Sudden Stop Flashing Brake Light System

The brake lights of a vehicle serve to warn other vehicles that the vehicle is decelerating or is stopped. Conventional brake lights however, fail to indicate the rate of deceleration of a vehicle. As a result, the brake light does not indicate when a vehicle is coming to a sudden stop, which are the cause of many rear end collisions. What is needed is a brake light system that indicates when a vehicle is making a sudden stop or decelerating rapidly.

The present invention is a brake light system in which the brake light flashes when strong pressure applied to the brake pedal.

In Figure 1 a sudden stop flashing brake light system is shown. Pressure applied to the brake pedal 110 causes pressure transducer 120 (of piezo electric type for example) to generate an analog signal that is proportional to pressure applied to brake pedal 110. The analog signal from pressure transducer 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 brake light driver 160, which sends electric current to brake light 170, causing brake light 170 to flash. The algorithm contained in program logic device 140 is programmed such that strong pressure applied to brake pedal 110 will activate flasher 150 causing brake light 170 to flash. The repetition rate of flasher 150 further could be programmed to increase the stronger the pressure applied to brake pedal 110 by incorporating a flasher controller into the present system.
