Description

Technical Field

[0001] The present application relates to the field of vehicle intelligent control technology, and in particular to a vehicle disconnect mechanism control method, electronic equipment and vehicle. Background Art

[0002] At present, in order to improve the economy of the whole vehicle, many pure electric four-wheel drive vehicles have added a disconnect mechanism to the auxiliary drive motor to reduce the energy loss caused by the permanent magnet motor at high speed. However, such a disconnect mechanism may be subjected to large impact torque and axial force when the vehicle is driving on complex road conditions, causing damage to the disconnect mechanism or even jamming. Summary of the invention

[0003] In view of this, the purpose of the present application is to propose a vehicle disconnect mechanism control method, electronic equipment and vehicle to prevent the disconnect mechanism from being subjected to a large impact, thereby preventing the disconnect mechanism from being damaged.

[0004] Based on the above purpose, the present application provides a vehicle disconnect mechanism control method, comprising:

[0005] Acquiring driving data of the vehicle, and judging whether the driving condition of the vehicle meets a preset risk condition based on the driving data;

[0006] In response to determining that the driving condition of the vehicle satisfies a preset risk condition, a current state of the disconnect mechanism is determined, and a shift restriction control is performed on the disconnect mechanism according to the current state.

[0007] Further, the driving data includes motor speed and wheel speed; and judging whether the driving condition of the vehicle meets a preset risk condition based on the driving data includes:

[0008] Determining fluctuation data of the motor speed;

[0009] determining whether the driving condition of the vehicle meets a preset risk condition based on the fluctuation data; and / or,

[0010] Determining a difference in wheel speeds on both sides of the vehicle;

[0011] Based on the difference, it is determined whether the driving condition of the vehicle meets the preset risk condition.

[0012] Due to drastic fluctuations in motor speed and differences in wheel speeds on both sides of the vehicle under complex road conditions such as bumpy roads, washboard roads, and icy and snowy roads, the system monitors and judges the fluctuation data and the difference in wheel speeds on both sides of the vehicle in real time, and takes corresponding control measures when the driving conditions meet the preset risk conditions. This prohibits the disconnect mechanism from engaging or disconnecting, reduces mechanical wear and damage, ensures stable and safe operation of the vehicle, and improves the reliability and durability of the disconnect mechanism.

[0013] Further, the fluctuation data includes the fluctuation amplitude and the fluctuation frequency of the motor speed; and judging whether the driving condition of the vehicle meets the preset risk condition based on the fluctuation data includes:

[0014] Determine the number of consecutive fluctuation periods in which the fluctuation data meets the preset fluctuation conditions;

[0015] In response to determining that the number of continuous fluctuation cycles is greater than or equal to a preset number, determining that the driving condition of the vehicle meets a preset risk condition;

[0016] The preset fluctuation condition includes that the fluctuation amplitude is greater than or equal to the preset fluctuation amplitude, and the fluctuation frequency is within a preset frequency range.

[0017] By collecting motor speed data and analyzing its fluctuation amplitude and frequency, abnormal fluctuations of the motor under complex road conditions can be identified. If the number of consecutive fluctuation cycles of the identified abnormal fluctuations is greater than or equal to the preset number, it indicates that the vehicle is in a bad road condition. Therefore, protective measures are taken, such as prohibiting the engagement or disconnection operation of the disconnecting mechanism, to reduce mechanical wear and damage, thereby improving the reliability and safety of the vehicle.

[0018] Further, the difference in wheel speeds of the wheels on both sides of the vehicle includes a first wheel speed difference between the left and right wheels of the front wheel of the vehicle and a second wheel speed difference between the left and right wheels of the rear wheel; and judging whether the driving condition of the vehicle meets the preset risk condition based on the difference includes:

[0019] In response to determining that the first wheel speed difference is greater than or equal to a preset wheel speed difference and the duration is greater than or equal to a preset duration, determining that the driving condition of the vehicle meets a preset risk condition; and / or,

[0020] In response to determining that the second wheel speed difference is greater than or equal to a preset wheel speed difference and the duration is greater than or equal to a preset duration, it is determined that the driving condition of the vehicle meets a preset risk condition.

