US 12,631,763 B2 · Vehicle and node positioning method

Abstract

A vehicle includes a signal transmission part configured to transmit a signal for wireless network connection to an outside of a shaded area where a GPS signal is not received based on the vehicle having entered the shaded area. A positioning part is configured to communicate with a vehicle located outside the shaded area, to receive the signal, and to calculate a relative position of the vehicle. A first position correction part is configured to correct a current position of the vehicle based on a number of vehicles included in the other vehicle that have received the signal. A second position correction part is configured to correct the current position of the vehicle after passing through the shaded area based on location information of the vehicle in the shaded area and GPS information of the vehicle after passing through the shaded area.

Dependent claims

A vehicle comprising:

a signal transmission part configured to transmit a signal for wireless network connection to an outside of a shaded area where a global positioning system (GPS) signal is not received based on the vehicle having entered the shaded area;
a positioning part configured to communicate with at least one other vehicle located outside the shaded area, to receive the signal, and to calculate a relative position of the vehicle;
a first position correction part configured to correct a current position of the vehicle based on a number of vehicles included in the at least one other vehicle that have received the signal;
and
a second position correction part configured to correct the current position of the vehicle after passing through the shaded area based on location information of the vehicle in the shaded area and GPS information of the vehicle after passing through the shaded area.

A node positioning method, the method comprising:

transmitting, by a mobile node having entered a shaded area where a GPS signal is not received, a signal for wireless network connection to an area outside the shaded area;
performing communication, among neighboring nodes located outside the shaded area and receiving the signal and among the neighboring nodes and the mobile node, to establish the wireless network connection among the neighboring nodes and the mobile node;
calculating a relative position of the mobile node;
calculating a current position of the mobile node based on a number of neighboring nodes that have received the signal;
and
after passing through the shaded area, correcting, by the mobile node, the current position of the mobile node after passing through the shaded area based on location information of the mobile node in the shaded area and GPS information of the mobile node after passing through the shaded area.
