The torque detection device of the planetary gear hybrid vehicle can be implemented in the form of hardware and / or software, and the torque detection device of the planetary gear hybrid vehicle can be configured in the vehicle controller of the planetary gear hybrid vehicle. As Figure 1 shown, the method includes:

[0034] S110. Obtain a target operation data set corresponding to the target planetary gear hybrid vehicle.

[0035] Among them, the target planetary gear hybrid vehicle may refer to a planetary gear hybrid vehicle selected for abnormal torque signal detection. The operation data may refer to the data generated by the planetary gear hybrid vehicle during vehicle operation. Exemplarily, the operation data may include rotational speed and may also include torque. The target operation data set may refer to a set composed of various operation data corresponding to the target planetary gear hybrid vehicle.

[0036] S120. Numerically compare the target operating data set based on a preset comparison rule to generate a numerical comparison result, and determine the internal inspection result of the planetary gear set corresponding to the target planetary gear hybrid vehicle based on the numerical comparison result.

[0037] Among them, the preset comparison rule can refer to a rule preset for data evaluation of the operating data in the target operating data set.

[0039] S130. Based on the internal inspection result of the planetary gear set and the target vehicle networking platform, determine whether there is an abnormal torque in the target operating data set, and generate the drive wheel torque abnormal detection result corresponding to the target planetary gear hybrid vehicle.

[0040] Among them, the vehicle networking platform can refer to a platform that uses new generation information and communication technologies to achieve all-round network connections such as vehicle-to-vehicle, vehicle-to-road, and vehicle-to-person. The vehicle networking platform can provide various functions including traffic management, information services, and vehicle control by collecting and processing vehicle dynamic information. The target vehicle networking platform can refer to the vehicle networking platform selected for drive wheel torque abnormal detection. The drive wheel torque abnormal detection result can refer to the detection result obtained after drive wheel torque abnormal detection of the target planetary gear hybrid vehicle. Exemplarily, the drive wheel torque abnormal detection result can be that the drive wheel torque is abnormal, or can also be that the drive wheel torque is normal.

[0041] In an alternative embodiment, after determining the abnormal torque of the target operating data set based on the internal detection result of the planetary gear set and the target vehicle networking platform, and generating the abnormal drive wheel torque detection result corresponding to the target planetary hybrid vehicle, the following steps are further included: If the abnormal drive wheel torque detection result indicates abnormal drive wheel torque, determine the target vehicle control strategy corresponding to the target planetary hybrid vehicle based on the target vehicle networking platform and the historical vehicle control strategy, so as to perform vehicle adjustment on the target planetary hybrid vehicle through the target vehicle control strategy. Herein, the historical vehicle control strategy may refer to the vehicle control strategy corresponding to a vehicle with the same vehicle condition as the target planetary hybrid vehicle during normal operation within a historical time period. Generally, the historical vehicle control strategy can be obtained through the target vehicle networking platform. The target vehicle control strategy may refer to the vehicle control strategy corresponding to the target planetary hybrid vehicle generated based on the historical vehicle control strategy. Exemplarily, the historical vehicle control strategy can be directly used as the target vehicle control strategy corresponding to the target planetary hybrid vehicle, or the current vehicle control strategy corresponding to the target planetary hybrid vehicle can be adjusted based on the historical vehicle control strategy and the target operating data set corresponding to the target planetary hybrid vehicle to generate the target vehicle control strategy corresponding to the target planetary hybrid vehicle. The embodiments of the present invention do not specifically limit this.

[0042] Specifically, if the abnormal drive wheel torque detection result indicates abnormal drive wheel torque, the target vehicle networking platform can be used to request the vehicle control strategy corresponding to a vehicle with the same vehicle condition as the target planetary hybrid vehicle. When the vehicle with the same vehicle condition as the target planetary hybrid vehicle agrees to provide it, generate the target vehicle control strategy corresponding to the target planetary hybrid vehicle based on this vehicle control strategy, and send the target vehicle control strategy to the target planetary hybrid vehicle, so that the target planetary hybrid vehicle can perform vehicle adjustment according to the target vehicle control strategy. Thus, when the target planetary hybrid vehicle has abnormal drive wheel torque, it can promptly perform vehicle adjustment according to the target vehicle control strategy, ensuring the safety of the target planetary hybrid vehicle.