[0021] By collecting the left and right wheel speed data of the front and rear wheels of the vehicle, the first wheel speed difference and the second wheel speed difference are calculated. If it is determined that the first wheel speed difference and / or the second wheel speed difference is greater than or equal to the preset wheel speed difference, and the duration is greater than or equal to the preset duration, it indicates that the vehicle is in a bad road condition at this time, and the operation of prohibiting the connection or disconnection of the disconnection mechanism can be adopted, which can reduce mechanical wear and damage, prevent the disconnection mechanism from getting stuck and mechanical failure, and improve the overall reliability and safety of the vehicle.

[0022] Further, the driving data includes a driving speed of the vehicle; and judging whether the driving condition of the vehicle meets a preset risk condition based on the driving data includes:

[0023] In response to determining that the driving speed is greater than or equal to a preset driving speed, it is determined whether the driving condition of the vehicle satisfies a preset risk condition based on the motor speed and / or the wheel speed.

[0024] Since misjudgment is prone to occur when judging whether the vehicle's driving condition meets the preset risk conditions at low speed or when parked, the vehicle's driving speed is first judged before judging the vehicle's driving condition based on the motor speed and wheel speed, ensuring that the judgment is made at a higher driving speed, thereby improving the accuracy of the judgment.

[0025] Further, the performing shift restriction control on the disconnect mechanism according to the current state includes:

[0026] In response to determining that the current state is a neutral state, prohibiting engagement of the disconnect mechanism;

[0027] In response to determining that the current state is a non-neutral state, the disconnect mechanism is prohibited from being disengaged.

[0028] The gear shift restriction control of the disconnect mechanism is performed according to the current state of the disconnect mechanism. Even if a corresponding operation request of the disconnect mechanism is detected, the request will be intercepted to prohibit the disconnect mechanism from engaging or disconnecting, thereby avoiding mechanical wear or damage of the disconnect mechanism and extending the service life of the disconnect mechanism.

[0029] Further, the performing shift restriction control on the disconnect mechanism according to the current state includes:

[0030] In response to determining that the current state is a state to be shifted, performing a shift operation, and determining a shift fork position of the shift fork of the disconnect mechanism when the shift operation is completed;

[0031] In response to the shift fork position existing in a preset shift position interval, determining that the shift is successfully engaged, and prohibiting the disconnection mechanism from being disconnected;

[0032] In response to the shift fork position not existing in the preset shift position interval, it is determined that the shift fails, and the disconnect mechanism is prohibited from engaging.

[0033] When the shift fork position exists in the preset shift position interval, it indicates that the shift is successful, the disconnection mechanism is prohibited from disconnecting, and any disconnection request of the disconnection mechanism is intercepted, which can ensure that the vehicle maintains stable power transmission when the shift is successfully shifted, and avoid mechanical damage to the disconnection mechanism due to erroneous disconnection. When the shift fork position does not exist in the preset shift position interval, it indicates that the shift fails, the disconnection mechanism is prohibited from engaging, and any disconnection mechanism engagement request is intercepted, which can avoid mechanical damage to the disconnection mechanism due to erroneous engagement, and improve the safety and reliability of the vehicle.

[0034] Further, the performing shift restriction control on the disconnect mechanism according to the current state includes:

[0035] In response to determining that the current state is a state to be shifted back, performing a shifting operation, and determining a shifting fork position of the shifting fork of the disconnect mechanism when the shifting operation is completed;

[0036] In response to the shift fork position existing in the preset shift-back position interval, it is determined that the shift-back is successful, and the engagement of the disconnection mechanism is prohibited;

[0037] In response to the shift fork position not existing in the preset shift-down position interval, it is determined that the shift-down fails, the disconnection mechanism is prohibited from disconnecting, and the current vehicle speed is adjusted to be less than the preset speed.

