PURPOSE: A system for protecting a passenger in a rear-end collision of a vehicle is provided to protect a passenger in a vehicle and to prevent a secondary collision by operating a brake depending on the impact of a collision and determining the deployment of an air bag. CONSTITUTION: A system for protecting a passenger in a rear-end collision of a vehicle comprises a vehicle collision detecting unit(100) consisting of an acceleration detecting part(110) and a distance detecting part(120) and detecting the acceleration in a rear-end collision, an engine control unit(200) receiving the acceleration signal from the collision detecting unit and outputting a brake control signal and an air bag deployment signal if the collision acceleration is over a specific value, a brake control unit(300) outputting a brake drive signal by receiving the brake control signal from the engine control unit, an air bag control unit(400) outputting an air bag deployment control signal for deploying an air bag, and a drive unit(500) consisting of a brake drive part(510), an air bag drive part(520) and an engine drive part(530).
