[0002] Before starting a vehicle, it is usually necessary to engage a gear. The higher the gear position on the mechanical lever, the easier it is to achieve a higher vehicle speed. Therefore, some drivers habitually engage third or fourth gear when starting the vehicle. However, higher gears also put greater pressure on the clutch plates within the transmission, thus accelerating clutch wear. With the further development of vehicle control technology, there is an urgent need for a gear control method that can extend the lifespan of the vehicle's clutch. Summary of the Invention

[0022] The vehicle control signal is transmitted to the engine electronic control unit, which instructs the engine electronic control unit to control the engine to generate operating power that matches the preset gear.

[0023] In one embodiment, the preset gear is the first gear.

[0024] Secondly, this application also provides a gear control device, comprising:

[0025] The speed acquisition module is used to obtain the current vehicle speed;

[0026] The status determination module is used to determine that the vehicle is in a state of waiting to start when the vehicle's operating speed is zero.

[0027] The signal generation module is used to generate a corresponding vehicle control signal in response to the starting gear engagement operation, based on a preset gear that matches the starting state.

[0028] The gear control module is used to transmit the vehicle control signal to the motion control unit, and the vehicle control signal is used to instruct the motion control unit to perform an operation corresponding to the preset gear.

[0044] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0045] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, data stored, data displayed, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties, and the collection, use and processing of the relevant data must comply with relevant regulations.

[0046] The gear control method provided in this application embodiment can be applied to, for example, Figure 1The illustrated application environment includes a gear position controller 120 and a motion control unit 140. The gear position controller 120 and the motion control unit 140 can communicate via electrical connection, bus, or local area network. The gear position controller 120 may include a memory and a processor. The memory stores the computer program corresponding to the gear position control logic, and the processor executes the computer program to perform the following gear position control operations. The motion control unit 140 provides the power required for vehicle operation, driving the vehicle's movement.

[0047] Specifically, the gear position controller 120 can acquire the current vehicle speed. When the vehicle speed is zero, the gear position controller 120 can determine that the vehicle is in a ready-to-start state. In response to the starting gear engagement operation, the gear position controller 120 generates a corresponding vehicle control signal based on a preset gear that matches the ready-to-start state, and sends the vehicle control signal to the motion control unit 140. The vehicle control signal is used to instruct the motion control unit 140 to perform the operation corresponding to the preset gear.

[0048] In this embodiment, by adding a gear controller to the vehicle, when the vehicle is in a state of waiting to start, the gear controller can directly generate a corresponding vehicle control signal based on a preset gear that matches the state of waiting to start. This enables the vehicle to operate in the preset gear during the starting process, thereby effectively ensuring that the clutch wear caused during the starting process is at a low level and extending the service life of the clutch.

[0049] In one exemplary embodiment, such as Figure 2 As shown, a gear control method is provided, which is applied to... Figure 1 Taking the gear position controller 120 as an example, the explanation includes the following steps S202 to S208. Wherein:

[0050] Step S202: Obtain the current vehicle speed.

[0051] Optionally, in some embodiments, the gear position controller can acquire signals from the vehicle's instrument panel. The current vehicle speed is determined based on the speed signal from the instrument panel. Alternatively, in other embodiments, the gear position controller can be connected to a vehicle speed sensor to determine the current vehicle speed by acquiring real-time signals from the vehicle speed sensor.

[0052] Step S204: When the vehicle speed is zero, determine that the current vehicle is in a state of waiting to start.

[0053] The "waiting to start" state can be used to characterize a vehicle that is stationary and about to start moving.

[0054] For example, since the vehicle's operating speed is zero when it starts, the gear controller can determine that the vehicle is in a state of waiting to start when it detects that the vehicle's operating speed is zero.

[0055] In step S206, in response to the starting gear engagement operation, a corresponding vehicle control signal is generated based on the preset gear that matches the starting state.

