The invention discloses an intelligent control drive and the control method for an eddy current retarder. Switching signals includes switch signals which has 7 manual shifts: neutral, 1 block, 2 block, 3 block, 4 block, 5 block, constant rate, ABS switch signals, vehicle speed switch signals and acceleration pedal switch signals; analog signals includes: braking pedal analog signals and rotor temperature analog signals. A microprocessor gathers signals at real time, counts braking moment whose size is needed by the braking and outputs PWM signals of duty rate corresponding to the braking moment, simultaneously, instructs circuits, drive circuits of the microprocessor and brake light drive circuits, and speeds up pedal redundant wrong direction output circuit to send out corresponding control orders; the invention uses a discrete structure, causes a electrically controlled unit and a power module to be separated respectively, and has the advantages of saving space, easy installation and that coils are not easily damaged; rotor disk is not deformed by uniform stress; the life of the eddy current retarder is improved.