[0043] S140. Combine and process the internal detection result of the planetary gear set and the abnormal drive wheel torque detection result to obtain the target torque detection result corresponding to the target planetary hybrid vehicle.

[0044] Herein, the target torque detection result may refer to the complete torque detection result corresponding to the target planetary hybrid vehicle. Generally, the target torque detection result includes the internal detection result of the planetary gear set and the abnormal drive wheel torque detection result.

[0045] The technical solution of the embodiment of the present invention numerically compares the target operation data set corresponding to the target planetary hybrid vehicle through a preset comparison rule, generates a numerical comparison result, and determines the internal detection result of the planetary gear set corresponding to the target planetary hybrid vehicle based on the numerical comparison result. Furthermore, based on the internal detection result of the planetary gear set and the target vehicle networking platform, torque abnormality judgment is performed on the target operation data set to generate a drive wheel torque abnormality detection result corresponding to the target planetary hybrid vehicle. Finally, the internal detection result of the planetary gear set and the drive wheel torque abnormality detection result are combined and processed to obtain a target torque detection result corresponding to the target planetary hybrid vehicle. Since the collected torque signal is processed, the problems of low efficiency and accuracy of torque abnormality detection of planetary hybrid vehicles are solved, and the torque of planetary hybrid vehicles can be detected for abnormality quickly and accurately, improving the safety of planetary hybrid vehicles.

[0046] Embodiment 2

[0047] Figure 2 The flowchart of a torque detection method for a planetary hybrid vehicle provided in Embodiment 2 of the present invention is based on the above embodiment for refinement. In this embodiment, the operation of obtaining the target operation data set corresponding to the target planetary hybrid vehicle is specifically refined, which may specifically include: obtaining the basic operation data set corresponding to the target planetary hybrid vehicle; wherein, the basic operation data set includes a planetary sun gear operation data group, a planetary gear operation data group, and a ring gear operation data group; filtering the basic operation data set based on a preset weighted calculation method to obtain the target operation data set corresponding to the target planetary hybrid vehicle. As Figure 2 shown, the method includes:

[0048] S210. Obtain the basic operation data set corresponding to the target planetary hybrid vehicle; wherein, the basic operation data set includes a planetary sun gear operation data group, a planetary gear operation data group, and a ring gear operation data group.

[0049] Among them, the planetary gear set may refer to the core structure in the field of mechanical transmission. Generally, the planetary gear set assembly includes a sun gear, a planetary gear, a ring gear, and a carrier. The sun gear may refer to the component located at the center of the planetary gear set and meshing with the planetary gear. The planetary gear may refer to the component that rotates around the sun gear in the planetary gear set and is fixed by the carrier. The ring gear may refer to the external ring internal gear in the planetary gear set for wrapping the planetary gear. The carrier may refer to the component that supports the planetary gear and transmits power in the planetary gear set.

[0050] Among them, the planetary gear set sun gear operation data group may refer to a set composed of data generated under the operation state of the planetary gear set sun gear. Exemplarily, the planetary gear set sun gear operation data group may include a first rotational speed n1 and a first torque T1. The planetary gear operation data group may refer to a set composed of data generated under the operation state of the planetary gear. Exemplarily, the planetary gear operation data group may include a second rotational speed n2 and a second torque T2. The ring gear operation data group may refer to a set composed of data generated under the operation state of the ring gear. Exemplarily, the ring gear operation data group may include a third rotational speed n3 and a third torque T3. The basic operation data set may refer to a set composed of the initially collected planetary gear set sun gear operation data groups, planetary gear operation data groups, and ring gear operation data groups.

[0051] In an alternative embodiment, before obtaining the basic operation data set corresponding to the target planetary gear hybrid vehicle, it further includes: sending a start instruction to the target sensor corresponding to the target planetary gear hybrid vehicle through the target key switch corresponding to the target planetary gear hybrid vehicle; based on the start instruction, the target sensor performs data collection on the target planetary gear assembly corresponding to the target planetary gear hybrid vehicle to obtain the basic operation data set corresponding to the target planetary gear hybrid vehicle. Among them, the target key switch may refer to a core device that controls the vehicle power supply, start system, and some functions. Exemplarily, the target key switch may be a push-button start button or a traditional key. Through the target key switch, the start or shutdown of the vehicle control unit (VCU), instrument, and sensor devices in the target planetary gear hybrid vehicle can be controlled. The target sensor may refer to a sensor in the target planetary gear hybrid vehicle responsible for collecting operation data. Exemplarily, the target sensor may be a rotational speed sensor for collecting rotational speed or a torque sensor for collecting torque. Generally, one component in the target planetary gear hybrid vehicle corresponds to a set of target sensors. For example, the planetary gear set sun gear corresponds to a rotational speed sensor and a torque sensor. The target planetary gear assembly may refer to the planetary gear assembly corresponding to the target planetary gear hybrid vehicle.

