Redundancy management method and system based on double hot backup system, and enhanced auxiliary driving system

The invention relates to a redundancy management method and system and an enhanced auxiliary driving system. The redundancy management method comprises the following steps: judging whether a main channel and a slave channel are in a fault state or not; entering a master/slave dual-channel working mode under the condition that both the master channel and the slave channel are in a fault-free state; entering a single-channel working mode under the condition that any one of the main channel and the slave channel is in a fault state; under the condition of entering the single-channel working mode, judging whether the fault channel is recovered to a fault-free state or not; under the condition that the fault channel cannot be recovered to the fault-free state, the single-channel working mode is maintained; and under the condition that the fault channel is recovered to the fault-free state, the single-channel working mode is switched to the master/slave dual-channel working mode. The method has the advantages that
