Description

Technical Field

[0001] The present invention relates to the technical field of vehicle control, and in particular to a vehicle control method and a vehicle. Background Art

[0002] Currently, driving mode selection has become a key factor in enhancing the driving experience and vehicle performance in vehicle control system design. Most vehicles offer a variety of driving mode options, such as economy mode, sport mode, and off-road mode, to suit different driver preferences and road conditions. These modes allow users to pre-select them through the vehicle's screen or other interfaces to adjust the vehicle's power response, shifting strategy, steering sensitivity, and other driving characteristics. For example, in economy mode, the vehicle tends to shift gears at lower speeds to maximize fuel efficiency; in sport mode, shift timing is delayed to provide a stronger power response.

[0003] However, while preset driving modes offer a degree of personalization and flexibility for the driver, these settings remain essentially static. Once selected, the vehicle operates according to the predefined strategy for that mode, without proactively adjusting to changing road conditions. Consequently, the technical issue of low gear control accuracy persists.

[0004] Currently, no effective solutions have been proposed for the above technical problems. Summary of the Invention

[0020] In an embodiment of the present invention, if vehicle control is required, vehicle status information can be acquired in real time while the vehicle is traveling.

[0026] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0027] It should be noted that the terms "first", "second", etc. in the description and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0028] According to an embodiment of the present invention, an embodiment of a vehicle control method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0029] Figure 1 is a flow chart of a vehicle control method according to an embodiment of the present invention. Figure 1 As shown, the method may include the following steps:

[0030] Step S102: Acquire vehicle status information while the vehicle is traveling.

[0031] In the technical solution provided in step S102 of the present invention, the state information is used to represent the vehicle's current driving state on the road. It can be vehicle driving state data, such as a vehicle speed signal, a slope estimation signal, a turning radius signal, a vertical ground acceleration signal, a driving resistance signal, and a braking signal. It should be noted that the above vehicle state information is merely illustrative and is not specifically limited herein. Any state information that can be used to determine the operating conditions of the road on which the vehicle is currently traveling is within the scope of protection of the embodiments of the present invention.

[0032] In this embodiment, the vehicle status information can be obtained in real time while the vehicle is traveling.

[0033] Optionally, during vehicle driving, the collection of real-time status information forms the basis for the control system to understand the current operating status of the vehicle. The status information includes vehicle driving status data in multiple dimensions, such as vehicle speed signal (reflecting the current speed of the vehicle), slope estimation signal (reflecting the road slope), turning radius signal (reflecting the curvature of the vehicle's turn), vertical ground acceleration signal (reflecting the acceleration of the vehicle in the vertical direction, which can be used to identify bumps or off-road conditions), driving resistance signal (reflecting the external resistance encountered by the vehicle during driving, such as wind resistance, friction, etc.), and brake signal (reflecting the driver's braking behavior). The above-mentioned diverse status information covers the key dynamic parameters of the vehicle during driving, providing a rich basis for a comprehensive understanding of the vehicle's driving status.

[0034] Alternatively, acquiring this status information in real time while the vehicle is in motion means the control system can instantly monitor and respond to changing road conditions, which is crucial for ensuring the timeliness and accuracy of gear shift decisions. For example, when the vehicle suddenly enters an uphill section, real-time slope estimation can help the system quickly adjust the gear to maintain sufficient power output. Similarly, at highway speeds, the vehicle speed signal can be used to determine when to upshift to improve fuel economy.

[0035] It should be noted that the embodiments of the present invention are mainly aimed at the road condition identification and shift point correction performed when the vehicle driving mode is in the economy mode, so as to ensure the economic performance of vehicle driving.

[0036] Step S104 : determining a matching result between the state information and the preset state indicators of the candidate operating condition set.

[0037] In the technical solution provided in the above step S104 of the present invention, the matching result is used to indicate whether the state information satisfies the preset state index of the candidate operating condition in the candidate operating condition set.

[0038] In this embodiment, after the state information of the vehicle is acquired, the state information and the preset state indicators of the candidate operating condition set may be matched to obtain a matching result.

[0039] Optionally, the status information is compared with preset status indicators in a set of candidate operating conditions. The candidate operating condition set includes a variety of possible operating condition types, each of which has its own specific preset status indicators. For example, a highway operating condition may have a preset speed range, a slope threshold, and an upper limit on the turning radius; while a mountain road condition may focus on a slope threshold and the number of consecutive turns. By comparing the vehicle's current status information with these preset indicators, the system can determine whether the vehicle meets the conditions of a certain operating condition. The comparison process can produce a matching result, indicating the degree of consistency between the vehicle status information and the preset status indicators of a certain operating condition in the candidate operating condition set. If the information meets the preset status indicators of the operating condition, the matching result will be positive, indicating that the current operating condition is consistent with the preset operating condition; conversely, if the information does not meet the preset indicators, the matching result will be negative, indicating that the current operating condition does not belong to the candidate operating condition. This positive and negative matching result provides a key basis for the subsequent determination of the target operating condition.

[0040] Optionally, through precise matching results, the present invention can identify the most suitable road condition from multiple candidate conditions. Because each condition has detailed preset state indicators, the matching process can provide highly specific condition identification, ensuring the accuracy of shift decision correction.

[0041] It should be noted that the matching process described above in this embodiment of the present invention is dynamic and can be performed in real time as vehicle status information is updated. This means that even if the vehicle encounters a sudden change in road conditions (such as turning from a highway to a mountain road) during driving, the system can quickly identify and respond, adjusting the shift strategy to adapt to the new conditions.

[0042] In this embodiment of the present invention, a matching result is generated by comparing vehicle status information with a pre-defined set of candidate operating condition indicators, enabling accurate identification of the current operating condition. This process ensures the accuracy and real-time nature of shift decision corrections and is a key step in achieving dynamic operating condition adaptation and intelligent shift control within the present invention. This refined operating condition identification enables a better understanding of the vehicle's driving environment, enabling optimized shift strategy adjustments and improving overall vehicle performance.

[0043] Step S106 : Based on the matching result, determine the target operating condition that the road is currently in from the candidate operating condition set.

[0044] In the technical solution of step S106 of the present invention, the target operating condition is a candidate operating condition whose state information satisfies a preset state indicator as a result of the concentrated matching of candidate operating conditions.

[0045] In this embodiment, after determining the matching result between the state information and the preset state indicators of the candidate operating condition set, the target operating condition of the road can be determined from the candidate operating condition set based on the matching result.

[0046] Optionally, after completing the matching process between the state information and the preset state indicators of the candidate operating condition set (i.e., step S104), a target operating condition that fits the current vehicle driving condition is determined from the successfully matched candidate operating conditions. The above selection process determines the direction and details of the subsequent shift strategy adjustment.

