Technical Field

[0001] This application relates to the field of communication technology, and more particularly to the field of hybrid vehicle power technology, specifically to an engine torque regulation method, device, equipment, storage medium, and vehicle. Background Technology

[0002] With the development of hybrid vehicle technology, the requirements for the precision of engine output torque are becoming increasingly higher.

[0003] In related technologies, due to variations in engine manufacturing and assembly, there is a technical problem where the actual output torque of the engine cannot reach the expected level. Summary of the Invention

[0004] This application provides an engine torque adjustment method, device, equipment, storage medium, and vehicle to at least solve the technical problem in related technologies where the actual output torque of the engine cannot reach the expected level. The technical solution of this application is as follows:

[0005] According to a first aspect of this application, an engine torque adjustment method is provided, comprising: acquiring the current torque of a generator in a vehicle and the target torque of an engine in the vehicle; the current torque of the generator being an output torque in response to the target torque; the generator being mechanically connected to the engine; determining a current deviation value of the vehicle; the current deviation value being the deviation between the current torque of the generator and the target torque; and if the current deviation value of the vehicle is not within a first preset range, adjusting the engine torque until the current deviation value of the vehicle is within the first preset range.

[0006] Based on the aforementioned technical means, this application can obtain the current torque of the generator in the vehicle and the target torque of the engine in the vehicle; and determine the current deviation value of the vehicle; if the current deviation value of the vehicle is not within a first preset range, the engine torque is adjusted until the current deviation value of the vehicle is within the first preset range. Thus, since the generator and engine in the vehicle are mechanically connected, the torques of the engine and generator are equal, and the current torque fed back by the generator is relatively accurate relative to the current torque of the engine; and by pre-determining whether the current deviation value of the vehicle is within the first preset range, and adjusting the engine torque when the current deviation value of the vehicle is outside the first preset range until the current deviation value of the vehicle is within the first preset range, the actual output torque of the engine can reach the expected level.

[0007] In one possible implementation, before obtaining the current torque of the generator in the vehicle, the method further includes: determining a generator torque deviation value; the generator torque deviation value is the deviation value of the generator torque within a preset time period; obtaining the current torque of the generator in the vehicle includes: if the generator torque deviation value is within a second preset range, then obtaining the current torque of the generator in the vehicle.

[0008] Based on the aforementioned technical means, this application can determine the generator torque deviation value; if the generator torque deviation value is within a second preset range, then the current torque of the generator in the vehicle can be obtained. Thus, since the generator torque deviation value being within the second preset range indicates that the operating state of the engine and generator is relatively stable, the obtained current torque of the generator is more accurate when the operating state of the engine and generator is relatively stable.

[0009] In one possible implementation, the above-described adjustment of engine torque includes: adjusting engine torque based on the vehicle's current deviation value and the generator's current speed.

[0010] Based on the aforementioned technical means, this application can adjust the engine torque by obtaining the current deviation value of the vehicle and the current speed of the generator, and then adjusting the engine torque according to the current deviation value of the vehicle and the current speed of the generator. Thus, a method for adjusting engine torque can be implemented based on the current deviation value of the vehicle and the current speed of the generator.

[0011] In one possible implementation, adjusting the engine torque based on the vehicle's current deviation value and the generator's current speed includes: performing a proportional adjustment operation to obtain a first current deviation value for the vehicle; the proportional adjustment operation includes adjusting the engine torque using a proportional adjustment method based on the vehicle's current deviation value and the generator's current speed; the first current deviation value is the updated current deviation value of the vehicle after adjusting the engine torque based on the proportional adjustment operation; if the first current deviation value is greater than a first preset threshold, the proportional adjustment operation is repeated until the first current deviation value is less than the first preset threshold; if the first current deviation value is less than the first preset threshold, an integral adjustment operation is performed to obtain a second current deviation value for the vehicle; the integral adjustment operation includes adjusting the engine torque using an integral adjustment method based on the vehicle's current deviation value; the second current deviation value is the updated current deviation value of the vehicle after adjusting the engine torque based on the integral adjustment operation; if the second current deviation value is outside a first preset range, the integral adjustment operation is repeated until the second current deviation value is within the first preset range; if the second current deviation value is within the first preset range, the adjustment of the engine torque is determined to be complete.

