Abstract
A vehicle key control apparatus includes a communicator receiving a response signal from a vehicle key receiving a search signal transmitted from a vehicle, wherein the response signal comprises an x-axis reception strength, a y-axis reception strength, and a z-axis reception strength; and a controller determining a position of the vehicle key on the basis of at least one among the x-axis reception strength, the y-axis reception strength, and the z-axis reception strength.
Claims19
A vehicle key control apparatus comprising:
- a communicator receiving a response signal from a vehicle key receiving a search signal transmitted from a vehicle, wherein the response signal comprises an x-axis reception strength, a y-axis reception strength, and a z-axis reception strength;
- and
- a controller determining a position of the vehicle key on the basis of at least one among the x-axis reception strength, the y-axis reception strength, and the z-axis reception strength,
- wherein the controller stores information regarding the position of the vehicle key beforehand by mapping the position to a reference x-axis reception strength, a reference y-axis reception strength, and a reference z-axis reception strength corresponding thereto.
