[0029] Figure 1 is a flow chart of a method for detecting a vehicle ventilation device according to an embodiment of the present invention, wherein a ventilation device is deployed in a driving device of the vehicle, such as Figure 1 As shown, the method may include the following steps:

[0030] Step S101: Determine attribute information of the ventilation device.

[0031] In the technical solution provided in step S101 of the present invention, the attribute information can be used to indicate the type of the vehicle's ventilation device. The vehicle's ventilation device type can include closed and open types. For example, if the ventilation device type is closed, the ventilation device is a normally closed type. If the ventilation device type is open, the ventilation device is a normally open type. This is for illustrative purposes only and is not intended to be limiting.

[0032] In this embodiment, attribute information of the ventilation device is determined. Optionally, this embodiment identifies the ventilation device of the vehicle and obtains an identification result. The identification result may include location information and attribute information of the ventilation device. The location information may be used to indicate the location of the ventilation device in the drive unit. From the identification result, the attribute information of the ventilation device, that is, the type of the ventilation device, may be determined.

[0033] It should be noted that the above-mentioned driving equipment can be used to represent the electric drive products of a vehicle. The electric drive products of a vehicle may include: electric drive products of new energy vehicles and electric drive products of non-new energy vehicles. The electric drive products of a vehicle may include at least one of the following products or a combination thereof: a reducer, an electric motor, an inverter, a power battery, a charging system, a thermal management system and a battery management system, etc. These are only examples given here and are not specifically limited.

[0034] Step S102: determining an adjustment strategy suitable for the ventilation device based on the attribute information.

[0035] In the technical solution provided in step S102 of the present invention, the adjustment strategy can be used to represent a rule for adjusting the initial operating condition of the ventilation device. The adjustment strategy can include a first adjustment strategy and a second adjustment strategy. The first adjustment strategy can be used to represent a rule for adjusting the air pressure and the temperature of the initial operating condition, and the second adjustment strategy can be used to represent a rule for adjusting the temperature of the initial operating condition.

[0036] In this embodiment, after determining the attribute information of the ventilation device, an adjustment strategy suitable for the ventilation device is determined based on the attribute information. Optionally, this embodiment can determine the type of the ventilation device from the attribute information of the ventilation device after determining the attribute information of the ventilation device, and determine the adjustment strategy suitable for the ventilation device based on the determined type of the ventilation device. In other words, if the determined type of the ventilation device is a closed type, the adjustment strategy is determined to be an adjustment strategy suitable for closed-type ventilation devices; if the determined type of the ventilation device is an open type, the adjustment strategy is determined to be an adjustment strategy suitable for open-type ventilation devices.

[0037] Optionally, the type of the ventilation device can be determined from the attribute information of the ventilation device. For example, the type of the ventilation device can be obtained by performing feature extraction or feature recognition on the attribute information of the ventilation device. This is only an example and is not limited to a specific example.

[0038] Step S103: adjusting the initial operating condition to the target operating condition according to the adjustment strategy.

[0039] In the technical solution provided in the above step S103 of the present invention, the operating condition parameters of the above initial operating condition may be different from the operating condition parameters of the above target operating condition, and the above target operating condition may be used to enable the driving device to operate in a normal state.

[0040] In this embodiment, the initial operating condition may be used to represent the initial environment in which the ventilation device is located, and the target operating condition may be used to represent the target environment in which the ventilation device is to be located.

[0041] In this embodiment, the operating condition parameters of the initial operating condition may include the air pressure of the initial operating condition and the temperature of the initial operating condition, and the operating condition parameters of the target operating condition may include the air pressure of the target operating condition and the temperature of the target operating condition.

[0042] In this embodiment, after determining an adjustment strategy suitable for the ventilation device based on the attribute information, the initial operating condition is adjusted to the target operating condition in accordance with the adjustment strategy. Alternatively, in this embodiment, based on determining an adjustment strategy suitable for the ventilation device, the operating parameters of the initial operating condition of the ventilation device are adjusted to the operating parameters of the target operating condition in accordance with the adjustment strategy suitable for the ventilation device.

