First Claim
Patent Images
1. A warning system for a host vehicle comprising:
- a first magneto-resistive sensor coupled to the host vehicle, said first magneto-resistive sensor sensing a first magnetic field variation in a first sensor area external to the host vehicle and generating a first sensor signal therefrom; and
a controller coupled to the host vehicle receiving said first sensor signal, said controller generating a signal for activating a vehicle system in response to said first sensor signal.

Abstract
A host vehicle system includes a blind-spot warning system providing an indication to the host vehicle a target vehicle entering a blind-spot. The system includes a vehicle bus receiving various vehicle control signals, magneto-resistive sensors receiving proximity information as a function of magnetic field variations, a smart algorithm controller analyzing bus signals and sensor signals, and various vehicle collision systems such as passive restraints, optical light guides, and audible warnings operating in response to a threat from a target vehicle.
