Patent number: 10821875Abstract: A method for depth perception based on vehicle headlights arranged on both sides of a vehicle includes projecting, by a first vehicle headlight, a first characteristic light pattern onto a projection surface and projecting, by a second vehicle headlight, a second characteristic light pattern. The method also includes capturing an image of the projection surface using an image capturing unit of the vehicle, calculating a frequency representation of the first and second characteristic light patterns in the captured image, and calculating, by evaluating frequency components in the frequency representation of the first and second characteristic light patterns, a coverage coefficient which is correlated with the degree of mutual covering of the first and second characteristic light patterns. The method further includes comparing the coverage coefficient with a coverage threshold value and displacing the first and second characteristic light patterns relative to one another if there is insufficient mutual covering.Type: GrantFiled: June 17, 2019Date of Patent: November 3, 2020Assignee: Dr. Ing. h.c.F.

Patent number: 10497147Abstract: A method for determining a location relationship between a camera and a headlight of a vehicle includes positioning the vehicle at a distance in front of a surface exhibiting a calibration pattern, ascertaining the distance between the calibration pattern and the vehicle, projecting a pattern onto the surface using a headlight of the vehicle, and detecting characteristic features in the projected pattern. The method further includes performing the previous steps for at least one additional distance between the vehicle and the surface. In addition, the method includes interpolating positions of detected characteristic features that correspond in each case to one another at the different distances using a linear function, determining an intersection of the ascertained linear functions, and determining the location relationship between the camera and the headlight of the vehicle on the basis of the position of the intersection of the ascertained linear functions relative to the camera.Type: GrantFiled: October 23, 2018Date of Patent: December 3, 2019Assignee: DR.

Patent number: 9873373Abstract: A method for regulating a brightness of a luminous unit includes regulating the luminous unit by a pulse width modulator which provides an electric current having a predefined current value Y at a start time t0; modulating the electric current to a predefined brightness value at the start time t0 with a frequency of switching pulses that is chosen depending on a predefined brightness value; and progressively reducing the current value of respective switching pulses of the pulse-width-modulated electric current to a current value Y? proceeding from a start time t0 until a target time t1. The current value Y? is chosen in such a way that the luminous unit is luminous with the predefined brightness value upon a permanent supply with an electric current corresponding to the current value Y?. The respective switching pulses of the electric current are lengthened in their duration until a continuous electric current arises.Type: GrantFiled: April 24, 2017Date of Patent: January 23, 2018Assignee: DR.
