[0047] Figure 2 This is a schematic diagram of a multi-speed hybrid electric drive assembly. Detailed Implementation

[0048] To make the purpose, technical solution, and advantages of this application clearer, the following will be described in conjunction with the appendix. Figure 1 and Figure 2 This application will be described in further detail. It is obvious that the described embodiments are merely some, not all, of the embodiments described herein. All other embodiments obtained by those skilled in the art based on the embodiments described herein without inventive effort are within the scope of protection of this application.

[0050] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

These terms are only used to distinguish the descriptions. For example, first may also be referred to as second without departing from the scope of the embodiments of this application, and similarly, second may also be referred to as first.

[0052] Depending on the context, the words “if” or “suppose” as used here can be interpreted as “when” or “in response to determination” or “in response to detection.” Similarly, depending on the context, the phrases “if determination” or “if detection (of the stated condition or event)” can be interpreted as “when determination” or “in response to determination” or “when detection (of the stated condition or event)” or “in response to detection (of the stated condition or event).”

[0054] It should be noted that any symbols and / or numbers present in the specification that are not marked in the accompanying drawings are not reference numerals.

[0055] First, to facilitate understanding of the hybrid transmission gear processing method provided in this application, the multi-speed hybrid electric drive assembly will now be explained.

[0056] like Figure 2As shown, the electric drive system is a P1+P3 structure. When the engine is not running, the C0 clutch is not engaged, the gear is in neutral, and the vehicle's power source is the drive motor, which is the pure electric mode. When the engine starts and drives the generator to generate electricity, the C0 clutch is not engaged, and the vehicle's power source is still the drive motor, which is the series mode. When the engine starts, the C0 clutch is engaged, the gear is in 1st or 2nd gear, the vehicle's main power source is the engine, and the drive motor assists in driving, which is the parallel mode.

[0057] When the vehicle switches between series and parallel operation modes, it requests the TCU to engage or disengage the gear. If the gear shifter malfunctions, the shift fork may not engage properly, preventing the vehicle from switching modes. If this malfunction is not addressed, it will affect the vehicle's power and fuel economy.

[0058] Figure 1 The method for handling gear positions in a hybrid transmission, as shown, includes the following steps:

[0059] S1: In response to the gear shifting command, determine whether the gear actuator meets the gear emergency conditions;

[0060] S2: If satisfied, collect the operating data of the gear shift actuator; wherein, the operating data includes at least: the position of the shift fork of the gear shift actuator, the hydraulic pressure, and the shift fork action time;

[0061] S3: Determine the failure type of the gear actuator based on its operating data;

[0062] S4: Based on the gear failure type and the number of failures, trigger the corresponding preset processing strategy to adjust the fluid operating parameters of the gear actuator; wherein, the fluid operating parameters include at least the oil pressure and flow rate of the gear actuator.

[0063] Specifically, this application determines in real time whether the gear shift actuator meets the emergency gear shift conditions in response to gear shift commands. When the conditions are met, it collects the shift fork position, oil pressure, and shift fork action time, enabling precise identification of abnormal states during gear shift execution. Based on the operational data, it further determines the failure type of the gear shift actuator, distinguishes different fault causes, and triggers corresponding preset processing strategies according to the gear shift failure type and number of failures. It dynamically adjusts the oil pressure and flow of the gear shift actuator to achieve precise intervention and rapid correction of gear shift actions. Compared with existing technologies, this invention can quickly respond to and classify unexpected gear shifting difficulties or disengagement obstacles under complex and changing road conditions, thereby shortening the duration of abnormal gear shift actions and avoiding problems such as hybrid mode switching failure, power interruption, and reduced fuel economy caused by prolonged gear shifting failure.

[0064] In one specific embodiment, S1: In response to the gear shifting command, determine whether the gear actuator meets the gear emergency conditions, specifically including:

[0065] In response to a gear shifting command, the gear actuator is controlled to perform a gear shifting operation; the gear shifting operation includes: disengaging and engaging gears;

[0066] If the gear shifting operation time is greater than or equal to a preset time threshold, the gear actuator is determined to meet the gear emergency condition, and the number of times the gear emergency condition is met is counted, and the count is used as the number of failures of the gear actuator.

[0067] It is understood that after issuing a gear shifting command, this application detects the gear shifting action time and compares it with a preset time threshold. Based on the comparison results, it can quickly and accurately identify unexpected faults such as obstruction or jamming during gear shifting or disengaging. At the same time, it accumulates and counts the number of times the gear emergency conditions are met, providing a reliable data foundation for subsequent graded fault tolerance, gradient boost and adaptive control. This achieves the pre-identification and accurate statistics of gear anomalies, avoiding technical problems such as power interruption and mode switching failure caused by failure to determine gear shifting timeout.

[0068] For example, if the gear shifting operation takes ≥2 seconds, it is determined that the gear actuator meets the emergency gear shifting conditions, and it indicates that the gear shifting failed.

[0069] In one specific embodiment, S3: Based on the operating data of the gear shift actuator, determine the failure type of the gear shift actuator, specifically including:

[0070] If the operating data of the gear actuator meets the first preset condition, then the failure type of the gear actuator is determined to be jamming failure;

[0071] The first presupposition condition is:

[0072] The hydraulic pressure is greater than or equal to the preset hydraulic pressure, and the shift fork action time is greater than or equal to the first preset time threshold, and the shift fork position falls within the first preset stroke range;

[0073] If the operating data of the gear actuator meets the second preset condition, then the failure type of the gear actuator is determined to be movement failure;

[0074] The second presupposition condition is:

[0075] The hydraulic pressure is greater than or equal to the preset hydraulic pressure, and the shift fork action time is greater than or equal to the second preset time threshold, and the shift fork position falls within the second preset stroke range;

[0076] Wherein, the first preset time threshold is less than the second preset time threshold;

[0077] The upper limit of the first preset travel range is less than the lower limit of the second preset travel range.

