[0044] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present 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, stored data, displayed data, 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 relevant data must comply with relevant regulations.

[0046] The gear control method provided in the embodiment of the present application can be applied to Figure 1The application environment shown includes a gear controller 120 and a motion control unit 140. The gear controller 120 and the motion control unit 140 can communicate with each other through electrical connection, bus or local area network. The gear controller 120 may include a memory and a processor. The memory stores a computer program corresponding to the gear control logic. The processor implements the following gear control operations when executing the computer program. The motion control unit 140 is used to provide the power required for the vehicle to run and drive the vehicle to move.

[0047] Specifically, the gear controller 120 can obtain the current vehicle running speed. When the vehicle running speed is zero, the gear controller 120 can determine that the current vehicle is in a waiting-to-start state. In response to the starting gear operation, the gear controller 120 can generate a corresponding vehicle control signal according to a preset gear matching the waiting-to-start state, and transmit 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 an operation corresponding to the preset gear.

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

[0049] In an exemplary embodiment, Figure 2 As shown, a gear control method is provided, which is applied to Figure 1 The gear controller 120 in FIG. 1 is taken as an example to illustrate the method, which includes the following steps S202 to S208. Among them:

[0050] Step S202, obtaining the current vehicle running speed.

[0051] Optionally, in some embodiments, the gear controller may obtain a vehicle dashboard signal, and determine the current vehicle running speed according to the running speed signal in the vehicle dashboard signal. Alternatively, in other embodiments, the gear controller may also be connected to a vehicle speed sensor, and determine the current vehicle running speed by collecting a real-time signal from the vehicle speed sensor.

[0052] Step S204: when the vehicle running speed is zero, determine that the vehicle is currently in a waiting-to-start state.

[0053] The waiting-to-start state can be used to represent a state in which the vehicle is stationary and is about to start.

[0054] For example, since the running speed of the vehicle when starting is zero, the gear controller can determine that the current vehicle is in a waiting-to-start state when detecting that the running speed of the vehicle is zero.

[0055] Step S206, in response to the start-up gear shifting operation, a corresponding vehicle control signal is generated according to a preset gear position matching the state to be started.

[0056] The preset gear can be used to represent a gear that can reduce clutch wear during vehicle starting. For example, the preset gear can be the smallest gear, or the preset gear can be any gear less than the third gear.

[0057] Exemplarily, the gear controller may store a preset gear that matches the state to be started. The gear controller may generate a corresponding vehicle control signal in response to the start-up gear operation according to the preset gear that matches the state to be started. The start-up gear operation may be triggered by detecting whether the vehicle engine is started, or by whether the mechanical handle is moved, or by detecting whether the handbrake or the clutch is moved.

[0058] Step S208: transmitting the vehicle control signal to the motion control unit, where the vehicle control signal is used to instruct the motion control unit to perform an operation corresponding to the preset gear position.

[0059] Exemplarily, the gear controller can transmit a vehicle control signal to the motion control unit so that after receiving the vehicle control signal, the motion control unit 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 running speed, when detecting that the vehicle running speed is zero, it is determined that the current vehicle is in a waiting-to-start state, and in response to the starting gear shifting operation, a corresponding vehicle control signal is generated according to a preset gear matching the waiting-to-start state, and the vehicle control signal is transmitted 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, so that the vehicle can be started with a fixed preset gear during the starting process, thereby avoiding the greater wear on the clutch caused by starting with a non-preset gear, and effectively extending the service life of the clutch.

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

[0062] For example, the gear controller may be connected to a mechanical handle of the vehicle. The gear controller may obtain the gear information of the current mechanical handle in real time. When the actual gear information of the mechanical gear does not match the currently used preset gear, the gear controller may continue to transmit the vehicle control signal generated according to the preset gear to the motion control unit.

[0063] Optionally, in some embodiments, regardless of the actual gear information of the mechanical handle, the gear controller can respond to the start-up gear operation and generate a corresponding vehicle control signal according to a preset gear that matches the state to be started.

