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.

The opening of vehicle doors often leads to collisions with stationary obstacles that are not visible to the occupants or with moving obstacles that approach the vehicle without being noticed. Thus to avoid collisions when vehicle doors are opened, the aim of the invention is to take any modifications to the environmental situation of the vehicle as a result of a movement of the vehicle and the detected objects into consideration. This allows a collision of the vehicle doors with the objects to be reliably avoided. To achieve this, in a first step the probable trajectory of a vehicle is determined. In an additional step, the objects in the vicinity of the vehicle are detected and probable trajectories of said detected objects are determined. Respective probability ranges are then defined both for the vehicle and the pivoting zone of the vehicle doors and for the detected objects. The probability ranges of the pivoting zones of the vehicle doors are respectively compared with the individual probability ranges of the objects, in order to determine whether they overlap. If an overlap is identified, a response; signal that indicates the risk of a collision is generated.

A method and device for warning a driver of lane departure, wherein a first analyzer is used to detect the vehicle's lane departure based on image data and/or vehicle data and/or driver activity. The driver then receives a warning as a function of the detection by the first analyzer. In addition, a second analyzer for evaluating the driving situation is provided, which either performs the evaluation of the driving situation after the detection and via which the warning is suppressed as a function of the evaluation, or which alternatively performs an evaluation of the driving situation before the detection and via which a detection of lane departure is suppressed as a function of the evaluation. As a result, the driver receives highly reliable warnings of lane departure, and furthermore thanks to the evaluation of the driving situation erroneous warnings may be recognized highly reliably and as a result suppressed, so that the driver is not distracted unnecessarily and the product enjoys a high acceptance level among users.

A driver assistance device for warning a driver of a motor vehicle of a risk of departure from the lane or from the lane is described, having at least one image-transmitting sensor, an evaluation device, connected to the image-transmitting sensor, for detecting edge-of-lane and/or lane markings and/or edges of lanes in the area sensed by the image-transmitting sensor, and a warning device which is connected to the evaluation device, in which driver assistance device in addition at least one distance-transmitting sensor is connected to the evaluation device, with which sensor the distance from objects which are elevated with respect to the surface of the lane can be determined in the region of the edge of the lane, in particular of a structural boundary of the edge of the lane.

A device for acquiring data indicative of the path of a lane is provided. The device incorporates a lane detection sensing circuit, an object position sensing circuit that detects at least the distance of an object located in front of the vehicle and its directional angle relative to the direction of vehicle motion, and a sensing circuit for the vehicle's own motion. An estimating device is provided that is supplied with lane recognition measurement data, object position measurement data, and measurement data on the vehicle's own motion. As a function of the vehicle's own motion, the estimating device determines the lane curvature and/or the transverse position of an object ahead of the vehicle relative to the lane by estimation, using a presettable estimation algorithm including a dynamic vehicle motion model. The device preferably includes a Kalman filter for this purpose, and is used, for example, in road vehicles.

A method and a device for controlling the speed of a motor vehicle and its distance from a vehicle travelling in front are provided. The speed is controlled as long as no vehicle travelling in front is located within a prescribed detection area in front of the vehicle and the distance from the vehicle travelling in front is controlled if a vehicle is located in the detection area. The desired distance for the distance control is set after an instruction for a lane change to the left has been triggered, to a value which is smaller than the value before this instruction was triggered, but is at least as large as a prescribed minimum distance. Alternatively, the actual acceleration of the vehicle is limited to a prescribed maximum value if a vehicle travelling in front moves out of the prescribed detection area in front of the vehicle during the time that an instruction for a lane change to the right is set. In this way, fast overtaking maneuvers can be performed within the control and/or lane changes to the right can be carried out without undesired acceleration effects.

A method for determining variables characterizing vehicle handling is provided, in particular the attitude angle. Signals of measured variables are fed to a computing device. At least the attitude angle is determined in the computing device using equations of motion and using a two-track model of the vehicle.
