In order to know the performance characteristic of eddy current retarder, a comprehensive evaluation method of performance characteristic of eddy current retarder was studied. Based on the introduction of structure and working principle of the eddy current retarder, the performance characteristic and requirement of eddy current retarder were analyzed. Five performance characteristic evaluation parameters （the average braking moment, thermal decline coefficient, braking efficiency, braking efficiency per unit mass, product price） which were regarded as performance evaluation indexes of eddy current retarder used in vehicle were put forward. A weighted comprehensive evaluation to the five parameters of eddy current retarder was performed by means of the value analysis method. The examples cited in this paper prove that the method is intuitionally comparable in evaluating the performance of different retarders. and the results obtained are valid and authentic.