[0047] Optionally, each matching result corresponds to a candidate operating condition, indicating whether the vehicle status information meets the preset status indicators of the operating condition. A matching result may return a corresponding matching result, indicating that the vehicle status meets certain characteristics of the candidate operating condition. In order to formulate a clear and effective shift strategy, a target operating condition will be selected from the matching results based on certain priority rules or comprehensive evaluation. For example, if the vehicle speed is high, the slope is small, and the turning radius is large, then the vehicle may be prioritized to be in a highway operating condition rather than an urban road condition.

[0048] It's important to note that the operating condition selection isn't a one-time decision; it's dynamically adjusted based on real-time updates to vehicle status information during driving. This means that even if the initially determined operating condition no longer applies (e.g., when the vehicle enters a mountainous area), the new condition can be quickly identified and the shift strategy adjusted accordingly, ensuring the vehicle always maintains the most suitable driving state.

[0049] In an embodiment of the present invention, by matching status information with detailed preset indicators in a set of candidate operating conditions, the present invention can achieve refined identification of vehicle driving conditions. Compared with the simple operating condition classification in related technologies (such as only being divided into "city" and "highway"), it can distinguish more diverse operating condition types, such as highway, mountainous area, city, off-road and national highway, thereby providing more accurate shift control suggestions. Once the target operating condition is determined, it can be based on this specific identification result. This means that it will be possible to optimize the shift point according to the characteristics of the current road conditions, such as high speed, large turning radius or complex terrain, and adjust the parameters of functions such as neutral coasting or gear holding, so as to achieve appropriate performance of the vehicle under different driving conditions.

[0050] Step S108 : Based on the target operating condition, the initial shift strategy of the vehicle is adjusted to obtain an adjusted target shift strategy.

[0051] In the technical solution provided in step S108 of the present invention, the target shift strategy is used to represent the rules for executing the shift operation on the gear of the vehicle. The target shift strategy enables the vehicle to have an economic performance that is better than the economic performance of the vehicle enabled by the initial shift strategy.

[0052] In this embodiment, after determining the target operating condition of the road from the candidate operating condition set based on the matching results, the initial shifting strategy of the vehicle can be adjusted based on the target operating condition to obtain an adjusted target shifting strategy.

[0053] Optionally, after determining the target operating condition for the vehicle, the initial shift strategy can be optimized and adjusted based on the specific characteristics of the target operating condition to generate a new target shift strategy. The purpose of adjusting the shift strategy is to ensure more precise shifting operations to meet the requirements for economic performance, fuel economy, and driving comfort under different operating conditions.

[0054] Optionally, the target operating condition of the vehicle is determined based on the matching results. The target operating condition can include various operating conditions such as highways, mountain roads, urban roads, non-roads, or national highways. Each operating condition has its own unique road conditions, such as slope, vehicle speed, turning radius, etc., which have different requirements for the vehicle's shifting operations. The initial shift strategy may be a shift strategy that does not meet the conditions of the current target operating condition. For example, on a steep mountain road, the initial shift strategy may not provide sufficient torque to meet the challenge of going uphill; on a highway, in pursuit of economy, the gear may be shifted too early, affecting the power response.

[0055] Based on the characteristics of the target operating conditions, embodiments of the present invention propose corresponding shift strategy adjustment logic and rules. For example, in highway scenarios, the target shift strategy can be used to adjust the base shift point speed in economy mode to improve economy. In mountainous, urban, or off-road scenarios, the neutral coasting function can be disabled. Furthermore, in mountainous scenarios, the brake gear hold function is activated at a lower speed threshold, allowing gear hold activation only in lower gears to fully utilize engine braking during downshifts. In urban scenarios, the brake gear hold function is activated at a higher speed threshold, allowing gear hold activation in higher gears, reducing shift frequency and improving driving smoothness. This adjustment logic takes into account the performance requirements of the vehicle under specific operating conditions and aims to optimize gear control to suit the current driving conditions.

[0056] It should be noted that the adjustment of the gear shift strategy is dynamic and can be updated in real time as the target operating conditions change. This means that even if the vehicle encounters a change in operating conditions during driving, the gear shift strategy can be quickly adjusted to ensure that the vehicle can achieve optimal economic performance and driving comfort under any conditions. By adjusting the gear shift strategy according to the target operating conditions, the embodiment of the present invention can enable the vehicle to exhibit higher economic performance than the initial gear shift strategy under specific conditions. For example, under conditions requiring high torque, the adjusted target gear shift strategy can provide more sufficient power support; and in scenarios requiring high energy efficiency, it can significantly improve fuel economy and reduce unnecessary fuel consumption.

[0057] In an embodiment of the present invention, the above-mentioned gear shifting strategy adjustment based on road conditions not only improves the intelligence level of the vehicle, but also provides the driver with a more personalized driving experience. It can automatically optimize the gear shifting decision according to the actual road conditions, avoiding the need for frequent manual intervention by the driver, while also taking into account the driving habits and needs of different drivers under different working conditions. In summary, by understanding and adapting to the characteristics of the target working conditions, the initial gear shifting strategy is adjusted in a targeted manner to generate a new target gear shifting strategy. The above process significantly improves the gear shifting control accuracy of the vehicle under specific working conditions, not only optimizes the economic performance, but also takes into account driving comfort. It is the core step in realizing intelligent and personalized control of vehicle driving in the present invention. By dynamically adjusting the gear shifting strategy, the present invention can provide the driver with the best driving experience while reducing vehicle maintenance and operating costs.

[0058] In step S110 , a gear shift operation is performed on the gear position according to the target gear shift strategy, and the vehicle is controlled to travel on a road of the target working condition according to the gear position after the gear shift operation is performed.

[0059] In the technical solution provided in the above step S110 of the present invention, after the initial gear shifting strategy is adjusted based on the target working condition to obtain the target gear shifting strategy, the gear shifting operation of the vehicle can be performed according to the target gear shifting strategy, and the vehicle can be controlled to travel on the road of the target working condition according to the gear after the gear shifting operation is performed.

[0060] In this embodiment, precise gear shifting is performed according to the target shift strategy, thereby controlling the vehicle to operate in the most appropriate manner within the current target operating conditions. These steps not only consolidate the results of the previous operating condition adaptability analysis but also directly impact the driving experience and vehicle performance.

[0061] Optionally, the generated target shift strategy can be used to guide the vehicle in making specific gear adjustments. For example, in high-speed driving conditions, the economy mode base shift point speed can be modified to improve efficiency.

[0062] It should be noted that the shifting operation in this embodiment of the present invention is dynamic, meaning it can be adjusted in real time as vehicle driving conditions change. This means that even if driving conditions change during driving, the system can quickly respond and execute new shifting decisions, ensuring that the gear position always meets the needs of the current driving environment, thereby achieving smooth and efficient driving.

[0063] Optionally, after a gear shift, the vehicle's driving behavior can be further controlled based on the new gear. For example, when shifting to a higher gear, the vehicle might reduce fuel supply to lower engine speed; while in a lower gear, the system might increase throttle response or maintain higher rpm to provide greater torque output. This refined driving control ensures optimal vehicle economical performance under varying road conditions.

