A MAGNETIC PAVEMENT MARKING AND SENSOR FOR LATERAL CONTROL/GUIDANCE VEHICLES

Honeywell and 3M have worked together to develop a magnetic marking system that shows excellent potential for providing lateral location information of a vehicle on a road. The main component of the system consists of a magnetic pavement marking tape developed by 3M and a magnetoresistive by Honeywell. At 3M's transportation center in Cottage Grove, Minnesota, tests of the system showed it to have excellent sensitivity with the ability of the sensor to detect magnetic pavement marking tape up to 2 m away from the tape. These tests were conducted in a moving car with the sensor position .3 m above the road surface and the car traveling between 20 to 40 km/h using 30 m of magnetic tape. The magnetic tape has the ability to be encoded with information using methods similar to that used for magnetic audio tape. The data can be read by the sensor to provide various types of information depending upon the application. Potential applications for this system include lane deviation sensing for vehicles; snowplow lateral guidance when roads are snow covered; docking system for vehicles like trucks and buses; closed loop lateral control systems for vehicles; and, an information system for road geometric and traffic control information. Advantages of the magnetic system include high reliability, all weather performance, no power and capability with existing methods for applying pavement marking.
