    Abstract
  • When vehicle was on the roads with different road adhesion coefficients, the influence of eddy current retarder at different gears on vehicle braking performance was investigated.The ideal braking force distribution curves of front and rear wheels and front and rear arresters were studied, and their matching relations were analyzed.The concept of braking force utilization was introduced to reflect braking performance, and the braking force utilization algorithms were deduced based on different matching relations.When the retarder of a light passenger car was at different gears, the relation between braking force utilization and road adhesion coefficient was analyzed based on numerical analysis method.Study result indicates that when retarder works, braking force utilization first increases and then decreases with the increase of road adhesion coefficient.Braking force utilization is above 90% when retarder is at low gears, and road adhesion coefficient is between 0.06 and 0.81, the braking force utilization has a downward trend with the increase of retarder gear, so retarder should not be working at the highest gear for long time.