[0012] According to the above technical means, this application can obtain a first current deviation value of the vehicle by performing a proportional adjustment operation; if the first current deviation value is greater than a first preset threshold, the proportional adjustment operation is repeated until the first current deviation value is less than the first preset threshold; if the first current deviation value is less than the first preset threshold, an integral adjustment operation is performed to obtain a second current deviation value of the vehicle; if the second current deviation value is outside the first preset range, the integral adjustment operation is repeated until the second current deviation value is within the first preset range; if the second current deviation value is within the first preset range, the adjustment of the engine torque is determined to be complete. In this way, by determining whether to perform a proportional adjustment operation or an integral adjustment operation based on the first preset threshold, and by determining whether to perform an integral adjustment operation or complete the adjustment of the engine torque based on the second current deviation value, the engine torque after adjustment can be made closer to the target torque.

[0013] In one possible implementation, the above-mentioned proportional adjustment operation includes: querying a first correspondence based on the current deviation value of the vehicle and the current speed of the generator to obtain a target proportional adjustment torque, and adjusting the engine torque based on the target proportional adjustment torque; the first correspondence includes the correspondence between different current deviation values, different speeds of the generator and different proportional adjustment torques.

[0014] Based on the aforementioned technical means, this application can query the first correspondence between the vehicle's current deviation value and the generator's current speed to obtain the target proportional adjustment torque, and adjust the engine torque based on the target proportional adjustment torque. This achieves a method for adjusting engine torque through proportional adjustment operation.

[0015] In one possible implementation, the above-mentioned integral adjustment operation includes: querying a second correspondence based on the current deviation value of the vehicle to obtain the target integral adjustment torque, and adjusting the engine torque based on the target integral adjustment torque; the second correspondence includes the correspondence between different current deviation values ​​and different integral adjustment torques.

[0016] Based on the aforementioned technical means, this application can query the second correspondence based on the vehicle's current deviation value to obtain the target integral adjustment torque, and adjust the engine torque based on the target integral adjustment torque. This achieves a method for adjusting engine torque through integral adjustment operation.

[0018] In one possible implementation, the determining unit is further configured to determine a generator torque deviation value before acquiring the current torque of the generator in the vehicle; the generator torque deviation value is the deviation value of the generator torque within a preset time period; the acquiring unit is specifically configured to acquire the current torque of the generator in the vehicle if the generator torque deviation value is within a second preset range.

[0019] In one possible implementation, the aforementioned adjustment unit is specifically used to adjust the engine torque based on the vehicle's current deviation value and the generator's current speed.

[0020] In one possible implementation, the adjustment unit is specifically configured to: perform a proportional adjustment operation to obtain a first current deviation value of the vehicle; the proportional adjustment operation includes adjusting the engine torque using a proportional adjustment method based on the vehicle's current deviation value and the generator's current speed; the first current deviation value is the updated current deviation value of the vehicle after adjusting the engine torque based on the proportional adjustment operation; if the first current deviation value is greater than a first preset threshold, the proportional adjustment operation is repeated until the first current deviation value is less than the first preset threshold; if the first current deviation value is less than the first preset threshold, an integral adjustment operation is performed to obtain a second current deviation value of the vehicle; the integral adjustment operation includes adjusting the engine torque using an integral adjustment method based on the vehicle's current deviation value; the second current deviation value is the updated current deviation value of the vehicle after adjusting the engine torque based on the integral adjustment operation; if the second current deviation value is outside a first preset range, the integral adjustment operation is repeated until the second current deviation value is within the first preset range; if the second current deviation value is within the first preset range, the adjustment of the engine torque is determined to be complete.

[0021] In one possible implementation, the aforementioned adjustment unit is specifically used to: query a first correspondence based on the vehicle's current deviation value and the generator's current speed to obtain a target proportional adjustment torque, and adjust the engine torque based on the target proportional adjustment torque; the first correspondence includes the correspondence between different current deviation values, different generator speeds, and different proportional adjustment torques.

[0022] In one possible implementation, the aforementioned adjustment unit is specifically used to: query a second correspondence based on the current deviation value of the vehicle to obtain the target integral adjustment torque, and adjust the engine torque based on the target integral adjustment torque; the second correspondence includes the correspondence between different current deviation values ​​and different integral adjustment torques.

