Abstract

Normal vehicles, especially passenger cars, are like isolated bubbles: their windows closed, their interior airconditioned and their radio playing. Under these conditions, it is rather difficult to grab the attention of a unknown driver for a purpose other than driving, such as asking for directions, bringing a flat tire or an open door to the attention of an otherwise oblivious driver, donating information about the length of the jam the driver is in, and the like. Although one may open one's window and shout, this methos is rather ineffective, and almost inapplicable to vehicles moving in opposit lanes. Use of mobile phones would be appropriate in this case, but normally one is not aware of the phone number of another chance driver. This disclosure describes a simple way for two drivers that just happen to be near each other to exchange phone numbers quickly enough to make the transfer messages of the type listed above practical. The problem may not warrant developing special technology for, but fortunately, all the required capabilities are commonly available, and only need harnessing to make this possible.

Normal vehicles, especially passenger cars, are like isolated bubbles: their windows closed, their interiors airconditioned and their radios playing. Under these conditions, it is rather difficult to grab the attention of a unknown driver for a purpose other than driving, such as asking for directions, bringing a flat tire or an open door to the attention of an otherwise oblivious driver, donating information about the length of the jam the driver is in, and the like.

Although one may open one's

Use of mobile phones would be appropriate in this case, but normally one is not aware of the phone number of another chance driver. This disclosure describes a simple way for two drivers who just happen to be near each other to exchange phone numbers quickly enough to make practical the transfer messages of the type listed above. The problem may not warrant developing special technology, but fortunately, all the required capabilities are commonly available and only need harnessing to make this possible.

    In principle, the system provides a driver with controls to select the vehicle at a particular orientation to his own, say front, back, left and right (see Figure 1) as the target for communication. Four buttons on the dashboard could serve as possible embodiment. Once selected, the initiating side determines its own location using a GPS type device and, based on its orientation to the called vehicle, computes an approximate position for the latter vehicle as well. It then broadcasts a message using a walkie-talkie type device, notifying all receivers in the area of its desire to communicate with a vehicle at that approximate location.

All receivers process the

message, but only the vehicle whose position matches that in the message should respond. The response contains an address, such as a mobile phone number, for continuing the communication using an established communication means. For example, the mobile phone of the selected driver will ring, allowing the two drivers to talk, exchange SMSs or anything else.
