This paper provides the basis for technological intelligence for a vehicle safety project, specifically to avoid rear-end collisions between cars. The framework adopts the general model of innovation proposed by Myers and Marquis. A morphological analysis of patents based on keywords was done to find the settings already used (protected) in the patents analyzed. By listing the occupied configurations of collected patents, the unoccupied territory of configurations are suggested as technology opportunities. This analysis provides: 1) the state of art and not to reinvent the wheel, 2) avoid infringement to industrial property, and 3) discover white spaces as technological opportunities.
