[0014] If the parameter information is of the non-state parameter type, then the parameter information is stored in the vehicle controller.

[0015] Optionally, after determining the type of the parameter information, the method further includes:

[0016] If the parameter information is of the type of status parameter, then the parameter information is stored in the vehicle's cockpit controller.

[0017] Optionally, the status parameter is used to control the opening and closing of controls associated with the preset function, and determining the type of the parameter information includes:

[0018] The system detects whether the control has a self-reset function; the self-reset function describes the control performing an initialization operation each time the vehicle is powered on; the initialization operation of the control includes the initialization operation of the state parameters;

[0019] If the preset control does not have the self-reset function, then the type of the parameter information is determined.

[0020] Optionally, after storing the parameter information in the vehicle's cockpit controller, the method further includes:

[0021] Obtain the user information of the vehicle;

[0022] The cockpit controller associates and stores the parameter information and user information, and sends the parameter information and user information to the server for association and storage.

[0023] Optionally, after storing the parameter information in the vehicle's vehicle controller, the method further includes:

[0024] When the vehicle is detected to be powered on again, the parameter information is read from the vehicle controller and sent to the vehicle's cockpit controller.

[0025] The cockpit controller is controlled to perform operations corresponding to the preset functions according to the parameter information.

[0026] Secondly, embodiments of this application provide a parameter storage device for an in-vehicle terminal, comprising:

[0027] The first acquisition unit is used to acquire parameter setting requests for preset functions of the vehicle; the parameter setting requests carry parameter information corresponding to the preset function and the number of controllers associated with the preset function;

[0028] The first storage unit is used to store the parameter information to the vehicle controller if the quantity is greater than one.

[0033] The beneficial effects of the embodiments in this application compared with the prior art are:

[0034] This application provides a parameter storage method for an in-vehicle terminal. The method involves obtaining a parameter setting request for a preset function of a vehicle. The parameter setting request carries parameter information corresponding to the preset function and the number of controllers associated with the preset function. If the number is greater than one, the parameter information is stored in the vehicle's overall controller. Compared to existing technologies where multiple controllers are associated with a preset function, requiring each parameter to be stored separately in each controller, the method provided in this application directly stores all parameter information in the vehicle's overall controller. This eliminates the need for the in-vehicle terminal to search for each controller associated with the preset function or to confirm the correspondence between the parameter information and each associated controller. Instead, all parameter information is stored in a single controller—the overall vehicle controller—rather than in their individual controllers. This shortens the parameter storage process for the in-vehicle terminal, simplifying operation and improving processing efficiency. Attached Figure Description

[0048] Please see Figure 1 , Figure 1 This is a flowchart illustrating the implementation of a parameter storage method for an in-vehicle terminal according to an embodiment of this application. In this embodiment, the in-vehicle terminal is the executing entity of the parameter storage method for the in-vehicle terminal.

[0049] like Figure 1 As shown, a parameter storage method for an in-vehicle terminal provided in one embodiment of this application may include S101 to S102, which are described in detail below:

[0050] In S101, a parameter setting request for a preset function of the vehicle is obtained; the parameter setting request carries parameter information corresponding to the preset function and the number of controllers associated with the preset function.

[0051] In practical applications, when a vehicle user needs to configure a certain function of the vehicle, they can send a parameter setting request for the preset function to the in-vehicle terminal. The preset function can be set according to actual needs and is not limited here. For example, the preset function could be a driving mode selection function or a welcome function, etc.

[0052] In this embodiment, the vehicle terminal detecting a user's request to set parameters for a preset function of the vehicle can be achieved by detecting a preset operation on the vehicle terminal. The preset operation can be set according to actual needs and is not limited here. For example, the preset operation could be clicking a preset app on the vehicle terminal's display interface or clicking a preset control within a preset app. Based on this, when the vehicle terminal detects that the preset control has been clicked, it determines that a preset operation has been detected, i.e., a user's request to set parameters for a preset function of the vehicle has been detected.

[0053] After receiving the above parameter setting request, the vehicle terminal can extract the parameter information corresponding to the preset function and the number of controllers associated with the preset function from the parameter setting request.

[0054] It should be noted that the controller associated with the preset function is used to characterize the controller that needs to be used when implementing the preset function.

[0055] The parameter information corresponding to the preset function refers to the specific parameter values ​​executed by the controller associated with the preset function when the vehicle implements the preset function. For example, assuming the preset function is the air conditioning adjustment function, and the parameter information corresponding to the air conditioning adjustment function is to increase the air conditioning temperature by 2 degrees, then the air conditioning controller associated with the air conditioning adjustment function can control the vehicle's air conditioning temperature to increase by 2 degrees.

