External Hazard Light System for Monitoring Sudden Deceleration

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 a vehicle's decelerates rapidly. What is needed is an external hazard light system that indicates when a vehicle's is decelerating rapidly.

The present invention is an external hazard light system that is activated when a vehicle decelerates rapidly.

In Figure 1 an external hazard light system for monitoring sudden deceleration is shown. Speedometer 110 contains decelerometer 120 that generates an analog signal that is proportional to the rate of deceleration of the vehicle. Decelerometer 120 transmits signal to amplifier 125, which amplifies signal and transmits signal to A/D converter 130. The analog signal from amplifier 125 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 rapid deceleration of the vehicle will cause activation of flasher 150 causing external hazard light 170 to flash. The repetition rate of flasher 150 further could be programmed to increase the greater the rate of deceleration of the vehicle by incorporating a flasher controller into the present system.
