Abstract
A boundary detection system for a vehicle includes a controller programmed to generate an alert in response to sensing a presence of a person in a first zone extending from the vehicle. The system also includes a wireless receiver configured to receive signals transmitted by a nomadic device in a second zone surrounding the vehicle. The controller is further programmed to, in response to the receiver receiving the signals, output the alert.
Claims20
A boundary detection system for a vehicle comprising:
- a controller programmed to generate an alert in response to sensing a presence of a person in a first zone extending from the vehicle;
- and
- a wireless receiver configured to receive signals transmitted by a nomadic device in a second zone surrounding the vehicle, the controller being programmed to passively monitor, via the wireless receiver, message traffic between the nomadic device and a receiver that is external to the vehicle and, responsive to detecting messages exchanged between the nomadic device and the receiver, output the alert.
A vehicle comprising:
- a boundary alert sensor configured to detect a presence of a person located in a first zone extending from the vehicle;
- a wireless receiver configured to receive signals transmitted to a receiver external to the vehicle by a nomadic device that is outside of the vehicle in a second zone surrounding the vehicle and including at least part of the first zone;
- and
- a controller programmed to passively monitor, via the wireless receiver, message traffic between the nomadic device and the receiver and, in response to the presence of the person being detected in the first zone, output an alert, and, in response to detecting messages exchanged between the nomadic device and the receiver, output the alert.
A method of detecting a person in a vicinity of a vehicle comprising:
- monitoring, by a controller, a boundary alert sensor configured to detect a presence of a person located in a first zone extending from the vehicle;
- outputting, by the controller, an alert in response to detecting the presence of the person in the first zone;
- monitoring, by the controller, for wireless signals transmitted to a receiver external to the vehicle by a nomadic device that is in a second zone surrounding the vehicle;
- and
- outputting, by the controller, the alert in response to receiving the wireless signals.
