External Hazard Light System for Monitoring Deployment of Air Bag

The external hazard lights of a vehicle serve to warn other vehicles that the vehicle presents a potential hazard. Conventional external hazard lights however, must be manually activated and therefore may not provide warning of the onset of a sudden hazard, such as when an accident occurs causing the air bags to deploy. Following an accident in which the air bags have deployed the passengers of the vehicle may also be unable to activate the external hazard lights. What is needed is an external hazard light system that is indicated when a vehicle has had an accident.

The present invention is an external hazard light system that is activated when the vehicle's air bag deploys.

In Figure 1 an external hazard light system for monitoring deployment of air bag. Air bag monitor 110 monitors if air bags have deployed. Deployment of air bag causes air bag monitor 110 to generate analog signal, which it transmits to amplifier 120, which amplifies signal and transmits signal to A/D converter 130. The analog signal from amplifier 120 is converted by A/D converter 130 to a digital signal and transmitted to program logic device 140. Program logic device 140 sends signal, to flasher 150, that controls the activation of flasher 150. Flasher 150 transmits signal to external hazard light driver 160, which sends electric current to external hazard light 170, causing external hazard light 170 to flash. The algorithm contained in program logic device 140 is programmed such that deployment of the vehicle air bag as indicated by air bag monitor 110 causes program logic devise 140 to activate external hazard light 170 to flash.
