Abstract
A vehicle wireless transmitter system includes a collision avoidance sensor in a wireless transmitter. The wireless transmitter generates a wireless signal, such as a garage door opener signal, based upon information from the collision avoidance sensor. The wireless transmitter generates a garage door opener signal when the collision avoidance sensor determines that the vehicle is within a predetermined distance of the garage. The wireless transmitter generates a garage door opener signal when the collision avoidance sensor determines that the vehicle is in the garage, the engine is no longer running and no motion is detected around the vehicle for a predetermined period of time.
