[0043] To facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the relevant drawings. The typical embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this invention belongs. The terms used in the description of the present invention herein are for the purpose of describing specific embodiments only and are not intended to limit the present invention.

[0045] The general idea of the present invention is as follows: In view of the problem in the prior art that writing the data upload configuration scheme into the TCU cannot meet the requirements of the complexity and diversity of vehicle data, the present invention configures the vehicle data upload configuration file through a cloud server. According to user requirements, vehicle data to be uploaded is added thereto, and at the same time, the data types of the vehicle data are defined, and the vehicle data is classified into key data and ordinary data; for ordinary data, its upload period and data packaging method are set to perform periodic upload, so as to realize the effective utilization and management of data, and at the same time reduce the frequency and cost of data transmission; for key data, its trigger condition is set, and when it meets the trigger condition, it is immediately uploaded to the cloud server to ensure the timeliness and integrity of the data; thus, the types and upload methods of the uploaded vehicle data can be configured according to different requirements, meeting the requirements of the complexity and diversity of vehicle data, and increasing the diversity and flexibility of the data uploaded by the TCU.

[0046] To better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings of the specification and specific embodiments. It should be understood that the embodiments of the present invention and the specific features in the embodiments are detailed descriptions of the technical solution of the present application, rather than limitations on the technical solution of the present application. Without conflict, the technical features in the embodiments of the present invention and the embodiments can be combined with each other.

[0047] Figure 1 The figure shows a flowchart of a data upload method for an in-vehicle TCU provided by an embodiment of the present invention. As Figure 1 shown, the data upload method for the in-vehicle TCU includes the following steps:

[0048] Step S1, receive configuration information from the cloud server, and update the vehicle data upload configuration file according to the configuration information;

[0049] Specifically, in an embodiment of the present invention, on the cloud server, an administrator can configure the types of data that the in-vehicle TCU can upload according to needs. These data types can include vehicle status data (such as vehicle speed, engine speed, fuel consumption, etc.), driving behavior data (such as acceleration, braking force, steering angle, etc.), environmental data (such as temperature, humidity, air pressure, etc.), and other diagnostic and fault information. At the same time, the administrator can also specify the upload period of each type of data (i.e., the frequency of data upload), the data packaging method (i.e., packaging the data within a certain period of time into a data packet for upload), and the data type (i.e., ordinary data or key data). Next, the cloud server sends these configuration information to the in-vehicle TCU. When the in-vehicle TCU is awakened, it will receive these configuration information and update its own vehicle data upload configuration file according to the configuration information. This configuration file contains the detailed settings for vehicle data upload, including the data types to be uploaded, the upload period, and the packaging method, etc. By updating the configuration file, the in-vehicle TCU can upload data according to the latest configuration requirements.

[0050] In this embodiment, the administrator can configure the types and types of data uploaded by the in-vehicle TCU according to actual needs, and flexibly adjust the upload period and packaging method to adapt to different application scenarios and requirements. At the same time, through the communication between the cloud server and the in-vehicle TCU, remote management and update of the data upload configuration are realized, improving the flexibility and maintainability of the system. By receiving the configuration information from the cloud server and updating the vehicle data upload configuration file, fine control and optimization of vehicle data upload are achieved, providing a basis for subsequent data upload and processing.

[0051] Further, in this embodiment, after receiving the configuration information from the cloud server, it also includes the step of verifying the configuration information. After the verification passes, the vehicle data upload configuration file is updated using the configuration information. Specifically, when the cloud server sets the configuration information, it calculates the first digest of the configuration information using an encryption algorithm, and then signs the digest to obtain a digital signature; then it sends the configuration information and the signature to the in-vehicle TCU; after receiving it, the in-vehicle TCU calculates the second digest of the configuration information using the same encryption algorithm; then it decrypts the digital signature to obtain the first digest, and compares the first digest and the second digest. If the two digests are the same, it means that the configuration information has not been tampered with and the verification passes, and the in-vehicle TCU will use the configuration information to update its own vehicle data upload configuration file.

[0052] In this embodiment, by verifying the configuration information, malicious attacks and data tampering can be effectively prevented, improving the security and reliability of the entire system. At the same time, by using encryption technologies such as digital signatures, the confidentiality and non-forgeability of the configuration information can be ensured, further enhancing the security and reliability of the system.

[0053] Step S2: According to the vehicle data upload configuration file, collect the corresponding vehicle data;

[0054] Specifically, in an embodiment of the present invention, after waking up, when the in-vehicle TCU wakes up from the sleep state, it will determine which vehicle data needs to be collected according to the updated vehicle data upload configuration file and perform the corresponding data collection work. For example, if the configuration file stipulates that data such as vehicle speed, engine speed, and vehicle position need to be collected, then the in-vehicle TCU will collect and store these data respectively.

