Rear collision warning system
First Claim
1. A rear collision warning system for a target vehicle and an approaching vehicle comprising:
- a first transmitter located on the approaching vehicle and directed at the target vehicle, said first transmitter generating a vehicle information signal comprising at least partially approaching vehicle related information;
a first indicator located on the target vehicle; and
a first receiver electrically coupled to said first indicator, said first receiver receiving said vehicle information signal and generating a warning signal that is indicated via said indicator to the approaching vehicle when said vehicle information signal is above a predetermined magnitude.

Abstract
A rear collision warning system (10) for a target vehicle (17) and an approaching vehicle (18) is provided. The rear collision warning system (10) includes a first transmitter (54) located on the approaching vehicle (18) and directed at the target vehicle (17). The first transmitter (54) generates a vehicle information signal. A first indicator (16) located on the target vehicle (17). A first receiver (50) electrically coupled to the first indicator (16) receives the vehicle information signal and transmits a warning signal to the approaching vehicle (18) when the vehicle information signal is above a predetermined magnitude. A method of performing the same is also provided.

-
10. A system as in claim 9 further comprising said second controller in response to said warning signal enacting a countermeasure, within the approaching vehicle, selected from the group consisting of:
- activating brakes, inhibiting fuel consumption, retracting seat belts, adjusting seat positioning, and downshifting a transmission.
-
11. A system as in claim 2 further comprising said first controller in response to said warning signal enacting a countermeasure, within the target vehicle, selected from the group consisting of:
- activating brakes, inhibiting fuel consumption, retracting seat belts, adjusting seat positioning, and downshifting a transmission.
-
12. A system as in claim 2 further comprising a wireless communication system for receiving and transmitting proximity, velocity, and direction of travel data, said wireless communication system selected from the following group consisting of:
- a Bluetooth wireless communication system, a 802.11A wireless communication system, a 802.11B wireless communication system, and a satellite wireless communication system.
-
13. A system as in claim 2 further comprising said second controller signaling said second indicator in response to relative approaching vehicle proximity, velocity, or direction of travel.
