ABSTRACT:
A method for detecting an object in a motor vehicle environment uses a detection means which scans the environment at predetermined angular increments φi+−φi (i=1,2, . . ., N). When sensing a reflection signal of the object at an angle φi, the angular increments are refined in the angular range between the adjacent angles φi−1 and φi+1 as a function of signal propagation times ti−1, ti and ti+1 of the reflection signals sensed at the angles φi−1, φi and φi+1.
