Method for estimating the width of radar objects
First Claim
1. A method for estimating a width of radar objects in a position finding system for a motor vehicle, which has at least two angle-resolving radar sensors, the method comprising:
- combining into a group reflection points located by a plurality of the radar sensors, which are to be assigned to the same object on the basis of distance data and relative velocity data;
calculating lateral positions of the reflection points from the group;
calculating a difference of the lateral positions for various pairs of the reflection points; and
determining a maximum of the differences to determine an estimated value for a minimum width of the object.

Abstract
In a method for estimating the width of radar objects in a position finding system for motor vehicles, which has at least two angle-resolving radar sensors, the reflection points positioned by several of the radar sensors, which are to be assigned to the same object on the basis of their distance data and relative velocity data, are combined into a group, lateral positions of the reflection points from this group are calculated, the difference of the lateral positions is calculated for various pairs of these refection points, and the maximum of these differences is sought out to determine an estimated value for a minimum width of the object.