[0023] According to a third aspect provided in this application, an electronic device is provided, comprising: a processor; a memory for storing processor-executable instructions; wherein the processor is configured to execute instructions to implement the method of the first aspect described above and any possible implementation thereof.

[0026] According to a sixth aspect provided in this application, a vehicle is provided, comprising: a processor; a memory for storing processor-executable instructions; wherein the processor is configured to execute instructions such that the processor performs the method described in the first aspect and any possible implementation thereof.

[0027] It should be noted that the technical effects of any of the implementation methods in aspects two through six can be found in the technical effects of the corresponding implementation methods in aspect one, and will not be repeated here.

[0028] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and do not limit this application.

[0029] Therefore, the above-mentioned technical features of this application have the following beneficial effects:

[0030] (1) The current torque of the generator in the vehicle and the target torque of the engine in the vehicle can be obtained; and the current deviation value of the vehicle can be determined; if the current deviation value of the vehicle is not within the first preset range, the torque of the engine can be adjusted until the current deviation value of the vehicle is within the first preset range. In this way, since the generator and engine in the vehicle are mechanically connected, the torques of the engine and generator are equal, and the current torque fed back by the generator is more accurate than the current torque of the engine; and if the current deviation value of the vehicle is determined in advance whether it is within the first preset range, and if the current deviation value of the vehicle is outside the first preset range, the torque of the engine can be adjusted until the current deviation value of the vehicle is within the first preset range, so that the actual output torque of the engine can reach the expected value.

[0031] (2) The generator torque deviation value can be determined; if the generator torque deviation value is within the second preset range, the current torque of the generator in the vehicle can be obtained. In this way, since the generator torque deviation value is within the second preset range, it indicates that the working state of the engine and generator is relatively stable, so the current torque of the generator obtained is more accurate when the working state of the engine and generator is relatively stable.

[0032] (3) The engine torque can be adjusted by obtaining the current deviation value of the vehicle and the current speed of the generator, and based on the current deviation value of the vehicle and the current speed of the generator. In this way, a method for adjusting the engine torque can be realized based on the current deviation value of the vehicle and the current speed of the generator.

[0033] (4) A first current deviation value of the vehicle can be obtained by performing a proportional adjustment operation; if the first current deviation value is greater than a first preset threshold, the proportional adjustment operation is repeated until the first current deviation value is less than the first preset threshold; if the first current deviation value is less than the first preset threshold, an integral adjustment operation is performed to obtain a second current deviation value of the vehicle; if the second current deviation value is outside the first preset range, the integral adjustment operation is repeated until the second current deviation value is within the first preset range; if the second current deviation value is within the first preset range, the adjustment of the engine torque is determined to be complete. In this way, by determining whether to perform a proportional adjustment operation or an integral adjustment operation based on the first preset threshold, and by determining whether to perform an integral adjustment operation or determine the completion of the engine torque adjustment based on the second current deviation value, the engine torque after adjustment can be made closer to the target torque.

[0034] (5) The target proportional adjustment torque can be obtained by querying the first correspondence based on the current deviation value of the vehicle and the current speed of the generator, and the engine torque can be adjusted based on the target proportional adjustment torque. In this way, a method for adjusting engine torque through proportional adjustment operation is realized.

[0035] (6) The target integral adjustment torque can be obtained by querying the second correspondence based on the current deviation value of the vehicle, and the engine torque can be adjusted based on the target integral adjustment torque. In this way, a method for adjusting engine torque through integral adjustment operation is realized. Attached Figure Description

[0050] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0051] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0052] For ease of understanding, the engine torque adjustment method provided in this application will be described in detail below with reference to the accompanying drawings.

[0053] Figure 1 This is a flowchart illustrating an engine torque adjustment method according to an exemplary embodiment, such as... Figure 1 As shown, the engine torque adjustment method includes the following steps:

[0054] S101, The electronic equipment acquires the current torque of the generator in the vehicle and the target torque of the engine in the vehicle.

[0055] The current torque of the generator is the output torque in response to the target torque; the generator is mechanically connected to the engine.