[0056] In this embodiment of the application, after obtaining the number of controllers associated with the preset function, the vehicle terminal can detect whether the number of controllers associated with the preset function is greater than one.

[0057] In one embodiment of this application, the vehicle terminal can execute step S102 when it detects that the number of controllers associated with a preset function is greater than one.

[0058] In another embodiment of this application, when the vehicle terminal detects that the number of controllers associated with a preset function is equal to one, the vehicle terminal may specifically perform the following: Figure 2 The steps S201 to S203 are shown.

[0059] In S102, if the number is greater than one, the parameter information is stored in the vehicle controller of the vehicle.

[0060] In this embodiment, when the vehicle terminal detects that the number of controllers associated with the preset function is greater than one, it indicates that there are multiple controllers associated with the preset function, that is, multiple controllers need to work together to achieve the preset function. Therefore, in order to avoid storing parameter information in each corresponding controller, resulting in uneven distribution of parameter information in each controller of the vehicle and increasing the occurrence of related system software changes and maintenance caused by function changes, the vehicle terminal can store all parameter information corresponding to the preset function in the vehicle's whole vehicle controller.

[0061] It should be noted that the aforementioned vehicle controller can be a vehicle-level controller, that is, a controller used to control the entire vehicle. For example, a vehicle-level controller can be a central computing unit or a controller with a system-on-a-chip (SOC).

[0062] In this embodiment, the types of parameter information corresponding to the preset function include, but are not limited to, status parameters and non-status parameters. Among them, status parameters are used to control the opening and closing of controls associated with the preset function. These controls can be various switches.

[0063] Based on this, in one embodiment of this application, the vehicle terminal can specifically be implemented as follows: Figure 3 The execution steps S102 shown in S301 to S302 are detailed below:

[0064] In S301, the type of the parameter information is determined.

[0065] In S302, if the parameter information is of the type of non-state parameter, then the parameter information is stored in the vehicle controller.

[0066] In this embodiment, the vehicle terminal can determine the type of parameter information based on the attributes of the parameter information.

[0067] The parameters include, but are not limited to, a first attribute and a second attribute. The first attribute indicates that the parameters are used to control the opening and closing of the control, and the second attribute indicates that the parameters are used to control the opening degree of the control.

[0068] In some possible embodiments, when the attribute of the parameter information is the first attribute, the parameter information can be represented by the numbers "0" and "1". Here, the number "0" represents the control being turned on, and the number "1" represents the control being turned off.

[0069] Parameter information can also be represented by the words "OFF" and "ON".

[0070] When the attribute of the parameter information is the second attribute, the parameter information can be represented by a specific numerical value and an increment / decrement sign. For example, assuming the preset function is the air conditioning adjustment function, +5 can represent an increase of 5 degrees in the air conditioning temperature.

[0071] In this embodiment, when the vehicle terminal determines that the parameter information is a non-state parameter, it can store the parameter information in the vehicle controller.

[0072] In one embodiment of this application, when the vehicle terminal determines that the type of parameter information is a status parameter, the vehicle terminal can store the parameter information in the vehicle's cockpit controller.

[0073] In another embodiment of this application, when the control associated with the preset function has a self-reset function, that is, the control performs an initialization operation every time the vehicle is powered on, that is, the control is restored to its initial state. In other words, even if the state parameters of the control are stored, the control still needs to reset the state parameters after the vehicle is powered on again. Therefore, in order to improve the processing efficiency of the vehicle terminal and avoid the vehicle terminal from performing invalid work, the vehicle terminal can specifically perform step S301 through the following steps, which are detailed below:

[0074] The system detects whether the control has a self-reset function; the self-reset function describes the control performing an initialization operation each time the vehicle is powered on; the initialization operation of the control includes the initialization operation of the state parameters;

[0075] If the preset control does not have the self-reset function, then the type of the parameter information is determined.

[0076] In this embodiment, the vehicle terminal can determine whether the control associated with the preset function has a self-reset function through a server with which it is wirelessly connected.

[0077] Based on this, when the vehicle terminal determines that the above control does not have a self-reset function, it means that the control will not perform an initialization operation each time the vehicle is powered on, that is, the control will not be restored to the initial state. Therefore, at this time, the vehicle terminal can determine the type of parameter information and determine the controller storing the parameter information based on the type.

