Abstract：To meet the high-performance braking requirements of light commercialvehicles，anoptimization design method for the structural parametersofthe brake-by-wire （BBW）system basedonmulti-objective optimization was proposed.This method established the basic configurationof the wire-controlld motion system，formulated optimizationobjective functionsand constraint conditions for braking force，transmission eficiency，and theend motionspeedof theactuator.The weightsofeach objective function were calculated using the fuzzyanalytic hierarchy process，and a multi-objective comprehensive optimization function was constructed through linear weighting.Based on this function，the particle swarmoptimizationalgorithm was employed to solve for the optimal valuesof the multi-objective function，therebydetermining the structural optimization parameters of the wire-controlled motion system.This ensured that the overall performance of the system reached its optimal state.The results indicate that following the parameter optimization design，the braking forceof the BBWsystemincreasesby 8.8% ，theend movement speed of theactuator improves by 12.5% ，and the transmission efficiency rises by 5.1% .The proposed optimization method for the comprehensive performance index effectively enhances the braking capacityand operational efficiency of the BBWsystem.