[0043] Optionally, if the adjustment strategy is an adjustment strategy adapted for a closed type ventilation device, the air pressure of the initial working condition is adjusted to the air pressure of the target working condition, and the air temperature of the initial working condition is adjusted to the air temperature of the target working condition according to the adjustment strategy adapted for a closed type ventilation device.

[0044] Optionally, if the adjustment strategy is an adjustment strategy adapted for an open-type ventilation device, the temperature of the initial operating condition is adjusted to the temperature of the target operating condition according to the adjustment strategy adapted for an open-type ventilation device.

[0045] Step S104 , in response to the target operating condition causing the driving device to operate in a normal state, the ventilation device is tested based on the current road condition of the vehicle to obtain a test result.

[0046] In the technical solution provided in the above step S104 of the present invention, the above detection result can be used to indicate the oil leakage degree of the ventilation device under the current road condition, and the oil leakage degree can change with the change of the target working condition and the current road condition.

[0047] In this embodiment, the current road condition may include: a flat road acceleration condition, a flat road deceleration condition, an uphill driving condition, a downhill driving condition, a left-turn driving condition, and a right-turn driving condition.

[0048] In this embodiment, after adjusting the initial operating condition to the target operating condition according to the adjustment strategy, in response to the drive device operating normally at the target operating condition, the ventilation device is tested based on the vehicle's current road condition to obtain a test result. Alternatively, in this embodiment, after adjusting the initial operating condition to the target operating condition, the drive device of the vehicle is operated normally at the adjusted target operating condition, and in response to the drive device of the vehicle operating normally, the ventilation device is tested based on the vehicle's current road condition to obtain a test result.

[0049] It should be noted that the vehicle ventilation device detection method of this application is applicable not only to specific types of vehicles (e.g., school buses and fire trucks), but also to other types of vehicles, including but not limited to trucks, buses, and cars. In other words, as long as the vehicle ventilation device detection scenario involves, regardless of the type of vehicle, the vehicle ventilation device detection method of this application can be used to detect the ventilation device.

[0050] In the aforementioned steps S101 to S104 of the present application, when testing the vehicle's ventilation device, after determining the attribute information of the vehicle's ventilation device, an adjustment strategy suitable for the ventilation device can be determined based on the determined attribute information of the ventilation device. According to the aforementioned adjustment strategy, the initial operating condition is adjusted to the target operating condition, and in response to the target operating condition being adjusted, the drive device is operated normally. Based on the current road condition of the vehicle, the ventilation device is tested to obtain a test result indicating the degree of oil leakage of the ventilation device under the current road condition. This achieves the purpose of improving the reliability of the ventilation device testing, thereby resolving the technical problem of low accuracy in detecting the degree of oil leakage of the ventilation device, and further achieving the technical effect of improving the accuracy of the detected degree of oil leakage of the ventilation device.

[0051] The above method of this embodiment is further introduced below.

[0052] As an optional embodiment, step S102 determines, based on the attribute information, an adjustment strategy suitable for the ventilation device, including: in response to the attribute information indicating that the type of the ventilation device is a closed type, determining the adjustment strategy to be a first adjustment strategy, wherein the first adjustment strategy is used to represent the rules for adjusting the air pressure of the initial working condition and the temperature of the initial working condition; in response to the attribute information indicating that the type of the ventilation device is an open type, determining the adjustment strategy to be a second adjustment strategy, wherein the second adjustment strategy is used to represent the rules for adjusting the temperature of the initial working condition.

[0053] In this embodiment, the first adjustment strategy may be used to represent a rule for adjusting the air pressure of the initial operating condition and the air temperature of the initial operating condition.

