Description

Technical Field

[0001] This invention relates to the field of new energy vehicle technology, and in particular to a method, device, electronic device, and storage medium for displaying gear positions on a dual electric drive axle. Background Technology

[0002] With the development of new energy technologies, the configurations of new energy vehicle models are becoming increasingly diverse. Electric drive axle configurations have gradually emerged due to their high integration, small size, light weight, and ability to reduce overall vehicle costs. Electric drive axle configuration vehicles are divided into single-axle, dual-axle, and multi-axle configurations. For single-axle configurations, the shifting process is relatively simple, basically the same as that of electric drive transmission configurations; for dual-axle configurations, the shifting process is more complex, allowing for simultaneous shifting of both axles, continuous alternating shifting of both axles, or shifting of one axle while the other remains stationary.

[0003] Patent CN116587880A, entitled "A Cooperative Control Method for Dual-Axle Electric Drive Axles, Dual-Axle Electric Drive Axles and Vehicles", proposes that in dual-axle drive mode, the torque distribution strategy of the dual-axle electric drive axles is optimized according to the vehicle speed and the driving torque required by the driver, so as to ensure the economy of the dual-axle electric drive axle drive control and thus optimize vehicle performance.

[0004] Patent CN118514509A, entitled "A Dual-Connected Electric Drive Axle Thermal Management System, Method, Electronic Equipment and Storage Medium", proposes a dual-connected electric drive axle thermal management system. It controls the connection and disconnection between the electric drive axle thermal management system and the vehicle thermal management system through a flow control valve and a two-way valve, thereby meeting the cooling requirements of the electric drive axle and reducing the occupancy of the cooling medium flow of the vehicle thermal management system.

[0005] Patent CN220570399U, "Electric Drive Bridge Motor Protection Structure and Electric Drive Bridge", proposes an electric drive bridge motor protection structure and an electric drive bridge. The protection structure includes a housing and a cooling plate. By setting up the cooling plate and a cooling fan, the electric drive bridge motor in operation is simultaneously cooled by air and coolant, which can maintain the good working condition of the electric drive bridge motor and the electric drive bridge.

[0006] While the aforementioned patents have optimized the thermal management, torque distribution, and structural design of the electric drive axle, they have not proposed a solution for the instrument display of the dual-axle configuration of the electric drive axle.

[0007] In a dual-axle configuration, each axle has an independent gear position. Displaying the gear positions of both axles simultaneously on the instrument panel would interfere with the driver's judgment of the overall vehicle gear status. Furthermore, the instrument panel display area is limited, and displaying the gear positions of both axles would occupy additional display space. Illuminating the gear position symbols for both axles would also increase the instrument panel's power consumption. Therefore, the rational design of the gear position display for a dual-axle configuration has a significant impact on the vehicle's fuel efficiency and driving experience. Summary of the Invention

[0008] The purpose of this invention is to provide a method, device, electronic device, and storage medium for displaying dual electric drive axle gear positions, which can avoid the space occupied by displaying dual axle gear positions and reduce the power consumption of the instrument. It provides a display method that displays only one gear position, which can prevent users from interfering with driving judgment and affecting driving experience by viewing two gear positions at the same time, thereby improving the user's driving experience.

[0009] To solve the above-mentioned technical problems, in a first aspect, the present invention provides a dual-electric drive bridge gear position display method, comprising at least:

[0010] Get the gear position of the gear shift lever;

[0011] If the handle position is N, then determine whether the vehicle is in service mode;

[0021] If both the first electric drive axle and the second electric drive axle are in the starting gear position, then the current vehicle gear is displayed as N gear in the vehicle instrument panel.

[0022] Optionally, after obtaining the gear positions of the first electric drive axle and the second electric drive axle if the vehicle is not in the service mode, the method further includes:

[0023] If the gear position of either the first electric drive bridge or the second electric drive bridge is not the starting gear position, then it is determined whether the first electric drive bridge or the second electric drive bridge is faulty.

[0024] If the first electric drive axle or the second electric drive axle malfunctions, the gear position of the electric drive axle that is not malfunctioning will be displayed in the vehicle's instrument panel, and the user will be notified that the corresponding electric drive axle has malfunctioned.

[0025] If both the first electric drive axle and the second electric drive axle fail, the gear corresponding to the dual electric drive axles at the previous moment will be displayed in the vehicle's instrument panel.

