  • Patent number: 7991526
    Abstract: A method and a device for controlling at least one object detection sensor for a motor vehicle, the at least one sensor being switchable between a plurality of operating modes; a plurality of functions for evaluating the objects detected, using the object detection sensor, being able to access randomly the at least one sensor and a switchover between the operating modes being selected as a function of the instantaneously accessing assistance functions, and a coordinator is provided between the function evaluation devices and the at least one sensor; each function accessing the at least one sensor transmits to the coordinator a biasing probability distribution function, respectively, and the at least one sensor transmits to the coordinator a detection probability density function for each operating mode that is able to be activated, and the coordinator selects the most suitable operating mode for each function accessing the at least one sensor.

  • Patent number: 7714771
    Abstract: A method and device are provided for measuring distance and relative speed of a plurality of objects with the aid of an FMCW radar, transmitted signals being reflected by objects, and the reflected signals being received and mixed with the transmitted signals. A combination of distance and relative speed values is assigned to the mixer output frequencies of each frequency ramp for each object, and the distance and relative speed of a possible object are determined from points of intersection of a plurality of distance and relative speed combinations. The apparent (unreal) objects are eliminated by modifying the frequency slope of at least one frequency ramp according to the random principle in a subsequent measurement cycle.

  • Patent number: 6691003
    Abstract: Method and device for state estimation in a system for automatic longitudinal and/or transverse regulation in a motor vehicle, operating according to the radar principle and/or the lidar principle, in particular for detecting soiling and/or blindness of a sensor is disclosed. The state estimation is dependent upon at least two indicators, which are formed from the signals received and/or transmitted by the sensor.
