【Abstract】Electromechanical Braking （EMB）technology is driving a generational shift from hydraulic to brakeby-wire systems.Targetingautonomous driving requirements，this study employs theoretical comparison and empirical analysis to reveal EMB’s triple breakthroughs over hydraulic systems.Structural Reconstruction： Electromechanical direct-drive architecture eliminateshydraulicpipelines，reducingcomponentsby 40% and mass by 24.1% .Performance Leap： Response time ≤ 100ms 30% faster）， control precision ±0.01MPa 0 85% higher），reducing collision kinetic energy by 62% in AEB scenarios.Energy Eficiency Innovation： Enhancing endurance by optimizing drag torque.Localization practices confirm feasibility： xxx company curbs torque attenuation at -40C 6% ）. The new regulation GB 21670—2025， to beimplementedon January lst，2O26，will accelerate industrial substitution.Future eforts must resolveredundancy costschallengestoward integrated "brake-drive-steer" smart actuators.
