Abstract
A method and a device for sensing and analyzing an imminent collision of a motor vehicle with an obstacle. Using an FMCW radar method, obstacles are detected in the form of a spectral line. Via a proper filtering, time profiles of amplitude values of the spectral lines are produced and recorded. By comparing one actively recorded time profile to stored characteristic profiles, a lateral offset y between the motor vehicle and the obstacle is determined. Alternatively or in combination, the lateral offset can also be determined on the basis of characteristic profiles of relative velocity values.