[0026] Optionally, after obtaining the gear shift lever's gear position, the method further includes:

[0027] If the lever position is D / R, then determine whether there is a gear engagement fault in the first electric drive bridge and the second electric drive bridge;

[0028] If neither of them has the aforementioned gear shifting fault, then determine whether the gear positions of the first electric drive axle and the second electric drive axle are the same;

[0029] If they are the same, the gear position of either electric drive axle will be displayed in the vehicle's instrument panel;

[0030] If they are different, then continue to determine whether the shifting state of the first electric drive bridge and the second electric drive bridge meets the conditions that the first / second electric drive bridge is in the process of shifting up or down, and the other electric drive bridge has not performed shifting up or down operation;

[0031] If the condition is met, the gear position of the electric drive axle that has not performed upshifting or downshifting will be displayed in the vehicle's instrument panel.

[0032] Optionally, after determining whether the first / second electric drive axle is in the process of shifting gears if they differ, and whether the other electric drive axle has not performed a shifting operation, the method further includes:

[0033] If not satisfied, the gear position of any of the electric drive axles is displayed in the vehicle's instrument panel;

[0034] After determining whether there is a gear engagement fault in the first and second electric drive axles if the gear position is D / R, the method further includes:

[0035] If the gear shifting fault exists, determine whether both the first electric drive bridge and the second electric drive bridge are faulty;

[0036] If the first electric drive axle or the second electric drive axle malfunctions, the gear position of the electric drive axle that is not malfunctioning will be displayed in the vehicle's instrument panel, and the user will be notified that the corresponding electric drive axle has malfunctioned.

[0037] If both the first electric drive axle and the second electric drive axle fail, the vehicle's instrument panel will display the gear corresponding to the dual electric drive axles at the previous moment.

[0038] Secondly, the present invention also provides a dual-electric-drive bridge gear position display device, comprising at least:

[0039] The handle acquisition module is used to acquire the gear position of the gear shift handle;

[0040] The service determination module is used to determine whether the vehicle is in service mode when the handle gear position is in the N position;

[0041] The status display module is used to obtain the gear position of the dual electric drive axles when the vehicle is in the service mode, and display the corresponding electric drive axle status information in the vehicle instrument panel based on the gear position.

[0042] Thirdly, the present invention also provides an electronic device, including a memory and a processor, wherein the memory stores a computer program executable on the processor, and the processor executes the program to implement the steps in the dual electric drive bridge gear display method of any one of the first aspects.

[0043] Fourthly, the present invention also provides a computer-readable storage medium having a computer program stored thereon, wherein the computer program, when executed by a processor, implements the steps of the dual electric drive bridge gear display method described in any one of the first aspects.

[0044] The technical solution provided in this embodiment first obtains the gear position of the gear shift lever; second, if the gear position is in the N position, it determines whether the vehicle is in service mode; finally, if the vehicle is in service mode, it obtains the gear position of the dual electric drive axles and displays the corresponding electric drive axle status information in the vehicle instrument panel based on the gear position.

[0045] Therefore, this embodiment, based on the fact that each electric drive axle has its own gear, is set to display only one total gear. This avoids the problem of displaying both axle gears at the same time occupying instrument space and reducing instrument power consumption. It is also compatible with the display method of electric drive boxes and traditional vehicles that only display one gear. This can prevent the driver from interfering with driving judgment and affecting driving experience by looking at two gears at the same time. It helps to reduce instrument power consumption and ensure the user's driving experience. Attached Figure Description

[0058] Figure 1 This is a flowchart of a dual electric drive axle gear display method provided by an embodiment of the present invention. This embodiment is applicable to at least various display scenarios of dual electric drive axle gears in new energy vehicles. The dual electric drive axle gear display method can be, but is not limited to, executed by the dual electric drive axle gear display device in this embodiment as the execution subject, which can be implemented in software and / or hardware. Figure 1 As shown, the dual-electric drive axle gear position display method includes at least the following steps:

[0059] S1. Obtain the gear position of the gear shift lever.

[0060] The gear shift lever can be the gear control lever of a new energy vehicle. The gear position of the lever can be the resting position of the gear control lever.

[0061] S2. If the lever position is in the N position, determine whether the vehicle is in service mode.

[0062] The N position can be the neutral position. The service mode refers to a special working mode for the vehicle during maintenance, repair, or function debugging. When the service mode is activated, the working gear of the dual electric drive axle will automatically be placed in N.

[0063] S3. If the vehicle is in service mode, obtain the gear position of the dual electric drive axles and display the corresponding electric drive axle status information in the vehicle instrument panel based on the gear position.

