Abstract:

Expressways facilitate high-speed cruising of vehicles / cars at speeds in excess of 100 kmph .However during nights when the visibility is not up to the mark, the driver is unable to make out if the vehicle ahead is slowing down. Since the vehicles are at high speed , the fraction of time available for the driver to act and brake is small .Such a scenario may end up with collision & resulting in piling up of vehicles one after the other . Therefore to alert the driver an intermediate position to braking is proposed. In the proposed design, the deceleration in excess of predetermined value is sensed by infrared sensor. The sensor will sense either wheel speed or the propeller shaft speed in ideal conditions .This signal is sent to Arduino, UNO microcontroller to which LED (Brake light) is interfaced .When the deceleration is more than predetermined value, the LED will blink for four times . When the vehicle is braked & the wheel tends to attain zero speed the LED will glow as per the existing brake light designs .The proposed arrangement of blinking & glow is to be done in the brake light module itself , thus avoiding confusion . In the prototype we have used motor with a disc mounted on its shaft. The disc speed is sensed by infrared sensor which is interfaced with Arduino UNO microcontroller .Thus the idea is demonstrated with the help of prototype.
