Abstract

The invention relates to a method and a device for monitoring the function of a driver assistance system, the environment of a vehicle ( 20 ) being detected by means of at least one sensor ( 1,111, 121, 131 ) and sensor data of the environment of the vehicle ( 20 ) being generated, from said data at least one measurement variable (B, D, R, R 1 , R 2 , X) is determined and is compared to reference values for said measurement variable (B, D, R, R 1 , R 2 , X). The result of the function monitoring is subsequently output and/or stored in accordance with the result of the comparison.

First claim

1 - 11 . (canceled)

12 . A method of monitoring whether a driver assistance system is properly functional, comprising steps:
detecting an environment of a vehicle by at least one sensor, generating sensor data regarding the environment of the vehicle, determining at least one measurement variable from the generated sensor data, comparing the at least one measurement variable to reference values for the at least one measurement variable, and producing a corresponding comparison result, based on and dependent on the comparison result, producing an indication of whether the driver assistance system is functioning properly, and outputting and/or storing the indication.

13 . The method according to claim 12 , further comprising providing additional sensor data of at least one additional sensor, and wherein the determining of the at least one measurement variable comprises determining at least one second measurement variable from the additional sensor data, and determining or improving a first measurement variable based on the at least one second measurement variable.

14 . The method according to claim 12 , wherein the at least one measurement variable comprises a spatial expanse of an object detected in the environment of the vehicle.

15 . The method according to claim 12 , wherein the at least one measurement variable comprises a spatial relative distance between the vehicle and an object detected in the environment of the vehicle.

16 . The method according to claim 12 , wherein the at least one measurement variable comprises a spatial distance between objects detected in the environment of the vehicle.

17 . The method according to claim 12 , wherein the determining of the at least one measurement variable comprises a one-time measurement of a variable in the generated sensor data.

18 . The method according to claim 12 , wherein the determining of the at least one measurement variable comprises plural temporally successive measurements of a variable in the generated sensor data.

19 . The method according to claim 12 , wherein the reference values comprise historical and/or stored reference values for the measurement variable.

20 . The method according to claim 12 , further comprising providing historical and/or stored reference values, and wherein the determining of the at least one measurement variable comprises using the historical and/or stored reference values for the measurement variable.

21 . A device for monitoring whether a driver assistance system is properly functional, comprising:
at least one sensor for detecting an environment of a vehicle, a determination means configured and arranged to generate sensor data of the environment of the vehicle and to determine at least one measurement variable from the generated sensor data, a comparison means configured and arranged to compare the at least one measurement variable to reference values for the at least one measurement variable and to produce a corresponding comparison result, and an output and/or storage means configured and arranged to output and/or store an indication of whether the driver assistance system is functioning properly based on and dependent on the comparison result.

22 . The device according to claim 21 , further comprising a data connection to a data storage memory that contains data on historical and/or stored reference values of the determined measurement variable in a machine-readable form.

23 . A combination comprising a driver assistance system and the device according to claim 21 .
