The invention relates to the field of electric vehicle control and discloses a control method of a distributed driving electric vehicle for avoiding the driving instability of electric vehicles on bisectional roads. The control method comprises that a vehicle control unit collects the speed v of the electric vehicle and the rotating speed omega of four wheels to compute out the slippage rates lambda of the four wheels; when the wheel Wi of the four wheels slips and the slippage rate lambda i of the slipping wheel Wi is larger than a slippage controlled target value lambda 0, the vehicle control unit adjusts the driving torque of the slipping wheel Wi through PID (proportion-integration-differentiation) loop control to enable the slippage rate lambda i of the slipping wheel Wi to approach the slippage controlled target value lambda 0 and to enable the rotating speed omega' of a coaxial wheel Wi' to be identical to the rotating speed omega i of the slipping wheel Wi; when the slippage rates lambda of the four wheels are not larger than the slippage controlled target value lambda 0, the vehicle control unit controls the electric vehicle through a corresponding control mode according to the driving requirements of a driver. By controlling the electric vehicle on the bisectional roads through the control method of the distributed driving electric vehicle, the driving stability of the electric vehicle can be improved.
