Abstract

The invention provides on-board equipment and a dual-system backup method and device of the on-board equipment. The method comprises the following steps: receiving a system upgrade instruction for the on-board equipment, wherein two system regions of the on-board equipment are respectively internally provided with two operation systems which can back up each other; detecting and confirming the currently started first operation system in the two operation systems on the basis of the system upgrade instruction; upgrading the non-started second operation system in the two operation systems, wherein the on-board equipment enters the upgraded second operation system by default when being restarted. According to the dual-system backup method and device, the background backup system can be upgraded while the system is used without affecting the use by a user.

Description

technical field [0001] The invention relates to vehicle-mounted equipment, in particular to a vehicle-mounted equipment and a dual-system backup method and device thereof. Background technique [0002] The operating system of the current vehicle equipment usually uses the Android system. The system installed on the vehicle equipment at the factory is often an older version, and the manufacturer will release a new version of the system from time to time to improve the various functions of the system. . In this regard, for the update of the vehicle-mounted Android system, the method usually adopted in the prior art is: the official release of a new version available for download, and after the user obtains the new version, perform a flash upgrade, or recovery (Recovery) upgrade. [0003] However, there are two problems in the above-mentioned upgrade method. On the one hand, after the user downloads the update package to the vehicle-mounted device, he does not necessarily star...
