According to the data given by the sensors (positions, speed, weights and inertia, wind speed and direction…) the system calculates a dynamic and temporal safety area called “dynamic and temporal safety cocoon”. The onboard radar allows to identify its risk environment, i.e. the whole neighbouring safety cocoons formed by the other mobiles and motionless obstacles.

The system then estimates the collision risk and takes all the corrective measures via its automatic pilot in case of needs to avoid any intersection between the mobile’s cocoon and the neighbooring cocoons.

Then the calculation of risk module estimates the collision risk of the mobile and sends it to the decision expert system which can automaticaly starts a collision avoidance process.
