Embodiment Construction

[0031] In order to explain in detail the technical content, structural features, achieved goals and effects of the technical solution, the following will be described in detail in conjunction with specific embodiments and accompanying drawings.

[0032] see Figure 1 to Figure 3 , this embodiment provides a method to solve the problem that the FOTA upgrade fails and cannot be re-flashed. Specifically, when a certain ECU on the vehicle has a software function upgrade requirement or some software-related bugs need to be repaired, the ECU needs to be upgraded at this time. Send it to the DS server, and the DS server will make an ECU refresh and upgrade compressed package file according to a specific protocol. The ECU refresh and upgrade compressed package file mainly includes the ECU upgrade process file, ECU software upgrade package, upgrade-related demand information, and related safety verification information. Send the upgrade compressed package file to the TSP platform, whic...

Abstract

The invention relates to a method and system for solving the problem that FOTA cannot be re-refreshed after FOTA upgrade failure. The method comprises the steps: partitioning a memory of an ECU (Electronic Control Unit) into a program running region and a program storage region; the DS server sends the ECU refreshing task file to a TSP platform, the TSP platform analyzes a refreshing task file package, and after analysis is completed, the refreshing task file package is sent to an automobile end T-BOX; the vehicle end T-BOX continues to analyze the refreshing task file package, and after analysis is completed, an ECU refreshing process is started; the ECU updates the downloaded software upgrade package to the program storage area, and in the updating process, if the problems of poor network signals, wrong refreshing task file package or wrong refreshing process occur, the refreshing task file in the program storage area cannot be transferred into the program running area for updating within the preset time, so that the situation that the refreshing task file in the program storage area cannot be transferred into the program running area for updating after the FOTA refreshing of the ECU fails can be effectively prevented. And under the condition that the ECU cannot be refreshed again in a short time, the ECU software can keep the current software version and recover the functions of the ECU software, so that the normal use of the vehicle is ensured.

Description

technical field [0001] The invention relates to the technical field of automobile electronic control, in particular to a method for solving the problem of re-flash after FOTA upgrade failure Background technique [0002] In the prior art, when upgrading the software of the central control system of the car, power failure or disconnection may occur, which may lead to the failure of the upgrade of the central control system of the car, resulting in crashes, restarts, and AT failures of the central control system of the car, which have a great impact The reliability of the automotive central control system is greatly reduced, and at the same time, it also brings a huge workload to the after-sales maintenance of the automotive central control system. [0003] In the following documents, you can also find more information related to the above technical solutions: [0004] A Chinese invention patent with the notification number CN 106610840A discloses a firmware over-the-air (FOT...