[0038] By monitoring the position of the shift fork at the end of the backshift operation to verify the success of the backshift operation, the accuracy of the backshift operation can be ensured. If the fork position exists in the preset backshift position range, it indicates that the backshift is successful; if the fork position does not exist in the preset backshift position range, it indicates that the backshift fails. Under complex road conditions or other high-risk working conditions, limiting the operation of the disconnect mechanism can ensure the stability of the vehicle during driving and avoid vehicle loss of control or other safety issues caused by misoperation of the disconnect mechanism.

[0039] Based on the same inventive concept, the present application also provides an electronic device, including a memory, a processor, and a computer program stored in the memory and executable by the processor, wherein the processor implements the method as described above when executing the computer program.

[0040] Based on the same inventive concept, the present application also provides a vehicle, which includes the above-mentioned electronic device.

[0041] From the above description, it can be seen that the vehicle disconnection mechanism control method, electronic device and vehicle provided by the present application, wherein the method includes: obtaining the driving data of the vehicle, and judging whether the driving condition of the vehicle meets the preset risk condition based on the driving data, so as to accurately identify the bad road condition; in response to determining that the driving condition of the vehicle meets the preset risk condition, determining the current state of the disconnection mechanism, and performing shift restriction control on the disconnection mechanism according to the current state. The disconnection mechanism can be made to perform shift restriction control on the disconnection mechanism when the vehicle is driving on a bad road with poor road conditions, prohibiting the disconnection mechanism from disconnecting or combining, and preventing the disconnection mechanism from being subjected to large impact torque and axial force, thereby avoiding damage to the disconnection mechanism, and even problems such as jamming, and extending the service life of the disconnection mechanism.

[0048] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0049] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present application should be the usual meanings understood by people with ordinary skills in the field to which the present application belongs.

[0050] In the related art, with the development of electric vehicle technology, pure electric four-wheel drive vehicles are gradually popularized in the market. Pure electric four-wheel drive vehicles usually adopt the power form of front permanent magnet synchronous motor (auxiliary drive) and rear permanent magnet synchronous motor to achieve better power performance and driving experience. However, in the actual driving process, especially under complex working conditions such as bumpy roads, washboard roads, and icy and snowy roads, the wheel speed of the vehicle will fluctuate violently, which brings new challenges to the disconnection mechanism in the four-wheel drive system. At present, in order to improve the economy of the whole vehicle, many pure electric four-wheel drive vehicles have added a disconnection mechanism to the auxiliary drive motor to reduce the energy loss generated by the permanent magnet motor under high-speed rotation. However, such a disconnection mechanism may be subjected to a large impact torque and axial force when the vehicle is driving on complex road conditions, resulting in damage to the disconnection mechanism, and even problems such as jamming. In order to avoid the occurrence of these problems, it is necessary to effectively protect and control the disconnection mechanism.

[0051] Based on the above problems, the applicant found that: obtaining the driving data of the vehicle, and judging whether the driving condition of the vehicle meets the preset risk condition based on the driving data; in response to determining that the driving condition of the vehicle meets the preset risk condition, determining the current state of the disconnection mechanism, and performing shift restriction control on the disconnection mechanism according to the current state. This can prevent the disconnection mechanism from being subjected to large impact torque and axial force when the vehicle is driving on complex road conditions, thereby avoiding damage to the disconnection mechanism, or even problems such as jamming, and extending the service life of the disconnection mechanism.

[0052] The embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0053] The present application provides a vehicle disconnect mechanism control method, such as Figure 1 As shown, in some embodiments, the method is executed by a vehicle controller or a data processor independently provided by the vehicle controller. The subsequent embodiments are all illustrated by taking the vehicle controller as an example; the method includes:

[0054] S101, obtaining driving data of a vehicle, and determining whether a driving condition of the vehicle meets a preset risk condition based on the driving data;

[0055] In specific implementation, the driving data includes but is not limited to motor speed and wheel speed; based on the motor speed and wheel speed, it is determined whether the driving condition of the vehicle meets the preset risk condition, and the preset risk condition refers to the condition that the disconnect mechanism may be subjected to greater impact force or wear. The motor speed and wheel speed are used to identify whether the driving condition of the vehicle will cause the disconnect mechanism to be subjected to greater impact force or wear. For example, when the motor speed fluctuation amplitude is greater than or equal to 600rpm and the fluctuation frequency is between 5Hz and 20Hz, and such fluctuation lasts for at least 3 cycles, it is deemed to meet the preset risk condition; or, when the left and right wheel speed difference of the front or rear wheels of the vehicle is greater than or equal to 250rpm and lasts for 1 second, it is deemed to meet the preset risk condition.

