Stability control method of distributed electric drive automobile on split road surface working condition

The invention discloses a stability control method of a distributed electric drive automobile on a split road surface working condition, which comprises the following steps of: comparing an actual tire cornering force with a tire cornering force inflection point value, and judging a working area where each tire of the automobile is located; if the tires of the four wheels of the vehicle are all located in the linear working area and the tires do not excessively slip, the torque of the four wheels of the vehicle is distributed according to the stroke of an accelerator pedal of the vehicle; if the tires of the four wheels of the vehicle are all located in a linear area but have excessive slip, or the tires are located in a saturated area but do not have excessive slip, the torque of the four wheels of the vehicle is redistributed through a DYC controller; if the tires are located in the saturation area and excessively slip, the torque of the four wheels of the vehicle is redistributed through an anti-slip contr
