Detailed Description
The following presents a simplified summary of the invention in order to provide a basic understanding of the invention. It is not intended to identify key or critical elements of the invention or to delineate the scope of the invention.
For the purposes of brevity and explanation, the principles of the present invention are described herein primarily with reference to exemplary embodiments thereof. However, those skilled in the art will readily recognize that the same principles are equally applicable to all types of data refresh methods and data refresh devices, and that these same principles may be implemented therein, and that any such variations do not depart from the true spirit and scope of the present patent application.
Fig. 1 is a flowchart of a data refreshing method of a vehicle ECU of the present invention.
As shown in fig. 1, the data refreshing method of the vehicle ECU of the present invention includes:
request step S100: transmitting a downloading request for downloading the source data to the ECU, wherein the downloading request comprises a downloading address;
judgment step S200: judging whether the download address contains an application program software address or a nonvolatile memory address; and
refreshing step S300: in the case where it is determined in the determining step S200 that the download address contains an application software address or a nonvolatile memory address, the source data is transmitted to the ECU.
The application software file refers to a source file of software, is generally in binary or 16-system format for the ECU, and is responsible for realizing the upper-layer functions of the ECU after the application software file is downloaded to the ECU.
The application software address refers to the physical address of the software on the internal memory of the ECU, and for the ECU, the software of each module inside has a fixed address, and is generally defined at the beginning of design, similar to the way that a computer operating system is generally installed on a C-disc. When downloading software into an ECU, this refers to downloading the source file of the software to the address where the software corresponds inside the ECU.
In the present invention, as described above, the nonvolatile memory (NVM) is divided into a plurality of areas in an internal memory space of the ECU, each area has a corresponding address, and various software is distributed to play different roles, wherein one area is the area where the nonvolatile memory is located, mainly responsible for data storage, not participating in computation, and the data stored generally include: software parameters, user data, log records of software operations, and the like.
The data refreshing method of the vehicle ECU according to the present invention can enable reuse of the nonvolatile memory by deleting all the history user data in the nonvolatile memory, and therefore, can save hardware costs.
Next, an embodiment of a data refreshing method of a vehicle ECU of the present invention will be described.
Fig. 2 is a flowchart of a data refreshing method of a vehicle ECU according to an embodiment of the present invention.
As shown in fig. 2, the data refreshing method of the vehicle ECU according to an embodiment of the present invention includes the steps of:
step S1: entering a programming session;
step S2: when the ECU has software updating requirements, the updated ECU in the updating direction sends a downloading request for downloading the source data to the ECU, wherein the downloading request comprises a downloading address;
step S3: judging whether the download address contains an application program software address or a nonvolatile memory address, if so, continuing the step S4, and if not, jumping to the step S6;
step S4: transmitting the source data to an address corresponding to the ECU;
step S5: exiting the data transmission;
step S6: the refresh process is suspended.
Wherein the source data is contained in the source file to be downloaded (refreshed) to the ECU, the determination in step S3 as to whether the download address contains an application software address or a non-volatile memory address may be achieved by determining whether the address in the download request contains an application software address or a non-volatile memory address.
In addition, the ECU herein may be a radar of the vehicle, a camera, and an ECU that assists the driving-domain controller.
Fig. 3 is a structural frame diagram of the data refreshing apparatus of the vehicle ECU of the present invention.
As shown in fig. 3, the data refreshing apparatus of a vehicle ECU according to the present invention includes:
a request module 100, configured to send a download request for downloading source data to the ECU, where the download request includes a download address;
a judging module 200, configured to judge whether the download address includes an application software address or a non-volatile memory address; and
and a refresh module 300, configured to transmit the source data to the ECU if the determining module 200 determines that the download address includes an application software address or a non-volatile memory address.
Wherein the download address is contained in the header of the source file.
Wherein, in the case where the judging module 200 judges that the download address does not contain an application software address or a nonvolatile memory address, the refreshing module 300 stops transmitting the source data to the ECU.
The vehicle ECU is any one of a radar, a camera, and an ECU assisting a driving-domain controller of the vehicle.
As one embodiment, the data refreshing device of the vehicle ECU of the present invention may be implemented by changing a refresh boot loader (FBL). The Flush Boot Loader (FBL) is already an existing technical means, which is commonly used to upgrade ECU applications through diagnostic services.
For example, in current ADAS ECU (radar, camera, and assisted-driving-domain controller), application software may be refreshed using a refresh boot loader (FBL)) function. According to such inspiring, in the present invention, reuse of hardware is made possible by adding a new function to the refresh boot loader (FBL) to restore the NVM to factory data, which means that all historical user data can be deleted.
Thus, as one example, the present invention provides a refresh module of an ECU of a vehicle, the refresh module comprising: the refresh boot load module and the application module (optional).
Wherein the refresh boot load module further comprises:
a request sub-module, configured to send a download request for downloading source data to the ECU, where the download request includes a download address;
the judging sub-module is used for judging whether the download address contains an application program software address or a nonvolatile memory address; and
and the refreshing sub-module is used for transmitting the source data to the ECU under the condition that the judging sub-module judges that the download address contains the address of the application program software or the address of the nonvolatile memory.
As described above, by adding a function of refreshing the nonvolatile memory on the basis that the existing ECU supports only application software refreshing, that is, by adding a new function of refreshing the nonvolatile memory to the refresh boot loader (FBL), the nonvolatile memory can be restored to factory data, thereby realizing hardware recycling and saving hardware cost.
Further, the present invention also provides a computer-readable medium having stored thereon a computer program, characterized in that the computer program, when executed by a processor, implements the data refreshing method of the vehicle ECU described above.
The invention also provides a computer device which comprises a storage module, a processor and a computer program stored on the storage module and capable of running on the processor, and is characterized in that the data refreshing method of the vehicle ECU is realized when the processor executes the computer program.
The above examples mainly illustrate the data refreshing method and the data refreshing apparatus of the present invention. Although only a few specific embodiments of the present invention have been described, those skilled in the art will appreciate that the present invention may be embodied in many other forms without departing from the spirit or scope thereof. Accordingly, the present examples and embodiments are to be considered as illustrative and not restrictive, and the invention is intended to cover various modifications and substitutions without departing from the spirit and scope of the invention as defined by the appended claims.