[0056] S102: In response to determining that the driving condition of the vehicle satisfies a preset risk condition, determining a current state of the disconnect mechanism, and performing shift restriction control on the disconnect mechanism according to the current state.

[0057] During specific implementation, it is determined that the driving condition of the vehicle meets the preset risk condition, indicating that the current road condition is poor, and the disconnect mechanism may be subjected to a large impact torque and axial force, resulting in damage to the disconnect mechanism. At this time, the current state of the disconnect mechanism is determined, and the gear shift restriction control of the disconnect mechanism is performed according to the current state. For example, if the current state is a neutral state, the disconnect mechanism is prohibited from engaging, and if the current state is a non-neutral state, the disconnect mechanism is prohibited from disconnecting, so as to avoid the disconnect mechanism from being subjected to a large impact during the engagement or disconnection process; if the current state is a state to be shifted, a shift operation is performed first, and at the end of the shift operation, the fork position of the shift fork of the disconnect mechanism is determined. If the fork position exists in the preset shift position interval, it indicates that the shift is successful at this time, and the disconnect mechanism is prohibited from disconnecting. If the fork position does not exist in the preset shift position interval, it indicates that the shift fails, and the disconnect mechanism is prohibited from engaging. If the current state is a state to be downshifted, the downshift operation is performed first, and when the downshift operation is completed, the fork position of the shift fork of the disconnect mechanism is determined; if the fork position exists in the preset downshift position interval, indicating that the downshift is successful, the disconnect mechanism is prohibited from engaging; if the fork position does not exist in the preset downshift position interval, indicating that the downshift fails, the disconnect mechanism is prohibited from disconnecting, and the current speed of the vehicle is adjusted to less than the preset speed; so as to effectively protect the disconnect mechanism under bad road conditions, avoid mechanical wear and damage caused by bad road conditions, thereby improving the reliability and safety of the entire vehicle and extending the service life of the disconnect mechanism.

[0058] In this embodiment, by judging whether the driving condition meets the preset risk condition based on the driving data (such as the motor speed and the wheel speed), the potential bad road condition can be timely identified under complex road conditions, and the gear shifting limit control of the disconnect mechanism can be performed according to the current state before the disconnect mechanism faces a large impact torque and axial force, thereby reducing mechanical wear and damage and extending the service life of the disconnect mechanism.

[0059] In some embodiments, the driving data includes motor speed and wheel speed; and judging whether the driving condition of the vehicle meets a preset risk condition based on the driving data includes:

[0060] Determining fluctuation data of the motor speed;

[0061] In specific implementation, the motor speed data is collected, and the motor speed sensor equipped in the vehicle monitors the motor speed in real time, and then determines the fluctuation data of the motor speed, such as the fluctuation amplitude and the fluctuation frequency. The fluctuation amplitude refers to the difference between the maximum and minimum values ​​of the motor speed within a certain time window. The fluctuation frequency refers to the number of times the motor speed fluctuates within a certain period of time.

[0062] Determining whether the driving condition of the vehicle meets a preset risk condition based on the fluctuation data;

[0063] In specific implementation, the judgment results of fluctuation amplitude and fluctuation frequency are comprehensively considered to determine whether the vehicle's driving condition meets the preset risk conditions. If the risk conditions are met, corresponding protective measures can be taken in time to prevent the disconnection mechanism from operating under adverse conditions, thereby reducing mechanical wear and damage and improving the reliability and safety of the vehicle.

[0064] Determining a difference in wheel speeds on both sides of the vehicle;

[0065] In specific implementation, each wheel of the vehicle is equipped with a wheel speed sensor, which monitors the rotation speed of each wheel in real time. Determining the difference in wheel speed of the wheels on both sides of the vehicle includes determining a first wheel speed difference between the left and right wheels of the front wheels of the vehicle and a second wheel speed difference between the left and right wheels of the rear wheels.