[0064] In this embodiment, by obtaining the actual gear information of the current mechanical handle, when the actual gear information of the mechanical handle does not match the preset gear that matches the starting state, continue to use the vehicle control signal generated according to the preset gear. This can avoid the problem of increased clutch wear caused by the driver shifting the mechanical handle to a higher gear during the vehicle starting process, thereby stabilizing the vehicle start at the preset gear to reduce clutch wear.

[0065] In an exemplary embodiment, the gear control method provided by the present application may further include:

[0066] In the case where the gear information does not match the preset gear, the gear prompt information is generated according to the gear information and the preset gear, and the gear prompt information is sent to the visualization interface for display, and the gear prompt information is used to instruct the mechanical handle to be adjusted to a gear position that matches the preset gear.

[0067] For example, when the actual gear information of the mechanical handle does not match the preset gear that matches the state to be started, the gear controller can generate corresponding gear prompt information according to the actual gear information of the mechanical handle and the preset gear. The gear controller can send the gear prompt information to the visual interface for display, so as to prompt the driver to adjust the mechanical handle to a gear position that matches the preset gear.

[0068] In this embodiment, during the vehicle starting process, the driver is prompted to adjust the mechanical gear to a gear position that matches the preset gear position that matches the state to be started, which can help improve the driver's starting gear shifting habits.

[0069] In an exemplary embodiment, Figure 3 As shown, the gear control method provided by the present application may also include the following steps S302 to S306. Among them:

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

[0071] Step S304: when the real-time gear position information changes, a corresponding real-time control signal is generated according to the real-time gear position information.

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

[0073] For example, when the gear controller detects that the current gear information of the mechanical handle matches the preset gear, it can continue to obtain the real-time gear information of the mechanical handle. When it is detected that the real-time gear information of the mechanical handle changes, the gear controller can generate a corresponding real-time control signal according to the real-time gear information of the current mechanical handle. The real-time control signal is transmitted to the motion control unit, so that the motion control unit performs the operation corresponding to the real-time gear information when receiving the real-time gear signal.

[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, and the real-time control signal is used to control the motion control unit to perform operations corresponding to the real-time gear information, thereby improving the flexibility of gear control.

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

[0076] The vehicle control signal is transmitted to the transmission controller, and the vehicle control signal is used to instruct the transmission controller to adjust the torque output of the engine based on the preset gear. The vehicle control signal is transmitted to the engine electronic control unit, and the vehicle control signal is used to instruct the engine electronic control unit to control the engine to generate the running power matching the preset gear.

[0077] Exemplarily, the gear controller may be connected to the transmission controller and the engine electronic control unit, respectively. The gear controller may transmit a vehicle control signal generated according to a preset gear to the transmission controller, so as to instruct the transmission controller to adjust the torque output of the engine to match the preset gear after receiving the vehicle control signal. The gear controller may transmit a vehicle control signal generated according to a preset gear to the engine electronic control unit, so as to instruct the engine electronic control unit to control the engine to generate a running power matching the preset gear.

[0078] In this embodiment, by using the gear controller to control the transmission controller and the engine electronic control unit according to the vehicle control signal generated by the preset gear, it can be ensured that during the vehicle starting process, the transmission and the engine operate according to the preset gear, thereby effectively extending the service life of the clutch.

[0079] In an exemplary embodiment, the preset gear may be the lowest forward gear of a manual transmission vehicle.

[0080] In this embodiment, by responding to the starting and shifting gear operation, a corresponding vehicle control signal is generated according to the first gear that matches the starting state, which can avoid the problem of rapid wear and failure of the transmission clutch plate caused by the vehicle starting in a non-first gear, thereby achieving the technical effect of extending the service life of the clutch plate.

[0081] In an exemplary embodiment, Figure 4 As shown, a gear control method is also provided, including the following steps S402 to S418. Among them:

[0082] Step S402, obtaining the current vehicle running speed.

[0083] Step S404: when the vehicle running speed is zero, determine that the vehicle is currently in a waiting-to-start state.

