Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and in particular to a gear shifting system, a control method for the gear shifting system, and a vehicle. Background Technology

[0002] The shifting system in related technologies typically includes a shift lever, such as a straight-line shift lever, a paddle shift lever, and a rotary shift lever. The driver can change the vehicle's driving gear by operating the shift lever. However, the height position of the shift lever in the shifting system of related technologies is fixed. A fixed shift lever not only affects the interior space of the vehicle, but also makes the appearance of the vehicle interior less aesthetically pleasing, resulting in a poor user experience.

Therefore, they should not be construed as limitations on this invention.

[0049] In the description of this invention, "first feature" and "second feature" may include one or more of the features.

[0050] In the description of this invention, "a plurality of" means two or more, and "several" means one or more.

[0051] The shifting system 1 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0052] like Figures 1-4 As shown, the shifting system 1 according to an embodiment of the present invention includes a shift lever 100, a shifting control mechanism 200, and a controller 300.

[0053] The shift control mechanism 200 is connected to the shift lever 100 and is used to drive the shift lever 100 to rise or fall. The controller 300 is connected to the shift control mechanism 200. When the controller receives a vehicle power-on command, it controls the shift control mechanism 200 to operate in response to the vehicle power-on command, so as to drive the shift lever 100 to rise. When the controller receives a vehicle power-off command, it controls the shift control mechanism 200 to operate in response to the vehicle power-off command, so as to drive the shift lever 100 to fall.

[0054] According to the shifting system 1 of the present invention, by connecting the shifting control mechanism 200 to the shift lever 100, the shift lever 100 is driven to rise or fall. That is, the shifting control mechanism 200 can adjust the height of the shift lever 100, and the shift lever 100 can move as a moving part. In this way, the user can adjust the shift lever 100 to a suitable height through the shifting control mechanism 200 to meet the operating habits of different users, so that the driver can change the driving gear of the vehicle by operating the shift lever 100. The driver's operating comfort is higher and the user experience is better.

[0055] Furthermore, the function of driving the shift lever 100 up or down through the shift control mechanism 200 is more stylish and technologically advanced, which helps to improve the perceived quality of the vehicle and further enhances the user's driving experience.

[0056] In addition, the controller 300 is connected to the shift control mechanism 200. When the controller 300 receives a vehicle power-on command, it responds to the vehicle power-on command and controls the shift control mechanism 200 to drive the shift lever 100 to rise. In this way, when the vehicle starts, the shift lever 100 can be raised so that the driver can normally touch and operate the shift lever 100, ensuring that the driver can change the vehicle's driving gear through the shift lever 100, making operation more convenient.

[0057] Furthermore, when the controller 300 receives a power-off command from the vehicle, it responds by controlling the shift control mechanism 200 to drive the shift lever 100 down. In other words, when the vehicle is turned off, the controller 300 will control the shift control mechanism 200 to drive the shift lever 100 down. In this way, after the vehicle is powered off, the height of the shift lever 100 can be lowered to a lower position, thereby increasing the interior storage space of the vehicle and facilitating storage. Moreover, the lower height of the shift lever 100 means that it will not be particularly prominent in the user's visual perception, making the interior of the vehicle more aesthetically pleasing.

[0058] Thus, the shifting system 1 according to the embodiment of the present invention can adjust the height of the shift lever 100, which is beneficial to increasing the storage space of the vehicle and making the vehicle interior more aesthetically pleasing.

[0059] In some specific embodiments of the present invention, such as Figure 1 As shown, when the controller 300 controls the shift control mechanism 200 to operate and drive the shift lever 100 to rise, it is specifically used to: determine whether the memory position information of the shift lever 100 is stored in the storage unit;

[0060] If so, the shift control mechanism 200 is controlled to operate, thereby driving the shift lever 100 to rise to the position corresponding to the memorized position information;

[0061] Otherwise, the shift control mechanism 200 is operated to drive the shift lever 100 to rise to the first preset position.

[0062] It should be noted that the memory position information can be the height position information of the shift lever 100 that the user has pre-stored in the storage unit. For example, the memory position information can be the position information of the shift lever 100 stored in the storage unit before the vehicle is powered off, that is, the height information of the shift lever 100 when the user drove the vehicle last time. By setting the memory position information, a height position information suitable for the driver to operate can be set for the shift lever 100, and it is convenient for the user to customize the height of the shift lever 100.