[0054] In this embodiment, after determining the attribute information of the ventilation device, in response to the attribute information indicating that the type of the ventilation device is a closed type, the adjustment strategy is determined to be the first adjustment strategy. Alternatively, this embodiment can determine the type of the ventilation device from the attribute information of the ventilation device after determining the attribute information of the ventilation device. If the determined type of the ventilation device is a closed type, the adjustment strategy is determined to be the first adjustment strategy. This achieves the purpose of determining an adjustment strategy suitable for the ventilation device, thereby achieving the technical effect of improving the adjustment accuracy of the working conditions.

[0055] In this embodiment, the second adjustment strategy may be used to represent a rule for adjusting the air temperature of the initial working condition.

[0056] In this embodiment, after determining the attribute information of the ventilation device, in response to the attribute information indicating that the type of the ventilation device is a closed type, the adjustment strategy is determined to be the first adjustment strategy. Alternatively, this embodiment, based on determining the attribute information of the ventilation device, can determine the type of the ventilation device from the attribute information of the ventilation device. If the determined type of the ventilation device is an open type, the adjustment strategy is determined to be the second adjustment strategy. This achieves the purpose of determining an adjustment strategy suitable for the ventilation device, thereby achieving the technical effect of improving the adjustment accuracy of the working conditions.

[0057] The following further introduces the steps of adjusting the initial operating condition to the target operating condition according to the adjustment strategy of this embodiment.

[0058] As an optional embodiment, step S103 adjusts the initial operating condition to the target operating condition according to the adjustment strategy, including: in response to the adjustment strategy being the first adjustment strategy, adjusting the air pressure of the initial operating condition to the air pressure of the target operating condition according to the first adjustment strategy, and adjusting the temperature of the initial operating condition to the temperature of the target operating condition; in response to the adjustment strategy being the second adjustment strategy, adjusting the temperature of the initial operating condition to the temperature of the target operating condition according to the second adjustment strategy.

[0059] In this embodiment, after determining an adjustment strategy suitable for the ventilation device based on the attribute information, in response to the adjustment strategy being the first adjustment strategy, the air pressure of the initial operating condition is adjusted to the air pressure of the target operating condition, and the air temperature of the initial operating condition is adjusted to the air temperature of the target operating condition in accordance with the first adjustment strategy. Alternatively, in this embodiment, based on determining an adjustment strategy suitable for the ventilation device, in response to the adjustment strategy being the first adjustment strategy, the air pressure of the ventilation device is adjusted to the air pressure of the target operating condition, and the air temperature of the initial operating condition of the ventilation device is adjusted to the air temperature of the target operating condition in accordance with the first adjustment strategy, thereby achieving the purpose of adjusting the operating condition and realizing the technical effect of ensuring the normal operation of the drive device.

[0060] In this embodiment, after determining an adjustment strategy suitable for the ventilation device based on the attribute information, in response to the adjustment strategy being the second adjustment strategy, the temperature of the initial operating condition is adjusted to the temperature of the target operating condition according to the second adjustment strategy. Alternatively, in this embodiment, based on determining an adjustment strategy suitable for the ventilation device, in response to the adjustment strategy being the second adjustment strategy, the temperature of the initial operating condition of the ventilation device is adjusted to the temperature of the target operating condition according to the second adjustment strategy. This achieves the purpose of adjusting the operating condition and thus realizes the technical effect of ensuring the normal operation of the drive device.

[0061] The following further describes the steps of testing the ventilation device based on the current road condition of the vehicle and obtaining the test results in this embodiment.

[0062] As an optional embodiment, step S104 detects the ventilation device based on the current road condition of the vehicle and obtains the detection result, including: searching for steady-state driving information and dynamic driving information that match the current road condition from the target database; and detecting the ventilation device based on the steady-state driving information and the dynamic driving information to obtain the detection result.

[0063] In this embodiment, the target database may include at least a mapping relationship between different road conditions and different driving information. The different road conditions may include current road conditions, and the different driving information may include steady-state driving information and dynamic driving information.

[0064] In this embodiment, the above-mentioned steady-state driving information can be used to represent information for controlling the vehicle to maintain a constant speed driving state under the current road conditions.