[0078] Specifically, this application collects multi-dimensional operational data such as oil pressure, shift fork action time, and shift fork position, and pre-sets first and second preset conditions to accurately distinguish the types of gear execution failures. In terms of design, it utilizes the interval division of the first preset time threshold being less than the second preset time threshold and the first preset travel range upper limit being less than the second preset travel range lower limit, thereby quickly identifying the jamming failure type where the shift fork hardly moves and the mid-journey stoppage type where only part of the movement occurs. The advantage of this design is that it avoids the defect of traditional control that cannot distinguish the specific failure mode by judging the gear timeout. Moreover, this design can effectively improve the specificity and reliability of hybrid transmission gear failure handling.

[0079] The total stroke of the gear shift actuator in this embodiment is 0-25mm, the target gear position is 25mm, and the normal oil pressure is 5.2bar.

[0080] For example, if the hydraulic pressure of the gear shift actuator is 5.5 bar, the shift fork action time is 0.3 s > the first preset time threshold (0.2 s), and the shift fork position moves by 0.5 mm, falling into the range of 1-3 mm, then it is determined that the gear shift actuator is stuck in the execution process.

[0081] For example, if the hydraulic pressure of the gear shift actuator is 6 bar, the shift fork action time is 0.6 s > the second preset time threshold (0.5 s), and the shift fork position moves by 15 mm, falling within the range of 3-18 mm, then the gear shift actuator is determined to have failed to move.

[0082] In one specific embodiment, S4: Based on the gear failure type and the number of failures, trigger the corresponding preset processing strategy to adjust the fluid operation parameters of the gear actuator, specifically including:

[0083] If the number of failures is less than the threshold, the preset time threshold for the gear shifting operation will be lowered according to the number of failures in a preset unit.

[0084] If the failure type is "stuck failure", then the corresponding oil pressure superposition multiple value is obtained based on the number of failures;

[0085] If the failure type is a movement failure, the corresponding oil pressure superposition multiple and flow superposition multiple are obtained based on the number of failures; wherein, the oil pressure superposition multiple and the flow superposition multiple are both increased by a preset multiple based on the number of failures;

[0086] Based on the oil pressure superposition multiple and the flow rate superposition multiple, obtain the target oil pressure value and / or target flow rate value for the corresponding number of failures.

[0087] It is understood that this application collects the type and number of gear shift failures, triggers the corresponding preset processing strategy to adjust the fluid operation parameters of the gear shift actuator; at the same time, as the number of failures accumulates, the shift time threshold is gradually reduced, and the oil pressure and flow rate are increased accordingly. This can gradually enhance the driving capability and speed up the fault judgment response when the gear is abnormal, and achieve progressively enhanced fault-tolerant control. The design advantage of this application is that it can adjust the oil pressure and flow rate parameters according to different failure scenarios such as jamming and movement, thereby effectively avoiding the risk of power interruption caused by repeated abnormalities, and greatly improving the stability of gear shift execution and the reliability of vehicle operation of the hybrid transmission under complex working conditions.

[0088] For example, the preset number threshold in this embodiment is 3 times; when the gear actuator fails to execute for the first time and the failure type is jamming failure, the target oil pressure for the first failure is 1.2 times the normal oil pressure, and the target oil pressure for the second failure is 1.5 times the normal oil pressure.

[0089] If the gear shift actuator fails to execute for the first time and the failure type is movement failure, the target oil pressure for the first failure is 1.3 times the normal oil pressure and the target flow rate is 1.1 times the normal flow rate. The target oil pressure for the second failure is 1.5 times the normal oil pressure and the target flow rate is 1.4 times the normal flow rate.

[0090] The preset time threshold for shifting gears has been adjusted from 2 seconds for the first failure to 1.5 seconds for the next failure.

[0091] In one specific embodiment, S4: Based on the gear failure type and the number of failures, trigger the corresponding preset processing strategy to adjust the fluid operation parameters of the gear actuator, specifically including:

[0092] If the number of failures is the same as the number of failures threshold, then a gear execution prohibition command is generated based on the gear shifting command and the number of failures threshold;

[0093] Based on the gear position execution prohibition command, the current gear shifting action is terminated, and the vehicle's drive mode is switched to series mode or pure electric mode for driving, and corresponding gear position fault information is generated.

[0094] Specifically, this application generates a gear shift prohibition command when the number of failures equals a set threshold. By directly terminating the current gear shifting action, it avoids the dangerous situation of mechanical wear and continuous power interruption caused by invalid repeated attempts. At the same time, it switches the vehicle's drive mode to a series mode or pure electric mode that does not rely on mechanical gears, ensuring that the vehicle still has continuous driving capability under abnormal gear conditions, thereby preventing problems such as hybrid mode switching failure and power loss caused by gear shift failure. Simultaneously, it generates and reports fault information, realizing integrated control of fault identification, safety protection and system degradation operation, significantly improving the safety and driving continuity of the hybrid transmission under extreme fault scenarios.

[0095] In summary, this application provides a post-processing method for hybrid transmission gear position failures. When a hybrid transmission fails to engage or disengage a gear, the shift force and shift flow are gradually increased based on factors such as the number of engagement / disengagement failures, vehicle gear requests, and system status, in order to improve the success rate of engagement / disengagement and ensure vehicle driving requirements.
