In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The invention provides a vehicle-mounted software management system, which comprises a vehicle-mounted end and a server end, wherein the vehicle-mounted end comprises:
the vehicle-mounted end stores the fixed data packet and receives the configurable data packet sent by the server end;
the server side stores the configurable data packets and sends the corresponding configurable data packets to the vehicle-mounted side according to different input condition parameters;
wherein the content of the first and second substances,
the fixed data packet is an immutable general function module;

and the vehicle-mounted end is used for carrying out vehicle-mounted software management and control by combining the fixed data packet and the configurable data packet.
Under certain conditions of vehicle-mounted hardware resources, vehicle-mounted local process programs and the like, when the data volume or algorithm calculation amount is too large and the local resource requirements are too much to meet, complex tasks of optimizing and refining data and algorithms are placed in a server side, so that the local hardware resources and algorithm resources are saved, and the local resources occupied by generating an optimal configuration data packet are reduced.
Optionally, the server is a host factory server or an ethernet cloud.
Under the condition of ensuring vehicle-mounted safety, a vehicle-mounted process program is divided into a default program and a configurable program, the default program corresponds to a fixed data packet, and the configurable program corresponds to a configurable data packet, wherein the configurable data packet can be modified and updated to meet different requirements of the vehicle process program.
The data packet can be a sub-function module component in software, and can be understood as a sub-model in Simulink software.
Configurable data includes, but is not limited to, generic packets, regional packets, and replaceable custom packets.
The configurable data packet is a data packet in different environments in the host factory server, and the data accuracy in specific road conditions is superior to that of a traditional vehicle.
Furthermore, the vehicle-mounted end collects real-time information such as road conditions and environments and feeds the information back to the server end;
and the server side updates and optimizes the data of the configurable data packet according to the information such as the road condition environment and the like fed back by the vehicle-mounted side.
The special driving path of the user can be calculated by using the server side through an optimization algorithm, and after the vehicle-mounted side receives the updated configurable data packet, the performance of the vehicle is better.
Furthermore, when the vehicle-mounted end detects a special driving path of the vehicle, for example, under a complex road condition, if the road conditions of the user vehicle repeatedly driving are similar, and the driving times reach a certain condition, the vehicle-mounted end sends the collected user data to the server end to be calculated through an optimization algorithm, so as to form an optimal configuration data packet which can be continuously changed.
Furthermore, the server side adopts an optimization algorithm of the machine learning algorithm model to update and optimize the data of the configurable data packet.
The input condition parameters of the server side, including actual scene parameters and user operation switching instructions, are collected and sent to the server side through the vehicle-mounted side.
And the server side selects the corresponding configurable data packet according to the environment switching and sends the configurable data packet to the vehicle-mounted side, associates the function with the environment change and optimizes the vehicle-mounted performance.
And the actual scene parameters comprise actual road conditions, and the configurable data packet of the vehicle-mounted end is switched at any time through the real-time road conditions to form optimal vehicle-mounted process management software.
And communication and data transmission are carried out between the vehicle-mounted end and the server end in the modes of Ethernet, Bluetooth and radio frequency.
The ethernet method includes but is not limited to wifi, 4G, 5G and other communication methods.
With the increase of the number of requests of the vehicle-mounted terminal, the computing capability of the server terminal is possibly limited. Under the preset condition, the server side can pack the optimization algorithm model and the corresponding operation data, encrypt the data and send the encrypted data to a third party, and the third party provides operation capacity according to an interface in a way of agreement or lease.
The preset conditions include, but are not limited to, the following cases:
1) the number of the simultaneously accessed vehicle-mounted terminals is large and exceeds a threshold value;

Fig. 1 discloses a schematic diagram of a conventional on-board software management system in the prior art, such as the on-board software management system of a conventional vehicle Car10 shown in fig. 1, wherein ECUs 10-ECU1n are conventional on-board controllers, and n is the number of the on-board controllers.
Wherein, the data packet corresponding to each vehicle-mounted controller is not classified, for example:
the data packets of the on-board controller ECU10, including data packets a10, B10, C10, D10;
the data packets of the vehicle-mounted controller ECU1m comprise data packets A1m, B1m and C1m, wherein m is less than or equal to n;
the packets of the on-board controller ECU1n include packets A1n, B1n, and C1 n.
If the data packets of the vehicle controller ECU10 and the ECU1n are simply integrated, the data packets are as follows: a10, B10, C10, D10, A1n, B1n and C1n, and the difference between the data amount before and after integration is not large.
Fig. 2 is a schematic diagram of an in-vehicle software management system according to an embodiment of the present invention, and the in-vehicle software management system shown in fig. 2 classifies and integrates conventional data packets, and networks a part of the data packets to form data packets of an in-vehicle controller, which include fixed data packets and configurable data packets.
In this embodiment, the server is a mainframe server 200, which is a background for the mainframe factory to provide services to users, and the services provided include providing configurable data packets.
As shown in FIG. 2, the same vehicle corresponds to two states of Car21 and Car22 under different working environments, and the vehicle-mounted controllers formed by the classification and integration of the vehicle-mounted software management system are ECU20-ECU2 m.
The original vehicle-mounted controller ECU10 and the ECU1n are integrated into the vehicle-mounted controller ECU20 as an example.
In the present embodiment, the ECU10 is a vehicle controller, and the ECU1n is a motor controller.
The data packets of the on-board controller ECU20 include a20, B20, C20, D20, E20.
A20, B20 and C20 are modules for universal diagnosis, network management and the like, are fixed parts in the integrated function of the original ECU10 and the ECU1n and serve as fixed data packets, and the fixed data packets are stored in the vehicle-mounted end of the vehicle;
d20 and E20 are unique function modules of the original ECU10 and the ECU1n respectively, D20 is a unique algorithm module of the whole vehicle controller, and E20 is a unique algorithm module of the motor controller, and the unique algorithm modules are used as configurable data packets and stored in a host factory server.