[0056] As one possible implementation, the electronic devices obtain the current torque of the generator from the feedback signal sent by the generator control unit, and the target torque of the engine from the signal sent by the vehicle control unit to the engine control unit.

[0057] It should be noted that in P13 configuration and range-extended hybrid vehicles, the engine and generator are mechanically connected.

[0058] like Figure 2As shown, in practical applications, the vehicle control unit sends the target speed of the generator to the generator control unit via the controller area network bus communication, and sends the target torque of the engine in the vehicle to the engine control unit via the controller area network bus communication; the vehicle control unit receives the current torque and current speed of the generator sent by the generator control unit, and receives the current speed and current torque of the engine sent by the engine control unit.

[0059] S102. The electronic device determines the current deviation value of the vehicle.

[0060] The current deviation value is the deviation between the generator's current torque and the target torque.

[0061] As one possible implementation, the electronic device calculates the difference between the generator's current torque and the target torque, and determines this difference as the vehicle's current deviation value.

[0062] like Figure 3 As shown, in practical applications, the electronic equipment performs low-pass filtering on the current torque of the generator, with the filtering time being the first filtering time; the electronic equipment performs low-pass filtering on the target torque, with the filtering time being the second filtering time.

[0063] The electronic equipment calculates the difference between the generator's current torque and the target torque, and determines this difference as the vehicle's current deviation value.

[0064] Understandably, the electronic equipment performs low-pass filtering on the high-frequency components of the generator's current torque and target torque, based on pre-set first and second filtering times. This reduces interference in the generator's current torque and target torque, improving the accuracy of the vehicle's deviation values.

[0065] S103. The electronic device determines whether the current deviation value of the vehicle is within the first preset range.

[0066] S104. If the current deviation value of the vehicle is not within the first preset range, the electronic device adjusts the torque of the engine until the current deviation value of the vehicle is within the first preset range.

[0067] As one possible implementation, if the vehicle's current deviation value is not within the first preset range, the electronic device adjusts the engine torque by changing the engine intake air volume based on the vehicle's current deviation value and the generator's current speed, until the vehicle's current deviation value is within the first preset range.

[0068] As another possible implementation, if the current deviation value of the vehicle is not within the first preset range, the electronic device adjusts the engine torque by changing the engine ignition time interval based on the current deviation value of the vehicle and the current speed of the generator, until the current deviation value of the vehicle is within the first preset range.

[0069] Understandably, the technical solution provided in this application obtains the current torque of the generator in the vehicle and the target torque of the engine in the vehicle; and determines the current deviation value of the vehicle; if the current deviation value of the vehicle is not within a first preset range, the engine torque is adjusted until the current deviation value of the vehicle is within the first preset range. Thus, since the generator and engine in the vehicle are mechanically connected, the torques of the engine and generator are equal, and the current torque fed back by the generator is relatively accurate compared to the current torque of the engine; and by pre-determining whether the current deviation value of the vehicle is within the first preset range, and adjusting the engine torque when the current deviation value of the vehicle is outside the first preset range until the current deviation value of the vehicle is within the first preset range, the actual output torque of the engine can reach the expected level.

[0070] In some embodiments, in order to obtain the current torque of the generator in the vehicle, such as Figure 4 As shown, the engine torque adjustment method provided in this application embodiment further includes the following steps:

[0071] S201. Electronic equipment determines the generator torque deviation value.

[0072] Among them, the generator torque deviation value is the deviation of the generator torque within a preset time period.

[0073] As one possible implementation, the electronic device obtains the current torque value of the generator from the generator's feedback signal, and also obtains the current torque value of the generator from the generator's feedback signal before a preset time period. Furthermore, the electronic device calculates the difference between the two current torque values ​​and determines this difference as the generator torque deviation value.

[0074] S202. The electronic device determines whether the generator torque deviation value is within the second preset range.

[0075] S203. If the generator torque deviation value is within the second preset range, the electronic device obtains the current torque of the generator in the vehicle.

[0076] like Figure 5 As shown, in practical applications, the electronic device obtains the current torque value of the generator before a preset number of calculation cycles a, and obtains the current torque value of the generator in the current calculation cycle.

[0077] The electronic device calculates the generator torque deviation value in a preset number of calculation cycles a, performs low-pass filtering on the generator torque deviation value, and performs absolute value processing on the generator torque deviation value.

