Abstract
Description
Technical Field
[0001] This application relates to the field of vehicle controller inspection technology, and more specifically, to an inspection method, apparatus and non-volatile storage medium for vehicle controllers. Background Technology
[0002] The accelerating trend towards software-defined vehicles has led to increasingly frequent vehicle software updates. These updates are mostly performed via bus-based diagnostic flashing. However, this flashing process can result in data tampering or falsification of the flashing file. Therefore, the controller itself should have the function to verify the accuracy of data packets. If the controller cannot verify the tampered data and directly installs the modified data packet, it will significantly impact vehicle functionality. Currently, existing technologies lack methods for verifying the vehicle controller's verification function.
[0003] There is currently no effective solution to the above problems. Summary of the Invention

[0022] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.
[0023] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.
[0024] According to one aspect of the embodiments of this application, a method for inspecting a vehicle controller is provided, comprising: acquiring first target information for flashing the controller, wherein the first target information includes data to be flashed; modifying the first target information to obtain second target information; determining the installation status of the vehicle controller of a target vehicle for the second target information based on the second target information, wherein the installation status includes normal installation and installation failure; and determining whether the vehicle controller is in a normal working state based on the installation status.
[0025] According to an embodiment of this application, a method embodiment for testing a vehicle controller is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.
[0026] Figure 1 This is a testing method for a vehicle controller according to embodiments of this application, such as... Figure 1 As shown, the method includes the following steps:
[0027] Step S101: Obtain the first target information for the flashing controller, wherein the first target information includes the data to be flashed.
[0028] Step S102: Modify the first target information to obtain the second target information.
[0029] Step S103: Determine the installation status of the vehicle controller of the target vehicle for the second target information based on the second target information, wherein the installation status includes normal installation and abnormal installation.
[0030] Step S104: Determine whether the vehicle controller is in normal working condition based on the installation status.
[0031] Through the above steps, the first target information of the flashing controller can be modified to obtain the second target information, and then the second target information can be transmitted to the vehicle controller of the target vehicle. The vehicle controller's working status is determined by the installation status of the second target information, thereby achieving the technical effect of judging whether the vehicle controller has a verification function, and thus solving the technical problem of lacking a method for verifying the vehicle controller's verification function in the prior art.
[0032] Optionally, the installation status of the vehicle controller of the target vehicle with respect to the second target information is determined based on the second target information, and the status of the flashing controller is determined based on the installation status, including: if the installation status of the vehicle controller with respect to the second target information is determined to be normal, the vehicle controller is determined to be in an abnormal working state.
[0033] In the above embodiments, if the vehicle controller is determined to be in an abnormal working state when the second target information is installed normally, it proves that the vehicle controller does not have the function of verifying data packets. The security of the vehicle controller is low, and it is easy to cause a significant impact on the vehicle's functions during the flashing process. It should be replaced or upgraded in time to avoid further losses.
[0034] Optionally, the installation status of the vehicle controller of the target vehicle with respect to the second target information is determined based on the second target information, and the status of the flashing controller is determined based on the installation status, including: if it is determined that the installation status of the vehicle controller with respect to the second target information is abnormal, the vehicle controller is determined to be in normal working condition.
[0035] In the above embodiments, if the vehicle controller is determined to be in normal working condition when the installation status of the second target information is abnormal, it proves that the vehicle controller has the function of verifying data packets. The security of the vehicle controller is high. If there is data tampering or falsification of data in the flashing file during the flashing process, the vehicle controller can identify and stop the flashing process in time, avoiding the significant impact of the tampered data flashing on the vehicle's function, and realizing reasonable risk avoidance during the flashing process.
[0036] Optionally, the first target information is modified to obtain the second target information, including: adding a preset value to the data to be written in the first target information to obtain the second target information.
[0037] In the above embodiments, after obtaining the first target information for the flashing controller, the data to be flashed in the first target information is increased by a preset value to obtain the second target information. The data tampering process that may occur during the flashing process is simulated. The working state of the vehicle controller is determined by the installation status of the second target information on the vehicle controller of the target vehicle. If the vehicle controller installs the second target information normally, the vehicle controller is in an abnormal working state, proving that the vehicle controller does not have the function of verifying data packets. If the installation status of the second target information by the vehicle controller is abnormal, the vehicle controller is in a normal working state, proving that the vehicle controller has the function of verifying data packets, and the security of the vehicle controller is high.
[0038] Optionally, the default value is 1. In addition, the default value can also be selected as 2, 3, 4, etc., as long as it can be ensured that the data to be written in the first target information can be increased by the default value to obtain the second target information.

If the installation status is normal, the vehicle controller is in an abnormal working state; otherwise, the vehicle controller is in a normal working state. In this embodiment, by modifying the first target information flashed by the flashing controller 11 to obtain the second target information, and then transmitting the second target information to the vehicle controller of the target vehicle, the working state of the vehicle controller is determined based on the feedback from the vehicle controller of the target vehicle regarding the installation status of the second target information. This achieves the technical effect of judging whether the vehicle controller has an inspection function, thereby solving the technical problem of the lack of a method for inspecting the vehicle controller's verification function in the prior art.
[0041] Optionally, the modification processing device 12 includes: a data receiving module for receiving first target information; a data unpacking module for disassembling and extracting the first target information; a data tampering module for adding a preset value to the data to be written in the first target information to obtain second target information; a data packaging module for packaging the second target information; and a data sending module for sending the second target information.

The power supply module provides power to the modification processing device 12, making it easy to carry and use independently. Optionally, the modification processing device 12 includes: a CAN transceiver interface and an Ethernet transceiver interface.

[0045] Combination Figure 5As shown, in this embodiment, the data receiving module receives the first target information. The data receiving module can be a CAN data receiving module or an ETH data receiving module. The data decryption module decrypts the first target information. The data tampering module determines whether the second byte of the data to be written is 36. If so, the data unpacking module decomposes and extracts the first target information.

The data unpacking module reassembles the second target information. The data encryption module encrypts the second target information. The data sending module sends the second target information to the vehicle controller.
