The　existing　problems　of　current　braking　energy　regeneration　devices　are　analyzed.　A　new　energy　regeneration　scheme　is　proposed,　in　which　the　energy　in　the　process　of　vehicle　braking　is　converted　real-time　into　energy　source　of　electromechanical　braking　system,　and　it　thus　dynamically　utilizes　braking　energy　and　improves　the　efficiency　of　braking　energy　regeneration.　The　results　of　simulation　show　that　the　braking　performance　of　the　system　meets　the　requirements　of　related　national　standard.