The vehicle-mounted controller ECU20 formed by integrating the original vehicle-mounted controller ECU10 and the ECU1n has a large data volume.
According to the invention, the data packets are divided into the fixed data packets and the configurable data packets, the configurable data packets are divided into smaller functional algorithm modules, the huge data packets are partially divided, the divided data of each part are subjected to fine capacity expansion, the unique data packets D20 and E20 … are used as the configurable data packets and are placed in the server of the host factory, and the problem of resource limitation of the vehicle-mounted controller of the local vehicle-mounted end is solved in a network resource mode of the server end.
The default calibration data of the fixed data packet stored at the vehicle-mounted end is the universal data, and if the fixed data packet required by a user is more, capacity expansion can be performed by providing a local data hardware interface, for example, by expanding a U disk.
And the risk of switching all road conditions and untimely signals is notified to the vehicle-mounted end user in a collaborative mode.
As shown in FIG. 2, host factory server 200 stores configurable data packages ECUSJ20 for ECU20, including but not limited to the following:
general packets D20, E20;
plateau data packets D20, F20;
mountain land packets G20, H20;
custom packets X20, Y20, etc.
The plateau data packets D20 and F20 and the mountain data packets G20 and H20 are regional data packets, the custom data packets X20 and Y20 are identical to D20 and E20 when vehicles are delivered, and optimization and updating are carried out through intersection environment information in the subsequent use process.
The data packets can be configured to be placed in the mainframe factory server 200 in different usage scenarios, and the local vehicle-mounted terminal can be regarded as a typical application of the data packets corresponding to a specific optimization algorithm in different scenarios with respect to the mainframe factory server 200.
Under the condition that refined data is not changed, part of information of the configurable data packet is placed in the server side, the fixed configuration packet of the vehicle-mounted side is smaller than that of a traditional vehicle, working condition judgment logics of different use scenes are drawn into the host factory server 200 for carrying out, and the running performance of a program corresponding to the configurable data packet received by the vehicle-mounted side is better.
All the data information of the configurable data packet, the host factory server 200 can use the quantized data to send to the vehicle-mounted end, and can achieve the best risk prompt according to different road conditions.
When the vehicle enters different environments and the network of the vehicle-mounted end can access the host factory server 200, the vehicle-mounted end sends the actual scene parameters or the user operation switching instruction to the host factory server 200.
And the host factory server 200 switches the configurable data packet and sends the configurable data packet to the vehicle-mounted terminal according to a system automatic instruction or a vehicle owner operation switching instruction generated by the actual scene parameters.
For example, when the vehicle drives into a mountain environment, the vehicle-mounted end sends the mountain environment parameters to the host factory server;
the host factory server selects mountain data packets G20 and H20 of the configurable data packet ECUSJ20 according to the input mountain environment parameters and sends the mountain data packets G20 and H20 to the vehicle-mounted terminal;
configurable data packets of the ECU20 on the vehicle-mounted side are switched to mountain data packets G20 and H20, and the vehicle-mounted side is switched from the Car21 state to the Car22 state.
Due to the inconsistent data packet requirements of the vehicle controllers in different vehicle condition environments, when no configurable data packet capable of exactly matching the actual environment is found, the configurable data packet selected by the host factory server 200 is the preset general data packet D20, E20.
During the peak access period of the host factory server 200, if the vehicle-mounted end user needs to perform checking computation of complex data, the host factory server 200 may package the optimization algorithm model of the controller and the corresponding operation data, encrypt and send the result to the ethernet cloud platform 300 or a third party of another network platform for collaborative computation.
The agreement mode is not fixed, and can be queuing/paying to preempt the Ethernet resource.
The ethernet cloud platform 300 performs a functional service of real-time traffic conditions in a purchasing or leasing manner.
The host factory server 200 can be configured as a configurable data packet interface with universality, regionality, customization and the like under the condition of ensuring vehicle-mounted safety, and different interfaces correspond to different configuration data packets.
Further, regional data packets include local (sales sites) and foreign data packets.
In the embodiment shown in fig. 2, the custom data packets X20 and Y20 are optimized and updated by the optimization algorithm provided by the host factory server or the ethernet platform under the contract of the host factory after the vehicle-mounted end performs multiple actual road condition acquisitions through the custom interface provided by the host factory server, and the custom data packets can be continuously and slightly adjusted subsequently according to the user habits.
The number of times of actual road condition acquisition at the vehicle-mounted end can be preset, and optionally, the specified acquisition number of times is 100.
After the vehicle-mounted end is networked, each networked vehicle is an input end in the optimization algorithm of the environmental data of the host factory server 200, under the operational capability provided by the host factory server 200, the data volume collected under different road conditions is exponentially increased and fed back to the optimization algorithm of the host factory server 200, so that the data and the algorithm are closer to each real data, and the performance of the vehicle-mounted end is better.
In this embodiment, the optimization algorithm of the host factory server is a machine learning algorithm, and further, may be a deep learning algorithm.
All local data collection and optimization presents the characteristics of Ethernet and artificial intelligence deep learning, and finally the optimal configurable data packet is fed back to the vehicle-mounted end user in an exponential mode.
The vehicle-mounted software management system provided by the invention has the following beneficial effects:
1) the optimal data under different environments can be switched in real time according to the environments;
2) the complex algorithm and the accurate data can be sent to a server side for processing, so that local resources are saved;
3) all local data acquisition and optimization presents Ethernet and artificial intelligence characteristics, and finally the optimal data is fed back to the vehicle-mounted end user in an exponential mode.