[0056] The preset gear can be used to represent a gear that reduces clutch wear during vehicle start-up. For example, the preset gear can be the lowest gear, or it can be any gear less than three.

[0057] For example, the gear position controller may store preset gears that match the state before starting. In response to a starting gear engagement operation, the gear position controller can generate a corresponding vehicle control signal based on the preset gears that match the state before starting. The starting gear engagement operation may be triggered by detecting whether the vehicle engine is running, or by detecting whether a mechanical lever is moved, or by detecting whether the handbrake or clutch is moved.

[0058] Step S208: The vehicle control signal is sent to the motion control unit. The vehicle control signal is used to instruct the motion control unit to perform the operation corresponding to the preset gear.

[0059] For example, the gear position controller can send vehicle control signals to the motion control unit so that the motion control unit, after receiving the vehicle control signals, performs an operation corresponding to a preset gear, such as adjusting the engine speed to match the preset gear, or generating power corresponding to the preset gear.

[0060] In the above gear control method, by acquiring the current vehicle speed, when the vehicle speed is detected to be zero, it is determined that the current vehicle is in a state of waiting to start. In response to the starting gear engagement operation, a corresponding vehicle control signal is generated according to the preset gear that matches the state of waiting to start. The vehicle control signal is sent to the motion control unit, which is then used to instruct the motion control unit to perform the operation corresponding to the preset gear. This allows the vehicle to start in a fixed preset gear during the starting process, thereby avoiding the large wear on the clutch caused by starting in a non-preset gear and effectively extending the service life of the clutch.

[0061] In an exemplary embodiment, the gear control method provided in this application may further include: acquiring the gear information of the current mechanical lever, and continuing to send vehicle control signals to the motion control unit when the gear information does not match the preset gear.

[0062] For example, the gear position controller can be connected to the vehicle's mechanical lever. The gear position controller can obtain the current gear position information of the mechanical lever in real time. If the actual gear position information of the mechanical lever does not match the currently used preset gear, the gear position controller can continue to send vehicle control signals generated according to the preset gear to the motion control unit.

[0063] Optionally, in some implementations, regardless of the actual gear position information of the mechanical handle, the gear position controller can respond to the starting gear engagement operation by generating a corresponding vehicle control signal based on a preset gear that matches the state to be started.

[0064] In this embodiment, by obtaining the actual gear position information of the current mechanical lever, if the actual gear position information of the mechanical lever does not match the preset gear position that matches the starting state, the vehicle control signal generated according to the preset gear position is continued to be used. This can avoid the problem of increased clutch wear caused by the driver shifting the mechanical lever to a higher gear during the vehicle starting process, and achieve the purpose of stabilizing the vehicle start at the preset gear position to reduce clutch wear.

[0065] In one exemplary embodiment, the gear control method provided in this application may further include:

[0066] If the gear information does not match the preset gear, a gear position prompt message is generated based on the gear information and the preset gear. The gear position prompt message is sent to the visual interface for display, and is used to instruct the mechanical handle to be adjusted to the gear position that matches the preset gear.

[0067] For example, if the actual gear position information of the mechanical lever does not match the preset gear position that matches the starting state, the gear position controller can generate corresponding gear position prompt information based on the actual gear position information of the mechanical lever and the preset gear position. The gear position controller can send the gear position prompt information to a visual interface to prompt the driver to adjust the mechanical lever to the gear position that matches the preset gear position.

[0068] In this embodiment, by prompting the driver to adjust the mechanical gear to a preset gear position that matches the starting state during vehicle start-up, it can help improve the driver's gear-shifting habits when starting.

[0069] In one exemplary embodiment, such as Figure 3 As shown, the gear control method provided in this application may further include the following steps S302 to S306. Wherein:

[0070] Step S302: If the gear information matches the preset gear, continue to acquire the real-time gear information of the mechanical handle.