[0063] In this way, when the vehicle is powered on again, if the storage unit stores the memory position information of the shift lever 100, the shift control mechanism 200 can directly drive the shift lever 100 to rise to the position corresponding to the memory position information, without the driver having to adjust the height of the shift lever 100 again. The height raising of the shift lever 100 is more intelligent and more convenient for users.

[0064] In addition, if the storage unit does not store the memory position information of the shift lever 100, the shift control mechanism 200 drives the shift lever 100 to rise to the first preset position. In this way, even if the user does not store the memory position information of the shift lever 100 through the storage unit, the shift lever 100 can still rise normally after the vehicle is powered on, so as to ensure that the user can operate the shift lever 100 to change the driving gear of the vehicle and drive the vehicle normally.

[0065] The first preset position can be a default height setting when the vehicle leaves the factory. In this way, by raising the gear shift lever 100 to the first preset position, it can meet the operating habits of most users, or in other words, allow the vast majority of users, or even all users, to operate the gear shift lever 100 normally, so that users can drive the vehicle normally.

[0066] Furthermore, the first preset position is configured as the highest position that the shift lever 100 can be raised to. In this way, before the user sets the memory position information, the user can know the highest position that the shift lever 100 can be raised by raising the shift lever 100 to the first preset position. This allows the user to obtain the information of the highest position of the shift lever 100 more intuitively, making it easier for the user to determine whether the height of the shift lever 100 needs to be adjusted. Moreover, if the memory position information of the shift lever 100 is not stored in the storage unit, the shift control mechanism 200 can drive the shift lever 100 to rise to the highest position that can be raised, so that most users can normally touch and operate the shift lever 100 to drive the vehicle normally.

[0067] In some specific embodiments of the present invention, such as Figure 1 and Figure 2 As shown, when the controller 300 controls the operation of the shift control mechanism 200 to drive the shift lever 100 down, it is specifically used to: control the operation of the shift control mechanism 200 to drive the shift lever 100 down to the second preset position.

[0068] The second preset position can be another default height information set when the vehicle leaves the factory. In this way, when the vehicle is powered off, the controller 300 can control the shift control mechanism 200 to drive the shift lever 100 to a lower second preset position, thereby reducing the space occupied by the shift lever 100 in the passenger compartment of the vehicle, so that the storage space in the passenger compartment can be larger, which is convenient for storage and helps to improve the aesthetics of the vehicle's interior.

[0069] Furthermore, the second preset position is configured as the lowest position where the shift lever 100 can be lowered. In this way, when the vehicle is powered off, the shift control mechanism 200 can drive the shift lever 100 to lower to the lowest position, thereby minimizing the space occupied by the shift lever 100 in the passenger compartment of the vehicle. After the vehicle is powered off, the storage space in the passenger compartment can be larger and storage can be more convenient.

[0070] In this embodiment of the invention, the first preset position, the second preset position, the memory position information, and the gear position signal of the gear shift lever 100 can all be CAN (Controller Area Network) signals or CANFD (CAN with Flexible Data-Rate) signals.

[0071] In some specific embodiments of the present invention, when the shift lever 100 is lowered to the second preset position, the upper part of the shift lever 100 is located below the target component of the vehicle.

[0072] Therefore, when the vehicle is powered off, the upper part of the gear shift lever 100, that is, the highest point of the gear shift lever 100, will be located below the target component. This prevents the highest point of the gear shift lever 100 from extending upwards beyond the target component, thus allowing for more space above the target component for storage. Furthermore, with the gear shift lever 100 lowered below the target component, the interior layout of the vehicle becomes more simple and aesthetically pleasing.

[0073] Furthermore, the target components of the vehicle include the vehicle's secondary instrument panel. It should be noted that the secondary instrument panel refers to the part of the vehicle's interior located between the driver's and passenger's seats. In other words, the gear shift lever 100 can be lowered below the secondary instrument panel. This allows for more space above the secondary instrument panel when the vehicle is powered off, which can be used to store frequently used items. Furthermore, when the gear shift lever 100 is lowered below the secondary instrument panel, the secondary instrument panel can also act as a shield for the gear shift lever 100, making the layout of the secondary instrument panel appear simpler and more aesthetically pleasing, thus enhancing the appearance of the vehicle's interior and improving the user experience.