[0084] Step S406, in response to the start-up gear shifting operation, a corresponding vehicle control signal is generated according to a preset gear position matching the state to be started.

[0085] Step S408, transmitting the vehicle control signal to the transmission controller and the engine electronic control unit respectively.

[0086] Among them, the preset gear is first gear.

[0087] Exemplarily, the gear controller can obtain the current vehicle running speed of the vehicle through the vehicle speed sensor. When the vehicle running speed is zero, it is determined that the current vehicle is in the waiting-to-start state. In response to the starting gear operation, regardless of the actual gear information of the mechanical handle, an operation of generating a corresponding vehicle control signal according to a preset gear matching the waiting-to-start state is performed. The vehicle control signal is transmitted to the transmission controller and the engine electronic control unit respectively to instruct the transmission controller to adjust the torque output of the engine based on the preset gear, so as to instruct the engine electronic control unit to control the engine to generate the running power matching the preset gear.

[0088] Step S410, obtaining the gear information of the current mechanical handle.

[0089] Step S412: When the gear information matches the preset gear, continue to obtain 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 according to the real-time gear information, and the real-time control signal is transmitted to the transmission controller and the engine electronic control unit respectively.

[0091] Step S416: when the gear information does not match the preset gear, generate gear prompt information according to the gear information and the preset gear.

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

[0093] For example, the gear controller can obtain the current actual gear information through the mechanical handle. When the gear information matches the preset gear, the operation of step S412 to step S414 is performed, and a new real-time control signal is generated according to the actual real-time gear information of the mechanical handle, and the real-time control signal is transmitted to the transmission controller and the engine electronic control unit respectively, so as to instruct the transmission controller to adjust the torque output of the engine based on the real-time gear information, so as to instruct the engine electronic control unit to control the engine to generate the running power matching the real-time gear information.

[0094] When the gear information does not match the preset gear, the operations of step S416 to step S418 are executed, gear prompt information is generated according to the current gear information and the preset gear, the gear prompt information is sent to the visualization interface for display, and the vehicle control signal is continued to be transmitted to the transmission controller and the engine electronic control unit to instruct the transmission controller to adjust the torque output of the engine based on the preset gear, so as to instruct the engine electronic control unit to control the engine to generate operating power matching the preset gear.

[0095] In this embodiment, by judging whether the vehicle is currently in the waiting-to-start state according to the vehicle running speed, in response to the starting gear operation, a corresponding vehicle control signal is generated according to the preset gear (i.e., the first gear) matching the waiting-to-start state, and the vehicle controllability is transmitted to the transmission controller and the engine electronic control unit respectively, so that the vehicle can be ensured to start at the preset gear with less wear, and avoid the phenomenon of large wear caused by starting in non-first gear, thereby effectively extending the service life of the clutch. After the vehicle starts, by continuing to detect the actual gear information of the mechanical handle, when the gear information matches the preset gear, in response to the subsequent real-time gear information change, a corresponding new real-time control signal is generated to control the vehicle, which can improve the flexibility of gear control and meet the driving needs of the driver. In the case that the actual gear information of the mechanical handle does not match the preset gear, the vehicle control signal matching the preset gear is continued to be used to control the vehicle movement, and the driver is prompted to return the mechanical handle to the preset gear through the gear prompt information, which can avoid the driving danger caused by the sudden change of the gear and improve the safety and stability of the vehicle operation.

The implementation scheme for solving the problem provided by the device is similar to the implementation scheme recorded in the above method, so the specific limitations in one or more gear control device embodiments provided below can refer to the limitations of the gear control method above, and will not be repeated here.

[0099] The speed acquisition module 502 is used to acquire the current vehicle running speed.

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

The gear controller 120 is connected to the mechanical handle 620, the gearbox controller 640 and the engine electronic control unit 660 respectively.

[0110] For example, the gear controller 120 can be used to obtain the current vehicle running speed of the vehicle 600.

In response to the starting gear operation, a corresponding vehicle control signal is generated according to a preset gear matching the waiting state.
