The invention discloses an eddy current retarder control system based on a voltage reduction constant current source. The eddy current retarder control system based on the voltage reduction constant current source comprises an eddy current retarder and is characterized by also comprising a singlechip, a voltage reduction constant current power supply, a braking pedal, a gear switch, a pulse signal acquisition unit, a switching value signal processing unit, a CAN bus data transceiving unit and a braking car lamp driving unit which are respectively connected with the singlechip, a car main control unit and a trip computer which are respectively connected with the CAN bus data transceiving unit and an eddy current retarder driving unit connected with the switching value signal processing unit; and the eddy current retarder is also connected with the pulse signal acquisition unit and the eddy current retarder driving unit. The eddy current retarder control system based on the voltage reduction constant current source has the advantages that sharing of a vehicle signal is realized, wire harnesses on a vehicle are reduced, and the reliability of the eddy current retarder control system can be improved; meanwhile, the eddy current retarder control system based on the voltage reduction constant current source has constant working current, so that the eddy current retarder can be stably controlled, and the braking performance of the eddy current retarder is improved.