[0052] Specifically, before performing torque anomaly detection on the target planetary gear hybrid vehicle, the user needs to initiate a start operation on the target key switch corresponding to the target planetary gear hybrid vehicle, so that the target key switch sends a start instruction to the target sensor corresponding to the target planetary gear hybrid vehicle based on the start operation. Furthermore, the target sensor performs data collection on the target planetary gear assembly corresponding to the target planetary gear hybrid vehicle to obtain the basic operation data set corresponding to the target planetary gear hybrid vehicle, and sends the basic operation data set to the vehicle control unit corresponding to the target planetary gear hybrid vehicle. Thus, an effective basis is provided for subsequent operations.

[0053] S220. Filter the basic operation data set based on a preset weighted calculation method to obtain a target operation data set corresponding to the target planetary-gear hybrid vehicle.

[0054] Among them, the preset weighted calculation method can refer to an algorithm preset for filtering each operation data in the basic operation data set. Exemplarily, the preset weighted calculation method can be the Least Mean Square (LMS) algorithm. For example: The LMS algorithm can be: y(n + 1) = w(n + 1) T x(n + 1), where w(n + 1) can represent the weighted weight. Specifically, w(n + 1) = w(n) + μ·e w (n)·x(n), where μ can represent the step factor, such as 0.02, ew(n) = w(n) T ·R(n)·x(n), R(n) = diag(1. / (1 + abs(e(n)))), e(n) can represent the error, e(n) = d(n) - y(n), d(n) can represent the desired signal, y(n) can represent the filtered output. Usually, y(n) = w(n) T x(n), w(n) can represent the filter weight, and x(n) can represent the input signal.

[0055] Specifically, after obtaining the basic operation data set corresponding to the target planetary-gear hybrid vehicle, the preset weighted calculation method can be used to filter each operation data in the basic operation data set. Thus, a target operation data set with interference and noise removed can be obtained, solving the problem in the prior art that due to the more complex structure of the planetary-gear hybrid vehicle compared with traditional vehicles, there are more torque signal interferences and noises, and the torque signals read by the vehicle controller are often inaccurate. The accuracy of the torque signal can be improved, and the accuracy of torque anomaly detection can be improved.

[0056] S230. Perform a numerical comparison on the target operation data set based on a preset comparison rule to generate a numerical comparison result.

[0057] Specifically, each target operation data in the target operation data set is the first speed n1 of the planetary sun gear, the first torque T1 of the planetary sun gear, the second speed n2 of the planet gear, the second torque T2 of the planet gear, the third speed n3 of the ring gear, and the third torque T3 of the ring gear. The speed comparison rule in the preset comparison rule is: The torque comparison rule is: Take... as an example. Then the numerical comparison result can be:

[0058] S240. Perform a format judgment on the numerical comparison result based on a preset data format, generate a format judgment result, and generate an internal planetary gearset abnormality result corresponding to the target planetary gearset hybrid vehicle based on the format judgment result.

[0059] Among them, the preset data format can refer to the rules preset for performing a format judgment on the numerical comparison result. Exemplarily, the preset data format can be that the rotational speed comparison result is proportional to the ratio of the number of teeth of the ring gear to the number of teeth of the sun gear, or that the torque comparison result is proportional to the rotational speed comparison result. The format judgment result can refer to the judgment result generated after performing a format judgment on the numerical comparison result using the preset data format. Exemplarily, the format judgment result can be that the format judgment is consistent or that the format judgment is inconsistent. The internal planetary gearset abnormality result can refer to the result of detecting abnormalities inside the planetary gearset based on the format judgment result. Exemplarily, the internal planetary gearset abnormality result can be that there is an abnormality inside the planetary gearset or that the inside of the planetary gearset is normal. Generally, if the format judgment result is that the format judgment is consistent, the internal planetary gearset abnormality result is that the inside of the planetary gearset is normal; conversely, if the format judgment result is that the format judgment is inconsistent, the internal planetary gearset abnormality result is that there is an abnormality inside the planetary gearset.

