Abstract
A driver assistance system includes a speed detector, a preceding vehicle detector having at least one video camera and at least one distance sensor for detecting the distance from a preceding vehicle, a device for determining the speed of the preceding vehicle, and an electronic control unit equipped to trigger an autonomous deceleration of the vehicle with the presence of predetermined brake trigger driving data and to terminate the autonomous deceleration with the presence of predetermined brake abortion driving data. The control unit effects: redundant detection of preceding vehicle driving data, and non-redundant detection of preceding vehicle driving data if a redundant detection is not possible. The non-redundantly detected preceding vehicle driving data is compared to preceding vehicle driving data redundantly detected within a predetermined time, and the non-redundantly detected data is used to control the autonomous deceleration if it corresponds to the redundantly detected data.
