Abstract: A method for autonomous emergency braking in a road vehicle to avoid or reduce the severity of an accident includes measuring the speed of the vehicle during autonomous emergency braking and additionally determining vehicle speed independent of the wheel rotational speeds of the vehicle. In this way, the vehicle speed can be determined sufficiently accurately even in the cases in which, as a result of sharp autonomous braking, the vehicle speed is higher than the wheel rotational speeds.

The motion sensor comprises a light source unit (12) for emitting light of at least one wavelength onto the subsurface (1), at least one detector (22) for detecting light reflected by the subsurface, and an evaluation device (50) for detecting a change in the intensity of the detected reflected light over time.

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.

Abstract: The invention proposes a method for correctly carrying out autonomous emergency braking in a road vehicle (1) in order to reduce the severity of an accident, the speed of the vehicle being determined during the autonomous emergency braking. According to the method, a determination of speed which is independent of the wheel rotational speeds of the vehicle is additionally used. By this means, the vehicle speed can be determined sufficiently accurately even in the cases in which, as a result of sharp autonomous braking, the vehicle speed is higher than the wheel rotational speeds.
