Abstract
A system for guiding a driver of a vehicle is disclosed. The system comprises a light sensor configured to detect light; and a processor configured to determine a position of vehicle on a roadway based on a characteristic of the detected light.
Claims7
A system for guiding a driver of a vehicle travelling along a travel lane of a roadway, the system comprising:
- a sensor configured to receive and detect signals originated and transmitted from a guiding device located remote from the vehicle, the guiding device comprising a plurality of emitters, wherein each emitter simultaneously providing a signal, wherein with each emitter signal having one or more characteristics designating a particular direction from the guiding device that is different than each other of the plurality of emitter signals;
- and
- a processor configured to determine a position of the vehicle relative to a side edge of the travel lane, based on one or more of said characteristics received from the detected signal,
- wherein the one more characteristics is one or more of a modulation code and a polarization angle.

A method for guiding a driver of a vehicle travelling along a travel lane of a roadway, the method comprising:
- receiving signals at a sensor configured to receive and detect signals originated and transmitted from a guiding device located remote from the vehicle, the guiding device comprising a plurality of emitters, with each emitter signal having one or more characteristics designating a particular direction from the system that is different than each other of the plurality of emitter signals;
- wherein each emitter simultaneously providing a signal and
- determining one or more characteristics of the received signals;
- and
- based on the determined one or more of said characteristics of the signal, determining a position of the vehicle relative to a side edge of the travel lane.
- wherein the one or more characteristics is one or more of a modulation code and a polarization angle.
