AI Technical Summary

Technical Problem

Existing automotive OTA upgrade technologies suffer from problems such as unstable upgrade processes, low success rates, long processing times, poor user experience, and insufficient security. They are particularly prone to interruptions or failures in complex vehicle operating environments, and the large size of upgrade packages leads to excessive network latency, affecting user experience and posing a risk of network attacks.

Method used

By optimizing pre-upgrade checks, upgrade package verification, installation process, and anomaly recovery mechanisms, and employing differential download technology, A/B partition system design, and multiple security verifications, the system ensures that upgrades are performed under stable conditions and automatically restores to the original state in case of anomalies, thereby improving security and efficiency.

Benefits of technology

It significantly improves the success rate and security of OTA upgrades, shortens upgrade time, improves user experience, and reduces data transmission volume and traffic costs through differential download, ensuring normal vehicle operation during the upgrade process.

Abstract

The application provides an automobile OTA upgrading method and system, and belongs to the technical field of automobile intelligent networking. The method comprises the following steps: preparation before upgrading, receiving an upgrading request at the vehicle end and checking the state of the vehicle, confirming that the preset upgrading condition is met, and downloading an upgrading package from a cloud server; upgrading package verification, verifying the digital signature and checking the integrity of the downloaded upgrading package; upgrading installation, backing up the current system of the vehicle, installing the upgrading package, and checking the installed system; post-upgrading processing, restarting the system after the check passes, and feeding back the upgrading result to the cloud server and the user end. Through systematic state checking, multiple safety verification, A / B partition backup installation and abnormal recovery mechanism, the stability, success rate and safety of the OTA upgrading are effectively improved, the upgrading time is shortened, and the user interaction experience is improved. The application is suitable for remote software updating of various intelligent networked vehicles.