[0055] Step S3: Determine the data type of the collected vehicle data. If the collected vehicle data is ordinary data, the process proceeds to step S4; if the collected vehicle data is key data, the process proceeds to step S5;

[0056] Specifically, in an embodiment of the present invention, in the vehicle data upload configuration file, the data type of each type of data is distinguished, and the data is classified into key data and ordinary data, and different data upload strategies are executed for key data and ordinary data. Among them, key data refers to data with special importance or sensitivity in vehicle data, and these data may have an important impact on aspects such as vehicle safety, performance, and operating status. For example, vehicle location information: including the real-time location and driving trajectory of the vehicle, these data can be used for functions such as monitoring the vehicle's location, navigation, and positioning, but may also involve user privacy and security issues; driving behavior data: including data such as vehicle speed, acceleration, braking force, and steering angle, which can be used for analyzing driving behavior and providing driving suggestions, and these data are very important for ensuring traffic safety and improving driving efficiency; vehicle diagnostic data: including engine status, fault codes, sensor data, etc., which can be used for detecting the vehicle's health status and predicting faults, and these data are crucial for vehicle maintenance and repair. Ordinary data refers to data that is relatively unimportant or insensitive in vehicle data, and these data may not be directly related to aspects such as vehicle safety, performance, and operating status. For example, driving data: such as driving mileage, fuel consumption, working hours, etc.; environmental data: such as temperature, humidity, air pressure, etc.

[0057] Step S4: When the collected vehicle data is ordinary data, upload the ordinary data to the cloud server periodically according to the configuration information of the vehicle data upload configuration file.

[0058] Specifically, in this embodiment, for ordinary data, since its importance and sensitivity are relatively low, a periodic upload method is generally adopted to reduce the frequency and cost of data upload. At the same time, according to specific application requirements and system scale, different upload strategies and cycles can be set to maximize the utilization efficiency and management level of data. After the ordinary data is collected, it first needs to be classified and stored according to the data type and stored in a dedicated ordinary data storage area; then, according to the configuration information in the vehicle data upload configuration file, further settings are made for the ordinary data. Among them, the configuration information includes the upload cycle and the data upload packaging method. The upload cycle determines the time interval for uploading ordinary data and can be flexibly set according to specific requirements to balance the real-time performance and cost of data upload. The data upload packaging method determines how to package the ordinary data for easy transmission and processing; when the set upload time is reached, the ordinary data is packaged according to the data upload packaging method and uploaded to the cloud server. Therefore, step S4 includes:

[0059] Step S41: Store the ordinary data in the ordinary data storage area;

[0060] Step S42: Configure the upload cycle and the data upload packaging method for the ordinary data according to the vehicle data upload configuration file;

[0061] Step S43: When the upload time is reached, package and upload the ordinary data according to the data upload packaging method.

[0062] In this embodiment, the ordinary data can be regularly uploaded from the vehicle end to the cloud server according to the set upload cycle to achieve the effective utilization and management of data. Periodic upload can reduce the frequency and cost of data transmission, and can also be flexibly adjusted according to the system scale and application requirements to improve the utilization efficiency of data.

[0063] Step S5: When the collected vehicle data is key data, upload the key data to the cloud server when the key data meets the trigger condition according to the configuration information in the vehicle data upload configuration file

[0064] In this embodiment, for key data, a real-time upload method is generally adopted to ensure the timeliness and integrity of the data. Therefore, step S5 includes:

[0065] Step S51: Store the key data in the key data storage area;

[0066] Specifically, in this embodiment, during the data collection process, by classifying and screening the vehicle data, the specific type of data that meets the key data is stored in a dedicated key data storage area.

[0067] Step S52: Determine whether the key data meets the set threshold. When the key data meets the set threshold, add a trigger flag to the key data, start timing simultaneously, and keep it from sleeping during the timing period.

[0068] Specifically, in this embodiment, in the vehicle data upload configuration file, we set a threshold for determining whether the key data meets the upload conditions. The threshold can be set according to specific requirements, such as a specific value or a combination of multiple conditions. In this step, the system will judge the key data. If it meets the set threshold, a trigger flag will be added to the key data, and a timer will be started. The addition of the trigger flag can be achieved by adding a specific identifier or flag bit to the key data. At the same time, to ensure the timeliness of data upload, the system will start a timer and keep the TCU in a working state during the timing period to prevent the system from sleeping. For example, taking vehicle speed as an example: within a certain period of time, if the vehicle speed is traveling at a constant speed and the change in vehicle speed does not meet the threshold conditions, the vehicle speed will not be uploaded in real time; when within a short period of time, the change in vehicle speed is very large and meets the threshold conditions, a trigger flag will be added to the vehicle speed.

[0069] Step S53: Upload the key data with the trigger flag added to the cloud server, and record the trigger times simultaneously.

[0070] Specifically, in this embodiment, once the trigger flag is added, the system will immediately upload the key data with the trigger flag to the cloud server. After the upload is completed, the system will record the trigger times of this data upload for subsequent analysis and statistics.

[0071] Through the above steps, the key data can be uploaded to the cloud server in real time when it meets the set threshold. This real-time upload method can ensure the timeliness and integrity of important data to meet the requirements of data monitoring, analysis, and application. At the same time, recording the trigger times also provides important reference information for subsequent data processing and decision-making, and can be used for data analysis, fault troubleshooting, and optimization and improvement work.
