Electronic gear shifter failure solution method and system

The invention relates to an electronic gear shifter failure solution method and system. The system is a software system mounted on an electronic gear shifter MCU and comprises a finished vehicle traveling information input module, a key input module, a gear position induction input module, a vehicle current gear signal receiving module, a finished vehicle signal receiving module, a gear shifting request logic module, a failure diagnosis module, a control single output module, a gear shifting request signal output module, a failure diagnosis information output module, a failure mode identification module, a failure mode gear shifting request module, a failure mode quit module and a gear shifting request signal output module. By means of the electronic gear shifter failure solution method and system, when an electronic gear shifter is in failure, entry and relief of the failure mode can be set; a gear shifting position signal can be transmitted under the electronic gear shifter failure mode; and a vehicle in fa