[0066] Based on the difference, it is determined whether the driving condition of the vehicle meets the preset risk condition.

[0067] In specific implementation, it is determined whether the driving condition of the vehicle meets the preset risk conditions based on the difference in wheel speeds on both sides of the vehicle. If the preset risk conditions are met, corresponding protective measures can be taken in time, such as restricting the operation of the disconnection mechanism (such as prohibiting engagement or disconnection) to avoid the operation of the disconnection mechanism under adverse conditions, thereby reducing mechanical wear and damage, improving the reliability and safety of the vehicle, and extending the service life of the disconnection mechanism.

[0068] In this embodiment, under complex road conditions such as bumpy roads, washboard roads, and icy and snowy roads, the motor speed will fluctuate violently, and the wheel speeds on both sides of the vehicle will differ. By real-time monitoring and judging the fluctuation data and the difference in wheel speeds on both sides of the vehicle, corresponding control measures (such as prohibiting the disconnection mechanism from engaging or disconnecting) can be taken when the driving conditions meet the preset risk conditions, effectively avoiding the disconnection mechanism from operating under adverse conditions, ensuring the stability and safety of the vehicle, and improving the reliability and durability of the disconnection mechanism.

[0069] In some embodiments, the fluctuation data includes the fluctuation amplitude and the fluctuation frequency of the motor speed; and judging whether the driving condition of the vehicle meets the preset risk condition based on the fluctuation data includes:

[0070] Determine the number of continuous fluctuation periods in which the fluctuation data meets a preset fluctuation condition; wherein the preset fluctuation condition includes that the fluctuation amplitude is greater than or equal to a preset fluctuation amplitude, and the fluctuation frequency is within a preset frequency range;

[0071] During specific implementation, it is necessary to first determine whether the fluctuation data meets the preset fluctuation conditions, and the preset fluctuation conditions include that the fluctuation amplitude is greater than or equal to the preset fluctuation amplitude (exemplarily, the preset fluctuation amplitude can be set to 600rpm), and the fluctuation frequency is within the preset frequency range (exemplarily, the preset frequency range can be set to 5Hz to 20Hz). If the fluctuation data meets the preset fluctuation conditions, the number of continuous fluctuation cycles in which the fluctuation data meets the preset fluctuation conditions is determined. A fluctuation cycle refers to the time period from one fluctuation peak value to the next fluctuation peak value (or from one fluctuation valley value to the next fluctuation valley value) of the motor speed. Continuously monitor the fluctuation of the motor speed and record the number of continuous fluctuation cycles that meet the preset fluctuation conditions. For example, if the fluctuation amplitude and fluctuation frequency of the motor speed meet the preset fluctuation conditions for 3 consecutive cycles, the number of continuous fluctuation cycles recorded is 3.

[0072] In response to determining that the number of consecutive fluctuation cycles is greater than or equal to a preset number, it is determined that the driving condition of the vehicle meets a preset risk condition.

[0073] In specific implementation, if it is determined that the number of continuous fluctuation cycles is greater than or equal to a preset number (for example, the preset number can be set to 3), indicating that the vehicle is in a bad road condition at this time, it is determined that the driving condition of the vehicle meets the preset risk condition. A protection mechanism can be immediately activated to prevent the disconnection mechanism from operating under adverse conditions. For example, the connection or disconnection operation of the disconnection mechanism is prohibited to reduce mechanical wear and damage.

[0074] In this embodiment, by collecting motor speed data and analyzing its fluctuation amplitude and fluctuation frequency, it is possible to identify abnormal fluctuations of the motor under complex road conditions, and take protective measures to effectively avoid the impact and wear of these fluctuations on the disconnection mechanism. The fluctuation of the motor speed is continuously monitored, and the number of continuous fluctuation cycles that meet the preset fluctuation conditions is recorded. For example, if the fluctuation amplitude and fluctuation frequency of the motor speed meet the preset fluctuation conditions for three consecutive cycles, the number of continuous fluctuation cycles is recorded as 3, which can more accurately identify high-risk situations under complex road conditions, so as to prohibit the connection or disconnection operation of the disconnection mechanism, reduce mechanical wear and damage, and improve the reliability and safety of the vehicle.

