A method and device for vehicle-supported object detection. A pulse is emitted into the surroundings using a transducer situated in a vehicle, and the pulse, which is reflected back by an object in the surroundings, is recorded using the transducer. The transducer and the object move relative to each other. The emission and/or the recording are carried out according to a directional characteristic of the transducer, which has at least two directional lobes. Signal components of the reflected pulse, which have different frequency shifts, are separated from one another on the basis of the frequency shift or are assigned to respectively one of the directional lobes. An object detection is carried out in each case for the different signal components and the assigned directional lobes.

A method for calibrating a parking aid, which is configured to actively control a steering angle of a vehicle, by: automatically detecting a parking space with the aid of sensors and calculating a target course in light of the detected parking space. The steering angle is controlled based on the calculated target course, with a controllable actuator. The method accounts for an error by the actuator by: determining an actual course, which results from controlling according to the target course; comparing the actual course to the target course and ascertaining the error resulting from the comparison; and generating a correction parameter, which is linked to the error by a monotonic function. The correction parameter allows the actuator's behavior to be considered. Controlling the steering angle is done based on a combination of the set angle with the correction parameter. A related controller for implementing the method is also described.

A method for assisting a driver of a motor vehicle during a driving maneuver, in which the surroundings laterally next to the vehicle are registered using a first sensor in the rear region and a second sensor in the front region. With the aid of distance values of the first sensor from an object, taken one after another during a short travel segment, an object edge is determined and a contact point is established which is located at the place at which a straight line, extending the object edge and a straight line bordering the registration range of the second sensor, which does not register the object, on the side of the first sensor, intersect. Also described is a device for implementing the method.

A method for assisting a driver of a vehicle in a driving maneuver in which the vehicle is guided automatically along a previously calculated trajectory, or the lateral guidance for travel along the trajectory is carried out automatically, and after the driving maneuver is completed, the steering of the vehicle is returned to the driver, information being provided to the driver concerning the vehicle's surroundings and suitable steering settings before and/or during the transfer of the steering to the driver. Also described is a device for carrying out the method, including a steering arrangement for steering the vehicle along a previously calculated trajectory as well as an output arrangement for outputting information concerning the vehicle's surroundings and suitable steering settings to the driver before and/or during the transfer of the steering to the driver.
