The invention concerns a system for informing the driver regarding sections of road lying ahead and being considered for a passing process. For this, the system employs, on the basis of known navigation systems, special data from digital maps in order to carry out an evaluation of ahead lying sections of road according to various criteria. Vehicle specific data, driver profiles or data regarding the actual weather situation can be incorporated into the evaluation. As a result, ahead lying stretches of road are classified as to their suitability for a passing maneuver, and the driver is informed, for example, by a display.

The projection headlight has a reflector (10), a light source (20) arranged in a peak region of the reflector, a stop or mask (30) arranged in front of the reflector and a projection lens (40) arranged in front of the stop or mask. The reflector (10) and the light source (20) are pivotally mounted and connected with each other so as to rotate together about a rotation axis (60) arranged in the vicinity of a second principal point of the projection lens (40). The illumination device has at least two of these projection headlights, advantageously on opposite sides of the vehicle. The angular orientations of the reflectors (10) are controlled independently of each other in the illumination device.

The invention relates to a method for operating a headlight (12) of a motor vehicle (10), which headlight (12) comprises a plurality of light emitting diodes, by receiving a request signal for a high-beam mode; determining a road class of a roadway on which the motor vehicle (10) is located; activating a first group of the plurality of light emitting diodes for providing a first high-beam distribution (20) with the headlight (12) in the event that a road class different from a highway (18) is determined; and activating a second group of the plurality of light emitting diodes for providing a second high-beam distribution (26) with the headlight (12) in the event that a highway (18) is determined as the road class.
摘要:
A method for controlling a light emission of at least one headlight of a, includes determining structure information which represents the presence of a structure which at least partially encloses a roadway traveled by the vehicle. The method also includes generating a control signal for controlling the light emission, using the structure information.

Disclosed herein are a method and a system for recognizing a space of a road shoulder using an ultrasonic wave sensor, a radar and an imaging device. The method includes: controlling the radar to transmit a radar beam within a preset range based on the vehicle location; detecting a fixed object located within the preset range using a reflective wave of the radar beam received by the radar; calculating a distance between the fixed object and the vehicle using the radar when the fixed object is located within the preset range; detecting a solid line lane marking in a front image of a travel lane obtained from the imaging device; and recognizing the calculated distance between the fixed object and the vehicle as a space width of the road shoulder when the solid line lane is in the front image of the travel lane.
摘要:
A method for traffic-dependent control of beam projection of headlights of motor vehicles requires the passing of images from at least two image recording units to a control unit for evaluation. A road profile is generated as a three-dimensional image by reference to the images from the at least two image recording units so that predictive control of the vehicle lighting is carried out on a basis of the determined road profile.
摘要:
A light unit 1 for a vehicle has a driving-environment detecting device 2 for detecting information (the shape of the road, the position of the vehicle, whether or not oncoming and preceding vehicle exist, the traffic volume density and ambient luminous intensity) indicating a driving environment provided by a path through which a vehicle is driven. A mode determining device 3 determines a driving mode which is included in driving modes classified in accordance with combinations of information detected by the driving-environment detecting device 2 and which is dynamically changed when the driving environment is changed during driving of the vehicle. In accordance with an instruction signal supplied from the mode determining device 3 to an illumination control device 4 and corresponding to the driving mode, illumination which is performed by the light unit 5 is controlled.

A lighting device in which the vehicle advancing direction at which a driver aims is predicted, and the irradiating direction and irradiating range of a lighting device are controlled by comparing the result of the prediction to the information of the profile of a road on which the vehicle is running at present. The lighting device (1) includes a road profile calculating device (2) for finding an advancing direction of the vehicle in the case where the vehicle advances along a road on which the vehicle is running at present, in accordance with the map information including the road profile and the present position information of the vehicle; and a vehicle advancing direction predicting device (3) for predicting an advancing direction of the vehicle intended by a driver, by an operation signal given by the driver or detection information of the vehicle running state. The irradiation controller device (4) compares the direction data of the road profile calculating device (2) with the direction data of the vehicle advancing direction predicting device (3), the irradiation control of the lighting device (5) is conducted by the road profile in accordance with the direction data of the road profile calculating device (2) when a difference between them is in an allowable range, and the irradiation control of the lighting device (5) is conducted by the direction data of the vehicle advancing direction predicting device (3) when the difference between them is out of the allowable range.
摘要:
A head lamp device for a vehicle in which a light distribution can be properly adjusted in response to a state of a road or a running environment and visibility can be improved is provided. The head lamp device for a vehicle capable of adjusting a lighting region in a forward direction of the vehicle comprises proper vehicle position sensing means for sensing a proper vehicle running position in a lateral direction of a road, and control means for calculating a distance from the proper vehicle running position to a center line on the road and adjusting a lighting region of the head lamp in such a way that the lighting region is expanded more and more toward the center line as the calculated distance is longer and longer.