[0064] In an embodiment of the present invention, by accurately executing the target shift strategy, not only can the vehicle's fuel economy and economic performance be improved, but the driving experience can also be significantly improved. For example, in urban congestion, timely gear retention and neutral coasting functions can reduce the frequency of gear shifts, reduce transmission wear, and also reduce the ride discomfort caused by frequent acceleration and deceleration. The above method further demonstrates the vehicle's intelligence level. It shows that the vehicle can not only automatically identify road conditions, but also autonomously adjust the shift strategy based on the identification results and execute the shift operation without the driver's manual intervention, thereby reducing the driving burden and improving the overall shift efficiency.

[0065] In steps S102 to S110 of the present application, if vehicle control is required, vehicle status information can be acquired in real time while the vehicle is traveling. A match between the status information and a preset status indicator in a candidate operating condition set can be determined. Based on the matching result, the target operating condition for the road the vehicle is currently traveling on is determined from the candidate operating condition set, and the vehicle's initial shift strategy is adjusted based on the target operating condition to obtain an adjusted target shift strategy. The vehicle's gear can be shifted according to the target shift strategy, and the vehicle can be controlled to travel on the road in the target operating condition according to the gear selected after the shift operation. In this embodiment, by acquiring the vehicle's status information in real time during driving and matching it with a preset candidate operating condition set, dynamic operating condition identification and intelligent adjustment of the shift strategy are achieved for the vehicle's driving conditions. In other words, through real-time operating condition identification and dynamic adjustment of the shift strategy, the technical problem of low gear control accuracy is resolved, achieving the technical effect of improving gear control accuracy.

[0066] The above method of this embodiment is further introduced below.

[0067] As an optional implementation method, step S106, based on the matching results, determines the target operating condition that the road is currently in from the candidate operating condition set, including: obtaining preset conditions of the candidate operating conditions in the candidate operating condition set, wherein the preset conditions include preset state indicators, the preset state indicators correspond to the state information, and the preset conditions correspond one-to-one to the candidate operating conditions; the candidate operating conditions are concentrated, and the candidate operating conditions corresponding to the preset conditions whose matching results are state information that meets the preset state indicators are determined as the target operating conditions.

[0068] In this embodiment, when determining the vehicle's current target operating condition from a set of candidate operating conditions based on the matching results, preset conditions for the candidate operating conditions in the set of candidate operating conditions can be obtained. The candidate operating conditions in the set of candidate operating conditions whose matching results show that their state information satisfies a preset state indicator are determined as the target operating conditions. The preset conditions may include a preset state indicator. The preset state indicator may correspond to the state information. The preset conditions correspond one-to-one with the candidate operating conditions.

[0069] Optionally, the implementation aims to accurately determine the target operating condition of the current road from the candidate operating condition set through clear logic and conditional judgment. The above process is based on the previous state information collection and the matching results with the preset state indicators of the candidate operating conditions.

[0070] Optionally, preset conditions are defined for each candidate operating condition and are a series of rules or standards used to identify whether the road operating condition exists. The preset conditions include specific preset state indicators, such as vehicle speed, slope, turning radius, etc. The above preset conditions correspond to the vehicle state information and are used to determine whether the vehicle is in this operating condition. The setting of preset conditions is based on an in-depth understanding of the vehicle driving characteristics under different road conditions, ensuring the accuracy and reliability of operating condition identification. There is a one-to-one correspondence between preset conditions and candidate operating conditions, which means that each candidate operating condition has a specific set of preset conditions. For example, highway conditions may correspond to a higher speed range, a smaller slope, and a larger turning radius; while the preset conditions for urban road conditions may include lower speeds, frequent stops, and shorter driving distances. The above correspondence provides clear guidance for operating condition identification, which can purposefully find the operating condition type that best matches the current state information.

[0071] Optionally, the matching results can be used to filter which candidate operating conditions meet the preset conditions for the current vehicle state. A condition is considered a match only if the state information fully meets the preset state indicators for that condition. Based on this screening process, the candidate conditions that successfully match are selected from the candidate set.

[0072] It's important to note that the target operating condition isn't static, but rather is continuously adjusted as the vehicle's driving state changes. This means that if the vehicle's state information changes (for example, when the vehicle switches from a highway to an urban road), a rematch check can be performed, and the target operating condition can be confirmed based on the latest matching results, ensuring the vehicle always adapts to the current driving environment.

[0073] In this embodiment of the present invention, the above-described method demonstrates the intelligent decision-making process of a vehicle control system. This process automatically identifies the most appropriate operating condition by comparing real-time status information with pre-set operating conditions. This process not only reduces the possibility of human error but also enables the vehicle to automatically adjust its operating mode under various complex driving conditions, thereby improving overall driving safety, comfort, and economy.

[0074] In summary, by matching preset conditions with state information, accurate identification of the vehicle's current target operating condition is achieved. This process, which relies on detailed preset state indicators, the correspondence between operating conditions and conditions, and the ability to dynamically adjust, is an integral component of the adaptive adjustment mechanism for the vehicle's shift control strategy. This approach not only enhances the vehicle's adaptability to complex road conditions but also further advances the intelligent development of vehicle control systems, providing drivers with a more convenient, efficient, and safer driving experience.

[0075] As an optional embodiment, the candidate operating condition includes a highway operating condition, the state information includes: vehicle speed information, slope information, turning radius information, mileage information, and vehicle state, and the preset state indicators include: a first vehicle speed threshold, a first turning radius threshold, a first slope threshold, a first mileage threshold, and a stationary state. In response to the state information satisfying the following first preset condition, the target operating condition is determined to be a highway operating condition: the vehicle speed information is greater than the first vehicle speed threshold, the slope information is less than or equal to the first slope threshold, the turning radius information is greater than the first turning radius threshold, and the mileage information is greater than or equal to the first mileage threshold; in response to the state information satisfying the following exit condition for the highway operating condition, and the duration for which the state information satisfies the exit condition for the highway operating condition satisfies a first duration threshold, the target operating condition is determined to be a target operating condition other than the highway operating condition: the slope information is greater than or equal to the first slope threshold, and the turning radius information is less than or equal to the first turning radius threshold; or the vehicle speed information is less than or equal to the first vehicle speed threshold, and the vehicle state transitions from a driving state to a stationary state.

[0076] This embodiment describes how to determine and confirm highway operating conditions based on status information and preset status indicators, as well as how to handle exiting highway operating conditions. The above process involves real-time vehicle status monitoring, data analysis, and intelligent judgment of operating condition identification.

[0077] Optionally, vehicle speed is the primary condition for judging the highway working condition, which is greater than a preset first vehicle speed threshold. This threshold is usually much higher than the average vehicle speed on urban or mountainous roads, for example, above 100 km / h. The slope of a highway is generally low, so the slope information is required to be less than or equal to the preset first slope threshold, which helps to avoid erroneous identification of steep or undulating sections as highway working conditions. The turning radius of a highway is much larger than that of an urban road, so the turning radius information needs to be greater than the preset first turning radius threshold. The first turning radius threshold can be set to exclude sharp turns in the city. In order to avoid accidental road conditions being misjudged as highway working conditions, it is also necessary to confirm that the mileage traveled within a certain period of time is greater than or equal to the preset first mileage threshold.