[0065] In this embodiment, the dynamic driving information may be used to indicate information for controlling the vehicle to maintain one of the following states under the current road conditions: a speed-changing driving state, a slope driving state, and a turning driving state.

[0066] In this embodiment, after adjusting the initial operating condition to the target operating condition according to the adjustment strategy, steady-state driving information and dynamic driving information that match the current road condition are searched from the target database. Optionally, after adjusting the initial operating condition to the target operating condition, this embodiment sequentially matches different road conditions with the current road condition in the target database until one of the different road conditions matches the current road condition. Driving information that matches the road condition that matches the current road condition is then determined, and the steady-state driving information and dynamic driving information included in the driving information are determined as the steady-state driving information and dynamic driving information that match the current road condition. This achieves the purpose of searching for steady-state driving information and dynamic driving information that match the current road condition.

[0067] In this embodiment, after searching the target database for steady-state driving information and dynamic driving information that match the current road conditions, the ventilation device is tested based on the steady-state driving information and the dynamic driving information to obtain a test result. Alternatively, this embodiment, based on the steady-state driving information and dynamic driving information that match the current road conditions, tests the ventilation device based on each of the steady-state driving information and the dynamic driving information to obtain corresponding test results. This achieves the purpose of detecting the extent of oil leakage in the ventilation device, thereby achieving the technical effect of improving the accuracy of the detected extent of oil leakage in the ventilation device.

[0068] The following further describes the steps of testing the ventilation device based on steady-state driving information and dynamic driving information to obtain the test results of this embodiment.

[0069] As an optional embodiment, the ventilation device is detected based on steady-state driving information and dynamic driving information to obtain detection results, including: detecting the ventilation device under the preceding steady-state driving information in the steady-state driving information to obtain a first detection result; detecting the ventilation device under the dynamic driving information to obtain a second detection result; detecting the ventilation device under the subsequent steady-state driving information in the steady-state driving information to obtain a third detection result; at least the first detection result, the second detection result and the third detection result are determined as the detection results.

[0070] In this embodiment, the first detection result may be used to indicate the degree of oil leakage of the ventilation device under the preceding steady-state driving information.

[0071] In this embodiment, after searching the target database for steady-state driving information and dynamic driving information that match the current road conditions, the ventilation device is tested based on the preceding steady-state driving information within the steady-state driving information to obtain a first test result. Alternatively, based on the search for steady-state driving information and dynamic driving information that match the current road conditions, this embodiment can determine the preceding steady-state driving information and the following steady-state driving information within the steady-state driving information. Subsequently, the ventilation device is tested based on the determined preceding steady-state driving information to obtain a first test result, namely, the degree of oil leakage in the ventilation device based on the preceding steady-state driving information. This achieves the purpose of detecting the degree of oil leakage in the ventilation device, thereby achieving the technical effect of improving the accuracy of the detected degree of oil leakage in the ventilation device.

[0072] In this embodiment, the second detection result can be used to indicate the degree of oil leakage of the ventilation device under dynamic driving information.

[0073] In this embodiment, after searching the target database for steady-state driving information and dynamic driving information that match the current road conditions, the ventilation device is tested under the dynamic driving information to obtain a second test result. Alternatively, based on the search for steady-state driving information and dynamic driving information that match the current road conditions, this embodiment also tests the ventilation device under the determined dynamic driving information to obtain a second test result, namely, the degree of oil leakage in the ventilation device under the dynamic driving information. This achieves the purpose of detecting the degree of oil leakage in the ventilation device, thereby achieving the technical effect of improving the accuracy of the detected degree of oil leakage in the ventilation device.

[0074] In this embodiment, the third detection result can be used to indicate the degree of oil leakage of the breather device under the post-steady-state driving information.

