The invention discloses an eddy current retarder controller. The controller comprises a single chip microcomputer, a signal input module, an indicating lamp, a CAN communication interface, a drive circuit and a current sampling circuit, wherein the signal input module, the indicating lamp, the CAN communication interface, the drive circuit and the current sampling circuit are connected to the single chip microcomputer, the IGBT module of the drive circuit is connected to the single chip microcomputer through a gate circuit U3, the current sampling circuit comprises a sampling resistor R3, a retarder coil group L, an over-current protection circuit U4, a sampling signal conditioning circuit U5 and the like. The eddy current retarder controller is simple in structure, reliable in performance, judges the vehicle load situation, brake demand amount and the like of a vehicle at present by acquiring engine rotation speed, throttle opening degree, vehicle speed, temperature and other information, automatically adjusts output duty ratio of the IGBT module, reduces current of a retarder coil, accordingly automatically decreases output braking force, achieves automatic load adjustment control and ensures running safety.
