[0028] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0029] It should be noted that the terms "base", "initial", "target", "original", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0030] Calibration refers to the process of adjusting or optimizing the internal parameters of the ECU according to the performance requirements of the ECU or the performance requirements of the vehicle. In the prior art, calibration engineers use calibration tools such as CANAPE and INCA on the test bench and the actual vehicle, interact with the running ECU under the support of a specific communication protocol, and adjust or optimize the internal parameters of the ECU according to the performance requirements of the ECU or the performance requirements of the vehicle to achieve the calibration process, thereby improving the power, safety, stability and other performance of the vehicle. Afterwards, the calibration amount is downloaded to the calibration area in the flash memory (FLASH) area to retain the valid calibration results.

[0031] In the prior art, the calibration engineer will issue a program download command through the human-computer interaction interface provided by the host computer calibration tool, such as CANAPE, and then the host computer will issue an instruction to erase the memory area of ​​the relevant calibration quantity through the FLASH erase and erase function provided by the Universal Measurement and Calibration Protocol (XCP), and continue to send instructions to write the corresponding calibrated calibration quantity to the calibration area in the FLASH area, thereby realizing the calibration data download function. However, the calibration tool requires the host computer to provide a human-computer interaction interface to issue observation and change instructions for variables to the ECU; it is necessary to implement human-computer interaction according to protocols such as the bus calibration protocol (CAN Calibration Protocol, CCP), ECP or ETK; it is necessary to correspond to the variable address, data and calibration details in the database according to the executable file or calibration description file; it is necessary to convert the host computer command into bus data through the calibration tool; it is necessary to rely on data links such as the Controller Area Network (CAN), CAN with Flexible Data-Rate (CANFD), and the Internet. However, when the ECU is in an offline state, the ECU will be disconnected from the hardware device and cannot complete the calibration data storage by relying on the calibration tool or debugger of the host computer. Therefore, in order to reduce the dependence on the calibration tool or debugger of the host computer during the calibration data storage process and improve the development efficiency of the electronic control unit, an embodiment of the present invention provides a calibration data storage method in an offline state.