[0078] As can be seen from the above, the parameter storage method for an in-vehicle terminal provided in this application obtains a parameter setting request for a preset function of the vehicle. The parameter setting request carries parameter information corresponding to the preset function and the number of controllers associated with the preset function. If the number is greater than one, the parameter information is stored in the vehicle's whole controller. Compared with the prior art, when there are multiple controllers associated with the preset function, each parameter corresponding to the preset function needs to be stored separately in each controller. The method provided in this application can directly store all parameter information in the vehicle's whole controller when there are multiple controllers associated with the preset function. This eliminates the need for the in-vehicle terminal to search for each controller associated with the preset function or to confirm the correspondence between the parameter information corresponding to the preset function and each associated controller. Instead, all parameter information is directly stored in one controller, i.e., the whole controller, rather than in their respective controllers. This shortens the parameter information storage process for the in-vehicle terminal, making the operation simpler and improving processing efficiency.

[0079] Please see Figure 2 , Figure 2 This is another embodiment of the parameter storage method for an in-vehicle terminal provided in this application. Compared to... Figure 1 In a corresponding embodiment, this embodiment may further include S201 to S203 after S101, as detailed below:

[0080] In S201, if the quantity is equal to one, the type of storage device in the controller associated with the preset function is detected.

[0081] In this embodiment, when the vehicle terminal detects that the number of controllers associated with the preset function is one, it indicates that there is only one controller associated with the preset function, that is, only one controller is needed to realize the preset function. Therefore, in order to identify the controller that stores the parameter information corresponding to the preset function and improve the success rate of storing the parameter information so that the vehicle can directly realize the preset function after powering on again without resetting, the vehicle terminal can detect the type of storage device in the controller associated with the preset function.

[0082] It should be noted that the types of storage devices include, but are not limited to, volatile memory and non-volatile memory.

[0083] Volatile memory refers to memory that loses data after power failure, while non-volatile memory refers to memory that does not lose data after power failure.

[0084] Based on this, in this embodiment, when the vehicle terminal detects that the type of storage device in the controller associated with the preset function is volatile memory, it can execute step S202.

[0085] When the vehicle terminal detects that the type of storage device in the controller associated with the preset function is non-volatile memory, it can execute step S203.

[0086] In S202, if the type of the storage device is volatile memory, the parameter information is stored in the vehicle controller.

[0087] In this embodiment, when the vehicle terminal detects that the type of storage device in the controller associated with the preset function is volatile memory, it indicates that the storage device in the controller associated with the preset function is a memory that will lose data after power failure. Therefore, in order to avoid loss of parameter information and improve user experience, the vehicle terminal can store the parameter information in the vehicle controller.

[0088] In S203, if the type of the storage device is non-volatile memory, the parameter information is stored in the controller associated with the preset function.

[0089] In this embodiment, when it is detected that the type of storage device in the controller associated with the preset function is non-volatile memory, it indicates that the storage device in the controller associated with the preset function is a memory that will not lose data after power failure. Therefore, the vehicle terminal can directly store parameter information in the controller associated with the preset function.

[0090] In one embodiment of this application, in order to improve user experience and avoid loss of parameter information, the vehicle terminal specifically performs the following steps, detailed below:

[0091] Obtain the user information of the vehicle;

[0092] The parameter information is sent to the cockpit controller, which then associates and stores the parameter information with the user information. Finally, the parameter information and the user information are sent to the server for associated storage.

[0093] In this embodiment, user information includes, but is not limited to, the user's facial image and fingerprint information.

[0094] In one implementation of this embodiment, the vehicle terminal can acquire in real time the facial image of the user who sends a parameter setting request for preset functions of the vehicle to the vehicle terminal through a camera device that is wirelessly connected to it.

[0095] In another implementation of this embodiment, the vehicle terminal can obtain the fingerprint information of the user who sends a parameter setting request for the vehicle's preset functions to the vehicle terminal in real time through a fingerprint acquisition device that is wirelessly connected to it.

[0096] Based on this, the vehicle terminal can send the parameter information stored in the controller associated with the preset function to the vehicle's cockpit controller, and control the cockpit controller to associate and store the parameter information and user information, and then send the parameter information and user information to a server wirelessly connected to the vehicle terminal for association and storage.

[0097] As can be seen from the above, the parameter storage method for vehicle terminals provided in this embodiment, if the number is equal to one, detects the type of storage device in the controller associated with the preset function; if the type of storage device is volatile memory, the parameter information is stored in the vehicle controller; if the type of storage device is non-volatile memory, the parameter information is stored in the controller associated with the preset function. When the method provided in this embodiment detects that there is only one controller associated with the preset function, it needs to determine the controller used to store the parameter information based on the type of storage device of the controller associated with the preset function. This can improve the success rate of storing parameter information and prevent the loss of the parameter information after the controller is powered off, so that the preset function can be directly implemented after the vehicle is powered on again without resetting, thereby improving the user experience.

