Automobile Deceleration Indication (ADI) System

In many circumstances, an illuminated brake light suffices as an indication of some level of deceleration. However, in some situations involving heavy deceleration, such as a collision, the vehicle's brake lamps are not illuminated because the driver fails to depress the brake pedal. Further more, not all drivers are able to quickly determine the rate at which a car is decelerating when only aided by an illuminated brake light. The rate of deceleration of other motor vehicles becomes increasingly important information when unfavourable weather brings slippery road conditions. This scenario underlines the need for a visual deceleration indicator for motor vehicles.The implementation of our solution requires a deceleration detection unit, a processing unit and a deceleration indicator. The first stage detects the rate of the deceleration of vehicle. This information is then processed to determine what further action should be taken. If the rate of deceleration exceeds a certain predetermined threshold, the deceleration indicator would be engaged to indicate the vehicle's rate of deceleration to drivers behind the car. The current indication system under consideration for development involves a set of lights that could be illuminated in accordance with the vehicle's deceleration. The number of lights illuminated would increase with the deceleration of the vehicle
