A method for monitoring the surroundings of a vehicle, the surroundings behind the vehicle being detected with the aid of ultrasonic sensors and with the aid of at least one imaging sensor, a warning signal being output when an object that has a distance to the vehicle smaller than a predefined minimum distance is detected with the aid of ultrasonic sensors, a trailer of the vehicle being recognized with the aid of the imaging sensor, and the warning signal not being output when the object is the trailer recognized by the imaging sensor.

A method for mapping surroundings of a vehicle, objects in the surroundings of the vehicle being detected with the aid of sensors and particular detected objects being described by two coordinate points and also by a position fuzziness assigned to the particular coordinate point, the coordinate points and the position fuzziness values being stored in an interface in the form of data which may be accessed by driver assistance systems of the vehicle. A method is also described for ascertaining the collision probability of a vehicle with an object, in which the surroundings of the vehicle are initially mapped using the method for mapping the surroundings of a vehicle, a travel path to be traveled by the vehicle is ascertained in a subsequent step, and the degree of overlap between the object and the travel path and also the collision probability are finally determined, taking the position fuzziness into account.

A method and an apparatus for lane recognition for a vehicle that is equipped with an adaptive distance and speed control system are provided, the adaptive distance and speed controller having conveyed to it, using an object detection system, the relative speed of detected objects, a variable for determining the lateral offset of the detected objects with respect to the longitudinal vehicle axis, and the speed of the host vehicle. From the relative speed of the objects and the host-vehicle speed, a determination is made as to whether an object is oncoming, stationary, or moving in the same direction as the host vehicle. In combination with the calculated lateral offset of the detected object with respect to the longitudinal vehicle axis, the number of lanes present and the lane currently being traveled in by the host vehicle are determined.