[0075] In some embodiments, the difference in wheel speeds of the wheels on both sides of the vehicle includes a first wheel speed difference between the left and right wheels of the front wheels of the vehicle and a second wheel speed difference between the left and right wheels of the rear wheels; and judging whether the driving condition of the vehicle meets the preset risk condition based on the difference includes:

[0076] In response to determining that the first wheel speed difference is greater than or equal to a preset wheel speed difference and the duration is greater than or equal to a preset duration, determining that the driving condition of the vehicle meets a preset risk condition;

[0077] In a specific implementation, the difference in wheel speeds of the wheels on both sides of the vehicle includes a first wheel speed difference between the left and right wheels of the front wheel of the vehicle and a second wheel speed difference between the left and right wheels of the rear wheel. For the first wheel speed difference, if the first wheel speed difference is greater than or equal to a preset wheel speed difference (exemplarily, the preset wheel speed difference can be set to 250rpm), and the duration is greater than or equal to a preset duration (exemplarily, the preset duration can be set to 1S), it is determined that the driving condition of the vehicle meets the preset risk condition;

[0078] In response to determining that the second wheel speed difference is greater than or equal to a preset wheel speed difference and the duration is greater than or equal to a preset duration, it is determined that the driving condition of the vehicle meets a preset risk condition.

[0079] In specific implementation, if the second wheel speed difference is greater than or equal to the preset wheel speed difference (exemplarily, the preset wheel speed difference can be set to 250rpm), and the duration is greater than or equal to the preset duration (exemplarily, the preset duration can be set to 1S), it is determined that the vehicle's driving condition meets the preset risk condition. The protection mechanism can be immediately activated to prevent the disconnection mechanism from operating under adverse conditions. For example, the engagement or disconnection operation of the disconnection mechanism is prohibited to reduce mechanical wear and damage, or the driver is notified of the current risk condition through the dashboard or other interface, prompting the driver to take necessary driving adjustments.

[0080] In this embodiment, the first wheel speed difference and the second wheel speed difference are calculated by collecting the left and right wheel speed data of the front and rear wheels of the vehicle. If it is determined that the first wheel speed difference and / or the second wheel speed difference is greater than or equal to the preset wheel speed difference, and the duration is greater than or equal to the preset duration, indicating that the vehicle is in a bad road condition at this time, then it is determined that the vehicle's driving condition meets the preset risk condition, so as to immediately start the protection mechanism to prevent the disconnection mechanism from operating under adverse conditions. For example, the engagement or disconnection operation of the disconnection mechanism is prohibited to reduce mechanical wear and damage, or the driver is notified of the current risk condition through the dashboard or other interface, prompting the driver to take necessary driving adjustments, which not only improves the stability and safety of the vehicle, but also prevents the disconnection mechanism from getting stuck and mechanical failure, reduces mechanical wear and damage, provides an intelligent protection mechanism, and improves the overall reliability and safety of the vehicle.

[0081] In some embodiments, the driving data includes a driving speed of the vehicle; and judging whether the driving condition of the vehicle meets a preset risk condition based on the driving data includes:

[0082] In response to determining that the driving speed is greater than or equal to a preset driving speed, it is determined whether the driving condition of the vehicle satisfies a preset risk condition based on the motor speed and / or the wheel speed.

[0083] In specific implementation, before judging whether the driving condition of the vehicle meets the preset risk condition based on the motor speed and / or wheel speed, it is necessary to first judge the driving speed of the vehicle. If it is determined that the driving speed is greater than or equal to the preset driving speed (for example, the preset driving speed can be set to 12kph), it indicates that at this driving speed, it is possible to more accurately judge whether the driving condition of the vehicle meets the preset risk condition based on the motor speed and / or wheel speed. Based on the comprehensive data of the vehicle driving speed, motor speed and wheel speed, it is accurately judged whether the driving condition of the vehicle meets the preset risk condition. Once the risk condition is met, corresponding protective measures are taken in time to prevent the disconnection mechanism from operating under adverse conditions, thereby reducing mechanical wear and damage and improving the reliability and safety of the vehicle.

