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.

A wireless transmitter system for a vehicle that optionally travels along a route, there existing at a location of the route a control system for selectively permitting and restricting passage of the vehicle traveling along the route past the location on the route, the control system normally restricting the vehicle from proceeding past the location, said wireless transmitter system comprising:
- a transmitter for selectively transmitting a wireless signal, the control system being responsive to receipt of the wireless signal to permit passage of the vehicle past the location;
- and
- a sensor for determining a position of said transmitter relative to the location,
- wherein said transmitter automatically transmits the wireless signal to the control system based upon the position determined by said sensor.
A wireless transmission method for a vehicle that optionally travels along a route, there existing at a location of the route a control system for selectively permits and restricts passage of the vehicle traveling along the route past a location on the route, the control system normally restricting the vehicle from proceeding past the location, said method comprising the steps of:
- selectively transmitting a wireless signal from a transmitter, the control system being responsive to receipt of the wireless signal to permit passage of the vehicle past the location;
- and
- determining a position of said transmitter relative to the location,
- wherein said transmitting step automatically transmits the wireless signal to the control system based upon the position determined in said determining step.
