1. A method for operating a brake assist device for a vehicle, the method comprising:
- classifying a road on which the vehicle is being driven;
determining an absence of a driver action; and
performing an assist function based on a distance of the vehicle from an object in front of the vehicle, the assist function including at least one of generating a warning indication and initiating an automatic braking process, wherein the assist function is only executed if at least one trigger release condition based on the classification is fulfilled;
wherein the classifying of the road involves a division into at least two classes of roads, including a first class as a highway-like road type and a second class as a non-highway-like road type;
wherein a first triggering release condition of the at least one triggering release condition is assigned to the first class and a second triggering release condition of the at least one triggering release condition is assigned to the second class, and the first triggering release condition sets a lower threshold for execution of the assist function for the highway-like road type than the second triggering condition for the non-highway-like road type;
wherein the assist function is performed in a plurality of escalation stages and includes at least the generation of a warning indication followed by the initiation of an automatic braking process; and
wherein a respective escalation stage (E1 to E3) of the assist function is selected or triggered on the basis of the classification of the road on which the vehicle is being driven.

Abstract
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.

6. A brake assist device for a vehicle, comprising:
-
a detection unit configured to detect a distance of the vehicle from an object in front of the vehicle; a detection unit configured to detect driver actions of a driver of the vehicle; a control unit configured to execute an assist function based on the detected distance and the detected driver actions, wherein the assist function includes at least generation of a warning indication or the initiation of an automatic braking process; and an environment monitoring device configured to capture environment data relating to a road on which the vehicle is being driven, wherein the control unit includes a processing unit coupled with the environment monitoring device, by means of which the road on which the vehicle is being driven can be classified with the aid of the captured environment data, and wherein the control unit is configured to execute the assist function on the basis of the classification of the road on which the vehicle is being driven; wherein the classifying of the road involves a division into at least two classes of roads, including a first class as a highway-like road type and a second class as a non-highway-like road type; wherein a first triggering release condition of the at least one triggering release condition is assigned to the first class and a second triggering release condition of the at least one triggering release condition is assigned to the second class, and the first triggering release condition sets a lower threshold for execution of the assist function for the highway-like road type than the second triggering condition for the non-highway-like road type; wherein the assist function is performed in a plurality of escalation stages and includes at least the generation of a warning indication followed by the initiation of an automatic braking process; and wherein a respective escalation stage (E1 to E3) of the assist function is selected or triggered on the basis of the classification of the road on which the vehicle is being driven.
