In the description of the possible preferred embodiments of the invention, it is necessary to give numerous details to promote a better understanding of the invention. Even so, it will be apparent to the person skilled in the art that the invention can be implemented without these specific details. On the other hand, well-known features have not been described in detail in order to avoid unnecessarily complicating the description.

Figure 1 shows an embodiment of an anti-collision system 1 for a land vehicle 2. The anti-collision system 1 comprises a detector 21 of the presence of an obstacle 10, a processor 4 configured to estimate the type of obstacle 10 and to determine the position of the obstacle 10, and a sensor 22 of distance between the vehicle 2 and the obstacle 10. Some examples of possible obstacles 10 are other vehicles, people, rocks or trees. The presence detector 21 and the distance sensor 22 are configured to be arranged in a land vehicle 2 and the processor 4 is configured to combine the data obtained by the presence detector 21 with the measurements obtained by the distance sensor 22 with the estimate of the type of obstacle 10 and with the position of the obstacle 10. By means of this combination of data, it is possible to obtain a precise perception of the obstacle 10 sufficiently in advance to avoid the collision, estimating in advance possible future collisions of the vehicle 2 with the obstacles 10 detected .

Figure 1 shows that the processor can be part of a cloud to which the vehicle 2 is communicatively connected. This cloud can compare data of the obstacle 10 obtained by sensors of the vehicle 2 with data stored in the cloud itself or in other data stores to identify the type of obstacle 10 and the position of the obstacle 10. In other embodiments, the processor 4 is installed in the vehicle itself 2.

In some embodiments, the presence detector 21 and the distance sensor 22 are integrated into a 3D Lidar sensor. Furthermore, in some of these embodiments, the 3D Lidar sensor obtains the adequate data from the obstacle 10 so that the processor 4 estimates the type of obstacle 10 and determines the position of the obstacle 10. In this way, with a single sensor, the 3D Lidar sensor, it is possible to obtain the data necessary for the anti-collision system 1 to estimate possible future collisions with high precision.

In some embodiments, processor 4 is configured to compare the estimated rate of obstacle 10, the position of obstacle 10 and the distance between obstacle 10 and vehicle 2 with predefined values. In this way possible future collisions can be estimated and assigned a degree of importance.

In some embodiments, the anti-collision system 1 comprises an alarm configured to activate upon detecting a combination of estimated type of obstacle 10, position of obstacle 10 and distance between obstacle 10 and vehicle 2, in which the type is within a few types and the position and distance are in predefined ranges. In this way, when detecting that there is a possible future collision, the alarm can be activated. In these embodiments the alarm is preferably arranged so that its activation is perceived by an operator of the vehicle 2, for example the alarm can be arranged at a location on the vehicle 2 that is within the range of vision of an operator in the operation of the vehicle. vehicle 2.

In some embodiments the anti-collision system 1 comprises an actuator configured to act on a vehicle 2 when activated as a result of a combination of estimated type of obstacle 10, position of obstacle 10 and distance of obstacle 10, in which the type is within of predefined types and the position and distance are in predefined ranges. In this way, the vehicle 2 automatically responds to possible collisions detected by the anti-collision system 1. The vehicle 2 can respond in various ways, for example by preventing the vehicle 2 from entering a predefined geographical region or by limiting the degree of inclination of vehicle 2 for example by adjusting the brake of the vehicle. In some of these embodiments, the actuator is configured to act on the speed of the vehicle 2.

Anti-collision system 1 according to any one of the preceding claims, comprising a weight sensor, an inclinometer and / or a speed sensor.