[0084] In this embodiment, by first judging the driving speed of the vehicle before judging the driving condition of the vehicle based on the motor speed and the wheel speed, it is possible to ensure that the judgment is made at a higher driving speed. This is to avoid misjudgment at low speed or parking state and improve the accuracy of judgment. By comprehensively considering the driving speed, motor speed and wheel speed of the vehicle, it is possible to more accurately judge whether the driving condition of the vehicle under complex road conditions meets the preset risk conditions, and take corresponding protective measures in time. This not only improves the accuracy of judgment, but also enhances the safety of the vehicle under complex road conditions, optimizes the operation of the disconnection mechanism, reduces mechanical wear and damage, provides an intelligent protection mechanism, and improves the overall reliability and safety of the vehicle.

[0085] In some embodiments, the performing shift restriction control on the disconnect mechanism according to the current state includes:

[0086] In response to determining that the current state is a neutral state, prohibiting engagement of the disconnect mechanism;

[0087] During specific implementation, the current state of the disconnect mechanism is determined. If it is determined that the current state is a neutral state, the disconnect mechanism is prohibited from engaging, that is, the neutral state of the disconnect mechanism is maintained. Even if a request for engaging the disconnect mechanism is detected, the request will be intercepted and the disconnect mechanism is prohibited from engaging, so as to avoid mechanical wear or damage of the disconnect mechanism due to incorrect engagement.

[0088] In response to determining that the current state is a non-neutral state, the disconnect mechanism is prohibited from being disengaged.

[0089] In specific implementation, the current state of the disconnection mechanism is determined. If the current state is determined to be a non-neutral state, the disconnection mechanism is prohibited from disconnecting, that is, the non-neutral state of the disconnection mechanism is maintained. Even if a request for disconnection of the disconnection mechanism is detected, the request will be intercepted and the disconnection mechanism is prohibited from disconnecting, thereby avoiding mechanical wear or damage to the disconnection mechanism caused by erroneous disconnection. The stability and safety of the vehicle during driving are ensured, while the reliability and service life of the disconnection mechanism are improved. When the driving condition does not meet the preset risk condition and lasts for a certain period of time (such as 500ms), the disconnection mechanism is allowed to be disconnected or combined according to the vehicle request.

[0090] In this embodiment, by controlling the gear shift limit of the disconnect mechanism according to its current state, mechanical wear or damage caused by misoperation can be effectively avoided, thereby improving the stability and safety of the vehicle and extending the service life of the disconnect mechanism. This not only prevents mechanical problems caused by misoperation, but also improves the reliability of the disconnect mechanism and reduces the cost of maintenance and replacement.

[0091] In some embodiments, Figure 2 As shown, the shift limiting control of the disconnect mechanism according to the current state includes:

[0092] S201, in response to determining that the current state is a state to be shifted, performing a shift operation, and when the shift operation is completed, determining a shift fork position of the shift fork of the disconnect mechanism;

[0093] In specific implementation, if it is determined that the current state is a state to be shifted, it indicates that the current disconnect mechanism is in the process of shifting a gear. At this time, in order to ensure the normal function of the vehicle, an attempt is made to perform a shift operation, and at the end of the shift operation, the fork position of the shift fork of the disconnect mechanism is determined; and the success of the shift operation is verified by monitoring the position of the shift fork.

[0094] S202A, in response to the shift fork position being in a preset shift position interval, determining that the shift is successfully engaged, and prohibiting the disconnection mechanism from being disconnected;

[0095] In specific implementation, the shift fork position exists in a preset gear shift position range, which refers to the position range that the shift fork should be in when the gear shift is successful. The gear shift position range is usually pre-set based on the vehicle design and the mechanical characteristics of the shift mechanism. The shift fork position exists in the preset gear shift position range, indicating that the gear shift is successful, prohibiting the disconnect mechanism from disconnecting, and intercepting any request for the disconnect mechanism to disconnect, thereby ensuring that the vehicle maintains stable power transmission when the gear has been successfully shifted, and avoiding mechanical damage to the disconnect mechanism due to accidental disconnection.

