According to the vehicle domain controller safe starting method and system and the storage medium, compared with a traditional domain controller upgrading method, in the power-on starting process of a first control unit, a UCB flashing record is read, a partition where the UCB flashing record is located serves as an operation partition after the first control unit is powered on, and the UCB flashing record is read; assigning a global variable as a partition where the UCB flash record is located; then the second control unit is powered on and started, and an operation partition of the second control unit is determined according to the global variable; the assignment global variable only occurs in the power-on process of the first control unit, and the operation partition of the second control unit depends on the global variable, so that the operation partition of the first control unit and the operation partition of the second control unit are always kept consistent through the method; the situation that the operation partition of the first control unit and the operation partition of the second control unit are contradictory does not occur, and it is guaranteed that operation and updating of the vehicle domain controller can be normally executed.
本申请提出一种车辆域控制器安全启动方法、系统及存储介质,与传统的域控制器升级方法相比,本申请在第一控制单元上电启动过程中,读取UCB刷写记录,以UCB刷写记录所在分区作为此次第一控制单元上电启动后的运行分区,并赋值全局变量为所述UCB刷写记录所在分区;而后第二控制单元上电启动,并依据全局变量决定第二控制单元的运行分区;由于赋值全局变量仅发生在第一控制单元的上电过程中,且第二控制单元的运行分区取决于全局变量,所以通过此方法,第一控制单元和第二控制单元的运行分区会始终保持一致,不会出现第一控制单元和第二控制单元运行分区矛盾的情况,保证了车辆域控制器的运行和更新能够正常执行。
