Resumen
[0001] Safety system for vehicles, applicable to transmitting information from a vehicle confronted with emergency conditions to a control centre, in such a way that the latter is able to locate the position of the said vehicle and to take the appropriate decisions. The system makes use of a device which sends/receives digital messages to or from a control centre via the GSM communications system. The said messages contain information relating to the position of the vehicle and are generated in response to a message coming from the control centre or by activation of alarm means which are provided in the vehicle. The control centre thus has available the relevant information on the vehicles and on the geographical area covered by the system and can process it jointly with the information transmitted to the vehicle and/or received therefrom. [0002] The interchange of information between the control centre and the vehicle or vehicles takes place in the form of short data messages through the short message service of the GSM network, with the intervention of a service centre of the said network for storing and distributing the said short messages.
