Abstract: A vehicle parking method in a smart parking system is provided. The vehicle parking method includes measuring, by parked vehicles, inter-vehicle distance values by using sensors embedded therein, receiving, by a parking target vehicle, the inter-vehicle distance values from the parked vehicles by using vehicle-to-vehicle (V2V) communication, selecting one distance value from among the inter-vehicle distance values, and determining the selected distance value as a parking space, transmitting, by the parking target vehicle, a movement request message to two parked vehicles configuring the parking space by using the V2V communication, moving, by the two parked vehicles, based on the movement request message and extending the parking space to an available parking space, and performing, by the parking target vehicle, an automatic parking process for parking in the available parking space.

Abstract: Disclosed is a seamless complex positioning method using heterogeneous positioning techniques, the method including: performing, by a positioning control apparatus, satellite signal-based positioning in an area where a satellite signal is received; determining, by the apparatus, whether a first position of a mobile terminal determined using satellite signal-based positioning is close to a shaded area; determining, by the apparatus, a non-satellite signal-based positioning scheme supported in the shaded area when the first position is close to the shaded area; determining, by the apparatus, a second position of the mobile terminal while performing satellite signal-based positioning and positioning according to the non-satellite signal-based positioning scheme simultaneously when the first position is close to the shaded area; and stopping, by the apparatus, satellite signal-based positioning and performing only positioning according to the non-satellite signal-based positioning scheme when the second position is inside the shaded area.
