Abstract: A vehicle deceleration notification system includes a deceleration sensor installed in a vehicle. The deceleration sensor measures a magnitude of vehicle deceleration. The vehicle deceleration notification system further includes a vehicle display unit installed at a rear end of the vehicle. The vehicle display unit is a linearly oriented and double mirrored display unit having a plurality of light sources. The vehicle deceleration notification system further includes a processor that obtains the magnitude of vehicle deceleration from the deceleration sensor and determines a preset deceleration range, of a plurality of preset deceleration ranges, associated with the magnitude of vehicle deceleration. The processor further selects a display mode of the vehicle display unit based on the determination of the associated preset deceleration range and actuates the selected display mode of the vehicle display unit.
