Method and apparatus for object recognition and warning system of a primary vehicle for nearby vehicles
First Claim
1. A vehicle to vehicle warning system comprising:
- a radio-frequency transmitter housed in a primary vehicle employing one or more oscillators to generate a radio-frequency signal;
a radio-frequency receiver housing in a secondary vehicle, said receiver configured to receive said radio-frequency signal generated by said transmitter; and
a warning device, said receiver configured to activate said warning device in the event said radio-frequency signal is detected by said receiver.

Abstract
A vehicle to vehicle warning system comprises a transmitter associated with a primary vehicle alerting one or more secondary vehicles of its proximity through a receiver. The transmitter may emit a radio frequency signal which activates radio frequency receivers in surrounding vehicles. When in appropriate proximity, the signal is configured to initiate a warning at the secondary vehicle, such as light from a light-emitting device or sound from a sound-generating device. In another form, the primary vehicle includes a passive transmitter and the secondary vehicle includes a multi-frequency resonance tag/circuit having distinct frequencies for detection and discrimination. The passive transmitter creates electromagnetic waves which are generated as it passes by the secondary vehicle housing the multi-frequency resonance tag, setting off the secondary vehicle alarm system. This warning signal can be incorporated into the vehicles existing radio/warning light system and/or as a separate device. This invention provides a low cost simple device to provide a vehicle to vehicle warning system.
