  • Patent number: 9638796
    Abstract: A radar sensor for motor vehicles, having a transmitting antenna in the form of a planar group antenna having multiple antenna elements situated side by side on a shared planar substrate, and having a feed network and a switching device for supplying microwave power to the antenna elements. The antenna elements are situated at equal distances in at least one row; the feed network is designed for supplying the antenna elements with the microwave power having a phase shift which increases at constant increments from one end of the row to the other; and the switching device is designed for controlling the supply of the microwave power to the antenna elements in such a way that, depending on the operating mode, the supply is implemented in a mirror-inverted fashion from opposite ends of the at least one row.

  • Publication number: 20160315628
    Abstract: Described is a frequency generator for producing a frequency ramp. The frequency generator includes a first voltage controlled oscillator, which has a plurality of switchable sub-bands and is designed to produce a first frequency signal, wherein a switching from one sub-band to a neighboring sub-band occurs at predetermined first switching locations, as well as a second voltage controlled oscillator, which has a plurality of switchable sub-bands and is designed to produce a second frequency signal. A switching from one sub-band to a neighboring sub-band occurs at predetermined second switching locations. The sub-bands of the second voltage controlled oscillator are arranged offset in frequency relative to the sub-bands of the first voltage controlled oscillator.

  • Publication number: 20110172881
    Abstract: In a method for stabilizing a vehicle motion of a single-track motor vehicle, e.g., a motorcycle, an angle of inclination of the motor vehicle relative to the roadway is recorded via inclination sensors and, after the processing of the angle of inclination in a computing device, a control signal based on this is supplied to a control device for bringing about a stabilization intervention in the vehicle motion, the attitude angle of the motor vehicle being recorded and jointly processed in the control device, using at least one attitude angle recording sensor.
