PURPOSE: A car bump sensor system is provided to sense the deviation of a lane by using the lane deviation sensing sensor and controller of an LDWS(Lane Departure Warning System), thereby guaranteeing the safety of a passenger by operating a bump protection device more quickly. CONSTITUTION: A car bump sensor system comprises a bump sensor(200), a lane sensor(300), and a controller(100). The bump sensor measures the degree of impact. The lane sensor recognizes the lane of a road. In case that the degree of impact exceeds a bump reference value, the controller operates a bump protection device. If a car deviates from the lane, the controller lowers the bump reference value to reduce the operation timing of the bump protection device.