[0075] In this embodiment, after searching the target database for steady-state driving information and dynamic driving information that match the current road conditions, the ventilation device is tested under the post-steady-state driving information in the steady-state driving information to obtain a third test result. Alternatively, this embodiment can determine the pre-steady-state driving information and post-steady-state driving information in the steady-state driving information based on the search for steady-state driving information and dynamic driving information that match the current road conditions. Subsequently, the ventilation device is tested under the determined post-steady-state driving information to obtain a third test result, namely, the degree of oil leakage in the ventilation device under the post-steady-state driving information. This achieves the purpose of detecting the degree of oil leakage in the ventilation device, thereby achieving the technical effect of improving the accuracy of the detected degree of oil leakage in the ventilation device.

[0076] In this embodiment, after obtaining the first, second, and third detection results, at least the first, second, and third detection results are determined as the detection result. Alternatively, this embodiment may determine the first, second, and third detection results as the detection result based on the first, second, and third detection results. That is, the oil leakage level of the ventilation device under the pre-positioned steady-state driving information, the oil leakage level of the ventilation device under the dynamic driving information, and the oil leakage level of the ventilation device under the post-positioned steady-state driving information are determined as the oil leakage level of the ventilation device under the current road conditions. This achieves the purpose of detecting the oil leakage level of the ventilation device, thereby achieving the technical effect of improving the accuracy of the detected oil leakage level of the ventilation device.

[0077] The following further describes the steps for obtaining the detection results of the ventilation device according to this embodiment.

[0079] In this embodiment, the fourth detection result can be used to indicate the degree of oil leakage of the breather device in a high-speed driving state.

[0080] In this embodiment, after obtaining the first, second, and third detection results, the ventilation device is tested in response to the vehicle being in a high-speed driving state to obtain a fourth detection result. Alternatively, based on the first, second, and third detection results, this embodiment controls the vehicle to travel at a high speed, and then tests the ventilation device while the vehicle is in a high-speed driving state to obtain a fourth detection result, that is, the degree of oil leakage in the ventilation device under the high-speed driving state. This achieves the purpose of detecting the degree of oil leakage in the ventilation device, thereby achieving the technical effect of improving the accuracy of the detected degree of oil leakage in the ventilation device.

[0081] In this embodiment, in response to the vehicle being in a high-speed driving state, the ventilation device is tested, and after obtaining a fourth test result, the first, second, third, and fourth test results are determined as the test result.

[0084] In this embodiment, the candidate road condition is different from the current road condition. For example, if the current road condition is a flat road acceleration condition, the candidate road condition may be a flat road deceleration condition, an uphill road condition, a downhill road condition, a left turn road condition, or a right turn road condition. These are merely examples and are not intended to be limiting.

[0085] In this embodiment, candidate road conditions are determined from the target database and the candidate road conditions are determined as the current road conditions. Optionally, after completing the ventilation device test based on the current road conditions of the vehicle and obtaining the test results, this embodiment selects a road condition different from the current road condition from the target database as a candidate road condition. The candidate road condition is then determined as the current road condition, and steps S103 and S104 are continued.

[0086] In an embodiment of the present invention, when testing a vehicle's ventilation device, after determining attribute information of the vehicle's ventilation device, an adjustment strategy suitable for the ventilation device can be determined based on the determined attribute information of the ventilation device. According to the adjustment strategy, an initial operating condition is adjusted to a target operating condition, and in response to the target operating condition being adjusted, the drive device is operated normally. Based on the vehicle's current road conditions, the ventilation device is tested to obtain a test result indicating the degree of oil leakage in the ventilation device under the current road conditions. This improves the reliability of the ventilation device testing, thereby resolving the technical issue of low accuracy in detecting the degree of oil leakage in the ventilation device and achieving the technical effect of improving the accuracy of the detected degree of oil leakage in the ventilation device.

[0087] The technical solutions of the embodiments of the present invention are described below with reference to preferred implementation methods.

[0088] The degree of oil leakage from a vehicle's breather system varies under different operating conditions. However, in existing technologies, the breather system is often tested only under certain operating conditions, resulting in low reliability and, consequently, low accuracy in the detected oil leakage level.