[0078] Optionally, when the vehicle's real-time status information meets each of the aforementioned first pre-set conditions, the vehicle is determined to be operating in a highway condition. This determination, based on a comprehensive consideration of the vehicle's real-time status, ensures the accuracy and reliability of the operating condition identification, thus providing a solid foundation for further shift strategy adjustments.

[0079] Alternatively, if the slope exceeds a preset exit slope threshold and the turning radius is less than or equal to the exit turning radius threshold, this indicates the vehicle may have entered a more complex or rugged road section, no longer meeting the requirements for expressway operation. A decrease in speed below the exit speed threshold, combined with a transition from driving to stationary status, is also a clear signal to exit expressway operation.

[0080] Optionally, in addition to satisfying the aforementioned exit conditions, it may also be necessary to confirm that the duration of the aforementioned state change has reached a preset first duration threshold. The first duration threshold is set to avoid misjudging the operating condition exit due to brief changes in conditions and to ensure the stability of operating condition transition judgments. For example, if a vehicle on a highway slows down due to temporary traffic conditions ahead and immediately exits the high-speed operating condition, this may result in frequent changes in shift strategy, affecting the driving experience and vehicle performance. Therefore, the first duration threshold is a safeguard mechanism to ensure the authenticity and persistence of operating condition recognition changes.

[0081] In this embodiment of the present invention, by precisely setting the first preset condition and exit condition, combined with the confirmation of the first duration threshold, it is possible to accurately identify highway road conditions in complex and changing driving environments and promptly adjust the shift strategy. This intelligent judgment capability not only improves the vehicle's fuel economy and driving comfort at highway speeds, but also enables rapid response to subtle changes in road conditions, ensuring that the vehicle maintains appropriate performance even when transitioning to other operating conditions. This entire process demonstrates the vehicle control system's high level of intelligence in understanding and adapting to the driving environment, a key component in improving the overall vehicle driving experience and performance.

[0082] As an optional embodiment, the candidate operating condition includes a mountainous road condition, the status information includes: slope information, slope duration, turning radius information, number of turns and mileage information, and the preset status indicators include: a second slope threshold, a third slope threshold, a first slope duration, a second turning radius threshold, a third turning radius threshold, a number of turns threshold and a second mileage threshold. In response to the status information satisfying the following second preset condition, the target operating condition is determined to be a mountainous road condition: the slope information is greater than the second slope threshold, and the slope duration is greater than or equal to the first slope duration threshold; or, the turning radius information is less than the second turning radius threshold, and the number of turns is greater than the turning number threshold; in response to the status information satisfying the following exit condition for the mountainous road condition, the target operating condition is determined to be a target operating condition other than the mountainous road condition: the slope information is less than or equal to the third slope threshold, the turning radius information is greater than or equal to the third turning radius threshold, and the mileage information is greater than or equal to the second mileage threshold.

[0083] This embodiment describes how to intelligently identify and confirm whether the vehicle is currently traveling on a mountainous road based on a comparison of vehicle status information with preset status indicators for a specific operating condition, and how to exit this operating condition in a timely manner based on the changing status information.

[0084] Optionally, mountain road condition identification relies primarily on slope information, which must be greater than a preset second slope threshold, and the slope duration must be greater than or equal to a first slope duration threshold. This threshold setting takes into account the universality and continuity of slope changes on mountain roads, ensuring that mountain road conditions are only determined when a long, continuous slope is encountered. Another way to identify mountain road conditions is based on turning radius information and the number of turns. When the turning radius information is less than the second turning radius threshold, and the number of turns exceeds the preset turning threshold, this indicates that the vehicle is frequently traversing winding, narrow roads, and under these conditions, it should also be determined to be mountain road conditions.

[0085] Alternatively, the target driving condition can be identified as a mountainous road condition by satisfying either of the above two conditions. This logic takes into account two typical characteristics of mountain roads: continuous slope changes and frequent curves, ensuring comprehensive and accurate driving condition identification.

[0086] Optionally, if the slope information drops to less than or equal to a third slope threshold and the turning radius information is greater than or equal to the third turning radius threshold, this indicates that the vehicle may have left the continuous slope and narrow curves of mountain roads and entered a relatively flat and straight road area. To ensure that the vehicle has truly left the area affected by mountain road conditions, the mileage information must be greater than or equal to a preset second mileage threshold. This threshold prevents interference with condition recognition caused by brief driving on roads with similar mountainous conditions.

[0087] Alternatively, unlike entry conditions, the satisfaction of exit conditions can immediately determine that the target operating condition has transitioned to a condition other than mountainous road conditions, without requiring an additional time threshold. This is because once a vehicle exits a mountainous road, the change in state information is often significant and immediate, eliminating the need to consider the duration required for entry conditions to eliminate the influence of accidental factors.

[0088] In the embodiment of the present invention, the identification and exit strategy of mountain road conditions demonstrates the intelligent decision-making ability of the present invention in handling complex terrain conditions. By setting specific status information thresholds and logical judgments, the system can accurately determine when the vehicle enters and leaves mountain road conditions. This identification strategy ensures the timeliness and rationality of the adjustment of the shift strategy, so that when the vehicle is driving in the mountainous area, it can effectively cope with the challenges brought by slopes and curves, ensuring power and safety; and after leaving the mountainous area, it can quickly adapt to the new road conditions and revise the shift strategy to achieve better fuel economy and driving comfort. The entire process embodies the sensitive capture and intelligent response to vehicle status information, and is an important part of improving the level of vehicle driving intelligence.

[0089] As an optional embodiment, the candidate operating condition includes an urban road operating condition, the status information includes: vehicle speed information, vehicle status and mileage information, and the preset status indicators include: a second vehicle speed threshold, a stationary state, a driving state, a third mileage threshold and a fourth mileage threshold. In response to the status information satisfying the following third preset condition, the target operating condition is determined to be the urban road operating condition: the vehicle speed information is less than or equal to the second vehicle speed threshold, and the number of times the vehicle state is converted from the driving state to the stationary state exceeds the first number threshold, and the mileage information after the vehicle state is converted from the stationary state to the driving state is less than the third mileage threshold; in response to the status information satisfying the following exit condition for the urban road operating condition, the target operating condition is determined to be a target operating condition other than the urban road condition: the mileage information after the vehicle state is converted from the stationary state to the driving state is greater than or equal to the fourth mileage threshold.

[0090] In this embodiment, the recognition logic for urban road conditions is explained. Based on the vehicle's status information and preset status indicators, it further refines how to determine whether the vehicle is in an urban road condition and how to judge the timing of exiting the urban road condition.