[0064] The gear position can be the operating gear of the dual electric drive axles. In one specific implementation, optionally, the dual electric drive axles include at least a first electric drive axle and a second electric drive axle. The electric drive axle status information can include the gear position, fault information, etc. It is understood that, to ensure uninterrupted power during gear shifting, the dual electric drive axle vehicle can adopt a dual-axle alternating gear shifting strategy, that is, one electric drive axle completes the gear shift first, and the other electric drive axle will immediately shift gears after the first electric drive axle completes the gear shift.

[0065] The technical solution provided in this embodiment first obtains the gear position of the gear shift lever; second, if the gear position is in the N position, it determines whether the vehicle is in service mode; finally, if the vehicle is in service mode, it obtains the gear position of the dual electric drive axles and displays the corresponding electric drive axle status information in the vehicle instrument panel based on the gear position.

[0066] Therefore, this embodiment, based on the fact that each electric drive axle has its own gear, is set to display only one total gear. This avoids the problem of displaying both axle gears at the same time occupying instrument space and reducing instrument power consumption. It is also compatible with the display method of electric drive boxes and traditional vehicles that only display one gear. This can prevent the driver from interfering with driving judgment and affecting driving experience by looking at two gears at the same time. It helps to reduce instrument power consumption and ensure the user's driving experience.

[0067] Based on the above embodiments or implementation methods Figure 2 This is a flowchart of another dual-electric drive axle gear position display method provided in an embodiment of the present invention. Figure 3 This is a flowchart of another dual-electric drive axle gear position display method provided in this embodiment of the invention. This embodiment is based on the above embodiment and includes additional steps. Figure 2 and Figure 3 As shown, the dual-electric drive axle gear position display method includes at least the following steps:

[0068] S1. Obtain the gear position of the gear shift lever.

[0069] S41. If the lever position is in the D / R position, determine whether there is a gear engagement fault in the first electric drive bridge and the second electric drive bridge.

[0070] Here, D / R gear position can be understood as D gear position or R gear position. Gear shifting failure may be that the electric drive axle cannot upshift or downshift. In another specific implementation, optionally, step S41 specifically includes:

[0071] (41-1) If there is a gear shifting fault, determine whether both the first electric drive bridge and the second electric drive are faulty.

[0072] (41-2) If the first electric drive axle or the second electric drive axle fails, the gear position of the electric drive axle that has not failed will be displayed in the vehicle instrument panel, and the user will be notified that the corresponding electric drive axle has failed.

[0073] In this context, a failure of the first or second electric drive bridge can be understood as a failure of only one of the first and second electric drive bridges.

[0074] (41-3) If both the first and second electric drive axles fail, the vehicle instrument panel will display the gear corresponding to the two electric drive axles at the previous moment.

[0075] S42. If there is no gear shifting fault, determine whether the gear positions of the first electric drive axle and the second electric drive axle are the same.

[0076] In this context, determining whether the gear positions of the first electric drive axle and the second electric drive axle are the same can be understood as determining whether the current gear status of the first electric drive axle and the second electric drive axle is R gear, D gear, etc.

[0077] S43. If they are the same, the gear position of either electric drive axle will be displayed in the vehicle's instrument panel.

[0078] Taking an example where both the first and second electric drive axles have 4 gears: The host computer controls both the first and second electric drive axles to be in gear 1, at which point the vehicle's instrument panel displays gear 1; the host computer controls both the first and second electric drive axles to be in gear 2, at which point the vehicle's instrument panel displays gear 2; the host computer controls both the first and second electric drive axles to be in gear 3, at which point the vehicle's instrument panel displays gear 3; the host computer controls both the first and second electric drive axles to be in gear 4, at which point the vehicle's instrument panel displays gear 4.

[0079] S44. If they are different, continue to determine whether the shifting state of the first electric drive bridge and the second electric drive bridge meets the conditions that the first / second electric drive bridge is in the process of shifting up or down, and the other electric drive bridge has not performed shifting up or down.

[0080] The phrase "the first / second electric drive axle is in the process of shifting gears" and "the other electric drive axle is not performing shifting gears" can be interpreted as follows: in the first and second electric drive axles, one electric drive axle is in the process of shifting gears, while the other electric drive axle is not performing shifting gears.

[0081] In yet another specific embodiment, optionally, after step S44, the method further includes:

[0082] (44-1) If not satisfied, the gear position of any electric drive axle will be displayed in the vehicle instrument panel.

[0083] S45. If satisfied, the gear position of the electric drive axle that has not performed upshifting or downshifting operations will be displayed in the vehicle's instrument panel.

