RUMBLE STRIP RESPONSIVE SYSTEM

摘要

PROBLEM TO BE SOLVED: To enable a driver to notice that a vehicle tends to depart from a road by causing noise or oscillation when tires of the vehicle run onto a rumble strip.

SOLUTION: A device to alter transfer characteristics of a road departure warning installation installed on the road to the driver of the vehicle includes a sensor to sense input from the rumble strip and an adjustable vehicle component in communication with the sensor. The adjustable vehicle component is constituted to automatically adjust an amount of the input from the rumble strip sensed by the driver. A device to estimate lateral displacement of the vehicle based on a location of the rumble strip with respect to the vehicle includes a processor constituted to receive four signals indicative of contact of the rumble strip with the respective associated four tires of the vehicle and to estimate a lateral distance that the vehicle has traveled beyond the detected rumble strip.