[0074] In some specific embodiments of the present invention, such as Figure 1 and Figure 4 As shown, the shift control mechanism 200 is also used to: acquire the current gear position signal of the shift lever 100 and send the gear position signal to the controller 300. The controller 300 is also used to: control the vehicle to respond to the gear position signal.

[0075] In this way, when the driver changes the gear position of the gear shift lever 100, the gear shift control mechanism 200 can obtain the current gear position signal of the gear shift lever 100 and send it to the controller 300. The vehicle can respond to the current gear position signal through the controller 300 and drive the vehicle according to the current gear position signal.

[0076] In some specific embodiments of the present invention, such as Figure 1 As shown, before controlling the vehicle to execute the gear signal, the controller 300 is also used to: determine whether the gear corresponding to the gear signal is P gear;

[0077] If so, the shift lever 100 is controlled based on whether a shift lever position setting signal is received;

[0078] Otherwise, control the vehicle to respond to the gear signal.

[0079] When the controller 300 receives the gear lever position setting signal, it means that the user needs to adjust the position of the gear lever, that is, the shift control mechanism 200 needs to drive the shift lever 100 to rise or fall.

[0080] Furthermore, the controller 300 only controls the shift lever 100 based on whether it receives a shift lever position setting signal after determining that the gear position signal is P. In other words, controlling the shift lever 100 based on the shift lever position setting signal is based on the gear position signal being P. Thus, the shift control mechanism 200 can only drive the shift lever 100 to rise or fall when the gear position signal is P and the vehicle is stationary. This avoids the driver having to adjust the height of the shift lever 100 while the vehicle is in motion, which helps improve driving safety.

[0081] Of course, if the gear signal is not P, the controller 300 can directly respond to the gear signal and control the vehicle to drive normally in the corresponding gear.

[0082] In some specific embodiments of the present invention, such as Figure 1 As shown, when the controller 300 controls the shift lever 100 based on whether it receives a shift lever position setting signal, it specifically controls the vehicle not to respond to the gear signal and keeps the gear in P gear when it determines that a shift lever position setting signal has been received.

[0083] In this way, if the controller 300 receives the gear lever position setting signal, the shift control mechanism 200 drives the shift lever 100 to rise or fall. At this time, regardless of whether the controller 300 receives the gear signal or whether the gear signal changes, the controller 300 will keep the gear in P gear, that is, keep the vehicle in a stationary state. This prevents the vehicle from starting to move when the user adjusts the gear lever height, further improving the driving safety of the vehicle, reducing the probability of accidents, and making operation safer.

[0084] In some specific embodiments of the present invention, the shifting system 1 further includes a shift lever position setting button, which, when triggered, sends a shift lever position setting signal to the controller 300.

[0085] Therefore, when the driver needs to adjust the height of the shift lever 100, he can send a shift lever position setting signal to the controller 300 by pressing the shift lever position setting button. After the controller 300 receives the driver's intention to adjust the shift lever 100, it will control the shift control mechanism 200 to drive the shift lever 100 to rise or fall, so that the shift lever 100 can be adjusted to a suitable height for the driver to operate and for a better driving experience.

[0086] Furthermore, by setting a button for the gear shift lever position, users can easily adjust the height of the gear shift lever 100 simply by pressing the button, making the operation simpler, more convenient, and easier to use.

[0087] Furthermore, the gear lever position setting button is located on the gear shift lever 100. This integration makes the button easily visible and convenient for users to press. Moreover, the function of the gear lever position setting button is to adjust the height of the gear shift lever 100. In other words, the function of the button and the gear shift lever 100 are interconnected. When users need to adjust the height of the gear shift lever 100, they will more easily locate the button from its surroundings. This design makes it easier for users to find the button and further simplifies the operation.

[0088] For example, the gear lever position setting button can be located near the upper part of the gear shift lever 100. This way, regardless of the height of the memory position information of the gear shift lever 100, even if the lower part of the gear shift lever 100 is blocked due to a decrease in the height of the gear shift lever 100, the gear lever position setting button will not be easily blocked, making it easier for the user to press the gear lever position setting button and making the operation more convenient.

[0089] In some specific embodiments of the present invention, such as Figure 1 As shown, after the controller 300 controls the gear to remain in P gear, the shift control mechanism 200 is also used to obtain the current position of the shift lever 100 and output the corresponding current position information of the lever. The controller 300 is also used to determine whether to store the current position information of the lever based on whether the lever position memory signal is received.

