摘要： A method and apparatus includes a processor that receives information corresponding to a first signal strength of a communication link between a remote device and a communication gateway of a vehicle. The information corresponding to the first signal strength is associated with a first antenna of a sensor and the first antenna includes a first peak main lobe magnitude oriented in a first direction. The processor also receives information corresponding to a second signal strength of the communication link. The information corresponding to the second signal strength is associated with a second antenna. The second antenna includes a second peak main lobe magnitude oriented in a second direction. The processor executes a first boundary line determination that includes determining whether the remote device is located on a first side of a boundary line based on the first signal strength and the second signal strength.
