US 2020/0047715 A1 · REMOTE CONTROLLER, VEHICLE FOR COMMUNICATING WITH THE SAME AND METHOD FOR CONTROLLING THE VEHICLE

Abstract

A vehicle communicating with a remote controller is provided. A vehicle includes a plurality of car antennas; a storage configured to store a distance value between the first and second key antennas; and a controller configured to select at least two of the plurality of car antennas, control transmission of signals through the selected at least two car antennas, obtain a distance value between the first and second key antennas of the remote controller based on the received signal strength and the transmission strength of the at least two car antennas when a received signal strength of at least two signals received by the first key antenna and a received signal strength value of at least two signals received by the second key antenna are received from the remote controller, and authenticate the remote controller based on the obtained distance value and the distance value stored in the storage.

Dependent claims

A remote controller comprising:

a first key antenna;
a second key antenna disposed at a predetermined distance from the first key antenna;
a detector configured to detect a strength of a signal received by the first key antenna and a strength of a signal received by the second key antenna;
and
a controller configured to:
convert information corresponding to a strength of at least two signals received by the first key antenna and a strength of at least two signals received by the second key antenna into a high frequency signal;
and
control transmission of the high frequency signal.

5 more elements

A vehicle comprising:

a plurality of car antennas configured to be spaced apart from each other;
a storage configured to store a distance value between a first key antenna and a second key antenna provided in a remote controller;
and
a controller configured to:
select at least two car antennas of the plurality of car antennas;
control transmission of signals through the at least two car antennas of the plurality of car antennas;
when a signal strength of the first key antenna and a signal strength of the second key antenna are received from the remote controller, obtain a distance value between the first key antenna and the second key antenna based on the received signal strength and a transmission strength of the at least two car antennas of the plurality of car antennas, wherein the signal strength of the first key antenna is a signal strength of at least two signals received by the first key antenna and the signal strength of the second key antenna is a signal strength of at least two signals received by the second key antenna;
and
authenticate the remote controller based on the obtained distance value and the stored distance value.

6 more elements

A method for controlling a vehicle, the method comprising:

selecting at least two car antennas of a plurality of car antennas;
controlling transmission of signals through the at least two car antennas of the plurality of car antennas;
when a signal strength of a first key antenna and a signal strength of a second key antenna are received from a remote controller, obtaining a distance value between the first key antenna and the second key antenna based on the received signal strength and a transmission strength of the at least two car antennas of the plurality of car antennas, wherein the signal strength of the first key antenna is a signal strength of at least two signals received by the first key antenna and the signal strength of the second key antenna is a signal strength of at least two signals received by the second key antenna;
identifying whether an authentication of the remote controller is successful based on the obtained distance value and a previously stored distance value;
controlling operation of at least one load provided in a vehicle when the authentication of the remote controller is successful;
and
outputting warning information when the authentication of the remote controller fails.
