External Hazard Light System for Monitoring Tire Pressure

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 tire blows. What is needed is an external hazard light system that is activated by a sudden loss of tire pressure, such as when a tire blows.

The present invention is an external hazard light system that is activated when the vehicle suddenly loses tire pressure in any of the vehicle's tires.

In Figure 1 an external hazard light system for monitoring tire pressure is shown. Tire pressure monitor 110 monitors the tire pressure of all the vehicles tires. Sudden loss of tire pressure in any of the tires causes tire pressure 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 sudden loss of tire pressure by any the tires of the vehicle as indicated by traction monitor 110 causes program logic devise 140 to activate external hazard light 170 to flash.
