The invention relates to a vehicle-mounted terminal and a remote upgrading method thereof, and belongs to the technical field of Internet of Vehicles. According to the scheme, when the vehicle-mounted terminal is powered on or reset, bootloader logic is entered, the version of an original app in an app partition and the version of upgrading firmware in a down load partition are compared, if the version of the upgrading firmware in the down load partition is not high, the original app is executed, and when it is detected that the upgrading firmware exists in a file system, the upgrading firmware in the file system is written into the down load partition and reset is conducted; and if the version of the upgrade firmware in the down load partition is high, covering the upgrade firmware in the down load partition into the app partition, executing a new app program, and when it is detected that the upgrade firmware exists in the file system, writing the upgrade firmware in the file system into the down load partition and resetting. According to the method, the process of detecting whether the latest upgrade package is obtained or not is combined with the starting process of the corresponding vehicle-mounted terminal, so that the function of the terminal is not influenced in the vehicle driving process, and the driving process is not influenced.
本发明涉及一种车载终端及其远程升级方法,属于车联网技术领域。方案包括,车载终端上电或复位时,进入bootloader逻辑,比较app分区中原app程序和download分区中升级固件的版本,若不是download分区中升级固件的版本高,则执行原app程序,当检测到所述文件系统中有升级固件,则将所述文件系统中的升级固件写入到download分区并复位;若download分区中升级固件的版本高,将download分区的升级固件覆盖到app分区中,执行新app程序,当检测到所述文件系统中有升级固件,则将所述文件系统中的升级固件写入到download分区并复位。本方法将是否获取到最新升级包的检测过程与相应车载终端的启动过程结合在一起,不会在车辆行驶过程中影响该终端的功能,也不会对驾驶过程造成影响。
