Abstract

A method for sensing objects in the surrounding field of vehicles, input values being determined by a plurality of sensors, and positional information pertaining to the objects being derived on the basis of a comparison with stored data, as well as a device for implementing the method.

Claims

1. A method for sensing objects in the surrounding of a vehicle, comprising the steps of:

determining input values with respect to the objects by a plurality of sensors; and

deriving positional information pertaining to the objects from the input values on the basis of a comparison with stored data.

2. The method as recited in claim 1 wherein the sensors are radar sensors.

3. The method as recited in claim 1 further comprising in an additional step of determining the distances to the objects from the input values supplied by the sensors.

4. The method as recited in claim 3 further comprising suppressing errors in the input values.

5. The method as recited in claim 1 further comprising determining relative velocities between the objects and the vehicle.

6. The method as recited in claim 5 wherein the relative velocities are determined from successively measured distance data on the objects.

7. The method as recited in claim 5 wherein the relative velocities are determined from a Doppler measurement.

8. The method as recited in claim 1 further comprising defining a region in the vehicle surroundings to be considered.

9. The method as recited in claim 1 wherein stored positional data from preceding measurements are substituted as the stored data when the positional information temporarily is not derivable.

10. A device for sensing objects in the surrounding field of vehicles, comprising:

a plurality of sensors; and

an analyzing unit having a classification device for deriving positional information on the objects on the basis of a comparison with data stored in a memory unit.

11. The device as recited in claim 10 wherein the sensors are radar sensors, optical sensors, or a combination of radar sensors and optical sensors.

12. The device as recited in claim 10 wherein the analyzing unit or another device is capable of recognizing failure of a sensor of the plurality of sensors.