[0090] In this way, when the gear is kept in P gear and the height of the shift lever 100 is adjusted, the shift control mechanism 200 can continuously update the corresponding current position information of the shift lever. Thus, after receiving the shift lever position memory signal, it can stop adjusting the height of the shift lever 100 and store the current position information of the shift lever, making the storage of the current position information of the shift lever 100 more accurate.

[0091] In some specific embodiments of the present invention, such as Figure 1 As shown, when the controller 300 determines whether to store the current position information of the gear lever based on whether it receives the gear lever position memory signal, it specifically performs the following: when the gear lever position memory signal is received, it stores the current position information of the gear lever as memory position information in the storage unit and controls the vehicle to respond to the gear signal.

[0092] In other words, when the shift control mechanism 200 drives the shift lever 100 to rise or fall, the shift control mechanism 200 continuously updates the output of the current position information of the shift lever 100 corresponding to its current position. When the shift lever position memory signal is received, the controller 300 stores the current position information of the shift lever as memory position information in the storage unit. At this time, it means that the user has completed the height adjustment of the shift lever 100, and the user can drive the vehicle normally. Then, the user can control the vehicle to respond to the gear signal so that the vehicle can drive normally. With this setting, the user's adjustment of the height position of the shift lever 100 and the user's control of the vehicle will not be carried out at the same time, which is conducive to improving driving safety. Moreover, after the user has adjusted the height position of the shift lever 100, the vehicle can immediately respond to the gear signal without delaying the user's control of the vehicle, resulting in a better user experience.

[0093] In some specific embodiments of the present invention, such as Figure 1 As shown, when the controller 300 determines whether to store the current position information of the gear lever based on whether it has received the gear lever position memory signal, it specifically performs the following: when the gear lever position memory signal is not received, it controls the vehicle not to respond to the gear signal, controls the gear to remain in P gear, and receives the new gear lever position information re-output by the shift control mechanism 200, and re-determines whether to store the new gear lever position information based on whether the gear lever position memory signal has been received. The new gear lever position information is output by the shift control mechanism 200 after re-acquiring the position of the shift lever 100.

[0094] In other words, the shift control mechanism 200 can obtain the current position information of the shift lever in real time, and continuously update the current position information of the shift lever before receiving the shift lever position memory signal, keeping the gear in P gear at all times. When the controller 300 receives the shift lever position memory signal, the controller 300 controls the storage unit to store the current position information of the shift lever as memory position information. With this setting, as long as the controller 300 does not receive the position memory signal, it means that the user has not yet completed the action of adjusting the height of the shift lever 100, and the gear is kept in P gear. This prevents the vehicle from starting to move while the user is adjusting the height of the shift lever 100, further improving the safety of the user during the process of adjusting the height of the shift lever 100.

[0095] In some specific embodiments of the present invention, the shifting system 1 further includes a shift lever position memory button, which sends a shift lever position memory signal to the controller 300 when the shift lever position memory button is triggered.

[0096] Therefore, when the driver needs to store the current position information of the gear lever in the storage unit, he can send a gear lever position memory signal to the controller 300 by pressing the gear lever position memory button. After the controller 300 obtains the driver's intention to store the current position information of the gear lever, the controller 300 will control the storage unit to store the current position information of the gear lever, so that when driving the vehicle next time, the gear lever 100 can be directly raised to the position corresponding to the memory position information of the gear lever 100, which is convenient for the driver to operate and provides a better driving experience.

[0097] Furthermore, by setting a shift lever position memory button, users can simply press the button to store the current position information of the shift lever into the storage unit when they need to do so, making the operation simpler and more convenient.

[0098] Furthermore, the gear lever position memory button is located on the gear shift lever 100.

[0099] Integrating the gear lever position memory button onto the gear shift lever 100 makes it easy for users to observe and press. Furthermore, the function of the gear lever position memory button is interconnected with the gear shift lever 100. When users need to store the height position of the gear shift lever 100 as memory position information in the storage unit, they will more easily recall finding the gear lever position memory button around the gear shift lever 100. This design makes it easier for users to find the gear lever position memory button and further simplifies user operation.

[0100] For example, the gear lever position memory button can also be set near the upper part of the gear shift lever 100. In this way, no matter what the height of the memory position information of the gear shift lever 100 is, even if the height of the gear shift lever 100 decreases and the lower part of the gear shift lever 100 is blocked, the gear lever position memory button will not be easily blocked, so that the user can press the gear lever position memory button and the operation is more convenient.

