Patent ID: 8868326

Claim:
A method for preventing collisions with an object in front of an own vehicle having at least one sensor and a brake, with the following steps: specifying an acceleration profile depending on driving variables of the own vehicle; assuming a time progression of a foreseeable acceleration of the own vehicle based on a current acceleration of the own vehicle; determining a path profile of the own vehicle from the time progression of the foreseeable acceleration; acquiring with the at least one sensor a current distance and a current relative velocity of an object in front of the own vehicle; assuming a time progression of a foreseeable acceleration of the object in front based on a current acceleration of the object in front; determining a path profile of the object in front from the time progression of the foreseeable acceleration; comparing the path profile of the own vehicle with the path profile of the object in front; and if the two path profiles intersect or the velocity of the own vehicle coincides with that of the object in front at least within a tolerance band, determining a probable collision time of the own vehicle with the object in front, comparing a time with the probable collision time established; and if the velocity of the own vehicle coincides with that of the object in front at least within a tolerance band, a residual distance of the own vehicle from the object in front and a reduction in velocity up to the time are determined, and if the velocity reduction falls below a value and the residual distance likewise falls below a value, initiating driver-independent emergency braking of the brake.
