The invention is suitable for the field of a new energy automobile and discloses a fault processing method for an electric automobile. The fault processing method comprises the following steps of A, receiving fault information of parts and judging the fault information by a complete vehicle controller; B, performing fault type division to the fault information of the complete vehicle; C, performing security level classification to the faults of different parts; D, according to the present state information of the parts, judging the fault thresholds of the main signals to prevent from oversensitive processing; E, according to the fault information and state signal ranges of the parts, allocating fault codes of the complete vehicle to each fault; F, dividing various faults into multiple ranks and processing the faults by the complete vehicle controller according to driving experience. According to the fault processing method, persons, the vehicle and parts can be ensured in safety; when the faults are occurred, the driving function of the vehicle can be as far as possible maintained; besides the fault safety rank can be fully considered, and the faults are not roughly processed, thereby ensuring safety and driving experience of the complete vehicle.