[0089] To address the above-mentioned technical issues, embodiments of the present invention provide a method for testing a vehicle's ventilation device. When testing a vehicle's ventilation device, after determining attribute information of the vehicle's ventilation device, an adjustment strategy suitable for the ventilation device can be determined based on the determined attribute information of the ventilation device. According to the adjustment strategy, an initial operating condition is adjusted to a target operating condition, and in response to the target operating condition being adjusted, a drive device is caused to operate normally. Based on the vehicle's current road conditions, the ventilation device is tested to obtain a test result indicating the degree of oil leakage in the ventilation device under the current road conditions. This improves the reliability of the ventilation device testing, thereby resolving the technical issue of low accuracy in detecting the degree of oil leakage in the ventilation device and achieving the technical effect of improving the accuracy of the detected degree of oil leakage in the ventilation device.

[0090] In this embodiment, a dynamic ventilation test system for an electric drive product of a vehicle can be used to achieve a target operating condition adjusted to operate the drive device in a normal state, and based on the current road conditions of the vehicle, the ventilation device is tested to obtain a test result indicating the degree of oil leakage of the ventilation device under the current road conditions. For example, FIG2(a) is a schematic diagram of a dynamic ventilation test system for an electric drive product of a vehicle according to an embodiment of the present invention. As shown in FIG2(a), the system may include: an electric drive product of a vehicle 201, a product test carrier 202, an air pressure monitoring device 203, and an air temperature monitoring device 204. The electric drive product of the vehicle 201 can be installed on the product test carrier 202, which can be a new energy vehicle, a non-new energy vehicle, or a test bench. The air pressure monitoring device 203 can be in communication with the interior of the electric drive product of the vehicle 201, and the air temperature monitoring device 240 can be in communication with the interior of the electric drive product of the vehicle 201.

[0091] In this embodiment, the air pressure monitoring device 203 can be used to test and record the air pressure inside the electric drive product 201 of the vehicle in real time, thereby assisting in determining whether the ventilation device is turned on.

[0092] In this embodiment, the temperature monitoring device 204 can be used to test and record the gas temperature inside the vehicle's electric drive product 201 in real time, thereby assisting in determining whether the ventilation device is turned on and confirming the temperature rise status inside the vehicle's electric drive product 201.

[0093] In this embodiment, by executing a dynamic ventilation test method for an electric drive product of a vehicle, in response to the drive device operating normally under target operating conditions, the ventilation device can be tested based on the current road conditions of the vehicle, and a test result indicating the degree of oil leakage in the ventilation device under the current road conditions can be obtained. For example, Figure 2(b) is a flow chart of a dynamic ventilation test method for an electric drive product of a vehicle according to an embodiment of the present invention. As shown in Figure 2(b), the method may include the following steps:

[0094] Step S211: building a dynamic ventilation test system.

[0095] After the dynamic ventilation test system is built, the process proceeds to step S212 to determine whether the ventilation device is a normally closed ventilation device.

[0096] In the technical solution provided in the above step S212 of the present invention, if it is determined that the ventilation device is not a normally closed ventilation device, the ventilation device is a normally open ventilation device.

[0097] If it is determined that the ventilation device is a normally closed ventilation device, the process proceeds to step S213 to adjust the initial air pressure and initial air temperature inside the electric drive product of the vehicle.

[0098] In the technical solution provided in step S213 of the present invention, it is required that the temperature inside the vehicle's electric drive product be at room temperature and the internal pressure be the same as the external atmospheric pressure before oil leak detection. The internal temperature can be regulated by natural cooling, and the internal temperature can be monitored and confirmed by the temperature monitoring device 204. The internal pressure can be regulated by temporarily connecting the interior of the vehicle's electric drive product to the external atmosphere, and the internal pressure can be monitored and confirmed by the pressure monitoring device 203.

[0099] If it is determined that the ventilation device is not a normally closed ventilation device, the process proceeds to step S214 to adjust the initial temperature inside the electric drive product of the vehicle.