[0071] Step S304: When the real-time gear information changes, a corresponding real-time control signal is generated based on the real-time gear information.

[0072] Step S306: The real-time control signal is sent to the motion control unit. The real-time control signal is used to instruct the motion control unit to perform the operation corresponding to the real-time gear information.

[0073] For example, when the gear position controller detects that the current gear position information of the mechanical handle matches a preset gear position, it can continue to acquire the real-time gear position information of the mechanical handle. If a change in the real-time gear position information of the mechanical handle is detected, the gear position controller can generate a corresponding real-time control signal based on the current real-time gear position information of the mechanical handle. This real-time control signal is then sent to the motion control unit, so that the motion control unit, upon receiving the real-time gear position signal, performs the operation corresponding to the real-time gear position information.

[0074] In this embodiment, when the actual gear information of the mechanical handle matches the preset gear that matches the starting state, a new real-time control signal is generated by detecting the actual real-time gear information of the mechanical handle. The motion control unit is then controlled to perform the operation corresponding to the real-time gear information using the real-time control signal, which improves the flexibility of gear control.

[0075] In an exemplary embodiment, the motion control unit may further include a transmission controller and an engine electronic control unit. Step S208 described above may include:

[0076] Vehicle control signals are sent to the transmission controller, which instructs the transmission controller to adjust the engine torque output based on a preset gear. Vehicle control signals are also sent to the engine electronic control unit, which instructs the engine electronic control unit to control the engine to produce operating power matching a preset gear.

[0077] For example, the gear position controller can be connected to both the transmission controller and the engine electronic control unit (ECU). The gear position controller can transmit a vehicle control signal generated based on a preset gear to the transmission controller, instructing the transmission controller to adjust the engine torque output to match the preset gear upon receiving the vehicle control signal. The gear position controller can also transmit the vehicle control signal generated based on the preset gear to the ECU, instructing the ECU to control the engine to generate operating power matching the preset gear.

[0078] In this embodiment, by using a gear position controller to control the transmission controller and engine electronic control unit based on the vehicle control signal generated by the preset gear, it can be ensured that the transmission and engine operate in the preset gear during vehicle start-up, thereby effectively extending the service life of the clutch.

[0079] In one exemplary embodiment, the preset gear can be the lowest gear in the forward gears of a manual transmission vehicle.

[0080] In this embodiment, by responding to the starting gear engagement operation and generating a corresponding vehicle control signal based on the first gear that matches the starting state, the problem of rapid wear and failure of the transmission clutch plate caused by starting the vehicle in a gear other than the first gear can be avoided, thereby achieving the technical effect of extending the service life of the clutch plate.

[0081] In one exemplary embodiment, such as Figure 4 As shown, a gear control method is also provided, including the following steps S402 to S418. Wherein:

[0082] Step S402: Obtain the current vehicle speed.

[0083] Step S404: When the vehicle speed is zero, determine that the current vehicle is in a state of waiting to start.

[0084] In step S406, in response to the starting gear engagement operation, a corresponding vehicle control signal is generated based on the preset gear that matches the starting state.

[0085] Step S408: The vehicle control signals are transmitted to the transmission controller and the engine electronic control unit, respectively.

[0086] The preset gear is first gear.

[0087] For example, the gear position controller can obtain the current vehicle speed through a vehicle speed sensor. When the vehicle speed is zero, it is determined that the vehicle is in a state of waiting to start. In response to the starting gear engagement operation, regardless of the actual gear information of the mechanical lever, the controller performs an operation to generate a corresponding vehicle control signal based on a preset gear that matches the state of waiting to start. The vehicle control signal is sent to the transmission controller and the engine electronic control unit, respectively, to instruct the transmission controller to adjust the engine torque output based on the preset gear, and to instruct the engine electronic control unit to control the engine to generate operating power matching the preset gear.

[0088] Step S410: Obtain the current gear position information of the mechanical handle.

