Abstract: A method and device for determining an anomalous driving pattern of a neighboring vehicle using a vehicle camera and/or other sensor is described. Image data is received and if suitable lane markings are detected, a reference trajectory is derived from the detected lane markers. Otherwise, a reference trajectory is derived from a motion of the present vehicle. A trajectory of the neighboring vehicle is determined, characteristic parameters of the detected trajectory are derived, and the characteristic parameters are compared with predetermined trajectory data. Based on the comparison it is determined if the trajectory of the neighboring vehicle is an anomalous trajectory and in one case an alert signal is generated.

Abstract: A method and device for detecting objects in the dark using a vehicle camera and a vehicle lighting system. The method comprising: a) taking a first image with the vehicle lighting switched off; b) taking a second image with the vehicle lighting switched on; c) generating a differential image of the second and first images; and d) detecting reflective objects using the differential image.

Abstract: In a method for triggering a driver assistance function of a subject vehicle, image data of surroundings in front of the vehicle is generated by a camera and supplied to an analyzing unit. A driver assistance function is triggered upon detection of a brake light of an other vehicle in the image data. A geometric region of the detected other vehicle is determined as exhibiting the highest pixel brightness values and the color red. The geometric region is detected as a raised brake light of the other vehicle if the geometric region is positioned essentially in the middle of the horizontal structure of the other vehicle, or at least a predetermined height above the roadway, or at least a predetermined distance below a rear window of the other vehicle.

Abstract: The invention relates to a method for triggering a driver assistance function of a vehicle, in which image data of that part of the surroundings of the vehicle which is in front of the vehicle is generated by means of a camera and supplied to an analyzing unit for the purpose of analysis and the driver assistance function is triggered upon detection of a stop light (1) of a further vehicle (10) detected as an object, said stop light (1) being contained in the image data. According to the invention, at least one geometric region of a detected object (10) is determined in the image data, the pixels of said region essentially exhibiting the highest brightness values in the image data and the spectral color red, and the geometric region is detected as a raised stop light (1) of the further vehicle (10) if the geometric region is detected to be positioned essentially in the middle of the horizontal structure of the detected object (10).
