Abstract

The embodiment of the invention provides a firmware upgrading method and system, a vehicle and a storage medium, and relates to the field of automobiles. The method comprises the following steps: configuring an electronic control unit into at least two independent partitions by responding to a firmware upgrading request, determining one of the at least two independent partitions as a running partition, and determining the other partitions as idle partitions; determining a target idle partition from the idle partitions; acquiring a firmware package corresponding to the target idle partition; and responding to the partition switching request, and switching the running partition and the target idle partition to install the firmware package, so that the to-be-updated firmware can be updated to the electronic control unit under the condition that the use of the vehicle is not influenced, the non-inductive upgrading of the firmware is realized, and the user experience is improved.

Description

technical field [0001] The embodiments of the present application relate to the field of automobiles, and in particular, to a firmware upgrade method, system, vehicle, and storage medium. Background technique [0002] With the rise of the Internet of Vehicles technology, firmware over-the-air (OTA) technology is gradually installed in vehicles, so as to realize functions such as the integration of new vehicle functions, the upgrade of existing functions, and the repair of problems. [0003] When using the traditional OTA solution to upgrade the to-be-upgraded module, the to-be-upgraded module cannot operate normally, which limits the use of the vehicle and affects the vehicle experience. In addition, other existing sensorless OTA solutions require hardware to support the address remapping function, which has many limitations. SUMMARY OF THE INVENTION [0004] Embodiments of the present application provide a firmware upgrade method, system, vehicle, and storage medium to i...