[0091] Optionally, identification of urban road conditions is primarily based on vehicle speed information, which must be less than or equal to a second speed threshold. This second speed threshold reflects the common characteristics of urban roads, such as traffic congestion, frequent red and green lights, and slower vehicle speeds. Urban road condition identification also considers whether the number of times the vehicle transitions from driving to stationary exceeds a first threshold and whether the mileage after the vehicle transitions from stationary to driving is less than a third threshold.

[0092] Alternatively, if the vehicle speed meets the low-speed criteria, and the vehicle experiences frequent stop-and-start traffic, along with short trips after each resumption from a standstill, the system will identify the vehicle's current operating condition as urban. This recognition strategy effectively captures the typical characteristics of urban traffic environments, ensuring accurate and reliable identification of operating conditions.

[0093] Optionally, determining whether the vehicle has exited the urban road condition is primarily based on whether the mileage information after the vehicle's state transitions from a stationary state to a driving state is greater than or equal to a fourth mileage threshold. This threshold setting is a reverse consideration of the characteristics of the urban road condition, meaning that after the vehicle has continuously traveled a certain distance, it indicates that it may have exited the frequent stop-and-start conditions of urban roads. Once the vehicle's mileage information reaches the fourth mileage threshold for exiting the urban road condition, it can be immediately confirmed that the vehicle has exited the urban road condition, transitioning to other types of condition identification and shift strategy adjustment. The above logic design takes into account the significant differences in driving characteristics between urban and non-urban roads, ensuring the timeliness and accuracy of condition transitions and avoiding unnecessary confusion of shift strategies between different conditions.

[0094] In this embodiment of the present invention, the identification and exit strategies for urban road conditions fully demonstrate the vehicle control system's profound understanding of the urban traffic environment. By monitoring vehicle speed, the frequency of vehicle state transitions, and the short distance traveled after each transition, it can intelligently determine whether the vehicle is in urban road conditions and adjust the shift strategy and related functions accordingly. For example, in urban road conditions, the system may reduce the use of the neutral coasting function to avoid unnecessary safety hazards in frequent parking environments. Furthermore, considering the need for driving smoothness, the brake gear hold function may be activated earlier at higher speeds to reduce the number of gear shifts and improve driving comfort.

[0095] As an optional embodiment, the candidate operating condition includes an off-road operating condition, the state information includes vehicle speed information, acceleration information, and driving resistance information, and the preset state indicators include: a third vehicle speed threshold, a first acceleration threshold, and a first driving resistance threshold. In response to the state information satisfying the following fourth threshold condition, the target operating condition is determined to be the off-road operating condition: the vehicle speed information is less than or equal to the third vehicle speed threshold, and the difference information between the acceleration information and the gravitational acceleration is greater than the first acceleration threshold, and the number of times the difference information exceeds the first acceleration threshold is greater than or equal to a second number threshold; or the vehicle speed information is less than or equal to the third vehicle speed threshold, and the driving resistance information is greater than or equal to the first driving resistance threshold; in response to the state information satisfying the following exit condition for the off-road operating condition, and the duration for which the state information satisfies the exit condition for the off-road operating condition satisfies a second duration threshold, the target operating condition is determined to be a target operating condition other than the off-road condition: in response to the vehicle speed information being greater than the third vehicle speed threshold, or the difference information being less than the first acceleration threshold, or the number of times the difference information exceeds the first acceleration threshold is less than a second number threshold, or the driving resistance information is less than the first driving resistance threshold.

[0096] In this embodiment, by comparing vehicle status information with preset status indicators, it is possible to intelligently determine whether the vehicle is in an off-road operating condition and when to exit such an operating condition. Off-road operating conditions include, but are not limited to, off-road driving, construction sites, and other complex terrain where the vehicle may experience extreme driving conditions.

[0097] Optionally, the identification of off-road conditions is first based on vehicle speed information, which is required to be lower than or equal to a third vehicle speed threshold. The third vehicle speed threshold reflects the characteristic that vehicles do not usually travel at high speeds in off-road environments. By comparing the acceleration information with the difference information of the gravitational acceleration (9.8m / s^2), it is determined whether it is greater than the first acceleration threshold, and whether this situation continues to exceed the second speed threshold. This reflects the bumps or vibrations caused by uneven terrain that the vehicle may encounter in off-road environments. Another basis for identifying off-road conditions is that the driving resistance information is greater than or equal to the first driving resistance threshold, which indicates that the vehicle may be traveling on high-resistance terrain such as sand, mud or snow.

[0098] Alternatively, the system determines that the vehicle is in an off-road condition when the vehicle's speed, acceleration, or driving resistance information meets any of the above conditions. This logic design takes into account several typical characteristics of off-road environments, including low vehicle speeds, frequent bumps, and high driving resistance, ensuring comprehensive and accurate identification of off-road conditions.

[0099] Optionally, if the vehicle speed exceeds a third speed threshold, this may indicate that the vehicle has entered a relatively flat road surface or one suitable for high-speed driving. If the difference between the acceleration and the acceleration due to gravity falls below a first acceleration threshold, or if the difference exceeds the first acceleration threshold for fewer times than a second threshold, this indicates that the vehicle has experienced less bumps or vibrations and may have exited the off-road environment. If the driving resistance falls below the first driving resistance threshold, this further confirms that the vehicle is no longer facing the challenges of high-resistance terrain.

[0100] Optionally, to ensure the stability of off-road mode exit determination, it may also be confirmed that the exit condition has been met for longer than a preset second duration threshold. This second duration threshold prevents misjudgment of mode exit due to a brief improvement in conditions, ensuring that the mode transition is only formally initiated after the vehicle has consistently exited the off-road environment and the status information steadily indicates improvement.

[0101] As an optional embodiment, the candidate operating conditions include expressway operating conditions, mountainous road conditions, urban road conditions, non-road operating conditions and national highway road conditions. The method also includes: in response to the preset conditions of expressway operating conditions, mountainous road conditions, urban road conditions and non-road operating conditions not being met, determining the target operating condition as a national highway road condition; in response to the status information meeting the following exit conditions of the national highway road condition, determining the target operating condition as a target operating condition other than the national highway road condition: the status information meets any preset condition of the preset conditions of the expressway operating conditions, mountainous road conditions, urban road conditions and non-road conditions.

[0102] This embodiment illustrates the logic for determining the national highway operating condition by a process of elimination from a set of candidate operating conditions. This logic compares vehicle status information with pre-defined status indicators, confirming whether the vehicle is in a national highway operating condition by negating the existence of other specific operating conditions.

[0103] Optionally, when the vehicle's status information is continuously monitored and analyzed, it can be determined whether the vehicle is operating in a highway, mountainous, urban, or off-road condition. This process involves a comprehensive evaluation of various status information, including vehicle speed, slope, turning radius, mileage, and acceleration, and comparison with pre-set status indicators for each of these conditions.

[0104] Optionally, if after the above comparative analysis, the status information fails to meet any preset conditions of highway conditions, mountain road conditions, urban road conditions, or non-road conditions, that is, the vehicle status information does not match the characteristics of these specific conditions, then the system will respond to this exclusion result and determine that the target condition is a national highway road condition.

