Merge Sensor Control System
First Claim
1. A proximity sensor control system for selectively and automatically actuating a proximity sensor to detect and warn of a hazardous lateral proximity between a land vehicle in forward motion and an external obstacle so as to improve the safety of lateral merges, wherein the system is adapted for use with a land vehicle equipped with a directional signal light on a lateral side of the land vehicle, a current source, and a directional signal selector switch operable to selectively direct the current source to power the directional signal light, wherein the sensor control system comprises:
- a selectively actuatable proximity sensor capable of sensing an external obstacle and sending a responsive signal, in use mountable to said land vehicle in a laterally disposed position suitable for sensing external obstacles on a lateral side of the land vehicle, relative to the direction of forward motion;
a slave switching means for actuating said proximity sensor, connectable in communication with said directional signal selector switch to actuate said proximity sensor in response to the directional signal selector switch actuating said directional signal light; and
a warning means for communicating with said proximity sensor to receive an indication of said responsive signal and issuing a warning that the sensor has sensed an external obstacle.

Abstract
A land vehicle is equipped with a warning system for improving the safety of lateral merges. A directional signal selector switch actuates the directional signal lights on a selected side of the vehicle. Proximity sensors are mounted on the sides of the vehicle to sense external obstacles. A slave switch works in cooperation with a directional signal selector switch to actuate the proximity sensors on the same side as the actuated directional signal lights. A warning device communicates with the actuated proximity sensors to receive an indication when sensor has sensed an external obstacle and to issue a warning.