[0101] In some specific embodiments of the present invention, such as Figure 1 As shown, when the controller 300 controls the shift lever 100 based on whether it receives a shift lever position setting signal, it specifically performs the following: when it is determined that no shift lever position setting signal has been received, it determines whether a shift lever position reset signal has been received;

[0102] If so, the vehicle is controlled to respond to the gear signal, and the shift control mechanism 200 is controlled to operate, so as to drive the shift lever 100 to rise to the first preset position;

[0103] Otherwise, control the vehicle to respond to the gear signal.

[0104] Thus, when the controller 300 does not receive the gear lever position setting signal but receives the gear lever position reset signal, regardless of whether the gear lever 100 was previously in the position corresponding to the memory position information or in the first preset position, the controller 300 will control the gear shift control mechanism 200 to drive the gear lever 100 to rise to the first preset position so that the user can operate the gear lever 100. At the same time, the controller 300 will control the vehicle to respond to the gear signal to drive the vehicle.

[0105] When the controller 300 does not receive the gear lever position setting signal and does not receive the gear lever position reset signal, the controller 300 directly controls the vehicle to respond to the gear signal so that the driver can control the vehicle to drive.

[0106] In some specific embodiments of the present invention, the shifting system 1 further includes a shift lever position reset button, which, when triggered, sends a shift lever position reset signal to the controller 300.

[0107] Therefore, when the driver needs to reset the position of the shift lever 100, he can send a shift lever position reset signal to the controller 300 by pressing the shift lever position reset button. After the controller 300 obtains the driver's intention to reset the position of the shift lever 100, the controller 300 will control the shift control mechanism 200 to drive the shift lever 100 to rise to the first preset position.

[0108] Furthermore, by setting a shift lever position reset button, when users need to reset the position of the shift lever 100, they only need to press the button to reset the shift lever 100 to the first preset position, making the operation simpler and more convenient.

[0109] Furthermore, a shift lever position reset button is located on the shift lever 100.

[0110] In this way, integrating the gear lever position reset button onto the gear shift lever 100 makes it easy for users to see and press. Moreover, the function of the gear lever position reset button is interrelated with that of the gear shift lever 100. When users need to reset the height of the gear shift lever 100 to the first preset position, they will more easily think of finding the gear lever position reset button around the gear shift lever 100. This design makes it easier for users to find the gear lever position reset button and further simplifies the user's operation.

[0111] For example, the gear lever position reset button can also be located near the upper part of the gear shift lever 100. In this way, no matter what the height of the memory position information of the gear shift lever 100 is, even if the height of the gear shift lever 100 decreases and the lower part of the gear shift lever 100 is blocked, the gear lever position reset button will not be easily blocked, so that the user can press the gear lever position reset button and the operation is more convenient.

[0112] In some specific embodiments of the present invention, such as Figure 1 As shown, after receiving the vehicle power-on command, the controller 300 is also used to: determine whether a driving authorization signal has been received;

[0113] If so, respond to the vehicle power-on command to control the operation of the shift control mechanism 200 to drive the shift lever 100 to rise;

[0114] Otherwise, it will not respond to the vehicle power-on command and will not control the operation of the shift control mechanism 200.

[0115] For example, when the vehicle key signal is detected, or an authorization instruction to use the vehicle is received from the user via the terminal, or an authorization instruction to use the vehicle is received from the cloud server, or an authorized user is identified in the vehicle through image recognition or voice recognition, it is considered that a driving authorization signal has been received.

[0116] In this way, only authorized users of the vehicle can normally change the vehicle's driving gear by operating the gear shift lever 100, thereby controlling the vehicle's movement. Unauthorized users cannot change the vehicle's driving gear by operating the gear shift lever 100, and therefore cannot normally control the vehicle's movement. This helps improve the vehicle's anti-theft performance and greatly reduces the possibility of accidental operation. For example, it prevents children from accidentally operating the gear shift lever 100 inside the car and driving the vehicle, further improving the vehicle's driving safety.

[0117] In some specific embodiments of the present invention, such as Figure 4As shown, the shift control mechanism 200 includes a gear position sensing unit 210, a drive unit 220, a power supply unit 230, and a main control unit 240. The main control unit 240 can be an MCU (Microcontroller Unit) or an FPGA (Field Programmable Gate Array).