[0098] Please see Figure 4 , Figure 4 This is another embodiment of the parameter storage method for an in-vehicle terminal provided in this application. Compared to... Figure 1 In a corresponding embodiment, this embodiment may further include S401 to S402 after S102, as detailed below:

[0099] In S401, the user information of the vehicle is obtained.

[0100] In S402, the cockpit controller is controlled to associate and store the parameter information and the user information, and then send the parameter information and the user information to the server for associated storage.

[0101] In this embodiment, user information includes, but is not limited to, the user's facial image and fingerprint information.

[0102] In one implementation of this embodiment, the vehicle terminal can acquire in real time the facial image of the user who sends a parameter setting request for preset functions of the vehicle to the vehicle terminal through a camera device that is wirelessly connected to it.

[0103] In another implementation of this embodiment, the vehicle terminal can obtain the fingerprint information of the user who sends a parameter setting request for the vehicle's preset functions to the vehicle terminal in real time through a fingerprint acquisition device that is wirelessly connected to it.

[0104] Based on this, the vehicle terminal can control the vehicle's cockpit controller to associate and store parameter information and user information, and send the parameter information and user information to a server that is wirelessly connected to the vehicle terminal for association and storage.

[0105] As can be seen from the above, the parameter storage method for in-vehicle terminals provided in this embodiment can obtain vehicle user information after storing the parameter information in the vehicle's cockpit controller; control the cockpit controller to associate and store the parameter information and user information, and send the parameter information and user information to the server for associated storage. The method provided in this embodiment associates and stores parameter information and user information so that the vehicle can subsequently obtain the corresponding parameter information based on the user information of different users using the vehicle, thereby improving the user experience. At the same time, sending the parameter information and user information to the server for associated storage avoids data loss.

[0106] In one embodiment of this application, after storing the parameter information to the vehicle's controller, the vehicle terminal may further perform the following steps, detailed below:

[0107] When the vehicle is detected to be powered on again, the parameter information is read from the vehicle controller and sent to the vehicle's cockpit controller.

[0108] The cockpit controller is controlled to perform operations corresponding to the preset functions according to the parameter information.

[0109] In this embodiment, when the vehicle terminal detects that the vehicle is powered on again, since the parameter information is stored in the vehicle's whole vehicle controller, in order to control the vehicle to implement the preset functions, the vehicle terminal can read the parameter information corresponding to the stored preset functions from the vehicle's whole vehicle controller and send the parameter information to the vehicle's cockpit controller.

[0110] Then, the vehicle terminal can control the cockpit controller to perform the operation corresponding to the preset function according to the parameter information received for the preset function, so as to realize the preset function.

[0111] As can be seen from the above, the parameter setting method for the vehicle terminal provided in this embodiment can send the parameter information to the cockpit controller after storing the parameter information in the vehicle controller and detecting that the vehicle is powered on again. This allows the cockpit controller to execute the operation corresponding to the preset function according to the parameter information. After the user starts the vehicle, the vehicle terminal can directly realize the preset function according to the stored parameter information without the user having to set the preset function again, thereby improving the user experience.

[0112] The method of this application will be described in detail below with a specific example. The background of this example is that the preset function is a personalized function (including seat adjustment and steering wheel adjustment).

[0113] First, when a user needs to set personalized functions, they can adjust the seat and steering wheel in the vehicle. When the in-vehicle terminal detects that the seat and steering wheel are being used, it indicates a request for setting parameters for the personalized functions. Therefore, the in-vehicle terminal can obtain the first parameter after the seat is adjusted and the second parameter after the steering wheel is adjusted. Since the controllers associated with the aforementioned personalized functions include the cockpit controller and the steering wheel controller (i.e., the number of associated controllers is greater than one), the terminal device can store both the first and second parameters in the vehicle's overall controller.

[0114] Subsequently, after detecting that the vehicle is powered on again, the vehicle terminal can directly obtain the first and second parameters from the vehicle controller and send them to the cockpit controller so that the cockpit controller can adjust the seat according to the first parameter and adjust the steering wheel controller connected to it according to the second parameter.

[0115] In one implementation, the terminal device can obtain the user's information, namely, the user's facial image information or fingerprint information, and associate the first parameter and the second parameter with the user information for storage, so that when the user uses the vehicle again, the vehicle's on-board terminal can directly adjust the vehicle's seat and steering wheel according to the first parameter and the second parameter associated with the user information.

[0116] It should be understood that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.
