Detailed Description
Referring to fig. 1 and fig. 2A and 2B, the system with diversified functions of controller software according to the present invention includes a controller, a master controller, and a bus system, wherein the controller and the master controller are connected and communicate with each other through the bus system, and when the master controller sends a bus data file with function setting information, the controller software establishes a mapping memory area and performs data writing and mapping according to the setting, so that the memory setting in the mapping area replaces the mapped memory setting, so as to enable the currently written data function to take effect. The controller comprises a CPU, a memory, an input/output interface, a shell and the like.
When the main control controller sends a new function setting information data file, the controller software adjusts the content of the mapping memory area to realize function updating, and can recycle and redistribute the released mirror image memory area when the memory configuration is tense.
For example, referring to fig. 3, the controller includes one or more function modules, each function module includes data, and the memory mapping or mirroring refers to selecting a part of the function modules or selecting a part of the data of the function modules to perform memory mapping or mirroring. In actual use, a designer of the controller software generally knows the definition of the data stored in each data address, so that which data needs to be mapped and how many mapped values to place can be generated according to application requirements. For example, the memory segment set by the controller software includes a controller memory data segment 1, a controller memory data segment 2, a controller memory data segment 3, \8230, a controller memory data segment m +1, \8230 \ 8230, a controller memory data segment end-1, and a controller memory data segment end. Wherein m is a natural number > 1; in addition, there is a part of the remaining memory.
The invention can select the mapping of all or part of the data segment memory, namely, the structure copying of all or part of the memory segment of the set data can be carried out, for example, new set data different from the original set data is written into the newly copied memory, and when the functional software program of the controller operates, the new set data is adopted to replace the original set data, and then the controller can show different control characteristics.
Example 1
Referring to fig. 4, when the master controller sends a bus data file with function setting information, the controller software will establish a mapping memory area and perform data writing and mapping according to the setting, so that the memory setting in the mapping area replaces the mapped memory setting, so that the currently written data function becomes effective; at this time, the memory segment used for the original software setting cannot be changed.
When the master controller sends a new function setting information data file, the controller software adjusts the contents of the mapped memory area to implement function update, for example, the remaining memory of the controller may establish a mapped area, i.e., a mapped memory (a memory area of data that needs to change functions according to an actually used function), and a memory segment of the mapped memory may be set, changed, or cleared. The controller software function module comprises a controller memory data segment 1, a controller memory data segment 2, a controller memory data segment 3, a controller memory data segment 8230a controller memory data segment m, a controller memory data segment m +1, a controller memory data segment 8230a controller memory data segment end-1 and a controller memory data segment end, when the main controller sends data, the controller residual memory area establishes a mapping area, and an image is established between the memory segment 1 (copy data) of the mapping memory and the memory data segment 1 (original data) of the controller memory.
When the functional software runs, a method of adopting original data or copy data can be selected, and finally the controller software generates a running result and control characteristics different from the original set.
And when the memory configuration is tense, the released mirror memory area can be recycled and reallocated.
Example 2
The memory mapping mode of the invention can select multiple times of mapping of the data segment memory according to the capacity of the available memory. Referring to fig. 5, after the image is created on the memory segment 1 of the mapped memory, the image is created on the memory segment 2 of the mapped memory according to the method of embodiment 1. The memory segment 1 of the mapping memory and the memory segment 2 of the mapping memory are both copy data.
Example 3
The memory mapping mode of the invention can select the mapping of all or part of the data segment memory according to the capacity of the available memory. Referring to fig. 6, a mapping region is only established for data segments of the original data, i.e., a controller memory data segment 1, a controller memory data segment 2, a controller memory data segment 3, and a controller memory data segment end-1, and referring to embodiments 1 and 2, a memory segment 1 of a mapping memory and a memory segment 2 of a mapping memory are respectively established as mirror images.
Referring to fig. 7, taking vehicle-mounted software as an example, a user selects a required function setting such as a certain function mode through the network device 1, after receiving information, the network and data server 2 sends a corresponding command sequence to the main control controller 3 (vehicle terminal device) according to an agreed communication protocol, and after receiving the command sequence, the main control controller 3 performs handshake, information sending and feedback confirmation with the vehicle controller 4; after receiving the information sequence of the function mode selection command, the vehicle controller 4 establishes a proper mirror image memory according to the information of the command sequence, performs normalization, sorting, data writing and confirmation on the mirror image memory, and finally starts the data mirror image to switch to a new function mode, so that the vehicle 5 shows different control characteristics.
Fig. 8 is a system with diversified functions of controller software for multiple users, where each user sets software functions through a software customization management system according to his own needs, and the functions are uploaded to a database management system of a server, and a functional module and a data segment to be updated are formed through the controller software customization management system. The cloud service control center is used as a main controller to send data to a controller of a target device (for example, the vehicle device 1, \\ 8230; \ 8230; the vehicle device N, N are natural numbers of a relevant user), and referring to any one of the embodiments 1 to 3, after the target device receives an information sequence of the function mode selection command, the target device establishes a proper mirror memory according to the information of the command sequence, and performs ordering, sorting, data writing and confirmation on the mirror memory, and finally starts a data mirror to switch to a new function mode, so that the vehicle shows different control characteristics.

Any equivalent modifications and substitutions to those skilled in the art are also within the scope of the present invention.