[0089] Step S412: If the gear information matches the preset gear, continue to acquire the real-time gear information of the mechanical handle.

[0090] Step S414: When the real-time gear information changes, a corresponding real-time control signal is generated based on the real-time gear information, and the real-time control signal is sent to the transmission controller and the engine electronic control unit respectively.

[0091] Step S416: If the gear information does not match the preset gear, generate a gear prompt message based on the gear information and the preset gear.

[0092] Step S418: Continue to send vehicle control signals to the transmission controller and engine electronic control unit, and send gear position information to the visual interface for display.

[0093] For example, the gear position controller can obtain the current actual gear position information through a mechanical handle. If the gear position information matches the preset gear position, steps S412 to S414 are executed to generate a new real-time control signal based on the actual real-time gear position information of the mechanical handle. The real-time control signal is then sent to the transmission controller and the engine electronic control unit, respectively, to instruct the transmission controller to adjust the engine torque output based on the real-time gear position information, and to instruct the engine electronic control unit to control the engine to generate operating power that matches the real-time gear position information.

[0094] If the gear information does not match the preset gear, the operations of steps S416 to S418 are performed. Based on the current gear information and the preset gear, a gear prompt message is generated and sent to the visual interface for display. The vehicle control signal continues to be sent to the transmission controller and the engine electronic control unit to instruct the transmission controller to adjust the engine torque output based on the preset gear, and to instruct the engine electronic control unit to control the engine to generate operating power that matches the preset gear.

[0095] In this embodiment, the vehicle's current starting state is determined based on its operating speed. In response to the starting gear engagement operation, a corresponding vehicle control signal is generated based on the preset gear (i.e., first gear) that matches the starting state. This vehicle control signal is then transmitted to the transmission controller and the engine electronic control unit, ensuring the vehicle starts in the preset gear with minimal wear, avoiding the significant wear caused by starting in a different gear, thus effectively extending the clutch's lifespan. After the vehicle starts, the actual gear position information of the mechanical lever continues to be monitored. If the gear position information matches the preset gear, a new real-time control signal is generated in response to subsequent changes in the real-time gear position information to control the vehicle, improving the flexibility of gear control and meeting the driver's needs. If the actual gear position information of the mechanical lever does not match the preset gear, the vehicle control signal matching the preset gear continues to be used for vehicle motion control, and a gear position indicator prompts the driver to return the mechanical lever to the preset gear. This avoids driving hazards caused by sudden gear changes, improving the safety and stability of vehicle operation.

[0096] It should be understood that although the steps in the flowcharts of the embodiments described above are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the embodiments described above may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least a portion of the steps or stages of other steps.

[0097] Based on the same inventive concept, this application also provides a gear control device for implementing the gear control method described above. The solution provided by this device is similar to the solution described in the above method; therefore, the specific limitations in one or more gear control device embodiments provided below can be found in the limitations of the gear control method described above, and will not be repeated here.

[0098] In one exemplary embodiment, such as Figure 5 As shown, a gear control device 500 is provided, including: a speed acquisition module 502, a state determination module 504, a signal generation module 506, and a gear control module 508, wherein:

[0099] Speed ​​acquisition module 502 is used to acquire the current vehicle speed.

[0100] The state determination module 504 is used to determine that the vehicle is in a state of waiting to start when the vehicle speed is zero.

[0101] The signal generation module 506 is used to generate a corresponding vehicle control signal in response to the starting and shifting operation, based on a preset gear that matches the starting state.

[0102] The gear control module 508 is used to transmit vehicle control signals to the motion control unit, which instructs the motion control unit to perform an operation corresponding to a preset gear.

[0103] In an exemplary embodiment, the gear control device 500 further includes: a gear acquisition module, used to acquire the gear information of the current mechanical handle; and to continue to send vehicle control signals to the motion control unit if the gear information does not match the preset gear.