[0105] Optionally, national highway road conditions may include a certain degree of speed changes, slopes, curves and driving resistance, but the degree of these characteristics is not sufficient to meet the identification conditions of other more specific conditions. For example, the vehicle speed may be higher than that of urban road conditions, but lower than that of highway conditions; the turning radius is larger than that of urban roads, but not necessarily up to the standards of highways; the slope and driving resistance are also smaller than those of non-road conditions, but may be more obvious than those of urban roads and highways. By systematically excluding other candidate conditions, when the identification conditions of the above-mentioned specific conditions are not met, the national highway road condition is confirmed as the default condition. This also means that the national highway road condition is a broad, default condition type that covers driving environments that cannot be clearly classified as highway, mountainous, urban or non-road conditions.

[0106] Optionally, the flexibility of this logic design lies in the inclusion of national highway conditions as a residual condition, encompassing various road sections in driving scenarios that are difficult to clearly categorize, such as connecting roads between cities and highways and relatively straight suburban roads. This design ensures that the vehicle control system can fully and accurately identify operating conditions in complex and changing driving environments, avoiding decision-making errors caused by incompletely defined operating condition types.

[0107] As an optional embodiment, step S108 adjusts the initial gear shifting strategy of the vehicle based on the target operating condition to obtain an adjusted target gear shifting strategy, including: based on the target operating condition, adjusting at least the initial shift timing and initial speed in the initial gear shifting strategy to obtain the target gear shifting strategy, wherein the initial speed is the basic shift point speed of the economic mode of the vehicle to be adjusted.

[0108] In this embodiment, when adjusting the initial shift strategy of the vehicle based on the target operating condition to obtain the target shift strategy, at least the initial shift timing and initial speed of the initial shift strategy can be adjusted based on the target operating condition to obtain the target shift strategy. The initial speed is the basic shift point speed of the vehicle in the economy mode to be adjusted.

[0109] Optionally, this embodiment illustrates how to adjust the vehicle's initial shift strategy based on the determined target operating conditions to optimize driving experience, fuel economy, and vehicle performance. The above process involves adjusting the shift timing and the basic shift point speed in the economy mode.

[0110] Alternatively, the vehicle's priorities for performance, fuel efficiency, and driving experience may vary depending on the vehicle's operating conditions. For example, on highways, the focus is on high-speed stability, fuel economy, and a smooth ride; on mountainous roads, the emphasis is on providing sufficient climbing torque and vehicle controllability. Therefore, adjusting the shift strategy based on the target operating conditions ensures optimal shifting behavior in various road conditions, thereby improving overall performance.

[0111] Optionally, shift timing refers to the specific point in time when the vehicle shifts up or down, and is a key parameter in the shift strategy. When adjusting the shift strategy based on the target operating condition, the shift timing is adjusted based on the characteristics of the target operating condition. For example, when driving on a highway, to improve fuel economy, upshifting can be advanced, allowing the vehicle to travel in a higher gear at a lower speed, reducing engine load.

[0112] Optionally, the initial speed refers to the basic shift point speed of the economy mode before or after the gear shift. By adjusting the initial speed parameter, the performance during the gear shift process can be further optimized. Based on the target operating conditions, the target basic shift point speed of the economy mode before or after the gear shift can be adjusted. For example, under highway conditions, the upshift system tends to reduce the speed after the gear shift to reduce fuel consumption. For the downshift system, the speed before and after the downshift will tend to be reduced to reduce downshifts, improve high gear utilization, and improve transmission efficiency and fuel economy. Under mountainous road conditions, the speed before upshifting may need to be appropriately increased to ensure the continuity of torque after the gear shift.

[0113] Optionally, a speed correction table can be introduced to adjust the initial speed after upshifting or downshifting based on the current gear position and target operating conditions. For example, in highway scenarios, the target shift strategy can be used to adjust the base shift point speed in economy mode. In mountainous, urban, or off-road scenarios, the neutral coasting function can be disabled. Furthermore, in mountainous scenarios, the brake gear hold function activates at a lower speed threshold, allowing gear hold to be activated only in lower gears, fully utilizing engine braking during downshifts. In urban scenarios, the brake gear hold function activates at a higher speed threshold, allowing gear hold to be activated in higher gears, reducing shift frequency and improving driving smoothness.

[0114] As an optional embodiment, the initial speed in the initial gear shifting strategy is adjusted based on the target operating condition, including: in response to the gear shifting operation to be executed being an upshifting operation, adjusting the initial speed after the upshifting operation is executed based on the target operating condition, wherein the adjusted initial speed is less than the initial speed before the adjustment; in response to the gear shifting operation to be executed being a downshifting operation, adjusting the initial speed before the downshifting operation is executed based on the target operating condition, wherein the adjusted initial speed is less than the initial speed before the adjustment; in response to the downshifting operation being executed, adjusting the initial speed after the downshifting operation is executed based on the target operating condition, wherein the adjusted initial speed is less than the initial speed before the adjustment; based on the target operating condition, adjusting the initial gear shifting strategy of the vehicle to obtain an adjusted target gear shifting strategy, including: in response to the target operating condition being a non-road operating condition, determining the preset gear shifting strategy corresponding to the non-road operating condition as the target gear shifting strategy.

[0115] In this embodiment, during the process of adjusting the initial speed in the initial shift strategy based on the target operating condition, if the shift operation to be executed is an upshift operation, the initial speed after the upshift operation can be adjusted based on the target operating condition, so that the adjusted initial speed is less than the initial speed before the adjustment. If the shift operation to be executed is a downshift operation, the initial speed before the downshift operation can be adjusted based on the target operating condition, so that the adjusted initial speed is less than the initial shift speed before the adjustment. After the above-mentioned downshift operation is executed, the initial speed after the downshift operation can be adjusted so that the adjusted initial speed is less than the initial shift speed before the adjustment. If the target operating condition is an off-road operating condition, the preset shift operation corresponding to the off-road operating condition can be determined as the target shift strategy.

[0116] Optionally, this embodiment describes how to adjust the initial speed in the initial shift strategy of the vehicle based on the target operating condition, and how to directly apply the preset shift strategy under specific operating conditions (such as non-road conditions).

[0117] Optionally, when the vehicle is about to perform an upshift operation, the initial speed after the upshift can be adjusted based on the target operating conditions, so that the adjusted initial speed is less than the initial speed before the adjustment. The purpose of the above adjustment is to adapt to the fuel economy and driving smoothness requirements under different operating conditions. This operation is aimed at highway operating conditions, in order to achieve early upshifting to reduce the engine speed, thereby reducing fuel consumption and improving fuel economy. When the vehicle needs to perform a downshift operation, the initial speed before the downshift can also be adjusted based on the target operating conditions, so that the adjusted initial speed is less than the initial speed before the adjustment. At the same time, the initial speed after the downshift is also adjusted to ensure that the adjusted speed is less than the speed before the adjustment. This operation is aimed at highway operating conditions, in order to reduce downshifting, make full use of high gears, improve transmission efficiency and reduce fuel consumption.

