A method for controlling a driver assistance system by using a stereo camera system having a first and a second camera, the method having a step of reading in, a first image being read in from the first camera and a second image being read in from the second camera. The method furthermore comprises a step of forming, a cost function being generated by using the first and the second image. Furthermore, in a further method step of determining, a frontoparallelity parameter representing the frontoparallelity of an object with respect to the stereo camera system is determined by using a global minimum of the cost function. Finally, the method comprises a step of using, the frontoparallelity parameter being used to control the driver assistance system.

A method for producing a masking instruction for a camera of a vehicle, the method including a setting step, a transforming step, and a storing step. In the setting step, interpolation points of a field-of-view boundary are set in a vehicle coordinate system using three-dimensional model data of the vehicle, the interpolation points being set from a camera perspective that is modeled in the model data. In the transforming step, vehicle coordinates of the interpolation points from the vehicle coordinate system are transformed into a spherical coordinate system to obtain spherical coordinates of the interpolation points. In the storing step, a mask curve defined by the interpolation points, is stored in the spherical coordinate system in order to produce the masking instruction.

A radar sensor including an antenna array having multiple antenna elements situated next to one another and at least one feeding point at an outer antenna element. The antenna elements are connected in series via delay lines. The radar sensor has at least two transmitting and receiving units which are each suitable for generating and evaluating a radar signal at a predefined frequency. The at least two transmitting and receiving units are connected to a feeding point of the antenna array. The frequencies of the radar signals of the at least two transmitting and receiving units are predefinable independently of one another.

Radar sensor

An antenna has an antenna body having a plurality of first antenna elements, which are disposed along a first straight line. A hollow conductor, which extends between the first antenna elements, is disposed in the antenna body. The first antenna elements are developed as openings running between the hollow conductor and a surface of the antenna body. The antenna is designed to radiate a signal in a spatial direction that is a function of a frequency of the signal. The antenna body has an electrically insulating material that is coated with a conductive material.

Antenna

An antenna has an antenna body having a plurality of first antenna elements situated along a first straight line. The antenna body includes a first conductive grounded surface and a second conductive grounded surface, the first and second grounded surfaces being situated essentially parallel to one another. A dielectric is situated between the first and second grounded surfaces. A signal conductor is also situated between the first and second grounded surfaces. The first antenna elements are designed as apertures situated above the signal conductor in the first grounded surface. Furthermore, the antenna is designed to emit a signal in a direction in space, depending on a frequency of the signal. At least two of the first antenna elements differ from one another in such a way that their power emissions are different.

In a method for checking the plausibility of objects in driver assistance systems for motor vehicles is described, two measured variables are derived from position data from two object position-finding systems of the vehicle that operate independently of one another, for an object located by the two position-finding systems, one variable for each position-finding system, these variables representing one and the same physical parameter, and the two measured variables are then checked for consistency, which is characterized by the fact that the parameter is the time to collision of the vehicle with the object, which is calculated in advance.
