Abstract
A collision warning system warns vehicles traveling behind a vehicle when it initiates deceleration. A receiver on trailing vehicles receives the signal. A transmitter then transmits a signal in response to either the acceleration sensor or the receiver. A brake warning device is also automatically actuated upon reception of the signal, and the signal is retransmitted to the rear of a trailing vehicle. A warning provided in this manner allows operators several vehicles in back of the lead vehicle to be simultaneously notified that the lead vehicle is decelerating, independently of whether the intervening vehicles have manually applied their brakes.
