The invention discloses a safe redundant electric vehicle dual-motor wheel edge driving system. The system comprises a first wheel edge motor, a first speed reducing mechanism, a first wheel, a firsthalf shaft, a second wheel edge motor, a second speed reducing mechanism, a second wheel, a second half shaft and a differential mechanism. The power input end of the first speed reducing mechanism isselectively connected with the first wheel edge motor; one end of the first half shaft is connected with the power output end of the first speed reducing mechanism, and the other end of the first half shaft is connected with the first wheel; the power input end of the second speed reducing mechanism is selectively connected with the second wheel edge motor; the second wheel and the first wheel are symmetrically arranged at the two sides of a vehicle; one end of the second half shaft is connected with the power output end of the second speed reducing mechanism, and the other end of the secondhalf shaft is connected with the second wheel; and one end of the differential mechanism is connected with the power output end of the first speed reducing mechanism, and the other end of the differential mechanism is selectively connected with the power output end of the second speed reducing mechanism. The invention further discloses a control method of the safe redundant electric vehicle dual-motor wheel edge driving system.
