among them, the preset collection frequency and the preset number are self-defined values according to the actual situation and can be adjusted appropriately. This embodiment does not limit them here.

[0064] Further, in order to improve the processing speed and efficiency after a fault occurs, after step S40, it further includes: determining the fault type according to the fault diagnosis result; when the fault type is a hardware fault, determining the fault details corresponding to the current fault in the fault diagnosis result; sending the fault details to the target terminal; when the fault type is a user operation fault, prompting the user to correct the current fault corresponding to the fault diagnosis result.

[0065] It should be noted that the failure types are divided into user operation failures and hardware failures. The user operation failures can be those caused by improper user operations such as the user not closing the window tightly or incorrect internal and external circulation ratios. The hardware failures can be component failures such as refrigerant leakage, sensor failures, poor air damper seals, compressors, electric fans, blowers, water pumps, and air damper motors. The failure details can include the failed components, fault codes, and detailed information about the failures. The target terminal can be the terminal corresponding to the after-sales department of the vehicle or the mobile terminal of the vehicle owner. Prompting the user to correct the current failure corresponding to the fault diagnosis result can be to display the failure details on the user terminal or the in-vehicle large screen and prompt the user to correct the failure, or to prompt the user to correct the user operation failure in the form of voice broadcast.

[0066] In this embodiment, the actual power of the power-consuming component to be detected during vehicle driving is collected; the target power range corresponding to the power-consuming component to be detected is obtained; the actual power is compared with the target power range to obtain a comparison result; and the fault diagnosis result is determined according to the comparison result. Since in this embodiment, the actual power of the power-consuming component to be detected during vehicle driving is obtained; the actual power is compared with the target power range corresponding to the power-consuming component to be detected to obtain a comparison result; and the fault diagnosis result is determined according to the comparison result. Compared with the existing method of still operating the power-consuming component according to the actual power when the actual power of the power-consuming component is not within the target power range, the above method in this embodiment can detect the faults of the power-consuming components in advance, reduce the energy consumption of the vehicle, and increase the cruising range.

[0067] Reference Figure 3 , Figure 3 is a schematic flowchart of the second embodiment of the fault diagnosis method of the present invention.

[0068] Based on the above first embodiment, in this embodiment, the step S20 includes:

[0069] Step S201: Obtain the test result of the vehicle's environmental simulation test.

[0070] It should be noted that the environmental simulation test can include a road test and an environmental test. The road test can be a test conducted by the vehicle on an actual road, and the environmental test can be a vehicle driving test in which the vehicle is made to travel under different temperatures, different wind speeds, etc. During the test, information such as solar radiation, human body heat, body heat dissipation, and other heat in the vehicle is collected through temperature sensors, human infrared temperature sensors, vehicle speed sensors, etc. arranged in the vehicle to generate a test result.

[0071] Step S202: Determine the target total power range according to the test result.

[0072] It should be noted that determining the target total power range according to the test results may be to determine the vehicle's overall target energy consumption based on the overall vehicle thermal performance load target in the test results, and determine the target total power range according to the vehicle's overall target energy consumption.

[0073] Further, in order to obtain a more accurate target total power range and thus accurately determine whether there is an energy consumption fault in the power-consuming components to be detected in the vehicle, step S202 may include: determining the heat information corresponding to the vehicle and the target correction coefficient according to the test results; determining the target thermal performance load of the vehicle according to the heat information; and determining the target total power range according to the target thermal performance load and the target correction coefficient.

[0074] It should be noted that the heat information may include solar radiation heat, human heat, body heat dissipation, and other heat sources. The target correction coefficient may be a percentage correction coefficient, which includes an upper limit value and a lower limit value, and can be obtained through empirical calibration or adjusted according to the current environmental adaptability. This embodiment does not limit it here. Determining the target thermal performance load of the vehicle according to the heat information may be to add up the various heats in the heat information to obtain the target thermal performance load. Determining the target total power range according to the target thermal performance load and the target correction coefficient may be to multiply the target thermal performance load by the lower limit value in the target correction coefficient to obtain the lower limit value in the target energy consumption range, multiply the target thermal performance load by the upper limit value in the target correction coefficient to obtain the upper limit value in the target energy consumption range, and then determine the target energy consumption range according to the upper limit value and the lower limit value in the target energy consumption range. Obtain the system energy efficiency ratio, and multiply the target energy consumption range by the system energy efficiency ratio to obtain the target total power range.

[0075] In a specific implementation, add up the solar radiation heat, human heat, body heat dissipation, and other heat sources in the test results to obtain the target thermal performance load, multiply the target thermal performance load by the target correction coefficient to obtain the target energy consumption range, and multiply the target energy consumption range by the system energy efficiency ratio to obtain the target total power range.

[0076] Step S203: Determine the target power range corresponding to the power-consuming component to be detected according to the target total power range.

[0077] It should be noted that determining the target power range corresponding to the power-consuming component to be detected according to the target total power range may be to first determine the power-consuming component to be detected, perform power distribution for the power-consuming component to be detected according to the target total power range and the rated power of the power-consuming component to be detected, allocate the lower limit power for each power-consuming component to be detected according to the lower limit value in the target total power range, allocate the upper limit power for each power-consuming component to be detected according to the upper limit value in the target total power range, and then determine the target power range corresponding to the power-consuming component to be detected according to the lower limit power and the upper limit power.

[0078] Further, in order to make the target power range corresponding to the power-consuming component to be detected more in line with actual applications, step S203 may include: determining the basic power consumption corresponding to the power-consuming component to be detected; determining the power consumption ratio between the power-consuming components to be detected according to the basic power consumption; and determining the target power range corresponding to each power-consuming component to be detected according to the power consumption ratio and the target total power range.

[0079] It should be noted that the basic power consumption may be the most common power consumption during the normal use of the power-consuming component to be detected. Determining the power consumption ratio between the power-consuming components to be detected according to the basic power consumption may be calculating the ratio of the basic power consumption of each power-consuming component to be detected. Determining the target power range corresponding to each power-consuming component to be detected according to the power consumption ratio and the target total power range may be to first determine the lower limit value of the target power of each power-consuming component to be detected according to the power consumption ratio and the lower limit value in the target total power range, then determine the upper limit value of the target power of each power-consuming component to be detected according to the power consumption ratio and the upper limit value in the target total power range, and then determine the target power range corresponding to each power-consuming component to be detected according to the lower limit value of the target power and the upper limit value of the target power of each power-consuming component to be detected.

[0080] This embodiment obtains the test results of the vehicle's environmental simulation test; determines the target total power range according to the test results; and determines the target power range corresponding to the power-consuming component to be detected according to the target total power range. This embodiment determines the target total power range according to the test results of the vehicle's environmental simulation test; and determines the target power range corresponding to the power-consuming component to be detected according to the target total power range. Furthermore, it judges whether there is an abnormality in the actual power of the power-consuming component to be detected, avoids the reduction of the cruising range and the increase of the user's charging cost due to the excessive power consumption of the power-consuming component to be detected, and reduces the user experience.
