The invention relates to an anti-sliding control system for an electric automobile, which comprises a motor controller, as well as a motor, an accelerator pedal, an accelerator pedal sensor, a brake pedal, a brake pedal sensor, a motor current sensor and a rotary transformer that are all connected with the motor controller; accelerator pedal signals, brake pedal signals, motor current data signals, motor rotating speed data signals, rotating-transforming signals and other data of the motor controller are all collected and processed by a DSP (Digital Signal Processor) data processor; the motor is controlled by the motor controller; the signals are sent to a DSP chip data processor through all sensors, so that ramp conditions for the automobiles can be judged; svpwm (space vector pulse width modulation) duty ratio is adjusted through the controller; driving current is adjusted, so that torque of the automobile borne due to a slope is counteracted by motor driving torque; and the automobiles are prevented from sliding, so that traffic accidents are greatly reduced, and meanwhile the operation burden of starting the automobile again after a driver brakes the automobile during uphill and downhill is reduced.
