AI Technical Summary
In the prior art, automatic conversion from C0 level to CN level can only be performed in full or boot mode, and cannot be adapted in the event of RBC communication failure or driving permission is not received, resulting in reduced efficiency and low degree of automation.
By setting the positioning transponder DW and the virtual transponder group VBG in the vehicle-mounted device, the CN-level backup mode is automatically transferred to the CN-level backup mode within the C0-level to CN-level conversion interval using the level conversion information, backup mode closure authorization information and line data information stored in the preset electronic map.
In the event of RBC communication failure or no driving permission is received, it can automatically transfer to the CN-level backup mode, which improves the fault tolerance and availability of on-board equipment for communication failures, and improves the efficiency and automation of line operations.