[0060] Specifically, following the above example, taking the preset data format as: where the negative sign indicates that the rotational directions of the sun gear and the ring gear are opposite, as an example. Then, the preset data format can be used to perform a format judgment on the numerical comparison result. If in the numerical comparison result and then the internal planetary gearset abnormality result corresponding to the target planetary gearset hybrid vehicle can be that the inside of the planetary gearset is normal; conversely, if any one of the format judgment results is that the format judgment is consistent, the internal planetary gearset abnormality result corresponding to the target planetary gearset hybrid vehicle can be that there is an abnormality inside the planetary gearset.

[0061] S250. Determine the internal planetary gearset abnormal component corresponding to the internal planetary gearset abnormality result based on the internal planetary gearset abnormality result and the preset component association relationship.

[0062] Among them, the preset component association relationship can refer to the association relationship of each component in the planetary gearset hybrid system preset in advance. Generally, the preset component association relationship can be determined according to the physical connection relationship of each component in the planetary gearset hybrid system. Figure 3The figure shows a schematic structural diagram of a planetary gear hybrid system provided by an embodiment of the present invention. Specifically, the planetary gear hybrid system includes an engine, an auxiliary motor, a main drive motor, a planetary gear set, and a system output shaft. Among them, the carrier in the planetary gear set is connected to the engine through a one-way clutch. The sun gear is connected to the auxiliary motor. The ring gear is connected to the main drive motor through a reduction pinion. The planet gears are connected to the engine. Therefore, the preset component association relationship can be set as: the sun gear is in an association relationship with the auxiliary motor, the ring gear is in an association relationship with the main drive motor, and the planet gears are in an association relationship with the engine.

[0063] Among them, the abnormal components inside the planetary gear set can refer to the components that may be abnormal in the planetary gear hybrid system. Exemplarily, the abnormal components inside the planetary gear set can be the auxiliary motor, the main drive motor, or the engine. Specifically, taking the first torque comparison result conforming to the torque comparison rule and the second torque comparison result not conforming to the torque comparison rule as an example, it can be shown that there is no data abnormality in the first torque T1 of the sun gear of the planetary gear set and the second torque T2 of the planet gears, while there is data abnormality in the third torque T3 of the ring gear. Thus, the main drive motor having a preset component association relationship with the ring gear can be used as the abnormal component inside the planetary gear set, solving the problem of torque abnormality positioning of the planetary gear hybrid vehicle and providing an effective basis for investigating the cause of torque abnormality of the planetary gear hybrid vehicle.

[0064] S260. Combine and process the internal abnormal result of the planetary gear set and the internal abnormal components of the planetary gear set to obtain the internal detection result of the planetary gear set corresponding to the target planetary gear hybrid vehicle.

[0065] Specifically, after generating the internal abnormal result of the planetary gear set and the internal abnormal components of the planetary gear set, the internal abnormal result of the planetary gear set and the internal abnormal components corresponding to the same target planetary gear hybrid vehicle can be combined and processed. Thus, the internal detection result of the planetary gear set corresponding to the target planetary gear hybrid vehicle is obtained.

[0066] In an optional embodiment, after determining the internal detection result of the planetary gear set corresponding to the target planetary gear set hybrid vehicle based on the numerical comparison result, the method further includes: determining a target message corresponding to the internal detection result of the planetary gear set in a preset message library based on the internal detection result of the planetary gear set, and sending the target message to a target instrument corresponding to the target planetary gear set hybrid vehicle through a controller area network bus, so that the target instrument realizes an abnormal alarm based on the target message. The preset message library may refer to a database preset for storing messages. Generally, the preset message library contains various pre-constructed messages, and each message contains an alarm method corresponding to a different abnormal type. Exemplarily, each message may include the number of beeps of a buzzer and the text display content of a liquid crystal display screen. The target message may refer to the message corresponding to the internal detection result of the planetary gear set in the preset message library. The target instrument may refer to the liquid crystal display screen included in the target planetary gear set hybrid vehicle.

