Anti-collision system and method for ground vehicles

An anti-collision system for ground vehicles, comprising:

• a first transceiver device, associated with an obstacle, configured to generate and transmit one or more wireless signals at pre-established time intervals, the first wireless signal carrying an obstacle identification code;
• a second transceiver device, associated with a ground vehicle, configured to transmit one or more wireless signals and to receive said first wireless signal which carries the obstacle identification code;
• said first transceiver device being configured to receive said signals transmitted by the second transceiver device associated with the ground vehicle;
• a processing unit installed in the ground vehicle and configured to process collision data, comprising:
• a first calculation module configured to determine the trajectory of the ground vehicle and of the obstacle as a function of said wireless signals and said wireless signals;
• a second calculation module configured to determine, on the basis of said trajectory, the probability of collision between the ground vehicle and the obstacle;
• an alerting module configured to generate and send a signal of probability of collision between the ground vehicle and the obstacle as a function of a high probability of collision between said ground vehicle and the obstacle,
• wherein the processing unit calculates a relative distance from the ground vehicle to the obstacle based on signal power of a signal received from the obstacle;
• a tag associated with the obstacle, wherein the tag is configured to engage in different types of information exchange with different vehicles:
• the first type is based on an initial request message containing a unique destination ID, wherein only a vehicle holding that ID can respond;
• and the second type is based on an initial request message directed to vehicles within a predefined range, wherein any vehicle within that range can respond.
