A method for operating a brake assist device for a vehicle and a brake assist system for carrying out the method involve effecting an assist function, in the absence of driver action, in a plurality of escalation stages on the basis of a distance of the vehicle from an object located in front of the vehicle. A warning indication is generated as an assist function and/or a braking process of the vehicle is initiated automatically. A road on which the vehicle is being driven is classified, and the execution of the assist function is permitted or prevented on the basis of the classification.

A method and apparatus for triggering automatic emergency braking in a vehicle, such as a truck, provides an assistance function for avoiding or mitigating the effects of a rear end collision with a vehicle traveling ahead. A driver warning is triggered if a predefined warning condition requires that an automatic emergency braking process is triggered, but only after the expiration of a predefined warning time period, in order to avoid the vehicle having a rear end collision with the vehicle traveling ahead.

In a method for determining the state of a road during driving of a motor vehicle, the sound which is generated when a vehicle tire rolls on an underlying surface is sensed. A frequency signal is determined by means of a sound level signal which describes the sound, and is divided into at least two sub-zones by means of at least one limiting frequency. The sub-zones are each assigned to an associated frequency band, and an intensity value is determined for each of at least two frequency bands from the assigned sub-zone of the frequency signal. The intensity value is characteristic of the sound intensity which is present in a frequency band. An intensity ratio is formed from two intensity values by dividing the first intensity value of the first frequency band by the second intensity value of the second frequency band, and is used to determine the state of a road.

A steering system for a motor vehicle, which allows steer-by-wire operation, a hand-torque actuator being connected in the steer-by-wire mode to a steering handle, e.g. a steering wheel, to simulate a steering resistance or a restoring torque. In order to be able to ensure adequate operating safety for the vehicle if the hand-torque actuator fails, even if the steering system is operated on a steer-by-wire basis, damping means are provided, which damp adjusting movements of the steering handle by the driver in the steer-by-wire mode if the hand-torque actuator fails.