[0118] Optionally, when the target operating condition is identified as an off-road operating condition, a preset shift strategy corresponding to the off-road operating condition is directly determined as the target shift strategy. The preset strategy may include specific shift logic and parameter settings for off-road environments.

[0119] The technical solutions of the embodiments of the present invention are described below with reference to preferred implementation methods.

[0120] Currently, existing automated mechanical transmissions (AMTs) are developed from manual transmissions (MTs) by adding various sensors, transmission control units, electronically controlled shift selectors, and clutch actuators. Compared to other automatic transmission solutions, AMTs offer the advantages of low cost and high transmission efficiency. The use of pneumatic shift actuators effectively prevents environmental pollution from oil leaks from hydraulic actuators. Furthermore, the control medium is air, resulting in lower actuator costs. Therefore, the current mainstream AMTs primarily utilize electronically controlled pneumatic shift actuators. During the automatic transmission shift process, the TCU controls the shift solenoid valve to open the air circuit, directing the working air into the actuator to move the cylinder piston, which in turn drives the connected shift fork, pushing or shifting the shift sleeve into the target gear position.

[0121] With the popularization of AMT transmissions, drivers' requirements for vehicle comfort and fuel economy are gradually increasing, and drivers' requirements for the intelligence level of AMT are also getting higher and higher. On the one hand, comfort and economy are closely related to whether the vehicle can select the correct gear. On the other hand, intelligence is reflected in the ability to automatically adjust the shift points and functional modes according to different road conditions without the need for driver intervention. Both are reflected in the adaptive selection of reasonable gears according to different scenarios. Therefore, to decide the correct gear, it is necessary to accurately identify the vehicle's driving conditions, automatically correct the basic shift points according to the current driving conditions, and automatically adjust functions such as neutral coasting and gear holding, and select the gear and functional status suitable for the current working conditions, so as to achieve the appropriate economy effect.

[0122] The present invention proposes a method for road condition scenario recognition and shift decision correction. This method identifies the current driving road condition scenario and automatically corrects the basic shift points based on this scenario. It also automatically adjusts functions such as neutral coasting and gear hold, selecting the gear and functional state that best suits the current driving conditions, thereby achieving optimal economic efficiency. Furthermore, the automatic correction and adjustment functions can reduce calibration work during product development, improving product development efficiency. This solves the technical problem of low gear control accuracy and achieves the technical effect of improving gear control accuracy.

[0123] The following is a further introduction to the embodiments of the present invention.

[0124] In this embodiment, a vehicle speed signal, a slope estimation signal, a turning radius signal, a vertical ground acceleration signal, a driving resistance signal, and a braking signal are obtained through a sensor and a controller area network (CAN) communication module. Based on this, a road condition scene recognition module identifies the current road condition of the vehicle and outputs a road condition signal. Then, an economy mode basic upshift point module, an economy mode pre-downshift basic shift point module, an economy mode post-downshift basic shift point module, a non-road mode basic upshift point module, a non-road mode pre-downshift basic shift point module, a non-road mode post-downshift basic shift point module, a neutral coasting function module, and a brake gear holding function module receive the road condition signal, and modify the shift point according to the road condition signal to determine the confirmation time for activating the neutral coasting function and the gear holding function. Trigger vehicle speed, and give a road condition scene recognition method, a highway road condition recognition method, a mountain road condition recognition method, an urban road condition recognition method, a shift decision correction method based on the driver's road condition scene recognition, thereby deriving a shift decision correction method based on road condition scene recognition. This method aims to identify the current driving road condition scene, and automatically correct the basic shift point based on the road condition scene state, automatically adjust functions such as neutral coasting and gear holding, select the shift point and functional state that best suits the current working condition, and thus select the best shift time and gear, so as to achieve the best economic effect, and the automatic correction and automatic adjustment functions can also reduce the calibration work in the product development process and improve product development efficiency.

[0125] Figure 2 FIG. 1 is a flow chart of a method for identifying road conditions and correcting gear shift decisions according to an embodiment of the present invention. Figure 2 As shown, the method may include the following steps:

[0126] Step S201: Obtain vehicle speed signal, slope estimation signal, turning radius signal, vertical ground acceleration signal, driving resistance signal, and brake signal from the CAN bus.

[0127] In this embodiment, the sensor and the CAN communication module obtain the vehicle speed signal, the slope estimation signal, the turning radius signal, the vertical ground acceleration signal, the driving resistance signal, and the brake signal from the CAN bus.

[0128] Step S202 , based on the entry and exit conditions of the road condition identification, identify the highway condition, mountain road condition, urban road condition, non-road condition and national highway road condition, and output a status signal representing the road condition.

[0129] In this embodiment, a road condition scene recognition method includes methods for identifying highway conditions, mountain road conditions, urban road conditions, non-road conditions and national highway road conditions. Whenever the entry conditions of an identified road condition are met, a status signal representing the road condition will be output.

[0130] Optionally, the conditions for entering the highway working condition are: the vehicle speed exceeds the vehicle speed threshold 1, and the absolute value of the slope does not exceed the slope threshold ①, and the turning radius is greater than the turning radius threshold I, and the mileage A calculated by integrating the absolute value of the vehicle speed over time is not less than the set mileage threshold a. If all of the above conditions are met, it is recognized that the vehicle is in the highway working condition at this time; the mileage obtained by time integration based on the absolute value of the vehicle speed is reset and maintained at 0 when the exit condition for high-speed working condition identification is met, or it is reset to 0 and the integral calculation is restarted when other working condition entry conditions are met.

[0139] Step S203: modifying the gear shift decision based on the road condition scene recognition.

[0140] In this embodiment, the vehicle's shift strategy is adjusted based on the identified road condition signal to adapt to the current operating conditions. This ensures that shift decisions can be made in a timely manner based on changing road conditions, thereby improving the vehicle's fuel economy, power, and driving comfort.

[0141] Step S204 , based on the state signal of the road working condition, the basic upshift point of the economic mode, the basic shift point before downshifting in the economic mode, and the basic shift point after downshifting in the economic mode are corrected for the highway working condition.

[0142] In this embodiment, Table 1 is a corresponding table of speed correction after upshifting according to an embodiment of the present invention. As shown in Table 1, for the speed after upshifting, the road operating condition state signal is input into the basic upshift point module of the economic mode. When the road condition is a highway operating condition and the current gear is not lower than the set gear N, a speed correction amount table after upshifting 1 gear is set. The input of the table is the current gear, and the output is the speed correction amount after upshifting 1 gear. The speed correction amount is subtracted from the basic shift point of the economic mode to appropriately reduce the speed after upshifting.