[0104] In an exemplary embodiment, the gear position acquisition module is further configured to: continue to acquire the real-time gear position information of the mechanical handle when the gear position information matches the preset gear position; generate a corresponding real-time control signal based on the real-time gear position information when the real-time gear position information changes; and transmit the real-time control signal to the motion control unit, wherein the real-time control signal is used to instruct the motion control unit to perform an operation corresponding to the real-time gear position information.

[0105] In an exemplary embodiment, the gear position acquisition module is further configured to: generate gear position prompt information based on the gear position information and the preset gear position when the gear position information does not match the preset gear position; and send the gear position prompt information to a visual interface for display, wherein the gear position prompt information is used to instruct the mechanical handle to be adjusted to a gear position that matches the preset gear position.

[0106] In one exemplary embodiment, the motion control unit includes a transmission controller and an engine electronic control unit. The gear position control module 508 is further configured to transmit vehicle control signals to the transmission controller, which instructs the transmission controller to adjust the engine torque output based on a preset gear; and to transmit vehicle control signals to the engine electronic control unit, which instructs the engine electronic control unit to control the engine to generate operating power matching the preset gear.

[0107] In one exemplary embodiment, the preset gear is first gear.

[0108] Each module in the aforementioned gear control device 500 can be implemented entirely or partially through software, hardware, or a combination thereof. These modules can be embedded in or independent of the processor in a computer device, or stored in the memory of a computer device as software, so that the processor can call and execute the operations corresponding to each module.

[0109] In one exemplary embodiment, such as Figure 6 As shown, a vehicle 600 is provided, including: a mechanical handle 620, a transmission controller 640, an engine electronic control unit 660, an engine 680, and a gear position controller 120. The gear position controller 120 is connected to the mechanical handle 620, the transmission controller 640, and the engine electronic control unit 660.

[0110] For example, the gear position controller 120 can be used to acquire the current vehicle speed of the vehicle 600. When the vehicle speed is zero, it is determined that the current vehicle 600 is in a ready-to-start state. In response to the start-up gear engagement operation, a corresponding vehicle control signal is generated according to a preset gear that matches the ready-to-start state. The vehicle control signal is sent to the engine electronic control unit 660 and the transmission controller 640.

[0111] The transmission controller 640 is used to adjust the torque output of the engine 680 based on a preset gear when a vehicle control signal is received.

[0112] The engine electronic control unit 660 is used to control the engine 680 to generate operating power that matches the preset gear when it receives a vehicle control signal.

[0113] In this embodiment, by adding a gear position controller to the vehicle, all mechanical gear positions of the mechanical lever are connected to the gear position control signal. The gear position controller then performs logic processing to generate corresponding control signals, which are sent to the transmission control and engine electronic control units to execute the operation corresponding to the gear position of the control signal. This ensures that the vehicle starts in a preset gear, avoiding rapid clutch wear caused by starting in a non-preset gear, thereby extending the clutch's service life.

[0114] Alternatively, in some implementations, such as Figure 7As shown, the gear position controller 120 includes a processor 702, a memory 704, an input / output interface 706 (I / O), a communication interface 708, and a system bus 710. The processor 702, memory 704, and I / O interface 706 are connected via the system bus 710, and the communication interface 708 is connected to the system bus 710 via the I / O interface 706. The processor 702 of the gear position controller 120 provides computing and control capabilities. The memory 704 of the gear position controller 120 includes a non-volatile storage medium and internal memory. The non-volatile storage medium stores the operating system, computer programs, and a database. The internal memory provides an environment for the operation of the operating system and computer programs in the non-volatile storage medium. The database of the gear position controller 120 stores data such as vehicle speed, preset gear, and vehicle control signals. The I / O interface 706 of the gear position controller 120 is used for information exchange between the processor 702 and external devices. The communication interface 708 of the gear position controller 120 is used to communicate with an external terminal via a network connection. When the computer program is executed by the processor 702, it implements a gear position control method.
