Abstract

Provided is an autonomous vehicle assistance device and method that may precisely determine a position of a vehicle based on input position error information. The autonomous vehicle assistance device includes a communicator configured to receive satellite navigation information, correction information transmitted from a base station, and position error information transmitted from a fixed body, and a vehicle position determiner configured to calculate first position information corresponding to the received satellite navigation information and correction information and to calculate a current position of a vehicle by correcting the first position information based on the position error information.

Claims

1. An autonomous vehicle assistance device to be provided to a fixed body, comprising:

a communicator configured to receive satellite navigation information and correction information from a base station; and

an error calculator configured to acquire first position information corresponding to the satellite navigation information and the correction information, to calculate a difference value between the first position information and second position information stored in the autonomous vehicle assistance device, and to acquire a position error vector.

2. The autonomous vehicle assistance device of claim 1, wherein the communicator is further configured to receive a request for the position error vector from a vehicle within a preset radius and to transmit the position error vector to the vehicle.

3. The autonomous vehicle assistance device of claim 1, wherein the communicator is further configured to transmit a unique identification signal of the autonomous vehicle assistance device corresponding to the second position information.

4. The autonomous vehicle assistance device of claim 1, wherein the error calculator is further configured to acquire the position error vector in each of a heading direction of the vehicle on a lane around a position at which the fixed body is installed and a direction perpendicular to the heading direction, in correspondence to the lane.