[0100] In the technical solution provided in step S214 of the present invention, it is required that the temperature inside the electric drive product of the vehicle before the oil leak detection is room temperature. The internal temperature can be regulated by natural cooling, and the internal temperature can be monitored and confirmed by the temperature monitoring device 204.

[0101] After adjusting the initial temperature inside the electric drive product of the vehicle, proceed to step S215, step S216, step S27, step S219 and step S219.

[0102] After adjusting the initial air pressure and the initial temperature, the process proceeds to step S215 to run the pre-steady-state operating mode of the current road condition to obtain pre-steady-state driving information.

[0103] In the technical solution provided in the above step S215 of the present invention, the pre-steady-state operating condition of the current road condition is operated, and the vehicle travels at a constant speed at the initial speed under the pre-steady-state operating condition. When the air pressure value monitored by the air pressure monitoring device 203 does not increase with the increase of the temperature value monitored by the temperature monitoring device 204, it is confirmed that the normally closed ventilation device is open, and this step is terminated at this time.

[0104] After obtaining the preceding steady-state driving information, the process proceeds to step S216 to run the dynamic working mode of the current road condition to obtain dynamic driving information.

[0105] In the technical solution provided in the above step S216 of the present invention, the dynamic working condition of the current road condition is operated, and the automobile is converted from the previous steady-state working condition to the corresponding dynamic working condition as quickly as possible, and runs the dynamic working condition for a period of time, and then converted from the above dynamic working condition to the terminal vehicle speed of uniform driving as quickly as possible.

[0106] After obtaining the dynamic driving information, the process proceeds to step S217 to run the post-steady-state operating mode of the current road condition to obtain post-steady-state driving information.

[0107] In the technical solution provided in the above step S217 of the present invention, the post-steady state operating condition of the current road condition is run, the vehicle is driven at a constant speed at the end speed under the post-steady state operating condition, and the step is terminated after running for a certain period of time.

[0108] After obtaining the rear steady-state driving information, the process proceeds to step S218 to execute the oil leakage check condition.

[0109] In the technical solution provided in step S218 of the present invention, the breather device is tested in response to the vehicle being in a high-speed driving state to obtain a fourth test result. For example, in response to the vehicle being driven at a maximum constant speed on a flat road for a period of time, the breather device is tested and the fourth test result is obtained, thereby strengthening the verification of the degree of oil leakage in the breather device.

[0110] After running the oil leakage check condition, enter step S219 to evaluate whether the ventilation device has oil leakage.

[0111] After completing the oil leakage detection on the ventilation device of the vehicle in the current road condition, continue to perform the oil leakage detection on the ventilation device of the vehicle in the different road conditions by sequentially performing the above steps S212 to S219.

[0114] It should be noted that, as shown in Table 1 above, the above different road conditions may include: flat road acceleration condition, flat road deceleration condition, uphill driving condition, downhill driving condition, left turn driving condition and right turn driving condition.

[0115] The above-mentioned flat road acceleration conditions can be dynamic conditions in which a vehicle transitions from a constant speed to an accelerated state on a flat road, or vice versa.

The vehicle speed in the preceding steady-state condition can be the initial speed of the acceleration, and the vehicle speed in the subsequent steady-state condition can be the final speed of the acceleration.

[0116] The above-mentioned flat road deceleration conditions can be dynamic conditions in which a vehicle transitions from a constant speed to a decelerated state on a flat road, or vice versa.

[0117] The uphill driving condition described above can be a dynamic condition where a vehicle is traveling at a constant speed on a flat road and then transitioning to traveling uphill, or vice versa. The preceding steady-state condition for the uphill driving condition can be the vehicle traveling at a constant speed on a flat road; the dynamic condition for the uphill driving condition can be the vehicle transitioning from traveling at a constant speed on a flat road to traveling uphill, traveling uphill for a certain period of time, and then transitioning back to traveling at a constant speed on a flat road; and the subsequent steady-state condition for the uphill driving condition can be the vehicle traveling at a constant speed on a flat road. The vehicle speed in the preceding steady-state condition can be the initial speed of the uphill driving, and the vehicle speed in the subsequent steady-state condition can be the final speed of the uphill driving.

