First Claim
Patent Images
1. A radar sensor for distance and cruise control of a motor vehicle, comprising:
- an arrangement configured to detect objects in front of the vehicle in a direction of travel and to ascertain at least a distance, a relative velocity, an azimuth angle of a recognized object with regard to the vehicle, and a position of a reflection point of a radar beam on the object,the arrangement further configured to ascertain a positional change in time of the reflection point of the radar beam on the object, and to ascertain a classification of the object as a function of the positional change in time of the reflection point.

Abstract
A radar sensor and a corresponding method for distance and cruise control of a vehicle are described; using this sensor and method, objects in front of the vehicle in the direction of travel are detected and at least the variables: distance, relative velocity, and azimuth angle of the detected objects are ascertained with regard to the vehicle, the change over time of the reflection point of the radar beam on the object and classification of the detected object being determined as a function of the change over time of the reflection point.
