Method, software program product, and device for safety-oriented speed monitoring of an autonomous mobile unit

An apparatus for safety-oriented speed monitoring of an autonomous movement unit, the apparatus comprising:

• at least one locomotion device with a movement detection system, wherein a first movement vector is determinable based on measured values from the movement detection system;
• at least one environment detection system situated on the autonomous movement unit, wherein a second movement vector of the movement unit is determinable from second data based on measured values from the environment detection system;
• a diagnostic unit configured to check the first data and the second data;
• and
• a programmable controller configured to:
• check the first movement vector and the second movement vector using a cross-comparison;
• make safety-oriented decisions for the movement unit based on a checking result obtained from the diagnostic unit,
• wherein a statement on a validity and a movement vector considered to be safety-oriented are output-able as the result;
• and
• activate protective fields based on the statement of the validity and the movement vector,
• wherein a plausibility check is previously performed on the first data, on the second data, or on the first data and the second data, and checks whether there is noise in determined values, and
• wherein the first data and the second data are checked for plausibility independently of one another.

A non-transitory computer-readable storage medium that stores instructions executable by one or more processors for safety-oriented speed monitoring of an autonomous movement unit comprising at least one locomotion device with a movement detection system, and at least one environment detection system situated on the autonomous movement unit, the instructions comprising:

• determining a first movement vector from first data relating to the autonomous movement unit based on measured values from the movement detection system using a first method;
• determining a second movement vector of the autonomous movement unit from second data based on measured values from the environment detection system using a second method;
• and
• checking the first movement vector and the second movement vector using a cross-comparison and outputting a statement on a validity and a movement vector considered to be safety-oriented as a result of the checking;
• and
• activating protective fields based on the statement on the validity and the movement vector,
• wherein a plausibility check is previously performed on the first data, the second data, or the first data and the second data, and
• wherein the first data and the second data are checked for plausibility independently of one another, and the plausibility check checks whether there is noise in determined values.