[0096] S202B: In response to the shift fork position not existing in the preset shift position interval, it is determined that the shift fails, and the disconnection mechanism is prohibited from engaging.

[0097] In specific implementation, if the shift fork position does not exist in the preset gear shift position range, it indicates that the gear shift has failed, the disconnect mechanism is prohibited from engaging, and any request for the disconnect mechanism to engage is intercepted to avoid mechanical damage to the disconnect mechanism due to incorrect engagement, thereby improving the safety and reliability of the vehicle.

[0098] In this embodiment, by precisely controlling the shifting operation of the disconnect mechanism, mechanical wear or damage caused by misoperation can be effectively avoided, thereby improving the stability and safety of the vehicle and extending the service life of the disconnect mechanism. It not only ensures the accuracy of the shifting operation, but also prevents mechanical problems caused by misoperation, improves the reliability of the disconnect mechanism, and reduces the cost of maintenance and replacement. Through the intelligent protection mechanism, different driving conditions can be flexibly responded to while ensuring safety, reducing the operating burden of the driver, improving the overall reliability and safety of the vehicle, and enhancing the user's driving experience and satisfaction.

[0099] In some embodiments, Figure 3 As shown, the shift limiting control of the disconnect mechanism according to the current state includes:

[0100] S301, in response to determining that the current state is a state to be shifted back, performing a shifting operation, and determining a shifting fork position of the shifting fork of the disconnecting mechanism when the shifting operation is completed;

[0101] In specific implementation, if it is determined that the current state is a state to be shifted back, it indicates that the current disconnection mechanism is in the process of shifting back. At this time, in order to ensure the normal function of the vehicle, the shifting back operation is attempted, and at the end of the shifting back operation, the shifting fork position of the shifting fork of the disconnection mechanism is determined; and the success of the shifting fork is verified by monitoring the position of the shifting fork. The correctness of the shifting back operation and the stable operation of the vehicle are ensured.

[0102] S302A, in response to the shift fork position existing in the preset shift-back position interval, determining that the shift-back is successful, prohibiting the disconnection mechanism from engaging;

[0103] In specific implementation, the shift fork position exists in a preset backshift position range, which refers to the position range that the shift fork should be in when the backshift is successful. The forward gear position range is usually pre-set based on the vehicle design and the mechanical characteristics of the shift mechanism. The presence of the shift fork position in the preset backshift position range indicates that the backshift is successful, prohibiting the disconnect mechanism from engaging, intercepting any request for the disconnect mechanism to engage, and avoiding mechanical damage to the disconnect mechanism due to incorrect engagement.

[0104] S302B: In response to the shift fork position not existing in the preset shift down position interval, it is determined that the shift down fails, the disconnection mechanism is prohibited from disconnecting, and the current vehicle speed is adjusted to be less than the preset speed.

[0105] During specific implementation, the shift fork position does not exist in the preset shift down position range, indicating a shift down failure. The disconnect mechanism is prohibited from disconnecting, and any request for disconnect mechanism to disconnect is intercepted. At the same time, the current speed of the vehicle is adjusted to be less than a preset speed (exemplarily, the preset speed can be set to 40kph) to avoid mechanical damage to the disconnect mechanism due to excessive speed, thereby improving the safety and reliability of the vehicle.

[0106] In this embodiment, the accuracy of the backshift operation can be ensured by monitoring the position of the shift fork at the end of the backshift operation to verify the success of the backshift operation. If the fork position exists in the preset backshift position interval, it indicates that the backshift is successful; if the fork position does not exist in the preset backshift position interval, it indicates that the backshift fails. In this way, the result of the backshift operation can be identified and processed in a timely manner to ensure the normal operation of the vehicle. In complex road conditions or other high-risk conditions, the stability and safety of the vehicle are crucial. By limiting the operation of the disconnect mechanism, the stability of the vehicle during driving can be ensured, and vehicle loss of control or other safety problems caused by misoperation of the disconnect mechanism can be avoided.