[0084] For example, the host computer controls the first electric drive axle to be in gear 1 and the second electric drive axle to be in gear 2, at which point the vehicle's instrument panel displays gear 1; the host computer controls the first electric drive axle to be in gear 2 and the second electric drive axle to be in gear 3, at which point the vehicle's instrument panel displays gear 2; the host computer controls the first electric drive axle to be in gear 3 and the second electric drive axle to be in gear 4, at which point the vehicle's instrument panel displays gear 3.

[0085] S2. If the lever position is in the N position, determine whether the vehicle is in service mode.

[0086] S51. If the vehicle is not in service mode, obtain the gear positions of the first electric drive axle and the second electric drive axle.

[0087] In one specific implementation, optionally, after step S51, the method further includes:

[0088] (51-1) If the gear position of either the first electric drive bridge or the second electric drive bridge is not the starting gear position, then determine whether the first electric drive bridge or the second electric drive bridge is faulty.

[0089] Understandably, the starting gear can be the gear that the driver returns to neutral (N) during normal driving. At this time, the working gear of the dual electric drive axle is not neutral, but the starting gear, which can be second gear.

[0090] (51-2) If the first electric drive axle or the second electric drive axle fails, the gear position of the electric drive axle that has not failed will be displayed in the vehicle instrument panel, and the user will be notified that the corresponding electric drive axle has failed.

[0091] For example, the host computer can control the first electric drive axle to be in gear 0 and the second electric drive axle to be in gear 1, at which point the instrument displays gear 1. The host computer can also control the first electric drive axle to be in gear 0 and the second electric drive axle to be in gear 2, at which point the instrument displays gear 2. The host computer can also control the first electric drive axle to be in gear 0 and the second electric drive axle to be in gear 3, at which point the instrument displays gear 3. The host computer can also control the first electric drive axle to be in gear 0 and the second electric drive axle to be in gear 4, at which point the instrument displays gear 4.

[0092] (51-3) If both the first and second electric drive axles fail, the gear corresponding to the two electric drive axles at the previous moment will be displayed in the vehicle instrument panel.

[0093] S52. If both the first electric drive axle and the second electric drive axle are in the starting gear position, the current vehicle gear will be displayed as N gear in the vehicle instrument panel.

[0094] S31. If the vehicle is in service mode, obtain the gear positions of the first electric drive axle and the second electric drive axle.

[0095] S32. If either the first electric drive axle or the second electric drive axle is not in the neutral (N) position, the vehicle instrument panel will display that the vehicle has not entered service mode and the corresponding fault information.

[0096] S33. If both the first electric drive axle and the second electric drive axle are in the N position, the vehicle instrument panel will display that the current vehicle gear is N and prompt the user that the vehicle has entered service mode.

[0097] The technical solution provided in this embodiment first obtains the gear position of the gear shift lever. Further, if the gear shift lever position is in the D / R position, it is determined whether there is a gear engagement fault in the first and second electric drive axles. Further, if there is no gear engagement fault, it is determined whether the gear positions of the first and second electric drive axles are the same. Further, if they are the same, the gear position of either electric drive axle is displayed in the vehicle's instrument panel. Further, if they are different, it is further determined whether the shifting state of the first and second electric drive axles satisfies the condition that the first / second electric drive axle is in the process of upshifting or downshifting, and that the other electric drive axle has not performed upshifting or downshifting operations. Further, if this condition is met, the gear position of the electric drive axle that has not performed upshifting or downshifting operations is displayed in the vehicle's instrument panel. Further, if the gear shift lever position is in the N position, it is determined whether the vehicle is in service mode. Further, if the vehicle is not in service mode, the gear positions of the first and second electric drive axles are obtained. Furthermore, if both the first and second electric drive axles are in the starting gear position, the vehicle's instrument panel will display that the current gear is N (Neutral). Further, if the vehicle is in service mode, the gear positions of the first and second electric drive axles will be retrieved. Further, if neither the first nor the second electric drive axle is in N gear, the vehicle's instrument panel will display that the vehicle has not entered service mode and the corresponding fault information. Finally, if both the first and second electric drive axles are in N gear, the vehicle's instrument panel will display that the current gear is N and the user will be prompted that the vehicle has entered service mode.

[0098] Therefore, this embodiment, based on the fact that each electric drive axle has its own gear, is set to display only one total gear. This avoids the problem of displaying both axle gears at the same time occupying instrument space and reducing instrument power consumption. It is also compatible with the display method of electric drive boxes and traditional vehicles that only display one gear. This can prevent the driver from interfering with driving judgment and affecting driving experience by looking at two gears at the same time. It helps to reduce instrument power consumption and ensure the user's driving experience.

