Method of
determining
road lane
This technology uses carrier-based differential GPS
information having accuracy of recognizing a road
lane and a precise electronic map in which road
lanes can be identified. Also, a steering model of a
vehicle is used to further exactly determine a road
lane on which a current vehicle is being driven.

Distinctiveness
• Vector error information in a heading direction of a vehicle on a lane and that in a direction
perpendicular to the heading direction of the vehicle are received to be used for correction of a
position.
• Position information of the vehicle being currently driven is analyzed to determine a current
position, and position error information is reflected.
Technical effects
• Due to an external environment such as a satellite state or weather, an error may be present in
vehicle position information based on the satellite navigation information. It is possible to further
precisely verify a current position of the vehicle by correcting position information being received
at the vehicle based on position error information measured at the fixed body.
• This technology has great significance in view that in the field to which this technology pertains,
limitations of vehicle position recognition using a general GPS satellite navigation code are
overcome, and further enhanced position precision can be accomplished.

• From a long-term point of view, the connected
car market is in an intermediate step between
development of driverless driving and current
vehicle industries. Also, the connected car market
that exhibited 7 millions of cars in size globally as
of 2014 is expected to reach 69 million cars in 2020
and to rapidly grow.
• Most of the connected cars in North America are
purchased in the U.S., and about 20 million cars (95%)
out of new 21 million cars to be produced in 2020 are
expected to be mounted with the automatic Internet
connection option.
