ABSTRACT:
An automotive safety system that will automatically activate hazard warning lights under circumstances of hard braking or sudden stoppage. The system incorporates an accelerometer which measures the longitudinal acceleration of the vehicle and a microcontroller which processes the acceleration readings. When a series of deceleration values in excess of a predetermined threshold is detected, the microcontroller transmits an activation signal and the hazard warning lights are activated to warn other motorists. The hazard lights, when activated, remain active until they are either manually reset by the vehicle operator or automatically reset by the microcontroller when it detects a series of positive acceleration values consistent with normal vehicle operation. The hazard warning lights of this system are activated independently of the brake lights such that, in an accident situation, the hazard lights will activate even if the vehicle operator has not pressed the brake pedal.
