Abstract:
A vehicle deceleration communication system comprising:a deceleration detecting sensor mounted on a decelerating device for detecting deceleration action performed by a driver in traveling so as to send out a deceleration signal; a deceleration signal emission displaying device activated by said deceleration signal from said deceleration detecting sensor, said deceleration signal emission displaying device comprising a deceleration signal emitter mounted at a rear end of a car and a deceleration display to alert a trailing car driver to deceleration of the car; and a deceleration signal reception displaying device comprising a deceleration signal receiver mounted at a front end of the car and a received signal display which will flash and send out warning sounds to alert the trailing driver to the deceleration of the front car; wherein said deceleration detecting sensor is connected and mounted adjacent to an acceleration pedal or a combustion system, so that when the driver releases said acceleration pedal to slow down said car, said deceleration detecting sensor will be activated to send out a signal; said deceleration detecting sensor is mounted on a speedometer of said car and controlled by speed of said speedometer to send out deceleration signal; said deceleration detecting sensor will not work until said car travels at a speed above a predetermined value and can be manually switched on or off as required; said deceleration signal emitter is wholly or partially mounted on a rear end of said car for emitting signal from said rear end of said car, and said deceleration display is mounted on an outer or inner side of a rear window of said car to enable it to be easily seen by a trailing car driver; horizontal range of signal emitted by said deceleration signal emitter is larger than the width of a car, and vertical range and strength of said signal is adjustable as required; said deceleration display includes one or more displays with flashing or scrolling messages wherein frequency of the flashing and scrolling messages is proportional to decrease of car speed; said deceleration signal reception displaying device is wholly or partially installed on a front end of said car and installed at any place within said car which is convenient for the driver to perceive by vision or hearing; said deceleration signal receiver has a horizontal receiving range which is larger than the width of a car, and a vertical range and capability of receiving signal is adjustable as desired.
