Summary: | The invention relates to a dual-system switching method and system for a new energy automobile, and the method specifically comprises the steps: S1, before a to-be-executed application program runs, a vehicle control unit supplies power to run a safety guide program, recognizes a hardware state, and analyzes the configuration information of the to-be-executed application program; s2, mapping data on the physical address of the application program to a logic address space one by one; and S3, retrieving a logic address space, and skipping a program execution stream to a system needing to be executed. According to the method, the whole vehicle controllers of multiple vehicle types can use the same upgrade package, programs and data are stored in a differential mode, the requirement for Flash space is reduced to the maximum extent, and the hardware design cost of the controller is reduced.
