AI Technical Summary

Technical Problem

The software update process for the vehicle controller may fail due to incompatibility between the APP software and the controller hardware version, including issues such as negative response, writing failure, and controller "freezing".

Method used

Before refreshing, the system reads the user program software information and controller information to be refreshed, and compares whether the user program software version number, controller hardware version number, bootloader software version number and user program software termination address match. If they match, the refresh is performed; otherwise, an error is reported.

Benefits of technology

This effectively avoids refresh failures caused by hardware and software incompatibility, improves the success rate of software refresh and system stability, and ensures the accuracy and security of software updates.

Abstract

The invention provides a method for preventing mistaken refreshing of vehicle-mounted controller software, which comprises the following steps: reading to-be-refreshed user program software information to obtain first comparison information, the first comparison information comprising a user program software version number and a termination address of the user program software; and reading the controller information to obtain second comparison information, wherein the second comparison information comprises a hardware version number of the controller and a bootstrap program software version number of the controller. And if the first comparison information is matched with the second comparison information, refreshing the to-be-refreshed software. By verifying whether the refreshing condition is met or not before refreshing, the problem that the software of the vehicle-mounted controller fails to refresh is solved. The invention further provides a vehicle-mounted controller software mistaken-swiping prevention system. Whether the user program software version number, the hardware version number of the controller, the bootstrap program software version number of the controller and the termination address of the user program software are matched or not is judged by comparing whether the user program software version number, the hardware version number and the bootstrap program software version number are matched or not.
