ABSTRACT:
In the event of an accident encountered by a vehicle, an emergency signal is automatically transmitted for asking a rescue. An acceleration of the vehicle in the inclination of the vehicle and the presence or absence of water within the vehicle are detected, and an emergency signal is transmitted whenever one of these items indicates the occurrence of an abnormality. A plurality of antennae are disposed at mutually different locations on the vehicle, and are selectively used for transmission of an emergency signal. The antenna selected is periodically and sequentially changed.
