摘要:
Future vehicle headlamps will provide light functions, such as, for example, town light, country road light, motorway light, full beam, poor weather light, etc. A method and a device is therefore provided with which the light functions of vehicle headlamps are controlled in a reliable manner. The device essentially comprises front headlamps with a dipped headlight and full beam, and at least one variable actuator with which different light functions can be realized. In order to select a light function, the variable actuator is set to a predetermined, fixed position. In this case, it is not possible to select a light function in the region between the dipped headlight and the full beam, there being no means of locking the actuator in the intermediate region between the position of the actuator for the dipped headlight and the position for full beam. Only a light function which is matched to the driving situation and can be selected in a reliable manner is therefore possible.

A device for controlling a driving light of a vehicle includes a headlight with a light source, a device for pivoting a produced light distribution and an optical element that provides adjustable light distribution. The optical element includes a light passage opening pivotable into an optical axis of the light source. A beam of the light distribution is limited or deflected such that a limited light field is produced in a pre-settable region in front of the vehicle, which light field has an external form of the light passage opening. Further light passage structures provide a “high beam” or “partial high beam” light pattern and thereafter the “high beam” light pattern by turning, pivoting and/or displacing the optical element in one direction, and another further light passage structure provides a “motorway” and thereafter a “country road” light pattern by turning, pivoting and/or displacing the optical element in an opposite direction.
摘要:
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 steering system (1) of a vehicle, having a steering wheel (2) which is connected mechanically to the steerable vehicle wheels (11) via a steering column (3). A superimposition actuator (26) which can be actuated independently of the driver by a control device (25) is provided for generating a superimposition variable (U). A superimposition device (6) superimposes a steering wheel variable (δH) which describes the steering actuation of the steering wheel (2) and the superimposition variable (U) to form an output variable. A steering actuator (19) sets a steering angle (δL) at the steerable vehicle wheels (20) as a function of the output variable. An actuating device (27) is provided which is actuated by the control device (25) in order to generate an actuating device torque (MS) which acts on the steering column. Here, the control device (25) at the same time actuates the superimposition actuator (26) and the actuating device (27), with the result that the steering angle (δL) and a reaction moment (MR) which results from the superimposition variable (U) and the actuating device torque (MS) and feeds back on the steering wheel (2) are influenced independently of the driver.

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.

摘要:
A motor vehicle has a rear-end impact warning device, which determines at least the distance to a following vehicle from the backscatter of a signal by means of a surroundings sensor system which is arranged at the rear of the vehicle. The rear-end impact warning device outputs light signals in a situation-dependent flashing mode by means of lights (e.g., brake lights) at the rear in order to provide the traffic behind with a warning of a rear-end impact if a following vehicle approaches to a critical distance. A braking process is sensed by means of a deceleration-sensing means, and a brake flashing mode is predefined if a vehicle approaches to a critical distance and at the same time a braking process is occurring.
