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.

Autonomous vehicle emergency braking method

In a method and a device for controlling a driver assistance system of a vehicle, a process is carried out which includes the steps of emitting light of at least one wavelength onto a road surface under the vehicle, detecting the light reflected by the road surface, acquiring at least one piece of information on the nature of the road surface using the detected reflected light, transmitting the information on the nature of the road surface to the driver assistance system, and modifying at least one parameter of the driver assistance system such that the driver assistance system reacts depending on the nature of the road surface.

A method and a device for outputting a signal when there is a hazardous surface under a vehicle includes providing an optical surface sensor for determining one or more parameters of the underlying surface, a stationary-state-determining device for determining whether the vehicle is stationary or is to be brought to a standstill, and an output device that outputs a signal if the underlying surface has been determined to be hazardous on the basis of the parameter(s), and the vehicle is stationary or is to be brought to a standstill.

Device and method for outputting a signal when there is a hazardous underlying surface under a vehicle

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.
