Study on Combined Braking of Eddy Current Retarder and the Main Brake

Aiming at the main brake force distribution by using the proportional distribution and the braking force of eddy current retarder with shift, it affected the attachment of wheels on the ground.Through the establishment of vehicle dynamics, relationship of sliding rate with braking force and the eddy current retarder braking dynamics model, the controlled method was researched by relative value as control parameters to the sliding rate and the target rate at the front wheel brake sliding.The sliding rate of the front and rear wheels was compared.Its difference value was control parameter to adjust the eddy current retarder braking force, which do compensation for the rear wheel braking force.This control strategy is carried based on the simulation analysis in Matlab/Simulink.The analysis results show that this method can make full use of road adhesion and improve the braking force and the traffic safety.