[0078] The electronic equipment determines whether the generator torque deviation value is less than or equal to a preset deviation threshold.

[0079] If the generator torque deviation is less than or equal to the preset deviation threshold, the electronic device will set the engine torque stability flag after a preset delay time and obtain the current torque of the generator in the vehicle.

[0080] If the generator torque deviation exceeds the preset deviation threshold, the electronic equipment will reset the engine stability flag.

[0081] If the engine stability indicator is set, the electronic equipment obtains the current torque value of the generator in the current calculation cycle.

[0082] It should be noted that setting the engine torque stability indicator indicates that the engine torque is stable; resetting the engine torque stability indicator indicates that the engine torque is unstable.

[0083] For example, the preset quantity is 10.

[0084] It is understood that the technical solution provided in this application determines the generator torque deviation value; if the generator torque deviation value is within a second preset range, the current torque of the generator in the vehicle is obtained. Thus, since the generator torque deviation value being within the second preset range indicates that the operating state of the engine and generator is relatively stable, the obtained current torque of the generator is more accurate when the operating state of the engine and generator is relatively stable.

[0085] In some embodiments, in order to adjust the torque of the engine, such as Figure 6 As shown, the torque adjustment of the engine in this embodiment includes the following steps:

[0086] S301. The electronic equipment acquires the current deviation value of the vehicle and the current speed of the generator.

[0087] S302. The electronic equipment adjusts the engine torque based on the vehicle's current deviation value and the generator's current speed.

[0088] As one possible implementation, the electronic device performs a proportional adjustment operation to obtain the vehicle's first current deviation value.

[0089] If the first current deviation value is greater than the first preset threshold, the electronic device repeats the proportional adjustment operation until the first current deviation value is less than the first preset threshold.

[0090] If the first current deviation value is less than the first preset threshold, the electronic device performs an integral adjustment operation to obtain the second current deviation value of the vehicle.

[0091] If the second current deviation value is outside the first preset range, the electronic device repeats the integral adjustment operation until the second current deviation value is within the first preset range.

[0092] If the second current deviation value is within the first preset range, the electronic device determines that the adjustment of the engine torque has been completed.

[0093] It should be noted that the proportional adjustment operation includes adjusting the engine torque using a proportional adjustment method based on the vehicle's current deviation value and the generator's current speed. The first current deviation value is the updated current deviation value of the vehicle after adjusting the engine torque based on the proportional adjustment operation. The integral adjustment operation includes adjusting the engine torque using an integral adjustment method based on the vehicle's current deviation value. The second current deviation value is the updated current deviation value of the vehicle after adjusting the engine torque based on the integral adjustment operation.

[0094] As is understood, the technical solution provided in this application obtains the current deviation value of the vehicle and the current speed of the generator, and adjusts the engine torque based on the current deviation value of the vehicle and the current speed of the generator. Thus, a method for adjusting engine torque can be implemented based on the current deviation value of the vehicle and the current speed of the generator.

[0095] In some embodiments, in order to ensure that the current deviation value of the vehicle is within a first preset range, such as Figure 7 As shown, in this embodiment of the application, the engine torque is adjusted based on the vehicle's current deviation value and the generator's current speed, including the following steps:

[0096] S401, The electronic device performs a proportional adjustment operation to obtain the vehicle's first current deviation value.

[0097] The proportional adjustment operation includes adjusting the engine torque according to the vehicle's current deviation value and the generator's current speed; the first current deviation value is the updated current deviation value of the vehicle based on the proportional adjustment operation to adjust the engine torque.

[0098] As one possible implementation, such as Figure 8 As shown, the electronic device queries the first correspondence based on the vehicle's current deviation value and the generator's current speed to obtain the target proportional adjustment torque, and adjusts the engine torque based on the target proportional adjustment torque.

[0099] The electronic equipment calculates the deviation value of the updated engine torque and determines this deviation value as the first current deviation value.

[0100] It should be noted that the first correspondence includes the correspondence between different current deviation values, different generator speeds, and different proportional adjustment torques.

[0101] S402, The electronic device determines whether the first current deviation value is less than the first preset threshold.