[0118] The gear position sensing unit 210 is connected to the gear shift lever 100 and is used to acquire the gear position signal of the gear shift lever 100. The drive unit 220 is connected to the gear shift lever 100 and is used to drive the gear shift lever 100 to rise or fall. The power supply unit 230 is used to supply power to the gear position sensing unit 210 and the drive unit 220. The main control unit 240 is used to control the operation of the power supply unit 230.

[0119] In this way, the shift control mechanism 200 can form a complete system. After the vehicle is powered on, the main control unit 240 can control the power supply unit 230 to ensure the normal operation of the gear position sensing unit 210 and the drive unit 220. The gear position sensing unit 210 can obtain the gear position signal of the shift lever 100 and transmit it to the controller 300, so that the controller 300 can drive the vehicle according to the gear position signal of the shift lever 100. In addition, the controller 300 can also control the drive unit 220 to drive the shift lever 100 to rise or fall, so as to adjust the height position of the shift lever 100 for easy operation by the user.

[0120] In some specific embodiments of the present invention, such as Figure 3 As shown, the gear position sensing unit 210 includes a Hall sensor or a first servo module 211.

[0121] The first servo module 211 is used to identify the movement angle of the gear shift lever 100, convert the movement angle into angular torque, and generate a gear position signal based on the angular torque. In this embodiment of the invention, the gear position signal can be calculated using a PID (Proportional, Integral, Differential) algorithm.

[0122] In other words, the gear position sensing unit 210 can directly sense the gear position signal of the gear shift lever 100 through the Hall sensor and transmit the detected gear position signal of the gear shift lever 100 to the controller 300.

[0123] Alternatively, the gear position sensing unit 210 can also identify the movement angle of the gear shift lever 100 through the first servo module 211. For example, the first servo module 211 can be constructed as a first gear, and the lower part of the gear shift lever 100 can be constructed with a second gear 110 that meshes with the first gear. When the driver changes the gear position of the gear shift lever 100, the gear shift lever 100 rotates, and the gear shift lever 100 drives the second gear 110 to rotate. The second gear 110 then drives the first gear to rotate. Thus, the rotation angle of the second gear 110 can be determined based on the rotation angle of the first gear. That is, the movement angle of the gear shift lever 100 is obtained through the movement angle of the first servo module 211, and the movement angle is converted into angular torque. The gear position signal generated based on the angular torque is then transmitted to the controller 300, and the controller 300 controls the vehicle to drive according to the gear position signal.

[0124] In some specific embodiments of the present invention, such as Figure 3 As shown, the drive unit 220 includes a second servo module 221.

[0125] The second servo module 221 is used to output a first vertical torque to the shift lever 100 to drive the shift lever 100 to rise or fall. In this way, the drive unit 220 can adjust the height of the shift lever 100 through the second servo module 221 so that the shift lever 100 can be raised or lowered to a suitable height for driver control.

[0126] Furthermore, the second servo module 221 is also used to acquire the second vertical torque generated when the shift lever 100 rises or falls, and calculate the position information of the shift lever 100 based on the second vertical torque. In this way, the second servo module 221 can convert the second vertical torque into the corresponding memory position information of the shift lever 100, and control the power supply unit 230 to provide a stable voltage to the drive unit 220, so that the drive unit 220 can stably drive the shift lever 100 to the position corresponding to the memory position information.

[0127] For example, such as Figure 3As shown, the second servo module 221 can be configured as a third gear, and the side of the second servo module 221 facing the third gear has a tooth groove 222 that meshes with the third gear. The tooth groove 222 can be arranged along the length direction of the second servo module 221, that is, along the vertical direction. In this way, when the drive module drives the third gear to rotate clockwise (or counterclockwise), the third gear can drive the shift lever 100 and the second servo module 221 to rise (or fall) together. When the drive module drives the third gear to rotate counterclockwise (or clockwise), the third gear can drive the shift lever 100 and the second servo module 221 to fall (or rise) together. Thus, the shift lever 100 can be raised and lowered through the bidirectional rotation of the third gear. Furthermore, the shift control mechanism 200 can also obtain the moving distance of the shift lever 100 based on the rotation distance of the third gear, and then determine the height of the shift lever 100 after moving to obtain the position information of the shift lever 100 after moving.