[0067] Specifically, if the internal detection result of the planetary gear set includes an internal abnormality of the planetary gear set, the target message corresponding to the internal detection result of the planetary gear set can be determined in the preset message library, and the target message can be sent to the target instrument corresponding to the target planetary gear set hybrid vehicle through the controller area network bus. Thereby, the target instrument can display the prompt text "Internal abnormality of the planetary gear set" on the liquid crystal display screen, and trigger the buzzer to work according to the target message, realizing an abnormal alarm.

[0068] S270. If the internal detection result of the planetary gear set includes normal inside the planetary gear set, send the target operation data in the target operation data set to the target vehicle networking platform, so that the target vehicle networking platform performs a torque abnormality judgment on the target operation data based on historical torque data, and generates a drive wheel torque abnormality detection result corresponding to the target planetary gear set hybrid vehicle.

[0069] Among them, the historical torque data may refer to the torque data of a vehicle with the same vehicle condition as the target planetary gear set hybrid vehicle during a historical time period in an operating state. The torque abnormality judgment may refer to an operation of numerically judging the historical torque data and the target operation data by using a preset torque abnormality judgment rule.

[0070] Specifically, taking the torque anomaly judgment rule that the difference between the ring gear torque corresponding to the associated vehicle and the ring gear torque in the target operating data is greater than the set difference, such as 10, and exceeds 3 seconds, which is an example of abnormal drive wheel torque. If the internal detection result of the planetary gear set includes that the inside of the planetary gear set is normal, the third ring gear speed n3 and the third ring gear torque T3 in the target operating data can be sent to the target vehicle networking platform through the vehicle networking system (telematics box, tbox). Thus, the associated vehicle with the same vehicle condition information such as load, model, and driving condition as the target planetary hybrid vehicle is determined through the target vehicle networking platform, and a data access request is sent to the associated vehicle. When the associated vehicle agrees to the data access request, the ring gear torque corresponding to the associated vehicle is obtained, and torque anomaly judgment is performed on the ring gear torque corresponding to the associated vehicle and the ring gear torque in the target operating data according to the torque anomaly judgment rule, and the drive wheel torque anomaly detection result corresponding to the target planetary hybrid vehicle is generated.

[0071] It should be noted that in the embodiment of the present invention, if the drive wheel torque anomaly detection result is that the drive wheel torque is abnormal, the warning information can be sent back to the vehicle controller through the tbox, so that the vehicle controller determines the message corresponding to the drive wheel torque anomaly detection result in the preset message library and sends it to the target instrument. Furthermore, the target instrument realizes abnormal alarm based on the message. In addition, if the target key switch is turned off, the target instrument can be controlled to stop the buzzer and the liquid crystal display text work, and the instruction cache received by the target instrument can be cleared.

[0072] S280. Combine and process the internal detection result of the planetary gear set and the drive wheel torque anomaly detection result to obtain the target torque detection result corresponding to the target planetary hybrid vehicle.

[0073] The technical solution of the embodiment of the present invention filters the basic operation data set corresponding to the target planetary hybrid vehicle through a preset weighted calculation method to obtain the target operation data set corresponding to the target planetary hybrid vehicle. Furthermore, based on a preset comparison rule, a numerical comparison is performed on the target operation data set to generate a numerical comparison result. Further, based on a preset data format, a format judgment is made on the numerical comparison result to generate a format judgment result. Based on the format judgment result, an internal planetary row anomaly result corresponding to the target planetary hybrid vehicle is generated. Based on the internal planetary row anomaly result and a preset component association relationship, an internal planetary row anomaly component corresponding to the internal planetary row anomaly result is determined, and the internal planetary row anomaly result and the internal planetary row anomaly component are combined and processed to obtain an internal planetary row detection result corresponding to the target planetary hybrid vehicle. Further, if the internal planetary row detection result includes normal in the internal planetary row, the target operation data in the target operation data set is sent to the target vehicle networking platform, so that the target vehicle networking platform makes a torque anomaly judgment on the target operation data based on historical torque data to generate a drive wheel torque anomaly detection result corresponding to the target planetary hybrid vehicle. Finally, the internal planetary row detection result and the drive wheel torque anomaly detection result are combined and processed to obtain a target torque detection result corresponding to the target planetary hybrid vehicle. Since the collected torque signal is processed, the problems of low efficiency and low accuracy of torque anomaly detection of the planetary hybrid vehicle are solved, and the torque of the planetary hybrid vehicle can be quickly and accurately detected for anomaly, improving the safety of the planetary hybrid vehicle.
