Abstract
A passive garage door opener system includes a sensor for determining the position of the vehicle relative to the receiver. When the vehicle is within a predetermined area near the receiver, the transmitter sends the signal to open the garage door. Other conditions of the vehicle, such as speed and heading, may also be monitored to determine when and whether to send the signal.