[0128] Specifically, when the third gear rotates and moves to the uppermost end of the tooth groove 222 relative to the shift lever 100, the shift lever 100 descends to the lowest position that can be lowered. When the third gear rotates and moves to the lowermost end of the tooth groove 222 relative to the shift lever 100, the shift lever 100 rises to the highest position that can be raised.

[0129] In addition, in some embodiments of the present invention, a limiting rod 223 extending horizontally may be provided on one side of the second servo module 221, and a limiting groove 224 extending vertically may be provided in the shift control mechanism 200. The limiting rod 223 extends into the limiting groove 224 and slides within the limiting groove 224 when the shift lever 100 rises or falls. When the shift lever 100 rises to the highest position it can rise to, the limiting rod 223 abuts against the uppermost end of the limiting groove 224. When the shift lever 100 falls to the lowest position it can fall to, the limiting rod 223 abuts against the lowermost end of the limiting groove 224. Thus, the highest and lowest positions of the shift lever 100 can be physically limited by the cooperation of the limiting groove 224 and the limiting rod 223, which helps to improve the accuracy of the shift control mechanism 200 in limiting the height of the shift lever 100 and achieves better positioning effect.

[0130] The control method applied to a shift system 1 according to an embodiment of the present invention is described below with reference to the accompanying drawings. The control method includes the following steps:

[0131] Receives a vehicle power-on command or a vehicle power-off command;

[0132] In response to the vehicle power-on command, the shift control mechanism 200 is operated to drive the shift lever 100 to rise;

[0133] In response to the vehicle power-off command, the shift control mechanism 200 is operated to drive the shift lever 100 down.

[0134] Specifically, such as Figure 1 As shown, firstly, when the controller 300 receives the vehicle's power-on command, the controller 300 first determines whether a driving authorization signal has been received. If a driving authorization signal is received, it determines whether the memory position information of the shift lever 100 is stored in the storage unit. If no driving authorization signal is received, it does not respond to the vehicle's power-on command and does not control the shift control mechanism 200 to operate.

[0135] If the storage unit stores the memory position information of the shift lever 100, the shift lever 100 is controlled to rise to the position corresponding to the memory position information. If the storage unit does not store the memory position information of the shift lever 100, the shift lever 100 is controlled to rise to the first preset position.

[0136] Furthermore, after the shift lever 100 is raised to the position corresponding to the memory position information or to the first preset position, the shift control mechanism 200 acquires the current gear position signal of the shift lever 100 and sends the gear position signal to the controller 300. The controller 300 determines whether the current gear is P gear. If it is P gear, it determines whether it has received the shift lever position setting signal. If it is not P gear, the controller 300 controls the vehicle to respond to the current gear position signal.

[0137] If the current gear is in P (Park) and the controller 300 receives the gear lever position setting signal, it controls the vehicle not to respond to the gear signal and keeps the gear in P. It then obtains the current position of the gear lever 100, outputs the corresponding current gear lever position information, and determines whether it has received a gear lever position memory signal. If the controller 300 receives the gear lever position memory signal, it stores the current gear lever position information as memory position information in the storage unit and controls the vehicle to respond to the gear signal. If the controller 300 does not receive the gear lever position memory signal, it controls the vehicle not to respond to the gear signal and keeps the gear in P. It receives the new gear lever position information re-output by the shift control mechanism 200 and re-determines whether to store the new gear lever position information based on whether it has received the gear lever position memory signal. This process continues until the controller 300 receives the gear lever position memory signal, at which point it stores the latest current gear lever position information as memory position information in the storage unit and controls the vehicle to respond to the gear signal.

[0138] If the current gear is in P gear and the controller 300 has not received a gear lever position setting signal, it determines whether the controller 300 has received a gear lever position reset signal. If the controller 300 receives a gear lever position reset signal, it controls the vehicle to respond to the gear signal and controls the shift control mechanism 200 to drive the shift lever 100 to rise to the first preset position. If the controller 300 has not received a gear lever position reset signal, it controls the vehicle to respond to the gear signal.

[0139] When the controller 300 receives a power-off command from the vehicle, it controls the shift control mechanism 200 to operate, thereby driving the shift lever 100 to descend to the second preset position.

[0140] According to the control method applied to the gear shifting system 1 according to the embodiment of the present invention, the height of the gear shift lever 100 can be adjusted, which is beneficial to increasing the storage space of the vehicle and making the interior of the vehicle more beautiful.
