Apparatus and method for controlling vehicle using vehicle communication
First Claim
1. An apparatus for controlling a subject vehicle, the apparatus comprising:
- a communication unit included in the subject vehicle and receiving, from an object vehicle, object vehicle surrounding information including lane information from a viewpoint of the object vehicle, through wireless communication;
a measurement unit measuring vehicle information of the subject vehicle;
an object vehicle detection unit detecting a location and a speed of the object vehicle, using the object vehicle surrounding information received from the object vehicle through the wireless communication and the vehicle information of the subject vehicle; and
a vehicle control unit controlling an operation of the subject vehicle using information on the location and the speed of the object vehicle,wherein the lane information from the viewpoint of the object vehicle corresponds to one or more parameters including a coefficient of an equation indicating a linear shape of a lane in an orthogonal coordinate system in which a location of the object vehicle is configured to be an original point and a heading direction of the object vehicle is configured to be an orthogonal axis.

10. An apparatus for controlling a subject vehicle, the apparatus comprising:
-
a communication unit included in the subject vehicle and receiving, from an object vehicle, object vehicle surrounding information including lane information from a viewpoint of the object vehicle, through wireless communication; a measurement unit measuring vehicle information of the subject vehicle; an object vehicle detection unit detecting a location and a speed of the object vehicle, using the object vehicle surrounding information received from the object vehicle through the wireless communication and the vehicle information of the subject vehicle; a vehicle control unit controlling an operation of the subject vehicle using information on the location and the speed of the object vehicle; and a lane information conversion unit converting first lane information from the viewpoint of the object vehicle into second lane information from a viewpoint of the subject vehicle, using the received object vehicle surrounding information of the object vehicle and the vehicle information of the subject vehicle measured by the measurement unit, wherein the lane information conversion unit comprises;
a reference point conversion unit converting a first reference point (x0, y0), which is the center of the object vehicle, into a second reference point (xr, yr), which is the center of the subject vehicle, using the relative distance information between the object vehicle and the subject vehicle, the relative location information, the heading angle information of the object vehicle, and the relative heading angle information of the object vehicle and the subject vehicle; and
a lane information calculation unit calculating the second lane information on a second coordinate system obtained by configuring the second reference point to be an original point and rotating, by a relative heading angle (θ
r), the first lane information on a first coordinate system in which the first reference point is configured to be an original point.