[0099] Figure 4 This is a schematic diagram of a dual electric drive axle gear position display device provided in an embodiment of the present invention. This embodiment is applicable to at least various new energy vehicle dual electric drive axle gear position display scenarios. The dual electric drive axle gear position display device can be implemented using software and / or hardware. For example... Figure 4As shown, the dual-electric drive bridge gear position display device includes at least:

[0100] The handle acquisition module 110 is used to acquire the gear position of the shift handle.

[0101] The service judgment module 120 is used to determine whether the vehicle is in service mode when the lever position is in the N position.

[0102] The status display module 130 is used to obtain the gear position of the dual electric drive axles when the vehicle is in service mode, and display the corresponding electric drive axle status information in the vehicle instrument panel based on the gear position.

[0103] Optionally, the dual electric drive bridge includes at least a first electric drive bridge and a second electric drive bridge;

[0104] The status display module 130 is specifically used for:

[0105] When the vehicle is in service mode, the gear position of the first electric drive axle and the second electric drive axle is obtained; and when both the first electric drive axle and the second electric drive axle are in the N position, the current vehicle gear is displayed in the vehicle instrument panel and the user is prompted that the vehicle has entered service mode.

[0106] Optionally, the status display module 130 is also specifically used for:

[0107] When the vehicle is not in service mode, obtain the gear position of the first electric drive axle and the second electric drive axle; and when both the gear positions of the first electric drive axle and the second electric drive axle are in the starting gear position, display the current vehicle gear as N gear in the vehicle instrument panel.

[0108] Optionally, the status display module 130 is also specifically used for:

[0109] When either the first electric drive axle or the second electric drive axle is not in the starting gear position, determine whether the first electric drive axle or the second electric drive axle is faulty; and when the first electric drive axle or the second electric drive axle is faulty, display the gear position of the electric drive axle that is not faulty in the vehicle instrument panel and prompt the user that the corresponding electric drive axle is faulty; and when both the first electric drive axle and the second electric drive axle are faulty, display the gear position of the two electric drive axles at the previous moment in the vehicle instrument panel.

[0110] Optionally, it also includes:

[0111] The fault display module 140 is used to determine whether there is a gear engagement fault in the first electric drive axle and the second electric drive axle when the lever gear position is in the D / R position; and, when there is no gear engagement fault, to determine whether the gear positions of the first electric drive axle and the second electric drive axle are the same; and, when the gear positions of the first electric drive axle and the second electric drive axle are the same, to display the gear position of either electric drive axle in the vehicle instrument panel; and, when the gear positions of the first electric drive axle and the second electric drive axle are different, to continue to determine whether the shifting state of the first electric drive axle and the second electric drive axle meets the condition that the first / second electric drive axle is in the process of shifting up or down, and the other electric drive axle has not performed a shifting up or down operation; and, when the shifting state of the first electric drive axle and the second electric drive axle meets the condition that the first / second electric drive axle is in the process of shifting up or down, and the other electric drive axle has not performed a shifting up or down operation, to display the gear position of the electric drive axle that has not performed a shifting up or down operation in the vehicle instrument panel.

[0112] Optionally, the fault display module 140 is also used for:

[0113] When the shifting state of the first and second electric drive axles does not meet the requirements of the first / second electric drive axle being in a shifting or upshifting process, or when the other electric drive axle is not performing a shifting or upshifting operation, the vehicle instrument panel displays the gear position of either electric drive axle; when there is a shifting fault in the first and second electric drive axles, the system continues to check whether both the first and second electric drive axles have faults; when a fault occurs in the first or second electric drive axle, the vehicle instrument panel displays the gear position of the electric drive axle that is not faulty and prompts the user that the corresponding electric drive axle has a fault; and when both the first and second electric drive axles have faults, the vehicle instrument panel displays the gear position corresponding to both electric drive axles at the previous moment.

[0114] The technical solution provided in this embodiment firstly acquires the gear position of the gear shift lever through a lever acquisition module. Secondly, when the gear shift lever is in the neutral (N) position, a service determination module determines whether the vehicle is in service mode. Finally, when the vehicle is in service mode, a status display module acquires the gear positions of the dual electric drive axles and displays the corresponding electric drive axle status information in the vehicle's instrument panel based on the gear positions.

[0115] Therefore, this embodiment, based on the fact that each electric drive axle has its own gear, is set to display only one total gear. This avoids the problem of displaying both axle gears at the same time occupying instrument space and reducing instrument power consumption. It is also compatible with the display method of electric drive boxes and traditional vehicles that only display one gear. This can prevent the driver from interfering with driving judgment and affecting driving experience by looking at two gears at the same time. It helps to reduce instrument power consumption and ensure the user's driving experience.
