The invention discloses a four-motor distributed control electric drive axle, and belongs to the technical field of electric drive axles, the four-motor distributed control electric drive axle comprises a matrix type four-motor drive unit and two double-path input two-stage speed reducers, the matrix type four-motor drive unit is four small-torque high-speed motors arranged in a matrix mode, and the two double-path input two-stage speed reducers are arranged in the matrix type. The matrix type four-motor driving unit comprises a first matrix type left motor, a second matrix type left motor, a first matrix type right motor and a second matrix type right motor, and output shafts of the first matrix type left motor and the second matrix type left motor are located on one side of the electric bridge. Output shafts of the first matrix type right motor and the second matrix type right motor are located on the other side of the bridge. The electric bridge is applied to a pure electric or hybrid power heavy commercial vehicle, solves the problem of power interruption during gear shifting of a conventional electric bridge, and is very compact, free of offset, light in weight, small in size and convenient for arrangement of the whole vehicle.
