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 the vehicle decelerates rapidly.
In Figure 1 a sudden stop flashing brake light system 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 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 rapid deceleration of the vehicle will cause activation of flasher 150 causing brake 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.
