The system has a deceleration detector (1) to detect behavior and state parameter e.g. deceleration, of a motor vehicle. Four detectors (2-5) respectively detect anti-lock braking system (ABS) state, electronic stability control (ESP) state, fly-wheel angle, and normal/abnormal brake pedal pressure in the vehicle. Proximity/ultrasonic sensors (6) detect proximity of object or imminence of impact. A control unit (7) controls locking or unlocking of opening frames of the vehicle, when the parameter exceeds a threshold value, and calculates a warning level based on outputs of the detectors. |