[0102] S403. If the first current deviation value is greater than the first preset threshold, the electronic device repeatedly performs the proportional adjustment operation until the first current deviation value is less than the first preset threshold.

[0103] S404. If the first current deviation value is less than the first preset threshold, the electronic device performs an integral adjustment operation to obtain the second current deviation value of the vehicle.

[0104] The integral adjustment operation includes adjusting the engine torque using an integral adjustment method based on the vehicle's current deviation value; the second current deviation value is the updated current deviation value of the vehicle based on the engine torque adjustment operation.

[0105] As one possible implementation, when the first current deviation value is less than the first preset threshold, the electronic device queries the second correspondence based on the vehicle's current deviation value to obtain the target integral adjustment torque, and adjusts the engine torque based on the target integral adjustment torque.

[0106] The electronic equipment calculates the updated deviation value of the engine torque and determines this deviation value as the second current deviation value.

[0107] It should be noted that the second correspondence includes the correspondence between different deviation values ​​and different integral adjustment torques.

[0108] In practical applications, such as Figure 9 As shown, if the absolute value of the first current deviation value is less than the first preset threshold, the electronic device retrieves the target integral adjustment torque from the second correspondence based on the vehicle's current deviation value.

[0109] The electronic device retrieves the upper and lower limits of the integral adjustment torque corresponding to the vehicle's current deviation value from a preset third correspondence.

[0110] If the target integral adjustment torque is greater than the lower limit of the integral adjustment torque but less than the upper limit of the integral adjustment torque, the electronic equipment adjusts the engine torque based on the target integral adjustment torque.

[0111] If the target integral adjustment torque is greater than the upper limit of the integral adjustment torque, the electronic equipment adjusts the engine torque according to the upper limit of the integral adjustment torque.

[0112] If the target integral adjustment torque is less than the lower limit of the integral adjustment torque, the electronic equipment adjusts the engine torque according to the lower limit of the integral adjustment torque.

[0113] S405. The electronic device determines whether the second deviation value is within the first preset range.

[0114] S406. If the second current deviation value is outside the first preset range, the electronic device repeats the integral adjustment operation until the second current deviation value is within the first preset range.

[0115] S407. If the second current deviation value is within the first preset range, the electronic device determines that the adjustment of the engine torque has been completed.

[0116] In practical applications, such as Figure 10 As shown, if the second deviation value is within the first preset range, the engine torque stability indicator is reset, and the electronic device confirms that the engine torque adjustment has been completed.

[0117] The target torque of the engine after adjustment is equal to the engine torque before adjustment, the sum of at least one target integral adjustment torque, and at least one target proportional adjustment torque.

[0118] Understandably, the technical solution provided in this application obtains a first current deviation value for the vehicle by performing a proportional adjustment operation. If the first current deviation value is greater than a first preset threshold, the proportional adjustment operation is repeated until the first current deviation value is less than the first preset threshold. If the first current deviation value is less than the first preset threshold, an integral adjustment operation is performed to obtain a second current deviation value for the vehicle. If the second current deviation value is outside a first preset range, the integral adjustment operation is repeated until the second current deviation value is within a first preset range. If the second current deviation value is within a first preset range, the torque adjustment of the engine is determined to be complete. Thus, by determining whether to perform a proportional adjustment operation or an integral adjustment operation based on a first preset threshold, and by determining whether to perform an integral adjustment operation or complete the torque adjustment of the engine based on the second current deviation value, the torque of the engine after adjustment can be made closer to the target torque.

[0119] In some embodiments, such as Figure 11 As shown, in practical applications, the electronic equipment adjusts the engine torque according to the torque adjustment indicator. Determining the torque adjustment indicator includes the following steps:

[0120] S501, Electronic equipment determines the current deviation value of the vehicle.

[0121] The current deviation value is the deviation between the generator's current torque and the target torque.

[0122] S502, Electronic devices acquire the engine's control mode.

[0123] The engine control modes include torque control mode and speed control mode.

[0124] As one possible implementation, electronic devices obtain the engine's control mode from feedback signals sent by the engine control unit.

[0125] S503, Electronic equipment acquires engine stability identification.

[0126] It should be noted that setting the engine torque stability indicator indicates that the engine torque is stable; resetting the engine torque stability indicator indicates that the engine torque is unstable.
