The purpose of this paper is to describe a system that provides the driver or the driving assistance system with the lateral position information of the vehicle on the lane in order to detect as early as possible run-off-road and then prevent a foreseeable crash. A magnetized tape deposited on the road in the middle of the lane generates a magnetic field which is detected by on-board sensors. Depending on the distance between the tape and the sensors, accurate positioning information can be estimated. The use of at least five sensors makes it possible to obtain a 2 mm-lateral-positioning accuracy. Magnetized tapes are relatively cheap to install and provide an accurate vehicle lateral positioning with low-cost magnetoresistance on-board sensors. In addition, a magnetization variation along the tape would allow information to be coded which could be then transmitted to the driver.