[0118] The downhill driving condition can be a dynamic condition where a vehicle is traveling at a constant speed on a flat road and then transitioning to downhill driving, or vice versa. The preceding steady-state condition for the downhill driving condition can be the vehicle traveling at a constant speed on a flat road; the dynamic condition for the downhill driving condition can be the vehicle transitioning from traveling at a constant speed on a flat road to traveling downhill, traveling downhill for a certain period of time, and then transitioning back to traveling at a constant speed on a flat road; and the subsequent steady-state condition for the downhill driving condition can be the vehicle traveling at a constant speed on a flat road. The vehicle speed in the preceding steady-state condition can be the initial speed of the downhill driving, and the vehicle speed in the subsequent steady-state condition can be the final speed of the downhill driving.

[0119] The aforementioned left-turn driving conditions can be dynamic conditions where a vehicle transitions from a constant speed on a flat road to a left turn, and vice versa. The preceding steady-state condition for the left-turn driving condition can be a vehicle traveling at a constant speed on a flat road. The dynamic condition for the left-turn driving condition can be a vehicle transitioning from a constant speed on a flat road to a left turn, then turning left for a certain period of time, and then transitioning from a left turn to a constant speed on a flat road. The subsequent steady-state condition for the left-turn driving condition can be a vehicle traveling at a constant speed on a flat road. Furthermore, the vehicle speed in the preceding steady-state condition can be the initial speed of the left turn, and the vehicle speed in the subsequent steady-state condition can be the final speed of the left turn.

[0120] The above-mentioned right-turn driving conditions can be dynamic conditions in which a vehicle transitions from a constant speed on a flat road to a right turn, and vice versa.

The vehicle speed in the preceding steady-state condition can be the initial speed of the right turn, and the vehicle speed in the subsequent steady-state condition can be the final speed of the right turn.

[0121] For example, according to the operating parameters shown in Table 1, run the pre-steady-state operating condition of a certain road condition, and drive at a constant speed as shown in the table. When the air pressure value monitored by the air pressure monitoring device 203 does not increase with the increase of the temperature value monitored by the temperature monitoring device 204, it is confirmed that the normally closed ventilation device is open, and this step is ended.

[0122] As another example, a dynamic operating condition is run on a specific road condition using the operating condition parameters shown in Table 1. Using the flat road acceleration condition as an example, the dynamic operating condition test process is explained in detail. The same applies to other road conditions: The vehicle transitions from a constant speed of 20 km / h to an accelerated state at full throttle as quickly as possible. This state is maintained until the vehicle reaches 150 km / h. Then, the vehicle transitions from the accelerated state to a constant speed of 150 km / h by adjusting the throttle as quickly as possible.

[0123] For another example, according to the operating parameters shown in Table 1, the post-steady state operating condition of a certain road condition is operated, and the vehicle is driven at a constant speed as shown in the table. After operating for 1 minute, the step is terminated.

[0124] For example, the oil leakage inspection condition is to run the car at a maximum speed of 210km / h on a flat road for 5 minutes to strengthen the verification of the oil leakage of the ventilation device.

[0125] In this embodiment, after establishing a dynamic ventilation test system, the initial air pressure and initial temperature within the vehicle's electric drive product are adjusted, or the initial temperature within the vehicle's electric drive product is adjusted, by determining whether the ventilation device is a normally closed ventilation device. Next, a pre-steady-state operating condition is run for the current road condition to obtain pre-steady-state driving information, a dynamic operating condition is run for the current road condition to obtain dynamic driving information, and a post-steady-state operating condition is run for the current road condition to obtain post-steady-state driving information. Thereafter, an oil leak check condition is run to evaluate whether the ventilation device is leaking. This improves the reliability of ventilation device testing, thereby resolving the technical issue of low accuracy in detecting the degree of oil leakage in the ventilation device and achieving the technical effect of improving the accuracy of detecting the degree of oil leakage in the ventilation device.
