The invention discloses an anti-skid control method and system for driving of an intelligent electric vehicle. The control method comprises the steps that data are collected and processed; calculating the required amount in the driving anti-skid process; aSR flag bit detection and processing; calculating a basic moment; the ASR controller calculates the torque of each motor in a vehicle slipping state; distributing a torque transfer vector in a vehicle slipping state, and calculating the output torque of each motor; and controlling the vehicle to move according to the output torque of each motor. The control system comprises a signal acquisition module, a central control module and an execution mechanism module. Based on the intelligent electric vehicle with a distributed architecture, through fusion processing of multiple information sources and according to judgment of the wheel state, dynamic torque transfer is achieved, the driving requirement of a driver can be better responded, and the control effect of driving anti-skid control is further improved.