[0143] Table 1 Speed ​​correction correspondence table after upshifting

[0144] Current gear / num N N+1 N+… N+i Speed ​​correction after upshifting / rpm n n1 … ni

[0145] Step S205 , based on the state signal of the road working condition, for the non-road working condition, the speed after upshifting, the speed before downshifting, and the speed after downshifting dedicated to the non-road mode are used.

[0146] In this embodiment, for the speed before downshifting, the road condition status signal is input into the basic shift point module before downshifting in the economic mode. When the road condition is a highway condition and the current gear is not lower than the set gear N, a table of speed correction values ​​before downshifting for each gear higher than the gear is set. The input of the table is the current gear, and the output is the speed correction value before downshifting by 1 gear. The speed correction value is subtracted from the basic shift point before downshifting in the economic mode to appropriately reduce the speed before downshifting.

[0147] Optionally, for the speed after downshifting, the road condition status signal is input into the basic shift point module after downshifting in economic mode. When the road condition is a highway condition and the current gear is not lower than the set gear N, a table of speed correction amounts after downshifting for each gear higher than the gear is set. The input of the table is the current gear, and the output is the speed correction amount after downshifting by 1 gear. The speed correction amount is subtracted from the basic shift point after downshifting in economic mode to appropriately reduce the speed after downshifting.

[0148] Optionally, when the road condition is non-road, the speed after upshifting, the speed before downshifting, and the speed after downshifting dedicated to the non-road mode are switched to use.

[0149] Step S206, based on the status signal of the road condition, the confirmation time of the neutral coasting function is distinguished. The time for highway conditions is shorter than that for national roads; the neutral coasting function is disabled on mountain roads, urban roads, and non-roads.

[0150] In this embodiment, the road condition signal is input to the neutral coasting function module. The confirmation time required to meet the neutral coasting function requirement varies depending on the road condition. The confirmation time for highway conditions is shorter than that for national roads, and the former can be set to 1 / 4 of the latter. The neutral coasting function is disabled for mountainous, urban, or non-road conditions.

[0151] Step S207 , based on the state signal of the road working condition, the brake gear hold is activated at a lower vehicle speed and a lower gear on a mountain road, and the brake gear hold is activated at a higher vehicle speed and a higher gear on an urban road.

[0152] In this embodiment, the road condition signal is input into the brake gear hold function module. On mountainous roads, the brake gear hold function is activated at a lower speed threshold, allowing gear hold to be activated only in lower gears, fully utilizing engine braking during downshifts. On urban roads, the brake gear hold function is activated at a higher speed threshold, allowing gear hold to be activated in higher gears, reducing the number of gear shifts and improving driving smoothness.

[0153] Figure 3 is a schematic diagram of a road condition scene recognition and shift decision correction calculation device according to an embodiment of the present invention. Figure 3As shown, the device may include a sensor and CAN communication module 301, a road working condition scene recognition module 302, a non-road mode basic upshift point module 303, a non-road mode pre-downshift basic shift point module 304, a non-road mode post-downshift basic shift point module 305, an economy mode basic upshift point module 306, an economy mode pre-downshift basic shift point module 307, an economy mode post-downshift basic shift point module 308, a neutral coasting function module 309, a brake gear holding function module 310, and a sensor and CAN communication module 311.

[0154] Alternatively, as Figure 3 As shown, sensor and CAN communication modules 301 and 311 are responsible for collecting real-time data from various vehicle sensors, such as vehicle speed, slope estimation, turning radius, vertical ground acceleration, driving resistance, and braking signals. These data are then transmitted to other modules via the CAN bus for further processing. Furthermore, they act as a bridge between input and output, ensuring real-time communication and control of data within the system.

[0155] Alternatively, as Figure 3 As shown, the road condition scene recognition module 302 receives data from sensors and the CAN communication module 301. Based on a preset recognition algorithm, it analyzes the vehicle's current driving environment, determining whether the vehicle is operating on a highway, mountainous roads, urban roads, off-road conditions, or a national highway, and outputs a corresponding driving condition status signal. This module's driving condition recognition allows it to understand the vehicle's specific road conditions and, in turn, determine the appropriate shift strategy. This module is a key link between data collection and shift strategy adjustment, determining the level of intelligent shift decision-making. When the off-road mode basic upshift point module 303 detects that the vehicle is in an off-road condition, it adjusts the upshift point based on the specific off-road mode, ensuring more consistent power output and better traction in complex terrain. In off-road environments, vehicles require high torque in low gears to overcome challenging terrain. This module's adjustment strategy ensures vehicle stability and dynamics during off-road driving.

[0156] Alternatively, as Figure 3As shown, after identifying off-road conditions, the pre-downshift basic shift point module 304 in off-road mode adjusts the pre-downshift shift point to accommodate the power requirements and driving safety in off-road environments. This ensures that the vehicle can quickly downshift when additional power is needed, utilizing engine braking or providing greater torque to cope with complex off-road conditions. The post-downshift basic shift point module 305 in off-road mode further refines the post-downshift shift point adjustments in off-road mode to ensure optimized power output and shift timing after downshifting. By precisely controlling the post-downshift shift point, the vehicle maintains power continuity in off-road environments, avoids power interruptions during the shift process, and enhances the driving experience and safety.

[0157] Alternatively, as Figure 3 As shown, in economy mode, the basic upshift point module 306 adjusts upshift points based on road condition signals to achieve optimal fuel economy, typically reducing the speed after upshifts under highway conditions. Upshift strategy adjustments in economy mode are designed to reduce fuel consumption and improve fuel efficiency. Optimizing upshift points can reduce engine load and energy consumption, particularly under highway conditions. The basic pre-downshift shift point module 307 in economy mode adjusts the basic pre-downshift shift points based on road condition signals to achieve a smoother and more economical ride. In economy mode, precise pre-downshift shift point adjustments help reduce shift frequency and shock, improving driving comfort and overall vehicle efficiency. The basic post-downshift shift point module 308 in economy mode optimizes the post-downshift shift points in economy mode, ensuring a smooth transition to the next gear while maintaining optimal fuel efficiency under various driving conditions. Adjustments made by this module ensure more coordinated engine and transmission operation after downshifts, reducing energy waste and improving fuel efficiency.

[0158] Alternatively, as Figure 3 As shown, the neutral coasting function module 309 adjusts the activation conditions for the neutral coasting function, such as the confirmation time and the deactivation range, based on the road condition status signal. Neutral coasting can effectively save fuel in some road conditions (such as highways), but may not be applicable in other road conditions (such as mountainous areas and urban roads) and may even pose a safety hazard. Adjusting the neutral coasting function based on the road condition signal ensures that it is used at the appropriate time, improving economy without sacrificing safety. The brake gear hold function module 310 adjusts the triggering conditions for brake gear hold, such as the vehicle speed threshold and gear selection, based on the road condition status signal to adapt to driving needs under different road conditions. In mountainous road conditions, brake gear hold can be activated at lower vehicle speeds and gears to fully utilize engine braking. In urban road conditions, the function can be activated at higher vehicle speeds and gears to reduce the number of gear shifts and improve driving comfort and safety.
